The problems considered, however, belong equally to normal psychology in that they are problems of psycho-physiological functions and mechanisms. I have made no attempt to develop any particular school of psychological theory but rather, so far as may be, to gather to- gether the knowledge already gained and lay a foundation which can be built upon by any school for the solution of particular problems, especially those of special pathology. I have therefore en- deavored to avoid controversial questions although this, of course, has not been wholly possible, and indeed so far as special pathological conditions (the psychoses) have been considered, it has been for the purpose of providing data and testing the principles adduced. The inductive method, alone, I believe, as in the physical sciences, can enable us to arrive at sound conclusions justify the formulation of theo- ries to explain psychological phenomena. Because of the very difficulties of this field of research one of which is that of submitting to experimental condi- tions complex psychological phenomena having so many factors it is all the more incumbent that the inductive method should be employed. To my way vi PREFACE of thinking we should begin at the bottom and build up bit by bit, drawing, as we go, no wider conclu- sions than the facts developed warrant; or if we do, these should be recognized clearly as working hy- potheses or speculative theories. Skyscrapers should not be erected until the foundations have been examined to see if they will bear the superstructure. That I have wholly succeeded in so rigorously re- stricting my own endeavors I can scarcely hope. I trust, however, that I have succeeded in consistently maintaining the distinction between facts and their interpretations. The present volume consists of selected lectures (with the exception of four) from courses on ab- normal psychology delivered at the Tufts College Medical School (1908-10) and later at the University of California (1910).* These again were based on a * In this connection it is a satisfaction to the author to note that more recently a committee was appointed by the American Psychological Association (December, 1911) to investigate the rela- tion of psychology to medical education. This committee, after an ex- tensive inquiry by correspondence with all the medical schools of the country, has made a report (Science, Oct. 17, 1913) based upon the preponderating opinion of the best medical schools and of the schools as a whole. The second (in substance) and third conclusions reached in the report were as follows: 2nd: For entrance in certain schools requiring a preliminary college training of greater or less length an introductory or pre- medical course in psychology should be required in the same way as they now require chemistry, biology, physics, etc., or, in lieu thereof, a course in the medical schools. 3rd: "It is the belief of most of the best schools that a second course in psychology should precede the course in clinical psychiatry and neurology. This course should have more of a practical nature, PREFACE vii series of papers on the Unconscious published in the Journal of Abnormal Psychology (1908-9) of which they are elaborations. Since the lectures were deliv- ered a large amount of new material has been incor- porated and the subject matter considered in more detail and more exhaustively than was practical be- fore student bodies. The four additional lectures (X, XI, XII and XIII) appeared in abbreviated form in the same Journal (Oct., Nov., 1912) under the title "The Meaning of Ideas as Determined by Unconscious Settings." The lecture form has been retained, offering as it does many advantages where, in the exposition of a difficult subject, much that is elemental needs to be stated. As the subconscious and its processes are funda- mentals both in the structure of personality and in and should deal especially with abnormal mental processes and with the application of psychological principles and facts to medical topics. Although this course should deal chiefly with psychopath- ology, it should not be permitted to develop, or degenerate, into a course in psychiatry, neurology or psychotherapeutics. This course should be clinical in the sense that, as far as possible, clinical material should be the basis of the course, but it should not be clinical in the sense that the students are given particular cases for the purpose of diagnosis or of treatment. The functions of the courses in psychiatry and neurology should not be assumed by this course. ' ' The courses, from which I have selected twelve lectures for my present purpose, were designed for just such instruction as is recom- mended in this report. They were, I believe, the first to be given on these subjects in any medical school or college in this country. Necessarily they covered a wider range of topics than the lectures now published which more properly serve as an introduction to the general subject. viii PREFACE the many mechanisms through which personality, normal and abnormal, finds expression, the first eight lectures are devoted to its exposition. Indeed, as has been said, the subconscious is not only the most important problem of psychology, it is the problem. The study of its phenomena must be pre- liminary to that of the functioning mechanisms of both the normal mind and of those special patholog- ical conditions the psycho-neuroses which modern investigators are tracing to its perversions. In a recently published article M. Bergson con- cludes with the following prophesy: "To explore the most sacred depths of the unconscious, to labor in what I have just called the subsoil of conscious- ness, that will be the principal task of psychology in the century which is opening. I do not doubt that wonderful discoveries await it there, as important perhaps as have been in the preceding centuries the discoveries of the physical and natural sciences. That at least is the promise which I make for it, that is the wish that in closing I have for it. ' ' And yet one reads and hears all sorts of contra- dictory statements, made by those who it is pre- sumed should know, regarding the actuality of the subconscious. Thus one or another writer, assum- ing to know, states most positively that there is no such thing as the subconscious. Others, equally em- phatic, postulate it as an established fact rather than a theory, or assume it as a philosophical con- cept or hypothesis to explain particular phenomena. *"The Birth of the Dream," The Independent, Oct. 30, 1913. PREFACE ix One difficulty is that the term, as commonly used, has many meanings, and it has followed that dif- ferent writers have assumed it with respectively different meanings. Consequently the subconscious as an actuality has been unwittingly denied when the intent has been really to deny some particular meaning or interpretation, and particular meanings have been subsumed which are only philosophical concepts. There should be no difficulty in deciding what the facts permit us to postulate. The subconscious is a theory based upon observed facts and formulated to explain those facts. There are many precise phe- nomena of different kinds which can only be ex- plained as due to explicitly subconscious processes, that is, processes which do not appear in the con- tent of consciousness ; just as the phenomena mani- fested by radium can only be explained by emana- tions (or rays) which themselves are not visible and cannot be made the object of conscious experience. In each case it is the manifestations of such proc- esses of which we become aware. Subconscious processes and radio-activity stand on precisely the same basis so far as the determination of their actuality is concerned. (The latter have the advan- tage, of course, in that being physical they are sub- ject to quantitative measurement.) Such being the case it ought to be possible to construct the theory of the subconscious by inductive methods on the basis of facts of observation just as any theory of the physical sciences is constructed. x PREFACE This task I have set before myself as well as that of giving precision to our conception of the theory and taking it out of the domain of philosophical con- cepts. With this purpose in view I have endeavored to apply the method of science and construct the theory by induction from the data of observation and experiment. I dare say this has been a some- what ambitious and some will say, perhaps, over- bold undertaking. Undoubtedly, too, this attitude toward this and other individual problems has not been always consistently maintained, nor perhaps is it completely possible in the present state of the science. Our formulations should be as precise as possible and facts and concepts of a different order should not be included in one and the same formula. I have, accordingly, divided the subconscious into two classes, namely (1) the unconscious, or neural dis- positions and processes, and (2) the coconscious, or actual subconscious ideas which do not enter the content of conscious awareness. An unconscious process and a coconscious process are both therefore subconscious processes but particular types thereof the one being purely neural or physical and the other psychological or ideational. The soundness of the conclusions reached in this work I leave to the judgment of my critics, of whom I doubt not I shall have many. I do not hesitate to say, however, that it is only by practical familiarity with the phenomena of mental pathology and arti- ficially induced phenomena (such as those of hyp- PREFACE xi nosis, suggestion, etc.), requiring a long training in this field of research (as in other scientific fields), that we can correctly estimate the value of data and the conclusions drawn therefrom; and even then many of our conclusions can be regarded as only provisional. In these lectures I have also endeavored (Lectures XIV-XVI) to develop the phenomena of the emo- tional innate dispositions which I conceive play one of the most fundamental parts in human personality and in determining mental and physiological be- havior. Experimental methods and the well-known clinical methods of investigation have been employed by me as far as possible. The data made use of have been derived for the most part from my own observations, though confirmatory observations of others have not been neglected. Although a large number and va- riety of subjects or cases have been studied, as they have presented themselves in private and hospital practice, the data have been to a large extent sought in intensive studies, on particular subjects, carried on in some cases over a period of many years. These subjects, because of the ease with which sub- conscious and emotional phenomena were either spontaneously manifested or could be experiment- ally evoked, were particularly suitable for such studies and fruitful in results. It is by such inten- sive studies on special subjects, rather than by cas- ual observation of many cases, that I believe the adi PREFACE deepest insight into mental processes and mechan- isms can be obtained. In conclusion I wish to express my great obliga- tion to Mrs. William G. Bean for the great assist- ance she has rendered in many ways in the prepa- ration of this volume. Not the least has been the transcription and typing of my manuscript, for the most part written in a quasi shorthand, reading the printer's proofs, and much other assistance in the preparation of the text for the press. For this her practical and unusually extensive acquaintance with the phenomena has been of great value. I am also indebted to Mr. Lydiard Horton for kindly reading the proofs and for many helpful suggestions in clarifying the arrangement of the text a most difficult task considering the colloquial form of the original lectures.

I begin with the study of this problem because a knowledge of the facts which underlie the theory of memory is a necessary introduction to an under- standing of the Unconscious, and of the part which subconscious processes play in normal and abnor- mal mental life.* Speaking more specifically, with- out such a preliminary study I do not believe we can interpret correctly a very large number of the disturbances of mind and body which are traceable to the activity of subconscious processes and with which we shall later have to do. If we consider memory as a process, and not as specific phases of consciousness, we shall find that it is an essential factor in the mechanisms underlying a large variety of phenomena of normal and abnor- mal life. These phenomena include those of both * I divide the Subconscious into two parts, namely the Unconscious and the Coconscious. See preface and Lecture VIII. 1 2 THE UNCONSCIOUS mind and body of a kind not ordinarily conceived of as manifestations of memory. I would have you dwell in your minds for a moment on the fact that I make this distinction between memory as a process and memory as a phase of consciousness or specific mental experience. What we ordinarily and con- ventionally have in mind when we speak of memory is the conscious thought of some past mental experi- ence. But when we conceive of memory as a process we have in mind the whole mechanism through the working of which this past experience is registered, conserved, and reproduced, whether such reproduction be in consciousness or below the surface of consciousness. Memory is usually looked upon as something that pertains solely to consciousness. Such a conception is defensible if the meaning of the term is restricted to those facts alone which come within our conscious experience. But when we consider the mechanism by which a particular empirical fact of this kind is introduced into consciousness we find that this con- ception is inadequate. We find then that we are obliged to regard conscious memory as only the end result of a process and, in order to account for this end result, to assume other stages in the process which are not phases of consciousness. Though the end result is a reproduction of the ideas which con- stituted the previous conscious experience, this re- production is not the whole process. More than this, the conscious experience is not the only experience that may be reproduced by the THEORY OF MEMORY AS A PROCESS 3 process, nor is the end result always and necessarily a state of consciousness. Conscious memory is only a particular type of memory. The same process may terminate in purely unconscious or physiologi- cal effects, or what may be called physiological memory to distinguish it from conscious memory. Along with the revived ideas and their feeling tones there may be a revival of the physiological experi- ences, or processes, which originally accompanied them; such as secretion of sweat, saliva and gastric juice, the contraction and dilatation of the blood vessels, the inhibition or excitation of the heart, lungs and other viscera, the contraction of muscles, etc. These visceral mechanisms, being originally elements in a complex process and accompaniments of the idea, may be reproduced along with the con- scious memory, and even without conscious memory. As this physiological complex is an acquired experi- ence it is entitled to be regarded as memory so far as its reproduction is the end result of the same kind of process or mechanism as that which repro- duces ideas. Then, again, investigations into the subconscious have shown that the original experience may be re- produced subconsciously without rising into aware- ness. The more comprehensive way, then, of looking at memory is to regard it as a process and not simply as an end result. The process, as we shall see, is made up of three factors Registration, Conserva- tion, and Reproduction. Of these the end result is 4 THE UNCONSCIOUS reproduction; conservation being the preservation of that which was registered. This view is far more fruitful, as you will pres- ently see, for memory acquires a deeper significance and will be found to play a fundamental and unsus- pected part in the mechanism of many obscure mental processes. From this point of view, ipon memory, considered as a process, depend the acquired conscious and subconscious habits of mind and body. The process involves unconscious as well as con- scious factors and may be wholly unconscious (sub- conscious). Two of its factors registration and conservation are responsible for the building up of the uncon- scious as the storehouse of the mind and, therefore, primarily for all subconscious processes, other than those which are innate. To it may be referred the direct excitation of many subconscious manifestations of various kinds. Consciously or subconsciously it largely deter- mines our prejudices, our superstitions, our beliefs, our points of view, our attitudes of mind. Upon it to a large degree depend what we call personality and character. It often is the unsuspected and subconscious secret of our judgments, our sentiments, and im- pulses. It is the process which most commonly induces dreams and furnishes the material out of which they are constructed. THEORY OF MEMORY AS A PROCESS 5 It is the basis of many hypnotic phenomena. In the field of pathology, memory, through its perversions, takes part in and helps to determine the form of a variety of disturbances such as ob- sessions, impulsions, tics, habit psychoses and neuroses, many of the manifestations of that great protean psychosis, hysteria, and other common ail- ments which it is the fashion of the day to term neurasthenia and psychasthenia. It is largely re- sponsible for the conscious and subconscious con- flicts which disrupt the human mind and result in various pathological states. Finally, upon the utilization of the processes of memory modern psychotherapeutics, or the educa- tional treatment of disease, is largely based. For many of these reasons an understanding of the mechanism of memory is essential for an under- standing of the subconscious. In short, memory furnishes a standpoint from which we can produc- tively study the normal and abnormal processes of the mind conscious and subconscious. These somewhat dogmatic general statements which I have put before you much after the fashion of the lawyer who presents a general statement of his case in anticipation of the evidence I hope will become clear and their truth evident as we proceed; likewise, their bearing upon the facts of abnormal psychology. To make them clear it will be necessary to explain in some detail the generally accepted theory of memory as a process and to cite the numerous data upon which it rests. 6 THE UNCONSCIOUS There may be, as, indeed, you will find there are, wide differences of opinion as to the exact psycho- logical mechanism by which a memory-process plays its part in the larger processes of mental life, nor- mal and abnormal, such as I have just mentioned, but that the memory-process is a fundamental factor is revealed by whatever method the problems are attacked. A study, therefore, of this funda- mental factor and a determination of its mechanism are a prerequisite for a study of the more complex processes in which it takes part. For this reason I shall begin the study of the Unconscious (sub- conscious), to which I shall ask your attention in these lectures, with a consideration of the processes of memory. If you ask the average person, as I have often done, how or why he remembers he will be puzzled and he is apt to reply, "Why, I just remember," or, ' ' I never thought of that before. ' ' If you push him a bit and ask what becomes of ideas after they have passed out of mind and have given place to other ideas, and how an idea that has passed out of mind, that has gone, disappeared, can be brought back again as memory, he becomes further puzzled. We know that ideas that have passed out of mind may be voluntarily recalled, or reproduced, as memory; we may say that meantime they have become what may be called dormant. But surely something must have happened to enable these conscious ex- periences to be conserved in some way and recalled. Ideas are not material things which, like books, can THEORY OF MEMORY AS A PROCESS 7 be laid away on a shelf to be taken up again when wanted, and yet we can recall, or repro- duce, many ideas when we want them just as we can go to a shelf and take down any book we want. We learn the alphabet and the multiplication table in childhood. During the greater part of our lives the sensory images, auditory language symbols, etc., which may be summarized as ideas representing these educational experiences, are out of our minds and do not form a continuous part of our conscious experiences, but they may be recalled at any moment as memory. In fact, try as hard as we may, we cannot forget our alphabet or multiplication table. Why is this f The older psychology did not bother itself much with these questions which puzzle the average man. It was content for the most part with a descriptive statement of the facts of conscious memory. It did not concern itself with the process by which memory is effected ; nor, so long as psychology dealt only with phases of consciousness, was it of much consequence. It has been only since subconscious processes have loomed large in psychology and have been seen to take part on the one hand in the mechanism of conscious thought and on the other to produce various bodily phenomena, that the process of memory has acquired great practical importance. For it has been seen that in these subconscious processes previous conscious experiences are resur- rected to take part as subconscious memory, conse- 8 THE UNCONSCIOUS quently a conscious experience that has passed out of mind may not only recur again as conscious memory, but may recur subconsciously below the threshold of awareness. The study of subconscious processes therefore necessarily includes the proc- esses of memory. And so it has become a matter of considerable moment to follow the fate of experi- ences after they have passed out of mind with a view to determining the mechanism by which they can be reproduced consciously and subconsciously. More than this it is important that the theory of memory should be removed if possible from the domain of purely speculative psychological con- cepts and placed on a sound basis of observation and experiment like other accepted theories of science. From the point of view of animism, and indeed of dualism, nothing becomes of the ideas that have passed out of mind ; they simply, for the time being, cease to exist. Consciousness changes its form. Nothing is preserved, nothing is stored up. This is still the popular notion according to which a mental experience at any given moment the con- tent of my consciousness, for instance, at this mo- ment as I speak to you is only one of a series of kaleidoscopic changes or phases of my self-con- sciousness. In saying this what is meant plainly must be that the content of consciousness at any given moment is a phase of a continuing psychical something. We may, perhaps, call this my self- consciousness, and say that when I reproduce an THEORY OF MEMORY AS A PROCESS 9 experience as memory I simply bring back (by the power of self-determination) that same previous phase of the psychical something. If I cannot bring it back my failure may be due to a failure of the power of self-determination or and here is a weak point to a failure in the formative cohesion of the elementary ideas of that experience. In this latter alternative no note is taken of a seeming contradic- tion or paradox. If nothing is preserved, if nothing continues to exist, if memory is only one of a series of kaleidoscopic phases of consciousness, how can there be any cohesion or organization within what does not exist? Consciousness according to this no- tion might be likened to the water of a lake in which vortices were constantly being formed, either by the current of inflowing springs from the bottom or the influences of external agencies. One vortex would give place to a succeeding vortex. Memory would be analogous to the reproduction of a previously occurring vortex. When, however, such a notion of memory is ex- amined in the light of all the facts which have to be explained it will be found to be descriptive only of our conscious experiences. It does not explain memory; it does not answer the question of the ordinary man, "How can ideas which have ceased to exist be reproduced again as memory 1 ?" For, putting aside various psychological difficulties such as, How can I determine the reproduction of a former phase of consciousness that is, memory without first remembering what I want to deter- 10 THE UNCONSCIOUS mine?, or, if this be answered, "By the association of phases (ideas)," how can there be any bond of association between an existing idea and one that does not exist?, and, therefore, how can association bring back that which has ceased to exist? putting aside such questions, there are a number of psycho- physiological facts which this conception of memory will be found inadequate to meet. As a matter of fact, investigations into the behavior of mental processes, particularly under artificial and patho- logical conditions, have disclosed certain phenomena which can be adequately explained only on the supposition that ideas as they pass out of mind the mental experiences of the moment leave some- thing behind, some residuum which is preserved, stored up as it were, and which plays a subsequent part in the process of memory. These phenomena seem to require what may be called a psycho-physi- ological theory of memory. Although the theory has long been one of the concepts of normal psychology it can be said to have been satisfactorily validated only by the investigations of recent years in abnormal psychology. The full significance as well as the validity of this theory can be properly estimated only in the light of the facts which have been revealed by modern technical methods of investigation. After all, it is the consequences of a theory which count, and this will be seen to be true particularly as respects memory. The pragmatic point of view of counting the consequences, of determining the dif- THEORY OF MEMORY AS A PROCESS 11 ference that the theory makes in the understanding of the mental processes of normal and abnormal life, reveals the importance to us of validating the theory. The consequences of the psycho-physio- logical theory are so far-reaching, in view of its bearing upon a large number of problems in normal and abnormal psychology, that it is worthy of sus- tained and exhaustive examination. I will, there- fore, briefly resume the various classes of facts which support the theory and which any adequate theory of memory must satisfactorily explain. For, as will appear, besides the common facts of memory pertaining to everyday life, there are a large num- ber of other facts which can be observed only when the mind is dissected, so to speak, by pathological processes, and by the production of artificial condi- tions, and when investigations are carried out by special technic. Irrespective of any theory of ex- planation, a knowledge of these facts is extremely important for an understanding of many phenom- ena in the domain of both normal and abnormal psychology. The meaning of conservation We all know, as an everyday experience of mankind, that at one time we can recall what happened to us at some par- ticular moment in the past, and at another time we cannot. We know that when we have forgotten some experience if we stimulate or refresh our memory, as the lawyers say to us on the witness- gtand, by reference to our notes, appropriately 12 THE UNCONSCIOUS called memoranda, the original experience may come back to mind. Often at one moment we cannot recall a verse, or a name, or a piece of acquired knowledge, while at another time, a little later, we can. We have a feeling, a perhaps justifiable belief, that a desired piece of knowledge is not lost, that it is back somewhere in our minds but we cannot get at it. If, sooner or later, under one circumstance or another, with or without the aid of some kind of stimulus, we can recall the desired knowledge we say it was preserved (or conserved). If we continue, under all circumstances and at all mo- ments, to be unable to recall it we say it is lost, that our memory of it is not conserved. So the notion of conservation of knowledge being something apart from recollection enters even into popular language. What sort of thing conservation is, popular language does not attempt to define. It is clear, however, that we may with propriety speak of the conservation of experiences, using this term in a descriptive sense without forming any definite concept of the nature of conservation. Provision- ally, then, I shall speak of conservation of a given experience in this sense only, meaning that the memory of it is not permanently lost but that under certain particular circumstances we can recall it. Now a large mass of observations demonstrate that there are an enormous number of experiences, belonging to both normar and abnormal mental life, which we are unable to voluntarily recall during any period of our lives, no matter how hard we try, or THEORY OF MEMORY AS A PROCESS 13 what aids to memory we employ. For these ex- periences there is life-long amnesia. Nevertheless, it is easy to demonstrate that, though the personal consciousness of everyday life cannot recall them, they are not lost, properly speaking, but conserved ; for when the personal consciousness has undergone a peculiar change, at moments when certain special alterations have taken place in the conditions of the personal consciousness, at such moments you find that the subject under investigation recalls the apparently lost experiences. These moments are those of hypnosis, abstraction, dreams, and certain pathological states. Again, in certain individuals it is possible by technical devices to awaken sec- ondary mental processes in the form of a subcon- sciousness which may manifest the memories of the forgotten experiences without awareness therefor on the part of the personal consciousness. These manifestations are known as automatic writing and speech. Then, again, by means of certain post- hypnotic phenomena, it is easy to study conserva- tion experimentally. We can make, as you will later see, substantially everything that happened to the subject of the experiment in hypnosis his thoughts, his speech, his actions, for all of which he has complete and irretrievable loss of memory in a waking state we can make memory for all these lost experiences reappear when hypnosis is again induced. Thus we can prove conservation when voluntary memory for experiences is abso- lutely lost. These experiments, among others, as 14 THE UNCONSCIOUS we shall also see, also give an insight into the nature of conservation which is the real problem involved in an investigation into the process of memory. Before undertaking to solve this problem so far as may be done it is well to obtain a full realiza- tion of the extent to which experiences which have been forgotten may be still conserved. I will there- fore, as I promised you, resume the experimental and other evidence supporting this principle, mak- ing use of both personal observations and those of others. NOTE In the following exposition of the evidence for the theory of memory it has been necessary to make use of phenomena subsuming subconscious processes before the subconscious itself has been demon- strated. A few words in explanation of the terms used is therefore desirable to avoid confusing the reader. Dividing as I do the subconscious into the unconscious and the coconscious, the former is either simply a neural disposition, or an active neural process without any quality of consciousness; the latter is an actual subconscious idea or a process of thought of which, never- theless, we are not aware. An unconscious and a coconscious process are both, therefore, only particular types of a subconscious process. I might have used the single term subconscious througliout the first seven lectures, but in that case, though temporarily less confusing, the data necessary for the appreciation of the division of the sub- conscious into two orders would not have been at hand. Typical phenomena having been described as unconscious or coconscious (in- stead of simply subconscious), the reader will have already become familiar with examples of each type and be thus prepared for the final discussion in Lecture Fill. PROVISIONALLY, these three terms may be regarded as synonyms. To indicate the synonym, the term "subconscious" has often been added in parenthesis in the text to one or other of the subdivisional terms, and vice versa. LECTURE H CONSERVATION OF FORGOTTEN EXPERIENCES OF NORMAL, ARTIFICIAL, AND PATHOLOGICAL LIFE I. Normal Life Evidence obtained by the method of automatic writing. If we take a suitable subject, one in whom "automa- tic writing" has been developed, and study the content of the script, we may find that to a large extent it contains references to, i. e., memories of, experiences which have long been forgotten by the subject and which cannot even by the stimulus of memoranda be voluntarily recalled. * Automatic writing is script which has been produced uncon- sciously or involuntarily, although the writer is in an alert state, whether it be the normal waking state or hypnosis. The hand writes, though the subject does not consciously direct it. Ordinarily, though not always, the subject is entirely unaware of what the hand is writ- ing, and often the writing is obtaiaed better if the attention is di- verted and directed toward other matters. The first knowledge then obtained by the subject of what has been written, or that the hand has written at all, is on reading the script. Some persons can culti- vate the art of this kind of writing. Mrs. Verrall and Mrs. Holland, for example, deliberately educated themselves to write automatically, and each published a volume of her records. In other normal people automatic writing seems to develop accidentally or under special cir- cumstances. In certain types of hysteria it is very easily obtained. " Planchette, " which many years ago was in vogue as a parlor game, was only a particular device to effect automatic writing. 15 16 THE UNCONSCIOUS These experiences may be actions performed even as far back as childhood, or passages read in books, or fragments of conversation, etc. Thus B. C. A., who suffers from an intense fear or phobia of cats, particularly white cats, can recall no experience in her life which could have given rise to it. Yet when automatic writing is resorted to the hand writes a detailed account of a fright into which she was thrown, when she was only five or six years of age, by a white kitten which had a fit while she was playing with it. The writing also describes in minute detail the furnishings of the room where the episode occurred, the pattern of the carpet, the decorative designs of the window shades, the fur- niture, etc. As this observation is typical of many others, it may be well to dwell upon it long enough to describe it in some detail for the benefit of those who are not familiar with this class of phenomena. After it had been determined, by a searching ex- amination, that B. C. A. could not recall any ex- perience that might throw light upon her phobia, an attempt was made to recover a possible memory in hypnosis. As is well known, the memory often broadens in hypnosis and events which are forgot- ten when " awake" may be recovered. In this in- stance the subject was put into two different hyp- notic states, but without success. This, again, is a matter of some importance for the principle of conservation. Different hypnotic states in the same individual may be distinguished in that each, among other characteristics, may have different and inde- FORGOTTEN EXPERIENCES 17 pendent systems of memories, as we shall see later. The memories which belong to one state cannot be recalled in another. Hence the fact that a memory cannot be recovered in one state is not proof that it is not conserved, nor is a failure to recover the memory of an episode in all states of hypnosis evi- dence of failure of conservation, any more than is the failure to recover a memory in the waking state at any given moment. In the experiment with B. C. A., after failing to awaken a possible memory in either state of hyp- nosis, a pencil was put in her hand while she was still hypnotized. The hand then wrote automatic- ally, without the knowledge of the hypnotized sub- ject, the following account of this childhood episode that I have just mentioned:* "I think I know about the cats. I can remember myself, a little child, playing on the floor with a kitten, and it began to run about the room and had a fit, I think, and it jumped on me, and I was alone, and I screamed and cried and called my mother, but no one came, and I was very much frightened. I do not believe I ever told anyone. It was a white * In this particular experiment, when the hand wrote ' ' automat- ically, " the second hypnotic consciousness vanished and the subject went into a trance state, or what is equivalent to a third hypnotic state. There was no consciousness present, excepting that which was associated with the writing hand. At other times, in experiments of this class with this same subject, the hypnotic or the waking con- sciousness, as the case might be, persisted alert while the hand wrote. For the purpose of the experiment in recovering memories this change in the psychological condition is not of importance, the principle re- mains the same. 18 THE UNCONSCIOUS kitten. It ran out of the room and after a bit I went on playing. ' ' To test the extent of the conserved memories still further the hand was asked to describe the furnish- ings of the room and the plan of the house. It wrote : "There were two windows on the side of the room. The shades were gray, I think, with a border of grapes, or something of that color. The carpet was green or gray with green figures. There was a large old-fashioned sofa between one window and the door which led into the dining-room. A book- case and desk-combination, you know. There was a mantle, I think, between the windows. It was the ground floor." This childhood episode and the furnishings of the room were completely forgotten by B. C. A. in the sense that they could not be voluntarily recalled. Even after reading the script she could not remem- ber them. She had not seen the room since she was six years of age, the family having removed at that time from the town in which the incident took place. As to the accuracy of the "automatic" account and the possibility of fabrication, the description of the room has been corroborated by the independent and written testimony of an older member of the family. It was not possible to confirm the incident of the kitten as there were no witnesses. This portion of the account, therefore, cannot be proved not to be a fabrication, but I have never known a fabricated statement to be made in this subject's automatic FORGOTTEN EXPERIENCES 19 script, and I have obtained from her a large number of statements of different kinds in the course of several years' observation. However that may be, the point is not essential, for the minute description, by a special technic, of the furnishings of a room which had not been seen since childhood, a matter of some thirty-five years, and which were totally forgotten, is a sufficient demonstration of the principle of conservation of conscious experiences that cannot be voluntarily recalled. The reproduction of the conscious experi- ence by automatic writing was, of course, an act of memory effected by a special device, and this fact compels us to postulate the conservation of the experience during this long period of time, notwith- standing that the experience could not be recalled voluntarily. Although the conserved experience could not be awakened into memory by voluntary processes of the personal consciousness it could be so awakened by an artificial stimulus under artifi- cial conditions. An observation like this, dealing with the con- servation of long forgotten childhood or other ex- periences, is not unique. Quite a collection of recorded cases might be cited. Mr. C. Lowe Dickinson has put on record * one of a young woman (Miss C.), who, in an hypnotic trance, nar- rated a dream-like fabrication of a highly imagina- * Journal of the S. P. R., July, 1906. A fuller account of this case was later published in the same journal, August, 1911. 20 THE UNCONSCIOUS tive character. On one occasion, through the imag- inary intermediation of the spirit of a fictitious person, who was supposed to have lived in the time of Richard II, she gave a great many details about the Earl and Countess of Salisbury, "and other personages of the time, and about the manners and customs of that age. The personages referred to, the details given in connection with them, and especially the genealogical data, were found on ex- amination to be correct, although many of them were such as apparently it would not have been easy to ascertain without considerable historical research. ' ' Miss C. after coming out of the hypnotic trance was in entire ignorance of how she could have obtained this knowledge and could not recall ever having read any book which contained the information she had given. Through automatic writing, however, it was discovered that it was to be found in a book called The Countess Maud, by E. Holt. It then appeared and this is the point of interest bearing on the conservation of forgotten knowledge that this book had been read to her by her aunt fourteen years previously, when she was a child about eleven years old. Both ladies had so completely forgotten its contents that they could not recall even the period with which it dealt. Here were conscious experiences of childhood which, if voluntary recollection were to be made use of as a test, would be rightly said to have been extin- guished, but that they had only lain fallow, con- FORGOTTEN EXPERIENCES 21 served in some unconscious fashion, was shown by their reproduction in the hypnotic trance.* In this connection I may instance the case of Mrs. C. D., who suffers from a fixed fear of fainting. She cannot recall, even after two prolonged search- ing examinations, the first occasion when this fear developed, or why she has it, and is, therefore, ignorant of its genesis. Yet put into abstraction or light hypnosis she recalls vividly its first occurrence as the effect of an emotional scene of twenty years ago. The details of its psychological content come clearly into consciousness, and its meaning, as a fear of death, is remembered as a part of the ori- ginal episode. That the fixed idea is a recurrence or partial memory of the original complex becomes logically plain and is recognized as such. Instances of the reproduction in automatic script of forgotten passages from books are to be found in Mrs. Verrall'sf elaborate records of her own automatic writings. Investigation showed that numerous pieces of English, Latin, and Greek script * A remark made by the subject in the trance state, though passed over in the report as apparently inconsequential, has really much meaning when interpreted through that conception of the uncon- scious memory process which will be developed in succeeding chap- ters. The subject, while in the trance, claimed to be in a mental world wherein "is to be found, it is said, not only everything that has ever happened or will happen, but all thoughts, dreams, and im- agination. " In other words, in that psychical condition into which she passed, all the conserved conscious experiences of her life could be awakened into memory. f Proceedings of the S. P. B., October, 1906, Chap. XII, 22 THE UNCONSCIOUS were not original compositions but only forgotten passages from authors previously read. Mrs. Holland's script records, as investigation seemed to show, the exact words expressing a per- sonal sentiment contained in a letter written to her twenty years before and long forgotten. The letter proving this was accidentally discovered.* The following instance of a forgotten experience is, in itself, common enough with everybody, but its recovery by automatic writing illustrates how con- servation of the thousand and one simply forgotten acts of everyday life may still persist. It forces, too, a realization of the reason why it is possible that though an act may be forgotten at any given moment it may later at any time flash into the mind. It is still conserved. B. C. A. had been vainly hunting for a bunch of keys which she had not seen or thought of for four months, having been in Europe. One day, soon after her return, while writing a letter to her son she was interrupted by her hand automatically and spontaneously writing the desired information. * In the automatic script, which purported to be a spiritistic mes- sage from a dead friend named Annette, occurred the enigmatical sentence: "Tell her this comes from the friend who loved cradles and cradled things. ' ' The meaning of this was revealed by the above-mentioned letter to Mrs. Holland, written twenty years pre- viously. It was from a friend of Annette 's, and quoted an extract from Annette's will, which ran, "because I love cradles and cradled things. ' ' When Mrs. Holland was tearing up some old letters she came across this one. ("On the automatic writing of Mrs. Holland," by Miss Alice Johnson: Proceedings of the S. P. E., June, 1908, pp. 288, 289.) FORGOTTEN EXPERIENCES 23 The letter to her son began as follows: "October 30, 19 . Dear Boy: I cannot find those keys- have hunted everywhere" . . . [Here the hand be- gan to write the following, automatically.] "0, I know take a pencil" [Here she did as she was bidden] "you put those keys in the little box where X's watch is." In explanation B. C. A. sent me the following letter : * ' The keys were found in the box mentioned. I had hunted for them ever since coming home, October 4th. One key belonged to my box in the safety deposit vault and I had felt very troubled and anxious at not being able to find them. I have no recollection now of putting them where I found them." [Nor was recollection subsequently recov- ered.] I could give from my own observation if it were necessary as many instances as could be desired of "automatic" reproductions of forgotten experi- ences of one kind or another the truth of which could be verified by notebook records or other evi- dence. By a forgotten experience of course is meant something more than what cannot for the moment be voluntarily recalled. I mean something that cannot be remembered at any moment nor under any conditions, even after the memory has been prodded by the reproduction in the script something that is apparently absolutely forgotten. The experience may not only be of a trivial nature but something that happened long in the past and of the kind that is ordinarily absolutely forgotten, I 24 THE UNCONSCIOUS have often invoked the automatic writing (memor- ies) of the subject to recover data elicited in the past in psychological examinations but which both I and the subject had forgotten. Reference to notes always verified the automatic memories. The records of automatic writing to be found in the literature are rich in reproductions showing con- servation of forgotten experiences. In fact, given a good subject who can write automatically it is easy to obtain experimentally evidence of this kind at will. Evidence from abstraction One of the most striking of artificial memory performances is the recovery of the details of inconsequential experiences of everyday life by inducing simple states of abstrac- tion in normal people. It is often astonishing to see with what detail these experiences are conserved. A person may remember any given experience in a general way, such as what he does during the course of the day, but the minute details of the day he ordinarily forgets. Now, if he allows himself to fall into a passive state of abstraction, simply concentrating his attention upon a particu- lar past moment, and gives free rein to all the asso- ciative memories belonging to that moment that float into his mind, at the same time taking care to forego all critical reflection upon them, it will be found that the number of details that will be re- called will be enormously greater than can be recovered by voluntary memory. Memories of the FORGOTTEN EXPERIENCES 25 details of each successive moment follow one an- other in continuous succession. This method re- quires some art and practice to be successfully carried out. In the state of abstraction attention to the environment must be completely excluded and concentrated upon the past moments which it is desired to recall. For instance, a young woman, a university student, had lost some money several days before the experiment and desired to learn what had become of it. She remembered, in a gen- eral way, that she had gone to the bank that day, had cashed some checks, made some purchases in the shops of the town, returned to the university, attended lectures, etc., and later had missed the money from her purse. Her memory was about as extensive as that of the ordinary person would be for similar events after the lapse of several days. I put her into a state of abstraction and evoked her memories in the way I have just described. The minuteness and vividness with which the details of each successive act in the day's experiences were recovered were remarkable, and, to the subject, quite astonishing. As the memories arose she recognized them as being accurate, for she then remembered the events as having occurred, just as one remem- bers any occurrence.* In abstraction, she remem- bered with great vividness every detail at the bank- * It would have required a stenographer, whom I did not have, to record fully all these recovered memories. They would fill several printed pages, and I can give only a general resum6 of them. Some weeks later the experiment was repeated and a record taken as fully as possible in long hand. 26 THE UNCONSCIOUS teller's window, where she placed her gloves, purse, and umbrella, the checks, the money, etc. ; then there came memories of seating herself at a table in the bank, of placing her umbrella here, her purse there, etc. ; of writing a letter, and doing other things ; of absent-mindedly forgetting her gloves and leaving them on the table ;* of going to a certain shop where, after looking at various articles and thinking cer- tain thoughts and making certain remarks, she finally made certain purchases, giving a certain piece of money and receiving the change in coin of certain denominations; of seeing in her purse the exact denominations of the coins (ten and five- dollar gold pieces and the pieces of subsidiary coin- age) which remained; then of going to another shop and similar experiences. Then of numerous details which she had forgotten ; of other later incidents in- cluding lectures, exercising in the gymnasium, etc. Through it all ran the successive fortunes of her purse until the moment came when, looking into it, she found one of the five-dollar gold pieces gone. It became pretty clear that the piece had disap- peared at a moment when the purse was out of her possession, a fact which she had not previously re- membered but had believed the contrary. The hundred and one previously forgotten details which surged into her mind as vivid conscious recollec- tions would take too long to narrate. * Later in the day she discovered the loss of her gloves and, not remembering where she had left them, was obliged to retrace her steps in search of them. FORGOTTEN EXPERIENCES 27 (I have made quite a number of experiments of this kind with similar results. That the memories are not fabrications is shown by the fact that, as they arise, they become recollections in the sense that the subject can then consciously recall the events and place them in time and space as one does in ordinary memory, and particularly by the fact that many of them are often capable of confirma- tion. I would here point out that the recovery of for- gotten experiences by the method of abstraction differs in one important psychological respect from their recovery by automatic writing. In the former case the recalled experiences being brought back by associative memories enter into the associations and become true conscious recollections, like any other recollections, while in automatic writing the memories are reproduced in script without enter- ing the personal consciousness at all and while the subject is still in ignorance. Often even after read- ing the script his memory still remains a blank. It is much as if one's ideas had been preserved on a phonographic record and later reproduced without awakening a memory of their original occurrence.* The significance of this difference for the theory * Of course the memories recovered by either method may be fabrications as with ordinary voluntary memory, and the automatic script may stimulate the conscious memory to recollect the expe- riences in question. Nevertheless, while the memories are being re- corded by the script, no ' ' conscious ' ' memory is present with sub- jects who are unaware of what the hand is writing. 28 THE UNCONSCIOUS of conservation I will point out later after we have considered some other modes of reproduction.) Among the conserved forgotten experiences are often to be found fleeting thoughts, ideas, and per- ceptions, so insignificant and trifling that it would not be expected that they would be remembered. Some of them may have entered only the margin or fringe of the content of consciousness, and, there- fore, the subject was only dimly aware of them. Some may have been so far outside the focus of awareness that there was no awareness of them at all, i. e., they were subconscious. Instructive ex- amples of such conserved experiences may be found in persons who suffer from attacks of phobia, i. e., obsessions. The experiences to which I refer occur immediately before and during the attacks. After the attack the ideas of these periods are usually largely or wholly forgotten, particularly the ideas which were in the fringe of consciousness and the idea which, according to my observation, was the exciting cause of the attack. By the method of abstraction I have been able to recover the content of consciousness during the periods in question, in- cluding the fringe of consciousness, and thus dis- cover the nature of the fear of which the patient was unaware because the idea was in the fringe. Mrs. C. D., whom I have mentioned as having suffered intensely from attacks of fear, and Miss F. E., who is similarly afflicted with such attacks accompanied by the feeling of unreality, are in- stances in point. As is well known such attacks FORGOTTEN EXPERIENCES 29 come on suddenly in the midst of mental tranquil- lity, often without apparent cause so far as the pa- tient can discover. While in the state of abstraction the thoughts, perceptions, and acts of the period just preceding and during the attack, as they suc- cessively occurred, could be evoked in these sub- jects in great detail and with striking vividness. The recovery of these memories has been always a surprise to the patient who, a moment before, had been utterly unable to recall them, and had declared the attack had developed without cause. In the case of Mrs. C. D. it was discovered in this way the real fear was of fainting and death, and in that of Miss F. E. of insanity. These ideas having been in the fringe of consciousness, or background of the mind, the subjects were at the time scarcely aware of them and, therefore, were ignorant of the true nature of their phobias, notwithstanding the over- whelming intensity of the attacks. Among the memories recovered in these and other cases I have always been able to find one of a thought or of a sensory stimulus from the environment which im- mediately preceded and which through association occasioned the attack. When this particular mem- ory was recovered the patient, who had declared that the attack had developed without cause, at once recognized the original idea which was the cause of the attack, just as one recognizes the idea which causes one to blush. The idea sometimes has been a thought suggested by a casual and apparently in- significant word in a sentence occurring in a con- 30 THE UNCONSCIOUS versation on indifferent matters, or by a dimly conscious perception of the environment, sometimes an idea occurring as a secondary train of thought perhaps bearing upon some future course of action, and so on. As instances of such dimly-conscious perceptions of the environment which I have found I may men- tion a gateway through which the subject was passing, or a bridge about to be crossed; these particular points in the environment being places where previous attacks had occurred. The percep- tions which precipitated the attack may have been entirely subconscious and yet may be brought back to memory. With the pathogenesis of the attacks we are not now directly concerned. The point of interest for us lies in the fact that such forgotten casual ideas and perceptions, some of which had been actually subconscious and some had only en- tered the margin of the focus of attention may, not- withstanding the amnesia, be conserved; and the same is true of any succession of trivial ideas occur- ring at an inconsequential moment in a person 's life. However that may be, if you will try to recall in exact detail the thoughts and feelings which suc- cessively passed through your mind at any given moment say three or four weeks ago or even days ago and their accompanying acts, and then (if you can do this, which I very much doubt) try to give them in their original sequence, I think you will realize the force of these observations and appre- ciate the significance of the conservation of such FORGOTTEN EXPERIENCES 31 minute experiences and of their reproduction in abstraction. Evidence furnished by the method of hypnosis. It is al- most common knowledge that when a person is hypnotized whether lightly or deeply he may be able to remember once well-known events of his conscious life which he has totally forgotten in the full w^aking state. It is not so generally known that he may also be able to recall conscious events of which he was never consciously aware, that is to say, experiences which were entirely subconscious. The same is true, of course, of forgotten experi- ences which originally had entered only the margin of the content of consciousness and of which he was dimly aware. Among the experiences thus recalled may be perceptions of minute details of the environ- ment which escape the attentive notice of the in- dividual, or they may be thoughts which were in the background of the mind and, therefore, never in the full light of attention. You must not fall into the common error of believing every hypnotized per- son can do this, or that any person can do it in any state of hypnosis. There are various "de- grees" or states of hypnosis representing different conditions of dissociation and synthesis. One per- son may successively be put into several different states; many persons can be put into only one, but the degree of dissociation and capacity for syn- thesis in each state and in every person varies very much, and, indeed, according to the technical devices 32 THE UNCONSCIOUS employed. Each state is apt to exhibit different systems of memories, that is, to synthesize (recall) past conserved experiences in a different degree. What cannot be recalled in one state may be in another. We may say as a general principle that theoretically any experience that has been con- served can be recalled in some state, and, con- versely, there is theoretically some state in which any conserved experience can be recalled. Practi- cally, of course, we can never induce a state which synthesizes all conserved experiences, nor always one in which any given experience is synthesized. I shall later, in connection with particular types of conscious states, give examples of hypnotic mem- ories showing conservation of such experiences as I have just mentioned. The point you will not lose sight of is that we are concerned with hypnotic phenomena only so far as they may be evidence of the conservation of forgotten experiences. There is a class of hypnotic memory phenomena which acquire additional importance because of the bearing they have upon the psycho-genesis of cer- tain pathological conditions. They show the con- servation of the details of an episode in their original chronological order with an exactness that is beyond the powers of voluntary memory to repro- duce. These phenomena consist of the realistic re- production of certain emotional episodes which as a whole may or may not be forgotten. The repro- duction is realistic in the sense that the episodes FORGOTTEN EXPERIENCES 33 are acted over again by the individual as if once more he were actually experiencing them. Appar- ently every detail is reproduced, including the emotion with its facial expressions and its other physiological manifestations, and pathological dis- turbances like pain, paralysis, anesthesia, move- ments, etc. I will cite the following three examples : M 1, a Eussian, living in this country, suffers from psycholeptic attacks dating from an episode which occurred seven years previously and which he has completely forgotten. At that time he was living in Russia. It happened that after returning from a ball he was sent back late at night by his employer, a woman, to look for a ring which she had lost in the ballroom. His way led over a lonely road by a graveyard. As he was passing this place he heard footsteps behind him and became fright- ened. Overcome with terror he fell, partially un- conscious, and his whole right side became affected with spasms and paralysis. He was picked up in this condition and taken to a hospital. Each year since that time he has had recurring attacks of spasms and paralysis.* In hypnosis he remembers and relates a dream. This dream is one which recurs periodically but is forgotten after waking from sleep. This is the dream : He is back in his native land ; it is the night of the ball; he sees his employer with outstretched hand commanding him to go search for the ring. * Sidis, Prince, and Linenthal : A contribution to the Pathology of Hysteria, Boston Medical and Surgical Journal, June 23, 1904. 34 THE UNCONSCIOUS Once more he makes his way along the lonely road; he hears footsteps; he becomes frightened, falls, and then awakes, with entire oblivion for the dream, to find his right side paralyzed and in spasms. The following experiment is now made. By sug- gestion in hypnosis he is made to believe that he is fifteen years of age. As a consequence in his hypnotic dream he is once more living in Russia before he had learned English. It is now found that he has spontaneously lost all knowledge of the English language and can speak only Eussian. He is told it is the night of the ball and, as in a dream, he is carried successively through the different events of that night. Finally he returns in search of the ring, passes again over the lonely road, hears the footsteps and becomes frightened. At this point his face is suddenly contorted with an expres- sion of fright, the whole right side becomes para- lyzed and anesthetic, and the muscles of face, arm, and leg affected with clonic spasms. At the same time he moans with pain which he experiences in his side, which he hurt when he fell. Though con- sciousness is confused he answers questions and describes the pain which he feels. On being awak- ened all passes off. Mrs. W. on her return to Boston after an ab- sence in Europe happened to pass by a certain house on her way to her hotel; the house (a private hospital) was one with which she had very distress- ing associations. On leaving the steamer she took a street car which she left a block distant from the FORGOTTEN EXPERIENCES 35 hotel. She walked this distance and as she passed the house she was seized with a sudden attack of fear, dizziness, palpitation, etc. Although it is beside the point I may say that she had not noticed the locality and did not consciously recognize the house until the attack developed. The attack was, therefore, induced by a subconscious perception.* She recalls the incident and describes the attack, remembers that it occurred at this particular spot, but without further detail. Now in hypnosis she is taken back to the day of her arrival on the steamship. In imagination, as in a sort of dream, she is living over again that day ; she disembarks from the ship, enters the street car in which she rides a certain distance ; she leaves the car at the point nearest her destination and pro- ceeds to walk the remainder of the distance; sud- denly her face exhibits the liveliest emotion; she becomes strongly agitated and her respiration is short and quick ; her head and eyes turn toward the left and upward, as if in search of a cause, and she exclaims, "Yes, that's it, that's it," as she recognizes in imagination the house which had been the scene of her previous distress. Then the at- tack subsides as she passes by, continuing her way toward her hotel. Mrs. E. B. suffers from traumatic hysteria as the * The Dissociation of a Personality, by Morton Prince. (New York; Longmans, Green & Co., 1906.) P. 77. Hereafter, when this work is referred to, the title will be indicated simply by ' ' The Dis- sociation. ' ' 36 THE UNCONSCIOUS result of a slight but emotional accident a fall when alighting from a railway train. The accident resulted in a sprained shoulder and neuritis of the arm. She fully remembers the accident and de- scribes it as any one might. When put into hypnosis, however, the memory assumes a different character. She is taken back in imagination to the scene of the accident. Once more the train is entering the station; she leaves the car, steps from the platform upon a truck ; then, unawares, steps off the truck and falls to the ground. As she falls her face suddenly becomes distorted with fear; tears stream down her cheeks, which become suffused; her heart palpitates; she suffers again acute pain in her arm, and so on. Her physical and mental anguish is painful to look upon. Though I try to persuade her that she is not hurt and that the accident is a delusion my effort is not very successful. In this experiment, as in the others, there is sub- stantially a reproduction in all its details of the content of consciousness which obtained at the time of the accident, and also of the emotion and its phys- iological manifestations all were faithfully con- served. Further, each event follows in the same chronological sequence as in the original experience. But in these observations the reproduction differs somewhat from that of ordinary memory. It is in the form of a dream, hypnotic or normal, and the subject goes back to the time of the experience, which he thinks is the present, and actually lives FORGOTTEN EXPERIENCES 37 over again the original episode. Unlike the condi- tions of ordinary memory the whole content of his consciousness is practically limited to that which originally was present, all else, the present and the intervening past, being dissociated and excluded. The original psychological processes and their psycho-physiological accompaniments (pain, paral- ysis, anesthesia, spasms, etc.) repeat themselves as if the present were the past. Plainly, for such a reproduction, the original episode must have left conserved dispositions of some kind which when excited were capable of reenacting the episode in all its psycho-physiological details. From a con- sideration of such phenomena it is easy to under- stand how certain psycho-neuroses may be properly regarded as memories of certain past experiences. The experiences are conserved and under certain conditions reproduced from time to time. I may cite one other experiment dealing with the conservation of the details of a day's experiences after the lapse of several months. The subject was a little girl who suffered from hysterical tics. Hop- ing to discover the exciting cause of her nervous disturbance, I put her into deep hypnosis, and evoked the memories of the events of the day on which her disease developed, about six months pre- viously. It was astonishing to hear her recall a continuous series of precise thoughts and acts, many of them trivial, of the kind that would be transient and forgotten by anybody. She began 38 THE UNCONSCIOUS with the events of the early morning, giving her own thoughts and acts; the remarks of her father and mother, describing exactly the location in the house at the time of each member of the family ; her arrival at school; the several lessons of the day; the remarks of the teacher; the happenings during recess ; her final entry into the laboratory ; and the sudden onset of the tic. Everything was given in chronological order. The memories were vivid and, as they came up into her mind, were recognized as true recollections.* All this was forgotten when she was awake, that is to say, although conserved, it could not be reproduced. There was no way, of course, of determining the accuracy of these mem- ories and, therefore, their correctness lacks scien- tific proof. On the other hand, the facts, which are in entire correspondence with similar results ob- tained under conditions where confirmation is possi- ble, have value as cumulative evidence.f It is not difficult to arrange experiments which will test the accuracy with which the minute details of experiences may be conserved when reproduction * Undoubtedly much was forgotten and, therefore, there must have been hiatuses of which she was not aware; but the remarkable thing is that not only so much, but so much that was inconsequential and evanescent was recalled. If additional technical methods had been employed probably more memories could have been recalled. f The objection will probably be made that the memories and statements of hypnotized persons are unreliable on several grounds, chiefly suggestibility, liability to illusions and, in some cases, ten- dency to fabrications. This criticism is more likely to come from those who have had a special rather than a wide experience with hypnotism. FORGOTTEN EXPERIENCES 39 is at fault. A simple test is to have a suitable sub- ject endeavor to repeat verbatim the contents of a letter written by him at some preceding time one week, two weeks, a month, or more. Few people, of course, can do this. If, now, the subject is a suit- able one for the abstraction or hypnotic method it may be that he will be able to reproduce by one or the other method the test letter, word for word; a comparison of the reproduction with the letter will, of course, determine the accuracy of the memory. In such an experiment I have succeeded in getting two subjects, Miss B.* and B. C. A., to repeat ver- batim the contents of fairly long letters, and this even, on certain occasions, when, on account of the subject being a dissociated personality, there was no recollection of the letter at all, not even that it had been written. Such minute reproduction affords further evidence that the conservation of experiences may be much more complete and exact than ordinary conscious memory would lead us to suppose. Evidence from hallucinatory phenomena. I may men- tion one more example of conservation of a forgot- ten experience of everyday life as it is an example or mode of reproduction which differs in certain im- portant respects both from that of ordinary memory and that observed under the artificial * Miss B., in these pages, always refers to Miss Beauchamp, an account of whose case is given in ' ' The Dissociation. ' ' In this connection cf. pp. 501, 81 and 238 of that work. 40 THE UNCONSCIOUS methods thus far described. This mode is that of a visual or an auditory hallucination which may be an exact reproduction in vividness and detail of the original experience. It is a type of a certain class of memory phenomena. One of my subjects, while in a condition of considerable stress of mind owing to the recurrence of the anniversary of her wedding-day, had a vision of her deceased husband, who addressed to her a certain consoling message. It afterwards transpired that this message was an actual reproduction of the words which a friend, in the course of a conversation some months previ- ously, had quoted to her as the words of her own husband just before his death. In the vision the words were put into the mouth of another person, the subject's husband, and were actually heard as an hallucination. Under the peculiar circumstances of their occurrence, however, these words awakened no sense of familiarity; nor did she recognize the source of the words until the automatic writing, which I later obtained, described the circumstances and details of the original episode. Then the ori- ginal experience came back vividly to memory. On the other hand, the "automatic writing" not only remembered the experience but recognized the con- nection between it and the hallucination. (The truth of the writing is corroborated by the written testimony of the other party to the conversation.) Although such types of hallucinatory memories are not actual reproductions of an experience but rather translated representations, yet they show FORGOTTEN EXPERIENCES 41 the experience must have been conserved in order to have determined the representation. The actual experience, as we shall see later, is translated into a visual or auditory form which pictures or verb- ally expresses it, as the case may be. This type of hallucination is common. That which is translated may be previous thoughts, or perceptions received through another sense. Thus Mrs. Holland records a visual hallucination which pictured a verbal de- scription previously narrated to her by a friend, but forgotten. The hallucination included "the fig- ure of a very tall thin man, dressed in gray, stand- ing with his back to the fire. He had a long face, I think a mustache certainly no beard and sug- gested young middle age." ... On a second occa- sion "the tall figure in gray was lying on the bed in a very flung-down, slack- join ted attitude. The face was turned from me, the right arm hanging back across the body which lay on the left side. I started violently and my foot seemed to strike an empty bottle on the floor. ' ' There is very little doubt that these visions of Mrs. Holland's represented Mr. Gurney, who had died from an accidental dose of chloroform. Mrs. Holland "took very little interest" in Mr. Gurney, hence she had entirely forgotten that the main facts of his death had been told to her a few months pre- viously by the narrator, Miss Alice Johnson.* In an hallucination of this sort we have a dra- matic pictorial representation of previous though * Proceedings of the S. P. R., June, 1908. 42 THE UNCONSCIOUS forgotten knowledge which must have determined it. In order to have determined the hallucination the knowledge must have been conserved somehow. I have frequently observed a similar reproduction of a forgotten experience, which was not visual, through translation into a newly created visual representation in the form of an artificial hallucina- tion. The following is of this kind : Miss B., look- ing into a crystal,* saw a scene laid in a wood near a lake, etc. Several figures appeared in this scene, which was that of a murder. Although she had no recollection of anything that could have given rise to the hallucination, investigation showed that the original experience was to be found in one of Marie Correlli's novels which she had read but forgotten. The vision was a correct representation of the scene as described in the book. In suitable subjects almost any past experience, whether forgotten or not, can be reproduced in this way if conserved, and observation shows that the number which are conserved is enormous. I shall * Crystal or artificial visions are hallucinatory phenomena which, like automatic writing, can be cultivated by some people. The com- mon technic is to have a person look into a crystal, at the same time concentrating the mind, or putting himself into a state of abstrac- tion. Under these conditions the subject sees a vision, i. e., has a visual hallucination. The vision may be of some person or place, or may represent a scene which may be enacted. Because of the use of a crystal such hallucinations are called ' ' crystal visions, ' ' but a crystal is not requisite; any reflecting surface may be sufficient, or even the concentration of the attention. The crystal or other ob- ject used of course acts only by aiding the concentration of atten- tion and by force of suggestion. The subconscious is tapped. FORGOTTEN EXPERIENCES 43 have occasion to cite further examples in other con- nections. The phenomenon of translation we shall find when we come to study it, as we shall do in another lecture, throws light upon the nature of conservation for here we are dealing with some- thing more than simple reproduction; what is con- served becomes elaborated into a new composition. Evidence obtained from dreams. Another not uncom- mon mode in which forgotten experiences are re- covered is through dreams. The content of the dream may, as Freud has shown, be a cryptic and symbolical expression or representation of the ex- perience,* or a visualized representation or obvious symbolism, much as a painted picture may be a symbolized expression of an idea,t or it may be a realistic reproduction in the sense that the sub- ject lives over again the actual experience. A relative of mine gave me a very accurate descrip- tion of a person whom she had never seen from a dream in which he appeared. After describing his hair, eyes, contour of face, mouth, etc., she ended with the words, "He looks like a cross between a Scotchman and an Irishman." After she had most positively insisted that she had never seen this person or heard him described against my pro- test to the contrary I reminded her that I had myself described him to her only a few days before * Freud: Traumdeutung, 2 aufl. 1909. f Morton Prince : The Mechanism and Interpretation of Dreams. The Journal of Abnormal Psychology, October- November, 1910. 44 Tffi2 UNCONSCIOUS in the identical words, ending my description with the remark, "He looks like a cross between a Scotchman and an Irishman. ' ' Even then she could not recall the fact. Von Bechterew has recorded the case of a man who frequently after hearing an opera dreamed the whole opera through.* One sub- ject of mine frequently dreamed over again in very minute detail, after an interval of eight or nine months, the scenes attending the deathbed of a relative. Indeed, in the dream she realistically lived them again in a fashion similar to that of hypnotic dreams such as I have related. Although she had not forgotten these scenes it is highly im- probable that she could have voluntarily recalled them, particularly after the lapse of so long a time, without the aid of the dream, so rich was it in detail, with each event in its chronological order. Dream reproductions, whether in a symbolic form or not, are too common to need further state- ment. I would merely point out that the frequency with which childhood's experiences occur in dreams is further evidence of the conservation of these early experiences. The symbolic dream, cryptic or obvious, deserves, however, special consideration because of the data it offers to the problem of the nature of conservation which we shall later study. In this type of dream, if the fundamental principle of the theory of Freud is correct, the content is a * Zentralblatt f iir Nervenheilkunde und Psychiatric ; 1909, Heft 12. FORGOTTEN EXPERIENCES 45 symbolical continuation in some form of an antece- dent thought (experience) of the dreamer.* When this thought, which may be forgotten, is recovered the symbolic character of the dream, in many cases, is recognized beyond reasonable doubt.f If this principle is well established, and nearly all investi- gators are in accord on this point, though we need not always accept the given interpretation of in- dividual dreams if the principle is sound, then it follows that symbolism includes memory of the ori- ginal experience which must be conserved. So that even this type of dream offers evidence of conserva- tion of experiences for which there may be total loss of memory (amnesia). Before closing this lecture I will return to the point which I temporarily passed by, namely, the significance of the difference in the form of repro- duction according as whether it is by automatic writing or through associative memories in abstrac- tion. In the latter case, as we have seen, the mem- ories are identical in form and principle with those of everyday life. They enter the personal con- sciousness and become conscious memories in the sense that the individual personally remembers the experience in question. Abstraction may be re- garded simply as a favorable condition or moment * According to Freud and his school it is always the imaginary fulfilment of a suppressed wish, almost always sexual. For our pur- poses it is not necessary to inquire into the correctness of this in- terpretation or the details of the Freudian theory. f For an example, see p. 98. 46 THE UNCONSCIOUS when the subject remembers what he had at another previous moment forgotten. We have seen also that the same thing is true of remembering in hypnosis (excepting those special realistic repro- ductions when the subject enters a dream-like or somnambulistic state and lives over again the past experience in question). In automatic writing, on the other hand, the reproduction is by a secondary process entirely separate and independent of the personal consciousness. In the examples I cited the latter was in entire ignorance of the reproduction which did not become a personally conscious mem- ory. At the very same moment when the experi- ences could not be voluntarily remembered, and without a change in the moment's consciousness, something was tapped, as it were, and thereby they were graphically revealed without the knowledge of the subject, without memory of them being intro- duced into the personal consciousness, and even without the subject being able to remember the in- cident after reading the automatic script. Even this stimulus failed to bring back the desired phase of consciousness. It was very much like surrepti- tiously inserting your hand into the pocket of an- other and secretly withdrawing an object which he thinks he has lost. What really happened was this : a secondary process was awakened and this process (of which the principal or personal consciousness was unaware) revealed the memory lost by the per- sonal consciousness. At least this is the interpreta- FORGOTTEN EXPERIENCES 47 tion which is the one which all the phenomena of this kind pertaining to subconscious manifestations compel us to draw.* At any rate the automatic script showed that somehow and somewhere outside the personal consciousness the experiences were con- served and under certain conditions could be repro- duced. We now also see that the same principle of repro- duction by a secondary process holds in hallucina- tory phenomena whether artificial or spontaneous, and in many dreams. When a person looking into a crystal sees a scene which is a truthful pictorial rep- resentation of an actual past experience which he does not consciously remember, it follows that that visual hallucination must be induced and con- structed by some secondary subconscious process outside of and independent of the processes in- volved in his personal consciousness. And, like- wise, when a dream is a translation of a forgotten experience into symbolical terms it follows that there must be, underlying the dream consciousness, some subconscious process which continues and translates the original experience into and con- structs the dream. This being so we are forced to two conclusions : first, in all these types of phenomena the secondary process must in some way be closely related to the * If the physiological interpretation be maintained, i. e., that the script was produced by a pure physiological process, this phenomenon would be a crucial demonstration of the nature of conservation, that it is in the form of physical alterations in nervous structure. I do not believe, however, that this interpretation can be maintained. 48 THE UNCONSCIOUS original experience in order to reproduce it; and, second, a mental experience must be conserved in some form which permits of a subconscious process reproducing the experience in one or other of the various forms in which memory appears. Further than this I will not go at present, not until we have more extensively reviewed the number and kinds of mental experiences that may be conserved. This we will do in the next lecture. CONSERVATION OF FORGOTTEN EXPERIENCES OF NORMAL, ARTIFICIAL, AND PATHOLOGICAL LIFE I. Normal Life (Continued) I have directed your attention up to this point to the conservation of experiences which at the time of their occurrence, although lost beyond voluntary recall, for the most part occupied the focus of at- tention of the individual were within the full light of consciousness. If these experiences were the only ones which were subject to conservation and I would have you still bear in mind that I am using the term only in the limited sense of the ability to recover an experience in some favorable condition, or moment of consciousness, or through some for- tunate or technical mode of reproduction if, I say, these were the only ones to be conserved, then the conservation of the experiences which make up our mental lives would be considerably curtailed. It so happens, however, that a large part of our mental activity is occupied with acts of which at the mo- ment we are only dimly aware or half aware in that they do not occupy the focus of attention. Some of these are what we call absent-minded acts. Again, many sensations and perceptions do not en- 49 50 THE UNCONSCIOUS ter the focus of attention, so that we are either not aware of them, or, if we are, there is so little vivid- ness attached to them that they are almost immedi- ately lost to voluntary memory. The same is true of certain trains of thoughts which course through the mind while one's attention is concentrated on some other line of thought. They are sometimes described as being in the background of the mind. Then, again, we have our dream life, and that of reverie, and the important artificial state of hyp- nosis ; also certain pathological states to which some individuals are subject, such as intoxication, hys- terical crises, deliria, and multiple personality. Ac- cordingly it is important in any investigation into the extent of the field of conservation to inquire whether all this mental life is only fleeting, eva- nescent, psychological experience, or whether it is subject to the same principle of conservation. If the latter be the case it presages consequences which are portentous in the possible multiplicity and manifoldness of the elements which may enter into and may govern the mechanism of mental pro- cesses. But let me not get ahead of my exposition. Absent-minded acts In a study made some time ago I recorded the reproduction, as a crystal vision, of an absent-minded act, i. e., one which had not fully entered the focus of consciousness during deep con- centration of the attention. It is a type of numer- ous experiments of this kind that I have made. Miss B. is directed to look into a crystal. She sees FORGOTTEN EXPERIENCES 51 therein a vision of herself walking along a particu- lar street in Boston in a brown study. She sees herself take out of her pocket some bank notes, tear them up, and throw them into the street. Now this artificial hallucination, or vision, was a picture of an actual occurrence; in an absent-minded reverie the subject had actually performed this very act under the circumstances portrayed in the vision and had retained no memory of it.* Similarly I have frequently recovered knowledge of the whereabouts of articles mislaid absent- mindedly. Sometimes the method used has been, as in the above examples, that of crystal gazing or artificial hallucinations; sometimes hypnotism, sometimes automatic writing, etc. By the last two methods not only the forgotten acts but the ideas and feelings which were outside the focus of atten- tion, but in the fringe of consciousness, and prompted the acts are described. It is needless to give the details of the observations; it suffices to say that each minute detail of the absent-minded act and the thoughts and feelings that determined it are described or mirrored, as the case may be. The point of importance is that concentration of atten- tion is not essential for conservation, and, there- fore, among the vast mass of the conserved ex- periences of life may be found many which, though * For a full account of this experiment, see An Experimental Study of Visions, Brain, Winter Number, 1898; The Dissociation, pp. 81, 82. 52 THE UNCONSCIOUS once conscious, only entered the margin of aware- ness (not the focus of attention) and never were subject to voluntary recollection. In the absence of attentive awareness at the time for such an experi- ence (and therefore of recollection), we often can only be assured that it ever occurred by circumstan- tial evidence. When this assurance is wanting we are tempted to deny its occurrence and our respon- sibility, but experiment shows that the process of conservation, like the dictagraph, is a more faithful custodian of our experiences than are our volun- tary memories. Subconscious perceptions It is not difficult to show that perceptions of the environment which never even entered the fringe of the personal conscious- ness, i. e., of which the individual was never even dimly aware, may be conserved. Indeed, the dem- onstration of their conservation is one of the im- portant pieces of evidence for the occurrence of co- conscious perception and, therefore, of the splitting of consciousness. Mrs. Holland, both by automatic writing and in hypnosis, describes perceptions of the environment (objects seen, etc.) of which she was not aware at the time. Miss B. and B. C. A. re- call, in hypnosis and by automatic writing, para- graphs in the newspapers read through casual glances without awareness thereof. The same is true of perceptions of the environment experienced under experimental conditions as well as fortui- tously. I have made a large number of experiments FORGOTTEN EXPERIENCES 53 and other observations of this kind, and have been in the habit of demonstrating before the students at my lectures this evidence of coconscious perception. A simple method is to ask a suitable subject to de- scribe the dress of some person in the audience, or of objects in the environment; if he is unable to do this, then to attempt to obtain as minute a descrip- tion as possible by automatic writing or verbally after he has been hypnotized. It is often quite sur- prising to note with what detail the objects which al- most entirely escaped conscious observation are sub- consciously perceived and remembered. Sometimes the descriptions of my students have been quite em- barrassing from their naive truthfulness to nature. The following is an example of such an observa- tion: I asked B. C. A. (without warning and after having covered her eyes) to describe the dress of a friend who was present and with whom she had been conversing for perhaps some twenty minutes. She was unable to do so beyond saying that he wore dark clothes. I then found that I myself was unable to give a more detailed description of his dress, al- though we had lunched and been together about two hours. B. C. A. was then asked to write a descrip- tion automatically. Her hand wrote as follows (she was unaware that her hand was writing) : "He has on a dark greenish gray suit, a stripe in it little rough stripe; black bow-cravat; shirt with three little stripes in it; black laced shoes; false teeth ; one finger gone ; three buttons on his coat. ' ' The written description was absolutely correct. 54' THE UNCONSCIOUS The stripes in the coat were almost invisible. I had not noticed his teeth or the loss of a finger and we had to count the buttons to make sure of their number owing to their partial concealment by the folds of the unbuttoned coat. The shoe strings I am sure, under the conditions, would have escaped nearly everyone 's observation. Subconscious perceptions even more than absent- minded acts offer some of the most interesting phe- nomena of conservation, for these phenomena give evidence of the ability, under certain conditions, to reproduce, in one mode or another, experiences which were never a phase of the personal conscious- ness, never entered even the fringe of the content of this consciousness and of which, therefore, we were never aware. For this reason they are not, properly speaking, forgotten experiences. Their reproduction sometimes produces dramatic effects. The following is an instance: B. C. A., waking one night out of a sound sleep, saw a vision of a young girl dressed in white, standing at the foot of her bed. The vision was extraordinarily vivid, the face so distinct that she was able to give a detailed de- scription of it. She had no recollection of having seen the face before, and it awakened no sense of familiarity. Suspecting, for certain reasons, the figure to be that of a young girl who had recently died and whom I knew that B. C. A. had never known and was not aware that she had ever seen, I placed before her a collection of a dozen or more photographs of different people among which was FORGOTTEN EXPERIENCES 55 one of this girl. This photograph she picked out as the one which most resembled the vision (it was a poor likeness) and automatic writing confirmed most positively the choice. Now it transpired that she had passed by this girl on one occasion while the latter was talking to me in the hall of my house, but she had purposely, for certain reasons, not looked at her. Subconsciously, however, she had seen her since she could give, both in hypnosis and by automatic writing, an accurate account of the incident, which I also remembered. B. C. A., how- ever, had no recollection of it. The subconscious perception was later reproduced (after having undergone secondary elaboration) as a vision. Similarly I have known paragraphs read in the newspapers out of the corner of her eye, so to speak, and probably by casual glances, not only, as I have said, to be recalled in hypnosis and by automatic writing, but to be reproduced with more or less elaboration in her dreams. She had, as the evidence showed, no awareness at the time of having read these paragraphs and no after recollection of the same. Experimentally, as I have said, it is possible to demonstrate other phenomena which are the same in principle. The experiment consists, after sur- reptitiously placing objects under proper precau- tions in the peripheral field of vision, in having the subject fix his eyes on central vision and his atten- tion distracted from the environment by intense concentration or reading. Immediately after re- 56 THE UNCONSCIOUS moving the objects it is determined that the subject did not consciously perceive them. But in hypno- sis or by other methods it is found that memory for perceptions of the peripheral objects returns, i. e., the perceptions are reproduced. Auditory stimuli may be used as tests with similar results. Likewise, with Miss B., I have frequently ob- tained reproductions of perceptions of which at the time she was unaware. This has been either under similar experimental conditions, or under acciden- tal circumstances when I could confirm the accuracy of the reproductions. For instance, to cite one out of numerous examples, on one occasion I saw her pass by in the street while I was standing on the door-step of a house some fifteen or twenty feet away, well outside the line of her central vision. She was in a brown study. I called to her three times saying, "Good morning, Miss B.," laying the accent each time on a different word. She did not hear me and later had no recollection of the episode. In hypnosis she recalled the circumstances accu- rately and reproduced my words with the accents properly placed. Such observations and experi- ments I have frequently made. They can be varied indefinitely in form and condition. The phenomenon of subconscious perception of sensory stimulations applied to anesthetic areas tactile, visual, etc.), in hysterics, first demon- strated by Janet, is of the same order, but has been so often described that only a reference to it is nec- essary. I mention examples here merely that the 57 different kinds of phenomena that may be brought within the sphere of memory shall be mentioned. For instance, Mrs. E. B.* has an hysterical loss of sensibility in the hand which, in consequence, can be severely pinched or pricked, or an object placed in it, etc., without her being aware of the fact. Not- withstanding this absence of awareness these tactile experiences were conserved since an accurate de- tailed memory of them is recovered in hypnosis, or manifested through automatic writing. The same phenomenon can be demonstrated in Mrs. B., whose right arm is anesthetic. f The same conservation of subconscious perceptions can be experimentally demonstrated during automatic writing. At such times the writing hand becomes anesthetic and if a screen is interposed so that the subject cannot see the hand he is not aware of any stimulations applied to it. Nevertheless such sensory stimulations a prick or a pinch or more complicated impressions are conserved, for the hand will accurately describe all that is done. An observation which I made on one of my sub- jects probably belongs here rather than to the pre- ceding types. Several different objects were suc- cessively brought into the field of vision, but so far toward the periphery that they could not be suffi- ciently clearly seen to be identified. In hypnosis, however, they were accurately described, showing * The Dissociation, p. 77. f For numerous observations of this kind, see Pierre Janet : The Mental States of Hystericals. 58 THE UNCONSCIOUS the conservation of perceptions that did not enter the vivid awareness or clear perception of the subject. It is true, as a study of the coconscious would show, that such phenomena of anesthesia and un- recognized perceptions are dependent upon a dis- sociation of consciousness and upon coconscious perception. But this is a matter of mechanism with which we are not now concerned. The point simply is that subconscious perceptions which never en- tered the awareness of the personal consciousness may be conserved. I will cite one more observation, one in which the reproduction was through secondary translation, as we shall see later that it belongs to a class which enables us to determine the nature of conservation. B. C. A., actuated by curiosity, looked into a crys- tal and saw there some printed words which had no meaning for her whatever and awakened no mem- ory of any previous experience. It was afterward found that these words represented a cablegram message which she unconsciously overheard while it was being transmitted over the telephone to the telegraph office by my secretary in the next room. She had no recollection of having heard the words, as she was absorbed in reading a book at the time. The correctness of the visual reproduction is shown, not only by automatic writing which remembered and recorded the whole experience, but also by com- parison with the original cablegram. Again, in other experiments there appear, in the crystal, visions rich in detail of persons whom she FOKGOTTEN EXPERIENCES 59 does not remember having seen, although it can be proved that she actually has seen them. The reproduction of subconscious perceptions and forgotten knowledge in dreams, visions, hypnosis, trance states, by automatic writing, etc., is interest- ing apart from the theory of memory. Facts of this kind offer a rational interpretation of many well-authenticated phenomena exploited in spiritis- tic literature. Much of the surprising information given by planchette, table rapping, and similar de- vices commonly employed by mediums, depends upon the translation of forgotten dormant experi- ences into manifestations of this sort. In clinical medicine, too, we can often learn, through repro- ductions obtained by special methods of investiga- tion, the origin of obsessions and other ideas which otherwise are unintelligible. Dreams and somnambulisms Many people remember their dreams poorly or not at all, and, in the latter case, are under the belief that they do not dream. But often circumstantial evidence, such as talking in their sleep, shows that they do dream. Now, though ordinarily they cannot remember the dreams, by changing the waking state to an hyp- notic one, or through the device of crystal visions or automatic writing, it is possible in some people to reproduce the whole dream. Amnesia for dreams, therefore, cannot be taken as evidence that they do not occur, and forgotten dream consciousness is subject to the same principles of conservation and 60 THE UNCONSCIOUS reproduction as the experiences of waking life. Thus in B. C. A. dreams totally forgotten on awak- ening are easily recovered in hypnosis and in crys- tal visions.* In the case of M 1, which I cited to you a little while ago, the forgotten dream in which he lived over again the original episode which led to the development of his hysterical condition and which when repeated in the dream induced each successive attack, was easily recovered in hypnosis. The same was true of the forgotten dreams of Mrs. H. and Miss B. The reproduction of nocturnal somnambulistic acts and the ideas which occupied the content of consciousness of the somnambulist can be effected in the same manner. I have quite a collection of observation of this kind. In the study of visions,! to which I have already referred, may be found the observation where Miss B., looking into a crystal, sees herself walking in her sleep and hiding some money under a tablecloth and books lying on the table. The money (which was supposed to have been lost) was found where it was seen in the vision. In my notebook are the records of numerous arti- ficial hallucinations of this kind which reproduce sleep-walking acts of B. C. A. To cite one instance : in the crystal she sees herself arise from her bed, turn on the lights, descend the stairs, enter one of the lower rooms, sit by the fire in deep, pensive re- * The Mechanism and Interpretation of Dreams, loc. cit. f Loc. cit. See p. 51. FORGOTTEN EXPERIENCES 61 flection, then get up and dance merrily as her som- nambulistic mood changes. Presently, as the cine- matograph-like picture unfolds itself in the crystal, she sees herself go to the writing table, write two letters, ascend the stairs, dropping one letter on the way,* reenter her room, open a glove box, place the remaining letter under the gloves, and finally put out the lights and get into bed when, with the ad- vent of sleep, the vision ends. In the vision the changing expression of her face displays each suc- cessive mood. In hypnosis also the scene is remem- bered and then even the thoughts which accompa- nied each act of the somnambulist are described. Here again, then, we have evidence that even for- gotten dreams and somnambulistic thoughts are not lost but under certain special conditions can be re- vived in one mode or another. II. Forgotten Experiences of Artificial and Pathological States The experiences that I have thus far cited in evi- dence of the principle of the conservation of dor- mant experiences that cannot be voluntarily re- called have been drawn almost entirely from normal everyday life. We now come to a series of facts which are very important in that they show that what is true of the experiences of everyday life is also true of those of artificial and pathological states of which the normal personal consciousness has no cognizance. These facts are also vital for * See Lecture VI, p. 185. 62 THE UNCONSCIOUS the comprehension of post-hypnotic phenomena, of amnesia, multiple personality, and allied dissoci- ated states. Let us consider some of the states from the point of view of conservation. Artificial states After a person passes from one dissociated state to another, or from a dissociated state to the full waking state, it is commonly found that there is amnesia for the previous state. This is a general principle. The forgetting of dreams is an example from normal life. For the psychological state of sleep in which dreams occur is one of nor- mal dissociation of consciousness by which the per- ception of the environment, and the great mass of life's experiences, can no longer be brought within the content of the dream consciousness. Hence there is a general tendency to the development of amnesia for dreams after waking when the normal synthesis of the personality has been established. Yet, as we have seen, forgotten dreams can gener- ally be recalled in hypnosis or by some other techni- cal method (e. g., crystal visions and abstraction). Now hypnosis is an artificially dissociated state. After passing from one hypnotic state to another,* or after waking, it is very common to find complete * Gurney was among the first to demonstrate the induction of several states in the same subject. He was able to obtain three dif- ferent hypnotic states (Proceedings S. P. R., Vol. IV, p. 515), and Mrs. Sidgwick and Miss Johnson eight in one individual, each with amnesia for the other. Janet, of course, demonstrated the same phenomena. In the cases of Miss B and B. C. A. I obtained a large number of such states. FORGOTTEN EXPERIENCES 63 amnesia for the whole of the experience belonging to the previous hypnotic state. By no effort whatso- ever can it be recalled and this inability persists during the remainder of the life of the subject. And yet those hypnotic experiences may have been very extensive, particularly if the subject has been hyp- notized a great many times. Nevertheless, it is easy to demonstrate that they are conserved and therefore, like all conserved experiences, potentially still existing, subject to recall under favoring con- ditions ; for, as is well known, if the subject be re- hypnotized they are recalled as normal memories. With the restitution of the hypnotic state the mem- ories which were dormant become synthesized with the hypnotic personality and conscious. The method of producing crystal visions may also be used to demonstrate the dormant conservation of experiences originating in hypnotic states. By this method and that of automatic writing, as I have already explained, the memories may be made to reveal themselves, without inducing recollection, at the very moment when the subject cannot voluntar- ily recall them. The subject, of course, being ig- norant of what happened in hypnosis cannot recog- nize the visions as pictorial memories. In illustra- tion of this I would recall the observation in the case of Miss B. where, in such an artificial vision, she saw herself sitting on a sofa smoking a cigar- ette.* This vision represented an incident which * Morton Prince : The Dissociation, p. 55 ; also An Experimental Study of Visions, Brain, Winter Number, 1898. 64 THE UNCONSCIOUS occurred during one of the subject's hypnotic states when she had smoked a cigarette. Naturally Miss B., in her ignorance of the facts, denied the truth- fulness of the vision. Other examples of a like kind might be cited if it were necessary. By automatic writing, also, evidence of the same principle may be obtained. The conserved mem- ories are tapped, so to speak. Thus I suggest to Mrs. B. in hypnosis that after waking she shall write certain verses or sentences. After being awakened she reproduces automatically, as di- rected, the desired verses or sentences which, of course, belonged to her hypnotic experiences.* In other words, although the personal consciousness did not remember the hypnotic experience of hav- ing received the command and of having given the promise to write the verses, etc., the automatic writ- ing by the act of fulfilling the command showed that all this was conserved; here again was evidence of conservation, in some form, of an experience at the very moment when the personal consciousness was un- able to voluntarily recall what had taken place in hyp- nosis. Such experiments may be varied indefinitely. The following is an instance of the same phe- nomenon obtained by tapping without the use of previous suggestion in hypnosis: subject B. C. A. One of the hypnotic states, b, was waked up to be- come B, this change being followed, as usual, by am- * Some of the Revelations of Hypnotism, Boston Medical and Surgical Journal, May 22, 1890. 65 nesia. By means of automatic writing an accurate account was now obtained of the experiences which had taken place during the previous moments in hypnosis, the subject being unaware of what the hand wrote. Here were complete memories of the whole period of which the personal consciousness, B, had no knowledge. One of the most striking, not to say dramatic, demonstrations of this kind can sometimes be obtained in cases exhibiting several different hypnotic states. For instance: "c" and "b" are two different hypnotic phases belonging to the same individual (B. C. A.), c knows nothing of the experiences of b, and b nothing of c, each hav- ing amnesia for the other. Now one has only to whisper in the ear of c, asking a question of b, and at once, by automatic speech, the dormant b phase responds, giving such information as is sought in proof of the conservation of any given experience belonging to the tapped b phase. The consciousness of c apparently continues uninterruptedly during the experiment. The same evidence could be ob- tained by automatic writing under the same condi- tions. Again in the b phase another state known as "Alpha and Omega" can be tapped, giving similar evidence of conservation. In the case of Miss B. the same phenomena could be elicited. In this respect hypnotic states may show the same behavior as alter- nating personalities of which I shall presently speak. Suggested post-hypnotic phenomena depend, in part, on the conservation of dormant complexes. In hypnosis I give a suggestion that the subject on 66 THE UNCONSCIOUS waking shall, at a given moment, take a cigarette and smoke it. There is thus formed a complex of ideas which becomes dormant and forgotten after waking. Later, by some mechanism which we need not inquire into now, the ideas of the dormant com- plex enter the field of the personal self ; the idea of smoking a cigarette arises therein and the subject puts the idea into execution. These consequences of the suggestion could not occur unless the expe- riences were conserved. Or, we may take an ex- periment where the hypnotic experiences are repro- duced automatically by writing. Here the conserved experiences form a secondary system split off from the personal consciousness. This system repro- duces the hypnotic experiences as memory outside of the personal consciousness. From a practical point of view this principle of the conservation of the experiences of the hypnotic state is of the utmost importance. The fact that a person does not remember them on waking if such be the case is of little consequence in principle, and, practically, this amnesia does not preclude these experiences from influencing the waking per- sonality. As experiences and potential memories they all belong to and are part of the personality. The hypnotic experiences being conserved our per- sonality may still be modified and determined in its judgments, points of view, and attitudes by them, as by other unrecognized memories when such modifi- cations have been effected in the hypnotic state. FORGOTTEN EXPERIENCES 67 When the last is the case the hypnotically modified judgments, etc., may introduce themselves into the content of consciousness in the waking state by association without being recognized as memories. There may be no recollection of the source of the new ideas, of the reason for the modification of a given judgment or attitude of mind, because there is no recollection of the hypnotic state as a whole; but so far as the new judgment or attitude is a re- production of an hypnotic experience it is memory, although not perfect memory or recollection in the sense of localizing the experience in the past. This principle can easily be demonstrated experi- mentally. It is only necessary, for instance, to state to a suitably suggestible subject that the weather, with which previously he was discontented is, after all, fine; for although it is raining, still, the crops need rain ; it will allay the dust and make motoring pleasant, it will give him an opportunity to finish his neglected correspondence, etc. The whole pros- pect, he is told, is pleasing. He accepts, we assume, the new point of view. He is then waked up and has complete amnesia for the experience. Now these ideas, developed in the hypnotic state, are con- served as potential memories. Though with the change of the moment-consciousness they cannot be voluntarily recalled, they have entered into associa- tions to form a new viewpoint. Just speak to him about the weather and watch the result. His dis- content has disappeared and given place to satisfac- tion. He expresses himself as quite pleased with 68 THE UNCONSCIOUS the weather and gives the same reasons for his sat- isfaction as were suggested to and accepted by him in hypnosis. He does not recognize his new views as reproductions, i. e., memories,, of previous experi- ences because he has no recollection of the hypnotic state. He does not remember when and how he changed his mind; but these experiences have de- termined his views because they have become a part of his conscious system of thought. The principle applies to a large part of our judgments not formed in hypnosis. There is nothing very remarkable about it. The process is similar to that of ordinary thought though it has had an artificial and differ- ent origin. The complex of ideas having been formed in, hypnosis still remains organized and some of its elements enter the complexes of the per- sonal consciousness, just as in normal life ideas of buried experiences of which we have no recollection intrude themselves from time to time and shape our judgments and the current of our thoughts without our realizing what has determined our mental proc- esses. We have forgotten the source of our judg- ments, but this forgetfulness does not affect the mechanism of the process. Pathological states In the functional amnesias of a pathological character we find the same phenome- non of conservation. Various types of amnesia are encountered. I will specify only the episodic, epochal, and the continuous, so commonly observed in hysteria. This field has been threshed over by FORGOTTEN EXPERIENCES 69 many observers and I need refer only to a few in- stances as illustrations. In the first two types the experiences which are forgotten may have occurred during the previous normal condition. In the epi- sodic the particular episode which is forgotten may have been, strangely enough, one which from the very important part it played in the life of the sub- ject and its peculiar impressiveness and signifi- cance we should expect would be necessarily remem- bered, especially as memory in other respects is nor- mal. But for the same reasons it is not surprising to find that the experience has been conserved some- how and somewhere although it cannot be recalled. The classical cases of Fraulein 0. and Lucy B. re- ported by Breuer and Freud * are typical. From my own collection of cases I will cite the following episode from the case of B. C. A. This subject received a mental shock as the result of an emotional conflict of a distressing character. This experience was the exciting factor in the develop- ment of her psychosis, a dissociation of personality. In the resulting "neurasthenic" state, although her memory was normal for all other experiences of her life, this particular episode with all its manifold de- tails, notwithstanding its great significance in her life, completely dropped out of her memory.f This incident was a very intimate one and it is not necessary to give the details. When put to the * Studien iiber Hysterie. t Of course I am not discussing here the genetic mechanism of the amnesia, being concerned only with the principle of conservation. 70 THE UNCONSCIOUS test all effort to recall the episode voluntarily is without result, and even suggestions in two hypnotic states fail to awaken it in those states. Yet when a pencil is put in her hand these memories are made to manifest themselves by automatic writing. During the writing the subject remains in a perfectly alert state but is unaware of what her hand is doing. At a later period after the subject had been restored to the normal condition she could voluntarily recall these memories thus, again, showing their conservation. One other example of episodic amnesia I will cite, inasmuch as, aside from the question of conserva- tion, it is of practical importance, being typical of experiences which lead to obsessions of phobia. The subject, 0. N., had an intense fear of towers such as might contain bells that might ring. She had no recollection of the first occasion when the fear occurred or of any experience which might have given rise to it, and, of course, could give no explanation of the obsession. Neither in abstrac- tion or hypnosis could any related memories be evoked, but by automatic writing she "uncon- sciously" described an emotional and dramatic scene which was the occasion of the first occurrence of the fear and which had taken place some twenty- five years previously when she was a young girl. With the reason for the amnesia we are not par- ticularly concerned at present excepting so far as it serves to make clear the distinction between recol- lection and conservation, and to throw light on the nature of the latter. The episodes in both these in- FORGOTTEN EXPERIENCES 71 stances were of a strongly emotional character. Now we have known for many years from numerous observations that emotion tends to disrupt the mind and to dissociate the experiences which give rise to the affective state so that they cannot be brought back into consciousness. We may particularize further and, making use of the known impulsive force of emotion, attribute the dissociation (or inhi- bition) in many cases to a conflict between certain ideas belonging to the experience and other oppos- ing ideas which, with the emotion, they have awak- ened. The impulsive force of the latter ideas, being the stronger, dissociates, or, to use the expressive term introduced by Freud, represses, the former. The principle of dissociation by conflict has been formulated and elaborated by Freud in his well- known theory which has been made use of to explain all functional amnesias. It is not necessary to go as far as that, nor does the theory as such concern us now. It is sufficient if in certain cases the amnesia (or dissociation) is a dissociation (repression) in- duced by the conative force of conflicting emotion. If so we should expect that the amnesia would be of a temporary nature and would continue only so long as the conflict and dissociating force continued. In any favorable moment when repression ceased or failed to be operative, as in hypnosis or abstraction, reproduction (recollection) could occur. But this requires that the registration of the experience should be something specific that can be dissociated without obliteration. And, further, it must be some- 72 THE UNCONSCIOUS thing that can be so conserved, somehow and some- where, during dissociation that, as in the case of reproduction by automatic writing, it can escape the influence of the repressing force and express itself autonomously, i. e., without the expressed memory of the experience entering the personal conscious- ness. To this we shall return later. In the two examples I have cited, if my interpre- tation is correct, the amnesia was due to dissocia- tion by conflict and hence the conservation, as is the rule in functional dissociation, and the reproduc- tion by automatic writing. This principle of dis- sociation by conflict and of conservation of the dis- sociated remembrances is of great practical impor- tance as we shall see in later lectures. It can be best studied experimentally with cases of multiple personality. In the case of Miss B. numerous ex- amples of amnesia from conflict were observed. Owing to the precise organization of the conscious- ness into two distinct personalities it was possible to definitely determine beyond question the antago- nistic ideas of one personality which voluntarily in- duced the conflict and, by the impulsive force of their emotion, caused the amnesia in the other personal- ity.* The same phenomena were observed in the case of B. C. A. As memory for the forgotten expe- riences in these instances returned as soon as the conflict ceased, conservation of them necessarily persisted during the amnesia. * The Dissociation, pp. 284-5, 456-9. FORGOTTEN EXPERIENCES 73 Perhaps I may be permitted to digress here slightly to point out that this same (in principle) phenomenon may be effected experimentally by sug- gestion. The suggested idea which has the force of a volition or unexpressed wish, coming in conflict with the knowledge of previously familiar facts, in- hibits or represses the reproduction in conscious- ness of this knowledge as memory. It is easy to prove, however, that this knowledge is conserved though it cannot be recalled. Thus, I give appro- priate suggestions to B. C. A. in hypnosis that she shall be unable, when awake, to remember a certain unpleasant episode connected with a person named ' ' August ' ' After being awakened she has complete amnesia, not only for the episode, but even for the name. The suppression of the memory of the epi- sode carries with it by association the name of the person. In fact, the name itself has no meaning for her. When asked to give the names of the calendar months after mentioning ( l July ' ' she hesitates, then gives "September" as the next. Even when the name "August" is mentioned to her it has no mean- ing and sounds like a word of a foreign language. The memory of the episode has become dormant so far as volitional recollection is concerned. It can, however, be recalled as a coconscious process through automatic writing, as in the preceding ex- periment, and then the word in all its meanings and associations is also awakened in the coconsciousness. The same phenomenon may be observed clini- cally in transition types standing halfway between 74 THE UNCONSCIOUS the amnesia following emotional episodes and that produced by external suggestion. Auto-suggestion may then be a factor in the mechanism, as in the following example : In a moment of discouragement and despair B. C. A., torn by an unsolved problem, said to herself after going to bed at night, * ' I shall go to sleep and I shall forget everything, my name and everything else. ' ' Of course she did not intend or expect to forget literally her name, but she gave expression to a petulant despairing conditional wish which if fulfilled would be a solution to her prob- lem; as much as if she said, "If I should forget who I am my troubles would be ended." Nevertheless the auto-suggestion with its strong feeling tones worked for repression. The next day, when about to give her name by telephone, she discovered that she had forgotten it. On testing her later I found that she could not speak, write, or read her name. She could not even understandingly read the same word when used with a different signification, i. e., stone [her name, we will suppose, is Stone], nor the letters of the same. This amnesia persisted for three days until removed by my suggestion. That the lost knowledge was all the time conserved is further shown by the fact that during the amnesia the name was remembered in hypnosis and also re- produced by automatic writing. In the epochal type of amnesia a person, per- haps after a shock, suddenly loses all memory for lost epochs, it may be for days and even for years of FORGOTTEN EXPERIENCES 75 his preceding life. In the classical case of Mr. Hanna, studied by Boris Sidis, the amnesia was for his whole previous life, so that the subject was like a new-born child. It is easy to show, however, that the forgotten epoch is normally conserved by mak- ing use of the various methods of reproduction at our disposal. In the case of Hanna, Sidis was able through "hypnoidization" and suggestion to bring back memory pictures of the amnesic periods. "While the subject's attention is thus distracted, events, names of persons, of places, sentences, phrases, whole paragraphs of books totally lapsed from memory, and in language the very words of which sounded bizarre to his ears and the meaning of which was to him inscrutable all that flashed lightning-like on the patient's mind. So successful was this method that on one occasion the patient was frightened by the flood of memories that rose suddenly from the obscure subconscious [uncon- scious] regions, deluged his mind, and were ex- pressed aloud, only to be forgotten the next moment. To the patient himself it appeared as if another be- ing took possession of his tongue."* In another class of cases of epochal amnesia known as fugues the subject, having forgotten his past life and controlled by fancied ideas, perhaps wanders away not knowing who he is or anything of the previous associations of his life. The "Lowell Case" of amnesia, which I had an opportunity to * Boris Sidis : The Psychology of Suggestion, p. 224 ; see also Multiple Personality, p. 143. 76 THE UNCONSCIOUS carefully observe and which later was more exten- sively studied for me by Dr. Coriat, may be in- stanced.* A woman suddenly left her home with- out apparent rhyme or reason. When later found she had lost all recollection of her name, her person- ality, her family, and her surroundings, and her iden- tity was only accidentally discovered through the pub- lication of her photograph in the newspaper. She then had almost complete amnesia for her previous life. Another case, also studied by Dr. Coriat and the writer, was that of a policeman who suddenly de- serted his official duty in Boston and went to New York, where he wandered about without knowledge of who he was, his name, his age, his occupation, in- deed, as there is reason to believe, of his past life. When he came to himself three days later he found himself in a hospital with complete amnesia for the three days' fugue. When I examined him some days later this amnesia still persisted but Dr. Coriat was able to recover memories of his vagrancy in New York showing that the experiences of this fugue were still conserved. It is hardly necessary to remind you that, of course, the memories of his normal life which during the fugue it might have been thought were lost were shown to have been conserved, as on " coming to himself ' ' they were re- covered. In the ''Lowell Case" substantially simi- lar conditions were found. In continuous or anterograde amnesia the subject forgets every experience nearly as fast as it hap- * The Journal of Abnormal Psychology, Vol. II, p. 93. FORGOTTEN EXPERIENCES 77 pens. The classical case of Mme. D., studied by Charcot and later more completely by Janet, is an example. The conservation of the forgotten experi- ences was demonstrated by these authors. In multiple personality amnesia for large epochs in the subject's life is quite generally a prominent feature. In one phase of personality there is no knowledge whatsoever of existence in another phase. Thus, for instance, all the experiences of BI and BIV, in the case of Miss B., were respec- tively unknown to the other. When, however, the change took place from one personality to the other, with accompanying amnesia, all the great mass of experiences of the one personality still remained organized and conserved during the cycle of the other's existence. With the reversion to the first personality, whichever it might be, the previously formed experiences of that personality became ca- pable of manifesting themselves as conscious mem- ories. This conservation could also be shown, in this case, by the method of tapping the conserved memories and producing crystal visions or artificial hallucinations. Those who are familiar with the published account of the case will remember that BIV was in the habit at one time of acquiring knowl- edge of the amnesic periods of BI's existence by " fixing" her mind and obtaining a visual picture of the latter 's acts. Likewise, it will be remembered that by crystal visions I was enabled to bring into consciousness a vision of the scene at the hospital 78 THE UNCONSCIOUS which, through its emotional influence, caused the catastrophe of dissociation of personality, and also of the scene enacted by BI just preceding the awak- ening of BIV, of all of which BIV had no knowl- edge.* As with Mr. Hanna sometimes these mem- ories instead of being complex pictures were scrappy mere flashes in the pan. The same condition of conservation of the experiences of one personality during the existence of another obtained in the case of B. C. A. and numerous cases recorded in the lit- erature. In this respect the condition is the same as that which obtains in hypnotic states and which I mentioned a few moments ago. We may, in fact, lay it down as a general law that during any dissociated state, no matter how exten- sive or how intense the amnesia, all the experiences that can be recalled in any other state, whether the normal one or another dissociated state, are con- served and, theoretically at least, can be made to manifest themselves. And, likewise and to the same extent, during the normal state the experi- ences which belong to a dissociated state are still conserved, notwithstanding the existing amnesia for those experiences. Furthermore, if we were deal- ing with special pathology we would be able to show that many pathological phenomena are due to the subconscious manifestations of such conserved and forgotten experiences. Observation shows that the experiences of trance states and allied conditions are similarly conserved. * The Dissociation, pp. 220, 221, 255, 531, 532. 79 Fanny S., as the result of an emotional shock, due to a distressing piece of news, goes into a trance- like state of which she has no memory afterwards. Later, a recollection of this supposedly unconscious state, including the content of her trance thoughts and the sayings and doings of those about her, is recovered by a special device. B. C. A. likewise fell into a trance of which there was no recollection. The whole incident was equally fully recovered in a crystal vision, and also conscious memory of it brought back to personal consciousness by a special technic. In the vision she saw herself apparently unconscious, the various people about her each per- forming his part in the episode ; the doctor admin- istering a hypodermic dose of medicine, etc. In hypnosis she remembered in addition the thoughts of the trance consciousness and the various remarks made by different people in attendance. Even delirious states for which there is complete amnesia may be conserved. I have observed numer- ous instances of this in the case of Miss B. For in- stance, the delirious acts occurring in the course of pneumonia were reproduced in a crystal vision by Miss B. and the delirious thoughts as well were re- membered by the secondary personality, Sally.* I have records of several examples of conservation of delirium in this case. Quite interesting was the repetition of the same delirium due to ether narcosis in succeeding states of narcosis as frequently hap- pened. A very curious phenomenon of the same or- * The Dissociation, p. 83. 80 THE UNCONSCIOUS der was the following: After the subject had been etherized a number of times I adopted the ruse of pretending to etherize one of the secondary per- sonalities, using the customary inhaler but without ether. The efficient factor was, of course, sugges- tion. The subject would, at least apparently, be- come unconscious, passing into a state which had all the superficial appearances of deep etherization. At the end of the procedure she would slowly return to consciousness, repeat the same stereotyped exple- tives and other expressions which she regularly made use of when ether was actually used, and make the same grimaces and signs of discomfort, etc. This behavior would seem to indicate that the mental and physical experiences originally induced by a physical agent were conserved and later reproduced under imaginary conditions. Mental experiences formed in states of alcoholic intoxication without delirium may be conserved as dormant complexes. Dr. Isador Coriat,* in his studies of alcoholic amnesia, was able to restore memories of experiences occurring during the alco- holic state showing that they were still conserved. The person, during the period for which later there is amnesia, may or may not be what is ordinarily called drunk, although under the influence of alco- hol. Later, when he comes to himself, he is found to have forgotten the whole alcoholic period perhaps several days or a week during which he may have acted with apparently ordinary intelligence, and * The Journal of Abnormal Psychology, Vol. I, No. 3. FORGOTTEN EXPERIENCES 81 perhaps have committed criminal acts. By one or another of several technical methods memory of the forgotten period may often be recalled. Dr. C. W. Pilgrim * also has reported two cases of this kind in which he succeeded in restoring the memories of the forgotten alcoholic state. I might also recall here the case, cited by Ribot, of the Irish porter who, having lost a package while drunk, got drunk again and remembered where he had left it. Of course, in order to demonstrate the conserva- tion of forgotten experiences it is necessary, when abstraction is not sufficient, to employ subjects in whom more profound dissociation of consciousness can be produced by one or another of the artificial means described so as to permit of the reproduction of the hidden (conserved) experiences of mental life. Such subjects, however, are sufficiently com- mon. Often the passive state of abstraction after some practice is sufficient. Summary Although in the above resume of the phenomena of memory I have for the most part made use of personal observations, these, so far as the phenom- ena themselves are concerned, are in accord with those of other observers. It would have been easy to have drawn for corroboration upon the writings of Gurney, Janet, Charcot, Breuer, Freud, Sidis, Coriat, and others. * American Journal of Insanity, July, 1910. 82 THE UNCONSCIOUS A survey of all the facts which I have outlined in this lecture forces us to ask ourselves the question : To what extent are life's experiences conserved? Indeed it was to meet this question that I have re- viewed so large a variety of forgotten experiences which experiment or observation in individual cases has shown to be conserved. If my aim had been to show simply that an experience, which has been lost beyond all possible voluntary recall, may still be within the power of reproduction when special de- vices adapted to the purpose are employed, it would not have been necessary to cover such a wide field of inquiry. To meet the wider question it was necessary to go farther afield and examine a large variety of experiences occurring in multiform con- ditions of mental life. After doing this the important principle is forced upon us in strong relief that it matters not in what period of life, or in what state, experiences have occurred, or how long a time has intervened since their occurrence ; they may still be conserved. They become dormant, but under favorable conditions they may be awakened and may enter conscious life. We have seen, even by the few examples I have given, that childhood experiences that are supposed to have long been buried in oblivion may be con- served. We have seen that the mental life of arti- ficial and pathological states is subject to the same principle; that the experiences of hypnosis, trance rtates, deliria, intoxication, dissociated personality though there may be absolute amnesia in the nor- FORGOTTEN EXPERIENCES 83 mal waking state for them may still be capable of reproduction as memory. Yet of the vast num- ber of mental experiences which we have during the course of our lives we can voluntarily recall but a fractional part. What proportion of the others is conserved is difficult, if not impossible, to determine. The difficulty is largely a practical one due to the inadequacy of our technical methods of investiga- tion. In the first place, our technic is only applica- ble to a limited number of persons. In the second place, it is obvious that when an episode occurring in the course of everyday life is forgotten, but is recovered under one or another of the conditions I have described, it is only in a minority of instances that circumstances will permit confirmation of this evidence by collateral and independent testimony. Still, if we take the evidence as a whole its cumula- tive force is such as to compel the conviction that a vast number of experiences, more than we can possibly voluntarily recall, are conserved, and that it is impossible to affirm that any given experience may not persist in a dormant state. It is impossible to say what experiences of our daily life have failed to be conserved and what are awaiting only a favor- able condition of reproduction to be stimulated into activity as memory. Even if they cannot be repro- duced by voluntary effort, or by some one particular device, they may be by another and, if all devices fail, they may be recovered in pathological condi- tions like delirium, trance, spontaneous hallucina- tions, etc., or in normal dissociated states like 84 THE UNCONSCIOUS dreams. The inability to recall an experience is no evidence whatever that it is not conserved. Indeed, even when the special methods and moments fail it is still not always possible to say that it is not con- served. It would be a gross exaggeration to say, on the basis of the evidence at our disposal, that all life's experiences persist as potential memories, or even that this is true of the greater number. It is, how- ever, undoubtedly true that of the great mass of experiences which have passed out of all voluntary recollection, an almost incredible, even if relatively small, number still lie dormant, and, under favoring conditions, many can be brought within the field of conscious memory. The significance of this fact will become apparent to us later after we have studied the nature of conservation. Still more sig- nificant, particularly for abnormal psychology, is the fact we have brought out by our technical meth- ods of investigation; namely, that almost any con- served experience under certain conditions can function as a subconscious memory and become translated into, i.e., produce sensory and motor automatic phenomena, such as hallucinations, writ- ing, speech, etc. It will not be surprising if we shall find that various other disturbances of mind and body are produced by such subconscious processes. Two striking facts brought out by some of these investigations are the minuteness of the details with which forgotten experiences may be conserved and the long periods of time during which conserva- 85 tion may persist. Thus, as we have seen, experi- ences dating back to early childhood may be shown to be preserved in extremely minute detail though the individual has long forgotten them. Further- more, it has been shown that even remembered experiences may be conserved in far more elaborate detail than would appear from so much of the experience as can be voluntarily recalled. Prob- ably our voluntary memory is not absolutely perfect for any experience in all its details but the details that are conserved often far exceed those that can be recalled. In the survey of life's experiences which we have studied we have, for the most part, considered those which have had objective relation and have been subject to confirmation by collateral testimony. But we should not overlook the fact that among mental experiences are those of the inner as well as outer life. To the former belong the hopes and aspira- tions, the regrets, the fears, the doubts, the self- communings and wrestlings with self, the wishes, the loves, the hates, all that we are not willing to give out to the world, and all that we would forget and would strive not to admit to ourselves. All this inner life belongs to our experience and is subject to the same law of conservation. Finally, it should be said that much of what is not ordinarily regarded as memory is made up of conserved experiences. A large part of every men- tal content is memory the source of which is for- gotten. Just as our vocabulary is memory, though 86 THE UNCONSCIOUS we do not remember how and where it was acquired, so our judgments, beliefs, and opinions are in large part made up of past experiences which are for- gotten but which have left their traces as integral parts of concepts ingrained in our personalities. LECTURE IV CONSERVATION A RESIDUUM OF EXPERIENCES A consideration of all the facts of observation and experiment of the kind which I have recited in the last two lectures and I might have multiplied them many times forces us to the conclusion that whether or not we can recall any given experience it may be still conserved. Bear in mind that I have used conservation, thus far, only in the sense that under favoring changes in the moment's conscious- ness, or by special methods of stimulation, a past experience may reproduce itself, or may be made to reproduce itself, in one form or another of memory. It may be, for example, that you have to-day only a vague and general recollection of the last lecture and if you should endeavor to write an account of it from memory the result would be but a fragmen- tary report. And yet it is quite possible that, if one or another of the various technical methods I have described could be applied to some one of you, we should be able to recover quite exact memories, of certain portions at least, of the lecture perhaps verbqtim transcripts of certain portions, and large 87 88 THE UNCONSCIOUS numbers of facts which are quite beyond your pres- ent recollection. Our study of those phenomena of memory which I cited in the last lecture was carried only so far as to allow us to draw the conclusions as to con- servation which I have just stated. And, in draw- ing these conclusions, let me repeat we have pro- visionally limited the meaning of the term conserva- tion simply to the potential ability to reproduce ex- periences, with or without recollection, either in their original form, or translated into a graphic, visual, or auditory expression of them. We have not attempted from these phenomena to draw con- clusions as to the nature of conservation, or as to whether it is anything apart from reproduction under favorable conditions. If we do not look be- low the surface of the phenomena it might be held that memory is only a recurrent phase of conscious- ness, and that the term conservation is only a figure of speech to express the ability to determine that recurrence in our self -consciousness. Let us examine now a little more closely some of the phenomena we have already examined but in- adequately. Residual processes underlying automatic motor phe- nomena: writing, speech, gestures, etc. We will take writing as a type and the following as an example : In a state of hypnosis a subject learns a verse by heart. It is then suggested that this verse shall be written automatically after he has been awak- A RESIDUUM OP EXPERIENCES 89 ened. (By arranging the conditions of the experi- ment in this way we make certain that the script afterwards written shall express a memory and not a fabrication.) After the subject returns to the normal waking state he has complete amnesia for the whole hypnotic state and therefore for the verse. Now, if the experiment is successful, his hand writes the given verse without the subject being aware of what his hand is writing, and it may be without being aware that his hand is writing anything at all. The whole thing has been done without participation of his consciousness and with- out his knowing that any such phenomenon was to occur. (Of course any of his conscious experiences while in the hypnotic state might have been used as a test, these being known to the experimenter as well.) Now the things to be noted are: 1, that the script expresses a memory; that is, reproduces previous conserved conscious ideas the verse. It expresses memory just exactly as it would express it if it had been consciously and voluntarily written. 2, that these ideas while in a state of conservation and without entering consciousness i. e., becoming conscious memory express themselves in written language. 3, that this occurs while the subject has complete amnesia for the conserved ideas and therefore he could not possibly reproduce them as conscious memory. 4, that that which effects the writing is not a 90 THE UNCONSCIOUS recurring phase of the self -consciousness which is concerned at the moment with totally different ideas. 5, that the "state of conservation" is, at least during the writing, a specific state existing and functioning independently and outside of the per- sonal self-consciousness. 6, that in functioning it induces specific processes which make use of the same organized physiological mechanisms which ordinarily are made use of by conscious memory to express itself in writing and that these processes are not in, but independent of, consciousness. We are forced to conclude therefore that a con- scious experience in this case the ideas of the verse is conserved through the medium of some kind of residuum of itself capable of specific functioning and inducing processes which reproduce in the form of written symbols the ideas of the original experi- ence. We need not consider for the present the nature of the residuum, and its process, whether it is the ideas themselves or something else. Residual processes underlying hallucinations. We will take the observation of B. C. A. looking into a crystal and reading some printed words a cable- gram which she had previously unconsciously overheard.* The words were, let us say, "Best Wishes and a Happy New Year." This visual pic- ture was not a literal reproduction of the original * Lecture III, p. 58. A RESIDUUM OF EXPERIENCES 91 experience, which was a subconscious auditory ex- perience of the same words, of which she was not aware; but plainly, nevertheless, the visual picture must have been determined somehow by the audi- tory experience. Equally plainly the visual image was not a recurrent phase of the consciousness, for the words of the message had not been previously seen. What occurred was this : the antecedent audi- tory perception manifested itself in consciousness after an interval of time as a visual hallucination of the words. There was a reproduction of the original experience but not in its original form. It had undergone a secondary alteration by which the visual perception replaced the auditory perception. As a memory it was a conversion or translation of an auditory experience into terms of another sense. Now the conversion must have been effected by some mechanism outside of consciousness; that is to say, it was not an ordinary visualization, i. e., intensely vivid secondary images pertaining to a conscious memory, as when one thinks of the morn- ing's breakfast table and visualizes it; for there was no conscious memory of the words, or knowl- edge that there ever had been such an experience. The visualization therefore must have been induced by something not in the content of consciousness, something we have called a secondary process, of which the individual is unaware. We can conceive of the phenomenon originating in either one of two possible modes. Either the hallucination was a newly fabricated conscious ex- 92 THE UNCONSCIOUS perience; or it was a reproduction of secondary visual images originally belonging to the auditory perception at the time of its occurrence and now thrust into consciousness in an intensely vivid form. In either case, for this to have taken place some- thing must have been left by the original experience and conserved apart from and independent of the content of the personal consciousness at any and all moments something capable of functioning after an interval of time as a secondary process out- side of the personal consciousness. The only in- telligible explanation of the phenomenon is that the original auditory impression persisted, somehow and somewhere, in a form capable of conservation as a specific and independent residuum during all subsequent changes in the content of consciousness. This residuum either fabricated the hallucination or thrust its secondary images into consciousness to become the hallucination. The phenomenon by itself does not permit a con- clusion as to the nature of the residuum, whether it is psychological or neural ; i. e., whether an audi- tory perception, as perception, still persists sub- consciously outside the focus of awareness of consciousness, or whether it has left an alteration of some kind in the neurons. Whatever the inner na- ture of the conserved experience it obviously must have a very specific and independent existence, somehow and somewhere, outside of the awareness of consciousness, and one capable of secondary functioning in a way that can reproduce the orig- A RESIDUUM OF EXPERIENCES 93 inal experience in terms of another sense. In other words, conservation must be in the form of some kind of residuum, psychological or neural. It must be, therefore, something very different from reproduction or a recurrent phase of conscious- ness. Further, it must form a stage in the proc- ess of memory of which reproduction is the final result. This observation of course does not stand alone. I have cited a number of observations and might cite many more in which the same phenomenon of transformation or conversion of sensory images of one sense into images of another sense was promi- nent. Indeed a study of hallucinations, artificial or spontaneous, which are representations of former experiences and where the determining factors can be ascertained, will show that in most, if not all, of them this same mechanism of conversion is at work. Take, for instance, the experiment cited in our last lecture, the one in which Miss B. was directed to look into a crystal for the purpose of discovering the whereabouts of some money she had lost without being aware of the fact. In the crystal she sees a vision of herself walking along a particular street in Boston absorbed in thought. She sees herself in a moment of absent-mindedness take some bank- notes out of her pocket, tear them up, and throw them into the street. Now this artificial hallucination was, as we have seen, a picture of an actual occurrence for which there was amnesia. It must, therefore, have been 94 THE UNCONSCIOUS determined by that experience. The psychological phenomena manifested, however, were really much more complicated than would appear at first sight. An analysis of this vision, which unfolded itself like a cinematograph picture, would show that it was a composite visual representation of several different kinds of experiences of past perceptions of her body and face, of her conscious knowledge of her relation to the environment (in the street), of mus- cular movements, and of her knowledge derived from subconscious tactile impressions of the act. Of these last she was not aware at the time of their occurrence. Much of this knowledge must have persisted as a residuum of the original experience and functioned subconsciously. Thereby, perhaps, the original secondary visual images were repro- duced and emerged into consciousness as the hallu- cination or pictorial memory. Similar phenomena indicative of conservation being effected by means of a residuum of the orig- inal experience may be produced experimentally in various ways. For instance, in certain hysterics with anesthesia if you prick a number of times a part of the body say the hand in which all tactile sensation has been lost, and later direct the subject to look into a crystal, he will see a number, perhaps written on a hand. This number, let us say five, will correctly designate the number of times the hand was pricked. Now, because of the loss of sensibility, the subject was unaware of the pin-pricks. Never- theless, of course, they were recorded subcon- A RESIDUUM OF EXPERIENCES 95 sciously, coconsciously). Their subsequent trans- formation into a visual hallucination not only shows that they were conserved, but that they left some- thing which was capable of taking part, outside of consciousness, in a secondary process which gave rise to the hallucination. An examination of all crystal visions, so far as they are translated memories of actual experiences, will show this same evidence for a conserved resi- duum. That conservation is not merely a figure of speech to express the ability to determine the recurrence of a previous experience, but means a specific re- siduum capable of independent and elaborate func- tioning, is brought out more conspicuously in those visions which are elaborately fabricated symbol- isms of an antecedent experience. In other words, the vision is not a literal recurrence of a previous phase of consciousness, in that the latter has been worked over, so to speak, so as to appear in con- sciousness in a reconstructed form. Though recon- structed it either still retains its original meaning or is worked out to a completion of its thoughts, or to a fulfilment of the emotional strivings pertaining to them (anxieties, wishes, etc.). These visions, perhaps, more frequently occur spontaneously, often at moments of crises in a person's life, but also are observed under experimental conditions. Sometimes they answer the doubts, scruples and other problems which have troubled the subject, sometimes they express the imaginary fulfilment of 96 THE UNCONSCIOUS intense longings or of anxieties and dreads which have been entertained, or disturbing thoughts which have pricked the conscience.* We are obliged to conclude, in the light of experimental observations of the same class, that such phenomena are deter- mined by the specific residua of antecedent thoughts which must be conserved and function in a specific manner to appear in this metamorphosed form. Similar residual processes underlying post-hypnotic phe- nomena Conserved experiences which give rise to more complicated secondary elaboration may be observed in suggested post-hypnotic phenomena. Experiments of this kind may be varied in many ways. The phenomenon may be an hallucination similar to the one I have just described in hysterics, or a so-called subconscious calculation. You sug- gest in hypnosis to a suitable subject that he shall multiply certain numbers, or calculate the number of seconds intervening between certain hours let us say between 10 :43 and 5 :13 o 'clock the answer to be given in writing on a certain day. The subject is then awakened immediately, before he has time to do the calculation while in hypnosis. Later, if the experiment is successful, at the time designated the subject will absent-mindedly or auto- matically write the figures giving the answer. There are two modes in which these calculations may be accomplished. In a special and limited class of cases, where there is a large split-off subconscious * For specific instances, see Lecture VII, 97 personality, or doubling of consciousness, the cal- culation may be made entirely by this secondary subconscious self, in the same fashion as it would be made by the principal personality if the problem were given in the waking state. The subconscious personality will go through each conscious step in the calculation in the same way.* In a second class of cases the calculations are worked out, apparently, unconsciously, without participation in the process by a subconscious personality even when such exists. At most it would seem that isolated numbers repre- senting different steps in the calculation arise from time to time coconsciously as a limited secondary consciousness (of which the personal consciousness is unaware) until finally the figures of the com- pleted answer appear therein. The calculation it- self appears to be still another process outside both the personal and the secondary consciousness. When the problem has been finished the answer is finally given automatically. The whole process is too complicated to go into at this time before we have studied the problems of the coconscious.f It is enough to say that it plain that the hypnotic experience the suggested problem must be con- sidered as some kind of specific residuum, psy- chological or neural, and that this residuum must be one capable of quite elaborate independent and sub- conscious intellectual activity before finally becom- ing transformed into the final answer. * Morton Prince : Experimental Evidence for Coconscious Idea- tion, Journal of Abnormal Psychology, April-May, 1908. f For further details, see Lecture VI, p. 169. 98 THE UNCONSCIOUS Residual processes underlying dreams. When citing the evidence of dreams for the conservation of for- gotten experiences I spoke of one type of dream as a symbolical memory. I may now add it is more than this; it is a fabrication. The original experi- ence or thought may appear in the dream after being worked over into a fantasy, allegory, sym- bolism, or other product of imagination. Such a dream is not a recurrent phase of consciousness, but a newly fabricated phase. Further, analytical and experimental researches go to show that the fabri- cation is performed by the original phase without the latter recurring in the content of the personal consciousness. The original phase must therefore have been conserved in some form capable of such independent and specific functioning, i. e., fabrica- tion below the threshold of consciousness. For in- stance : The subject dreamed that she was standing where two roads separated. One was broad and bright and beautiful, and many people she knew were going that way. The other road was the rocky path, quite dark, and no one was going that way, but she had to go. And she said, "Oh, why must I go this way? Will no one go with me?" And a voice replied, "I will go with you." She looked around, and there were some tall black figures; they all had names across their foreheads in bright letters, and the one who spoke was Disappointment ; and all the others said, "We will go with you," and they were Sorrow, Loss, Pain, Fear, and Lone- liness, and she fell down on her face in anguish. Now an analysis of the antecedent thought of this subject and a knowledge of her circumstances and mental life, though we cannot go into them here, make it perfectly clear that as a fact, whether there A RESIDUUM OF EXPERIENCES 99 was any causal connection or not, this dream was a symbolic expression of those thoughts. The rocky path has been shown to be symbolic of her concep- tion of her own life entertained through years the other road symbolic of the life longed for and imagined as granted to others. Likewise the rest of the dream symbolized, in a way which any one can easily recognize, the lot which she had in her disappointment actually fancied was hers. The thoughts thus symbolized had been constantly recur- ring thoughts and therefore had been conserved. They were reproduced in the dream, not in their original form, but translated into symbols and an allegory. Something must, therefore, have effected the translation. In other words, the dream is not a recurrent phase of consciousness but an allegori- cal fabrication which expresses these thoughts, not literally as they originally occurred, but in the form of an imaginative story. Now the similarity of the allegorical dream thoughts to the original thoughts can be explained only in two ways: either as pure chance coincidence, or through a relation of cause and effect. In the latter case the dream might have been determined either by the specific antecedent thoughts in question those revealed as memories in the analysis, or both series might have been deter- mined by a third, as yet unrevealed, series. For the purposes of the present problem it is immaterial which so long as the dream was determined by some antecedent thought. The very great frequency, not to say universality, with which this same similarity 100 THE UNCONSCIOUS or a logical relation with antecedent thoughts is found in dreams after analysis renders chance coin- cidence very improbable. We must believe, there- fore, that the dream was determined by antecedent experiences. It is beyond my purpose to enter here into an exposition of the theory of the mechanism of dreams, although I shall touch upon it later in some detail in connection with subconscious proc- esses. We need here only concern ourselves with this mechanism so far as it bears upon the principle of conservation. Suffice it to say that analytical observations (Freud) have, it seems to me, conclu- sively shown that conserved experiences may be not only the determining factors in dreams, but that while in a state of conservation they are capable of undergoing elaborate fabrication and afterwards appearing so thoroughly transformed in conscious- ness as not to be superficially recognizable. I have also been able to reach the same conclusions by the method of experimental production of dreams. The only question is, in what form can a thought be so conserved that it can, while still in a state of conservation, without itself rising into conscious- ness, fabricate a symbolism, allegory, or other work requiring imagination and reasoning? The only logical and intelligible inference is that the antece- dent conscious experience has been either itself spe- cifically conserved as such outside of the personal consciousness, or has left some neural residuum or disposition capable of functioning and constructing the conscious dream fabrication. A RESIDUUM OF EXPERIENCES 101 Residual processes underlying physiological bodily dis- turbances Before proceeding further I would invite your attention to another class of facts as these facts must be taken into consideration in any theory of conservation. These facts show that the residua can, by subconscious functioning, induce physiologi- cal bodily manifestations without reproducing the original mental experience as conscious memory. In certain abnormal conditions of the nervous sys- tem, i. e., in certain psychoneuroses, we meet with certain involuntary actions of the limbs or muscles known as spasms and contractures ; also with cer- tain impairment of functions such as blindness, deafness, loss of sensation (anesthesia), paralysis, etc. These disturbances are purely functional, meaning that they are not due to any organic dis- ease. Now the evidence seems to be conclusive that these physiological disturbances are caused some- times by ideas after they have passed out of con- sciousness and become, as ideas, dormant, i. e., while they are in a state of conservation and have ceased to be ideas or, at least, ideas of which the subject is aware. A moment's consideration will convince you that this means that ideas, or, at least, expe- riences in a state of conservation, and without be- ing reproduced as conscious memory, can so func- tion as to affect the body in one or other of the ways I have mentioned. To do this they must exist in some specific form that is independent of the per- sonal consciousness of the moment. To take, for 102 THE UNCONSCIOUS example, an actual case which I have elsewhere described : B. C. A., in a dream, had a visual hallucination of a flash of light which revealed a scene in a cave and which was followed by blindness such as would physiologically follow a tremendous flash. In the dream she is warned that if she looks into the cave she will be blinded. She looks ; there is a blinding flash and loss of vision follows; after waking she was still partially blind, but she continued from time to time to see momentary flashes of light re- vealing certain of the objects seen in the dream in the cave, and these flashes would be succeeded tem- porarily by absolute blindness as in the dream. She had no memory of the dream. Now psychological analysis disclosed the meaning of the dream ; it was a symbolical representation of certain conserved (subconscious) previous thoughts thoughts appre- hensive of the future into which she dared not look, thinking she would be overwhelmed. While in a state of conservation the residua of these antece- dent thoughts had translated themselves into the symbolical hallucination of the dream and the loss of vision. Similarly after waking, although she had no memory of the dream, the conserved residua of the same thoughts continued to translate themselves into visual hallucinations and to induce blindness.* It would take too long for me to enter here into the * Prince : Mechanism and Interpretation of Dreams, Jour, of Abn. Psych., October-November, 1910. A RESIDUUM OF EXPERIENCES 103 details of the analysis which forces this conclusion.* Similarly, as is well known, convulsions resemb- ling epilepsy, paralysis, spasms, tics, contractures, etc., may be caused directly or indirectly by ideas, after they have passed out of consciousness and ceased to take part in the conscious processes of thought. At least that is the interpretation which the facts elicited by the various methods of investi- gation seem to require. There is an analogous class of phenomena which ought to be mentioned among the possible data bearing upon the theory of memory, although too much weight cannot be placed upon them as their interpretation is not wholly clear. I will discuss them in detail later in connection with the phenom- ena of the emotions. They are certain emotional phenomena which are attributed by some writers to ideas in a state of conservation. It has been demon- strated that ideas to which strong feeling tones are attached are accompanied by such physiological effects as disturbance of respiration, of the heart's action, of the vaso-motor system, of the secretions, etc., and also by certain galvanic phenomena which are due to the diminution of the electrical resist- * If, lacking this knowledge of the data, any one chooses to insist that it was not the conserved residua of previous thoughts, but of the dream itself (the only alternative entertainable explanation) which induced, after waking, the hallucinatory phenomena and blindness, we still fall back upon the same principle, namely, that of the subconscious functioning of conserved residua of a conscious experi- ence producing a physiological (and psychological) effect. 104 THE UNCONSCIOUS ance of the body, probably caused by increased secretion of sweat.* Now the point is that such phenomena are some- times experimentally obtained in connection with certain test words f spoken to the subject experi- mented upon, although he has no recollection of any incident in his life which could have given an emo- tional tone to the word and, therefore, can give no explanation of the physical reaction. By various technical methods, however, memories of a for- gotten emotional experience in which the idea (represented by the word) plays a part and through which it derived its emotional tone are resurrected. I have been able to obtain such reactions from test words which investigation showed referred to the incidents of terrifying dreams which were com- pletely forgotten in the waking state. When the test word was given, the subject might, for instance, exhibit a respiratory disturbance a sudden gasp without conscious knowledge of its significance, and the galvanometer, with which the subject was in circuit, would show a wide deflection. Eecovery of the dream in hypnosis would explain the meaning of the emotional disturbance excited by the word. The * According to recent researches of Sidis in conjunction with Kalmus, and later with Nelson (The Nature and Causation of the Galvanic Phenomenon, Psychological Beview, March, 1910) similar galvanic phenomena under similar conditions may be caused by the generation of an electric current within the body. f The test word (e. g., boat, stone, hat, etc.) of course represents an idea which may have various associations in the mind of the subject. A RESIDUUM OF EXPERIENCES 105 interpretation which has been put upon such phe- nomena is that the residua of the forgotten experi- ence are " struck" by the test word. As the for- gotten experience originally included the emotion and its physiological reaction, so the residua are linked by association to the emotional mechanism and when stimulated function as a subconscious process and excite the reaction. If this interpreta- tion, strongly held by some, be correct, the phe- nomena are important for the support they give to the theory of conservation. They would indicate that conscious experiences must be conserved in a very specific subconscious form, one that is ca- pable, without becoming conscious memory, of excit- ing the physiological apparatus of the emotions in a manner identical with that of conscious emotional ideas. They are open, however, to a simpler ex- planation, whether more probable or not: namely, that it is not the residua of the forgotten experi- ence which unconsciously excite the physiological reaction, but the auditory symbol, the test word itself. The symbol having been once associated with the emotional reaction, it afterwards of itself, through a short circuit so to speak, suffices to induce the reaction, though the origin of the association has been forgotten and, therefore, the subject is in entire ignorance of the reason for the strong feeling manifestation. On the other hand, in some instances test words associated with emotional experiences which originally were entirely coconscious and had never entered conscious awareness at all give the 106 THE UNCONSCIOUS reactions in question.* As coconscious memories of such experiences can be demonstrated it would seem at first sight as if under such conditions the word- reactions must come from a true subconscious proc- ess the subconscious memory. And yet even here it is difficult to eliminate absolutely the possibility of the second interpretation. There are, however, a large number of emotional phenomena occurring in pathological conditions which can only be intelligibly interpreted as being due to the residua of previously conscious experiences functioning as a subconscious process. These phenomena we shall have occasion to review in succeeding lectures. They are too com- plex to enter upon at this stage. Aside, then, from these word-reactions we have a sufficient number of other phenomena, such as I have cited, Tzhich indicate that conscious experi- ences when conserved must persist in a form ca- pable of exciting purely physiological reactions without the experiences themselves rising into con- sciousness again as memory. The form must also be one which permits of their functioning as intelli- gent processes although not within the conscious field of awareness of the moment. As a final summing up of the experiments and observations of the kind which I have thus far cited, * Morton Prince and Frederick Peterson : Experiments in Psycho- Galvanic Eeactions from Coconscious (Subconscious) Ideas in a Case of Multiple Personality, Journal of Abnormal Psychology, April- May, 1908. A RESIDUUM OF EXPERIENCES dealing with forgotten experiences, we may say that they lead us to the following conclusions : 1. That conservation is something very different from reproduction. 2. A given experience is conserved through the medium of some kind of residuum of that experi- ence. This residuum must have a specific existence independent of consciousness, in that it is capable of specific and independent functioning, coincidentally with and outside of the consciousness of any given moment. Its nature must be such that it can incite through specific processes the following phenomena in none of which the conscious processes of the mo- ment take part as factors : (a) Specific memory for the given experience expressed through the established physiological mechanisms of external expression (speech, writing, gestures) after the manner of a mnesic process. (b) A mnesic hallucination which is a represen- tation of the antecedent perceptual experience but after having undergone translation into terms of another sense. (c) A mnesic hallucination in which the original experience appears synthesized with various other experiences into an elaborate representation of a complex experience, or secondarily elaborated into a symbolism, allegory or other fabrication. (d) Mnesic phenomena which are a logical con- tinuation of the antecedent conscious experiences and such as ordinarily are produced by conscious processes of thought reasoning, imagination, voli- 108 THE UNCONSCIOUS tion (mathematical calculations, versification, fab- rication, etc.). (e) Physical phenomena (paralyses contrac- tures, vasomotor disturbances, etc.). In other words a specific experience while in a state of conservation and without being reproduced in consciousness can incite or induce processes which incite these and similar phenomena. LECTURE V NEUROGRAMS We have got as far as showing that the phenom- ena of memory to be intelligible require that ideas which have passed out of mind must be conserved through some sort of residuum left by the original experience. But this as a theory of memory is in- complete; the question remains, How, and in what form, manner, or way, are they conserved? In other words, What is the nature of the residuum? Is it psychical or physical? * As we have seen, from the fact that something outside of the personal consciousness can manifest memory of a given ex- perience at the very same moment when the per- sonal consciousness has amnesia for that experi- ence, we are compelled to infer that conservation must be by a medium, psychological or physiologi- cal, capable of being excited as a specific secondary process. Now this medium must be either an undiff erentiated * ' Psyche ' ' or specific differentiated residua. In the former case we postulate a concept of a transcendental something beyond experience * I use this term physical in the sense in which it is used in the physical sciences without reference to any metaphysical concept or the ultimate nature of matter or of a physical process. 109 110 THE UNCONSCIOUS and of which, like the soul after death, we have and can have no knowledge. To this concept of an Tin- differentiated Psyche we shall return presently. If the second alternative specific differentiated residua be the medium by which experiences are conserved, then the residua must be either specific psychological states, i. e., the original psychological experience itself as such; or neural residua (or dispositions) such as when excited are ordinarily correlated with a conscious memory. In either case the medium would be such as to permit of the experiences manifesting themselves, while so con- served outside of the personal consciousness, as a very specific secondary process, not only reproduc- ing the original experience as memory, but elabor- ating the same and exhibiting imagination, reason- ing, volition, feeling, etc. Unless the doctrine of the undifferentiated Psyche be accepted it is diffi- cult to conceive of any other mode in which conserv- ation can be effected so as to permit of the phe- nomena of memory outside of consciousness. Conservation considered as psychological residua. It is hypothetically possible that our thoughts and other mental experiences after they have passed out of mind, out of our awareness of the moment, may continue their psychological existence as such although we are not aware of them. Such an hypothesis derives support from the fact that re- searches of recent years in abnormal psychology have given convincing evidence that an idea, under NEUROGRAMS 111 certain conditions, after it has passed out of our awareness may still from time to time take on an- other sort of existence, one in which it still remains an idea, although our personal consciousness of the moment is not aware of it. A coconscious idea, it may be called. More than this, in absent-minded- ness, in states of abstraction, in artificial conditions as typified in automatic writing, and particularly in pathological conditions (hysteria), it has been fairly demonstrated, as I think we are entitled to assert, that coconscious ideas in the form of sensa- tions, perceptions, thoughts, even large systems of ideas, may function and pursue autonomous and contemporaneous activity outside of the various systems of ideas which make up the personal con- sciousness. It usually is not possible for the in- dividual to bring such ideas within the focus of his awareness. Therefore, there necessarily results a doubling of consciousness, two consciousnesses, one of which is the personal consciousness and the other a coconsciousness. These phenomena need to be studied by themselves. We shall consider them here only so far as they bear on the problem of conscious memory. Observation has shown that among ideas of this kind it often happens that many are memories, reproductions of ideas that once be- longed to the personal consciousness. Hence, on first thought, it seems plausible that conservation might be effected by the content of any moment's consciousness becoming coconscious after the ideas have passed out of awareness. According to such 112 THE UNCONSCIOUS an hypothesis all the conscious experiences of our lives, that are conserved, would form a great cocon- scious field where they would continue their exist- ence in specific form as ideas, and whence they could be drawn upon for use at any future time. Various difficulties are raised by this hypothesis. In the first place, there is no evidence that cocon- scious ideas have a continuous existence. The tech- nical methods of investigation which give evidence of such ideas functioning outside of the awareness of the personal consciousness do not show that at any given moment they are any more extensive than are those which fill the field of the personal con- sciousness. Indeed, usually, the coconscious field is of very limited extent. There remains an enor- mous field of conserved experiences to be accounted for. So far then as coconscious ideas can be dis- covered by our methods of investigation they are inadequate to account for the whole of the con- servation of life's experiences. In the second place, these ideas come and go in the same fashion as do those which make up the content of the main personal consciousness; and many are constantly recurring to become coconscious memories. The same problem, of the nature of conservation, therefore confronts us with cocon- scious ideas in the determination of the mechanism of coconscious memory. To explain conservation through coconscious ideas is but a shifting of the problem. If a broader concept be maintained, namely, that this coconsciousness, which can be NEUROGRAMS 113 demonstrated in special conditions, is but a fraction of the sum total of coconscious ideas outside of the personal awareness, we are confronted with a con- cept which from its philosophical nature deals with postulates beyond experience. We can neither prove nor disprove it. There is much that can be said in its support for the deeper we dive into the subconscious regions of the mind the more exten- sively do we come across evidences of coconscious states underlying specific phenomena. Neverthe- less, the demonstration of coconscious states in any number of specific phenomena does not touch the problem of the nature of conservation. In weighing the probability of the hypothesis on theoretical grounds it would seem, as I have already said in a preceding lecture, to be hardly conceivable that ideas that had passed out of mind, the thoughts of the moment of which we are no longer aware, can be treasured, conserved as such in a sort of psycho- logical storehouse or reservoir of consciousness, just as if they were static or material facts. Such a conception would require that every specific state of consciousness, every idea, every thought, per- ception, sensation and feeling, after it had passed out of mind for the moment, should enter a great sea of ideas which would be the sum total of all our past experiences. In this sum-total millions of ideas would have to be conserved in concrete form until wanted again for use by the personal con- sciousness of the moment. Here would be found, in what you will see at once would be a real subcon- 114 THE UNCONSCIOUS scious mind beyond the content or confines of our awareness, stored up, so to speak, ready for future use, the mass of our past mental experiences. Here you would find, perhaps, the visualized idea of a seagull soaring over the waters of your beautiful bay conserved in association with the idea of the mathematical formula, a+b=c; the one having originated in a perception of the outer world through the window of your study while you were working at a lesson in algebra which gave rise to the latter. And yet conserved as ideas, as such vast numbers of experiences would be, we should not be aware of them until they were brought by some mysterious agency into the consciousness of the mo- ment. The great mass of the mental experiences of our lives which we have at our command, our extensive educational and other acquisitions from which we consciously borrow from time to time, as well as those which, we have seen, are conserved though they cannot be voluntarily reproduced, all these mental experiences, by the hypothesis, would still have persisting conscious existences in their original concrete psychological form. Such an hypothesis, to my mind, is hardly think- able, and yet this very hypothesis has been pro- posed, though in less concrete form perhaps, in the doctrine of the "subliminal mind," a particular form of the theory of the subconscious mind. This doctrine, which we owe to the genius of the late W. H. H. Meyers, has more recently appeared, without full recognition of its paternity, in the NEUROGRAMS 115 writings of a more modern school of psychology. According to this doctrine our personal conscious- ness, the ideas which we have at any given moment and of which we are aware, are but a small portion of the sum total of our consciousness. Of this sum- total we are aware, at any given moment, of only a fractional portion. Our personal consciousness is but sort of up-rushes from this great sum of con- scious states which have been called the subliminal mind, the subliminal self, the subconscious self. These conscious up-rushes make up the personal "I," with the sense of awareness for their content. The facts to be explained do not require such a metaphysical hypothesis. All that is required is that our continuously occurring experiences should be conserved in a form, and by an arrangement, which will allow the concrete ideas belonging to them to reappear in consciousness whenever the conserved arrangement is again stimulated. This requirement, the theory of conservation, which is generally accepted by those who approach the prob- lem by psycho-physiological methods, fully satisfies. Before stating this theory in specific form let me mention to you still another variety of the sublim- inal hypothesis, metaphysical in its nature, which appeals to some minds of a philosophical tendency. Conservation considered as an undifferentiated psychical something or "psyche." It is difficult to state this hy- pothesis clearly and precisely for it is necessarily vague, transcending as it does human experience. 116 THE UNCONSCIOUS It is conceived, as I understand the matter, or at least the hypothesis connotes, that ideas of the moment, after ceasing to be a part of awareness, subside and become merged in some form or other in a larger mind or consciousness of which they were momen- tary concrete manifestations or phases. This con- sciousness is conceived as a sort of unity. Ideas out of awareness still persist as consciousness in some form though not necessarily as specific ideas. According to this hypothesis, it is evident that when the ideas of the moment's awareness subside and become merged into the larger consciousness either one of two things must happen ; they must either be conserved as specific ideas, or lose their individu- ality as states of consciousness, and become fused in this larger consciousness as an undifferentiated psychical something. Some like to call it a ' ' psyche, ' ' apparently finding that by using a Greek term, or a more abstract expression, they avoid the difficulties of clear thinking. The first alternative is equivalent to the hypothe- sis of conservation in the form of coconscious spe- cific ideas which we have just discussed. The second alternative still leaves unexplained the mechanism by which differentiation again takes place in this psychical unity, how a conscious unity becomes dif- ferentiated again into and makes up the various phases (ideas) of consciousness at each moment; that is, the mechanism of memory. But, aside from this difficulty, the hypothesis is opposed by evidence which we have already found NEUROGRAMS 117 for the persistence of ideas (after cessation as states of consciousness) in some concrete form ca- pable of very specific activity and of producing very specific effects. We have seen that such ideas may under certain conditions continue to manifest the same specific functionating activity as if continuing their existence in concrete form (e. g., so-called sub- conscious solution of problems, physiological dis- turbances, etc.). This phenomenon is scarcely reconcilable with the hypothesis that ideas after passing out of awareness lose their concrete spe- cificity and become merged into an undifferentiated psychical something.* Furthermore, for a concept transcending experi- ence to be acceptable it must be shown that it ade- quately explains all the known facts, is incompatible with none, and that the facts are not intelligible on any other known principle. These conditions seem to me far from having been fulfilled. Before accept- ing such a concept it is desirable to see if conserva- tion cannot be brought under some principle within the domain of experience. Conservation considered as physical residua.

The desire to explain a secondary con- sciousness by this doctrine has probably given rise to the popular notion of two souls in a single body! 118 THE UNCONSCIOUS nervation, and reproduction occur postulates the conserved residua as physical in nature. Whenever we have a mental experience of any kind a thought, or perception of the environment, or feeling some change, some "trace," is left in the neurons of the brain. I need not here discuss the relation be- tween brain activity and mind activity. It is enough to remind you that, whatever view be held, it is universally accepted that every mental process is accompanied by a physical process in the brain; that, parallel with every series of thoughts, percep- tions, or feelings, there goes a series of physical changes of some kind in the brain neurons. And, conversely, whenever this same series of physical changes occurs the corresponding series of mental processes, that is, of states of consciousness, arises. In other words, physical brain processes or expe- riences are correlated with corresponding mind processes or experiences, and vice versa.* This is known as the doctrine of psycho-physical parallel- ism. Upon this doctrine the whole of psycho-physi- ology and psycho-pathology rests. Mental physi- ology, cerebral localization, and mental diseases * If the theory of the unconscious presented in these lectures be firmly established this doctrine will have to be modified to this ex- tent, that, while all mental processes are accompanied by brain processes, brain processes that ordinarily have conscious equivalents can within certain limits occur without them and exhibit all the characteristics of intelligence unconscious cerebration. Indeed, it becomes probable that every mental process is a part of a larger mechanism in which unconscious brain processes not correlated with the specifically conscious processes are integral factors. NEUROGRAMS 119 excepting on its assumption are unintelligible in- deed, the brain as the organ of the mind becomes meaningless. We need not here inquire into the na- ture of the parallelism, whether it is of the nature of dualism, e. g., a parallelism of two different kinds of facts, one psychical and the other physical; or whether it is a monism, i. e., a parallelism of two different aspects of one and the same fact or a parallelism of a single reality (mind) with a mode of apprehending it (matter) mind and matter in their inner nature being held to be practically one and the same. The theory of memory is unaffected whichever view of the mind-brain relation be held. Now, according to the psycho-physiological theory of memory, with every passing state of con- scious experience, with every idea, thought, or per- ception, the brain process that goes along with it leaves some trace, some residue of itself, within the neurons and in the functional arrangements be- tween them. It is an accepted principle of physi- ology that when a number of neurons, involved, let us say, in a coordinated sensori-motor act, are stim- ulated into functional activity they become so asso- ciated and the paths between them become so opened or, as it were, sensitized, that a disposition becomes established for the whole group, or a num- ber of different groups, to function together and reproduce the original reaction when either one or the other is afterward stimulated into activity. This "disposition" is spoken of in physiological lan- guage as a lowering of the threshold of excitability 120 THE UNCONSCIOUS a term which does not explain but only describes the fact. For an explanation we must look to the nature of the physical change that is wrought in the neurons by the initial functioning. This change we may speak of as a residuum. Similarly a system of brain neurons, which in any experience is correlated in activity with conscious experience, becomes, so to speak, sensitized and ac- quires, in consequence, a "disposition" to function again as a system (lowering of thresholds'?) in a like fashion; so that when one element in the sys- tem is again stimulated it reproduces the whole original brain process, and with this reproduction (according to the doctrine of psycho-physical par- allelism) there is a reproduction of the original conscious experience. In other words, without bind- ing ourselves down to absolute precision of lan- guage, it is sufficiently accurate to say that every mental experience leaves behind a residue, or a trace, of the physical brain process in the chain of brain neurons. This residue is the physical regis- ter of the mental experience. This physical register may be conserved or not. If it is conserved we have the requisite condition for memory; the form in which our mental experiences are conserved. But it is not until these physical registers are stimulated and the original brain experience is reproduced that we have memory. If this occurs the reproduc- tion of the brain experience reproduces the con- scious experience, i. e., conscious memory (accord- ing to whatever theory of parallelism is main- NEUROGRAMS 121 tained). Thus in all ideation, in every process of thought, the record of the conscious stream may be registered and conserved in the correlated neural process. Consequently, the neurons in retaining residua of the original process become, to a greater or less degree, organized into a functioning system corresponding to the system of ideas of the original mental process and capable of reproducing it. When we reproduce the original ideas in the form of memories it is because there is a reproduction of the physiological neural process. It is important to note that just as, on the psy- chological side, memory always involves the awak- ening of a previous conscious experience by an associated idea, one that was an element in the previous system of associated sensations, percep- tions, thoughts, etc., making up the experience, so, on the physiological side, we must suppose that it involves stimulation of the whole system of neu- rons belonging to this experience by the physiologi- cal stimulus corresponding to the conscious ele- ment or stimulus. For instance, if I see my friend A, the image is not a memory, though it is one I have had many times before and has left residua of itself capable of being reproduced as memory. But if I see his hat, and immediately previously linked pictorial images of him arise in my mind; or, if, when I see him, there arise images of his library in which I have previously seen him, these images are memory. A conscious memory is always the re- production of an experience by an associated idea. 122 THE UNCONSCIOUS or other element of experience (conscious or sub- conscious). Similarly we must infer that the neurons correlated with any past mental experience are stimulated by associated neuron processes. This is the foundation-stone of mental physiology; for upon the general principle of the correlation of mental processes with neural processes rests the whole of cerebral localization and brain physiology. Although we assume newly arranged dynamic associations of neurons corresponding to associa- tions of ideas, we do not know how this rearrange- ment is brought about, though we may conceive of it as following the physiological laws of lowering of thresholds of excitability. Nor do we know whether the modifications left as residua (by which the thresholds are lowered) are physical or chemical in their nature, though there is some reason for believ- ing they may be chemical. Chemical and physical theories of residua It is pos- sible that, through chemical changes of some kind left in the system of neurons corresponding to an experience, the neurons may become sensitized so as to react again as a whole to a second stimulus applied to one element. In other words a hyper- susceptibility may become established. There is a physiological phenomenon, known as anaphylaxis, which may possibly prove more than analogous, in that it depends upon the production, through chemical changes, of hyper-susceptibility to a stimu- lus which before was inert. The phenomenon is NEUROGRAMS 123 one of sensitizing the body to certain previously innocuous substances. If, for instance, a serum from a horse be injected into a guinea pig no ob- servable reaction follows. But, if a second dose be injected, a very pronounced reaction follows and the animal dies with striking manifestations called anaphylactic shock. This consists of spasm of the bronchioles of the lungs induced by contraction of their unstriated muscles and results in an attack of asphyxia.* The mechanism of anaphylaxis is a very compli- cated one involving the production in the blood of chemical substances called antibodies, and is far from being thoroughly understood. One theory is that sensitization consists in the "fixing" of the cells of the tissues with these antibodies. This may or may not be correct probably not and I am far from wishing to imply that sensitization of the neurons, as a consequence of functioning, has any- thing in common with the mechanism of sensitizing the body in anaphylaxis. I merely wish to point out that sensitizing nervous tissue through chemi- cal changes is a physiological concept quite within the bounds of possibility; and, as all functioning is probably accompanied by metabolic (chemical) changes, such metabolic changes may well persist in neurons after brain reactions produce sensitization. * Dr. S. J. Meltzer has pointed out in a very suggestive article (Journal American Medical Association, Vol. IV, No. 12) that the anaphylactic attack resembles that of bronchial asthma in man, and argues that this latter disease may be the same phenomenon, 124 THE UNCONSCIOUS If this hypothesis of sensitization should be proven it would offer an intelligible mechanism of the phenomenon of memory. If the system of neu- rons engaged in any conscious experience were sensitized by chemical changes it would acquire a hyper-susceptibility. The system as a whole would consequently be excited into activity by any other functioning system of neurons with which it was in anatomical association and might reproduce the originally correlated conscious experience. Various theories based on known or theoretical chemical or physical alterations in the neurons have been proposed to account for memory on the physi- ological side. Robertson * has proposed that it is of the nature of autocatalysis. Catalysis is the property possessed by certain bodies called cata- lyzers of initiating or accelerating chemical reactions which would take place without the catalyzer, but more slowly. "A catalyzer is a stimulus which ex- cites a transformation of energy. The catalyzer plays the same role in a chemical transformation as does the minimal exciting force which sets free the accumulation of potential energy previous to its transformation into kinetic energy. A catalyzer is the friction of the match which sets free the chemical energy of the powder magazine. ' ' f Numerous examples of catalytic actions might * T.

The inversion of sugar by acids, the decomposition of hydrogen peroxide by platinum black, fermentation by means of a solu- ble ferment or diastase, a phenomenon which may almost be called vital, are all instances. According to Leduc "the action of pepsin, of the pancreatic ferment, of zymase and other similar ferments has a great analogy with the purely physical phenome- non of catalysis." In auto-catalysis one of the products of the reac- tion acts as the catalyzer. Now Robertson con- cluded, as a result of his experiments carried out on frogs, that the processes which accompany the excitation of the cells of the neurons are of the nature of catalysis; for he found that they have as one eif ect the production of an acid ; and he also found that acids accelerate such processes which he concludes to be probably of the nature of oxida- tions. "The chemical phenomena which constitute the activity of a neuron cell," he says, "seem to us then an auto-catalytic oxidation, that is to say, an oxidation in which one of the products of the reaction acts as a catalyzer in the reaction." It occurred to him then that the physiological corre- late of memory might be explained on the principle of auto-catalysis. When, to test this hypothesis, he came to compare the results of certain psychological experiments on memory, made by two different ex- perimenters (Ebbinghaus and Smith), with the law characteristic of auto-catalytic chemical reactions, he found that they corresponded in a surprisingly 126 THE UNCONSCIOUS close way with this law. That is to say, assuming the value of the residua of memory (measured by the number of syllables learnt by heart) to be pro- portional to the mass of the chemical product of auto-catalysis, we should expect that the increase of the number of syllables or other experiences re- tained by memory following increase of repetitions would obey the law of catalytic reaction as ex- pressed in the mathematical formula established for the reaction. Now, as a fact, he found that the number of syllables that should be so retained in memory, as calculated theoretically by the formula, corresponded in a remarkable way with the actual number determined by experiment. "The agree- ment was closer," the author states, "than that which generally obtained in experiments in chemical dynamics carried out in vitro." Robertson sums up his conclusions as follows : "5th: We have shown that the phenomenon of which the subjective aspect is called 'memory' is of a nature indicating that the autocatalyzed chemi- cal reactions form the mechanism conditioning the response of the central nervous system to stimuli. "6th. In admitting that the extent of the trace of memory may be proportionate to the mass of a product of an autocatalyzed chemical reaction un- folding itself in the central nervous system as the result of the application of a stimulus, we have shown that the relation which one theoretically de- duces between the mass of memory material and NEUROGRAMS 127 the number of repetitions corresponds to that which has been found by experience. * ' 7th. On the basis of the hypothesis above men- tioned we have shown that the law of Weber- Fechner admits of a rational physico-chemical in- terpretation, and that the result thus obtained, pro- vided the hypothesis above mentioned be an exact representation of facts, is that the intensity of the sensation is at each instant proportionate to the mass of the product of the autocatalyzed chemical reaction above mentioned and, consequently, to the extent of the trace of memory. ' ' While it is easy to understand that auto-catalysis may take part in the chemical process which under- lies the performance of simple volition, as inferred by Robertson,* and perhaps reproduction in the memory process, it is difficult to understand how such a chemical action can explain conservation. The problem is not that of acceleration of an action, but of something like the storing up of energy. Rignanof has proposed an hypothesis according to which the cells of the nervous system are to be con- sidered as so many accumulators, analogous to elec- tric accumulators or storage batteries. "The simi- larities and differences which nerve currents pre- sent in comparison with electric currents warrant us in assuming in nerve currents some of the prop- * Further studies in the chemical dynamics of the central ner- vous system, Folio Neuro-Biologica, Bd.

Open Court Publish- ing Co., 1911. 128 THE UNCONSCIOUS erties of electric currents, and in attributing at the same time to the first other properties which the electric do not possess, provided these qualities are not incompatible with the others. ' ' Now, according to the hypothesis, the specific nervous current set up by any stimulus forms and deposits in the nucleus of the cells (through which the current flows) a substance which adds itself to the others already there without changing them and which is capable, under appropriate conditions, of being discharged and restoring the same specific current by which it was produced. Each cell thus becomes what Rignano calls an elementary nervous accumulator. He points out that ''both the concep- tion of accumulators of nervous energy in tension, and that of accumulators of a specific nervous en- ergy constituting their specific irritability," which the hypothesis includes, are not new but "an ordi- nary conception very generally employed." . . . "The only new thing which the above definition in- cludes is the hypothesis that the substance, which is thus capable of giving as a discharge a given nerv- ous current, was produced and deposited only by a nervous current of the same specificity, but in the inverse direction, and could have been produced and deposited only by such a current." "In just this capacity of restoring again the same specificity of nervous current as that by which each element had been deposited one would look for the cause of the mnemonic faculty, in the widest sense, which all liv- ing matter possesses. And further the very essence NEUROGRAMS 129 of the mnemonic faculty would consist entirely in this restitution." "The specific elementary accumulators (previ- ously termed specific potential elements) are thus susceptible now of receiving a third name, namely, that of mnemonic elements." "The preservation of memories is to be ascribed to the accumulations of substance," while "the reawakening of these memories consists in the restitution of the same cur- rents [by discharge of the substance] as had formerly constituted the actual sensation or impression." By this hypothesis Bignano explains not only memory but the inheritance of acquired characters and the whole process of specialization of cells, all of which phenomena are special instances of such elementary accumulators of organic energy being formed and discharged. Any attempt, with our present knowledge, to pos- tulate particular kinds of chemical or physical changes in the nervous system as the theoretical residua of physiological dispositions left by psycho- logical experiences must necessarily be speculative. And any hypothesis can only have so much validity as may come from its capability of explaining the known facts. It is interesting, however, to note some of the directions which attempts have taken to find a solution of the problem. For the present it is best to rest content with the theory to which we have been led, step by step, in our exposition, namely, that conservation is effected by some sort of physiological residua. This theory, of course, is 130 THE UNCONSCIOUS an old one, and has been expressed by many writers. What we want, however, is not expressions of opin- ion but facts supporting them. It would seem as if the facts accumulated in recent years by experi- mental and abnormal psychology all tended to strengthen the theory, notwithstanding an inclina- tion in certain directions to seek a psychological in- terpretation of conservation. Some minds of a certain philosophical bent will not be able to get over the difficulty of conceiving how a psychological process can be conserved by the physical residuum of a physiological process. But this is only the old difficulty involved in the problem of the relation between mind and brain of which conservation is only a special example. That a mind process and a brain process are so intimately related that either one determines the other there is no question. It is assumed in every question of psycho-physiology. The only question is the How. I may point out in passing, but without discussion, that if we adopt the doctrine of panpsychism for which I have elsewhere argued * namely, that there is only one process the mental in one and the same individual, and that what we know as the phys- ical process is only the mode of apprehending the mental process by another individual; if we adopt this doctrine of monism the difficulty is solved. In other words, the psychical (and consciousness) is * Prince: The Nature of Mind and Human Automatism, 1885: Hughlings-Jackson on the Connection between the Mind and Brain, Brain, p. 250, 1891; The Identification of Mind and Matter, Philosoph.

According to this view in their last analysis all physical facts are psychical in na- ture, although not psychological (for psychological means consciousness), so that physiological and psychical are one. To this point I shall return in another lecture. Neurograms. Whatever may be the exact nature of the theoretical alterations left in the brain by life 's experiences they have received various generic terms; more commonly " brain residua," and "brain dispositions." I have been in the habit of using the term neurograms to characterize these brain records. Just as telegram, Marconigram, and phonogram precisely characterize the form in which the physical phenomena which correspond to our (verbally or scripturally expressed) thoughts, are recorded and conserved, so neurogram precisely characterizes my conception of the form in which a system of brain processes corresponding to thoughts and other mental experiences is recorded and conserved.* *Kichard Semon (Die Mneme, 1908) has adopted the term Engramm with much the same signification that I have given to Neurogram, excepting that Engramm has a much wider meaning and connotation. It is not limited to nervous tissue, but includes the residual changes held by some to be left in all irritable living substances after stimulation. All such substances are therefore capable of memory in a wide sense (Mneme). 132 THE UNCONSCIOUS Of course it must not be overlooked that such neurograms are pure theoretical conceptions, and have never been demonstrated by objective methods of physical research. They stand in exactly the same position as the atoms and molecules and ions and electrons of physics and chemistry, and the "antibodies" and " complements " of bacteriology. No one has seen any of these postulates of science. They are only inferred. All are theoretical con- cepts; but they are necessary concepts if the phe- nomena of physical, chemical, and bacteriological science are to be intelligible. The same may be said for brain changes if the phenomena of brain and mind are to be intelligible. And so it happens that though our ideas pass out of mind, are forgotten for the moment, and become dormant, their physiological records still remain, as sort of vestigia, much as the records of our spoken thoughts are recorded on the moving wax cylinder of the phonograph. When the cylinder revolves again the thoughts once more are reproduced as auditory language. A better analogy would be the recording and reproducing of our thoughts by the dynamic magnetization of the iron wire in another type of the instrument. The vibration of the voice by means of a particular electrical mechanism leaves dynamic traces in the form of corresponding magnetic changes in the passing wire, and when the magnetized wire again is passed before the repro- ducing diaphragm the spoken thoughts are again re- produced. So, when the ideas of any given con- NEUROGRAMS 133 scious experience become dormant, the physiologi- cal records, or dynamic rearrangements, still re- main organized as physiological unconscious com- plexes, and, with the excitation of these physiologi- cal complexes, the corresponding psychological memories awake. It is only as such physiological complexes that ideas that have become dormant can be regarded as still existing. If our knowledge were deep enough, if by any technical method we could determine the exact character of the modifications of the disposi- tions of the neurons that remain as vestiges of thought and could decipher their meaning, we could theoretically read in our brains the record of our lives, as if graphically inscribed on a tablet. As Bibot has well expressed it: " . . . Feelings, ideas, and intellectual actions in general are not fixed and only become a portion of memory when there are corresponding residua in the nervous system re- sidua consisting, as we have previously demon- strated, of nervous elements, and dynamic associa- tions among those elements. On this condition, and this only, can there be conservation and reproduc- tion." Dormant ideas are thus equivalent to con- served physiological complexes. We may use either term to express the fact. The observations and experiments I have recited have led us to the conclusion that conservation of an experience is something quite specific and dis- * Th. Eibot : Diseases of Memory, pp. 154, 155. Translation by William Huntington Smith. D. Appleton & Co. 134 THE UNCONSCIOUS tinct from the reproduction of it. They compel us to the conclusion that we are entitled, as I pointed out at the opening of these lectures, to regard memory as a process and the result of at least two factors conservation and reproduction. But as conservation is meaningless unless there is some- thing to be conserved, w T e must also assume regis- tration; that is, that every conserved mental experi- ence is primarily registered somehow and some- where. Conservation implies registration. Such is the theory of memory as a process of reg- istration, conservation, and reproduction. Thus it will be seen (according to the theory) that ideas which have passed out of mind are preserved, if at all, not as ideas, but as physical alterations or rec- ords in the brain neurons and in the functional dynamic arrangements between them. From this you will easily understand that while, as you have seen from concrete observations, we can have conservation of experiences without mem- ory (reproduction) we cannot have memory without conservation. Three factors are essential for mem- ory, and memory may fail from the failure of any one of them. Unless an experience is registered in some form there will be nothing to preserve, and memory will fail because of lack of registration. If the experience has been registered, memory may fail, owing to the registration having faded out, so to speak, either with time or from some other rea- son; that is, nothing having been conserved, noth- ing can be reproduced. Finally, though an experi- NEUROGRAMS 135 ence has been registered and conserved, memory may still fail, owing to failure of reproduction. The neurographic records must be made active once more, stimulated into an active process, in order that the original experience may be recalled, i.-e., reproduced. Thus what we call conscious memory is the final result of a process involving the three factors, registration, conservation, and reproduction. Physiological memory. Memory as commonly re- garded and known to psychology is a conscious manifestation but, plainly, if we regard it, as we have thus far, as a process, then, logically, we are entitled to regard any process which consists of the three factors, registration, conservation, and repro- duction of experiences, as memory, whether the final result be the reproduction of a conscious expe- rience, or one to which no consciousness was ever attached. In other words, theoretically it is quite possible that acquired physiological body-experien- ces may be reproduced by exactly the same process as conscious experiences, and their reproduction would be entitled to be regarded as memory quite as much as if the experience were one of consciousness. In principle it is evident that it is entirely imma- terial whether that which is reproduced is a con- scious or an unconscious experience so long as the mechanism of the process is the same. Now, as a matter of fact, there are a large number of acquired physiological body-actions which, though unconscious, must be regarded quite as much 136 THE UNCONSCIOUS as manifestations of memory as is the conscious repetition of the alphabet, or any other conscious acquisition. Having been acquired they are ipso facto reproductions of organized experiences. We all know very well that movements acquired voli- tionally, and perhaps laboriously, are, after con- stant repetition, reproduced with precision with- out conscious guidance. They are said to be automatic; even the guiding afferent impressions do not enter the content of consciousness. The maintaining of the body in one position, sitting or standing, though requiring a complicated correlation of a large number of mus- cles, is carried out without conscious volition. It is the same with walking and running. Still more complicated movements are similarly performed in knitting, typewriting and playing the piano, shav- ing, buttoning a coat, etc. We do not even know the elementary movements involved in the action, and must become aware of them by observation. The neurons remember, i. e., conserve and reproduce the process acquired by previous conscious experiences. But though it is memory it is not conscious mem- ory, it is unconscious memory, i. e., a physiological memory. The acquired dispositions repeat them- selves what is called habit. Precision in games of skill largely depend upon this principle. A tennis player must learn the "stroke" to play the game well. This means that the muscles must be co- ordinated to a delicate adjustment which, once learned, must be unconsciously remembered and NEUROGRAMS 137 used, without consciously adjusting the muscles each time the ball is hit. Indeed some organic mem- ories are so tenacious that a player once having learned the stroke finds great difficulty even by ef- fort of will in unlearning it and making his muscles play a different style of stroke. Likewise one who has learned to use his arms in sparring by one method finds difficulty in learning to spar by an- other method. In fact almost any acquired move- ment is compounded of elementary movements which by repetition were linked and finely adjusted to produce the resultant movement, and finally con- served as an unconscious physiological arrange- ment. As one writer has said, the neuron organi- zation "faithfully preserves the records of proc- esses often performed." In what has just been said the fact has not been overlooked that the initiation or modification of any of the movements which have been classed as physi- ological memory (knitting, typewriting, games of skill, etc.), even after their acquisition, is necessar- ily voluntary and therefore, so far, a conscious mem- ory, but the nice coordination of afferent and effer- ent impulses for the adjustment of the muscles in- volved becomes, by repetition, an unconscious mech- anism, and is performed outside the province of the will as an act of unconscious memory. By repeated experience the neurons become functionally orga- nized in such a way as to acquire and conserve a functional "disposition" to reproduce the move- ments originally initiated by volition. 138 THE UNCONSCIOUS Physiological memory has indeed, as it seems, been recently experimentally demonstrated by Roth- mann, who educated a dog from which the hemi- spheres had been removed to perform certain tricks ; e. g., to jump over a hurdle.* Still another variety of memory is psycho-physio- logical. This type is characterized by a combina- tion of psychological and physiological elements and is important, as we shall see later, because of the conspicuous part which such memories play in pathological conditions. Certain bodily reactions which are purely physiological, such as vaso-motor, cardiac, respiratory, intestinal, digestive, etc., dis- turbances, become, as the result of certain experi- ences, linked with one or another psychical ele- ment (sensations, perceptions, thoughts), and, this linking becoming conserved as a "disposition," the physiological reaction is reproduced whenever the psychical element is introduced into consciousness. Thus, for example, the perception or thought of a certain person may become, as the result of a given social episode, so linked with blushing or cardiac palpitation that whenever the former is thrust into consciousness, no matter how changed the condi- tions may be from those of the original episode, the physiological reaction of the blood vessels or heart is reproduced. Here the original psycho-physio- logical experience the association of an idea (or psychical element) with the physiological process is conserved and repoduced. Such a reproduction is * Cf . Lecture VIII, p. 238. NEUROGRAMS 139 essentially a psycho-physiological memory depend- ing wholly upon the acquired disposition of the neu- rons.* Thus, to take an actual example from real life, a certain person during a series of years was expect- ing to hear bad news because of the illness of a member of the family and consequently was always startled, and her "heart always jumped into her throat," whenever the telephone rang. Finally the news came. That anxiety is long past, but now when the telephone rings, although she is not ex- pecting bad news and no thought of the original ex- perience consciously arises in her mind, her " heart always gives a leap and sometimes she bursts into a perspiration. ' ' A beautiful illustration of this type of memory is to be found in the results of the extremely impor- tant experiments, for psychology as well as physiol- ogy, of Pawlow and his co-workers in the reflex stim- ulation of saliva in dogs. These experiments show the possibility of linking a physiological process to a psychological process by education, and through the conservation of the association reproducing the physiological process as an act of unconscious mem- ory. (The experiments, of course, were undertaken for an entirely different purpose, namely, that of studying the digestive processes only.) It should be explained that it was shown that the salivary * Emotion is a factor in the genesis of such phenomena, but may be disregarded for the present until we have studied the phenomena of the emotions by themselves. 140 THE UNCONSCIOUS glands are selective in their reaction to stimuli in that they do not respond at all to some (pebbles, snow), but respond to others with a thin watery fluid containing mere traces of mucin or a slimy mucin-holding fluid, according as to whether the stimulating substance is one which the dog rejects, and which therefore must be washed out or diluted (sands, acids, bitter and caustic substances), or is an eatable substance and must as a food bolus be lubricated for the facilitation of its descent. Dry- ness of the food, too, largely determined the quan- tity of the saliva. Now the experiments of the St. Petersburg labo- ratory brought out another fact which is of particu- lar interest for us and which is thus described by Pawlow. "In the course of our experiments it ap- peared that all the phenomena of adaptation which we saw in the salivary glands under physiological conditions, such, for instance, as the introduction of the stimulating substances into the buccal cavity, reappeared in exactly the same manner under the influence of psychological conditions that is to say, when we merely drew the animal's attention to the substances in question. Thus, when we pretended to throw pebbles into the dog's mouth, or to cast in sand, or to pour in something disagreeable, or, fi- nally, when we offered it this or that kind of food, a secretion either immediately appeared or it did not appear, in accordance with the properties of the substance which we had previously seen to regu- late the quantity and nature of the juice when NEUROGRAMS 141 physiologically excited to flow. If we pretended to throw in sand a watery saliva escaped from the mucous glands; if food, a slimy saliva. And if the food was dry for example, dry bread a large quantity of saliva flowed out even when it excited no special interest on the part of the dog. When, on the other hand, a moist food was presented for ex- ample, flesh much less saliva appeared than in the previous case however eagerly the dog may have desired the food. This latter effect is particularly obvious in the case of the parotid gland." It is obvious that in these experiments, when the experimenter pretended to throw various sub- stances into the dog's mouth, the action was effec- tive in producing the flow of saliva of specific quali- ties because, through repeated experiences, the pic- torial images (or ideas) of the substance had be- come associated with the specific physiological sali- vary reaction, and this association had been con- served as a neurogram. Consequently the neuro- graphic residue when stimulated each time by the pretended action of the experimenter reproduced reflexly the specific physiological reaction and, so far as the process was one of registration, conserva- tion, and reproduction, it was an act of psycho- physiological memory. That this is the correct interpretation of the edu- cational mechanism is made still more evident by other results that were obtained; for it was found * The Work of the Digestive Glands (English Translation), p. 152. 142 THE UNCONSCIOUS that the effective psychical stimulus may be part of wider experiences or a complex of ideas; every- thing that has been in any way psychologically as- sociated with an object which physiologically ex- cites the saliva reflex may also produce it; the plate which customarily contains the food, the furniture upon which it stands; the person who brings it; even the sound of the voice and the sound of the steps of this person.* Indeed, it was found that any sensory stimulus could be educated into one that would induce the flow of saliva, if the stimulus had been previously associated with food which normally excited the flow. "Any ocular stimulus, any desired sound, any odor that might be selected, and the stimulation of any part of the skin, either by mechanical means or by the application of heat or cold, have in our hands never failed to stimulate the salivary glands, al- though they were all of them at one time supposed to be inefficient for such a purpose. This was ac- complished by applying these stimuli simultane- ously with the action of the salivary glands, this ac- tion having been evolved by the giving of certain kinds of food or by forcing certain substances into the dog's mouth. "f It is obvious that reflex exci- tation thus having been accomplished by the edu- cation of the nerve centers to a previously indiffer- ent stimulus the reproduction of the process * Psychische Erregung der Speicheldrusen, J.

NEUROGKAMS 143 through this stimulus is, in principle, an act of physiological memory.* The experiences of the dogs embraced quite large systems of ideas and sensory stimuli which in- cluded the environment of persons and their actions, the furniture, plates, and other objects ; and various ocular, auditory, and other sensory stimuli applied arbitrarily to the dogs. All these experiences had been welded into an associative system and con- served as neurograms. Consequently it was only necessary to stimulate again any element in the neurogram to reproduce the whole process, includ- ing the specific salivary reaction. We shall see later that these experiments acquire additional interest from the fact that in them is to be found the fundamental principle of what under other conditions can be recognized as a psycho- neurosis an abnormal or perverted association and memory. The effects produced by this associa- tion of stimuli may be regarded as the germ of the habit psychosis, and in these experiments we have experimental demonstration of the mechanism of these psychoses but this is another story which we will take up by and by. Recollection This is as good a place as any other to call attention to a certain special form of mem- ory. Recollection and memory are not synonymous * Pawlow overlooked in these experiments the possible, if not probable, intermediary of the emotions in producing the effects. The principle, however, would not be affected thereby. 144 THE UNCONSCIOUS terms. We are accustomed to think of memory as including, in addition to other qualities, recollection, i. e., what is called localization of the experience in time and space. It connotes an awareness of the content of the memory having been once upon a time a previous experience which is more or less accu- rately located in a given past time (yesterday, or a year ago, or twenty years ago), and in certain local relations of space (when we were at school, or rid- ing in a railway car with so and so). But, as Bibot points out, this (relatively to physiological mem- ories) is ... "only a certain kind of memory which we call perfect. ' ' For we have just seen that, when memory is considered as a process, repro- duced physiological processes, which contain no elements of consciousness and therefore of localiza- tion, may be memory. But more than this, I would insist, recollection is only a more perfect kind of conscious memory. Bibot would make recollection a peculiarity of all conscious memory, but this is plainly an oversight. As we saw in previous lec- tures there may be conscious memories which do not contain any element of recollection, or, in other words, such conscious memories resemble in every way, in principle, the reproduction of organic neuron processes in that they have no conscious localization in the past. In dissociated personalities, for in- stance, and in other types of dissociated conditions (functional amnesia, post-hypnotic states, etc.), the names of persons, places, faces, objects, and even complex ideas may flash into the mind without any NEUROGRAMS 145 element of recollection. The person may have no idea whence they come, but by experiment it is easy to demonstrate that they are automatic memories of past experiences.* In the sensory automatisms known as crystal visions, pictures which accurately reproduce, symbolically, past experiences of which the subject has no recollection may vividly arise in the mind. Such pictures are real conscious sym- bolic memories. Dreams, too, as we have seen, may be unrecognized memories in that they may repro- duce conscious experiences, something heard or seen perhaps, but which has been completely for- gotten even when awake. Again, modern methods of investigation show that numerous ideas that oc- cur in the course of our everyday thoughts names, for instance are excerpts from, or vestiges of, pre- vious conscious experiences of which we have no recollection, that is to say, they are memories, re- productions of formerly experienced ideas. In the absence of recollection they seem to belong only to the present. Memories which hold an intermediate place between these automatic memories and those of true recollection are certain memories, like the alphabet or a verse or phrase once learned by heart which we are able at best to localize only dimly in the past. Indeed, the greater part of our vocabu- lary is but conscious memory without localization in * Compare ' ' The Dissociation, ' ' pp. 254, 261. For examples, see also "Multiple Personality," by Boris Sidis, and "The Lowell Case of Amnesia," by Isador Coriat, The Journal of Abnormal Psychol- ogy, Vol. II, p. 93. 146 THE UNCONSCIOUS the past. So we see that recollection is not an es- sential even for conscious memories. It is only a particular phase of memory just as are automatic conscious memories. LECTURE VI SUBCONSCIOUS PROCESSES In what I have said thus far I have had another purpose in view than that of a mere exposition of the psycho-physiological theory of memory. This other and chief purpose has been to lay the founda- tion for a conception of the Unconscious in its larger aspect. We have seen that thoughts and other con- scious experiences that have passed out of mind may be and to an enormous extent are conserved and, from this point of view, may be properly regarded as simply dormant. Further we have seen that all the data collected by experimental pathology and other observations lead to the conclusion that con- servation is effected in the form of neurographic residua or brain neurograms organized physio- logical records of passing mental experiences of all sorts and kinds. We have seen that these neuro- graphic records conserve not only our educational acquisitions and general stock of knowledge all those experiences which we remember but a vast number of others which we cannot spontaneously recall, including, it may be, many which date back to early childhood, and many which we have delib- erately repressed, put out of mind and intentionally 147 148 THE UNCONSCIOUS forgotten. We have also seen that it is not only these mental experiences which occupied the focus of our attention that leave their counterpart in neurograms, but those as well of which we are only partially aware absent-minded thoughts and acts and sensations and perceptions which never entered our awareness at all subconscious or coconscious ideas as they are called. Finally, we have seen that the mental experiences of every state, normal, arti- ficial, or pathological, whatever may be the state of the personal consciousness, are subject to the same principle of conservation. In this way, in the course of any one 's natural life, an enormous field of neuro- grams is formed representing ideas which far tran- scend in multitude and variety those of the personal consciousness at any given moment and all moments, and which are far beyond the voluntary beck and call of the personal consciousness of the individual. Neurograms are concepts and, by the meaning of the concept, they are unconscious. It is not neces- sary to enter into the question whether they are in their ultimate nature psychical or physical. That is a philosophical question.* They are at any rate un- conscious in this sense; they are devoid of con- sciousness, i. e., have none of the psychological at- * I forbear to enter into the question of the nature of conscious- ness and matter. In the last analysis, matter and mind probably are to be identified as different manifestations of one and the same principle the doctrine of monism call it psychical, spiritual, or ma- terial, or energy, as you like, according to your fondness for names. For our purpose it is not necessary to touch this philosophical prob- lem as we are dealing only with specific biological experiences. SUBCONSCIOUS PROCESSES 149 tributes of any of the elements of consciousness, and in the sense in which any physiological ar- rangement or process is not conscious, i. e., is un- conscious. We have here, then, in the concept of brain residual neurograms the fundamental mean- ing of the Unconscious.* The unconscious is the great storehouse of neurograms which are the physiological records of our mental lives. By the terms of the concept neurograms are primarily pas- sive the potential form, as it were, in which psy- chical energy is stored. This is not to say, however, that, from moment to moment, certain ones out of the great mass may not become active processes. On the contrary, according to the theory of memory, when certain complexes of neurograms are stimu- * Also quite commonly termed the Subconscious. Unfortunately the term unconscious, as noun or adjective, is used in two senses, viz., (1) pertaining to unawareness (for example, I am unconscious of such and such a thing), and (2) in the sense of not having the psychological attribute of consciousness, i. e., non-conscious. In the first sense the adjective is used, as in the phrase "uncon- scious process" to define a process of which we are unaware without connotation as to whether it is a psychological process or a brain process; also the noun (The Unconscious) is used to signify some- thing not in awareness regardless of whether that something is psychological or not; on the other hand, as an adjective it is also used, as in the phrase "unconscious ideas," to specifically signify real ideas of which we are unaware. In the second sense, as noun or adjective, it is used to denote specifically brain residua or processes, which, of course, are devoid of consciousness. With this interchange of meaning the term is apt to be confusing and is lacking in precision. In the text un- conscious will be used always with the second meaning, unless in- verted commas or the context plainly indicate the first meaning. (Cf. Lecture VIII, pp. 248-254). 150 THE UNCONSCIOUS lated they take on activity and function the po- tential energy becomes converted into dynamic en- ergy. In correlation with the functioning of such neurographic complexes, the complexes of ideas which they conserve the psychological equivalents are reproduced (according to the doctrines of monism and parallelism) and enter the stream of the personal consciousness. The unconscious be- comes the conscious (monism), or provided with correlated conscious accompaniments (parallelism), and we may speak of the ideas arising out of the un- conscious. ' ' Neurograms may also function as subconscious processes exhibiting intelligence and determining mental and bodily behavior Here two important questions present themselves. Is it a necessary consequence that when unconscious neurograms become active processes psychological equivalents must be awakened; and when they are awakened, must they necessarily enter the stream of the personal consciousness! If both these questions may be answered in the nega- tive, then plainly in either case such active processes become by definition subconscious processes of an unconscious nature in the one case and of a cocon- scious nature in the other. They would be subcon- scious because in the first place they would occur outside of consciousness and there is no awareness of them, and in the second place they would be a dissociated second train of processes distinct from those engaged in the conscious stream of the mo- SUBCONSCIOUS PROCESSES 151 ment. Theoretically such subconscious processes, whether unconscious or coconscious, might perform a variety of functions according to the specificity of their activities. Now, in preceding lectures, when marshalling the evidence for conservation, we met with a large num- ber and variety of phenomena (automatic writing, hallucinations, post-hypnotic phenomena, dreams, ''unconscious" solution of problems, etc.), which clearly demonstrated that memory might be mani- fested by processes of which the individual was un- aware and which were outside the content of con- sciousness. Hence these phenomena presented very clear evidence of the occurrence of processes that may be properly termed subconscious.* Attention, however, was primarily directed to them only so far as they offered evidence of conservation and of the mode by which conservation was effected. But nec- essarily these evidences were subconscious manifes- tations of forgotten experiences (memory), and in so far as this was the case we saw that unconscious neurograms can take on activity and function sub- consciously ; i. e., without their psychological equiva- lents (i. e., correlated conscious memory) entering the stream of the personal consciousness. We may now speak of these processes as subconscious mem- ory. But when their manifestations are carefully scrutinized they will be found to exhibit more than memory. They may, for instance, exhibit logical * Also termed by some writers unconscious. (See preceding foot- note.) 152 THE UNCONSCIOUS elaboration of the original experiences, and what corresponds to fabrication, reasoning, volition and affectivity. Theoretically this is what we should expect if any of the conserved residual experiences of life can function subconsciously. As life's ex- periences include fears, doubts, scruples, wishes, af- fections, resentments, and numerous other affective states, innate dispositions, and instincts, the subcon- scious memory process necessarily may include any of these affective complexes of ideas and tendencies. An affective complex means an idea (or ideas) linked to one or more emotions and feelings. In other words, any acquired residua drawn from the general storehouse of life's experiences may be sys- tematized with feelings and emotions, the innate dispositions and instincts of the organism. Now it is a general psychological law that such affective states tend by the force of their conative impulses to carry the specific ideas with which they are sys- tematized to fulfilment through mental and bodily behavior. Consequently, theoretically, it might thus well be that the residua of diverse experiences, say a fear or a wish, by the force of such impulses might become activated into very specific subcon- scious processes with very specific tendencies ex- pressing themselves in very specific ways, produc- ing very specific and diverse phenomena. Thus memory would be but one of the manifestations of subconscious processes. Now, as a matter of fact, there are a large num- ber of phenomena which not only justify the postu- SUBCONSCIOUS PROCESSES 153 lation of subconscious processes but also the infer- ence that such processes, activated by their affective impulses, may so influence conscious thought that the latter is modified in various ways ; that it may be determined in this or that direction, inhibited, in- terrupted, distorted, made insistent, and given pa- thological traits. There is also a large variety of bodily phenomena which can be explicitly shown to be due to subconscious processes, and many which are only explicable by such a mechanism. Indeed, a subconscious process may become very complex and constellated with any one or many of the psycho- physiological mechanisms of the organism. In spe- cial artificial and pathological conditions where such processes reach their highest development, as manifested through their phenomena, they may ex- hibit that which when consciously performed is un- derstood to be intelligence, comprising reasoning, constructive imagination, volition, and feeling; in short, what is commonly called thought or mental processes. Memory, of course, enters as an intrin- sic element in these manifestations just as it is an intrinsic element in all thought. The automatic script that describes the memories of a long-forgot- ten childhood experience may at the same time rea- son, indulge in jests, rhyme, express cognition and understanding of questions indeed (if put to the test), might not only pass a Binet-Simon examina- tion for intelligence, but take a high rank in a Civil Service examination. In these more elaborate ex- hibitions of subconscious intelligence it is obvious 154 THE UNCONSCIOUS that there is an exuberant efflorescence of the re- sidua deposited in many unconscious fields by life's experiences and synthesized into a subconscious functioning system. It is beyond the scope of this lecture to examine into the particular mechanism by which a subcon- scious process is provoked at all why, for instance, a dormant wish or fear-neurogram becomes acti- vated into a subconscious wish or fear, or having become activated, the mechanism by which such a wish or fear manifests itself in this phenomenon or that or to examine even any large number of the various phenomena which are provoked by subcon- scious processes, and it is not my intention to do so. Such problems belong to special psychology and special pathology. Of recent years, for instance, certain schools of psychology, and in particular the Freudian school, have attempted to establish par- ticular mechanisms by which subconscious processes come into being and express themselves. We are engaged in the preliminary and fundamental task of establishing, if possible, certain basic principles which any mechanism must make use of, and, as a deeper-lying theoretical question, the nature of such processes. The subconscious now belongs to popular speech and it is the fashion of the day to speak of it glibly enough, but I fear it means very little to the aver- age person. It is involved in vagueness if not mys- tery. Yet as a necessary induction from observed facts it has a very precise and concrete meaning SUBCONSCIOUS PROCESSES 155 devoid of abtruseness, just as the other has a pre- cise and concrete meaning. Although subconscious processes were originally postulated on theoretical grounds, the theory is fortunately open to experi- mental tests so that it is capable of being placed on an experimental basis like other concepts of science. It is possible to artificially create such processes and study their phenomena; that is to say, the modes in which they manifest their activities, their influence upon conscious and bodily processes. We can study their effect in inhibiting and distorting thought, in determining it in this or that direction, in creating hallucinatory, emotional, amnesic, and other mental phenomena, in inducing physiological disturbances of motion, sensation, of the viscera, etc. We can also study the capabilities and limita- tions of the subconscious in carrying on intelligent operations below the threshold of consciousness. Again, we can investigate the phenomena of this kind as met with in the course of clinical observa- tions, and by technical methods of research explore the subconscious and thus explicitly reveal the proc- ess underlying and inducing the phenomena. By such methods of investigation the subconscious has been removed from the field of speculative psychol- ogy, and placed in the field of experimental re- search. We have thus been enabled to postulate a subconscious process as a definite concrete process producing very definite phenomena. These proc- esses and their phenomena have become a field of study in themselves and, from my point of view, 156 THE UNCONSCIOUS the determination of the laws of the subconscious should be approached by such experimental and technical methods of research. After its various modes of activity, its capabilities and limitations have been in this way established, its laws can then be applied to the solution of conditions surround- ing particular problems. Though we can determine the actuality of a particular subconscious process this does not mean that we can determine all the components of that process ; we may be able to de- termine many or perhaps none of these: just as among the constituents of a crowd we may discern an active, turbulent group creating a disturbance, though we may not be able to recognize all the com- ponents of the group or the scattered individuals acting in conjunction with it. Nor may we be able to determine the intrinsic nature of a subconscious process whether it is a conscious or unconscious one, but only the actuality of the process, the con- ditions of its activity, and the phenomena which it induces. A subconscious process may be provisionally de- fined as one of which the personality is unaware, which, therefore, is outside the personal conscious- ness, and which is a factor in the determination of conscious and bodily phenomena, or produces ef- fects analogous to those which might be directly or indirectly induced by consciousness. It would be out of the question at this time to enter into an ex- position of the larger subject the multiform phe- nomena of the subconscious, but as its processes are SUBCONSCIOUS PROCESSES 157 fundamental to an understanding of many phenom- ena with which we shall have to deal, we should have a clear understanding of the grounds on which such processes are postulated as specific, concrete occurrences. The classical demonstration of sub- conscious occurrences makes use of certain phenom- ena of hysteria, particularly those of subconscious personalities and artificial "automatic" phenomena like automatic writing. The epoch-making re- searches of Janet * on hysterics and almost coinci- dently with him of Edmund Gurney on hypnotics very clearly established the fact that these phenom- ena are the manifestations of dissociated processes outside of and independent of the personal con- sciousness. Among the phenomena, for example, are motor activities of various kinds such as ordi- narily are or may be induced by conscious intelli- gence. As the individual, owing to anesthesia, may be entirely unaware even that he has performed any such act, the process that performed it must be one that is subconscious. The intrinsic nature of subconscious processes. Janet further brought forward indisputable evidence show- ing that in hysteria these subconscious processes are real coconscious processes. It is only another mode of expressing this to say that there is a dis- sociation or division of consciousness in conse- quence of which certain ideas do not enter the con- * Pierre Janet : L 'automatisme psychologique, Paris, 1889, and numerous other works. 158 THE UNCONSCIOUS tent of the personal consciousness of the individual. It is possible, as he was the first to show, to commu- nicate with and, in hypnotic and other dissociated states, recover memories of these split-off ideas of which the individual is unaware, and thereby estab- lish the principle that these ideas are the subcon- scious process which induces the hysterical phenom- ena. (These phenomena are of a great many kinds and include sensory as well as motor automatisms, inhibition of thought and will, deliria, visceral, emo- tional, and other disturbances of mind and body.) The hysterical subconscious process is thus deter- mined to be a very specific concrete coconscious proc- ess, one, the elements of which are memories and other particular ideas. This type of subconscious process, therefore, may be regarded as the activated residua of antecedent experiences with or without secondary elaboration. All subsequent investiga- tions during the past twenty-five years have served but to confirm the accuracy of Janet's observations and conclusions. It would be out of the question at this time, before coconscious ideas have been sys- tematically studied, to attempt to present the evi- dence on which this interpretation of certain sub- conscious phenomena rests. This will be done in other lectures.* I will simply say that this evi- dence for coconsciousness occurring in certain spe- cial conditions, artificial and pathological, and per- haps as a constituent of the normal content of con- sciousness, is of precisely the same character as * Not included in this volume. SUBCONSCIOUS PROCESSES 159 that for the occurrence of consciousness in any other individual but one 's self. If we reject the evi- dence of hysterical phenomena, of that furnished by a coconscious personality, and by automatic script and speech, etc., we shall have to reject pre- cisely similar evidence for consciousness in other people than ourselves.* The evidence is explicit and not implied. A subconscious personality is a condition where complexes of subconscious processes have been con- stellated into a personal system, manifesting a sec- ondary system of self-consciousness endowed with volition, intelligence, etc. Such a subconscious per- sonality is capable of communicating with the ex- perimenter and describing its own mental processes. It can, after repression of the primary personality, become the sole personality for the time being, and then remember its previous subconscious life, as we all remember our past conscious life, and can give full and explicit information regarding the nature of the subconscious process. By making use of the testimony of a subconscious personality and its va- rious manifestations, we can not only establish the * Cf .

For instance, we can prescribe a conflict between the subconsciousness and the personal conscious- ness, between a subconscious wish and a conscious wish, or volition, and observe the resultant mental and physical behavior, which may be inhibition of thought, hallucinations, amnesia, motor phenomena, etc. The possibilities and limitations of subcon- scious influences can in this way be experimentally studied. Subconscious personalities, therefore, afford a valuable means for studying the mechanism of the mind.* The conclusion, then, seems compulsory that the subconscious processes in many conditions, particu- larly those that are artificially induced and those that are pathological, are coconscious processes. There are other phenomena, however, which re- quire the postulation of a subconscious process, yet which, when the subconscious is searched by the * The value of subconscious personalities for this purpose has been overlooked, owing, I suppose, to such conditions being unusual and bizarre, and the assumption that they have little in common with ordinary subconscious processes. But it ought to be obvious that in principle it makes little difference whether a subconscious system is constellated into a large self-conscious system called a personality, or whether it is restricted to a system limited to a few particular coconscious ideas. In the former case the possibilities of its inter- fering with the personal consciousness may be more extended and more influential, that is all. SUBCONSCIOUS PROCESSES 161 same methods made use of in hysterical phenomena, do not reveal explicit evidence of coconsciousness. An analysis of the subconscious revelations as well as the phenomena themselves seems to favor the interpretation that in some cases the underlying process is in part and in others wholly unconscious. The only ground for the interpretation that all sub- conscious processes are wholly conscious is the assumption that, as some are conscious, all must be. This is as unsound as the assumption .that, because at the other end of the scale some complex actions (e. g., those performed by decerebrated animals) are intelligent and yet performed by processes necessarily unconscious, therefore all actions not under the guidance of the personal consciousness are performed by unconscious processes. If some subconscious processes are unconscious they are equivalent to physiological processes such as, ex hypothesi, are correlated with all conscious processes and perhaps may be identified with them. In truth, they mean nothing more nor less than "un- conscious cerebration." We can say at once that considering the complex- ity and multiformity of psycho-physiological phe- nomena there would seem to be no a priori reason why all subconscious phenomena must be the same in respect to being either coconscious or unconscious ; some may be the one and some the other. It is plainly a matter of interpretation of the facts and there still exists some difference of opinion. The problem is a very difficult one to settle by methods 162 THE UNCONSCIOUS at present available; yet it can only be settled by the same methods, in principle, that we depend upon to determine the reality of a personal consciousness in other persons than ourselves. No amount of a priori argument will suffice. Perhaps some day a criterion of a conscious state of which the individual is unaware will be found, just as the psycho-galvanic phenomenon is possibly a criterion of an effective state. Any conclusions which we reach at present should be regarded as provisional.* SPECIAL PROBLEMS OF THE SUBCONSCIOUS As one of our foremost psychologists has said, the subconscious is not only the most important problem of psychology, it is the problem. But of * Of course, from a practical (clinical) point of view, it is of no consequence whether given phenomena are induced by coconscious or unconscious processes; the individual is not aware of either. Let me answer, however, a strange objection that has been made to such an inquiry. It has been objected that as it makes no practical difference whether the subconscious process, which induces a given phenomenon, is coconscious or unconscious, and as in many given cases it is difficult or impossible to determine the question, therefore, that such inquiries are useless. Plainly such an objection only concerns applied science, not science itself. It concerns only the practicing physician who deals solely with reactions. Likewise it makes no difference to the practicing chemist whether some atoms are positive and some negative ions, and whether on further analysis they are systems of electrons, and whether, again, electrons are points of electricity. The practical chemist deals only with reactions. Such questions, however, having to do with the ultimate nature of matter are of the highest interest to science. Likewise the nature of sub- conscious processes is of the highest interest to psychological science. SUBCONSCIOUS PROCESSES 163 course it involves many problems of practical and theoretical interest. Among them are : First of all the evidential justification of the postulation of subconscious processes in general. Second; the intrinsic nature of such processes. In other words and more specifically, whether the neurograms of experiences after becoming active subconscious processes continue to be devoid of con- sciousness, nothing but a brain process, i. e., un- conscious; or whether in becoming activated they become conscious (monism), or acquire conscious equivalents (parallelism), notwithstanding they are outside (dissociated from) the content of the per- sonal consciousness. Third; the kind and complexity of functions a subconscious process can perform. Can it perform the same functions as are ordinarily performed by conscious intelligence (as we commonly understand that term) ; that is to say memory, perception, rea- soning, imagination, volition, affectivity, etc.? If so, to what extent? Fourth; are the processes of the conscious mind only a part of a larger mechanism of which a sub- merged part is a subconscious process? Fifth; to what extent can and do subconscious processes determine the processes of the conscious mind and bodily behavior in normal and abnormal conditions ? These are some of the problems of the subcon- scious which for the most part have been only in- completely investigated. 164 THE UNCONSCIOUS It is, of course, beyond the scope of these intro- ductory lectures to discuss with any completeness the evidence at hand bearing upon these problems or to even touch upon many of the points involved. We may, however, study more deeply than we have done some of the phenomena with which we have become familiar with a view to seeing what light they throw upon some of these problems, particu- larly the first three. 1, 2, and 3; Actuality, Intrinsic Nature and Intelligence of Subconscious Processes. As to the first question, whether subconscious processes can be established in principle as a sound induction from experimental and clinical facts and not merely as a hypothetical concept, I have already pointed out that many mani- festations of conservation already cited in the ex- position of the theory of memory are of equal evi- dential value for the actuality of such processes. Let us now consider them in more detail from the point of view, more particularly, of the second and third questions the intrinsic nature (whether co- conscious or unconscious) and intelligence of the underlying processes at work. In any given case however the actuality of the subconscious process must always be first demonstrated. If we leave aside those conditions (hysteria, cocon- scious personalities) wherein specific memory of a coconscious process can be recovered, or such a process can be directly communicated with (auto- matic writing and speech), the conditions required SUBCONSCIOUS PROCESSES 165 for the valid postulation of a subconscious process underlying any given phenomenon are: first, that the causal factor shall be positively known; second, that it shall be an antecedent experience ; and, third, that it shall not be in the content of consciousness at the moment of the occurrence of the phenomenon. If the causal factor and the phenomenon are both known, then the only unknown factor to be deter- mined is the process, if any, intervening between the two. If this is not in consciousness, a subcon- scious process must be postulated. Obviously, if the known causal factor is immedi- ately related to the caused phenomenon, the sub- conscious process must be the causal factor itself. But if the known causal factor is not immediately related to the caused phenomenon, there must be an intervening process which must be subconscious, perhaps consisting of a succession of processes eventuating in the final phenomenon. For instance, if the causal factor is a hypnotic suggestion (for which there is afterwards amnesia) that the sub- ject when awake shall automatically raise the right arm, a subconscious process which is the memory of that suggestion immediately provokes the automatic phenomenon. If, however, the suggestion is that of a series of automatic actions involving compli- cated behavior, or if it is a mathematical calculation, the intervening process which provokes the end re- sult must not only be subconscious but must be a more or less complicated succession of processes. When, on the other hand, the causal factor is not 166 THE UNCONSCIOUS known but only inferred with greater or less prob- ability, the justification of the postulation of a sub- conscious process may be invalidated by the uncer- tainty of the inference. If for example a person raises his right hand or has a number come into his head without obvious cause, any inferred ante- cedent experience as the causal factor must be open to more or less doubt, and, therefore, a subconscious process cannot be postulated with certainty. This uncertainty seriously affects the validity of con- clusions drawn from clinical phenomena where the antecedent experience as well as a subconscious proc- ess must be inferred and perhaps even a matter of guesswork. Let us examine then, a few selected phenomena where the causal factor in the process is a known antecedent conscious experience, one which can be logically related to the succeeding phenomenon only by the postulation of an intervening process of some kind. By an analysis of the antecedent ex- perience and the caused phenomenon into their con- stituent elements we shall often be able to infer the functional characteristics of this intervening process. Then, if the subject is a favorable one, by the use of hypnotic and other methods we may be able to obtain an insight into the intrinsic nature of the subconscious process and determine how far it is conscious and how far unconscious. Neces- sarily the most available phenomena are those ex- perimentally induced. We can arrange beforehand the causal experience and the phenomenon which it SUBCONSCIOUS PROCESSES 167 is to determine an hallucination, a motor automa- tism, a dream, a conscious process of thought, or the product of an intellectual operation. The num- ber of observations we shall examine might be made much larger and the types more varied. Those I have selected have such close analogies with certain expe- riences of everyday and pathological life that what is found to be true of them will afford valuable funda- mentals in the elucidation of these latter experiences.* Subconscious processes in which the causal factor was antecedently known I. The evidential value of post- hypnotic phenomena ranks perhaps in the first place for our purpose as the conditions under which they occur are largely under control. Among these showing subconscious processes of a high order of intelligence are : (a) The well-known subconscious mathematical calculations which I cited in a previous lecture (p. 96). There is no possible explanation of this phenomenon except that the calculation was a sub- conscious process and done either coconsciously or unconsciously. That it may be done, in some cases, by coconscious processes of which the subject is unaware is substantiated by the evidence.! In * I have passed over the classical hysterical phenomena as they open a very large subject which needs a special treatment by itself. The subconscious processes underlying them, so far as they have been determined, are, as I have explained, admittedly coconscious, though some may be in part unconscious. They are too complicated to be entered into here. t Prince: Experiments to Determine Coconscious (Subconscious) Ideation, Journal of Abnormal Psychology, April-May, 1908, 168 THE UNCONSCIOUS other cases this does not appear to be wholly the case if we can rely upon hypnotic memories. We will examine this process in connection with: (b) A second class of post-hypnotic phenomena, namely, those of suggested actions carried out by the subject more or less automatically, in a sort of absent-minded way, without his being aware of what he is doing. The subject is directed in hyp- nosis to perform such or such an action after being awakened. Sometimes the suggested action is per- formed consciously, the suggested ideas with their impulses arising in his mind, but without his know- ing why. In other instances, however, he performs the action automatically without being consciously aware at the moment that he is doing it, his atten- tion being directed toward something else. Such actions must be performed by some kind of subcon- scious processes instigated by the ideas suggested in hypnosis. Now hypnotic and other technically evoked mem- ories sometimes reveal the conscious content of the processes involved in both classes of phenomena. For instance: two intelligent subjects, who have been the object of extensive observations on this point, are able to recall in hypnosis the previous occurrence of coconscious ideas of a peculiar char- acter. The description of these ideas has been veiy precise and has carried a conviction, I believe, to all those who have had an opportunity to be present at these observations that these recollections were SUBCONSCIOUS PROCESSES 169 true memories and not fabrications.* The state- ments of these subjects is that in their own cases, under certain conditions of everyday life, cocon- scious ideas of which the principal consciousness is not aware emerge into the subconscious, persist for a longer or shorter time, and then subside to be re- placed by others. So long as the conditions of their occurrence continue these coconscious ideas keep coming and going, interchanging with one another. Sometimes these ideas take the form of images, or what is described as visual " pictures." When the conditions are those of the subconscious solution of a mathematical calculation then the same ' ' pictures ' ' occur and take the form of the figures involved in the calculation ; the figures come and go, apparently add, subtract, and multiply themselves until the final result appears in figures. An example will make this clear. While the subject was in hypnosis the problem was given to add 458 and 367, the calculation to be * Among these I might mention the names of a dozen or more well-known psychologists and physicians of experience and repute who have observed one or both of these cases. Through the kindness of Dr. G. A. Waterman I have had an opportunity to investigate a third case, one of his patients, who described similar coconscious "pictures" accompanying certain impulsive conscious acts. The pic- tures, when of persons, were described as ' ' life size, ' ' and were likened to those of a cinematograph. Also, as with one of my cases, suggested post-hypnotic actions were accompanied by such cocon- scious pictures representing in successive stages the act to be per- formed. An analysis of both the impulsive and the suggested phe- nomena seemed to clearly show that the pictures emerged from a deeper lying submerged process induced by the residuum of a dream and of the suggestion, respectively. 170 THE UNCONSCIOUS done subconsciously after she was awake. The problem was successfully accomplished in the usual way. The mode in which the calculation was effected was then investigated with the following result : In what may be termed for convenience the secondary consciousness, i. e., the subconsciousness, the numbers 458 and 367 appeared as distinct visu- alizations. These numbers were placed one over the other, "with a line underneath them such as one makes in adding. The visualization kept com- ing and going; sometimes the line was crooked and sometimes it was straight. The secondary con- sciousness did not do the sum at once, but by piece- meal. It took a long time before it was completed. ' ' The sum was not apparently done as soon as one would do it when awake, by volitional calculation, "but rather the figures added themselves, in a curi- ous sort of way. The numbers were visualized and the visualization kept coming and going and the columns at different times added themselves, as it seemed, the result appearing at the bottom." In another problem (453 to be multiplied by 6) the process \vas described as follows: The numbers were visualized in a line, thus, 453 x 6. Then the 6 arranged itself under the 453. The numbers kept coming and going the same as before. Sometimes, however, they added themselves, and sometimes the 6 subtracted itself from the larger number. Finally, however, the result was obtained. As in the first problem, the numbers kept coming and going in the secondary consciousness until the problem was SUBCONSCIOUS PROCESSES 171 solved and then they ceased to appear. It is to be understood, of course, that the principal or per- sonal consciousness was not aware of these cocon- scious figures, or even that any calculation was being or to be performed. In suggested post-hypnotic actions, the pictures that come and go correspond to and represent the details of the action as it is carried out. Each detail is preceded or accompanied by its coconscious image or picture. Likewise, when somatic phe- nomena have followed dreams, pictures represent- ing certain elements of the dream have appeared as secondary conscious states. When the subject has been disturbed by some unsolved moral or social problem (not suggested) the pictures have been symbolic representations of the disturbing doubts and scruples.* One of these two subjects, while in hypnosis and able to recollect what goes on in the secondary con- sciousness, thus describes the coconscious process during the spontaneous subconscious solution of problems. ''When a problem on which my waking self is engaged remains unsettled, it is still kept in mind by the secondary consciousness even thougli put aside by my waking self. My secondary con- sciousness often helps me to solve problems which my waking consciousness has found difficulty in doing. But it is not my secondary consciousness * Cf. Lecture IV. These coconscious pictures are so varied and occur in so many relations that they need to be studied by them- selves. 172 THE UNCONSCIOUS that accomplishes the final solution itself, but it helps in the following way: Suppose, for instance, I am trying to translate a difficult passage in Vir- gil. I work at it for some time and am puzzled. Finally, unable to do it, I put it aside, leaving it unsolved. I decide that it is not worth bothering about and so put it out -of my mind. But it is a mistake to say you put it out of your mind. What you do is, you put it into your mind ; that is to say, you don't put it out of your mind if the problem remains unsolved and unsettled. By putting it into your mind I mean that, although the waking con- sciousness may have put it aside, the problem still remains in the secondary consciousness. In the example I used the memory of the passage from Virgil would be retained persistently by my secon- dary consciousness. Then from time to time a whole lot of fragmentary memories and thoughts connected with the passage would arise in this con- sciousness. Some of these thoughts, perhaps, would be memories of the rules of grammar, or different meanings of words in the passage, in fact, anything I had read, or thought, or experienced in connection with the problem. These would not be logical, con- nected thoughts, and they would not solve the prob- lem. My secondary consciousness does not actually do this, i. e., in the example taken, translate the passage. The translation is not effected here. But later when my waking consciousness thinks of the problem again, these fragmentary thoughts of my SUBCONSCIOUS PROCESSES 173 secondary consciousness arise in my mind, and with this information I complete the translation. The actual translation is put together by my waking consciousness.* I am not conscious of the fact that these fragments of knowledge existed previously in my secondary consciousness. I do not remember a problem ever to have been solved by the secondary consciousness.! It is always solved by the waking self, although the material for solving it may come from the secondary. When my waking conscious- ness solves it in this way, the solution seems to come in a miraculous sort of way, sometimes as if it came to me from somewhere else than my own * This, of course, so far as she could determine from the data of memory. The more correct interpretation probably is that the thoughts of the ' ' secondary consciousness ' ' were supplied by a still deeper underlying subconscious process, certain elements of which emerged as dissociated conscious states (not in the focus of atten- tion). This same process probably was the real agent in doing the actual translation, and later thrust the necessary data into awareness in such fashion that the translation seemed to be performed con- sciously. If all the required data is supplied to consciousness the problem is thereby done. t The subject here, of course, refers not to experimental but to spontaneous solutions. When experimentally performed the whole problem was solved subconsciously. Furthermore, a memory of a de- tail of this kind of remote experiences obviously would not be re- liable, but only immediately after an experience. In fact, sponta- neous solutions sometimes occurred entirely subconsciously. (Cf. Lecture VII.) In the experimental calculation experiments the solution is made subconsciously in accordance with the prescribed conditions of the experiment. In other observations on this sub- ject the coconscious pictures represented past experiences of the subject, much as do crystal visions, and suggest that these past experiences were functioning unconsciously. 174 THE UNCONSCIOUS mind. I have sometimes thought, in consequence, that I had solved it in my sleep. ' ' * A series of observations conducted with a fourth subject (0. N.) gave the following results, briefly summarized. (This subject, like the others, is prac- ticed in introspection and can differentiate her memories with precision.) She distinguishes "two strata" in her mental processes (an upper and lower). The "upper stratum" consists of the thoughts in the focus of attention. The lower (also called the background of her mind) consists of the perceptions and thoughts which are not in the focus. This stratum, of course, corresponds with what is commonly recognized as the fringe of conscious- ness, and, as is usual, when her attention is directed elsewhere she is not aware of it. She can, however, bring this fringe within the field of attention and then she becomes aware of, or rather remembers, its content during the preceding moment. To be able to do this is nothing out of the ordinary, but what is unusual is this: by a trick of abstraction which she has long practiced, she can bring the memory of the fringe or stratum into the full light of awareness and then it is discovered that it has been exceedingly rich in thoughts, far richer than ordinary attention would show and a fringe is sup- posed to be. It is indeed a veritable coconscious- ness in which there goes on a secondary stream of thoughts often of an entirely different character * Prince : Some of the Present Problems of Abnormal Psychol- ogy, Congress of Arts and Sciences, St. Louis, 1904, V; 5, p. 770. SUBCONSCIOUS PROCESSES 175 and with different affects from those of the upper stratum. It is common for thoughts which she has resolutely put out of her mind as intolerable or un- acceptable, or problems which have not been solved, to continue functioning in the lower stratum with- out entering awareness.* She can, however, at any time become aware of them by the trick of abstrac- tion referred to, and sometimes they emerge appar- ently spontaneously and suddenly! replace the "upper stratum." In hypnosis also the content of the lower stratum can be distinctly recalled. Now the point I have been coming to is, the sub- ject has acquired the habit of postponing the deci- sion of many everyday problems and giving them, as a matter of convenience, to this second stratum or fringe to solve. She puts one aside, that is out of (or into) her mind and it goes into this stratum. Then, later, when the time for action comes, she * Practically similar conditions I have found in B. C. A., and Miss B., though described by the subjects in different phraseology. t For instance, to take a sensational example, on one occasion in the midst of hilarity while singing, laughing, etc., she suddenly be- came depressed and burst into tears. What happened was this: It was a sorrowful anniversary, and in the ' ' lower stratum ' ' sad mem- ories had been recurring during the period of hilarity. These mem- ories had come into consciousness early in the morning, but she had resolutely put them out of her mind. They had, however, kept re- curring in the lower stratum, and suddenly emerged into the upper stratum of consciousness with the startling effect described. More commonly, however, the emergence of the lower stratum is simply a shifting play of thought. It is interesting to note that censored thoughts and temptations are apt to go into the lower stratum and here with their affects continue at play. These sometimes reappear as dreams. 176 THE UNCONSCIOUS voluntarily goes into abstraction, becomes aware of the subconscious thoughts of the second stratum and, lo and behold! the problem is found to be solved. If a plan of action, all the details are found arranged as if planned "consciously." If asked a moment before what plans had been decided upon and decision reached she would have been obliged in her conscious ignorance to reply, "I don't know." * An analysis of these different observations shows, * The validity of the evidence of memory as applied to sub- conscious processes needs to be carefully weighed. It is a question of method, and if the method is fallacious all conclusions fall to the ground. In the sciences of normal psychology and psychiatry and psychopathology, the data given by memory are and necessarily must be relied upon to furnish a knowledge of the content of mental proc- esses and the mental symptoms, and all methods of psychological analysis are based on the data of memory. Without such data there could be no such sciences. As a matter of experience the method is found to be reliable when properly checked by multiple observations. If by special methods of technique mental processes, which do not enter the awareness of the moment, are later brought into conscious- ness as data of memory, are these data per contra to be rejected as hallucinatory? This is what their rejection would mean. Now, as a fact, there are phenomena, like coconscious personalities, which compel the postulation of coconscious processes. If this is the case, if there are coconscious processes which do not enter awareness, it would be tne strangest thing if there were not conditions of the personality in which a memory of these processes could be ob- tained. This fact would have to be explained. The bringing of co- conscious processes into consciousness as data of memory does not seem therefore to be anything a priori improbable and there would seem to be no reason why the memory of them should be more un- reliable than that of conscious processes in the forms of attention. Indeed, if the fringe of consciousness be regarded as coconscious, it is an every-day act common to everybody. Such data necessarily should be checked up by multiple observations. SUBCONSCIOUS PROCESSES 177 first, that the post-hypnotic phenomena calcula- tions (a) and actions (b) were performed by a subconscious process. Of this there can be no man- ner of doubt, even if the subsequent hypnotic mem- ories of the process be rejected as untrustworthy. The phenomenon the answer to the mathematical problem in the one case and the motor acts in the other is so logically related to the suggestion, and can be predicted with such certainty, that only a causal relation can be admitted. Second, in the calculation phenomena the process is clearly of an intellectual character requiring reasoning and the cooperation of mathematical memory. (Reasoning is more conspicuous when the problem is more complicated, as in the calculation of the number of seconds intervening between, say, twenty-two minutes past eleven and seventeen min- utes past three o'clock.)* The phenomenon is the solution of a problem. The final phenomenon was not immediately re- lated to the suggested idea. It was the final result of a quite long series of logical processes of a more or less complex character occurring over a period of time as in conscious calculation. Conation (voli- tion?) would seem also to be essential to carry the suggested idea to fulfilment. Subconscious cogni- tion would seem also to be required. There must have been an intelligent appreciation of what the * For examples of this kind, see Prince, Experiments to Determine Coconscious Ideation, Journal of Abnormal Psychology, April-May, 1908. 178 THE UNCONSCIOUS problem was and as soon as the solution was accom- plished the process stopped. Eandom figuring did not continue. In the post-hypnotic motor acts conation is obvi- ous. Here too there is a series of subconscious proc- esses covering a period of time and carrying out a purpose. The suggested causal idea did not include the acts necessary for the fulfillment of the idea. Each step was adapted to an end, ceased as soon as it accomplished that end, and was followed by an- other in logical sequence, the whole taking place as if performed by an intelligence. Eeasoning may or may not be involved according to the complexity of the actions. Third; the coconscious figures in the calculation experiments do not constitute the whole of the proc- ess. They would seem to be the product of some deeper underlying process. The figures "kept com- ing and going" and seemed to "add themselves." There was no conscious process that related the figures to one another and determined whether the problem was one of addition or multiplication as is the case when we do a calculation consciously; that is to say, of course, if the hypnotic personality remembered the whole of the conscious calculation. It was more as if there was an underlying uncon- scious process which did the calculation, certain final results of which appeared as dissociated states of consciousness, i. e., figures which did not enter the personal consciousness. The process reminds us of the printing of visible letters by the concealed SUBCONSCIOUS PROCESSES 179 works of a typewriter; or of visible letters of an electrically illuminated sign appearing and disap- pearing according as the concealed mechanism is worked. This interpretation is in entire accord with the spontaneous occurrence of the coconscious images during the everyday life of these subjects. These images were pictorial representations of an- tecedent thoughts and seemed to be the products or elements of these thoughts apparently function- ing as underlying unconscious processes. Likewise, in post-hypnotic suggested actions, I have not been able to obtain memories of coconscious thoughts directing the actions, but only the images described. These behave as if they were the product of another underlying process determining the action. Infer- ences of this sort are as compulsory as the inference that the illumination of a sensitive plate observed in the study of radio-activity must be due to the bom- bardment of the plate by invisible particles emitted by the radio-active substance. These particles and the process which ejects them can only be inferred from the effects which they produce. So, in the above observations, it would seem as if the cocon- scious figures, and other images involved, must be ejected as conscious phenomena by an underlying process. There is no explicit evidence that this is conscious. I said advisedly, a moment ago, "if the hypnotic personality remembered the whole of the conscious calculation, ' ' for, as a matter of fact, we find, when we examine several different hypnotic states in the 180 THE UNCONSCIOUS same subject, that their memories for coconscious ideas are not coextensive, one (or more) being fuller than another. Indeed in certain states there may not be any such memories at all. It is necessary, therefore, to obtain by hypnosis a degree of disso- ciation which will allow the complete memories of this kind to be evoked. In the subjects I made use of this procedure was followed. Theoretically it might be held that, no matter how complete the mem- ories evoked in the various states, some other state might possibly be obtained in which still more com- plete memory would be manifested. Theoretically this is true and all conclusions are subject to this criticism. Practically, however, I found, when mak- ing these investigations, that I seemed to have come to the limit of such possibilities, for, obtain as I would new dissociated arrangements of personality, after a certain point no additional memories could be evoked. There is still another possibility that there may be coconscious processes for which no memories can be evoked by any method or in any state. II. Artificially induced visual hallucinations with which we have already become familiar can, as we have seen, only be interpreted as the product of subconscious processes. If only because of the im- portant part that hallucinations play in insanity and other pathological states and of the frequency with which they occur in normal people (mystics and others), the characteristics of the subconscious process are well worth closer study. What is found SUBCONSCIOUS PROCESSES 181 to be true of the experimental type is probably true of the spontaneous variety whether occurring in pathological or normal conditions. Indeed, as we shall see, spontaneous hallucinations have the same characteristics. We have considered them thus far only from two points of view, viz. (1) as evidence of conservation of forgotten experiences, and (2) as evidence for specific residua of such experiences functioning as subconscious processes. Now, arti- ficial visual hallucinations, like the spontaneous ones, may be limited relatively speaking to what is apparently little more than an exact reproduc- tion of an antecedent visual perception, e. g., a person or object. But, generally speaking, it is more than this and when analyzed will be found almost always to be the expression of a complicated process. For instance, take the relatively simple crystal vision, of the subject smoking a cigarette in a particular situation during hypnosis, which I have previously cited. (Lecture III.) As a matter of fact, the subject had no primary visual percep- tions at the time of the original episode at all. She was in hypnosis, her eyes were closed, and she did not and could not see herself (particularly her own face) or the cigarette or her surroundings. And yet the vision pictured everything exactly as it had occurred in my presence, even to the expression of her features. Looking into the crystal the subject saw herself sitting in a particular place, enacting a series of movements, talking and smoking a cigar- ette with a peculiar smile and expression of enjoy- 182 THE UNCONSCIOUS ment on her face.* For this experience there was complete amnesia after waking from hypnosis and at the time of the vision. Now consider further the facts and their impli- cations. In the mechanism of the process eventuat- ing in the visual phenomenon we obviously have two known factors: the antecedent causal factor the hypnotic episode and, after a time interval, the end result the vision. As there was no conscious memory of the hypnotic episode the neurograms of the latter must have functioned subconsciously to have produced the vision. But what particular neurograms? As the subject's eyes had been closed in hypnosis, and, in any event, as she could not have seen her own face, there were at the time no visual perceptions of herself smoking a cigarette, and therefore the vision could not have been simply a re- production of a visual experience. There were, how- ever, tactual, gustatory, and other perceptions and ideas of self and environment, and these perceptions and ideas of course possessed secondary visual im- ages.-^ The simplest mechanism would be that the neurograms of this complex of perception and ideas of self, etc., functioned subconsciously and their secondary visual images emerged into consciousness to be the vision. I give this as the simplest mechan- ism by which we can conceive of a visual representa- * The Dissociation, pp. 55, 56. f It is only necessary to close one 's eyes, then grimace and move one's limbs to become conscious of these secondary images which picture each movement of the features, etc. SUBCONSCIOUS PROCESSES 183 tion of an antecedent experience emerging out of a subconscious process.* There is a considerable body of data supporting this interpretation. But the original experiences of the episode in- cluded more than the mere perceptions and move- ments of the subject. They included trains of thought and enjoyment of the cigarette smoking experience. All formed a complex of which the tactual and other perceptions of self were subordi- nate elements. At one moment, of course, one ele- ment, and, at another moment another element, had been in the focus of awareness, the others becoming shifted into the fringe where at all times were sec- ondary visual images of herself. Did the subcon- scious process underlying the vision include the whole of this complex? As to this, one peculiarity of the vision has much significance. In behavior it acted after the manner of a cinematographic or "moving picture," and delineated each successive movement of the episode, as if a rapid series of photographs had been taken for reproduction. In * The mechanism is probably not quite so simple as this, proba- bly past visual perceptions of self and the environment took part, so that the vision was a fusion or composite of these older primary images and the secondary images. The principle of mechanism, how- ever, would not be affected by this added element. Sidis (The Doc- trine of Primary and Secondary Sensory Elements, Psych. Bev., January-March, 1908) has maintained that all hallucinations are the emerging of the secondary images of previous perceptions. If, on the other hand, the vision be interpreted as something fabricated by the subconscious process as must be the case with some hallucina- tions then this process must have been much more complicated than memory. Something akin at least to constructive imagination and intelligence that translated the experiences into visual terms. 184 THE UNCONSCIOUS this manner even the emotional and changing play of the features of the vision-self, expressive of the previous thoughts and enjoyment, were depicted. Such a cinematographic series of visual images would seem to require a concurrent subconscious process to produce the successive changes in the hallucinatory images. As these changes apparently correspond from moment to moment with the changes that had occurred in the content of con- sciousness during the causal episode, it would also seem that the subconscious process was a reproduc- tion in subconscious terms of substantially the whole original mental episode. This conclusion is forti- fied by the following additional facts : In many experiments of this kind, if the subject's face be watched during the visualization, it will be observed that it shows the same play of features as is dis- played by the vision face,* and the visualizer at the same moment experiences the same emotion as is expressed by the features of the vision facefi and sometimes knows "what her [my] vision self is thinking about." In other words, in particular in- stances, sometimes the feelings alone and sometimes both the thoughts and feelings expressed in panto- mime in the hallucination arise at the same moment in consciousness. This would seem to indicate that the same processes which determined the mimetic play of features in the hallucination were deter- mining at the same moment the same play in the * That is to say, as described by the visualizer. t Cf, The Dissociation, pp. 211-220, SUBCONSCIOUS PROCESSES 185 features of the visualizer, and that these processes were a subconscious memory of substantially all the original perceptions and thoughts. That is to say, this memory in such cases remains sometimes en- tirely subconscious and sometimes emerges into con- sciousness. The hallucination is simply a projected visualization induced by what is taking place sub- consciously in the subject's mind at the moment. Whether this shall remain entirely subconscious or shall emerge partially or wholly into consciousness depends upon psychological conditions peculiar to the subject. That even when the thoughts of the causal experi- ence emerge in consciousness along with the vision a portion of the functioning complex e. g., the per- ceptual elements may still remain submerged is shown by the following example : The vision, one of several of the same kind, portrayed in pantomime an elaborate nocturnal somnambulistic act. It rep- resented the subject walking in her sleep with eyes closed ; then sitting before the fire in profound and depressing thought; then joyously dancing; then writing letters, etc., and finally ascending the stairs, unconsciously dropping one of the letters from her hand on the way* and returning to bed. During the visualization the thoughts and feelings of the vision-self, even the contents of the letters, arose in * At this point the subject watching the vision remarked, ' ' I drop one of the letters, but I do not know I have done so. ' ' In other words, conscious of the content of the somnambulist's consciousness, the visualizer knows that there is no awareness of this act. The letter was afterward found by the servant on the stairs. 186 THE UNCONSCIOUS the mind of the visualizer whose features and tone of voice betrayed the feelings. The point to be noted in this observation is that the vision reproduced as a detail of the somnambu- listic act the accidental dropping of a letter from the*~hand of the somnambulist who was unaware of the fact; it reproduced what was not in conscious experience. How came it that an act for which there had been no awareness could appear in the vision? The only explanation is that originally in the somnambulistic state, a is so commonly ob- served in hypnotic somnambulism, there was a sub- conscious tactual perception (with secondary visual images?) of dropping the letter and now the mem- ory of this antecedent perception, functioning sub- consciously, induced this detail of the vision. The general conclusion then would seem to be justified that this hallucination was determined by a fairly large complex of antecedent somnambulistic experi- ences of which a part emerged as the hallucination and the thoughts of the somnambulist into con- sciousness, and a part the tactual and other per- ceptions remained submerged as the subconscious process. How much more may have been contained in this process the facts do not enable us to deter- mine. An examination, then, of even the more simple artificial hallucinations discloses that underlying them there is a residual process which is quite an extensive subconscious memory of antecedent thoughts, perceptions and affective experiences. SUBCONSCIOUS PROCESSES 187 Whether this memory is only an unconscious func- tioning neurogram or whether it is also a cocon- scious memory, or partly both, cannot be determined from the data.* The bearing of these results upon the interpretation of insane hallucinations is obvi- ous. Our examination of subconscious processes in the two classes of phenomena thus far studied post hypnotic phenomena and artificial hallucinations- permits the following general conclusions: First, there is positive evidence to show that in some in- stances, in their intrinsic nature, they are cocon- scious. In other instances, in the absence of such evi- dence, it is permissible to regard them as uncon- scious. Second, that in the quality of the functions performed they frequently exhibit that which is characteristic of Intelligence. This characteristic will be seen to be still more pronounced in the phe- nomena which we shall next study. * Coconscious ideas may provoke hallucinations. (For examples consult "Hallucinations" in Index to The Dissociation.) LECTURE VII SUBCONSCIOUS INTELLIGENCE (Continued) III. Subconscious intelligence underlying spon- taneous hallucinations. Spontaneous hallucinations often offer opportunities to study subconscious proc- esses exhibiting constructive intelligence. Although properly belonging to clinical phenomena, they often can be so clearly related to an antecedent experience as to allow us to determine the causal factor with the same exactness as in the experimental type, and, therefore, to infer the connecting subconscious link with equal probability. Some of these spontaneous visions indicate that the subconscious link must be of considerable complexity and equivalent to logical processes of reasoning, volition, and pur- posive intelligence. Sometimes the same subcon- scious processes which fabricate the vision deter- mine also other processes of conscious thought and movements. In illustration I may cite an incident in the life of Miss B., which I have previously described : "Miss B., as a child, frequently had visions of the Madonna and Christ, and used to believe that she had actually seen them. It was her custom when in trouble, if it was only a matter of her school lessons, or something that she had lost, to resort to prayer. Then she would be apt to have a vision of Christ. The vision 188 SUBCONSCIOUS INTELLIGENCE 189 never spoke, but sometimes made signs to her, mid the expression of His face made her feel that all was well. After the vision passed she felt that her difficulties were removed, and if it was a bothersome lesson which she had been unable to understand it all became intelligible at once. Or, if it was something that she had lost, she at once went to the spot where it was." . . . [For example, while under observation.] "Miss B. had lost a bank check and was much troubled concerning it. For five days she had made an unsuccessful hunt for it, systematically going through everything in her room. She remembered distinctly placing the check between the leaves of a book, when some one knocked at her door, and this was the last she saw of the check. She had be- come very much troubled about the matter, and in consequence, after going to bed that night she was unable to sleep, and rose sev- eral times to make a further hunt. Finally, at 3 o'clock in the morn- ing, she went to bed and fell asleep. At 4 o'clock she woke with the consciousness of a presence in the room. She arose, and in a moment saw a vision of Christ, who did not speak, but smiled. She at once felt, as she used to, that everything was well, and that the vision foretold that she should find the check. All her anxiety left her at once. The figure retreated toward the bureau, but the thought flashed into her mind that the lost check was in the drawer of her desk. A search, however, showed that it was not there. She then walked automatically to the bureau, opened the top drawer, took out some stuff upon which she had been sewing, unfolded it, and there was the check along with one or two other papers. "Neither Miss B. nor BII [hypnosis] has any memory of any specific thought which directed her to open the drawer and take out her sewing, nor of any conscious idea that the check was there. Rather, she did it, so far as her consciousness goes, auto- matically, as she used to do automatic writing."* Further investigation revealed the fact that the money had been put away absent-mindedly and ' ' un- * The Dissociation, Appendix L, p. 548. 190 THE UNCONSCIOUS consciously"; in hypnosis the memory of this act was recovered. In this observation we have two so-called auto- matic phenomena of different types one a sensory automatism, the vision, the other a motor automa- tism or actions leading to the finding of the money. The motor acts being automatic were necessarily determined by subconscious processes and plainly required a knowledge of the hiding-place. This knowledge also plainly must have been conserved in the unconscious and now, in answer to her wish to find the lost money, acting as a subconscious proc- ess, fulfilled her wish in a practical way. The vision was of Christ smiling. Seeing it the subject at once "felt that all was well," and her anxiety vanished. It was plainly therefore a fabri- cated visual symbolism though one which she had frequently before experienced. It may be taken as a message sent by subconscious processes to her anxious consciousness and it is not too much to say had a purposive meaning, viz., to allay her anxiety. The question is, What was the causal fac- tor which determined this symbolism? Logically it is a compulsory inference that the same conserved knowledge and subconscious processes, which event- uated in the motor automatisms, must have been the causal factor that determined the visual sym- bolism which carried the reassuring message to con- sciousness. This subconscious knowledge first allayed her anxiety and then proceeded to answer her problem of the whereabouts of the lost money. 191 More specifically, the primary causal factor was the preceding anxious wish to find the money; the resulting phenomena were the sensory and motor automatisms, allaying the anxiety and fulfilling the wish; between the two as connecting links were sub- conscious processes of an intelligent, purposive, volitional character which first fabricated a visual symbolism as a message to consciousness and then made use of the conserved knowledge of her previ- ous absent-minded act to solve her problem. The subconscious process as a whole we thus see was of quite a complicated character. In this example it is impossible to determine from the data at hand whether the subconscious process was coconscious or unconscious. The observation which I have elsewhere described as "an hallucination from the subconscious " * is an excellent example of an intelligent subconscious process indicative of judgment and purpose. The hallucination occurred in my presence as a result of an antecedent experience for which I was a moment before responsible. It was therefore of the nature of an experiment and the causal factor was known. The antecedent experience consisted of certain remarks and behavior of the subject while under the influence of an illusion during a dissoci- ated state for which there was subsequent amnesia. The vision was of a friend whose face was sad, as of one who had been injured, and seemed to reproach * The Dissociation, Chapter XXXI. 192 THE UNCONSCIOUS her. At the same moment she heard his voice which said, "How could you have betrayed me?" The hallucinatory words and the visual image were in no sense a reproduction of the causal, i. e., antece- dent, experience. They were the expression of a subconscious self-reproach in consequence of that experience. This reproach connoted a subconscious belief or logical judgment, drawn from the experi- ence, that she had broken a promise.* It was a sub- conscious reaction to a subconscious belief. I say both the reproach and the judgment were subcon- scious because, in the dissociated state, owing to the illusion, and in the normal after-state owing to the amnesia, she was entirely ignorant of having done anything that could oe construed into breaking a promise. This interpretation of tlie episode must therefore have been entirely subconscious. The self- reproach emerged into consciousness but translated into visual and auditory hallucinations. These were plainly a condemnatory message sent from the sub- conscious to the personal consciousness and might aptly be termed "the prickings of a subconscious conscience." The primary causal factor was sim- ply certain statements (conserved in the uncon- scious) made to me by the subject and for which afterwards there was amnesia. Intervening be- tween this antecedent experience and the resulting hallucinatory phenomena a subconscious process must be postulated as a necessary connecting link. * As a matter of fact, the judgment was erroneous, though a justifiable inference. SUBCONSCIOUS INTELLIGENCE 193 This process plainly involved memory and an in- telligent judgment, an emotional reaction, and an expression of this judgment and reaction trans- lated into hallucinatory phenomena. Apparently also a distinct purpose to upbraid the personality was manifested. The accounts of sudden religious conversion are full of instances of hallucinations occurring at the time of the " crisis" and these visions and voices are often logical symbolisms of antecedent thoughts of the subject. By analogy with similar experimental phenomena we are compelled to inter- pret them in the same way and postulate these an- tecedent experiences as the causal factors. If this postulation is sound then the connecting subcon- scious link is often a quite complicated process of an intelligent character. In one instance in which the occurrence was simi- lar in principle to sudden religious conversion I was able to determine beyond question the causal antecedents of the hallucinatory phenomenon. I will not repeat the details here;* suffice it to say that the hallucination, consisting of a vision and an auditory message from the subject's deceased hus- band (see p. 40), answered the doubts and scruples with which the subject had been previously tor- mented. It was a logical answer calculated to allay distressing memories against which she had been fighting, "the old ideas of dissatisfaction with life, the feelings of injury, bitterness, and rebellion * Cf . The Dissociation, 2d edition, p. 567. 194 THE UNCONSCIOUS against fate and the ' kicking against the pricks' which these memories evoked." It expressed pre- viously entertained ideas which she had tried to accept but without success. The exposition of this answer in the hallucinatory symbolism required a subconscious process involving considerable reason- ing. The phenomenon as a whole was a message addressed to her own consciousness by subconscious processes to answer her doubts and anxious ques- tionings of herself, and to settle the conflict going on in her mind. The logical connection between the different elements of this hallucination and certain antecedent experiences which had harassed the sub- ject are so close that there is no room left for doubt- ing that these experiences were the causal factors. And so I might analyze a large number of spon- taneous hallucinations wherein you would find the same evidence for subconscious processes showing intelligent constructive imagination, reasoning, voli- tion, and purposive effort, and expressing them- selves in automatisms which either solve a disturb- ing problem or carry to fruition a subconscious pur- pose. I offer no excuse for multiplying tnese observa- tions of hallucinatory phenomena, even at the ex- pense of tedious repetition, for such studies give an insight into the mechanism of the hallucinations met with in the insanities and other pathological states. They offer, too, an insight into the basic process involved in dreams as these are a type of hallucinatory phenomena. It is by a study of hallu- SUBCONSCIOUS INTELLIGENCE 195 cinations experimentally created, and others where we are in a position to know the causal factors, that we can learn the mechanisms underlying similar phenomena occurring in normal pathological condi- tions. As a rule in the latter conditions it is diffi- cult to determine beyond question the true causal factors and, therefore, the particular subconscious processes involved. Such phenomena as I have presented justify the conclusion of the "new psy- chology" that the hallucinations of the insane are not haphazard affairs but the resultant of subcon- scious processes evoked by antecedent experiences. In conclusion, then, we may say that in artificial hallucinations as experimentally conducted, and in certain spontaneous hallucinations, we have two known factors; the causal factor (the antecedent ex- perience) and the hallucinatory phenomenon the effect. Intervening between the two is an inferred subconscious process of considerable complexity which is required to explain the causal connection. With the exact mechanism of hallucinatory phenom- ena we are not at present concerned, but only with the evidence of the actuality of a subconscious proc- ess, of its character as an intelligence, and with its intrinsic nature. As to the last problem it is plain that further investigations are required and that the methods at present at our disposal for its solution leave much to be desired. All things considered a conservative summing up would be that the subconscious process may be both coconscious and unconscious. 196 THE UNCONSCIOUS IV. Subconscious intelligence underlying dreams. As is well known, Freud advanced the theory, now well fortified by numerous observations of others, that underlying a dream is a subconscious process which fabricates the conscious dream. According to Freud and his followers this subconscious process is always an antecedent wish and the dream is an imaginary fulfillment of that wish. This part of the theory (as well as the universality of an under- lying process) is decidedly questionable. My own ob- servations lead me to believe that a dream may be also the expression of antecedent doubts, scruples, anxieties, etc., or may be an answer to an unsolved problem. We need not concern ourselves with this particular question here. I refer to it simply to point out that its correct solution depends upon the correct determination of the true causal factor which is necessarily antecedently unknown and must be inferred. It is inferred or selected from the asso- ciated memories evoked by the so-called method of analysis. Hence it must be always an element open to greater or less doubt. Dreams are a type of hallucinatory phenomena and therefore we should expect that their mechanism would correspond more or less closely with that of other hallucinatory phe- nomena. With the object in view of determining whether a dream could be produced experimentally and brought within the category of phenomena where the causal factor was antecedently known, and thus determine the actuality of a subconscious process as SUBCONSCIOUS INTELLIGENCE 197 a necessary intervening link between the two, I made the following experiment. It should be noted that a wish fulfilment necessarily means a dream content so far different in form from the content of the ivish itself that the postulation of a connecting link, conscious or subconscious, is required. I also sought, if a subconscious process could be postu- lated, to discover how elaborate and what sort of a work of constructive imagination a subconscious wish could evolve. To a suitable subject while in a deep hypnotic trance state I gave a suggestion in the form of a wish to be worked out to fulfilment in a dream. It so happened that this subject was going through a period of stress and strain for which she sought relief. I also knew that she had a very strong de- sire to do a good piece of original psychological work and had advised her to take up the work as a solution of her difficulties. So, taking advantage of this desire, I impressed upon her, for the purpose of emphasizing the impulsive force of the desire, that she now had the longed-for opportunity as the culmination of her previous years of training to do the work. I then gave her the following sugges- tion: "You want to do a good piece of original work and your dream to-night will be the fulfillment of the wish." No hint as to what form the dream fulfilment should take was given, nor had she any knowledge before being put into the trance state that I intended to make an experiment. It is interesting to note how the dream has a 198 THE UNCONSCIOUS logical form which is unfolded as an argument. This itself is an allegorical transcript of the rea- sons previously suggested to her for the particular solution of her problem. The dream was a long one and into it were logi- cally introduced as a part of the argument the actual distressing circumstances for the relief of which I had advised taking up the piece of psychological work as an outlet to her feelings and solution of her problem of life. I will give in detail only so much of the dream as contains the wish fulfilment (which became also a part of the dream argument), summarizing the remainder. The dream begins with an allegorical description of the great task involved in the study of psychology by all the work- ers of the world. The science of psychology is sym- bolized by a temple. "I dreamed I was where they were building a great temple or cathedral; an enor- mous place covering many acres of ground. Hun- dreds of men were building. Some were building spires, some were building foundations, and some were tearing down what they had built, some parts had fallen down of themselves. I was wandering around looking on." Then she proceeds to help one of the builders who was building a particular part of the temple by bringing him material in the form of stones. This she had actually done in real life, contributing much psychological material out of her own experiences. Many of these experiences had been very intimate ones from her inner life and had involved much suffering ; hence the stones which 199 she contributed in her dream were big and heavy and were beyond her strength to carry, so that she could only roll them, and some were sharp and made her hands bleed, so that her contribution in- volved much suffering. This part of the dream was not only a prelude to the suggested wish fulfil- ment but, as interpreted, contained a wish fulfil- ment in itself. Then there was interjected an allegorical but very accurate description of the distressing circum- stances to which I have referred and for which, as a problem of life, the suggested work was advised as a solution. Then logically followed the wish fulfilment and solution. She heard the voice of the builder whom she had been helping say to her, " 'Now, here are all the materials and you must build a temple of your own,' and I [she] said, 'I cannot, ' and he said, ' you can, and I will help you. ' So I began to build the stones I had taken him. It was hard work, but I kept on, and a most beautiful temple grew up. . . . All the stones were very brilliant in color, but each one was stained with a drop of blood that came from a wound in my heart. And the temple grew up; and I handled all the stones; but somehow the temple grew up of itself and lots of people were coming from all directions to look at it, and someone, who seemed to be William James, said, 'It is the most valuable part of the temple,' and I felt very proud. . . .' After an- other interjection of the distressing problem of her life just alluded to, the dream ends with the figure 200 THE UNCONSCIOUS of * ' a beautiful shining angel with golden spreading wings and the word 'Hope' written on his fore- head." This figure "spread his lovely wings and rose right up through the temple and became the top of the spire, a gorgeous shining figure of Hope."* After this dream was obtained the subject, who had no knowledge that any suggestion had been given to induce the dream, was told to analyze the dream herself by the method of associative mem- ories. As is customary in the use of this method, in which she had had considerable experience, the memories associated with each element of the dream were obtained. These memories all led back di- rectly to her interest in psychology and desire to contribute some original work, and to her own life 's experiences. Every one of the dream-elements (temple, spires, foundations, stones, bleeding hands, drop of blood from the wound in her heart, etc.) evoked associative memories which justified the inference that these elements were symbolisms of past experiences or of constructive imagination. * William James had once said to her in my presence that she could make a valuable contribution to psychology. It is interesting to note, although it is aside from the question at issue, that this subject had strenuously denied that there was any "hope," insisting that she was absolutely devoid of any such sentiment. Through hypnotic memories, however, I was able to demonstrate that this was only consciously true, and that there were very evident and strong coconscious ideas of hope of which she was not consciously aware. She had refused to acknowledge these ideas to herself and by repres- sion had dissociated them from the personal consciousness. These ideas now expressed themselves symbolically in the dream. SUBCONSCIOUS INTELLIGENCE 201 That this dream was determined by, and the ex- plicit imaginary fulfilment of the antecedent wish made use of in the experiment and motivated by the suggestion would seem to be conclusively shown. If, then, in any case a causal relation between an antecedent wish and its dream fulfilment exists, it follows that there must be some link between that wish experienced in the past and the present dream fulfilment, some mode, mechanism, or process by which a past thought, without entering conscious- ness, can continue to its own fulfilment in a con- scious work of the imagination, the dream. I say without entering consciousness because the original specific thought-wish does not appear in the dream consciousness, which is only the fulfilment. The phenomenon as a whole is also inexplicable unless there was some motivating factor or force which determined the form of the dream just as in con- scious fabrication and argument "we" consciously motivate and arrange the form of the product. The only logical and intelligible inference is that the original ivisli, becoming reawakened (by the preced- ing suggestion) during sleep, continued to function outside of the dream consciousness, as a motivating and directing subconscious process. But what was the content of this process, and to what extent can its elements be correlated with those of the dream? The experimental data of this dream do not afford an answer to this question. (Those of the observation I shall next give will per- mit a deeper insight into the character and content 202 THE UNCONSCIOUS of their process.) It is a reasonable inference, however, inasmuch as the different elements of the dream temple, stones, etc., the material out of which it is constructed are found to be logical sym- bolizations of their associative memories, that these memories took part in the subconscious process and consequently may be correlated with their dream- symbols. In other words the content of the subcon- scious process was more than a wish, or wish neu- rogram, it included a large complex of memories of diverse experiences that can be recognized through their symbolizations in the dream. This complex, motivated by a particular wish, fabricated the dream, just as in the hallucinations I have cited an underlying process fabricated the hallucination as a symbolic expression of a subconscious judg- ment, self-reproach, etc. To do this a process that must be termed a subconscious intelligence was re- quired. The dream was an allegory, a product of constructive imagination in the logical form of an argument, and if constructed by an underlying proc- ess the latter must have had the same character- istics.* * We must remember that a dreaming state is a dissociated state (like a fugue or trance), and numerous observations have shown that in such conditions any of the dormant related experiences of life may modify, repress, resist, alter, and determine the content of the dis- sociated consciousness. It is difficult to conceive of a dream al- legory being constructed by the dream consciousness itself. If that were the mechanism, we should expect that the associative ideas for which symbols are chosen would appear during the dream construc- tion as is the case in waking imagination. The method of the mental processes is very different in the latter. We there select from a SUBCONSCIOUS INTELLIGENCE 203 This experimental dream confirms therefore the general principle formulated by Freud from the analysis of dreams in which the causal factor is an inferred wish. It is likewise on the assumption of my having correctly inferred this factor that I have insisted that a dream may be a fabricated expres- sion of thoughts other than wishes or may be the solution of an unsolved problem. In this last case the dream phenomena and mechanism seem to be analogous in every way to the subconscious solu- tion of mathematical problems which I have already described. In such and other cases the subcon- scious process would seem to be a continuation and elaboration of the antecedent suggested problem. In dreams, then, or, as we should strictly limit ourselves for the present to saying, in certain dreams, there are, as Freud first showed, two proc- esses; one is the conscious dream, the other is a subconscious process which is the actuated resi- duum of a previous experience and determines the dream.* It would be going beyond the scope of our number of associative ideas that crowd into consciousness, choose our symbols, and remember the rejected ideas. This is not the case with dream imagination. The imagery develops as if done by some- thing else. * It must not be assumed that all dreams are determined by a subconscious process or that all are symbolic. On the contrary, from evidence in hand, there is reason to believe that some dreams have substantially the same mechanism as waking imagination subject to the limitations imposed by the existing dissociation of consciousness during sleep. Just as, in the waking state, thoughts may or may not be determined by subconscious processes, so in the sleeping state. We know too little about the mechanisms of thought to draw wide generalizations or to dogmatize. 204 THE UNCONSCIOUS subject to enter into a full exposition of this inter- pretation at this time and I must refer you for a discussion of the dream problem to works devoted to the subject. We have not, of course, touched the further prob- lem of the How: how a subconscious intelligence in- duces a conscious dream which is not an emergence of the elements of that intelligence into self-con- sciousness, but a symbolization of them. This is a problem which still awaits solution. From certain data at hand it seems likely that so far as concerns the hallucinatory perceptual elements of a dream they can be accounted for as the emergence of the secondary images pertaining to the subconscious 1 'ideas." The following observation is an example of sub- conscious versification and also of constructive imagination. It also, I think, gives an insight into the character and content of the underlying process which constructs a dream. I give the observation in the subject's own words: "I woke suddenly some time between three and four in the morning. I was perfectly wide awake and conscious of my sur- roundings but for a short time perhaps two or three minutes I could not move, and I saw this vision which I recognized as such. "The end of my room seemed to have disappeared, and I looked out into boundless space. It looked misty but bright, as if the sun was shining behind a light fog. There were shifting wisps of fog blowing lightly about, and these wisps seemed to gather into the forms of a man and a woman. The figures were perfectly clear and lifelike I recognized them both. The man was dressed in dark every-day clothes, the woman in rather flow- SUBCONSCIOUS INTELLIGENCE 205 ing black; her face was partly hidden on his breast; one arm was laid around his neck; both his arms were around her, and he was looking down at her, smiling very tenderly. They seemed to be surrounded by a sort of rosy atmosphere; a large, very bright star was above their heads not in the heavens, but just over them; tall rose bushes heavy with red roses in full bloom grew up about them, and the falling petals were heaped up around their feet. Then the man bent his head and kissed her. "The vision was extraordinarily clear and I thought I would write it down at once. I turned on the light by my bedside, took pencil and paper lying there and wrote, as I supposed, prac- tically what I have written here. I then got up, was up some minutes, went back to bed, and after a while to sleep. The clock struck four soon after getting back into bed. I do not think I experienced any emotion at the moment of seeing the vision, but after writing it down I did. "The next morning I picked up the paper to read over what I had written and was amazed at the language and the rhythm. This is what I had written : " 'Last night I waked from sleep quite suddenly, And though my brain was clear my limbs were tranced. Beyond the walls of my familiar room I gazed outward into luminous space. Before my staring eyes two forms took shape, Vague, shadowy, slowly gathering from the mists, Until I saw before me, you my Love ! And folded to your breast in close embrace Was she, that other, whom I may not name. A rosy light bathed you in waves of love ; Above your heads there shone a glowing star; Red roses shed their leaves about your feet. And as I gazed with eyes that could not weep You bent your head and laid your lips on hers. And my rent soul ' . . . [Apparently unfinished.] 206 THE UNCONSCIOUS "The thoughts were the same as my conscious thoughts had been the vision was well described but the language was en- tirely different from anything I had thought, and the writing ex- pressed the emotion which I had not consciously experienced in seeing the vision, but which (I have since learned) I had felt dur- ing the dream, and which I did consciously feel after writing. When I wrote I meant simply to state the facts of the vision."* The subject was unable to give any explanation of the vision or of the composition of the verse. She rarely remembers her dreams and had no mem- ory of any dream the night of this vision. By hyp- notic procedure, however, I was able to recover memories of a dream which occurred just before she woke up. It appeared that in the dream she was wandering in a great open space and saw this ' ' pic- ture in a thin mist. The mist seemed to blow apart" and disclosed the "picture" which was identical with the vision. At the climax of the dream picture the dreamer experienced an intense emotion well described in the verse by the unfinished phrase, "My rent soul ..." The dreamer "shrieked, and fell on the ground on her face, and grew cold from head to foot and waked up." The vision after waking, then, was a repetition of a preceding dream vision and we may safely assume that it was fabricated by the same underlying proc- * ' ' For two or three days previously I had been trying to write some verses, and had been reading a good deal of poetry. I had been thinking in rhythm. I had also been under considerable nerv- ous and emotional strain for some little time in reference to the facts portrayed in the verse. ' ' SUBCONSCIOUS INTELLIGENCE 207 ess which fabricated the dream, this process re- peating itself after waking. So far the phenomenon was one which is fairly common. Now when we come to examine the auto- matically written script we find it has a number of significant characteristics. (1) It describes a con- scious episode, (2) As a literary effort for one who is not a poetical writer it is fairly well written and probably quite as good verse as the subject can con- sciously write; (3) It expresses the mental attitude, sentiments and emotions experienced in the dream but not at the time of the vision. These had also been antecedent experiences; (4) Both the central ideas of the verse and the vision symbolically repre- sented certain antecedent presentiments of the fu- ture; (5) The script gives of the vision an interpre- tation which was not consciously in mind at the mo- ment of writing. Now, inasmuch as these sentiments and interpre- tations were not in the conscious mind at the mo- ment of writing, the script suggests that the proc- ess that wrote it was not simply a subconscious memory of the vision but the same process which fabricated the dream. Indeed, the phenomenon is open to the suspicion that this same process ex- presses the same ideas in verbal symbolism as a sub- stitution for the hallucinatory symbolism. To de- termine this point, an effort was made to recover by technical methods memories of this process ; that is to determine what wrote the verse and by what sort of a process. The following was brought out : 208 THE UNCONSCIOUS 1. The script was written automatically. The subject thought she was writing certain words and expressing certain thoughts and did not perceive that she was writing different words. ''Something seemed to prevent her seeing the words she wrote. ' ' There were two trains of ' ' thought. ' ' 2. The ' ' thoughts ' ' of the verse were in her * ' sub- conscious mind."* These " thoughts" (also de- scribed as "words") were not logically arranged or as written in the verse, but "sort of tumbled to- gether mixed up a little." "They were not like the thoughts one thinks in composing a verse." There did not seem to be any attempt at selection from the thoughts or words. No evidence could be elicited to show that the composing was done here. 3. Concurrently with these subconscious, mixed- up thoughts coconscious "images" of the words of the verse came just at the moment of writing them down. The images were bright, printed words. Sometimes one or two words would come at a time and sometimes a whole line. In other words all happened as if there was a deeper underlying process which did the composing and from this process certain thoughts without logi- cal order emerged to form a subconscious stream and after the composing was done the words of the verse emerged as coconscious images as they were * By this is meant ' ' thoughts ' ' of which she was not aware. Numerous observations on this subject have disclosed such subcon- scious ideas in connection with other phenomena. This corresponds with the testimony of other subjects previously cited. (Lecture VI.) SUBCONSCIOUS INTELLIGENCE 209 to be written. This underlying process, then, "au- tomatically" did the writing and the composing. Hence it seemed to the subject even when remem- bering in hypnosis the subconscious thoughts and images that both were done unconsciously. As to whether this underlying process was the same as that which fabricated the dream and the hallucination, the evidence, albeit circumstantial, would seem to render this almost certain. In the first place the verse was only a poetical arrange- ment of the subconscious thoughts disclosed; the vision was an obvious symbolic expression or visual representation of the same thoughts (that is, of course, of those concerned with the subject matter of the vision). The only difference would seem to be in the form of the expression verbal and visual imagery respectively.* In the second place the vision was an exact repetition of the dream vision. It is not at all rare to find certain phenomena of dreams (visual, motor, sensory, etc.) repeating themselves after waking.f This can only be ex- plained by the subconscious repetition of the dream process. Consequently we are compelled to infer the same subconscious process underlying the dream- vision. More than this, it was possible to trace * As a theory of the mechanism of the vision I would suggest that it was the emergence of the secondary visual images belonging to the subconscious ideas. t See page 102. Also Prince : The Mechanism and Interpreta- tion of Dreams. Jour. Abnormal Psychology. Oct.-Nov., 1910. G. A. Waterman: Dreams as a Cause of Symptoms. Ibid. Oct.-Nov., 1910. 210 THE UNCONSCIOUS these thoughts back to antecedent experiences of the dreamer, so that in the last analysis the dream- vision, waking- vision, and poetical expression of the vision could be related with almost certainty to the same antecedent experiences as the causal factors. Certain conclusions then seem compulsory: un- derlying the dream, vision, and script was a sub- conscious process in which the fundamental factors were the same. As this process showed itself ca- pable of poetical composition, constructive imagina- tion, volition, memory, and affectivity it was a sub- conscious intelligence. As to its intrinsic nature coconscious or uncon- conscious according to the evidence at least the process that wrote the script contained conscious elements the coconscious thoughts and images. We may assume the same for the dream and the vision. As to the mechanism of the vision it is quite conceivable, not to say probable, that, correspond- ing to the coconscious images of the printed words during the writing, there were similar images of the vision scene (both in the dream and the waking state), but these instead of remaining coconscious emerged into consciousness to be the vision.* Whether the still deeper underlying process was conscious or unconscious could not be determined by any evidence accessible and must be a matter of hypothesis. * I base this theory on other observations where coconscious images or "visions" of scenes occurred. When these images emerge into consciousness the subject experienced a vision. SUBCONSCIOUS INTELLIGENCE 211 The chief importance that attaches to this obser- vation, it seems to me, is the insight it gives into the character of the underlying process of a dream. If the conclusions I have drawn are sound, then the subconscious process which determines the con- scious dream may be what is actually an intelligence and it matters not whether a coconscious or uncon- scious one. This seems to me to be a conclusion fraught with the highest significance for the theory of dreams and hallucinatory phenomena in general. Of course we all know well enough that dissociated subconscious processes may be intelligent and influ- ence the content of the personal consciousness, as witness coconscious personalities. If the underly- ing process of a dream may be something akin to such a personality, something capable of reasoning, imagination and volition, it renders intelligible the fundamental principle of the Freudian theory of a double process the "latent" and "manifest" dream. One of the difficulties in the general ac- ceptance of this theory has been, I think, the diffi- culty of conceiving a subconscious process the ' ' la- tent dream" capable of the intelligent fabrication of a "manifest" dream phantasy which is a cryptic symbolization of the subject's thoughts. Such a fabrication has all the earmarks of purpose, fore- thought and constructive imagination. But if this underlying process can be identified, even though it be in a single case, with such an intelligence as that which wrote the poetical script we have studied, it 212 THE UNCONSCIOUS is plainly quite capable of fabricating the wildest dream phantasy. I have suggested that the subconscious intelli- gence may be comparable to the phenomenon of a coconscious personality. It is worth noting in this connection that in the case of Miss B. the cocon- scious personality, Sally, who claimed to be awake while Miss B. was dreaming, also claimed that Miss B. sometimes dreamed about what Sally was think- ing of at the moment.* In other words, the thoughts of a large systematized coconscious intelligence de- termined the dream just as these thoughts some- times emerged into Miss B.'s mind when awake. That a coconscious personality may persist awake while the principal personality is asleep I have been able to demonstrate in another case (B. C. A.). It was also noted in Dr. Barrows' case of Anna Win- sor. Moreover, Sally w r as show r n to be a persistent, sane coconsciousness while Miss B. was delirious and also while she was apparently deeply etherized and unconscious/}- After all it is difficult to distin- guish in principle the condition of sleep with a per- sisting coconsciousness from a state of deep hyp- notic trance where the subject is apparently uncon- scious. In this condition, although the waking con- sciousness has disappeared, there can be shown to be a persisting "secondary" consciousness which can be communicated with by automatic writing and which later can exhibit memories of occurrences in * The Dissociation, p. 332. f The Dissociation of a Personality, p. 330. SUBCONSCIOUS INTELLIGENCE 213 the environment during the hypnotic trance. (B. C. A.) What has been said does not touch, of course, the other mechanisms of the Freudian theory nor the unessential, greatly over-emphasized theory that the subconscious dream is always a sexual wish. On the contrary, the principle throws a strong, a priori doubt upon the correctness of this generalization. It is plainly, however, a matter of fact which might be easily determined by observation were it not for the difficulty of correctly referring clinical phenom- ena to the correct antecedent experiences as their causal factors. In the last analysis it becomes al- ways a matter of interpretation. Applied psychology. Much has been discovered in recent years regarding the part played by subcon- scious processes in the production of normal and ab- normal phenomena. But we do not as yet know the possibilities and limitations of these processes. We have as yet but an imperfect knowledge of what they can do, what they can't do, and what they do do, and of the mechanisms by which they are called into play and provoke phenomena. Many patho- logical phenomena have been shown to be due to subconscious processes ; and it is quite probable that these play an important part in determining the mental processes of normal life, but this is still largely theory. In applied psychology and psycho- pathology the "subconscious" has been made use of to explain many phenomena with which we have UNCONSCIOUS practically to deal. Assumed as a concept the phe- nomena are explained by it with a greater or less de- gree of probability. In those hysterical conditions where the subconscious processes have been shown to be split-off conscious processes, we can often re- cover memories of the latter and demonstrate their relation to the hysterical phenomena by the various technical methods already mentioned. But where this cannot be done, as is ordinarily the case, some conserved antecedent experience must be inferred as the causal factor and assumed to be the function- ing subconscious process which determines the phe- nomenon. To a large extent, then, in applied psy- chology and psychopathology the postulation in spe- cific cases of a subconscious process is theoretical and open to more or less doubt. In other words, al- though a principle may be established, its applica- tion, as in all applied sciences, is apt to meet with difficulties Now the application of the principle of a subcon- scious process to the explanation of a given phe- nomenon is rendered peculiarly difficult because for practical purposes it is not so much the question of a subacting process that is at issue as it is of what particular antecedent experience is concerned in the process. The question is of the causal factor. For example, we may know from general experience in a large number of instances that a given hysterical phenomenon a tic or a convulsive attack or an hal- lucination or a dream must be in all probability determined by a subconscious process derived from SUBCONSCIOUS INTELLIGENCE 215 some conserved experience, but what specific expe- rience may be a matter of considerable uncertainty. Hence the different theories and schools of interpre- tation that have arisen. The importance of clearly appreciating the nature of such problems and prop- erly estimating the different theories at their true value is so great that I may be permitted a few words in further explanation. Let us take dreams as a type. The conscious dream may be made up of fantastic imagery and ap- parently absurd thoughts without apparent logical meaning. Now from general experience we may believe that the dream is a cryptic symbolic expres- sion of a logical subconscious process perhaps a wish. The question is, what wish! The symbolism cannot be deciphered on its face. Now, by the an- alytic method associative memories pertaining to each element of the dream are recovered in abstrac- tion. When a memory of antecedent thoughts of which the dream element is a logical symbolism or synonym and which give an intelligent meaning to the dream is recovered, we infer that these antece- dent thoughts are contained in the determining sub- conscious process. Further, as it is found that cer- tain objects or actions (e. g., snakes, flying, etc.) fre- quently occur in the dreams of different people as symbolisms of the same thoughts, it is inferred that whenever these objects or actions appear in the dream they are always symbolisms of the same un- derlying thoughts. Obviously the mere fact of an antecedent experi- 216 THE UNCONSCIOUS ence arising as an associative memory is not of it- self evidence of its being the causal factor. Hun- dreds of such memories might be obtained. To have evidential value the memory must give logical meaning to the dream or dream element under in- vestigation. Now, as a matter of fact, more than one memory can often be obtained which answers these conditions. Consequently it becomes a mat- ter of selection from memories, or interpretation, as to which is the correct solution of a given dream problem and mutatis mutandis of a pathological phenomenon. Naturally the selection is largely de- termined by personal views and a priori concepts. It also follows that if one accepts the universality of a given symbolism and is committed to a given theory one can, by going far enough, find associa- tions in vast numbers of dreams that will support that theory. The correct solution of a dream prob- lem, that is, the correct determination of the speci- fic underlying process, depends upon the correct de- termination of the causal factor and this must be inferred. The inferential nature of the latter fac- tor therefore introduces a possible source of error. There must frequently be considerable latitude in the interpretation. This is not to gainsay that in a large number of instances the logical relation be- tween antecedent experiences (recovered by associ- ative memories) and the dream is so close and ob- trusive that doubt as to the true subconscious proc- ess can scarcely be entertained. An example of a condensed analysis of a dream SUBCONSCIOUS INTELLIGENCE 217 will illustrate the practical difficulty often presented in determining by clinical methods the correct causal factor and subconscious process of a dream. I select a simple one which consists of two scenes: * "C. was somewhere and saw an old woman who appeared to be a Jewess. She was holding a bottle and a glass, and seemed to be drinking whisky. Then this woman changed into her own mother, who had the bottle and glass, and appeared likewise to be drink- ing whisky. "Then the door opened and her father appeared. He had on her husband's dressing gown, and he was holding two sticks of wood in his hand." Before interpreting this dream I will state that the subject had been tormented (as was brought out by the associative memories) by the question whether poor people should be condemned if they yielded to temptation, particularly that of drinking. This problem she could not answer satisfactorily to herself. It is the inferred causal factor in the dream process. The dream gave an answer to this problem. Let me also point out that the material, that is, the elements out of which this dream was con- structed (indicated by the words italicized), was found in the thoughts of the dreamer on the pre- ceding day and particularly just before going to sleep. The first scene of the dream ends with the mother drinking whisky: the second scene repre- sents the father appearing with two sticks of wood. * Mechanism and Interpretation of Dreams, Journal Abnormal Psychology, Oct.-Nov., 1910. 218 THE UNCONSCIOUS For the sake of simplicity of illustration I will con- fine myself to the interpretation of this first scene as it will answer our present purposes. "As to the first scene" (by technical methods of analysis) "a rich collection of memories was obtained. It appeared that on the previous morning the subject had walked with a poor Jewess through the slums, and had passed by some men who had been drinking. This led her to think at the time of the lives of these poor people; of the temptations to which they were exposed; of how little we know of this side of life and of its temptations. She wondered what the effect of such surroundings, particularly of seeing people drinking, would have upon the child of the Jewess. She wondered if such people ought to be condemned if they yielded to drink and other temptations. She thought that she herself would not blame such people if they yielded, and that we ought not to condemn them. Then in the psychoanalysis there came memories of her mother, whose character she admired and who never condemned any one. She remembered how her mother, who was an invalid, always had a glass of whisky and water on her table at night, and how the family used to joke her about it. Then came memories again of her husband sending bottles of whisky to her mother; of the latter drinking it at night; of the men whom she had seen in the slums and who had been drinking. These, very briefly, were the experiences accompanied by strong feeling tones which were called up as associative memories of this scene of the dream. With these in mind, it is not difficult to con- struct a logical, though symbolic, meaning of it. In the dream a Jewess (not the Jewess, but a type) is in the act of drinking whisky in other words, the poor, whom the Jewess represents, yield to the temptation which the dreamer had thought of with considerable intensity of feeling during the day. The dreamer's own judgment, after considerable cogitation, had been that such people were not to be condemned. Was she right? The dream answers the question, for the Jewess changes in the dream to her mother, for whose judgment she had the utmost respect. Her SUBCONSCIOUS INTELLfGENCE 219 mother now drinks the whisky as she had actually done in life, a logical justification (in view of her mother's fine character and liberal opinion) of her own belief, which was somewhat intensely expressed in her thoughts of that morning, a belief in not con- demning poor people who yield to such temptations. The dream scene is therefore the symbolical representation and justification of her own belief,* and answers the doubts and scruples that beset her mind." Whether or not this is the correct interpretation of this dream depends entirely upon whether the true causal factors were found. If through the an- alysis this was the case, as I believe namely, the scruple or ethical problem whether poor people who yield to temptation ought to be condemned then the interpretation given is logically sound and the dream is an answer to the doubts and scruples that beset the dreamer's mind. But the answer is a pic- torial symbolism and therefore requires an inter- vening subconscious process which induces and fi- nally expresses itself in the symbolism. We may suppose that this process in response to and as a subconscious incubation of the ethical problem took some form like this: "Poor people like the Jewess are not to be condemned for yielding to the tempta- tion (of drinking) for my mother, who was beyond criticism, showed by her life she would not have con- demned them." This may or may not be the true subconscious * The symbolic expression of beliefs and symbolic answers to doubts and scruples is quite common in another type of symbolism, viz., visions. Eeligious and political history is replete with exam- ples. 220 THE UNCONSCIOUS process and the correct interpretation of the dream. But it is one possible and logical interpretation based upon the actually found antecedent experi- ences and associative memories of the dreamer. Now it so happens that this interpretation and that of other dreams * which I endeavored to trace to antecedent experiences have been warmly chal- lenged by certain clinicians because the inferred causal factors were not found to be antecedent re- pressed sexual wishes. It is insisted on theoretical grounds that the content of the dreams plainly indi- cated that there must have been such wishes and that if these had been found this dream would have been unfolded as a logical symbolical fulfilment of a sex- ual wish. Which interpretation is correct is incon- sequential for our present purpose. The contro- versy only relates to the universality of the sexual theory of dreams. The point is that this difference in interpretation shows the possibility of error in the determination of the causal factor and the sub- conscious process by clinical methods. The dream may be logically related to two or more antecedent experiences and we have no criterion of which is the correct one. To insist upon one or the other savors of pure dogmatism.! Indeed, the justification for the postulation in a dream of any subconscious proc- * Loc. cit. f It has been answered that experience in a large number of cases shows that dreams always can be related logically to sexual experi- ences. To this it may be answered they can also in an equal number of cases, indeed in many oi these same cases, be related to non-sexual experiences. SUBCONSCIOUS INTELLIGENCE 221 ess in the last analysis depends upon the sound- ness of the postulation of the antecedent experience as the causal factor. If this factor falls to the ground the subconscious process falls with it. The second point to which this discussion leads us is that the latitude of interpretation allowed by the method of analysis has given rise to different views as to the specific character of the subconscious process found in many dreams. According to the theory of Freud, to whose genius we are indebted for the discovery of this process, it is almost always a sexual wish and the dream is always the imaginary, even though cryptic, fulfilment of that wish. On the other hand, as a result of my own studies, if I may venture to lay weight upon them, I have been forced to the conclusion that a dream may be the symbolical expression of almost any thought to which strong emotional tones with their impulsive forces have been linked, particularly anxieties, apprehensions, sorrows, beliefs, wishes, doubts, and scruples, which function subconsciously in the dream. It may be a solution of unsolved problems with which the mind has been occupied,* just as in the waking state a mathematical or other problem may be solved subconsciously. In some subjects the problem is particularly apt to be one involving a conflict between opposing im- * Loc. cit. It is possible, however, that sometimes the problem has been solved subconsciously in the waking state, the answer then appearing in the dream. 222 THE UNCONSCIOUS pulses, therefore one which has troubled the dreamer.* We have seen that in experimental and spontane- ous hallucinatory phenomena, where the causal fac- tor is known, a subconscious process is the essential feature of the mechanism. In this respect the mech- anism is identical with that of certain dreams. In- deed, dreams are one type of hallucinatory phenom- ena. In fact we met with one dream the chief ele- ment of which was repeated afterward in the wak- ing state as a vision. We are justified, then, in ap- plying the principle of a subconscious process to the elucidation of the visions of normal people, although it may be difficult to determine exactly the specific content of the process and the antecedent thought from which it was derived. Sometimes the content of a vision and the known circumstances under which it occurred are sufficient to enable us to in- terpret the phenomenon with reasonable certainty. In the following historical examples it is not diffi- cult to recognize that the vision was a symbolic an- swer to a problem which had troubled the conscience of the Archduke Charles of Austria. Unable to solve his problem consciously and come to a deci- sion, it was solved for him by a subconscious proc- ess. Indeed, as a fact, the vision was accepted by Charles as an answer to his doubts and perhaps changed the future history of Austria. * Here we find an analogy with certain allied phenomena the visions and voices experienced as phenomena of sudden religious conversion. SUBCONSCIOUS INTELLIGENCE 223 "The Archduke Charles (the father of the present Emperor of Austria) was also greatly troubled in his mind as to the right to waive his claim to the crown in favor of his son. According to his own statement he only finally made up his mind when, while earnestly praying for guidance in his perplexity, he had a vision of the spirit of his father, the late Emperor Francis, laying his hand on the head of his youthful grandson and thus putting all his own doubts to rest." * The likeness in type of the dream which we have just discussed to this vision is instructive. In the former the mother of the dreamer answers the ques- tion of conscience by drinking the whisky; in the latter the father of the visualizer does the same by laying his hand on the head of the object of the doubt. I have already pointed out the evidence for a sub- conscious process underlying the hallucinatory phe- nomena of sudden religious conversion.! I may further cite here, as an analogous phenomenon, the following historical example of not only hallucina- tory symbolism, but of explicitly conscious proc- esses of thought which were elaborated by subcon- scious processes. It is Margaret Mary's vision of the Sacred Heart. Margaret earnestly desired (ac- cording to her biographer) "To be loved by God! and loved by him to distraction (aim6 jusqu'a la folie) ! Margaret melted away with love at the * Francis Joseph and His Times Sir Horace Eumbold. Page 151. (Italics mine.) t See also, ' ' The Psychology of Sudden Religious Conversion, ' ' Journal Abnormal Psychology, April, 1906, and "The Dissociation," 2nd Edit., pages 344 and 564; also James' "The Varieties of Re- ligious Experience." 224 THE UNCONSCIOUS thought of such a thing-. Like St. Philip of Neri in former times, or like St. Francis Xavier, she said to God : 'Hold back, my God, these torrents which overwhelm me, or else enlarge my ca- pacity for their reception.' " The answer and the form of the fulfilment of this wish came as an hallucination. She had a vision of Christ's Sacred Heart " 'surrounded with rays more brilliant than the sun, and trans- parent like a crystal. The wound which he received on the cross visibly appeared upon it. There was a crown of thorns round- about this divine Heart, and a cross above it.' At the same time Christ's voice told her that, unable longer to contain the flames of his love for mankind, he had chosen her by a miracle to spread the knowledge of them. He thereupon took out her mortal heart, placed it inside of his own and inflamed it, and then re- placed it in her breast, adding: 'Hitherto thou hast taken the name of my slave, hereafter thou shalt be called the well-beloved disciple of my Sacred Heart.' " * There is scarcely room to doubt, on the strength of the evidence as presented, that the antecedent longings of Margaret impelled by the conative force of their emotions were the causal factor of this vision. These longings, organized in the uncon- scious, must have gone through subconscious incu- bation (as William James has pointed out) and then emerged after maturity into consciousness as a symbolic visualization accompanied by hal- lucinatory words which were the expression of explicit subconscious imagination. Indeed, all such * Quoted by William James, page 343. SUBCONSCIOUS INTELLIGENCE 225 hallucinatory symbolisms like the mental phenom- ena in general of sudden religious conversion can only be psychologically explained as the emergence into consciousness of subconscious processes. The problem in each case is the determination of the content of the process.* Reflection, consideration, meditation. We are en- tering upon more uncertain ground in attempting to apply the mechanism of subconscious processes to every-day thought. There are certain types of thought, however, which behave as if this mechanism were at work. When, for instance, we take a prob- lem "under advisement," reflect upon it, give it ' ' thoughtful consideration, ' ' it seems as if, in weigh- ing the facts pro and con, in looking at it from dif- ferent points of view, i. e., in switching it into dif- ferent settings, in considering all the facts related to it, we voluntarily recall each fact that comes into consciousness. Yet it is quite possible, and indeed I think more than probable, reasoning from analogy, that the processes which present each fact, switch each point of view, or setting into consciousness, are subconscious and that what we do is chiefly to select from those which are thus brought into con- sciousness the ideas, settings, etc., which fulfil best the requirements of the question. In profound re- flection or attention to thought (a form of absent- * Some will undoubtedly read into Margaret's vision a cryptic sexual symbolism. To do so seems to me too narrow a view, in that it fails to give full weight to other instincts (and emotions) and to appreciate all the forces of human personality. 226 THE UNCONSCIOUS mindedness) it seems as if it were more a matter of attention to and selection from the "free associa- tions" which involuntarily come into the mind than of determining voluntarily what shall come in. If this be so, it is evident that the subconscious plays a much more extensive part in the mechanism of thought than is ordinarily supposed. We have not, however, sufficient data to allow us to do much more than theorize in the matter. Yet there are certain data which suggest the probability of the correct- ness of this hypothesis. In this connection I would point out how entirely confirmatory of this view is the testimony of the hypnotic consciousness which was cited in the previous lecture and which I will ask you to recall. You will remember that this tes- timony was to the effect that when a problem was under consideration associative memories required for its solution kept emerging out of the unconscious into the secondary consciousness.* Consider certain facts of every-day experience. A novel and difficult question is put up to us for de- cision. We have, we will say, to decide whether a certain piece of property situated in a growing dis- trict of a city shall be sold or held for future devel- opment: or a political manager has to decide whether or not to pursue a certain policy to win an election; or the President of the United States has to decide the policy of the government in certain land questions in Alaska. Now each of us would probably say that we could not decide such a ques- * Lecture VI, pp. 169-172. SUBCONSCIOUS INTELLIGENCE 227 tion offhand ; we would want time for consideration. If we attempted voluntarily, at the moment the ques- tion is put, to recall to mind all the different facts involved, to consider the given question from all as- pects, to switch the main facts into their different settings, we would find it an impossible thing to do. We consequently take the matter "under advise- ment," to use the conventional expression. We want time. Now what we apparently, and I think undoubtedly, do is to put the problem into our minds and leave it, so to speak, to incubate. Then, from time to time, as we take up the matter for considera- tion, the various facts involved in the different as- pects of the question, and belonging to their differ- ent settings, arise to mind. Then we weigh, com- pare, and estimate the value of these different facts and arrive at a judgment. All happens as if sub- conscious processes had been at work, as if the prob- lem had been going through a subconscious incuba- tion, switching in this and switching in that set of facts, and presenting them to consciousness, the final selection of the deciding point of view being left to the latter. The subconscious garners from the store" house of past experiences, those which have a bear- ing on the question and are required for its solution, brings them into consciousness, and then our logical conscious processes form the judgment. The degree to which subconscious processes in this way take part in forming judgments would vary according to the mental habits of the individual, the complexity of the problem, the affectivity and conflicting char- 228 THE UNCONSCIOUS acter of the elements involved. Under this theory we see that there is a deeper psychological basis for the every-day practice of taking "under advise- ment" or "into consideration" a matter, before giving judgment, than would appear on the surface. There is considerable experimental evidence in fa- vor of this theory. In discussing above the subcon- scious solution of problems I cited certain evidence, obtained from the memories of subjects in hypnosis, for coconscious and unconscious processes taking part in such solutions. I have been able to accumu- late evidence of this kind showing the cooperation of processes outside of consciousness in determining the point of view and final judgment of the subject when a matter has been under advisement ; particu- larly when the subject has been disturbed by doubts and scruples. It is plain that in the final analysis any question on which we reserve our judgment is a problem which we put into our minds. And, after all, it is only a question of degree and affectivity be- tween the state of mind which hesitates to decide an impersonal question, like a judicial decision, and one that involves a scruple of conscience. This latter state often eventuates in hallucinatory and other phenomena involving subconscious processes. Scru- ples of conscience, it is true, usually have strong af- fective elements as constituents, but the former may also have them, particularly when involving per- sonal ambitions, political principles, etc. LECTURE VIII THE UNCONSCIOUS Our studies up to this point have led us to the general conclusion that a large measure of the ex- periences of life are conserved or deposited in what may be called a storehouse of neurographic dispo- sitions or residua. This storehouse is the uncon- scious. From this storehouse our conscious proc- esses draw for the material of thought. Further, a large amount and variety of evidence, which we have briefly and incompletely reviewed, has shown that conserved experiences may function without arising into consciousness, i. e., as a subconscious process. To what extent such processes take part in the mechanism of thought, contribute to the for- mation of judgments, determine the point of view and meaning of ideas, give direction to the stream and formulate the content of consciousness, and in particular conditions, by a species of translation, manifest themselves consciously as phenomena which we designate abnormal constitute special problems which require to be studied by themselves. Physiological memory and processes. There is one phase of the unconscious which for the sake of com- 229 230 THE UNCONSCIOUS pleteness ought to be touched upon here, particu- larly as it is of considerable importance in any bio- logical conception of intelligence. There is every reason to believe that intrinsically there is no essen- tial difference between those physiological disposi- tions and activities of the lower nervous centers (subcortical ganglia and spinal cord), which condi- tion and determine unconscious behavior, and those dispositions and activities of the higher centers the cortex which condition and determine both con- scious and unconscious behavior. The former are undoubtedly innate in that they are primarily condi- tioned by inherited anatomical and physiological prearrangements of neurons and the latter are pre- eminently acquired through experience although probably not wholly so. (Our knowledge of the localization of function in the nervous system is not sufficiently definite to enable us to delimit the locali- zation of either innate or acquired dispositions.) The innate activities of the lower nervous centers so far as represented by movements can be clearly dif- ferentiated from those of the higher centers and recognized in the behavior of so-called ' ' spinal ' ' an- imals and of animals from which the cerebral hemi- spheres have been removed. In the former the con- nection between the spinal cord and all parts of the nervous system above having been severed, what- ever movements are executed are performed by the spinal cord alone and therefore of course by uncon- scious processes. The latter animals, although their actions are more complex and closely approximate THE UNCONSCIOUS 231 (with important differences) those of normal ani- mals, are also devoid or nearly devoid of conscious- ness. I say ''nearly devoid" because in the inter- pretation of the experiments it is difficult to dis- prove that, as some hold, elementary sensations qua sensation are retained, though others regard the animals as purely unconscious physiological ma- chines. In the spinal animal, in response to specific stim- uli, various movements are elicited which though of a purposive character are effected, as has been so admirably worked out by Sherington, by complex spinal mechanisms of a reflex character. The so- called ' ' scratch reflex ' ' and the reflex movements of walking, trotting, and galloping (the animal being suspended in air) are examples. Such reflexes in- volve not only the excitation of certain movements appropriate to the stimulus but the inhibition of an- tagonistic muscles and reflex movements. Further in the integration of the spinal system, reflexes are compounded, one bringing to the support of an- other allied accessory reflexes so that various co- operative movements are executed. A constellation of reflexes leads to quite complex spinal mechanisms responsive to groups of stimuli acting concurrently and resulting in behavior which is purposive and adaptive to the situation. The neural processes ex- ecuting such movements are necessarily conditioned by inherited dispositions and structural arrange- ments of the neurons. In the animal from which the cerebral hemi- 232 THE UNCONSCIOUS spheres only have been removed there can be little doubt that the physiological mechanisms governing behavior differ only in complexity, not in kind, from those of the spinal reflexes ; that in passing through successive anatomical levels from the spinal animal to this decerebrate animal with the addition of each successive ganglion the increasing complexity of be- havior corresponds to increasing complexity of mechanisms or compounding of reflexes. And yet in the decerebrate animal without consciousness, as we must believe (excepting perhaps elementary sensa- tions), the subcortical ganglia and spinal cord con- tinue to perform exceedingly complex actions ordi- narily, as we suppose, guided in the normal animal by consciousness. The reptile crawls; the fish swims; indeed the lancet fish has no brain, all its functions being regulated by its spinal cord. The frog hops and swims; the hen preens its feathers, walks and flies; the dog walks and runs. These, however, are the simplest examples of decerebrate behavior. Indeed it may be quite complex. The more recent experiments of Schrader on the pigeon and falcon and Goltz and Rothmann on the dog, not to mention those of earlier physiologists, have shown that the decerebrate unconscious (?) animal performs about all the movements performed by the normal animal.* "A mammal such as a rab- bit, in the same way as a frog and a bird, may * For a general account of the behavior of decerebrate animals and summary of these experiments see Loeb 'a ' ' Physiology of the Brain," and Schafer's Text Book of Physiology. THE UNCONSCIOUS 233 in the complete or all but complete absence of the cerebral hemispheres maintain a natural posture, free from all signs of disturbance of equilibrium, and is able to carry out with success at all events all the usual and common bodily movements. And as in the bird and frog, the evidence also shows that these movements not only may be started by, but in their carrying out are guided by and coordinated by, afferent impulses along afferent nerves, including those of the special senses. But in the case of the rabbit it is even still clearer than in the case of the bird that the effects of these afferent impulses are different from those which result when the impulses gain access to an intact brain. The movements of the animal seem guided by impressions made on its retina, as well as on other sensory nerves; we may perhaps speak of the animal as the subject of sensa- tions; but there is no satisfactory evidence that it possesses either visual or other perceptions, or that the sensations which it experiences give rise to ideas." * Even spontaneity which at one time was supposed to be lost it is now agreed returns if the animal is kept alive long enough. It "wanders about in the room untiringly the greater part of the day" (Loeb). Of course there are differences in the animal's be- havior when compared with normal behavior, but these differences are not so easy to interpret in psy- chological terms. Loeb, apparently following * M. Foster: A Text Book of Physiology, 1895, page 726. 234 THE UNCONSCIOUS Schrader, does not believe the animal is blind or deaf or- without sensation for it reacts to light, to noise, to smell, to tactile impressions, etc. It avoids obstacles and is guided by visual impressions, etc. The falcon jumps at and catches a mouse introduced in its cage; the dog growls and snaps if its paw is pinched and endeavors to get away or bite the of- fending hand; the pigeon flies and alights upon a bar, apparently visually measuring distance, and so on. But though it is guided by visual and other sen- sory impressions, does it have visual, auditory and other images, that is, conscious sensory states f This is not easy to answer. It certainly acts like an ani- mal that is not blind nor deaf nor without tactual sensation, and yet it is conceivable that it is guided simply by sensory mechanisms without conscious sensation. The main reason, apparently, for believ- ing the animal to be without sensation, as some be- lieve (e. g., Morgan) is the absence of the cerebral cortex in which alone sensation is believed to be "lo- calized. ' ' Eecently Eothmann * has succeeded in keeping alive for three years a dog from which the entire cerebrum was extirpated. It was then killed. Although the dog, like Goltz' dog, in its behavior exhibited an abundance of functions in the spheres of mobility, sensibility, feeding, barking, etc., Eoth- mann came to the conclusion that it was blind and * Von M. Eothmann : Demonstration des Hundes ohne Gross- irn. Sericlit uber den V Kongress f. Experiment. Psychol. in Ber- lin, 1912, page 256. The report is too meager to admit of independ- ent judgment of the animal 's behavior in many of ita details. THE UNCONSCIOUS 235 deaf.* Although apparently without taste for bit- ter, sweet, sour, and acid, yet the dog reacted differ- ently to edible and non-edible substances, swallowing the former and rejecting the latter (moist sand) ; raw flesh was eaten preferably to cooked flesh and Goltz' dog rejected from its mouth food made bit- ter with quinine. Some kind of gustatory processes (probably purely reflex as in Pawlow's association experiments) were therefore retained though not necessarily taste as such. But blindness and deaf- ness in the dog cannot negative the retention in birds and other animals of visual and auditory im- pressions of some kind which guide and originate behavior. But whether such impressions are psy- chologically sensations or not, the animal certainly does not possess visual or other perceptions, be- cause the "sensations" have no "meaning." Schrader's falcon, for example, would jump at and catch with its claws a moving mouse in the cage, but there the matter was at an end; it did not devour it as would a normal falcon. Any moving object had for it the same meaning as a mouse and excited the same movement. So the decerebrate dog does not distinguish friend from stranger and other dogs have no meaning for it. All objects are alike to all decerebrate animals. In the popular language of the street "all coons look alike" to them. In other * Until the basal ganglia have been microscopically examined it cannot be determined that the loss of function was not due to sec- ondary organic lesions. In Goltz' dog, which acted like a blind dog, one optic nerve was cut and the corpora striata and optic thalami were partly involved in the lesion. 236 THE UNCONSCIOUS words the main defect is loss of memory for con- scious experiences, of what Loeb calls associative- memory, the conscious memory which gives meaning to sensations, transforms them by synthesis into perception of objects and gives still further mean- ing to the objects. Hence for the pigeon without its cerebrum "Everything is only a mass in space, it moves aside for every pigeon or attempts to climb over it, just as it would in the case of a stone. All authors agree in the statement that to these animals all objects are alike. They have no enemies and no friends. They live like hermits no matter in how large a company they find themselves. The lan- guishing coo of the male makes as little impression upon the female deprived of its cerebrum as the rat- tling of peas or the whistle which formerly made it hasten to its feeding place. Neither does the female show interest in its young. The young ones that have just learned to fly pursue the mother, crying unceasingly for food, but they might as well beg food of a stone." * One of the chief utilities of conscious memory is the means it offers the psycho-physiological organ- ism to make use of past experiences to adapt present conduct to a present situation. This the brainless animal cannot do. Hence it is a mindless physio- logical automaton. All the actions performed by it, however complex they may be, are unquestionably performed and primarily conditioned by inherited neural arrangements and dispositions. They may * Quoted from Schrader by Loeb. THE UNCONSCIOUS 237 be even regarded as complexly compounded reflex processes similar excepting in complexity, as Sher- rington has held, to the mechanisms of the spinal cord. The behavior of the animal is therefore by definition instinctive. But even so this fact in no way throws light upon the intrinsic nature of the physiological process, but only upon the conditions of its occurrence. Acquired behavior is also condi- tioned conditioned by acquired dispositions. The difference physiologically between the two is that in instinctive behavior the neural processes are con- fined to pathways established by evolutionary de- velopment, and in acquired behavior to pathways established by experience. Both must be condi- tioned by pathways, and the process in its inner na- ture must be the same in both. Many cortical proc- esses, to be sure, are conscious i. e., correlated with consciousness but probably not all. And this quality of consciousness permitting of conscious memory is of great utility in the organization of ac- quired dispositions that provide the means for the adaption of the animal to each new environmental situation. Furthermore, it is not at all certain that the be- havior of the decerebrate animal is not in part de- termined by secondarily acquired dispositions. In the normal animal instinctive actions become modi- fied and perfected after the very first performances of the act by conscious experience * and it is not at all certain that dispositions so acquired and essen- * Cf . Lloyd Morgan: Instinct and Experience, 1912. 238 THE UNCONSCIOUS tial for these modifications are not conserved and incorporated in the unconscious neural arrange- ments of the subcortical centers. So far as this may be the case the acquired modifications of instinctive behavior may be manifested in the actions of the de- cerebrate animals. In other words, the unconscious processes of the lower nervous centers motivating movements (and visceral functions) may include acquired dispositions or physiological memories. That the subcortical centers are capable of mem- ory seems to have been shown for the first time by Eothmann's dog. This mindless animal proved to be capable of a certain amount of education. It learned to avoid hitting against objects, and to do certain tricks jumping over a hurdle and follow- ing on its hind legs a stool upon which its fore feet were placed as the stool was dragged forward. * ' In the perfection of all these performances the influ- ence of practice was easily recognized." This means, if the interpretation given is correct, that new dispositions and new connections may be ac- quired within the lower centers without the inter- vention of the integrating influence of the cortex or conscious intelligence.* This is an important con- tribution for apparently the attempt to educate brainless animals had not been previously made, and their capability for education demonstrated. The important bearing which this fact has upon * Dr. Morgan in his work, ' ' Instinct and Experience, ' ' 1912, pub- lished before Kothmann 's observations, remarks that this ' ' is not in- herently improbable" although it had not as yet been demonstrated. THE UNCONSCIOUS 239 this discussion is that it shows that unconscious proc- esses are capable of memory, that is physiological memory. It may be said that this statement needs some modification if the sensory "impressions" guiding the decerebrate animal are to be interpreted as true psychological, however elementary, "sensa- tions." It would seem to me on the contrary only to accentuate the fact that the processes of the brainless animal are on a transition level between the purely unconscious processes of the spinal ani- mal and the purely (if ever wholly so) conscious processes of the normal animal, and that intrinsi- cally all are of the same nature. If sensation en- ters into the complex reflex reactions of the brain- less animal it would seem that it can only be an ele- mental conscious factor in a complicated uncon- scious physiological mechanism. In this mechanism it can have no more specific importance in deter- mining behavior, because of the fact of its being a psychological state, than if it were a receptor "impression" intercalated in the arc of an innate process. It is not linked with any associative mem- ories of the past or foresight into the future ; it does not constitute conscious intelligence. As a con- scious experience it cannot have that kind of "mean- ing" which in the normal animal modifies instinc- tive processes and determines conduct. It prob- ably plays simply the same part in the whole proc- ess, which otherwise is wholly unconscious, that the associative sensory image plays in determining the flow of thick or thin saliva in Pawlow's dogs sim- 240 THE UNCONSCIOUS ply a single link in a chain of associated reflex proc- esses. The next point to which I would direct attention is that from an objective point of view the behavior of the decerebrate animal may be in nature intelli- gent in the empirical sense of that word. The dog that growls and snaps when his foot is pinched, tries to draw it away, and, failing that, bites at the offending hand; the "educated" dog that jumps over a hurdle, and walks on his hind legs, following a stool supporting his front legs, to my way of think- ing performs intelligent actions whether it has a brain or not. If intelligence is arbitrarily limited to actions performed by conscious processes, then in- telligence becomes a mere question of terms.* * From the point of view here adopted, the recent discussions and controversies over the problems of ' ' instinct and intelligence ' ' have been much muddled by the arbitrary denial of conscious elements to an instinctive process, and by the acceptation of consciousness or conscious experience as the criterion of intelligence. In this view instinct and intelligence become contrasted concepts which to my way of thinking they are not necessarily at all. If it is admitted that instinct is an innate disposition, its contrasted quality is that which is acquired and not the quality of consciousness. It is true that acquired behavior is commonly if not always determined by con- scious processes (conscious experience), but likewise innate behavior may be determined by processes which contain conscious elements. Surely fear is instinctive and is a conscious element in an innate process; and so must be visual and other sensory images, as in the first peck of a chicken. To look upon the first visual image simply as conscious "experience," as an "onlooker," and reject it as a factor in the process which determines that first peck, seems to me to be arbitrary psychology if not physiology. If consciousness may be a quality of an innate process and why not? it cannot be a THE UNCONSCIOUS 241 There arises also the practical difficulty that certain types of behavior, which by common assent and com- mon sense are regarded as purely automatic and unintelligent, must be termed intelligent because guided by consciousness. I cannot help thinking that " intelligence " is a pragmatic question, not a biological or psychological one. It would be much more conducive to a clear understanding of bio- logical problems to use intelligence only as a con- venient and useful expression, like sanity or in- sanity, to designate certain behavior which conforms to a type which, without strictly denning its limits, popular language has defined as intelligent. San- ity and insanity have ceased to be terms of scientific value because they cannot be defined in terms of specific mental conditions and much less in terms of mental processes. So intelligence cannot be de- criterion of intelligence. The true converse of the conscious is the unconscious. This adopted antithesis between consciousness and instinct, from this point of view as well as the arbitrary limitation of the localiza- tion of the whole of an instinctive process to the subcortical centers, vitiates the force of the very able presentation of the subject by Dr. Morgan, if I correctly understand him. I know of no data which forbid the cortex to be included in the innate mechanism of an in- stinctive process. On the contrary, it is difficult to understand in- stinctive behavior and its modifications through conscious experience unless cortical centers are included in the psycho-physiological arcs. At any rate we may define instinct and intelligence in terms of the conscious and the unconscious, or in brain terms, but we should not mix up these aspects with that of localization in the definition. Mr. McDougall 's conception of instinct appeals to me more strongly from both a biological and a psychological point of view, and further seems to me to be more in consonance with the data of experience. 242 THE UNCONSCIOUS fined in terms of conscious and unconscious proc- esses. Any attempt to do so meets with insuperable difficulties and becomes "confusion worse con- founded." When we say then that the behavior of the decerebrate dog may be intelligent, all that is meant is that the animal exhibits behavior identical with that which in the normal animal we would em- pirically call intelligent. In this sense unconscious processes may exhibit intelligence. It was from this viewpoint, I think, that Foster concluded: "In short, the more we study the phenomena exhibited by animals possessing a part only of their brain, the closer we are pushed to the conclusion that no sharp line can be drawn between volition and lack of volition, or between the possession and absence of intelligence. Between the muscle-nerve prepara- tion at one limit, and our conscious willing selves at the other, there is a continuous gradation without a break; we cannot fix on any linear barrier in the brain or in the general nervous system, and say 'beyond this there is volition and intelligence, but up to this there is none. ' " * It has already been pointed out (Lecture V) that, in man, complicated actions which have been voli- tionally and perhaps laboriously acquired may be afterwards involuntarily and unconsciously per- formed, f In other words, after intelligent actions * A Text Book of. Physiology, 1893, page 727. f The localization of the processes concerned in all such acquired automatic behavior whether it is in the cortex or subcortical cen- ters is an unsolved problem. THE UNCONSCIOUS 243 have been acquired by conscious processes, they may be performed by subconscious processes for which there is no conscious awareness and probably these may be either coconscious or entirely unconscious. There is no sharp dividing line between the activities of the unconscious, coconscious, and conscious. When we descend in the scale of animal life to the insects (bees, ants, etc.,) we observe motor activity of a highly complex character of a kind that is termed intelligent, but we are forced to conclude, from various considerations, that the elements of consciousness have dwindled away to what can be nothing more than mere sensibility. In other words consciousness is reduced to its lowest terms, but behavior and the neural processes are maintained at a high level of complexity. Accordingly there is a disproportion between the complexity of the mo- tor behavior and the inferred simplicity of con- sciousness, for in the higher animals the former would be correlated with complex psychological processes. If this be so, the motor activities must be determined by processes which are mostly uncon- scious. In still lower forms of life the motor activities can be referred to simple tropisms, and thus necessarily are wholly unconscious. Between the most complex unconscious physio- logical processes performed by the nervous system and the simpler cerebral processes accompanied by consciousness there is not as wide a step as might seem when superficially viewed. The physiological 244 THE UNCONSCIOUS process may, as we have seen, manifest itself in acts of quite as intelligent a character as those ex- hibited by the conscious process, and indeed more so ; for the conscious act may be little more than a limited reflex. On the other hand a psychological process may be so elementary that it contains noth- ing of awareness of self, of intelligence, or of voli- tion in the true sense nothing more, perhaps, than an elementary sensation without even perception. But it may be said that the presence of the most rudimentary state of consciousness makes all the difference and renders the gulf between the two impassable. We are not called upon to discuss that question here. It is one which involves the ultimate nature of physical processes. A distinction should be made between psychological and psychical, these not being coextensive and always interchangeable terms. Psychological pertains to the empirical data of con- sciousness, (thoughts, ideas, sensations, etc.) while psychical pertains to the inner or ultimate nature of these data. Though the data as given in con- sciousness are psychical, that which is psychical may not be solely manifested as psychological phenom- ena. It may be manifested as physical phenomena and perhaps be identified with the energy of the universe. Hence the doctrine of panpsychism. And so it may be that in its ultimate analysis an uncon- scious process is psychical (monism) although not psychological and not manifesting itself as a datum of consciousness. Certain it is that, objectively THE UNCONSCIOUS 245 viewed, there is nothing to distinguish physiologi- cal from psychological intelligence. If the extraor- dinary instinctive habits exhibited by insects, such as bees and ants and by still lower forms of animal life, can rightly be interpreted as, in large part at least, manifestations of physiological processes, as is quite possible, the distinction between the con- scious and the unconscious in respect to intelligence and adaptability to environment would be reduced to one only of degree. That some of the lowest forms of life are endowed with consciousness, in any sense in which the word has psychological meaning, seems incredible, though they manifest instinctive intelligence of no mean order. The fact probably is, as I have just intimated, that those processes we call physiological and those we call psychological are in their inner nature identical, and the former are quite capable of functioning, incredible as it may seem, in a fashion that we are accustomed to believe can only be the attribute of conscious intelli- gence. This does not mean, of course, that the phy- siological intelligence can reach the same degree of perfection as that reached by conscious intelligence, though conversely, the latter may be of a lower order than physiological intelligence.* From this point of view we are logically entitled to regard * If the subconscious processes which perform a mathematical cal- culation and other problems, which logically determine the symbolism of a dream, etc., can be correctly interpreted as unconscious, they plainly exhibit a higher order of intelligence than any conscious processes in lower animals, or even some conscious processes of man, like brushing away a fly. 246 THE UNCONSCIOUS physiological processes, even of the lower nervous centers and even though they are not acquired but due to congenital structural and functional arrange- ment, as phases of the unconscious. Psycho-physical parallelism and monism. According to the doctrine of psycho-physical parallelism every mental process is correlated with (accompanied by) a brain process. As brain processes thus viewed are "unconscious" (in the sense of not having the attribute of consciousness) we may express this in other terms and say: every "conscious" process is accompanied by an "unconscious" process. I have no intention of entering here into the question of the validity of the doctrine of psycho-physical parallelism. I wish merely to point out that if parallelism is a true formulation of the mind- brain problem, as I have just stated it, the con- verse ought to hold true, namely, that every brain process of a certain kind involving intelligence ought to be correlated with consciousness. But if some subconscious processes manifesting what is equivalent to thought, reasoning, judgment, imagina- tion, volition, etc., are unconscious as seems likely if not probable then this converse does not hold true. This has some bearing on the validity of the doctrine ; for if physical processes can perform sub- stantially the same function as conscious intelli- gence it is difficult to reconcile this fact with what I may call naive psycho-physical parallelism. It is reconcilable, however, with psychic monism. THE UNCONSCIOUS 247 According to this doctrine it is not a question of parallelism at all. There is only one process the psychical. The physical brain process is only an aspect or special mode of apprehending this one. All is psychical but not psychological. That which we apprehend in the form of the unconscious is really psychical and hence is capable of performing the same kind of function as it performs when it becomes psychological. It is not at all certain that unconscious processes may not comprise an intelli- gence possessing faculties identical in kind with those of conscious intelligence and indistinguisha- ble from the latter. Subconscious processes may exhibit perception, cognition, reason, imagination, conation (will), feeling, etc., and it is possible that some of these processes may be correctly inter- preted as unconscious. At any rate, from the point of view of monism, whether the real psychical proc- ess or, probably more correctly, how much of it shall emerge as a psychological state of conscious- ness depends upon intrinsic conditions. Though we cannot penetrate within them it is quite conceivable that it is a matter of complexity of synthesization and cooperative activity of psychical energies. This is a most interesting problem closely related to that of awareness and self-consciousness. The meanings of the unconscious, subconscious, and co- conscious. Though the term "unconscious" is in general use it has so many connotations derived from its various meanings in metaphysics, psychol- 248 THE UNCONSCIOUS ogy, and physiology that its use has given rise to considerable confusion of thought, particularly, I am compelled to believe, in the interpretation of specific psycho-physiological phenomena. Nevertheless, it has been so well established in our nomenclature that we could not replace it if we would. Nor is it wholly desirable to do so. It is a good and useful term, but I believe that with each advance in the pre- cision of our knowledge we ought, so far as accumu- lative data permit, to give precision to the concept for which it stands. Just as in physical science we attempt to give precision to our concept of elec- tricity in conformity with new data accumulated from time to time, so our psychological concepts should be defined and limited in accordance with the advance in knowledge. Some do not like to define the term, not being quite willing to commit themselves unreservedly to the complete acceptance of the physiological theory of memory and to cut adrift from the metaphysical concept of a sublimi- nal mind. If the psycho-physiological theory of memory, which is now generally accepted, is sound, we have one meaning of the unconscious which is a very definite concept, namely, the brain residua, physiological " dispositions" or neurograms in which the experiences of life are conserved. These terms become, therefore, synonyms for the uncon- scious. That, under certain conditions, the passive neurograms may, under stimulation, become active and function unconsciously (i. e., without corre- sponding psychological equivalents being introduced THE UNCONSCIOUS 249 into the personal consciousness), need not invali- date the concept. We are then dealing with an un- conscious and dynamic process. The effects of such functioning are simply the manifestations of the unconscious and may be recognized either in modi- fications of the stream of consciousness or in bodily disturbances. The term unconscious is an appro- priate and descriptive term to characterize that which is devoid of the attributes of consciousness. This use of the term has been sanctioned by com- mon usage. Unfortunately, however, the term has been also employed to characterize another and distinct class of facts, namely Co-[or Sub-] conscious Ideas. We shall have occasion to study these psychological phenomena in other lectures.* We have seen ex- amples in many of the phenomena I have cited. It is sufficient to say here, that as conceived of, and as we have seen, they are very definite states of cocon- sciousness a coexisting dissociated consciousness or coconsciousness of which the personal conscious- ness is not aware, i. e., of which it is ''unconscious." Hence they have been called ''unconscious ideas" and have been included in the unconscious, particu- larly by German writers. But this is plainly using the term in a different sense using it as a synonym for the longer phrase, "ideas we are unaware of," and not as a characterization of that which is physi- ological and non-psychological. "Unconscious ideas" in this sense (the equiva- * Not included in this volume. 250 THE UNCONSCIOUS lent of coconscious ideas) would include conscious states that we are not aware of simply because not in the focus of attention but in the fringe of the content of consciousness. The term would also in- clude pathologically split-off and independently act- ing coconscious ideas or systems of ideas such as occur in hysteria, reaching their apogee in cocon- scious personalities and in automatic writings. Here we have a series of facts essentially different from the conceptual facts of physical residua, the form in which experiences are conceived to be con- served. Manifestly it is confusing and incorrect to define both by "the unconscious." And to speak of the former as "unconscious ideas" and of the latter as "unconscious," although technically cor- rect, leads to confusion from using the term "un- conscious" in two different senses.* As a concept in a scheme of metaphysics, "un- conscious ideas" i. e., ideas of which we are not conscious, have long been recognized. Leibnitz was the first to maintain, on theoretical grounds and by a priori reasoning, the existence of ideas of which we are not aware, as did likewise Kant, influenced by Leibnitz, and later Schilling, and Herbart; while Hartmann evolved the unconscious into a biological and metaphysical system, f * It has been objected that to speak of unconscious ideas is a contradiction of terms. This seems to me to smack of quibbling as we know well enough that the adjective is used in the sense of un- awareness. f For a good account of the history of the theory of unconscious ideas in philosophy see Hartmann 's "Philosophy of the Uncon- THE UNCONSCIOUS 251 By most American, English, and French psychol- ogists such ideas, as conceived at least by Leibnitz, Kant, and Herbart, would to-day be called sub- conscious or coconscious ideas. Hartmann included all physiological processes of the nervous system in the Unconscious and ascribed to them special attributes (will, purpose, etc.). The Unconscious accordingly has connotations from which it is not easy to rid ourselves in dealing with it. It is gen- erally agreed that it is desirable to have a term which shall cover all classes of facts coconscious ideas, conserved experiences, and physiological proc- scious, ' ' where the following quotations may be found : "To have ideas and yet not to be conscious of them there seems to be a con- tradiction in that for how can we know that we have them if we are not conscious of them? Nevertheless, we may become aware in- directly that we have an idea, although we be not directly cognizant of the same." (Kant, Anthropology, sec. 5.) And again: " In- numerable are the sensations and perceptions whereof we are not conscious although we must undoubtedly conclude that we have them, obscure ideas as they may be called (to be found in animals as well as in man). The clear ideas, indeed, are but an infinitely small fraction of these same exposed to consciousness. That only a few spots on the great chart of our minds are illuminated may well fill us with amazement in contemplating this nature of ours. (Ibid.) "Now unconscious ideas" are such "as are in consciousness without our being aware of them" (Herbart). It is interesting to notice how Kant's statement might well be substituted for that of Myers' of his "Subliminal." It is difficult to understand the peculiar antagonistic attitude of certain theoreti- cal psychologists to the theory of subconscious (coconscious) ideas in view of the history of this theory in philosophy. They seem to have forgotten their philosophy and not to have kept pace with ez- perimental psychology. 252 THE UNCONSCIOUS esses without committal of opinion as to inter- pretation.* It does not follow, however, that the term " un- conscious" is the one that should be chosen. On the contrary, as unconscious has two distinct and different meanings (that pertaining to unawareness and that which is non-psychological) it is a very undesirable term if we wish to be precise in our terminology. That we should have a term which shall precisely define ideas which are not in awareness and which shall distinguish them from physiological processes is necessitated by the fact that such ideas in themselves form a distinct field of investigation. The term "subconscious" is commonly used, ex- cepting by German writers, to characterize these co- conscious ideas. In fact, by some French medical writers, particularly Janet, it is very precisely limited to such ideas. By other authors it is em- ployed in this sense and also to include the physical residua of experiences, and sometimes with the addi- tional meaning of unconscious physiological neuro- grams, or processes, which it defines in fact, to denote any conserved experience or process outside of consciousness. On the other hand, among these authors, some do not admit the validity of the con- cept of coconscious ideas, but interpret all so-called subconscious manifestations as the expression of the physiological functioning of physiological neu- rograms in which the experiences of life are con- served. Subconscious and unconscious are, there- * See footnote on p. 149. THE UNCONSCIOUS 253 fore, quite commonly, but not always, employed as synonyms to define two or three different classes of facts. For practical reasons, as already stated, it is desirable to have a term which shall embrace all classes of facts, and of the two terms in com- mon use, subconscious and unconscious, the former is preferable, as it is not subject to the double mean- ing above mentioned. I, therefore, use the term subconscious in a generic sense to include (a) cocon- scious ideas or processes; (b) unconscious neuro- grams, and (c) unconscious processes. Of course it is only a matter of terminology. The conceptual facts may then be thus classified : T (synonym : The coconscious J subconscious ideas.) a : Conserved dormant neurograms or neural dispositions. The subconscious < The unconscious b: Active functioning neurograms or neural processes. (synonym: unconscious processes.) 254 THE UNCONSCIOUS Subconscious as an adjective used to qualify ideas is plainly equivalent to coconscious ideas. This terminology I have found useful in keeping the dif- ferent classes of conceptual facts separate in my mind and I believe it will prove to be equally useful to others. With the conceptual facts clearly differ- entiated it will be generally easy to recognize the various senses in which the terms are used when found in the writings of others. The unconscious as a fundamental of personality. A survey of all the facts and their relations, which I have outlined in the preceding lectures, brings into strong relief the important principle that no matter in what state complexes of ideas are formed, so long as they are conserved, they become a part of our personality. They become dormant, but, being conserved, they may under favorable conditions be awakened and enter our conscious life. It matters not whether complexes of ideas have been formed in our personal consciousness, or in a state of hypno- sis, in dreams, in conditions of dissociated person- ality, in coconsciousness, or any other dissociated state. They all become parts of ourselves and may afterwards be revived under favoring conditions, whether volitionally, automatically, by artificial de- vices, by involuntary stimuli, or other agencies. They may or may not be subject to voluntary recall as recollections, but, so long as they form part of our dormant consciousness as physiological neuro- grams, they belong to the personal self. ''After THE UNCONSCIOUS 255 all, ' ' as Miss B. used to say, and correctly, referring to her different dissociated personalities, BI, B III, and BIV, "after all, they are all myself." It makes no difference in what state an experience has occurred. A potential memory of it may persist and may, in one way or another, be revived, no matter how or when it originated. Through the conception of the subconscious as resolvable, on the one hand, into the imconscious, passive or active physiological dispositions, and, on the other hand, into coactive conscious states, the subconscious becomes simplified and intelligible. It offers a basis on which may be constructed compre- hensible theories of memory, suggestibility, post- hypnotic phenomena, dreams, automatic writing and similar phenomena, artificial hallucinations, the protean phenomena of hysteria, and the psycho- neuroses, as well as the mechanism of thought. It enables us also to construct a rational concept of personality and self. As we shall see, when we take up the study of multiple personality in later lectures, out of the aggregate of the accumulated and varied experience of the past conserved in the unconscious may be constructed a number of different person- alities, each depending upon a synthesis and rear- rangement of life's neurograms and innate disposi- tions and instincts. All dormant ideas with their feeling tones and conative tendencies belong to our personality, but they may be arranged with varying instincts and innate dispositions into a number of differentiated systems, each synthesized into a cor- 256 THE UNCONSCIOUS responding personality. In the unconscious may be conserved a vast number of life's experiences ranging in time almost from the cradle to the grave. The hopes, the wishes, the anxieties of childhood may still be there, lying fallow, but capable of in- jecting themselves under favoring conditions into our personalities. Properly speaking, from this point of view, aside from certain artificial and path- ological conditions, there is, normally, no distinct "subconscious self," or "subliminal self," or "sec- ondary self," or "hidden self." In artificial and pathological conditions there may be, as has been frequently shown, a splitting of consciousness and the aggregation into a secondary coconscious sys- tem of large systems of ideas which have all the characteristics of personality. This secondary per- sonality (of which the primary personality is not aware) may have its own memories, feelings, per- ceptions, and thoughts. It may appropriate to itself various complexes of neurograms deposited by the experiences of life which are not at the disposal of the principal personality. Such a coconscious sys- tem may properly be spoken of as a subconscious self. But there is no evidence that, normally, such systems exist. All that we are entitled to affirm is that every individual's consciousness may include ideas of which he is not aware, and that he has at his disposal, to a greater or less extent, a large unconscious storehouse in which are neurographi- cally conserved a large and varied mass of life's experiences. These experiences may be arranged THE UNCONSCIOUS 257 in systems, as we shall see in the next lecture, but they do not constitute a "self." To speak of them as a subconscious, subliminal, secondary, or hidden self is to construct concepts which are allegories, metaphors, symbolisms, personifications of concrete phenomena. Their use tends to falla- cious reasoning and to perverted inductions from the facts. Becoming major premises in a syllo- gism they lead to erroneous interpretations of the simplest facts, just as fixed ideas or obsessions tend to a perverted interpretation of the environ- ment. We are now in a position to see that the psycho- physiological theory of memory has a far-reaching significance. The facts which have been brought before you in evidence of the theory have been selected largely from those which were capable of verification by experimentation and by other objec- tive testimony. They include a large variety of ex- periences which occurred in pathological conditions like amnesia and multiple personality, and in arti- ficial conditions like hypnosis and intoxication. Such abnormal conditions enable us to show by tes- timony, independent of the individual, that these experiences had actually occurred, and, therefore, to show that the reproductions of these experiences were in principle truthful memories. They also enable us to appreciate the enormous variety and quantity of experiences which, although absolutely beyond the power of voluntary recall, may be con- served nevertheless as neurograms, and also to ap- 258 THE UNCONSCIOUS predate the minuteness of detail in which the brain records may be preserved. If you will stop a moment to think, and give play to your imagination, you will see that the principle of the neurographic conservation of experiences must be true not only of our outer life, of our ex- periences with our environment, but of our whole inner life, normal as well as abnormal. It is always possible that any thought, any feeling, however trivial and transitory, may leave neurograms in the brain. It is always possible that even a fleeting doubt or scruple, thoughts which flash into the mind and straightway are put out again, all may leave their records and dispositions to function again. Even a passing doubt which any of you may enter- tain regarding the interpretation of the phenomena I have described, and the correctness of our con- clusions, may be recorded. Indeed, it is a matter of some importance for the understanding of ob- normal mental conditions that many of those horrid little sneaking thoughts which we do not like to admit to ourselves, the thoughts which for one rea- son or another we endeavor to repress, to put out of our minds, may leave their indelible traces. In fact, these are the very thoughts, the ones which we try hardest to forget, to push aside, which are most likely to be conserved. The harder we try, the stronger the feelings attached to them, the more likely they are to leave neurograms in the brain though they may never be reproduced. This has been shown by observation of pathological condi- THE UNCONSCIOUS 259 tions, like hysteria and psychasthenia, and by ex- perimentation. In repressing our thoughts we do not put them out of our minds, but, as the subject previously cited, who in hypnosis could recall such repressed thoughts, said, we put them into our minds. In other words, we conserve them as neurograms. In one sense, I suppose, we may say that every one leads a double life. Let me hasten to say to you, I mean this not in a moral but in an intellectual sense. Every one's mental life may fairly be said to be divided between those ideas, thoughts, and feelings which he receives from and gives out to his social world, the social environment in which he lives, and those which belong more properly to his inner life and the innermost sanctuary of his per- sonality and character. The former include the activities and the educational acquisitions which he seeks to cultivate and conserve for future use. The latter include the more intimate communings with himself, the doubts and fears and scruples pertain- ing to the moral, religious, and other problems of life, and the struggles and trials and difficulties which beset its paths ; the internal contests with the temptations of the world, the flesh, and the devil. The conventionalities of the social organization re- quire that the outward expression of many of these should be put under restraint. Indeed, society in- sists that some, the sexual strivings, are aspects of life and human nature which are not to be spoken or thought of. Now, of course, this inner life must also leave its neurographic tracings along with the 260 THE UNCONSCIOUS outer life, and must, potentially at least, become a part of our personality, liable to manifest itself in character and in other directions. But, more than this, abnormal psychology, through its technical methods of investigation and through the perverted manifestations exhibited in sick conditions of mind and body, has shown us that the neurograms de- posited as the experiences of this inner life may flower, to use an expression of the lamented William James, below the threshold of consciousness, and, under certain conditions, where the mind is in un- stable equilibrium, burst forth in mental and bodily manifestations of an unusual character. Thus in processes of this kind we find an explanation of religious phenomena like sudden conversion; of dreams and of certain pathological phenomena like the hallucinations, deliria, crises, and bodily mani- festations of hysteria, and the numerous automatic phenomena of spiritualistic mediums. Such phe- nomena may then be interpreted as the flowering or functioning of the unconscious. The essential difference in the consequences which follow from this psycho-physiological conception of memory, based as it is on the unconscious, and those which follow from that conception which is popu- larly held must be obvious. According to popular understanding the mental life which we have out- lived, the life which we have put behind us, whether that of childhood or of passing phases of adult life, is only an ephemeral, evanescent phase of conscious- ness which once out of mind, put aside or forgotten, THE UNCONSCIOUS 261 need no longer be taken into consideration as per- taining to, much less influencing, our personality. Writers of fiction who undertake to depict human nature almost invariably, I believe, are governed by this point of view. They describe their characters as throwing overboard their past, their dominating beliefs, convictions, and other traits as easily as we should toss undesirable refuse into the ocean. Their heroes and heroines jettison their psychologi- cal cargoes as if they were barrels of molasses when- ever their personalities show signs of going down in the storms of life's experiences. According to this view, which is derived from an imperfect con- ception of mental processes, any passing phase of consciousness ceases to have potential existence or influence as soon as it is forgotten, or as soon as it ceases to be a consciously dominating belief or motive of life. It is assumed that so long as we do not bring it back into consciousness it belongs to us no more than as if it had originated in the mind of another, or had taken flight on the wings of a dove. This is true in part only. A phase of consciousness may not be conserved, or it may be- come so modified by the clash with new experiences that a rearrangement of its elements takes place and it becomes, for instance, a new motive or belief, or a new setting to give a new meaning to an idea. On the other hand, any passing phase may, as we have seen, still belong to our personality even though it lies hidden in its depths. That we no longer recall it, bring it voluntarily into the field of our personal UJNUOJNSUIOUS consciousness, does not negative its continuing (though dormant) existence, and its further influ- ence upon the personality through the subconscious workings of the mind. In conclusion, and by way of partial recapitula- tion, we may say, first: The records of our lives are written in unconscious dormant complexes and therein conserved so long as the residua retain their dynamic potentialities. It is the unconscious, rather than the conscious, which is the important factor in personality and intelligence. The unconscious furnishes the formative material out of which our judgments, our beliefs, our ideals, and our char- acters are shaped. In the second place, the unconscious, besides being a static storehouse, has dynamic functions. It is evident that, theoretically, if unconscious complexes are once formed they may, under favoring condi- tions of the psycho-physical organism, become re- vived and play an important part in pathological mental life. If through dissociation they could be freed from the normal inhibition and the counter- balancing influences of the normal mental mechan- ism, and given an independence and freedom from voluntary control, they might, by functioning, pro- duce abnormal states like fixed ideas, delusions, au- tomatisms, hallucinations, etc. A study of such ab- normal phenomena confirms this theoretical view and finds in this conception of the unconscious an explanation of the origin of many of them. The hallucinations and bizarre notions and delusions of THE UNCONSCIOUS 263 the insane, the hysteric, and psychasthenic, where all seems chaos, without law or order, are often due to the resurrection and fabricating effect of uncon- scious complexes formed by the earlier experiences of the patient's life. Of course, the mechanism by which such phenomena are produced is a compli- cated one about which there is much difference of opinion and which we cannot enter into here. In post-hypnotic phenomena and artificial hallucina- tions we have experimental examples of the principle. More than this, and more important, there is con- siderable evidence going to show that conserved ex- periences functioning as subconscious processes take part in and determine the conscious processes of everyday life. On the one hand stored neurograms may undergo subconscious incubation, assimilating the material deposited by the varied experiences of life to finally burst forth in ripened judgments, be- liefs, and convictions, as is so strikingly shown in sudden religious conversions and allied mental manifestations. Through a similar incubating proc- ess, the stored material needed for the solution of baffling problems is gathered together and often- times assimilated and arranged and formulated as an answer to the question. On the other hand, sub- conscious processes may be but a hidden part of that mechanism which determines our everyday judgment and our points of view, our attitudes of mind, the meanings of our ideas, and the traits of our characters. Antecedent experiences function- 264 THE UNCONSCIOUS ing as such processes may determine our fantasies and our dreams. Thus functioning as dynamic proc- esses the stored residua of the past may provide the secrets of our moods, our impulses, our preju- dices, our beliefs, and our judgments. It remains, however, for future investigation to determine the exact mechanism and the relative ex- tent to which subconscious processes play their parts. LECTURE IX THE ORGANIZATION OF UNCONSCIOUS COMPLEXES Everyday life It will be well at this point to state in orderly fashion a few general principles govern- ing the organization of complexes or syntheses of ideas * which, as we shall see, play an important part in normal and abnormal life. Although this statement will be little more than descriptive of w r hat is common experience it will be helpful in clas- sifying and obtaining a useful perspective of the phenomena with which we shall deal. Now, as every one knows, the elemental ideas w r hich make up the experience of any given moment tend to become organized (i. e., synthesized and con- served) into a system or complex of ideas, linked with emotions, feelings and other innate disposi- tions, so that when one of the ideas belonging to the experience comes to mind the experience as a whole is recalled. We may conveniently term such a sys- tem when in a state of conservation, an unconscious * I am using this word in the general sense of any mental ex- perience as in the common phrase, "the association of ideas," and not in the restricted sense of Titchener as the equivalent of a percep- tion. 265 266 THE UNCONSCIOUS complex * or neurogram, or system of neurograms. If we wish to use psychological terms we may speak of it as a complex or synthesis of dormant ideas. Although we may formulate this principle as the " association of ideas" the formula can have only a descriptive significance pertaining to a relation in time (and not a causal one) unless there be included an unconscious factor by which the association be- comes effective in exciting one idea through another i. e., through a linking of neural dispositions. We cannot conceive of any conscious relation between ideas that can possibly induce this effect. It must be some unconscious dynamic relation f and be ex- plained in terms of neural dispositions. If this be so, all ideas are dynamically associated and related in a process which does not appear in consciousness and which is essential for organization into a com- plex. Every system of associated ideas, therefore, implies conservation through an organized uncon- scious complex. Complexes may be very feebly organized in that the elemental ideas are weakly conserved or weakly associated; in which case when we try to recall the original experience only a part or none of it is re- called. On the other hand, a complex may be strongly * I use this word ' ' complex ' ' in the general sense in which it is commonly used and not with the specific meaning given to it by the Zurich school, which limits it to a system of ideas to which a strong affective tone is attached and which, because of its personally dis- tressing character, is repressed into the subconscious. I Which may be psychical, although not psychological. UNCONSCIOUS COMPLEXES 267 organized and include a large number of de- tails of an experience. This is usually owing to the fact that the original experience was accom- panied by strong emotional tones, or by marked in- terest and attention, or was frequently repeated. Emotional Complexes: 1. When the original experi- ence was accompanied by an emotion it may be regarded as having excited one or more of the emo- tional instincts of anger, fear, disgust, etc. The ex- citation of the instinct or instincts is in one sense a reaction to the ideas of the experience. The instincts then become organized about one or more of the ideas to form a sentiment (Shand) and the whole is incorporated in a complex which then acquires an affective character. The impulsive force of the in- stinct thereafter largely determines the behavior of the complex. (To this we shall return later when we consider the instincts.) General observation shows that emotional experiences are more likely to be conserved and also voluntarily recalled. Given such an emotional complex nearly anything asso- ciated with some detail of the experience may, by the law of association, automatically or involun- tarily revive it, or the emotional reaction with a greater or less number of its associated memories. This tendency seems to be directly proportionate to the intensity of the instinct (fear, anger, etc.) incor- porated in the complex. Sometimes, it is true, a strongly emotional experience, even an experience of great moment in an individual's life, is completely 268 THE UNCONSCIOUS forgotten, so completely that no associated idea avails as a stimulus to awaken it. Usually in all such cases the neurograms are isolated, etc., by dis- sociation. They still, however, may be strongly or- ganized and conserved as an unconscious complex and sometimes may be excited as a subconscious process by an associated stimulus. In such condi- tions it very frequently is found that the dissocia- tion is due to conflict between the emotion belonging to the complex and another emotional complex. The impulsive force of the latter dissociates the former complex which then cannot be voluntarily repro- duced as memory, nor awakened by any association under normal conditions. We have then a condition of amnesia and often an hysterical condition. To this important phenomenon we shall return when we consider the emotions. Passing over these ex- ceptional conditions of conflicting emotions (which being explained " prove the rule"), it still remains true that in everyday life emotional experiences are not only more likely to be conserved but to be sub- ject to voluntary recall, or awakened involuntarily by an associated stimulus. If, for instance, we have experienced a railroad accident involving exciting incidents, loss of life, etc., the words "railroad," "accident," "death," or a sudden crashing sound, or the sight of blood, or even riding in a railroad train may recall the ex- perience, or at least the prominent features in it. The earlier events and those succeeding the accident may have passed out of all possibility of voluntary UNCONSCIOUS COMPLEXES 269 recall. To take an instance commonplace enough, but which happens to have come within my recent obser- vation: a fireman, hurrying to a fire, was injured severely by being thrown from a hose-wagon against a telegraph-pole with which the wagon collided. He narrowly escaped death. Although three years have elapsed he still cannot ride on a wagon to a fire without the memory of substantially the whole acci- dent rising in his mind. When he does so he again lives through the accident, including the thoughts just previous to the actual collision when realizing his situation he was overcome with terror, and he again manifests all the organic physical expressions of fear, viz., perspiration, tremor, and muscular weakness. Here is a well organized and fairly limited complex. It is also plainly an imperative memory, that is to say, any stimulus-idea associated with some element in the complex reproduces the experience as memory whether it is wished or not. Try as hard as he will he cannot prevent its recur- rence. The stimulus that excites such involuntary memories may be a spoken word (as in the psycho- galvanic and other associative experiments which we shall consider in a later lecture), or it may be a visual perception of the environment of a person or place or it may be a repetition of the circum- stances attending the original experience, however induced. The phenomenon may also be regarded as an automatism or automatic process. As the biologi- cal instinct of fear is incorporated in the complex it is also a phobia. 270 THE UNCONSCIOUS Why our fireman suffered the intense terror that he did at the time of the accident, why he experi- enced the thoughts which surged into his mind, why he suffered this emotional experience, while another man going through the same accident suffers no more than the physical injury (if any) at the time, and why the experience continues to recur as an imperative memory are problems which we are not considering now. The fact is that he did suffer the terror and its agonizing thoughts, and, this being the case, their constant recurrence, i. e., the repro- duction of the experience, is a memory. And this memory consists of a well organized complex of ideas, feelings, and physiological accompaniments. I emphasize this point because an imperatively re- curring mental experience of this sort is a psychosis, and, so far as the principle of memory enters into it, so far memory becomes a part of the mechanism of obsessions. The reason why the man at the moment of the accident experienced the terrorizing thoughts that he did, and why he continued to experience them, must be sought in associated conserved experiences of his past. These experiences were the psycho- genetic factors. It would take us too far out of the way to consider this problem, which belongs to the obsessions, at this time, but, as I have touched upon it, I may say in passing that the accident would have awakened no sense of terror and no emotional shock if a psychological torch had not already been pre- pared. This torch was made up of ideas previously UNCONSCIOUS COMPLEXES 271 imbibed from the social environment and made ready to be set aflame by the match set to it by the accident. In the unconsciousness of this man were written in neurographic records the dangers attend- ing accidents of this kind and dangers which still threatened his present and future. Likewise the insistence of the memory can be re- lated to a setting of associated thoughts which gave meaning to his perception of himself as one affected, as he believed, with a serious injury threatening his future. His fear was also, therefore, a fear of the present and future. Thus not only the experiences of the accident itself became organized into a group and conserved as a memory, but were organized with memories of still other experiences which stood in a genetic relation to them. If it were necessary I could give from my personal observation numerous ex- amples of this mode of organization of complexes through emotional experiences and of their repro- duction as automatic memories. An historical example of complex-organizing of this kind is narrated in Tallentyre's delightful life of Voltaire. Toward the end of Voltaire's famous residence at the court of Frederick the Great, as the latter 's guest, one of those pestiferous friends who cannot help repeating disagreeable personal gossip for our benefit swore to Voltaire to having heard Frederick remark, "I shall want him (Vol- taire) at the most another year; one squeezes the orange and throws away the rind. ' ' From that mo- 272 THE UNCONSCIOUS ment a complex of emotional ideas was formed in Voltaire's mind, that, do what he would, he could not get rid of. He wrote it to his friends, thought about it, dreamed about it ; he tried to forget it, but to no purpose; it would not ''down"; the rind kept constantly rising. It brought with it every memory of Frederick's character and actions that fitted the remark. Voltaire, like many men of genius, was a neuras- thenic and his ideas with strong emotional tones tended to become strongly organized and acquire great force. ' ' The orange rind haunts my dreams, ' ' he wrote ; * * I try not to believe it. ... We go to sup with the king and are gay enough sometimes; the man who fell from the top of a steeple and found the fall through the air soft and said, 'Good, provided it lasts,' is not a little as I am." The emotional complex which so tormented Voltaire that it literally became an obsession was a recurring memory. The experience had been strongly registered and con- served, owing to the emotional tone, but the reason why there was so much emotion, and why it ab- sorbed so many associated ideas into itself and kept recurring would undoubtedly have been found to lie, if we could have probed Voltaire's mind, in its settings his previous stormy experiences with Frederick, his knowledge of Frederick's character, his previous apprehensions of what later actually occurred, and, most probably, self-reproach for his own behavior, the consequences of ivhich he feared to face. All this, conserved as neurograms, was set UNCONSCIOUS COMPLEXES 273 ablaze by the remark and furnished not only the emotion but the material for the content of the complex. These previous experiences, therefore, stood in genetic relation to the latter, excited the emotional reaction of anger, resentment and fear, and prevented the complex from subsiding. The ex- citing cause for each recurrence of the complex was, of course, some associated stimulus from the envi- ronment, or train of thought. Another interesting historical example is the fool- ish complex which is said to have disturbed the pretty Mme. Leclerc (Pauline Bonaparte, who was afterward the Princess Borghese). This fascinat- ing and beautiful woman was enjoying her triumph at a ball. Seated in a little boudoir off the ball- room she was entertaining "guests who came to admire her and fill her cup to overflowing. There was, however, a Mme. de Contades, who had been deserted by her own cavaliers at the appearance of Pauline. Approaching, now. on the arm of her escort, she said in a tone sufficiently loud so that every one, including Pauline, could hear perfectly: 'Mon Dieu, what a misfortune! Oh, what a pity! She would be so pretty but for that!' 'But for what?' asked her cavalier. All eyes were turned upon poor Mme. Leclerc, who thought there must be something the matter with her coiffure and began to redden and suffocate. 'But do you not see what I mean?' persisted Mme. de Contades, with the cold cruelty of a jealous woman. 'What a pity! Yes, truly, how unfortunate ! Such a really pretty 274 THE UNCONSCIOUS head to have such ears ! If I had ears like those I would have them cut off. Yes, positively, they are like those of a pug dog. You who know her, Mon- sieur, advise her to have it done ; it would be a char- itable act.' Pauline, more beautiful than ever in her blushes, rose, tears blinding her eyes, then sank back upon the sofa, hiding her face in her hands, sick with mortification and shame. As a matter of fact, her ears were not ugly, only a little too flat. From that day, however, she always dressed her hair over them or concealed them under a bandeau, as in the well-known painting of her. ' ' * Fixed ideas relating to physical blemishes are not uncommonly observed as obsessions in psychasthen- ics. With our knowledge of such psychical manifes- tations it is easy to imagine Pauline's antecedent thoughts regarding her own flat ears, and repug- nance to this defect in others, her suspicions of un- favorable criticisms and of not being admired, etc., all organized with the instinct of self-abasement (emotion of subjection) and forming a sentiment of self-depreciation and shame in her mind. 2. The outbreak of such automatic memories is particularly prone to occur in persons of a particu- lar temperament (the apprehensive temperament, in which the biological instinct of fear is the paramount factor), in fatigue states, and in so-called neurotic people neurasthenics, psychasthenics, and hyster- ics. In such people the organization of the complex probably has been largely a previously subcon- * Sisters of Napoleon, by M. Joseph Turquan. UNCONSCIOUS COMPLEXES 275 scious incubating process, as in the phenomenon of 1 'sudden religious conversion." Later the sudden suggestion or awakening by whatsoever means of an idea, which has roots in the antecedent thoughts engaged in the subconscious process, readily gives occasion for the outbreak of the complex. The lat- ter then excites the emotional reaction of anger, hor- ror, antipathy, fear, jealousy, etc., which becomes incorporated in the complex. When once formed the automatism becomes the psychosis. The following case is an illustration : L. E. W., forty-nine years of age, farmer and lawyer by occupation, a man of strenuous disposi- tion, broke down under stress and strain with severe but common symptoms of mental and physical fatigue modified and exaggerated by apprehensions of incurable illness. At the end of a year there developed scruples and jealous suspicions of his wife's chastity, not persistent but recurring from time to time in attacks, and always awakened by a suggestion of some kind an associated idea, a remark heard, an act of some kind on the part of the wife, etc. Between the attacks he was entirely free from such thoughts, but during the attack, which came on with the usual suddenness, these thoughts always the same doubts, suspicions, rea- sonings, jealousy, and fear were dominating, im- perative, and painful. An open-minded, frank, in- telligent man he fully realized that his scruples were entirely unfounded and even chara'cterize'd them as 276 THE UNCONSCIOUS ' ' delusions. ' ' It was interesting, so clear was he in this respect, to hear him discuss his attacks between times with his wife, as if they were recurrent appen- dicitis. The attacks would pass off in a short time after discussing his scruples with his wife, and then he became natural again ; they involved great suffer- ing and he feared, as people thus afflicted so often do, that they spelled impending insanity. And yet it was easy to determine that they were only impera- tive recurrent memories, conserved complexes emerging from the unconscious. He had been mar- ried twenty- two years. He was of a jealous nature, and before marriage it annoyed him to think that his wife had been courted by other men, that she wrote them letters, etc. He began to think of her as a flirt, that she was going to jilt him, and to have misgivings of her character. He grew jealous and suspicions of possible unchastity worried him, but reasoning with himself he would say, ' ' 0, pshaw ! it is an abominable suspicion," "an hallucination," and put the thought out of his mind, as he said. But we know he really put the thought into his mind to be conserved in the unconscious, as a com- plex of chastity scruples, and there undergo incuba- tion and further development. Later he had had spells of jealousy during his married life but no true imperative ideas until he broke down in health, and then, as he himself expressed it, "the devil got the upper hand and said, ' I Ve got you now. ' ' ' The devil was the complex organized twenty-two UNCONSCIOUS COMPLEXES 277 years previously with the emotion of jealousy * cen- tered about the idea of his wife and the whole neu- rographically conserved. The impulsive force of the emotion was constantly striving to awaken and give expression to the unconscious complex. He was able to hold it in check, to repress it, by the conflicting force of other sentiments until these be- came weakened by the development of the psychas- thenic state. Then these latter controlling elements of personality were repressed in turn whenever the more powerful jealousy complex was awakened. The whole mechanism was undoubtedly more com- plicated than this, in that the jealousy complex had a setting in certain unsophisticated and puritanical ideas of conduct (brought to light in the analysis) which gave a peculiar meaning (for him) to his wife's actions. So long as this setting persisted it would be next to impossible to modify the jealousy complex. "Whatever the mechanism, ideas with strong emotional tones (particularly fear, anger, jealousy, and disgust), no matter how absurd or repellent, or unjustified, and whether acceptable or unacceptable, tend to become organized and welded into a com- plex which is thereby conserved. The impulsive force of the incorporated emotion tends to awaken and give expression to the complex whenever stimu- lated. The recurrence of such an organized complex * McDougall (Social Psychology) regards jealousy as a complex emotional state in which anger, tender emotion, and other innate dispositiens are factors. 278 THE UNCONSCIOUS so far as it is reproduction is, of course, in principle, memory, and an imperative memory or fixed idea. Whether the complex shall be awakened as such a recurrent memory, or shall function as a dissociated subconscious process, producing other disturbances, or remain quiescent in the unconscious, depends upon other factors which we need not now consider. 3. Clinically the periodic recurrence of such com- plexes is an obsession. An obsession as met with is most likely to be characterized by fear not only be- cause the instinct of fear is the most painful of the emotions, but for another reason. Although biologi- cally fear is useful as a defense for the preservation of the individual, when perverted by useless associa- tions it becomes harmful, in that it is not only pain- ful but prevents the adjustment of the individual to his environment and thereby takes on a pathological taint. Complexes with other emotions are less likely to be harmful and therefore less frequently apply for relief. Yet imperative ideas with jealousy, anger, hatred, love, disgust, etc., centered about an object are exceedingly common though their pos- sessors less often resort to a physician. From another point of view abnormal complexes, represented by these examples, may be regarded as
