BY JAMES EDWIN CREIGHTON, A.B. THE WILL 4-^^ ITS STRUCTURE AND MODE OF ACTION. BY JAMES EDWIN CREIGHTON, A.B. printed by Andrus & Church, ITHACA, 1898. Cb 42974 1 PREFACE. This essay was written during the summer of 1891, while I was a student in the University of Berlin, and presented to the Faculty of Cornell University as a thesis for the doc- torate in the spring of 1892. At that time I hoped to be able to return to the subject and make what I had done the basis for a more extensive investigation. The press of other engagements and duties has, however, prevented me from carrying out this plan, and the essay is now published in the form in which it was first written. I have added one or two foot-notes while reading the proofs, but made no other altera- tions, though if I were writing today I should doubtless lay different emphasis upcn certain points. My interest in the subject of the Will was due mainly to the psychological writings of Wundt, James, and Miinster- berg, and my treatment owes much to each of these writers. My other obligations I have tried to acknowledge in full throughout the essay itself. J. E. C. TABIvE OF CONTENTS. Chapter I. The Concept of W11.1., PAGE 7 Chapter II.

It is of the utmost importance to attempt, first of all, to define the conceptions which are to form the subject of our study. What do the terms ' Will ' and ' Willing ' signify ? The extension of these terms have varied widely, as is well known, with different authors. With many writers ' Will ' is only used to denote a conscious choice between alternative directions of activity, and is predicated only of such individ- uals as are capable of representing to themselves such possi- bilities.^ Other philosophers widen the conception by omit- ting from it the element of consciousness, and that of repre- sentation of alternatives, and thus extend the notion of will, so as to make it synonymous with force or energy in general. In this broader sense of the word. Will is predicable not only of persons, but also of all phenomena of the Universe, and of the Universe itself as a whole.^ Between these extreme limits, we find various definitions and uses of the term, as one or other of the elements constituting the concept has been em- phasized or removed.^ As for the last mentioned theory, that of Schopenhauer and his school, we can only protest against such a confusion of ideas under one term. We know ' Will ' only through our own immediate experience, and as an element of our con- scious life ; and, as thus known, consciousness, not less than force, is always an element of the empirically given fact. To quote from Sigwart : "From this point of view an uncon- scious Will is a contradictio in adjecto. It may be believed ^ Martineau, A Study of Religion, I. p, 198 ; II. p. 188. Sigwart, Kleine Schriften, Vol. II, p. 118 ff. ' Schopenhauer, Die Welt als Wille. Werke, II, pp. 113 ff. ' For various uses, see Martineau, Study of Religion, II., p. 188. 8 The Will. that unconscious activities take place, and have the same re- sults as those which we call will ; we may perhaps even be justified in calling these activities Will in a wider sense, but only because we have first learned to know a conscious Will ; and it will always be safer to choose for the broader concept another term. " ^ On the other hand, it seems to me that the notion of will as a separate Faculty has tended to unduly limit the notion. The old Psychology regarded the activities of the self as manifested through a number of ' Faculties ' such as Think- ing, Perceiving, Willing, etc. It was too often forgotten that these faculties were not each sui generis^ and that they indi- cated nothing in themselves apart from the nature of the con- scious processes. Apart from the definite content of con- sciousness, the universal form of activity is only an abstraction which leads us astray and defies treatment. As a result of the same separation, too, a large part of our mental life was con- ceived as going on without any relation to the Will. It was sup- posed that ordinarily the Associative process, with its own pe- culiar laws, sufficed to explain mental occurrences. But at cer- tain points, more or less frequent in the life of the individual, the Will as a kind of miraculous function, as a power of an al- gether new and unique nature, was supposed to intervene and to prove its superiority to the ordinary Associative law^s, by subordinating them to its commands, or reversing their di- rection. Modern psychologists, on the other hand, refuse to make this sharp and absolute distinction between Will and the other processes of the mental life. They lay emphasis upon the fact that in " all sensation, all Association and Comparison a constant cooperation of the Will also takes place. " ^ " Asso- ciation, " says Wundt, '* is only the reflex of that central unity of our consciousness which we immediately perceive in ^ Kleine Schriften, II., p. ii6. ' Green, Prolegomena to Ethics, Sec. 132. The Concept of Will. 9 the inner and outer activity of the Will. " ^ Thinking, Per- ceiving, etc., are different names which signify the employ- ment of this activity in different spheres, and npon different kinds of subject matter. We may name all psychical activity, all influence which the self exerts upon the course of events. Will i7i the broader sense of the term. In so far as the self asserts itself against inner or outer events, and modifies, or strives to modify them, it may be said to will. But, it may be asked, why should the other psychical activities be subsumed under willing ? The answer to this question is to be found in the fact which will be emphasized throughout this essay, that the will pro- cess has really its root in the selective activity of attention. And it is true that this activity finds employment in the con- struction of our perceptive world, and in the formation of our concepts and judgments regarding it, no less than in effecting changes in the stream of thought, or in bodies lying external to us. Our perceptive world, the world with which we come into immediate contact in every day experience, is the result of choosing, out of the infinite variety of things by which we are surrounded, some objects which are to us particularly in- teresting. As no two men's interests are exactly identical, the worlds in which they live can not be absolutely identical. The painter's world is more rich in beautiful forms and colors than that of the ordinary man ; the musician detects in the moaning of the wind harmonies that are lost on an ear less sensitive. The scientist's perceptive world is made up of a variety of details which simply do not exist for the ordinary man. The influence of the attention in constituting and de- termining our world for us is plainly seen as we pass from 1 Grimdzuge d. Physiol. Psychologic, ist Aufl. p. 726 ; Cf. also Hoffding Outlines of Psychology {'Bng. trans.) pp. 314: " It is not enough to say- that will precedes cognition and feeling, for these latter, looked at one from one side, are themselves manifestations of will in the Mdder sense." V lo , The Will. childhood to manhood. I was very much interested lately in walking with a little boy to find that the things he saw were almost entirely different from those which made an impres- sion upon me. Talking to him afterwards of what he had seen, I found that the objects of his experience, what he had actually seen and remembered, were things which are prac- tically absent for the ordinary adult. This fact of the selective function of the will in perception is well illustrated by Professor James : " Let four men make a tour in Europe. One will bring home only picturesque im- pressions of costumes and colors, parks and views and works of architecture, picture and statues. To another all this will be non-existent ; distances and prices, populations and drain- age statistics will take their place. A third will give a rich account of the theatres, restaurants, and public halls and naught beside ; whilst the fourth will perhaps have been so wrapped in his own subjective broodings as to tell little more than a few names of places through which he passed. Each has selected out of the same mass of presented objects those which suited his private interests, and has made his experi- ence thereby." ^ Leaving now this field of perception, and coming to what is usually regarded as the higher mental activities, we find that they, too, manifest to a striking degree the selective ac- tivity of the self. Concepts are formed from percepts by abstraction, and attention. That is, the concept-process con- sists in picking out from a variety of percepts, those which seem to us, in accordance with our interests or practical needs, to be the most essential attributes of the things presented to us. The elements thus selected are bound together by means of a common name. While thus essentially individual in their nature, the common or universal aspect of concepts is intelligible from the fact that human beings, as members of the same world, have to a large degree the same practical Principles of Psychology, Vol. I, p. 286. The Concept of Will. ii needs. Reasoning, again, may be described as a selection of one out of many conceptions each of which stands in subordin- ation to a higher, and of that particular one which will serve as a connecting link between that higher and some lower concept or individual with which our practical interests lead us to connect it. Thus in the syllogism, M is P, Sis M, Sis P, what we done is to select from the numerous notions which are comprehended in P, the appropriate one Mhy means of which S can be brought into relation with P} But not only this formal process of reasoning, but the very content of one's thoughts is the result of selection. As the accompaniment of physiological currents playing through the brain, there are constantly offered to consciousness ideas of which the greater number vanish immediately and without being reflected upon. I choose certain of these ideas, in accordance with my theoreti- cal interests or practical needs, and ponder over them and their relation to other ideas. I deliberately make them the subject of my thought, direct my attention to them, and, at the same time, ignore the great rank and file of the actual mental processes, which, consequently, take no place in my thought series. Out of the infinitude of ideas in the stream of consciousness, I choose those about which I wish to think, I emphasize some and neglect others, and thus literally make my experience what I will it shall be. It is, perhaps, so obvious as to scarcely require mention that our external actions are only the outcome of a series of selections. As a rule, when I perform any bodily act, contract this or that group of muscles, some other movement is always physically possible ; and in so far the act performed may be re- garded as chosen. But to say that an act is willed, expresses something more than that an event has taken place which ^ Cf. James, Prijtciples of Psychology, Vol. II, pp. 331 ff. ^ 12 Tke Will. may be regarded as one of several possibilities. Because the results are the same as if willed, because events have oc- curred which from our point of view can be regarded as selections, we have no right to regard them as manifestations of Will, so long as we understand the term in its ordinary- signification. What I mean when I say ' I will' is not only that one out of a number of possibilities w^ill result, but that the selection is the outcome of a conscious activity which I identify with myself. There can be no meaning in the term ' Will ' unless we understand by it, the act of a conscious being.^ But we have still more difficult questions before us. So far, we are on ground which today is scarcely disputed. Selection and consciousness are universally admitted to be involved in the ordinary concept of willing. As soon, how- ever, as we inquire into the degree of consciousness which must attend an act of Will, we find the greatest differences f opinion. Can there be an act of will without a repre- itation of the end for the sake of which the act is per- med ; and does such an act always involve the clear consciousness of the several possibilities or alternatives open at the time ? Many writers, with the ethical signification of acts of will in view, have answered both these questions in the affirmative. Thus Sigwart says the proposition, ' no will without end,' is analytic, just as ' no effect without a cause ' is analytic.^ It must certainly be admitted that all action is for the sake of something ; but this is not the same thing as to say that this 'something' for the sake of which we act, is clearly present to our ordinary consciousness. It ap- pears to me that it is necessary to distinguish sharply be- tween the ordinary unreflective consciousness which accom- ^ It might perhaps be said that not only consciousness, but also a rational consciousness is pre-supposed in a real act of will. As Professor Watson has lately remarked : " Onl}'^ a rational being can have a \N-ill. ' ' ''■Kleine Schriften, II., Der Begriff des Wolletis. The Concept of Will. 13 panics a large part of our daily life, and the more delibera- tive critical consciousness which is evoked when we psychologize, or when some crisis arises which demands closer consideration. In every day life, a conscious end to which we refer each act is as much a fiction as the theory of separate isolated sensations which are consciously compared and related. But analysis proves that the end is always present in potcntia^ in the sense that it has been a real factor in the choice. Subsequent reflection, too, may bring to light the part which it has played. We may perhaps make the matter clearer in another way. On an analysis of my consciousness, I find over and above the transient psychical states, certain more permanent ele- ments. In addition to the passing sensations of sight, sound, etc., there are present the somewhat fixed muscular sensa- tions ; besides the more ephemeral interests and ideals which from time to time becomes satisfied and realized, there are more abiding ends and interests which are more intimately connected with myself. Indeed, it is these which I group together as myself. I am not, however, conscious of them in detail during my ordinary life ; but just because they are comparatively permanent they are neglected. Their influ- ence, however, can at once be percieved as soon as an analysis is made by reflecting on previous actions. The other question, viz., whether in a case of willing there must be present the representation of at least two possible lines of action, is closely allied to this. As a general rule, in performing the routine of every-day life, we scarcely consider or reflect at all ; we act as we have been accustomed to act in like circumstances. In familiar circumstances, we act in accordance with certain practical maxims or receipts, and the one line of action is adopted without the others coming into clear consciousness at all. But inasmuch as the act performed was chosen or adopted, we cannot hesitate to say that it was willed. The most of cases that come up in ordinary life are at once adopted or rejected, because they are immediately 14 The Will perceived to be consistent or inconsistent with the purpose of the life, or of the day. It is only more rarely that it is not evident which one of several actions will be best adapted to our purpose, and that we find ourselves confronted by a prob- lem which cannot be settled in the off-hand way described above. When, however, in consequence of a new combina- tion of circumstances, such a crisis arises, the choice cannot be made without a clear representation of the various com- peting possibilities, nor without more or less prolonged de- liberation upon the results of the various courses of action. It may, perhaps, be advantageous to denominate cases of willing Will in the narrower sense ^ or explicit acts of will, where the choice has been made after a clear conscious- ness of different possible acts, and of their relation to an end. We may then distinguish from this fully con- scious stage. Will in the broader sense ^ or implicit acts of will, where the consciousness of the other possibilities is not so clearly present, but where the act follows the represen- tation of some one line of action as a matter of course. It must be kept in mind, however, that no hard and fast line can be drawn between explicit and implicit acts of will, nor between acts which are implicitly willed, and those which are merely manifestations of unconscious or subconscious tendencies and instincts. We shall endeavor to show in Chapter II, that one species of act passes into another by infinite gradations. Just as on the spectrum we cannot say that at any fixed point red ends, and yellow begins, so, I think, we are unable to fix any divid- ing line in the gradual development of W^ill, as it passes from unconscious and instinctive manifestations to the clear light of deliberative choice. The distinction just made, however, although not absolute, will prove useful in avoiding con- fusions in our subsequent discussions. When we speak of Will, we denote a mental occurrence which has for its object either the production of something which does not yet exist, or the holding fast of something The Concept of Will 15 which we already possess, and which is in danger of being displaced by something else. In both cases, there is a repre- sentation of what is willed ; and if the act of will has been explicit, there is also a representation of other possibilities. In the first case, when the will is directed towards realizing something that does not yet exist, the act follows oftentimes without the competition of other representations. So soon as the act is thought of, it is at once consented to, and adopted. In the other case, where the will is exerted to maintain the present condition of affairs, it is more likely to be explicit. Very often we simply enjoy the present without willing its continuance. It is only when something else comes into competition with the employment or enjoyment of the pres- ent that the will is called into exercise at all. If I am seated at my desk reading or writing, I do not require to constantly exercise my will to remain there. It is only when some other alternative presents itself, e. g.^ that of taking a walk, or of making a visit, that an act of will is necessary to con- tinue my work. If, however, these competing attractions present themselves and I still decide to remain where I am, it is because this has been willed in opposition to the other courses which have presented themselves to me. Further, Will must be directed to something which I be- lieve myself capable of realizing. It must have reference to an act which I can perform, or believe that I can perform. It is not possible that I should will that a rainy day should become fine ; because I can not represent this to myself as lying within my power. The means for the realization of any end which I will must be such as seem to be subject to my control. To will the end implies the willing of the means ; and, further, a belief that these means are such as lie within our reach. It is true that subsequent deliberation may teach us that we were mistaken, that the end can only be obtained through the employment of means which we are unable or unwilling to adopt, but when this becomes obvious, we do not any longer will that the end shall be realized. 1 6 The Will What has just been said enables us to distinguish between ' Desire ' and ' Will '. The former implies only a mere looking towards the end, without any consideration of means. The latter is practical, it sets the machinery agoing to ac- complish the end, and begins with the member of the series which lies nearest to hand. A wish, then, may be di- rected to what lies wholly beyond one's power to re- alize, and it may be wholly unpractical ; i. e.^ take no account whatever of the means. Thus, for example, one may desire wings, or the power to be in two places at the same time. For the same reason, it is quite possible to desire certain ends while the sole means for their realization is not at all desired. For example, I may desire to become learned or rich, and still may not desire to burn the midnight oil, or to practice prudence and economy, as these ends demand. One word further regarding the relation of Desire and Will. We have seen that mere Desire is inoperative and in- effectual in attaining its object. Desire, however, passes into Will when the unpractical ' would that it were ' is re- inforced by the rational ' let it be,' or it ' must not be ' of the self, which speaks with a consciousness of what the act really involves. Desire, we may say, is the expression of the nature of a sensitive being, while Will, in the sense in which we propose to use the term, belongs only to a rational being who has already attained some capacity for ' looking before and after," and who is able to perceive the essential unity of end and means. In conclusion, we may emphasize the fact that will is a mental and not a physical phenomenon. It is not necessar}^, that is, that an act of will shall be manifested in a series of muscular movements. W^e may will without moving a muscle. All the phenomena of will may be present in con- sciousness though there is no perceptible result so far as the external world is concerned. As Professor James some- where sa^^s, ' willing is a relation between the mind and its ideas, not between the mind and the external world.' The The Concept of Will. 17 phenomena which are to form the subject of this study, then, are psychological processes, and it is mainly with an analysis and description of these phenomena that we shall be con- cerned throughout the two following chapters. When this task has been completed, we shall, however, proceed to discuss the relation of mind and body, and shall finally con- sider in what sense it is possible to speak of the freedom of the will. CHAPTER II. THE DEVELOPMENT OF WILL. There is no doubt that it will be more easily possible to analyze an overt and clearly conscious act of will, than to de- termine the nature of process which are largely instinctive, and which go on for the most part below the threshold of con- sciousness. In attempting to analyze the phenomena present in consciousness during an act of volition, we shall accordingly select such an overt act as the subject of our analysis. Be- fore we begin this undertaking, however, it seems advan- tageous to see what light is thrown upon the nature of the explicit will processes by attempting to trace briefly their genesis from earlier and more simple forms. In the first place, w^e remark that the will is an elementary and original process of our conscious life. No matter how far back we may push our investigations, we shall always find the will present as a reaction of the self upon the con- scious content. All attempts to derive wall from something which is generically from it, must necessaril}^ prove fruitless. This assertion scarcely needs proof at the present time, and we may perhaps content ourselves by referring to the futility of Herbart's attempt — which is perhaps now almost uni- versally acknowledged — to derive will from the relation be- tween representations. While emphasizing the uniqueness of the will process, however, modern psychology also points out the organic unity and interrelation of the whole mental life. While the old faculty theory separated sharply between knowl- edge and volition, modern psychologists maintain that in all sensation, all association and comparison, will is also present as a factor. The voluntary control of thoughts is regarded as a process involving will not less than what we usually call vol- untary acts, and which produce an effect in the external world. In short, we may say with Hoffding, " the problem of will is The Development of Will. 19 concerned with the right conception and understanding of attention. " ^ To understand the nature of will, that is, we must begin with will itself. In other words, our develop- ment must be autogenetic^ not heterogenetic.'^ We must give up all attempts to derive will from something different from itself, and confine ourselves to an investigation of how com- plex deliberative acts are evolved from more simple purpose- less acts. There are, says Wundt,^ two questions to be an- swered : (i) " What are the relations of the primitive inner activity of will to the other phenomena of consciousness ? (2) How does the outer activity of will arise from the inner?" We shall so far as possible treat these questions separately, although it will be found, as we proceed, that inner and outer manifestations of will act and react upon each other. We have already asserted, that in every stage of conscious development, there is always some activity manifested by the individual, which, however, becomes explicit onl}- in volition. This is the activity of apperception ; and without this our ex- perience would be a mere series of separate feelings, entirely wanting in any unity. Biit since it is in virtue of the synthetic and dynamic character of consciousness that our experience forms a whole, we may regard apperception as an original ele- ment. iVs we find this activity in lower forms of conscious- ness, however, it is a blind, irrational response to some ob- ject which is immediately pleasant or unpleasant. When strong or absorbing sensations fill consciousness, this activity seems crowded out and to give no sign of its existence. At- tention in such cases seems to be ' a function of the object ' rather than of the subject. But a more or less rapid change of content is a condition both of conscious activity and of con- sciousness itself. When a change takes place, when a new sensation makes its appearance, the activity of the Will is man- 1 Vierteljahrsch. f. wdssensch. Philos., Bd. XIV., Hft. 3, pp. 29. 2 Cf. also Baldwin, Feeling and Will, p. 34-7. 2 Wundt, Griuidzuge der Physiol. Psychologies 3*^'' Aufl. Bd. II, p. 465. 20 The Will. ifested in the mode of its reception. The tvv'o ways in which this involuntary apperception manifests itself are by attraction and repulsion. If the new state is interesting^ i. e.^ if it in- troduces a pleasant change into the existing state of con- sciousness, the attention is directed towards it ; if, for any reason, it is unpleasant, the activity is employed in suppress- ing it so far as possible. This constitutes, as Hoffding re- marks " an elementary choice, and determines the manner in which things shall appear to us. As plants turn to the light, so our perceptive faculties turn to that which excites pleasure and interest, and away from that which excites pain. " ' The selection at this stage, however, is altogether blind and instinctive. It is a mere straining towards what is immedi- ately pleasant, and away from what is immediately painful. A higher stage can only be attained through the development of memory and intellect. This is reached when the ac- tion is guided by the idea of the result, as based on previ- ous experience, and represented to consciousness. There is thus a kind of preparation for the result. The function of the representation thus present to consciousness is to determine to a great extent what shall be perceived. We see and hear mainly what we look for and expect. This preparatory- action of attention, or of the will, is also shown in the ex- periments on reaction time. When attention is directed to the movements to be performed, the reaction time is much less than in the cases where it is directed toward the expected stimulus. At this period of development, we have got beyond the stage of blind instinctive action, and are at the stage of impulse. We have not as yet Will in the narrower sense of a choice between motives, but Will which follows a single representation. There can, under these circumstances, be no voluntary choice in the strict sense of the word ; for there is only a single motive present, and the action follows unhesitatingly in its direction. ^Hoffding, Outlines of Psychology, p. 314. The Develop7nent of Will. 2i / A real choice first arises when different impulses conflict with each other, and we are accordingly compelled to pause and settle the rival claims of possible competing lines of action. It is evident that we do not find such power of deliberation to any extent among the lower animals. In their case, there is no balancing of motives, no weighing of attractions against each other. In the same way, the child's acts are at first all impulsive in character. The object of the whole course of his practical education is to make him think ; i. e.^ to inhibit impulsive action by the idea of consequences ; or, at a later stage of development, by the desire to bring all the acts of the individual life into relation with something which he re- gards as an end in itself. Such a choice requires a degree of mental development, and a power of deliberation and com- parison, which is not found in young children nor in most animals. However important an advance is marked by a de- liberate choice between several competing motives, yet it is evident that such selections have developed gradually from impulse acts. In a given case, it is often difficult to say whether the act has been determined by a single motive, or whether other considerations were also present, but have been, in comparison with the victorious motive, so weak and ineffectual, that they obtained no hold upon consciousness. According to Lotze and some English ethical writers, Will implies a deliberate choice between two or more competing possibilities.' But this is not something radically different from manifestations of which we have been treating at an earlier stage, but is the highest and most complete develop- ment of Will. " The selection of passive, the attention of reactive actions, find their fruition in the fiat of volitional con- sciousness."^ We may describe these phenomena as consti- tuting a complex and intensified form of Will. It is com- ^Microcosmos /., 286.

The one passes by imperceptible stages into the other. -N^¥^¥4heles#^/t isy^a moment of the utmost importance for the development of the Will, when a conflict between differ- ent motives arises, and the original impulse is resisted. Now for the first time the action becomes voluntary. The volun- tary act, however, is not something which suddenly comes upon the scene and supersedes all other modes of action. But throughout life the great majority of our acts are per- formed from instinct or impulse, and a deliberate choice is more rare than is generally imagined. Further, in lower forms of conscious life, there are what we may perhaps call incipient choices. '' Even in instinct, a certain choice takes place in so far as several simultaneous perceptions awaken several different impulses, of which the stronger leads to action. Further, a sense perception can call up a representa- tion, even before the impulse has led to action, which has as a result, an impulse in direct opposition to the first. The action may at once be determined b}' the relative strength of the impulses without any lengthened deliberation of which corresponds to an end. Between this instinctive choice (which has more the nature of passive choice) and the fully self-conscious subordination of individual motives under a maxim or a law, there are infinitely numerous intermediate links. "^-V^The distinctive feature of voluntary or deliberative (' acts of will, is the abstraction from the immediate soliciting '1 power of different impulses, and their evaluation according to ^Kulpe, Die Lehre vom JVilleu, p. 72. ^Schneider, Der menschliche Wille, p. 2S0. The Development of Will. 23 l^the idea of some permanent end. We can now perceive more clearly why voluntary acts should be called an inten- sive form of Will. Although the activity of apperception can be perceived even in instinctive, and still more clearly in impulsive acts, yet it manifests itself most unmistakably in voluntary acts. In turning the attention now to this, now to that possibility, in deliberating and reflecting over the con- sequences, and evaluating the different impulses in relation to an end, the Will manifests itself as the absolute centre of personality. It is this intensified form of Will which compels recognition, and which can not be explained as merely the per- v^ sistence in consciousness of the strongest impression. For '^^ my own part, it seems indisputable that attention is more than 'predominance of an idea in consciousness.' ' y^It is the immediate consciousness of our own activity, as / thus emphasized and intensified in the act of choice, which / constitutes our feeling of Freedom, upon which the sense of \^ responsibility is often supposed to rest. As an empirically given fact, this experience gives no testimony regarding the ultimate question of freedom ; but only asserts that we act without compulsion, that we are forced or pushed by nothing outside ourselves, that the self is the centre from which it has originated. ^ Without that feeling, the moral judgments which we pass upon our own acts would be unmeaning. With that feeling, and because of it, we recognize the action to be our own and accordingly hold ourselves responsible. ^ This is the' basis of our practical freedom, while the more ultimate and metaphysical question can be answered either way without prejudice to our notions of duty or responsi- bility.^ We have now to consider the development of outer acts of 1 Cf. Wundt, Ethik, ist ed., p. 398. '^HofFding, Die Gesetzmdssigkeit der psychische?i Activitat, V. f, w. Phil. XV., pp. 373 ff. 'Sidgwick, The Methods of Ethics, p. 70 ff. 24 The Will Will, as manifested most immediately in changes in the mus- cles of our own body. This development, of course, goes along with, and is supplementary to, the growth of Will as phenomena of consciousness. We have treated of the de- velopment of the latter separately so far merely for the sake of clearness. All bodily movements may be divided into two classes, the purely physiological, and the psychological. The physiologi- cal movements go on mechanically, and are not attended by consciousness, or, at most, it is only the result of the move- ments which enters into consciousness. In psychological movements, on the contrary, a more or less distinct representa- tion of the movement, or of its consequence, precedes its actual occurrence. The former class of movements may be either automatic or reflex. Automatic or spontaneous movements originate within the organism itself, from some change in the condition of the blood, or through some other change in the organism. A reflex, on the other hand, takes place when the nerve current which has been carried to the sensory centre passes out by the motor path without any state of conscious- ness having preceded. Automatic movements are generally random and purposeless, and continue through life, blind, spontaneous discharges of physiological energy. Reflex movements" differ from these in being usually purposive when the stimulus is of medium intensity. One theory of the development of outer acts of w^ill holds that ail acts were at first either automatic or reflex ; and that from these, voluntary movements wxre developed. Bain and Preyer suppose that at first all movements were purely physi- ological, consciousness in the meantime being a mere on- looker and observing the results. In the course of time, however, it learns to direct these movements for its own ends — to inhibit those which have painful results, and to pro- duce those which are pleasant. At first the influence of con- sciousness is small ; but it gradually gains power over the physiological movements, and subordinates them to its con- The Development of Will. 25 trol. If now we separate, as this theory does, consciousness from the original movements, it is difficult to understand how they are again to be combined. Just how the Will should at a certain point take control of movements which previous- ly went on independently of it, we are not told. It is quite in- explainable on this theory, too, how the Will should discover that certain movements are subject to its fiat, and change from a mere onlooker to an actual agent. Moreover, as Wundt says : " What an absurd conclusion to suppose that animals and men have come to the world as purely theoretic beings. After they have experienced many perceptions, and deliberated much, do they suddenly arrive at the idea. How would it be if we should ourselves execute these movements ? Said and done ; and for the future a new and useful power is gained. The only part of this account which has any rela- tion to the facts is the existence of reflex movements. But we neither know that reflexes must always precede voluntary movements, nor that the will ever takes the former into its service. . . We can prove that in many case voluntary movements become mechanical ; for the opposite view, on the contrary, there is scarcely a single trustworthy observation."^ It seems to me that we must refuse to separate outer and inner acts of will as this theory does. There is no doubt that in animals and young children we do find automatic and spon- taneous acts ; but there is no evidence that these ever become voluntary. What seem to us like physiological reflexes are, however, oftentimes psychological reflexes ; that is, at least a large part of the movements even of young children are mani- festations of W^ill. In lower forms of conscious life, every inner act of will manifests itself by means of a movement through which the sense organs are involuntary adjusted to the char- acter of the stimulus. i\lthough we acknowledge the presence of mechanical movements, we shall still have to say that many 1 Wundt, Essays, pp. 292-93 ; Cf., also Martineau, A Study of Religion, Vol. II, pp. 202-203. 26 The Will. phenomena which appear to be purely physiological are in fact psychological. The outer movement is only the other side, or the immediate result, of the apperception of the idea of the movement. " Outer acts of Will are only a product of Apperception which has arisen under complex conditions.^ As we shall see more clearly in a later chapter, the apperceiving process of the idea is the inner act of Will upon which the outer manifestation at once follows. We are indeed able in adult life to form the representation of a movement without it actually taking place ; but this is because we inhibit the movement by thinking at the same time of its not taking place. There is good reason to suppose that Apperception and outer acts were originally inseparable, and that their separation rests upon a later development of consciousness.^ This kind of action, which has been named ideo-v:\o\.ox^ is the type of all movement, and depends upon the law that every idea of the mind tends to realize itself in movement unless held in check by the idea of other movements. There seems, then, strong reasons for refusing to separate inner acts of will and outer movements. Wundt argues that we cannot point to a single case where reflex acts have become voluntary, while experience constantly shows us that the opposite is the case. If the will were able to assert its mastery over a sure working reflex mechanism, all the more complicated movements would be acquired at a single stroke. As a matter of fact, however, we learn such movements as walking, dancing, piano-playing, by long practice. It is only after they have been performed voluntarily for a longer or shorter time that they are handed over to a mechanism.' The order of development of outer acts of will, then, is from psychological reflexes or impulsive acts to voluntary, and MVundt, Grundzuge des physio! . Psychologic . Bd. II. p. 470. ^ Wundt, Grundzfige des physiol. Psychologies Bd. II, p. 471. Compare also James, Psycholog}-. Vol. II, pp. 526-27. 'Wundt, Essays, p. 294. The Development of Will. 27 again from voluntary movements to mechanical or physio- logical reflexes. The impulsive or instinctive acts are first rationalized ; i. e.^ brought into harmony with some universal end, as preservation of self, or species. Indeed, many of these impulses are themselves rational from the beginning. It is not the task of reason to erradicate these natural im- pulses but to direct and control them. When habits have become formed, consciousness, having done its work, ceases to attend these processes, and they go on themselves in a purely mechanical way. We sometimes are able in later life to catch a glimpse of these old untamed impulses when a temptation seizes us at times to do some utterly senseless act ; and sometimes, too, it takes all our will power to inhibit and control such impulses. Of course, this account does not necessarily imply that all actions go through this transformation. Many movements remain throughout life at the impulsive stage. They may even continue to be subjects for deliberation, or at least con- tinue to be attended by some degree of consciousness. Such, it seems to me, are many of our most common impulses, as for example, that for food, or for revenge. Again, many of the acts which were once performed voluntarily may not yet have entirely passed over to the mechanical stage, but may still be attended by more or less distinct consciousness. The presence of actions of this kind seem, however, rather to con- firm our theory than to be opposed to it. For such move- ments represent intermediate stages of the process, they are acts which are on the way, one may say, to become reflex. CHAPTER HI. AN ANALYSIS OF WILLING. Will does not exist as an isolated element of our conscious- ness which is given to us directly through introspection, but it is rather a concept which is formed through analysis of the highly complex facts which are given to inner perception/ There are, no doubt, certain phenomena of consciousness which are usually known as volitio7is^ because in them will or activ- ity of consciousness seems to be the most distinctive feature. Yet neither volitions, nor cognitions, nor feelings, form by themselves actually existing states of mind. As Mr. Ward says : " Instead of three coordinate species, cognition, emotion, conation, we have three distinct and irreducible facts, atten- tion, feeling, and object or presentation constituting one con- crete state of mind or psychosis, " - Our problem will then be to analyze and describe the em- pirically given content of that psychical phenomenon which we name volition. Although much attention has been be- stowed upon this subject, and much keen introspection has been employed, yet psychologists by no means agree in their descriptions of the facts. However, upon one point all are agreed. When a voluntary act of the clearly conscious sort is performed, there is always present to consciousness a rep- resentation or prefiguring of the result. If a movement is to be willed, there is first a representation in consciousnesss of how the movement feels or looks. It is of course necessary, in order that these conditions may be fulfilled, that this move- ment should have been previously performed. And so vol- ^ Cf. Wundt, " Zur Lehre von den Gemiithsbeweguiigen, ' ' Phil. Studien, VL, p. 382 ff. 2 James Ward, Mind, " Ps^xhological Principles," No. 45. See also the same author's article," Psjxholog}' " in the Ency. Brit. A7t Analysis of Willing. 29 utitary movements presuppose and are developed from invol- untary. We find, then, that our ability to perform any ex- ternal act at first depends upon our ability accurately to pic- ture to ourselves how the necessar}^ movement feels, i. e.^ to reproduce the sensations which have previously arisen from muscle and joint during its performance. These sensations have been called the kinaesthetic impressions ; and they are of the greatest importance in learning any new movement. But after an act has been performed a number of times, the kinaesthetic impressions are no longer called up, but more remote sensations, often of sight or even of the consequences of them are all that are necessary for the successful accom- plishment of the required movement. As Professor James has pointed out in his admirable chapter on the Will, ^ sensations which are of no practical importance tend to pass out of con- sciousness. When in learning to row, for example, I have by some chance taken a stroke in good form, my attempt to re- peat it consists in striving to reproduce they^^/ of that stroke, the kinaesthetic impression of that movement. Later, however, when I have by practice become more expert in the art, I am guided by the more remote sensations derived from sight or so\md. But besides these representations of the more or less remote results of the action, concerning the presence of which psy- chologists are agreed, is there aught else present ? Miinster- berg agrees with the ordinary description of volition so far as to admit that there is also present a feeling of inner activity.^ How he proposes to explain this activity-feeling, we shall learn in a short time. Let us now, however, turn to the same author's statement of the problem before us : " Modern Psychology names the last analysable elements into which the content of consciousness can be divided sensations " (Empfindungeny The will, then, so far as we are concerned ^ James, The Principles of Psychology, Vol. II., pp. 486-594. ^ Miinsterberg, Die Willenshandlung , pp. 60-63. 30 The Will. with it, is only a complex of sensations. " The group of sensations which we name will, may by its complexity and constancy be distinguished from other sensations, yet the ele- ments which result from the analysis are coodinate with the elements of ideas. Our problem then is to determine what intensity, quality, and feeling tone belong to this group of sensations w^hich we call Will." ^ This statement seems to me to beg the question in a very obvious fashion in favor of the position ]\Iiinsterberg is con- cerned to maintain. The statement that sensations are the last elements into which our conscious phenomena can be an- alysed, is true only of those elements which enter into com- pounds, or form parts of an objective representation.^ The Will, the primary activity of the self, cannot be known as an idea like other ideas, as Berkeley long ago maintained. And to seek for a definite state of consciousness with a fixed indi- viduality of its own is to rest the problem, it seems to me, upon a fundamental misapprehension of the nature of con- scious states. Miinsterberg seems to demand that there should be found some peculiar individual state of conscious- ness which we call Will, and failing to find this he seeks no further. Wundt, in the article above referred to, excellently describes this tendency to substantialize the content of con- sciousness. " For the adherents of this theory the mind is a bundle of presentations {Vorstelhcfigefi.) Like the perma- nent objects of the outer world to which they refer, the pre- sentations are supposed to modify each other in our conscious- ness ; but, at the same time, to constitute for us only objects of passive observation. We can add nothing to them, nor take anything from them. Our own activity is only a pre- sentation, which, like all others, is subject only to our obser- vation. What is not given to us in this way does not exist. ^Miinsterberg, Die Willenshandliing , p. 62. ' Cf. Wundt, " Zur Lehre von den Gemiithsbewegungen," Phil. Studien. VI, p. 384. An Analysis of Willing. 31 Our will, therefore, must be a presentation which is analy- sable into definite sensations that can be traced back to some physiological stimulus." ^ It is clear that this strictly intellectual account of con- sciousness is entirely mythological. The true view is rather that there are three 'aspects' in every conscious state, all of which are essential in making it what it is. These aides which belong to every conscious process are : (i) knowledge of its signification ; (2) its ' emotive ' or ' affective ' aspect ; the way, that is, in which it affects me ; (3) the manner in which I relate myself to it. This latter element, it appears to me, is known as directly as either of the others. We name the state according to its signification for knowledge, and fall into the mistake of supposing that this aspect com- pletely exhausts its content. Dr. Miinsterberg contents him- self with analyzing the content of consciousness into so many ' phenomena ' each having a definite content and remaining what it is, altogether independently of its relation to the subject. He materializes the phenomena of consciousness and makes the self a mere onlooker. Then, since it is found there is no such phenomena in the case of Will to analyze and name, the conclusion is reached that the latter can be at the bottom only 'a complex of sensations.' Not sensations nor reproduction of sensations as such constitute the phe- nomena of Will, but sensations and their reproductions which stand in definite relations to one another and to the spiritual essence.'^ A mental state is not something whose signification is known out of all relation to the self ; but the attitude of the self to the sensation is an element in its nature which must not by any means be neglected. The content of the mental state on its knowing side has a more stable constitution than that of the feeling and willing aspects. ^Wundt, "Zur Lehre von den Gemiithsbewegungen" P;^//. Stud., VI, p. 384-85. ^Lipps, Vier.f. w. Phil., Bd. XIII, p. 177. 32 The Will The former element being of 7nore practical significaiice is the only one connoted by the name given to it. This ele- ment also enters into more complex states of knowledge, while our relation to it which the name does not describe, and which cannot be named, does not form an element of higher compounds and so is often overlooked/ To return to Dr. Miinsterberg's analysis of Will. The es- sence of the volitional he finds as we have seen in the feeling of inner activity ; but in accordance with his work- ing presuppositions this activity can be nothing more than certain substantive states of mind. Dr. Miinsterberg first examines the case where the will is confined to the control of attention and the direction of the processes of thought. In all cases of Voluntary change of content, these preceded the clear consciousness of any representation another state which, in regard its content, already contained the former. In every case of involuntary change there was no element preceded the new state which contained it. When I arrive at a through b by involuntary association, these states may have certain characteristics in common, biit b does not con- tain a. When, on the contrary, I think of a and seek it in my memory, what I perceive is not ;/ nevertheless it is some- thing which agrees with it in content. So long as a is not found, I perceive only an x ; but this x exists in a series of relations through which it can be known only as a and nothing else." Let us now examine this somewhat detailed statement a little more closely, using the concrete example which Miinsterberg himself employs, that of trying to recall a name. " I try to think of a word, I remember the place ^Since the above was wTitten this point has been much more clearly and fully worked out by Professor Andrew Seth. ' E\'identh- if phenomena or objects of Consciousness are alone to be accepted as facts,' says Professor Seth, ' then all real acti^dty on the part of the subject is necessarily elim- inated.' Man's Place in the Cosmos, pp. 94, ff. "^ Die Willenshandlung , pp. 67, if. An Analysis of Willing. 33 where I read it, I know exactly its meaning, but it is not present ; finally it comes to me. Now that word is fully given as to its content in the previous state of conscious- ness." ^ For my own part, I fail to understand what mean- ing is here to be given to the phrase "as to its content." The name is not contained in the previous state, but is only connected with this by many lines of association. Nor is it true that only the name can result and nothing besides. In some cases, all our efforts to remember may prove fruitless. The X still remains an x and no definite value can be assigned to it. Or the wrong word may be recalled and mis- taken for the one of which we are in search. It does not seem that this criterion serves adequately to distinguish voluntary thought processes from the results of involuntary association. In the latter case, as in the former, any state of consciousness must have been preceded by another or others which were related to it in some way. But it is an un- disputed fact, that in the one case there is ah x^ a state whose content is not determinate, present to consciousness. This is of course not a representation with any definite con- tent, (the X in so far as it is an x has no content), but it is the mere form of voluntary iviiling. If some thought or word is sought for, the x is the consciousness of this striving as directed towards some goal. In a chain of reasoning, the goal to be arrived at is indeed generally present, and de- termines the steps of the thought process. The representa- tion of the end, however, does not contain the conclusion ; for the latter may be directly opposed to it. It does not seem to me that this analysis which Miinster- berg has given is convincing, or the immediate evidence of our consciousness can be so lightly set aside. The belief that we are agents, however, Miinsterberg accounts for in two ways. First, when a train of thinking is going on smoothly, we have no especial consciousness of the activity ^ Miinsterberg, Die Wille7ishandlung, p. 67. 34 The Will, of the will. Reflection, nevertheless persuades us that we have been active by the use of the most important criterion, that the representation of the completed act in such cases was always present to consciousness in the previous moment. For this reason, then, we conclude that we have been agents. But, as a matter of fact, "we can only will a so long as it re- mains in us ; and so long as it remains, we cannot, as em- pirical personalities, set it aside. Our Will in this case means only that a has remained in our consciousness, that the content of every moment was already contained in the foregoing state." ^ Furthermore, if we are conscious of our own activity dur- ing the action itself as we are sometimes in thinking and must always be in bodily actions, this feeling can be analyzed into feelings of strain in the organs or a tightening of the skin of the head. Now it is doubtless true that inner mani- festations of Will are invariably accompanied by such bodily feelings. If we tr}^ to discover the phenomena of volition, these are the only explicit ' states of consciousness ' which can be named and described. Yet these bodily sensations are not themselves the feeling of activity, nor do they constitute the essence of Will. They may often fuse with this latter feeling or be mistaken for it, but yet it is possible by intro- spection to distinguish the activity feeling from such strain sensations. These bodily sensations which often remain after the feeling of activity has disappeared ; and, moreover, after they have vanished, they can be recalled. The feeling of inner activity, on the other hand, is a something altogether sui ge7teris^ and expresses certain relations of the ego and its content, as opposed to the passive side of representations, which we objectify. The feeling of activity is that which constitutes chiefly our immediate experience of the self, with- out which bodily sensations would not be experiences at all. " How can one," asks Lipps, " seek in anything which be- ^ Miinsterberg, Die Willenshandlung , p. 70. An Ajialysis of Willhig. 35 longs to the world, that feeling of effort by means of which what is and happens both in the external world, and in the world of the body, become for our consciousness an object of doing or suffering." ^ In the case of involuntary changes of content, the new ideas appear as something foreign to our- selves, something belonging to the Non-ego. In the case of voluntary alterations of conscious content, through the agency of the feeling of activity, they are known as mine ; i. e.^ as belong to me in a peculiar sense. How then can this feeling, in virtue of which the world is first made ours^ or is opposed to us, be attributed to any element of the world itself? In thus defining the feeling as that which expresses the relation of opposition between the self and the world of objective phenomena, we must remember that this definition is not identical with the fact given in immediate perception. The sigitification of the feeling is discovered only by reflec- tion ; in actual experience itself, there is no knowledge or no separation of what is given as inner and outer." It does seem to me, however, that we do know of feelings and volitions immediately, in the same way as cognitions are known, and not merely through results. When we voluntarily attend to any object, our attention is withdrawn from other objects. Instead of being diffused and occupied equally with several representations, it is focused upon a single point. This forms, for the time, the centre around which our thoughts cluster ; and the point into agreement with which they must be brought. But this feeling which attends the narrowing of consciousness is not the reason why we feel ourselves active, or, in other words, the feeling of activity is not merely the cognizance of the contraction of consciousness ; for in cases where some striking event or object fills consciousness, we ' Lipps, " Bemerkungen Zur Theorie d. Gefiihl," Vier. f. w. Ph. Bd. XIII, p. 190. "^ Cf. Wundt, "Zur Lehre von den Gemiithsbewegungen," Phil. Sttid,, VI. 36 The Will. have the contraction without the activity experience. The mere predominance or permanence in consciousness of any idea is not, then, sufficient to explain this feeling. As Mr. Ward says : " It is ob\'iously impossible that what is a con- stituent in every psychical event, can be explicable in terms of psychical events. And the demand for such an explana- tion leads logically to a tacit denial of any heterogeneity in mind at all."^ Nevertheless, ]\Ir. Ward seems to hold that attention can never be known per se. It is rather a neces- sary inference, a sine qua 71011 of explanation than a fact which can be knowm immediately. He writes : " It is neither a pre- sentation nor a relation among presentations, nor, strictly speaking, an unanalysable element in the presentations them- selves. An unanalysable element in every state of mind, I admit, but one which even in reflective consciousness is never directly presented. I see no very serious objection to saying that all we know about it is an intellectual construction, or even an inference, provided that it be allowed that every proposition in psychology is completely eviscerated if this inference is neglected." " Hoffding also argues against an immediate cognition of the activity of the self. Such a state, he contends, if immediately perceived, must be simple and unconnected like our sense im- pressions. It must appear with a definite quality w^hich is as little to be mistaken as the quality of the sensation of color. Now, activity and passivity are only relative notions which are indicated by a greater or less concentration of conscious- ness. To what ofrade of concentration does this feeling: cor- respond. There can be no such characteristic mark or crite- rion of W^ill; for if there were, there could be no mistakes in practical life. But, as a matter of fact w^here a volition can- not at once be put into effect, we can never be certain that ^ James Ward, Mind, No. 45, p. 66. * James Ward, Mind, No. 48, p. 570. Cf. Also the article, " Psychology,' in the Enc\'. Brit. An A^ialysis of Willing. 37 our resolution has been made, that it will not be ' sicklied o'er with the pale cast of thought. ' Our only criterion is the experience of our own character. ^ These arguments seem to me to rest upon the same implicit demand which has been so often referred to in this chapter; the demand for some definite conditions of consciousness which can be classified as phenomena of will, each having a fixed con- tent which is as definite as a color tone. But our argument has gone to show that just because the Will is indispensable to all mental life, it is difficult to discover any special mental state to which we can point and say, ' lo, it is here.' As we do not base our notion of the self upon any particular feeling or representation, neither can we do so in the case of the Will. Further, in reply to Hoffding's objection, we may say that there is nothing to prevent a decision which has once been made from coming up again for consideration. Bvery decision regarding the future is made only hypothetically ; and another day may bring additional light, or a different frame of mind. But Hoffding urges, further, that even when we appear to be most clearly conscious of a resolution, when it is so explicit that we say ' I will,' the real deciding point does not lie here, but the whole matter was really determined much earlier. The explicit ' fiat ' is often only the official expression of that which has been already decided. It is no doubt true that in such cases the decision consists in referring the act under consideration to some end previ- ously adopted, as a permanent principle of action. In this way, many of our customary acts are decided at once with reference to some such end. But if the act of volition is ex- plicit, it marks the termination of a conflict between that end and some other lines of conduct. A mere subsumption would take place quietly, almost unconsciously. The ' I will ' do this or that, shows that something else has entered into competition with it, that the end has tottered on its throne ; or that up to Hoffding, Outlines of Psychology, (Eng. trans.) pp. 340 ff. 38 The Will; this time the minor premise of the practical syllogism, ' this is a case of that kind ' has been wanting/ We now return to our analysis of Will, and shall consider two cases representing respectively an explicit act of inner volition, and an external act of Will. In what does the essence of an act of inner volition consist ? Suppose that we take the case where there are two alternatives offering them- selves to us, and suppose that after deliberation, A is chosen although B has stronger immediate attracting power. How shall we describe the act of will by means of which A is chosen ? If we leave out of account the various processes of sensa- tional strains which accompany the volition, as well as the representation of the various consequences of the alternatives under consideration, we must say that the essential moment of will consists in fixing the one alternative before us by means of the selective attention. Putting our analysis in terms of content, we may say that the volition is the imme- diate feeling of activity, plus the steadiness and predomi- nance in consciousness of A. When we can attend to A solely and continuously, then, as Professor James says, it is willed. " We have thus reached the heart of our inquiry when we ask by what process it is that the thought of any- thing comes to prevail stably in the mind. . . . We see that attention with effort is all that any case of volition implies. The essential achievement of the zvill in shoj't^ when it is most voluntary^ is to attend to a difficult object^ a?td hold it fast before the 7}iindy - Notwithstanding this excellent statement, however, the tendency of James's analysis is to make too little of the conscious activity involved in volun- tary experience, and to describe the volition purely from the side of content. When this is done, the alternative chosen seems to fill consciousness because of its superior attractive- ^h.TisX.oW'^.Nicomeachean Ethics., Bk. VII. "^Principles of Psychology, Vol. II, p. 561. An A?talysis of Willing. 39 ness. In other words, the subject appears to be passive rather than active. This is probably the danger in putting the description of an act of will solely in terms of attention. Or, perhaps, we should say that it ought to be remembered that the attention is not merely the power of raising certain mental processes to a greater degree of intensity ; but is also an intellectual function which has the power of relating and incorporating ideas with the rest of our experience. It is not entirely true, then, it seems to me, to describe a case of de- liberate willing as a mere act of holding a representation in consciousness. The idea which has been chosen has been adopted, not merely on account of its greater intensity as a process in consciousness, but because of its significance and its coherence with the permanent ends of our life. This in- tellectual function of attention or will is very clearly brought out by Professor Baldwin in the following quotation : " The attention moves through the series of elements, grasping, re- lating, retaining, selecting, and when the integration it effects swells and fills consciousness, that is the ' fiat.' Just as soon as the elements of the end cease to act as partial influences caus- ing the movements of attention by their vividness, and the at- tention gets its hold upon the integrated content, the fiat goes forth." ^ There is no new element added to the volition as a psycho- logical fact when the act becomes an external one, and effects some change in the world of objects. The arguments of James ^ and Miinsterberg ^ seem quite convincing against the existence of any special innervation feelings ; and even Wundt has modified his position on this question. * It is not neces- ary that we should first have the volition as an internal fact, and then add something to it to get external volition. The ^Baldwin, Feelhigs and Will, p. 355. ''■Principles of Psychology, Vol. II,, pp. 494 ff. ^ Die Willenshandlung , pp. 75 ff. * Grundziige de7' Physiol. Psychologie, 3**' Aufl., Bd. I, pp. 400 ff. 40 The Will. truth rather seems to be that the division between internal and external volition is itself an artificial one. Every state of consciousness has its physical side. A volition is at once a psychological fact, and a moving force in the external world. As James says : " We do not first have a sensation or a thought, and then have to add something to it to get a movement. Movement is the natural immediate effect of feeling, irrespective of what the quality of the feeling may be. It is so in reflex action, it is so in emotional expression, it is so in voluntary life. " ^ No analysis of deliberate acts of will, however, is complete w^hich does not take account of the subordination of particu- lar acts under a permanent end. In order to complete the analysis of such an act of volition we pass on to a brief treat- ment of this subject. In impulsive actions, there is no reference to anything be- yond the act itself. There is present in such cases a loss of equilibrum in the psychical condition, and a more or less dis- tinct desire of something to be realized ; but there is no con- ception of an end under which the action is to be brought, or to which it is referred. End and means in this case coincide. Impulsive actions may be defined as movements which follow^ immediately the perception of the inciting object. There is nothing beyond the immediate act present to consciousness, and so there can be no thought of an end. The actions of children and of animals are almost altogether of this sort. Mankind, however, does not remain at this stage, but in virtue of his reason soon rises above it. " Human Will is not de- termined by that only which excites, that is, immediately affects the senses ; but we possess the power to overcome the impressions made on the faculty of our sensuous desires by representing to ourselves what in a more distant way may be useful or hurtful. These considerations of what is desirable ^Principles of Psychology, Vol. II., p. 527. A7t Analysis of Willing. 41 with regard to our whole state, that is of what is good and useful, are based entirely on reason."^ It is man's ability to hold before himself possibilities as yet unattained, which be- come for him laws, that makes him capable of reaching a higher intellectual and moral plane than the animals. Besides the impulse to preservation of life and offspring which man shares with the lower animals, and which necessi- tates some union for the sake of protection, there are other irresolvable tendencies which we regard as peculiarly human. The first of these is the feeling of sympathy in the pleasure or pains of another, in virtue of which we are able to identify ourselves with him, and for the time to make his ends ours. Thus we speak of a man who is incapable of sympathy as inhuman. The second of these peculiarly human impulses may be called the intellectual motive. The animal intellect is the servant of desires and appetites, and is only called into action through their demands. At first, indeed, in the his- tory both of the individual and the race, it is practical needs which arouse intellectual activity. The end at this stage is set by some practical necessity, and the intellect is moved to seek means for relief. But while these practical needs must always remain ends for us, man as an intellectual being finds satisfac- tion in the exercise of thought for its own sake ; and without any practical end in view, reflects upon phenomena and their relations, purely for the pleasure which such activity brings. The result of this reflection is speech. It has been well remarked that animals do not speak because they have noth- ing to say. They never exercise their faculties for the sake of discovering truth, but always with some practical end in view. Man, on the other hand, in virtue of this intellectual impulse is able to make truth his goal, and to discover facts regarding phenomena and their relations which he expresses in language. But if these were the only additional equipment of a man^ Kant Kr. d. r. V., (Miiller's Trans.), p. 688. 42 The Will. they would involve him in hopeless realism with himself. Sympathy and self love, egoism and altruism come into irreconcilable conflict. In the region of theoretical reason, too, oppositions and antinomies arise. In overcoming these discords and contradictions, man realizes the highest goal of his intellectual and moral nature. It is the last class of human impulses which leads us to seek a harmony, a union in the play of different motives, and agreement and order in the phenomena of our intellectual life. Just as in the intel- lectual sphere the highest pleasure is experienced when " unity is introduced into the manifold," so the center of our soul life which is disturbed and pained by the clash of disharmonious motives conceives the idea of a union in a supreme end which will include in itself and harmonize all the ends of life. Reason, as Kant tells us, is a " function of unity." In its speculative employment, it leads us to postu- late an absolute synthesis, and furnishes the conceptions of truth and beauty, the ideals of Science and of Art. When it is practical, it seeks to subordinate conflicting desires to a higher principle. It seeks beside the many things which we name goods, one Supreme Good in which these other goods are taken up, and through comparison with which their rela- tive values are assigned. This impulse after unity introduces order and harmony into the soul, and so plays the same part as Justice in Plato's Republic. Just how this highest good, this unconditional end, is to be defined is a question to which different ages and peoples have given very different answers. Why this is so w^e shall see later. At present, we can say that man's potentiality of advancement depends upon the presence of these ends. To the lower animals, even if they had the power of set- ting before themselves ends to be realized, the pleasure or pain of another, or the intellectual ideals of humanity, would not appeal. These are ends to us because we will them, and we will them because in virtue of our humanity they are in- teresting to us. These intellectual and moral impulses are An Analysis of Willing. 43 not, however, so strong and irresistible as the animal appetites. These latter have to provide for the production and maintenance of life itself, and consequently are more imperative in their demands. The distinctly human im- pulses, on the other hand, are rather gentle forces which work imperceptibly in the individual and the race, and the ends which they prescribe are not so irresistible as to compel man to embrace them. Often the more urgent demands of life crowd them out of sight, and they fail to make their in- fluence felt. This may happen in the moral sphere through either the altruistic or the egoistic impulses (more frequently the latter) assuming such proportions that they dominate the whole life ; e. g.^2. man may be so consistently selfish that no conflict is felt. But where this lack of harmony does exist, it may lead to a desire to overcome the disunion, or the in- dividual may be swayed in turn by selfish and unselfish motives. When the latter is the case, his life is made up of incongruous parts, and does not form a consistent whole. It is now necessary to consider the part which environment plays in prescribing ends for the individual. We have hitherto spoken as if the ends of life were wholly prescribed by peculiarly human influences. While it is no doubt true that the form is wholly or in part prescribed by natural impulse, yet the content of the end is largely determined by external influence. The intellectual development of the individual, the moral status of the community to which he belongs, or of the persons with whom he is most intimately associated, pre- scribe to a large extent the ideals which appeal to him. It is a familar truth that example is more forcible than precept, and that a man may be known by the company he keeps. Every society has certain norms of conduct which it prescribes for its members, certain standards to which it expects them to conform. These are adopted by the individual in a blind unconscious way, and become part of himself. He breathes them in with the air, and, since they are the common prop- erty of society, they form a bond of union between the indi- 44 The Will vidual members. The common stock of hopes and fears, wants and pleasures, constitute the solidarity of mankind. These ideals are as much a part of the inheritance of the individual as his language. Yet these norms can not in every circumstance of life lay down a complete code of conduct for the individual. And again, these ends may conflict with his own natural impulses or appetites. In the first instance, the individual will strive to bring the act under some general principle by which he has been guided in the past, and in doing so, will give it a concrete content and make it a reality to himself. Or, if the end prescribed by society runs counter to his own inclina- tions, a conflict will ensue which may result either in his re- jecting the end, or in affirming it for himself. In the latter case, he has by affirming it made it his own, and identified himself with it. If a boy, e. g,^ has been taught the rightness of truth speaking, he may assent to the principle without really adopt- ing it for himself. It is to him abstract and unreal, and with- out content. But after having affirmed this principle in con- crete cases, after, it may be, having brought all kinds of de- ception under the same category as lying, this end gains for him a wealth of meaning, and a reality which it did not before possess. After having acted in accordance with this princi- ple until it becomes a custom, it may become again less con- crete. To speak with Hegel, we might say that the end was at first abstract and universal, then became concrete and en- riched with details, and that finally these concrete cases were taken up into the universal. But it is no longer the blank, abstract universal vrith which we started, but a concrete universal which includes within itself the meanings of the sec- ond stage. But it must be remembered the end is not strictly speak- ing something distinct from the individual. In truth, the end to be an end at all must be something with which the indi- vidual has identified himself. It must form part of the per- manent centre which constitutes for the time being himself. An Analysis of Willing. 45 The act by which he strives to realize that end is the expres- sion of his own character. Kven when there are two or more competing lines of conduct presented to us, we can not speak of any of them as ends except in an anticipatory way. At first they are all representations external to the self ; when afterwards one is chosen, it is taken up into the self, and the rejected possibilities are to us henceforth as nothing. We have been all along attempting to show the close con- nection between speculative and practical Reason. In the former not less than in the latter, we have one end which we strive to realize. What we keep before ourselves in thinking, as the goal towards which our efforts are di- rected, is the completion of the process itself ; the under- standing and clear perception of a system of relations which -we think of as already existing in reality, whatever meaning we attach to reality. In willing, the end sought for is some new condition or event which we wish to call into being. Yet the two processes are not essentially different, and cannot be divorced from each other. While Will cannot be de- rived from thinking, or thought from Will, yet each process involves the other. At least all cases of conscious volition involve thought, and are in fact only an application of the practical syllogism. In other words, " every action implies a sense of a general principle, and the applying of that prin- ciple to a particular case, or it implies desire for some end coupled with perception of the means necessary for attaining the end. " ^ And we have already had occasion more than once to refer to the fact that thought involves Will, and is really a series of selections. . IT 1 Sir A. Grant, The Ethics of Aristotle, Vol. I., p. 266. CHAPTER IV. THE PSYCHO-PHYSICAL PROBLEM. i\lthough " volition is a psychic or moral event pure and sim- ple, and is absolutely completed when the stable state of the idea is there," ^ yet it seems to produce effects in the external world. The most immediate result of such an outer act of will is a movement, due to some modification of muscular tissue. It is not, however, the fact that there are movements which seems to demand explanation, but that these movements should correspond to, and seem to obey, states of consciousness. Though there remain many gaps for physical science to fill in before we can understand exactly what takes place in the dif- ferent stages of the volitional process, yet we can not doubt that as a physiological event it can be accounted for mechanically. Nevertheless the direction of nerve currents, the fact that the organism is directed and controlled according to the idea of certain ends, seems to indicate a connection between the two series — indeed at first sight it points to the dependence of physical phenomena upon psychical. On the other hand, there are certain facts which point to the dependence of mental states upon physiological processes. In the first place, it is to be noted that the psychic phenomena with which psy- chology busies itself, do not form a continuous series. There are gaps which it seems impossible to fill up completely from the mental side. Consciousness appears in the first place to derive all its original material in the form of sensations through the media of the brain and nervous system. These organs seem to hand over to consciousness ' the raw material ' of sensation, and to be constantly introducing foreign matter into the thought series. It is undeniable at the same time that the nature of psychic states, and even their existence, is con- James, Principles of Psychology , VoL II., p. 560. The Relation of Mind and Body. 47 ditioned equally by the character of consciousness itself ; but in sensation we always seem forced to refer for an explana- tion to something further, something outside of ourselves. And not only is this the case in sensation, but also in explain- ing the connections of the psychical content, we are often obliged to put our account in terms of brain and nerve physi- ology. Professor Wundt remarks : " Since the connection of representations in our consciousness refers everywhere to con- ditions which lie outside of consciousness, and therefore can not be given to us in the form of mental phenomena, Psy- chology will be not seldom under the necessity of having re- source to physiological investigation. In cases where the causal connection of inner experiences seems to be inter- rupted, it is necessary to give an account of those physical phenomena which run parallel to them. With this object in view, the Psychology of sensation calls the Physiology of the sense organs to its assistance. And, in the same way, the explanation of the changes of conscious states can not refrain from referring to the Psychology of the brain." ^ This apparent reciprocal dependence of mind and brain, forces upon us the question regarding their exact relation. This is a most perplexing problem and one for which we can- not perhaps expect to find a complete solution. It may not be in vain, however, to state the problem clearly, and endeavor to come face to face with the difficulties involved in it. There are at least two questions which we can keep separate from each other. The first is the problem which science, adopt- ing as it does the common sense standpoint, must raise in re- gard to the relation it is warranted in predicating between the phenomena with which Physiology and Psychology deal. It is, one may say, a methodological question regarding the most profitable way in which these sciences shall carry on their investigations. The other question is metaphysical, and is concerned with the ultimate nature of body and Wundt, Essays, p. 116. 48 The Will mind. It has to attempt to discover a tenable theory of the ultimate underlying unity in virtue of which these different classes of phenomena can both belong to the same world. We have every reason to suppose that all states of consciousness are accompanied by corresponding nervous states. We know that any considerable change in the physi- cal organism, particularly in the brain, is attended by dis- turbances in the mental sphere. We also became convinced, in analysing the phenomena of Will, that when any representa- tion fills consciousness a muscular movement at once follows. Further, we may point to the fact of the quantitative relation between the external stimulus and the resulting sensation which has been formulated by Weber's law. All these facts of correspondence seem to indicate that the two series are not ultimately separated, but belong in some way to the same world. ^ The question which will first concern us is that regarding the relation which, from the scientific standpoint, we are war- ranted in predicating between mental and physical phenome- na. There are at least three possible attitudes toward this question. The first of these conceives it to be the business of science to limit itself to some particular field, and to attempt to find invariable connections and sequences between the phe- nomena in that field. The science of Psychology deals with " the uniformities of succession, the laws whether ultimate or derivative, according to which one mental state succeeds another. ". - The subject matter of neurology is the nervous system and its functions and changes. There must then be no confusion of the respective spheres of these two sciences. " Functions of the brain may correspond to, or may hold some other relation to mind ; yet mind and brain are not the same, the study of the brain is not the study of the mind, physiology of the nervous system is not psychology. ^ ^ An excellent account of the parallels and analogies of the two series is given by HoflFding, Outlines of Psychology, (^Eng. trans.) Chap. II. ^'Mill, System of Logic, Book VI., Chap. IV. ^ 'Scripture, " The Problem of Psychology," Mind, No. 63. The Relation of Mind and Body. 49 It is no doubt often advantageous and desirable where one series can not be completed, where some of its links are wanting, to give the corresponding links of the parallel series. However, where this done, it can never be regarded as a final explanation. This can only be done — to quote again from Dr. Scripture's article referred to above — " with the recognition that they are but te7nporary substitutes.'^'^ While thus limit- ing Physiology and Psychology to a particular sphere, the question is still left open as to the ultimate relation of the phenomena with which they deal. " It is not to be under- stood that by this limitation of the problem of psychology any opinion whatever is expressed regarding the relation be- tween mental phenomena and bodily phenomena. Let the relation be what it will, the question must be kept out of psychology." ^ One cannot but approve heartily of such a clear statement of the subject-matter of the two sciences. It cannot be doubted either, that a protest is called for against the tendency discernible in the writings of some psycholo- gists, to explain mental phenomena by furnishing a more or less mythical account of what takes place in the brain. There is, however, another set of facts which is not in- cluded in either of these sciences, which we may call the fact of the corresponde7ice of the physiological and the mental series. If we say that it is the province of physiological-psy- chology to investigate the correspondences and connections of the two series, the question inevitably recurs concerning the relation which such a science is able to predicate regard- ing the relation of the two kinds of phenomena with which it deals. It may be said that it is the business of a science, as a science, to discover uniformities of action, invariable se- quences between phenomena. As a science, it knows nothing of any bond linking the phenomena together, or of any action or interaction between antecedent or consequent. It professes only to discover sequences and uniform modes of acting. ^ Scripture, " The Problem of Psychology," Mind, No. 63. 50 The Will. Nevertheless, we do call " that antecedent which is invariably present when the phenomena follows, and invariably ab- sent when the latter is absent, other circumstances remain- ing the same, the cause of the phenomena in these circum- stances." Shall we not use the same word in describing the relation between the phenomena with which physiological- psychology deals ? If the word ' cause ' denotes only invariable sequence, there can, of course, be no question about its use in this case. However, it must not be forgotten that, from its employment in describing the relations of phenomena in the material world, the term has taken on some peculiar shades of meaning which are altogether inapplicable in dealing with the phe- nomena of consciousness. This peculiar modification which has come to attach to the word ' cause ' in recent times is the result of the relation of equivalence, which we always think of as obtaining between the cause and effect in the material world.^ By ' equivalence ' we mean that the series is con- ceivably reversible, that cause and effect have the same power of doing work. This fact is expressed in the law of the conservation of energy. This law has come to be an axiom of modern physical science, and is a direct conse- quence of our postulate that the amount of matter in the universe remains constant. Now such a law can have no application for psychology, or for psycho-physics. If this is clearly recognized, it seems to be a mere matter of words whether we shall or shall not use the term ' cause ' to describe the relation between the phenomena with which these sciences deal. If we speak of causal connections between mental states, or between nervous states and states of con- sciousness, we must do it with the express recognition that here the principle of equivalence has no place. The second point of view is that held by the advocates of the so-called 'automaton theory.' This view can not be re- ^Wundt, Ethik,'ist ed., p. 399. The Relation of Mutd and Body. 51 garded as a mere indication of the proper subject-matter of physical and mental science ; it is a metaphysical theory which asserts the impossibilit}'- of any connection whatever between the physical and the mental world. However close and invariable is the connection between bodily movements and states of consciousness, yet in reality^ it is maintained, they go on in entire independence of each other. " But little reflection is required to show that consciousness does not make the mighty difference which is commonly supposed. Consciousness, when it is present, is the light which lightens the process, not the agent in its accomplishment. We are never conscious of the thing until the thing is. Conscious- ness does not go before the event, it only comes into being with its accomplishment." ^ From this point of view con- sciousness is a mere ' epi phenomenon,' a shadow which ' ought not to exist.' The advocates of this theory not only recog- nize the gulf which Descartes pointed out between matter and mind, but they make it absolute. There are three rea- sons urged for thus wrenching the world apart. First, the utter disparateness of the two kinds of phenomena ; secondly (and partly in consequence of the first), the impossibility of conceiving of any action or reaction between the two worlds ; and, thirdly, the direct consequences of the law of the con- servation of energy. All kinds of physical energy, it is said, are comparable be- cause they are all forms of motion, and can be reduced to a common measure, so many foot-pounds of work. States of mind, on the contrary, are incommensurable with any form of motion, and we do not therefore explain anything by refer- ring them to some physical event. Suppose that we grant this to be a valid ground for keeping the two sciences sepa- rate, yet the objection says nothing regarding the ultimate relations of members of the two series. The phenomenal dis- ^Maudsley : "The Cerebral Cortex and its Work." Mind, XV, pp, 171- 72. 52 The Will parateness of the two series may be a reason for prohibiting a science which deals with one set of phenomena from ex- plaining by means of members of the other series ; but there is so far no ground for believing that this disparateness is the ultimate fact. The constant correspondences of the two series, and the fact, upon which I shall not dwell here, of the adapta- tion of the bodily movements to the external environment, forbids us to suppose that such an assertion as that of the au- tomatists is a final statement regarding the nature of the two series. There still remains the rational demand that the seeming disparateness of these spheres shall be harmonized. And the very fact that the phenomena of these two fields are manifested in conjunction, not only strengthens our belief in their ultimate unity, but shows that reconciliation is not im- possible. In the second place, it is asserted that the action of con- sciousness on brain, or of brain on consciousness is incon- ceivable. ' The passage from the physics of the brain to the facts of consciousness is unthinkable, ' and by unthinkable is meant picturable, " continuously imaginable.^ " It seems to me that, as before remarked, while this may be an argument for refusing to entangle psychology with physiological ex- planations, it can say nothing regarding the ultimate connec- tion of the different varieties of the real. The word ' incon- ceivable ' has, as Mill pointed out,- three meanings at least. Anything ma}^ be termed inconceivable which we are unable to believe. Thus it was inconceivable to the French peasant girl that the Germans could take Paris. Or, secondly, the term may refer to something which contradicts a fundamental law of our thinking, as that two and two should amount to five. Thirdly, any thing or any event may be pronounced inconceivable when we are unable to represent it by an image in our con- sciousness. It is manifestly in this last sense that action or ^ Miinsterherg. Die WiUenshandhing , p. 27. ''■Examination of Sir William Hamilton's Philosophy, p. 150. The Relation of Mmd and Body, 53 reaction between brain and consciousness is held to be in- conceivable. I can not picture to myself how ' the idea of a beefsteak should bind together molecules ' in such a way as in any way to modify my movements. We may say in general that we can only represent to ourselves what has been first presented. Since, then, this act on the part of consciousness (supposing it to take place) is never immediately known, it is plain that it must forever remain in this sense of the word 'inconceivable.' We are apt, however, to talk as if there is no difficulty in conceiving just how one physical body acts upon another. The fire melts the wax before our eyes ; but, after Hume, we are compelled to admit that we have given only an antecedent and consequent, and know nothing of any bond which unites them. We can say too that after Lotze's analysis,' it is impossible to think of any state, or of any action, as passing over from cause to effect. Modern physicists, too, are abandoning the conception of a force which detaches itself from one object, and attaches itself to another, and beginning to admit that they know nothing regarding the nature of force at all — or rather to doubt whether or not there is anything which corresponds to that conception. It seems then the reciprocal action of brain and mind is incon- ceivable, in the sense that it is not ' continuously imagin- able ' how any one thing acts upon any other. We may per- haps admit that there is more difficulty in conceiving how any reaction could take place between mental and material phenomena, than there is in the case of physical causation, but this difference is not sufficient support for a metaphysical theory. The third, and perhaps the strongest argument for the inde- pendence of the two series, is taken from the law of the con- servation of energy. " According to the causal principle everywhere maintained in physiological investigations, we can speak of a causal connection between phenomena, only IvOtze, Metaphysics, Book I, Chap. V. 54 The Will, when the effect can be derived from the cause according to definite laws. Such a derivation is possible only when we are dealing with homogenous phenomena. This derivation is consequently either thinkable or actually performable in the entire realm of outer phenomena, since an analysis al- ways leads back to some form of motion where the effect is represented as equivalent to the cause. That is, under spe- cial conditions, the causal relation can be reversed. . . It is evident that there can be no question of such an equiva- lence between our representations and the physiological phe- nomena which accompany them. As the effects of the latter, nothing but physical phenomena can ever come into existence. In this way alone is that closed system of nature possible which finds its most perfect expression in the law of the con- servation of energy. This law would be violated if any- where a physical cause should bring about a mental effect." ^ Thus also Scripture, in the article quoted above, writes : " There is one fundamental axiom on which Psychology can work, and without which it becomes involved in the mazes of theory. Mental phe7io7nena can not itifiuence^ or be i?ijlii- enced by 7naterial phe7i07nena. . . The discovery, the de- velopment, and the proof of the law of the conservation of energy by ]\Iayer, Helmholtz, and Joule, have rendered the opposite of the axiom inconceivable.'' - There can be no objection to these statements, in so far as they are to be understood merely as pre- scribing the limit for the physical sciences. It is a work- ing postulate of physiology, that material phenomena shall not be explained by anything except material phenomena ; and of psychology that ps\chical states shall be referred only to some antecedent psychical states. Yet this is not quite the same thing as the assertion which is so often made that ' mental phenomena can not influence, or be influ- ^ Wundt, Essays^ Gchini und Seele. ^ Scripture, " The Problem of Psychology," M:?id, Xo. 63. The Relation of Mind and Body. 55 enced by physical phenomena.' Such a statement seems to dogmatise regarding the metaphysical question concerning the ultimate nature of body and mind. If it is true that the as- sertion is to be regarded as indicating the final truth regarding phenomenal facts — that in reality one set of phenomena pro- ceeds in entire independence of the other — it is difficult to understand how any metaphysical theory can overcome the dualism. Or, perhaps, it would be better to say that the state- ment is a metaphysical theory. But if, on the other hand, it is only intended to indicate the mode of procedure of the physical sciences, and the ideal which psychology must hold up for it- self, we must keep constantly in mind that this division is only a methodological one, and not a statement regarding reality itself. This is all that the writers from whom I have quoted mean to convey ; yet it seems to me that they have stated what is an axiom of science regarding its own mode of ex- plaining facts, as if it were an expression of the ultimate nature of these facts themselves. In the same way, it is not unusual for psychologists to take high ground when dealing with the law of the conservation of energy. It is not uncommon to find it referred to as ' proven by Mayer, Helmholtz, and Joule,' or as ' 2. fact that has now been fully demonstrated.' A little consideration, how- ever, shows us that the law has never been proved — nor can it ever be — in the universal sense claimed for it. It would of course be forever impossible for physiologists, by means of ac- tual measurements, to demonstrate that the nervous processes which are attended by consciousness, do not influence the latter in any way, and are entirely uninfluenced by it. The law has been verified, with greater or less exactitude, in fields where consciousness can not be thought of as a factor. There has been no disproof of the influence of consciousness ; and, from the very nature of the case, there can be none. But it is sometimes claimed that although experience can never demonstrate to us this law, it is really identical with a law of our thought, being another form of the law of 56 The Will persistence of matter/ To make this law a necessity of our thought, is simply an absurdity, in face of the fact that the ma- jority of mankind have never heard of it, and that many sci- entists do not understand it as anything more than ' a leading principle of natural science ;' ^ or 'a valid and useful working hypothesis under which we may bring certain classes of physi- cal phenomena.' As Professor Ladd says: "Even in the sphere of physical events, the law is as yet demonstrably true only to a limited extent. The various forms of physical en- ergy in the inorganic world are by no means yet all reducible to the terms of this law. . . . No mathematical formula, or picture framed by the imagination, has thus far bridged over the gap between the molecular energy of inorganic and that of organic structures. . . . Nerve force — what it is and what it will do ; what it is as judged by what it will do — cannot at present be correlated with any of the forms of energy which act as nervous stimuli.''^ ]\Iany examples might be given, not only of the incompleteness, but also of the actual impossibility of reducing all causal relations under the law of the correlation and conservation of physical energy. The ideal physical explanation is thus formulated by Du Bois Reymond : " Before the differential equations of the world formula can be formed, all natural phenomena must be re- duced to the movements of a substratum substantially homo- geneous, and therefore entirely destitute of quality, or of that which appears to us as heterogeneous matter — in other words all quality must be explained by the arrangement and motion of such a substratum."* Now, however far physical science may be from the attain- ment of such an ideal, it is useless to deny that its adoption has led to enormous advancement in the work of understand- ^Miinsterberg, Die Willenshandlung, p. 9. ^Hoffding, Outlines of Psychology, (Eng. trans.), p. 5S.

Mod- ern physiology owes, perhaps, all its success to the adoption of this point of view, and its abandonment of the principle of ' vital force.' In accordance with this principle, every change in the organism has its ' chemical or ph3'sical equivalent either in the organism or without it.' Such hypotheses have justi- fied their adoption by proving themselves useful ; i. Tow-ls^ip. PA 16066 (724) 779-21 1 1 LIBRARY OF CONGRESS 014 137 322 5 # fM* r i If.
