HENRY SIDGWICK LONDON KEGAN PAUL, TRENCH, TRUBNER & CO., LTD. BROADWAY HOUSE, CARTER LANE, E.G. NEW YORK: E. P. DUTTON AND CO. 1918 7 2^ EDITOR'S PREFACE ^f TO THE PRESENT ABRIDGED EDITION Phantasms of the Living, published in 1886, which embodies much of the early work of the Society for Psychical Research, and in particular much valuable discussion by its earliest honorary secretary, Edmund Gurney, has long been out of print. But as its value has been but little aflEected by subsequent investigations, and it still forms the basis on which much of the present-day work on telepathy, and especially on apparitions, rests, it is thought that a new edition is likely to be appre- ciated by the public. Had the authors been with us still, a new edition would no doubt have been brought up to date. New evidence would have been included, and the discussion might perhaps have been added to or diminished, to suit the new atmosphere which the book itself has helped to create. Changes of this sort I have not felt justified in attempt- ing. The text is subst antially as jbhe^uthors left it w ith t he_ exception of omissions for the s ake of^brevity^in^ Chapte rs IV and XIII ( indicatedjn their place s), an d no new cases h ave been introduced . The original edition, however, occupies two large volumes and it was desired to reduce the present one by nearly half. This has been effected mainly by omitting a large number of the cases quoted. In the original work, besides descriptions of experiments, accounts of some 700 numbered incidents, prima facie telepathic, were given. Of these the present edition includes only 186. The whole of the supplement which contains more than half the c ases — the less well-evidenced ones — has been omitted. Of the rest the cases retained are selected first as required to illustrate Gurney 's remarks, and secondly as being, in my judgment, the best evidenced of their class. They must be regarded as typical cases, not as exhibiting the mass of evidence obtainable at the time, and which for reasons explainc I in the introduction, it was an important part of the plan of the original work to present. In order to retain as far as possible the effect of this mass, I have given the cases their original numbers, thus showing how many have been omitted at each point. Further omissions for the sake of brevity are some experimental cases ; some illustrative cases in foot-notes ; and, more important, a long note by Gurney on Witchcraft and one by Myers " On a Suggested Mode of Psychical Interaction," neither of which belongs to the general course of the work. It remains to explain that I have inserted in their proper places some of the cases from the "Additional Chapter" of the original edition, and have introduced further information about a few cases and other matters, not only from Gurney 's " Additions and Corrections," but from other sources, especially from articles published by Gurney himself in reply to criticisms. A few foot-notes, attached to omitted cases, have been viii EDITOR'S PREFACE TO THE ABRIDGED EDITION transferred to equally appropriate places elsewhere. Finally there are a very few editorial notes in text and foot-notes. These are clearly dis- tinguished by being enclosed in square brackets and signed " Ed." Square brackets were also used by Gurney to indicate remarks of his own in the course of cases, but there is I think no risk of confusion. The omission of cases has necessitated some changes in sentences connecting one case with another. These also, when other than purely verbal, have been enclosed in square brackets. I must in conclusion remind readers, especially those who have not followed regularly the Proceedings of the Society for Psychical Research, that the present work, excellent as I think it is, cannot now be regarded as a complete exposition of the subject with which it deals. In the thirty-one years since it was originally published, much new and illuminat- ing evidence for telepathy — both experimental and spontaneous — has been accumulated ; our knowledge about transient hallucinations of the sane {see Chap. XI), veridical and other, has been considerably added to by the " Census of Hallucinations," of which the results were published in Proceedings, vol. x ; motor automatism, in the form especially of automatic writing, has been much studied ; and finally evidence pointing to the operation of telepathy, not only between minds in the body, but between the living and the dead, has so much increased, that had he written now I think it probable that Gurney (as well as Myers) would have referred to this possibility less tentatively than he does on pages 331 and 479-481. ELEANOR MILDRED SIDGWICK. Office of the Society for Psychical Research, 20, Hanover Square, W. January, 191 8. PREFACE TO ORIGINAL EDITION A LARGE part of the material used in this book was sent to the authors as representatives of the Society for Psychical Research ; and the book is published with the sanction of the Council of that Society. The division of authorship has been as follows. As regards the writing and the views expressed, — Mr. Myers is solely responsible for the Intro- duction, and for the " Note on a Suggested Mode of Psychical Inter- action," which immediately precedes the Supplement ; and Mr. Gurney is solely responsible for the remainder of the book. But the most difficult and important part of the undertaking — ^the collection, examination, and appraisal of evidence — has been a joint labour, of which Mr. Podmore has borne so considerable a share that his name could not have been omitted from the title-page. In the free discussion and criticism which has accompanied the progress of the work, we have enjoyed the constant advice and assist- ance of Professor and Mrs. Sidgwick, to each of whom we owe more than can be expressed by any conventional phrases of obligation. Whatever errors of judgment or flaws in argument may remain, such blemishes are certainly fewer than th'ey would have been but for this watchful and ever -ready help. Professor and Mrs. Sidgwick have also devoted some time and trouble, during vacations, to the practical work of interviewing informants and obtaining their personal testimony. In the acknowledgment of our debts, special mention is due to Pro- fessor W. F. Barrett. He was to a great extent the pioneer of the move- ment which it is hoped that this book may carry forward ; and the extent of his services in relation, especially, to the subject of experi- mental Thought-transference will sufficiently appear in the sequel. Mr. Malcolm Guthrie, Professor Oliver J. Lodge, and M. Charles Richet have been most welcome allies in the same branch of the work. Professor Barrett and M. Richet have also supplied several of the non-experimental cases in our collection. Mr. F. Y. Edgeworth has rendered valuable assistance in points relating to the theory of probabilities, a subject on which he is a recognised authority. Among members of our own Society, our warmest thanks are due to Miss Porter, for her well-directed, patient, and energetic assistance in every department of the work ; Mr. C. C Massey has given us the benefit of his counsel ; and Mrs. Walwyn, X PREFACE TO ORIGINAL EDITION Mr. Hensleigh Wedgwood, the Rev. A. T. Fryer, of Clerkenwell, the Rev. J. A. Macdonald, of Rhyl, and Mr. Richard Hodgson, have aided us greatly in the collection of evidence. Many other helpers, in this and other countries, we must be content to include in a general expression of gratitude. Further records of experience will be most welcome, and should be sent to the [office of the Society for Psychical Research.] June, 1886. SYNOPSIS INTRODUGTION § I. The title of this book embraces all transmissions of thought and feeling fi-om one person to another, by other means than through the recognised channels of sense ; and among these cases we shall include apparitions . . . xxxiii § 2. We conceive that the problems here attacked lie in the main track of science ........... xxxiii-xxxiv § 3. The Society for Psychical Research merely aims at the free and exact discussion of the one remaining group of subjects to which such discussion is still refused. Reasons for such refusal ..... xxxiv-xxxvi § 4. Reasons, on the other hand, for the prosecution of our inquiries may be drawn from the present condition of several contiguous studies. Reasons drawn from the advance of biology ....... xxxvi-xxxvii § 5. Specimens of problems which biology suggests, and on which inquiries like ours may ultimately throw light. Wundt's view of the origination of psychical energy ........ xxxvii-xxxviii § 6. The problems of hypnotism ..... xxxviii-xxxix § 7. Hope of aid from the progress of " psycho-physical " inquiries xxxix-xl § 8. Reasons for psychical research drawn from the lacuncs of anthro- pology ............ xl-xli § g. Reasons drawn from the stud}' of history, and especially of the com- parative history of religions. Instance from the S.P.R.'s investigation of so- called " Theosophy " . . . . . . . . xli-xliii § 10. In considering the relation of our studies to religion generally, we observe that, since they oblige us to conceive the psychical element in man as having relations which cannot be expressed in terms of matter, a possibilitj- is suggested of obtaining scientific evidence of a supersensory relation between man's mind and a mind or minds above his own .... xliii-xlv § II. While, on the other hand, if our evidence to recent supernormal occurrences be discredited, a retrospective improbability will be thrown on much of the content of religious tradition ..... xlv-xlvii § 12. Furthermore, in the region of ethical and aesthetic emotion, telepathy indicates a possible scientific basis for much to which men now cling without definite justification ......... xlvii-1 § 13. Investigations such as ours are important, moreover, for the purpose of checking error and fraud, as well as of eliciting truth . . . 1-li II § 14. Place of the present book in the field of psychical research. Indications of experimental thought-transference in the normal state. 1 876-1 882 . li-lii § 15. Foundation of the Society for Psychical Research, 1882. Telepathy selected as our first subject for detailed treatment on account of the mass of evidence for it received by us . . . . . . . . lii-liii § 16. There is also a theoretic fitness in treating of the direct action of mind upon mind before dealing with other supernormal phenomena . . liii-liv § 17. Reasons for classing apparitions occurring about the moment of death as phantoms of the living, rather than of the dead .... liv-lvi xii SYNOPSIS § i8. This book, then, claims to show (i) that experimental telepathy exists, and (2) that apparitions at death, &c., are a result of something beyond chance ; whence it follows (3) that these experimental and these spontaneous cases of the action of mind on mind are in some way allied ..... Ivi-lvii § 19. As to the nature and degree of this alliance different views may be taken, and in a " Note on a Suggested Mode of Psychical Interaction " [omitted in the present edition. — Ed.] a theory somewhat different from Mr. Gurnej^'s is set forth .......... Ivii-lix § 20. This book, however, consists much more largely of evidence than of theories. This evidence has been almost entirely collected by ourselves lix-lx § 21. Inquiries like these, though they may appear at first to degrade great truths or solemn conceptions, are likely to end by exalting and affirming them ............ Ix CHAPTER I Preliminary Remarks : Grounds of Caution § I. The great test of scientific achievement is often held to be the power to predict natural phenomena ; but the test, though an authoritative one in the sciences of inorganic nature, has but a limited application to the sciences that deal with life, and especially to the department of mental phenomena . 1-2 § 2. In dealing with the implications of life and the developments of human faculty, caution needs to be exercised in two directions. The scientist is in danger of forgetting the unstable and unmechanical nature of the material, and of closing the door too dogmatically on phenomena whose relations with estab- lished knowledge he cannot trace ; while others take advantage of the fact that the limits of possibility cannot here be scientificall}^ stated, to gratify an uncritical taste for marvels, and to invest their own hasty assumptions with the dignitj^ of laws . . . . . . . . . . . . 3-4 § 3. This state of things subjects the study of " psychical " phenomena to peculiar disadvantages, and imposes on the strident peculiar obligations . 4-5 § 4. And this should be well recognised by those who advance a conception bo new to psychological science as the central conception of this book — to wit, Telepathy, or the ability of one mind to impress or to he impressed by another mind otherwise than through the recognised channels of sense. (Of the two persons concerned, the one whose mind impresses the other will be called the agent, and the one whose mind is impressed the percipient) ..... 5-6 § 5. Telepathy will be here studied chiefly as a system of facts, theoretical discussion being subordinated to the presentation of evidence. The evidence will be of two sorts — spontaneous occurrences, and the results of direct experi- ment ; which latter will have to be carefully distinguished from spurious " thought-reading " exhibitions ....... 6-7 CHAPTER II The Experimental Basis : Thought-Transference § I . The term thought-transference has been adopted in preference to thought- reading, the latter term (i) having become identified with exhibitions of miiscle- reading, and (2) suggesting a power of reading a person's thoughts against his will ............ 8-9 § 2. The phenomena of thought-transference first attracted the attention of competent witnesses in connection with " mesmerism," and were regarded as one of the peculiarities of the mesmeric rapport ; which was most prejudicial to their chance of scientific acceptance ....... g-io § 3. Hints of thought-transference between persons in a normal state were obtained by Professor Barrett in 1S76 ; and just at that time the attention of others had been attracted to certain phenomena of the " willing-game," which SYNOPSIS xiii were not easily explicable (as almost all the so-called " willing " and " thought- reading " exhibitions are) by unconscious muscular guidance. But the issue could never be definitely decided by cases where the two persons concerned were in any sort of contact ......... 10-13 § 4. And even where contact is excluded, other possibilities of unconscious guidance must be taken into account ; as also must the possibility of conscious collusion. Anyone who is unable to obtain conviction as to the bona fides of experiments by himself acting as agent or percipient (and so being himself one of the persons who would have to take part in the trick, if trick it were), may fairly demand that the responsibility for the results shall be spread over a con- siderable group of persons — a group so large that he shall find it impossible to extend to all of them the hypothesis of deceit (or of such imbecility as would take the place of deceit) which he might apply to a smaller number . 1 4-1 6 § 5. Experiments with the Creery family ; earlier trials . . . 16-18 More conclusive experiments, in which knowledge of what was to be trans- ferred (usually the idea of a particular card, name, or number) was confined to the members of the investigating committee who acted as agents ; with a table of results, and an estimate of probabilities ...... 18-21 In many cases reckoned as failures there was a degree of approximate success which was very significant . . . . . . . .21-22 The form of the impression in the percipient's mind seems to have been sometimes visual and sometimes auditory ...... 22 § 6. Reasons why these experiments were not accessible to a larger number of observers ; the chief reason being the gradual decline of the percipient faculty ............ 22-24 § 7. In a course of experiments of the same sort conducted by M. Charles Richet, in France, the would-be percipients were apparently not persons of any special susceptibility ; but a sufficient number of trials were made for the excess of the total of successes over the total most probable if chance alone acted to be decidedly striking ........ 24-26 The pursuit of this line of inquiry on a large scale in England has produced results which involve a practical certainty that some cause other than chance has acted ........... 26-27 § 8, Experiments in the reproduction of diagrams and rough drawings. In a long series conducted by Mr. Malcolm Guthrie, two percipients and a consider- able number of agents were employed ...... 27-30 Specimens of the results . . . . . . . . 30-40 § 9. Professor Oliver J. Lodge's experiments with Mr. Guthrie's " subjects," and his remarks thereon ......... 41-43 § 10. Experiments in the transference of elementary sensations — tastes, smells, and pains .......... 43-48 § II. A different department of experiment is that where the transference does not take effect in the percipient's consciousness, but is exhibited in his motor system, either automatically or semi-automaticaUy. Experiments in the inhibition of utterance ......... 48-50 § 12. The most conclusive cases of transference of ideas which, nevertheless, do not affect the percipient's consciousness are those where the idea is repro- duced by the percipient in writing, without his being aware of what he has written. Details of a long series of trials carried out by the Rev. P. H. and Mrs. Newnham .......... 50-56 The intelligence which acted on the percipient's side in these experiments was in a sense an unconscious intelligence — a term which needs careful definition 56-57 § 13. M. Richet has introduced an ingenious method for utilising what he calls " mediumship " — i.e., the liability to exhibit intelligent movements in which consciousness and will take no part — for purposes of telepathic experi- ment. By this method it has been clearly shown that a word on which the agent concentrates his attention may be unconsciously reproduced by the percipient ........... 57-61 And even that a word which has only an unconscious place in the agent's mind may be similarly transferred ....... 61-64 These phenomena seem to involve a certain impulsive quality in the trans- ference ............ 64-65 xiv SYNOPSIS § 14. Apart from serious and systematic investigation, interesting results are sometimes obtained in a more casual way, of which some specimens are given. It is much to be wished that more persons would make experiments, under conditions which preclude the possibility of unconscious guidance. At present we are greatly in the dark as to the proportion of people in whom the specific faculty exists ......... 65-69 CHAPTER III The Transition from Experimental to Spontaneous Telepathy § I. There is a certain class of cases in which, though they are experiments on the agent's part, and involve his conscious concentration of mind with a view to the result, the percipient is not consciously or voluntarily a party to the experiment. Such cases may be called transitional. In them the distance between the two persons concerned is often considerable . . . -70 § 2. Spurious examples of the sort are often adduced ; and especially in connection with mesmerism, results are often attributed to the operator's will, which are really due to some previous command or suggestion. Still, examples are not lacking of the induction of the hypnotic trance in a " subject " at a distance, by the deliberate exercise of volition ..... 70-72 § 3. Illustrations of the induction or inhibition of definite actions by the agent's volition, directed towards a person who is unaware of his intent 72-74 The relation of the will to telepathic experiments is liable to be misunder- stood. The idea, which we encounter in romances, that one person may acquire and exercise at a distance a dangerous dominance over another's actions, seems quite unsupported by evidence. An extreme example of what may really occur is given ........... 74-76 § 4. Illustrations of the induction of definite ideas by the agent's volition ............ 76 § 5. The transference of an idea, deliberately fixed on by the agent, to an unprepared percipient at a distance, would be hard to establish, since ideas whose origin escapes us are so constantly suggesting themselves spontaneously. Still, telepathic action may possibly extend considerably beyond the well- marlced cases on which the proof of it must depend .... 76-77 § 6. Illustrations of the induction of sfiKsa^iOKS by the agent's volition 77-79 § 7. And especially of sensations of sight ..... 79-82 § 8. The best-attested examples being hallucinations representing the figure of the agent himself ......... 82-92 § 9. Such cases present a marked departure from the ordinary type of experimental thought-transference, inasmuch as what the percipient perceives (the agent's form) is not the reproduction of that with which the agent's mind has been occupied ; and this seems to preclude any simple physical conception of the transference, as due to " brain-waves," sympathetic vibrations, &c. A similar difficulty meets us later in most of the spontaneous cases ; and the rapprochement of experimental and spontaneous telepathy must be understood to be limited to their psychical aspect — a limitation which can be easily defended ........... 92-94 CHAPTER IV General Criticism of the Evidence for Spontaneous Telepathy § I. When we pass to spontaneous exhibitions of telepathy, the nature of the evidence changes ; for the events are described by persons who played their part in them unawares, without any idea that they were matter for scientific observation. The method of inquiry will now have to be the historical method, and will involve difficult questions as to the judgment of human testimony, and a complex estimate of probabilities ....,., 95-96 SYNOPSIS XV § 2. The most general objection to evidence for phenomena transcending the recognised scope of science is that, in a thickly populated world where mal-observation and exaggeration are easy and common, there is (within certain limits) no marvel for which evidence of a sort may not be obtained. This objection is often enforced by reference to the superstition of witchcraft, which in quite modern times was supported by a large array of contemporary evidence ........... 96 But when this instance is carefully examined, we find (i) that the direct testimony came exclusively from the uneducated class ; and (2) that, owing to the ignorance which, in the witch-epoch, was universal as to the psychology of various abnormal and morbid states, the hypothesis of unconscious self-deception on the part of the witnesses was never allowed for .... 96-97 Our present knowledge of hypnotism, hysteria, and hystero-epilepsy enables us to account for many of the phenomena attributed to demonic possession, as neither fact nor fraud, but as bona fide hallucinations . . . -97 While for the more bizarre and incredible marvels there is absolutely no direct, first-hand, independent testimony ..... 98-99 The better-attested cases are just those which, if genuine, might be explained as telepathic ; but the evidence for them is not strong enough to support any definite conclusion ......... 99-100 § 3. The evidence for telepathy in the present work presents a complete contrast to that which has supported the belief in magical occurrences. It comes for the most part from educated persons, who were not predisposed to admit the reality of the phenomena ; while the phenomena themselves are not strongly associated with any prevalent beliefs or habits of thought, differing in this respect, e.g., from alleged apparitions of the dead. Still we must not, on such grounds as these, assume that the evidence is trustworthy . . 101-102 § 4. The errors which may affect it are of various sorts. Error of observation may result in a mistake of identity. Thus a stranger in the street may be mistaken for a friend, who turns out to have died at that time, and whose phantasm is therefore asserted to have appeared. But it is only to a very small minority of the cases which follow that such a hypothesis could possibly be applied 102-103 Error of inference is not a prominent danger ; as what concerns the tele- pathic evidence is simply what the percipient seemed to himself to see or hear, not what he inferred therefrom ....... 103-104 § 5. Of more importance are errors of narration, due to the tendency to make an account edifying, or graphic, or startling. In first-hand testimony this tendency may be to some extent counterbalanced by the desire to be believed ; which has less influence in cases where the narrator is not personally responsible, as, e.g., in the spurious and sensational anecdotes of anonymous newspaper paragraphs, or of dinner-table gossip ...... 104-106 § 6. Errors of memory are more insidious. If the witness regards the facts in a particular speculative or emotional light, facts will be apt, in memory, to accommodate themselves to this view, and details will get introduced or dropped out in such a manner as to aid the harmonious effect. Even apart from any special bias, the mere effort to make definite what has become dim may fill in the picture with wrong detail ; or the tendency to lighten the burden of retention may invest the whole occurrence with a spurious trenchancy and simplicity of form ............ 106-108 § 7. We have to consider how these various sources of error may affect the evidence for a case of spontaneous telepathy. Such a case presents a coincidence of a particular kind, with four main points to look to : — (i) A particular state of the agent, e.g., the crisis of death ; (2) a particular experience of the percipient, e.g., the impression of seeing the agent before him in visible form ; (3) the date of (i) ; (4) the date of (2) 108 § 8. The risk of mistake as to the state of the agent is seldom appreciable : his death, for instance, if that is what has befallen him, can usually be proved beyond dispute .......... 108-109 For the experience of the percipient, on the other hand, we have generally nothing but his own word to depend on. But for what is required, his word is often sufficient. For the evidential point is simply his statement that he has had an impression or sensation of a peculiar kind, which, if he had it, he knew that xvi SYNOPSIS he had ; and this point is quite independent of his interpretation oi. his experi- ence, which may easily be erroneous, e.g., if he attributes objective realitj' to what was really a hallucination . . . . . . . .109 The risk of misrepresentation is smallest if his description of his experience, or a distinct course of action due to his experience, has preceded his knowledge of what has happened to the agent ...... 109-110 § 9. Where his description of his experience dates from a time subsequent to his knowledge of what has happened to the agent, there is a possibility that this knowledge may have made the experience seem more striking and distinctive than it really was. Still, we have not detected definite instances"of this sort of inaccuracy. Nor would the fact (often expressly stated by the witness) that the experience did not at the time of its occurrence suggest the agent, by any means destroy — though it would of course weaken — the presumption that it was telepathic ........... 111-112 I 10. As regards the interval of time which may separate the two events or experiences on the agent's and the percipient's side respectively, an arbitrary limit of 12 hours has been adopted — the coincidence in most cases being very much closer than this ; but no case will be presented as telepathic where the percipient's experience preceded, by however short a time, some grave event occurring to the agent, if at the time of the percipient's experience the state of the agent was normal ......... 112-113 § II. It is in the matter of the dates that the risk of misstatement is greatest. The instinct towards simplification and dramatic completeness naturally tends to make the coincidence more exact than the facts warrant . . 1 14-115 § 12. The date of the event that has befallen the agent is often included in the news of that event ; which news, in these days of posts and telegraphs, often follows close enough on the percipient's experience for the date of that experience to be then safely recalled ..... ... 11 5-1 16 § 13. But if a longer interval elapse, the percipient may assume too readily that his own experience fell on the critical day ; and as time goes on, his certainty is likely to increase rather than diminish. Still, if the coincidence was then and there noted, and if the attention of others was called to it, it may be possible to present a tolerably strong case for its reality, even after the lapse of a con- siderable time .......... 116-117 § 14. These various evidential conditions may be arranged in a graduated scheme ........... 11 7-1 19 § 15. Second-hand evidence (except of one special type) is excluded from the body of the work ; but the Supplement [omitted in this edition. — Ed.] contains a certain number of second-hand cases, received from persons who were well acquainted with the original witnesses, and who had had the opportunity of becoming thoroughly acquainted with their statement of the facts . 1 19-120 § 16. A certain separation of cases according to their evidential value has been attempted, the body of the work being reserved for those where the primd Jade probability that the essential facts are correctly stated is tolerably strong. But even where the facts are correctly reported, their force in the argument for telepathy will differ according to the class to which they belong ; purely emotional impressions, for instance, and dreams, are very weak classes . . 120-12 1 The value of the several items of evidence is also largely affected by the mental qualities and training of the witnesses. Every case miist be judged on its own merits, by reference to a variety of points ; and those who study the records will have an equal opportunity of forming a judgment with those who have collected them — except in the matter of personal acquaintance with the witnesses, the effect of which it is impossible to communicate . . 121-123 § 17. An all-important point is the number of the coincidences adduced. A few might be accounted accidental ; but it will be impossible to apply that hypothesis throughout. Nor can the evidence be swept out of court by a mere general appeal to the untrustworthiness of human testimony. If it is to be explained away, it must be met (as we have ourselves endeavoured to meet it) in detail ; and this necessitates the confronting of the single cause, telepathy (whose d priori improbability is fully admitted), Avith a multitude of causes, more or less improbable, and in cumulation incredible .... 123-124 i_§ 18. With all their differences, the cases recorded bear strong signs of SYNOPSIS xvii belonging to a true natural group ; and their harmony, alike in what they do and in what they do not present, is very unlikely to be the accidental result of a multitude of disconnected mistakes. And it is noteworthy that certain sensa- tional and suspicious details, here conspicuous by their absence, which often make their way into remote or badly-evidenced cases, are precisely those which the telepathic hypothesis would not cover ..... 124-126 § 19. But though some may regard the cumulative argument here put forward for spontaneous telepathy as amounting to a proof, the proof is not by any means of an eclatant sort : much of the evidence falls far short of the ideal standard. Still, enough has perhaps been done to justify our undertaking, and to broaden the basis of future inquiry ...... 126-128 § 20. The various items of evidence are, of course, not the links in a chain, but the sticks in a faggot. It is impossible to lay down the precise number of sticks necessary to a perfectly solid faggot ; but the present collection is at least an instalment of what is required ....... 128-129 § 21. The instinct as to the amount of evidence needed may differ greatly in a mind which has, and a mind which has not, realised the facts of experimental telepathy (Chap, ii.), and the intimate relation of that branch to the spontaneous branch. Between the two branches, in spite of their difference — a difference as great in appearance as that between lightning and the electrical attraction of rubbed amber for bits of straw — the great psychological fact of a supersensuous influence of mind on mind constitutes a true generic bond . . . 129-130 [The following is Gurney's Synopsis of his important Note on Witchcraft Omitted in the present Edition. — Ed.] The statement made in Chapter iv. as to the lack of first-hand evidence for the phenomena of magic and witchcraft (except so far as they can be completely accounted for by modern psychological knowledge) may seem a sweeping one. But extensive as is the literature of the subject, the actual records are extra- ordinarily meagre ; and the staple prodigies, which were really nothing more than popular legends, are quoted and re-quoted ad nauseam. Examples of the so-called evidence which supported the belief in lycanthropy, and in the nocturnal rides and orgies. The case of witchcraft, so far from proving (as is sometimes represented) that a more or less imposing array of evidence will be forthcoming for any belief that does not distinctly fly in the face of average public opinion, goes, in fact, rather surprisingly far towards proving the contrary ..... This view of the subject is completely opposed to that of Mr. Lecky, whose treatment seems to suffer from the neglect of two important distinctions. He does not distinguish between evideitce — of which, in respect of the more bizarre marvels, there was next to none ; and authority — of which there was abundance, from Homer downwards. Nor does he discriminate the wholly incredible allega- tions {e.g., as to transportations through the air and transformations into animal forms) from the pathological phenomena, which in the eyes of comtemporaries were equally supernatural, and for which, as might be expected, the direct evidence was abundant. A most important class of these pathological phenomena were subjective hallucinations of the senses, often due to terror or excitement, and sometimes probably to hypnotic suggestion, but almost invariably attributed to the direct operation of the devil. Other phenomena — of insensibility, inhibition of utterance, abnormal rapport, and the influence of reputed witches on health — were almost certainly hj^notic in character ; " possession " is often simply hystero-epilepsy ; while rauch may be accounted for by mere hysteria, or by the same sort of faith as produces the modern " mind-cures." Learned opinion on the subject of witchcraft went through curious vicissi- tudes ; the recession to a rational standpoint, which in many ways was of course a sceptical movement, being complicated by the fact that many of the phenomena were too genuine to be doubted. Now that the separation is complete, we see that the exploded part of witchcraft never had any real e^ddential foundation ; xviii ' SYNOPSIS while the part which had a real evidential foundation has been taken up into orthodox physiological and psychological science. With the former part we might contrast, and with the latter compare, the evidential case for telepathy, CHAPTER V Specimens of the Various Types of Spontaneous Telepathy § I. As the study of any large amount of the evidence that follows is a task for which many readers will be disinclined, a selection of typical cases will be presented in this chapter, illustrative of the various classes into which the phenomena fall .......... 131-132 § 2. The logical starting-point is found in the class that presents most analogy to experimental thought-transference — i.e., where the percipient's impression is not externalised as part of the objective world. An example is given of the transference of pain, and a possible example of the transference of smell ; but among the phenomena of spontaneous telepathy, such literal repro- ductions of the agent's bodily sensation are very exceptional . . 132-135 § 3. Examples of the transference of a somewhat abstract idea ; of a pictorial image ; and of an emotional impression, involving some degree of physical dis- comfort ........... 135-141 § 4. Examples of dreams, — a class which needs to be treated with the greatest caution, owing to the indefinite scope which it affords for accidental coincidences. One of the examples (No. 23) presents the feature of deferment of percipience — the telepathic impression having apparently failed at first to reach the threshold of attention, and emerging into consciousness some hours after the experience on the agent's side in which it had its origin ..... 141-146 § 5. Examples of the " borderland " class — a convenient name by which to describe cases that belong to a condition neither of sleep nor of provably com- plete waking consciousness ; but it is probable that in many of the cases so described (as in No. 26), the percipient, though in bed, was quite normally awake ........... 146-151 § 6. Examples of externalised impressions of sight, occurring in the midst of ordinary waking life. In some of these we find an indication that a close personal rapport between the agent and percipient is not a necessary condition of the telepathic transference ; and another is peculiar in that the phantasmal figure is not recognised by the percipient . . . . .151-162 § 7. Examples of externalised impressions of hearing ; one of which was of a recognised voice, and one of an inarticulate shriek .... 162-166 § 8. Example of an impression of touch ; which is also, perhaps, an example of the reciprocal class, where each of the persons concerned seems to exercise a telepathic influence on the other ....... 166-168 § 9. Example of the collective class, where more percipients than one take part in a single telepathic incident . ...... 168-170 § 10. Among the various conditions of telepathic agency, the death-cases form by far the commonest type. Now in these cases it is not rare for the agent to be comatose and unconscious ; in other cases, again, he has been in a swoon or a deep sleep ; and there is a difficulty in understanding an abnormal exercise of psychical energy at such seasons. The explanation may possibly be found in the idea of a wider consciousness, and a more complete self, which finds in what we call life very imperfect conditions of manifestation, and recognises in death not a cessation but a liberation of energy ..... 170-172 SYNOPSIS xix CHAPTER VI Transference of Ideas and Mental Pictures § I. The popular belief in the transference of thought, without physical signs, between friends and members of the same household, is often held on quite insufficient grounds ; allowance not being made for the similarity of associations, and for the slightness of the signs which may be half-automatically interpreted ........... 173-174 It often happens, for instance, that one person in a room begins humming a tune which is running in another's head ; but it is only very exceptionally that such a coincidence can be held to imply a psychical transference. Occasionally the idea transferred is closely connected with the auditory image of a word or phrase ........... 174-175 § 2. Examples of the transference of ideas and images of a simple or rudi- mentary sort .......... 175-177 § 3. Examples of the transference of more complex ideas, representing definite events .......... 177-181 § 4. Cases where the idea impressed on the percipient has been simply that of the agent's approach — a type which must be accepted with great caution, as numerous coincidences of the sort are sure to occur by pure accident . 1 81-183 § 5. Transferences of mental images of concrete objects and scenes with which the agent's attention is occupied at the time .... 183-188 Some of these impressions are so detailed and vivid as to suggest clairvoyance ; nor is there any objection to that term, so long as we recognise the difference between such telepathic clairvoyance, and any supposed independent extension of the percipient's senses ........ 188-189 Occasionally the percipient seems to obtain the true impression, not by passive reception, but by a deliberate effort . . . . . .18$ CHAPTER VII Emotional and Motor Effects § I, Emotional impressions, alleged to have coincided with some calamitous event at a distance, form a very dubious class, as (i) in retrospect, after the calamity is realised, they are apt to assume a strength and definiteness which they did not really possess ; and (2) similar impressions may be common in the soi-disant percipient's experience, and he may have omitted to remark or record the misses — the many instances which have not corresponded with any real event. All cases must, of course, be rejected where there has been any appreci- able ground for anxiety ........ 1 90-1 91 § 2. Examples which may perhaps have been telepathic ; some of which include a sense of physical distress . ...... 191-195 § 3. Examples of such transferences between twins . . . 195-197 § 4. Examples where the primary element in the impression is a sense of being wanted, and an impulse to movement or action of a sort unlikely to have suggested itself in the ordinary course of things .... 197-202 The telepathic influence in such cases must be interpreted as emotional, not as definitely directing, and still less as abrogating, the percipient's power of choice : the movements produced may be such as the agent cannot have desired, or even thought of ........ . 202-204 XX SYNOPSIS CHAPTER VIII Dreams Part I. — The Relation of Dreams to the Argument for Telepathy § I. Dreams comprise the whole range of transition from ideal and emotional to sensory affections ; and at every step of the transition we find instances which may reasonably be regarded as telepathic ..... 205-206 The great interest of the distinctly sensory specimens lies in the fundamental resemblance which they offer, and the transition which they form, to the externalised " phantasms of the living " which impress waking percipients ; the difference being that the dream-percepts are recognised, on reflection, as having been hallucinatory, and unrelated to that part of the external world where the percipient's body is ; while the waking phantasmal percepts are apt to be regarded as objective phenomena, which really impressed the eye or the ear from outside .......... 206-207 § 2. But when we examine dreams in respect of their evidential value — of the proof which they are capable of affording of a telepathic correspondence with the reality — we find ourselves on doubtful ground. For (i) the details of the reality, when known, will be very apt to be read back into the dream, through the general tendency to make vague things distinct ; and (2) the great multitude of dreams may seem to afford almost limitless scope for accidental correspondences of a dream with an actual occurrence resembling the one dreamt of. Any answer to this last objection must depend on statistics which, until lately, there has been no attempt to obtain ; and though an answer of a sort can be given, it is not such a one as would justify us in basing a theory of telepathy on the facts of dreams alone ........ = . 207-208 § 3. Most of the dreams selected for this work were exceptional in intensity ; and produced marked distress, or were described, or were in some way acted on, before the news of the correspondent experience was known. In content, too, they were mostly of a distinct and unusual kind ; while some of them present a considerable amount of true detail ....... 20S-209 And more than half of those selected on the above grounds are dreams of death — a fact easy to account for on the hypothesis of telepathy, and difficult to account for on the hypothesis of accident ..... 209—210 § 4. Dreams so definite in content as dreams of death afford an opportunity of ascertaining what their actual frequency is, and so of estimating whether the specimens which have coincided with reality are or are not more numerous than chance would fairty allow. With a view to such an estimate, a specimen group of 5360 persons, taken at random, have been asked as to their personal experiences ; and, according to the result, the persons who have had a vividly distressful dream of the death of a relative or acquaintance, within the 12 years 1874-1S85, amount to about i in 26 of the population. Taking this datum, it is shown that the number of coincidences of the sort in question that, according to the law of chances, ought to have occurred in the 12 years, among a section of the population even larger than that from which we can suppose our telepathic evidence to be drawn, is only i. Now (taking account only of cases where nothing had occurred to suggest the dream in a normal way), we have encountered 24 such coincidences — i.e., a number 24 times as large as would have been expected on the hj^pothesis that the coincidence is due to chance alone 210-213 Certain objections that might be taken to this estimate are to a considerable extent met by the precautions that have been used . . . 214-215 § 5. The same sort of argument may be cautiously applied to cases wliere the event exhibited in the coincident dream is not, like death, unique, and where, therefore, the basis for an arithmetical estimate is unattainable 215-216 But many more specimens of a high evidential rank are needed, before dreams can rank as a strong integral portion of the argument for telepathy. Meanwhile, it is only fair to regard them in connection with the stronger evidenc e of the waking phenomena ; since in respect of many of them an explanation that is admitted in the waking cases cannot reasonably be rejected . . 216-217 SYNOPSIS xxi Part II. — Examples of Dreams which may be Reasonably Regarded AS Telepathic § I. Examples of similar and simultaneous dreams . . . 217-219 An experience which has coincided with some external fact or condition may be described as a dream, and yet be sufficiently exceptional in character to preclude an application of the theory of chances based on the limitless number of dreams ........... 219-221 § 2. Examples of the reproduction, in the percipient's dream, of a special thought of the agent's, who is at the tim.e awake and in a normal state 221-223 § 3. Examples of a similar reproduction where the agent is in a disturbed state ............ 223-226 § 4. Cases where the agent's personality appears in the dream, but not in a specially pictorial way. Inadmissibility of dreams that occur at times of anxiety, of dreams of trivial accidents to children, and the like . . . 226-230 § 5. Cases where the reality which the eyes of the agent are actually beholding is pictorially represented in the dream. Reasons why the majority of alleged instances must be rejected ........ 230-231 The appearance in the dream of the agent's own figure, which is not pre- sumably occupying his own thoughts, suggests an independent development, by the percipient, of the impression that he receives . . . -232 § 6. The familiar ways in v/hich dreams are shaped make it easy to under- stand how a dreamer might supply his own setting and imagery to a " transferred impression." Examples where the elements thus introduced are few and simple ........... 232-237 § 7. Examples of more complex investiture, and especially of imagery suggestive of death. Importance of the feature of repetition in some of the examples ........... 237-242 § 8. Examples of dreams which may be described as clairvoyant, but which still must be held to imply some sort of telepathic " agency " ; since the per- cipient does not see any scene, but the particular scene with some actor in which he is connected .......... 242-250 CHAPTER IX " Borderland " Cases § I. The transition-states between sleeping and waking — or, more generally the seasons when a person is in bed, but not asleep — seem to be specially favour- able to subjective hallucinations of the senses ; of which some are known as illusions hypnagogiques ; others are the prolongations of dream-images into waking moments ; and some belong to neither of these classes, though experi- enced in the moments or minutes that precede or follow sleep . . 251-254 § 2. It is not surprising that the same seasons should be favourable also to the hallucinations which, as connected with conditions external to the per- cipient, we should describe, not as subjective, but as telepathic . . . 254 As evidence for telepathy, impressions of this " borderland " type stand on an altogether different footing from dreams ; since their incalculably smaller number supplies an incalculably smaller field for the operation of chance 254-255 Very great injustice is done to the telepathic argument by confounding such impressions with dreams ; as where Lord Brougham explains away the co- incidence of a unique " borderland " experience of his own with the death of the friend whose form he saw, on the ground that the " vast number of dreams " give any amount of scope for such " seeming miracles " . . . 255-257 § 3. Examples where the impression was not of a sensory sort . . 257 § 4. Auditory examples. Cases where the sound heard was not ar- ticulate ........... 257-258 Cases where distinct words were heard ..... 258-264 xxii SYNOPSIS § 5. Visual examples : One (No. 168) illustrates the feature of the appear- ance of more than one figure ; and one (No. 170) that of misrecogniiion on the percipient's part . . ........ 264-273 § 6. Cases where the sense of touch was combined with that of . sight or hearing 273-275 § 7. Cases affecting the two senses of sight and hearing . . 275-285 CHAPTER X Hallucinations : General Sketch § I. Telepathic phantasms of the externalised sort are a species belonging to the larger genus of hallucinations ; and the genus requires some preliminary- discussion ............ 286 Hallucinations of the senses are distinguished from other hallucinations by the fact that they do not necessarily imply false belief . . . .287 They may be defined as percepts which lack, but which can only by distinct reflection be recognised as lacking, the objective basis which they suggest; a definition which marks them ofi on the one hand from true perceptions, and on the other hand from remembered images or mental pictures .... 287-289 § 2. The old method of defining the ideational and the sensory elements in the phenomena was very unsatisfactory. It is easy to show that the delusive appearances are not merely imagined, but are actually seen and heard— the hallucination differing from an ordinary percept only in lacking an objective basis; and this is what is implied in the word psycho-sensorial, when rightly under- stood ............ 289-292 § 3. The question as to the physiological starting-point of hallucinations — whether they are of central or of peripheral origin — has been warmly debated, often in a very one-sided manner. The construction of them, which is central and the work of the brain, is quite distinct from the excitation or initiation of them, which (though often central also) is often peripheral — i.e., due to some other part of the body that sets the brain to work ..... 292-294 § 4. This excitation may even be due to some objective external cause, some visible point or mark, at or near the place where the imaginary object is seen ; and in such cases the imaginary object, which is, so to speak, attached to its point, may follow the course of any optical illusion [e.g., doubling by a prism, reflection by a mirror) to which that point is subjected. But such dependence on an external stimulus does not affect the fact that the actual sensory element of the hallucination, in these as in all other cases, is imposed from within by the brain ........... 295-297 § 5. There, are, however, a large number of hallucinations which are centrally initiated, as well as centrally constructed — the excitation being due neither to an external point, nor to any morbid disturbance in the sense-organs themselves. Such, probably, are many visual cases where the imaginary object is seen in free space, or appears to move independently of the eye, or is seen in darkness. Such certainly, are many auditory hallucinations ; some hallucinations of pain ; many hallucinations which conform to the course of some more general delusion ; and hallucinations voluntarily originated ...... 297-305 § 6. Such also are hallucinations of a particular internal kind common among mystics, in which the sensory element seems reduced to its lowest terms ; and which shade by degrees, on the one side into more externalised forms, and on the other side into a mere feeling of presence, independent of any sensory affection ........... 305—309 § 7. A further argument for the central initiation may be drawn from the fact that repose of the sense-organs seems a condition favourable to hallucina- tions ; and the psychological identity of waking hallucinations and dreams cannot be too strongl}^ insisted on . . . . . . . . 309 § 8. As regards the construction of hallucinations — the cerebral process involved in their having this or that particular form — the question is whether it takes place in the specific sensory centre concerned, or in some higher cortical tract ............ 310-312 SYNOPSIS xxiii § 9. There are reasons for considering that both places of construction are available ; that the simpler sorts of hallucination, many of which are clearly " after-images," and which are often also recurrent, may take shape at the sensory centres themselves ; but that the more elaborate and variable sorts must be traced to the higher origin ; and that when the higher tracts are first concerned, the production of the hallucination is due to a downward escape of the nervous impulse to the sensory centre concerned .... 312-317 § 10. The construction of hallucinations in the cortical tracts of the brain, proper to the higher co-ordinations and the more general ideational activities, is perfectly compatible with the view that the specific sensory centres are them- selves situated not below, but in, the cortex ..... 317-318 CHAPTER XI Transient Hallucinations of the Sane : Ambiguous Cases § I. Transient hallucinations of the sane (a department of mental phenomena hitherto but little studied) comprise two classes : (i) hallucinations of purely subjective origin ; and {2) hallucinations of telepathic origin — i.e., " phantasms of the living " which have an objective basis in the exceptional condition of the person whom they recall or represent. Comparing the two classes, we should expect to find a large amount of resemblance, and a certain amount of difference, between them .......... 319-320 § 2. Certain marked resemblances at once present themselves ; as that (generally speaking) neither sort of phenomenon is observably connected with any morbid state ; and that each sort of phenomenon is rare — occurring to a comparatively small number of persons, and to most of these only once or twice in a lifetime .......... 320-321 § 3. But in pressing the comparison further, we are met by the fact that the dividing line between the two classes is not clear ; and it is important to realise certain grounds of mnbigiiity, which often prevent us from assigning an experience with certainty to this class or that ....... 322—323 § 4. Various groups of hallucinations are passed in review; — "after- images " ; phantasmal objects which are the result of a special train of thought ; phantasms of inanimate objects, and of animals, and non-vocal auditory phan- tasms ; visual representations of fragments of human forms ; auditory impres- sions of meaningless sentences, or of groaning, and the like ; and visions of the " swarming " type. Nearly all specimens of these types may safely be referred to the purely subjective class ....... 323-325 It is when we come to visual hallucinations representing complete and natural-looking human forms, and auditory hallucinations of distinct and intelligible words (though here again there is every reason to suppose the majority of the cases to be purely subjective), that the ambiguous cases are principally to be found ; the ground of ambiguity being that either (i) the person represented has been in an only slightly unusual state ; or (2) a person in a normal state has been represented in hallucination to more than one percipient at different times ; or (3) an abnormal state of the person represented has coincided with the representation loosely, but not exactly ; or (4) the percipient has been in a condition of anxiety, awe, or expectancy, which might be regarded as the independent cause of his experience ..... 325—327 § 5. The evidence that mere anxiety may produce sensor}^ hallucination is sufficient greatly to weaken, as evidence for telepathy, any case where that condition has been present ........ 327-330 § 6. The same may be said of the form of awe which is connected with the near sense of death ; and (except in a few " collective " cases) abnormal experi- ences which ha.ve followed death have been excluded from the telepathic evidence, if the fact of the death was known to the percipient. As to the included cases that have followed death by an appreciable interval, reasons are given for pre- ferring the hypothesis of deferred development to that of post mortem influence — though the latter hypothesis would be quite compatible with the psychical con- ception of telepathy ......... 330-332 xxiv SYNOPSIS § 7. There is definite evidence to show that mere expectancy may produce hallucination .......... 332-334 One type which is probably so explicable being the delusive impression of seeing or hearing a person whose arrival is expected .... 334-335 § 8. There is, however, a group of arrival-cases where the impending arrival was unknown or unsuspected by the percipient ; or where the phantasm has included sorne special detail of appearance which points to a telepathic origin 335-33^ CHAPTER XII The Development of Telepathic Hallucinations § I. There are two very principal ways in which phantasms of telepathic origin often resemble purely subjective hallucinations : (i) gradualness of development ; and (2) originality of form or content, showing the activity of the percipient's own mind in the construction ..... 337-338 § 2. Gradual development is briefly illustrated in the purely subjective class 338-339 § 3. And at greater length in the telepathic class. It may exhibit itself (i) in delayed recognition of the phantasm on the part of the percipient 339-342 Or (2) in the way in which the phantasm gathers visible shape . 342—344 Or (3) in the progress of the hallucination through several distinct stages, sometimes affecting more than one sense ..... 344-348 § 4. Originality of constructioji is involved to some extent in every sensory hallucination which is more than a mere revival of familiar images ; but admits of very various degrees ........ 348-349 § 5. In telepathic hallucinations, the signs of the percipient's own con- structive activity are extremely important. For the difference from the results of experimental thought-transference, which telepathic phantasms exhibit, in representing what is not consciously occupying the agent's mind — to wit, his own form or voice — ceases to be a difficulty in proportion as the extent of the im- pression transferred from the agent to the percipient can be conceived to be small, and the percipient's own contribution to the phantasm can be conceived to be large 349-35° It may be a peculiarity of the transferred idea that it impels the receiving mind to react on it, and to embody and project it as a hallucination ; but the form and detail of the embodiment admit — as in dream — of many varieties, depending on the percipient's own idiosyncrasies and associations . 350-352 § 6. Thus the percipient may invest the idea of his friend, the agent, with features of dress or appurtenance that his own memory supplies. (One of the examples given. No. 202, illustrates a point common to the purely subjective and to the telepathic class, and about equally rare in either — the appearance of more than one figure) 352-357 § 7. Or the investing imagery may be of a more fanciful kind — sometimes the obvious reflection of the percipient's habitual beliefs, sometimes the mere bizarrerie of what is literally a " waking dream." Many difficulties vanish, when the analogy of dream is boldly insisted on .... . 357-358 Examples of phantasmal appearances presenting features which would in reality be impossible ......... 358-359 The luminous character of many visual phantasms is specially to be noted, as a feature common to the purely subjective and to the telepathic class . . 359 Examples of imagery connected with ideas of death, and of religion 359-362 § 8. Sometimes, however, the phantasm includes details of dress or aspect which could not be supplied by the percipient's mind. Such particulars may sometimes creep without warrant even into evidence where the central fact of the telepathic coincidence is correctly reported ; but where genuinelj^ observed, they must apparently be attributed to a conscious or sub-conscious image of his own appearance (or of some feature of it) in the agent's mind, to which the percipient obtains access by what may be again described as telepathic clair- voyance. Examples ......... 362-367 SYNOPSIS XXV In cases where the details of the phantasm are such as either mind might conceivably have supplied, it seems simpler to regard them as the contributions of the percipient, than to suppose that a clean-cut and complete image has been transferred to him from indefinite unconscious or sub-conscious strata of the agent's mind .......... 367-368 § 9. The development of a phantasm from the nucleus of a transferred impression is a fact strongly confirmatory of the view maintained in the preced- ing chapters, as to the physiological starting point of many hallucinations. Especially must the hypothesis of centrifugal origin (of a process in the direction from higher to lower centres) commend itself in cases where the experience seems to have implied the quickening of vague associations and distant memories, whose physical record must certainly lie in the highest cerebral tracts . . 369-370 § 10. Summary of the various points of parallelism between purely subjective and telepathic phantasms, whereby their identity as phenomena for the senses seems conclusively established. But they present also some very important contrasts ........... 370-371 CHAPTER XIII The Theory of Chance-Coincidence § I. Assuming the substantial correctness of much of the evidence for phantasms which have markedly coincided with an event at a distance, how can it be known that these coincidences are not due to chance alone ? In examining this question, we must be careful to distinguish waking cases from dreams — in which latter class (as we have seen) the scope for chance-coincidences is in- definitely large .......... 372-374 § 2. The answer to this question depends on two points — the frequency of phantasms which have markedly coincided with real events, and the frequency of phantasms which have not. If the latter class turned out to be extremely large — e.g., if we each of us once a week saw some friends' figure in a place which was really empty — it is certain that occasionally such a subjective delusion would fall on the day that the friend happened to die. The matter is one on which there have been many guesses, and many assertions, but hitherto no statistics 374-376 § 3. To ascertain what proportion of the population have had experience of purely subjective hallucinations, a definite question must be asked of a group large and varied enough to serve as a fair sample of the whole. The difficulty of taking such a census has been much increased by a wide misunderstanding of its purpose 376-377 § 4. But answers have been received from a specimen group of 5705 persons ; and there is every reason to suppose this number sufficient . . 377-379 § 5. It may be objected that persons may have wrongly denied such experi- ences (i) through forgetfulness — ^but the experiences of real importance for the end in view are too striking to be readily forgotten ; (2) by way of a joke or a hoax — but this would lead rather to false confessions than false denials ; (3) in self-defence — but such error as may have been produced by this motive has probably been more than counter-balanced in other ways . . . 379-381 § 6. As to visual hallucinations, representing a recognised face or form — in the last 12 years such an experience has, according to the census, befallen i adult in every 248 ; but it would have had to befall every adult once, and some adults twice, to justify the assumption that the cases recorded in the present work on first-hand testimony, of the coincidence of the experience in question with the death of the person represented, were due to chance. The odds against the accidental occurrence of the said coincidences are counted in trillions . 381-383 § 7. The extreme closeness of some of the coincidences affords the basis for another form of estimate, which shows the improbability of their accidental occurrence to be almost immeasurably great ..... 384-386 And a number of further cases and further considerations remain, by which even this huge total of improbability would be again swelled. The conclusion, therefore, after all allowances, that at any rate a large number of the coincidences here adduced have had some other cause than chance seems irresistible . 386 xxvi SYNOPSIS § 8. An argument of a quite different sort may be drawn from certain pecu- liarities wtiich the group of coincidental hallucinations present, when compared, as a whole, with the general mass of transient hallucinations of the sane 386-389 CHAPTER XIV Further Visual Cases Occurring to a Single Percipient § I. Visual hallucinations may present various degrees of apparent ex- ternalisation, beginning with what is scarcely more than a picture in the mind's eye, and ending with a percept which seems quite on a par with all surrounding objects. Examples of these varieties in telepathic phantasms . . 390-397 § 2. Examples of completely externalised phantasms. One case (No. 242) is remarkable in that the actual percipient had no direct connection with the agent, but was in the vicinity of a person intimately connected with him 397—41 1 § 3. Cases where the hypothesis of illusion or jnistaken identity has to be taken into account. This hypothesis would not exclude a telepathic origin, as telepathic illusions are quite conceivable phenomena. But more probably these cases were hallucinations ; and if so, their telepathic origin would hardly be doubtful. One of them (No. 243) exhibits the point of a previous compact between the agent and percipient, that whichever died first should endeavour to make the other sensible of his presence. Such a compact, latent in either mind, may quite conceivably have some conditioning efficacy .... 412-417 § 4. Cases of a rudimentary type — perhaps of arrested development — not representative of a human form ; they might be compared to a motor effect which is limited to a single start or twitch. The class is too small to carry any conviction on its own account, but its type is not so improbable as might at first appear ........... 417-419 § 5. Certain cases involving no coincidence with any ostensibly abnormal condition of the agent, (i) Instances where several percipients, at different times, have had hallucinations representing the same person, in whom a specific faculty for producing telepathic impressions may therefore be surmised 419—426 § 5. And (2) instances where a presumption that a hallucination was not purely subjective is afforded by peculiarities of dress or aspect in the figure presented ........... 426-431 § 7. And (3) instances where the phantasm appears at a time when the person whom it represents is, unknown to the percipient, actually approaching him, with thoughts more or less consciously turned in his direction 431-432 CHAPTER XV Further Auditory Cases Occurring to a Single Percipient § I. Cases where the phantasm has been of a recognised voice — the words heard having been, certainly in some cases and possibly in others, those which the distant agent was uttering ....... 433-436 § 2. Cases where what was heard was the percipient's own name — which is a very common form of purely subjective hallucination. In most of these cases there may probably have been a certain occupation of the agent's thoughts with the percipient ..... 436-439 § 3. Cases where the phantasm has been of an »«>'ecog'ni5f^ voice . 439-442 § 4. Cases where the impression was of a complete sentence, conveying either a piece of information or a direction, projected by the percipient as a message from without .......... 442-443 § 5. An example [omitted. — Ed.] where the sound heard was vocal, but not recognised and articulate ......... 443 § 6. Phantasms of non-vocal noises or shocks. These are parallel to the SYNOPSIS xxvii rudimentary visual hallucinations ; but need a more jealous scrutiny, since odd noises are often due to undiscovered physical causes in the vicinity. Still, some impressions of the sort are pretty clearly hallucinatory ; and the form is one which telepathic hallucinations seem occasionally to take. [Gurney's examples are omitted. — Ed.] ......... 443-444 CHAPTER XVI Tactile Cases and Cases Affecting More than One of the Percipient's Senses § I. Purely subjective impressions of touch, of at all a distinct kind, are rare ; and when they occur, may often be accounted for as illusions due to an involuntary muscular twitch. It is not surprising, therefore, that telepathic hallucinations of this type should be rare ...... 445 The most conclusive examples are those where an affection of touch is com- bined with one of sight or hearing. Examples .... 446-448 § 2. Combined affections of the senses of sight and hearing : one case (No. 299) is peculiar in that the person who was probably the agent was in the percipient's company at the time ....... 448-453 CHAPTER XVn Reciprocal Cases § I. It occasionally happens that at the time when A telepathically influ- ences B, A on his side has an impression which strongly suggests that B has reciprocally influenced him. The best proof of this is where A expresses in words some piece of knowledge as to B's condition. Other more doubtful cases (of which two are quoted) may be provisionally referred to the same type ; but unless A's description includes something which he could not have known or guessed in a normal manner, his alleged percipience of B cannot be assumed to have been more than mere subjective dream or vision . . . 454-458 § 2. Examples of apparently reciprocal action. They may be regarded as special cases of " telepathic clairvoyance " ; A's percipience of B being apparently active rather than passive, and due to some extension of his own faculties, con- nected with the abnormality of condition that occasions his agency, and not to any special abnormality in B's condition ..... 458-463 The cases which, on the evidence, would be clearly reciprocal, are so few in number as to justify a doubt whether they represent a genuine type. Supposing them to be genuine, however, their rarity is not hard to account for ; and it may be hoped that time will bring us more well-attested specimens . . . 465 CHAPTER XVIII Collective Cases § I. Phantasms which have affected the senses of more than one percipient, are a specially perplexing class. On the face of them, they suggest a real objective presence of the person seen or heard. But such " objectivity " (unless conceived as some illusive form of matter) can hardly be defined except just as a temporary existence in more minds than one : it does not explain, but merely repeats, the fact that the experience is collective ...... 466—467 In the absence of evidence (worthy of the name) that a telepathic phantasm has ever given a test of physical reality — e.g., by opening a door or a window — we are led to inquire how far the phenomena of collective hallucination can be covered by a theory of purely psychical impressions. Two views (which will subsequently prove capable of amalgamation) present themselves : — (1) that xxviii SYNOPSIS A, at a distance, produces sitnultaneous islepathic impressions on the minds of B and C, who happen to be together ; (2) that B's impression, however originated, passes on to C by a process of thought-transference — the hallucination itself being, so to speak, infectious ......... 467-468 § 2. The first of these hypotheses presents great difficulties. For our review of telepathic hallucinations, so far, has shown that they may take very various forms, and may be projected at various intervals of time (within a range of a few hours) from the crisis or event to which we trace them ; so that, supposing several persons to have been the joint recipients of a telepathic impression, it seems most improbable that they should independently invest it at the same moment with the same sensory form. Nor, again, should we expect to find, among those jointly affected, any person who was a stranger to the distant agent ; nevertheless, cases occur where such a person has shared in the collective percipience. And yet again, on this theory of independent affection of several persons, there seems no special reason why they should be in one another's company at the time, since the agent may presumably exercise his influence equally in any direction ; nevertheless, cases where the percipients have been apart are, in fact, extremely rare ....... 468-469 A few examples of the sort are given ; but in several even of these, the percipients, though not together, were very near one another, and had been to some extent sharing the same life ....... 469-473 § 3. As to the second of the proposed hypotheses — that one percipient catches the hallucination from another by a process of thought-transference — the question at once suggests itself whether such communicability is ever found in cases where no distant agent is concerned — cases of purely subjective hallucina- tion. Such an idea would, no doubt, be as new to scientific psychology as every other form of thought-transference ; but transient hallucinations of the sane have been so little studied or collected that it is not surprising if the evidence for collective experiences of the sort has escaped attention — though collective illusions have sometimes been described as hallucinations . . . 473-474 It is in collective cases that the importance of distinguishing illusions from hallucinations becomes plain. In illusions, the persons affected receive an actual sensory impression from a real object, the error being simply in their way of interpreting it ; and in the interpretation they are often greatly at the mercy of one another's suggestions. Many historical incidents — such as visions of signs in the heavens and of phantom champions — might be thus explained 474-476 In other alleged instances of " collective hallucination " there is no proof that the impression was really more than a vivid mental picture, evoked under excitement. And even where the image probably has been externahsed in space — as, e.g., in religious epidemics, or in experimentatiom with hypnotised subjects ■ — most cases may be at once explained, without any resort to thought-trans- ference, as due to a common idea or expectancy. (Apart, however, from special excitement or from hypnotism, the povv^er of mere verbal suggestion to produce delusions of the senses may easily be exaggerated) .... 476—478 It is only when these various conditions are absent — when the joint percept is clearly hallucination, and is also projected by the several percipients without emotional preparation or suggestion — that the hypothesis of thought-transference from one percipient to another can reasonably be entertained . . 478—479 § 4. The examples to be adduced, of collective hallucinations, not apparently originating in the condition of any absent living person, include cases which may be regarded by some as indicating post-mortem agency. It is not necessary to enter into the vexed question as to whether the power of exercising psychical energy can or cannot continue after physical death. Whatever answer that question received, these cases would still, in the writer's opinion (for reasons set forth in § 2), bear witness to a quite mundane transference between the minds of the living percipients ........ 479—481 § 5. FisMfl/ examples. Hallucinations of light .... .481 Various out-of-door experiences, not easy to explain as illusions . 481—484 Examples of the simultaneous appearance of an unrecognised figure to two percipients, who in most instances were in each other's company at the time. The two impressions received in several cases were not precisely similar, and in one (No. 322) were markedly different ...... 484-489 SYNOPSIS xxix Similar appearances of recognised phantasms ; one of which (case 333) represented the form of one of the percipients ..... 489-495 The auditory class requires special care, owing to the liability of real sounds (whose source is often uncertain) to be misinterpreted. Example . 495-496 The examples may at all events show that a purely psychical account of these joint experiences is possible. It is not, indeed, obvious why hallucinations of the senses should be a form of experience liable to transmission from mind to mind ; but as regards the cases which are telepathically originated, some explanation may perhaps be found in the fact that they at an}? rate involve a disturbance of a very peculiar kind ......... 496-497 § 6. Collective hallucinations of telepathic origin. Auditory examples, representing vocal sounds ........ 497-499 And non-vocal sounds ........ 499—502 Visual examples. In one of these (No. 345) the experiences of the two percipients were not precisely similar ...... 502-513 § 7. The fact that in most of the examples the two percipients, B and C, were together suggests that mere community of scene, or of immediate mental occupa- tion, may establish a rapport favourable to " psychical " transferences 513-514 And this conception may lead us, in cases where a distant agent, A, is con- cerned, to an amalgamation of the two hypotheses (see § i) which have hitherto been treated separately. C's experience, qua hallucination, that is to say in its sensory character, may be derived from B's ; but, for all that, A may be tele- pathically affecting C. It may be A's joint influence on B and C that has con- ditioned the transference of sensation between them ; or, in cases where C holds no intimate relation to A, a rapport may be established, ad hoc, between A and C by the rapport of both of them with B — who thus serves, so to speak, as a channel for C's percipience ; and this would even help to explain the cases where B is not himself consciously percipient ...... 514-515 The conception of rapport through community of mental occupation might explain the various cases where the telepathic influence seems to have been locally conditioned, by the presence of the percipient in a place that was interest- ing to the agent. And the idea may receive a still further extension in cases where there is reason to suppose a reciprocal telepathic clairvoyance of the scene on the agent's part .......... 515-516 Conjectures of this sort concerning the more outlying telepathic phenomena have an air of rashness ; but the mere fact that " psychical " transferences are possible, when once admitted, opens up a scheme of Idealism within whose bounds (if bounds there be) the potential unity between individual minds is at any rate likely to reaUse itself in surprising ways .... 516-517 CONCLUSION § I. The case for spontaneous telepathy, being essentially a cumulative one, hardly admits of being recapitulated in a brief and attractive form. Nothing but a detailed study of the evidence — dull as that study is — can justify definite conclusions concerning it. After all, the dulness is perhaps not greater than attaches to the mastery of details in other departments of knowledge ; and it cannot be too clearly realised that what the research requires is not sensational incidents, but verified dates ........ 518-519 § 2. The present instalment of evidence, with all its defects, may j^et, by making the idea of telepathy better understood, facilitate collection in the future ; and already various difficulties and prejudices show signs of giving way 519-520 § 3. But though a fair field is sure, in time, to be allowed to the work, its advance must depend on very wide co-operation ; and the more so as the several items of proof tend to lose their effect as they recede into the past. The experi- mental investigations must be greatly extended, the spontaneous phenomena must be far more intelligently watched for and recorded, before the place of telepathy in scientific psychology can be absolutely assured . . . 520 LIST OF NUMBERED CASES, TRANSITIONAL AND SPONTANEOUS, INCLUDED IN THIS EDITION Name of Agent, Percipient, or a No. Witness Name of Agent, Percipient, or a Page No. Witness Page • 71 65 Dyne 188 . 72 70 Reay 191 • 73 73 " England " 193 • 73 74 M.

The subject of this book is one which a brief title is hardly sufficient to explain. For under our heading of " Phantasms of the Living," we propose, in fact, to deal with all classes of cases where there is reason to suppose that the mind of one human being has affected the mind of another, without speech uttered, or word written, or sign made ; — ^has affected it, that is to say, by other means than through the recognised channels of sense. To such transmission of thoughts or feelings we have elsewhere given the nam.e of telepathy ; and the records of an experimental proof of the reality of telepathy will form a part of the present work. But, for reasons which will be made manifest as we proceed, we have included among telepathic phenomena a vast class of cases which seem at first sight to involve something widely different from a mere transference of thought. I refer to apparitions ; excluding, indeed, the alleged apparitions of the dead, but including the apparitions of all persons who are still living, as we know life, though they may be on the very brink and border of physical dissolution. And these apparitions, as will be seen, are them- selves extremely various in character ; including not visual phenomena alone, but auditory, tactile, or even purely ideational and emotional impressions. All these we have included under the term phantasm ; a word which, though etymologically a mere variant of phantom, has been less often used, and has not become so closely identified with visual im- pressions alone. Such, then, is the meaning of our title ; but something more of explana- tion is necessary before the tone and purport of the book can be correctly apprehended. In a region so novel we could hardly be surprised at any amount of misinterpretation. Some readers, for instance, may fancy that a bulky and methodical treatise on phantoms can be but a half- serious thing. Others may suspect that its inspiration is in the love of paradox, and that a fantastic craving for originality has led the authors along a path where they cannot expect, and can hardly desire, that the sober world should follow them. § 2. It is necessary, therefore, to state at once that we have no wish either to mystify or to startle mankind. On the contrary, the conjoint xxxiv INTRODUCTION and consultative scheme according to which this book has been com- piled is thus arranged mainly with a view to correcting or neutralising individual fancies or exaggerations, of leaving as little as possible to the unchecked idiosyncrasy of any single thinker. And, again, we wish distinctly to say that so far from aiming at any paradoxical reversion of established scientific conclusions, we conceive ourselves to be working (however imperfectly) in the main track of discovery, and assailing a problem which, though strange and hard, does yet stand next in order among the new adventures on which Science must needs set forth, if her methods and her temper are to guide and control the widening curiosity, the expanding capacities of men. We anticipate, in short, that although it may at first be said of us that we have performed with needless elaboration a foolish and futile task, the ultimate verdict on our work will rather be that we have under- taken — with all too limited a knowledge and capacity — to open an inquiry which was manifestly impending, and to lay the foundation-stone of a study which will loom large in the approaching age. Our only paradox, then, is the assertion that we are not paradoxical ; and that assertion it is the main business of this Introduction to justify, § 3. For this purpose two principal heads of exposition will be required. In the first place, since this book (for whose contents we are solely re- sponsible) was undertaken by us at the request of the Council of the Society for Psychical Research, and is largely based on material v/hich that Council has placed at our disposal, it will be necessary to say some- thing as to the scope and object of the Society in question ; — its grounds for claiming a valid scientific position, and its points of interconnection with established branches of philosophic inquiry. And, secondly, it will be needful to indicate the precise position which the theme of this book occupies in the field of our investigations ; the reason why we have isolated these special phenomena in a separate group, and have selected them for discussion at this early stage of the Society's labours. A reader of the programme of the Society will probably feel that although the special topics to which attention is there invited may be unfamiliar, yet its general plea is such as he has often noted in the history of science before. " To approach these various problems without pre- judice or prepossession of any kind, and in the same spirit of exact and unimpassioned inquiry which has enabled Science to solve so many problems, once not less obscure nor less hoth'' debated " ; — phrases like these have no more of novelty than there might be, for instance, in the proposal of a Finance Minister to abolish the last of a long series of protective embargoes. Free Trade and free inquiry have each of them advanced step by step, and by dint of the frequent repetition, under varying difficulties, of very similar, and very elementary, truths. The special peculiarity of our topic is that it is an article (so to say) on which the Free Traders themselves have imposed an additional duty ; that it has been more sternly discountenanced by the men who appeal to experi- ment than by the men who appeal to authority ; — that its dispassionate discussion has since the rise of modern science been tabooed more jealously INTRODUCTION xxxv than when the whole province was ciaimed by theology alone. There have been reasons, no doubt, for such an exclusion ; and I am not assert- ing that either Free Trade or free inquiry is always and under all circum- stances to be desired. But it is needful to point out yet once more how plausible the reasons for discouraging some novel research have often seemed to be, while yet the advance of knowledge has rapidly shown the futility and folly of such discouragement. It was the Father of Science himself who was the first to circum- scribe her activity. Socrates, in whose mind the idea of the gulf between knowledge and mere opinion attained a dominant intensity which impressed itself on all ages after him, — Socrates expressly excluded from the range of exact inquiry all such matters as the movements and nature of the sun and moon. He wished — and as he expressed his wish it seemed to have all the cogency of absolute v/isdom — that men's minds should be turned to the ethical and political problems v.'hich truly concerned them, — not wasted in speculation on things unknowable — things useless even could they be known. In a kindred spirit, though separated from Socrates by the whole result of that physical science which Socrates had deprecated, we find a great modern systematiser of human thought again endeavouring to direct the scientific impulse towa.rds things serviceable to man ; to divert it from things remote, unknowable, and useless if known. What, then, in Comte's view, are in fact the limits of mean's actual home and business ? the bounds within which he may set himself to learn all he can, assured that all will serve to inform his conscience and guide his life ? It is the solar system vvdiich has become for the French philosopher v.'hat the street and market-place of Athens were for the Greek. And this enlargement (it need hardly be said) is not due to any wider grasp of mind in Comte than in Socrates, but simply to the march of science ; which has shown us that the whole solar system does, in fact, minister to our practical needs, and that the Nautical Almanack demands for its construction a mapping of the paths of those ordered luminaries which in the time of Socrates seemed the very wanderers of Heaven. I need not say that Comte's prohibition has been altogether neglected. No frontier of scientific demarcation has been established between Neptune and Sirius, between Uranus and Aldebaran. Our knowledge of the fixed stars increases yearly ; and it would be rash to maintain that human conduct is not already influenced by the conception thus gained of the unity and immensity of the heavens. To many of the comments that have been made on our work, even by men who are not formal Comtists, the above reflections furnish a fitting reply. But it is not only, nor perhaps mainly, on account of the remote- ness of our subject, or its unimportance to human progress, that objec- tion is taken to our inquiry. The criticisms which have met us, from the side sometimes of scientific, sometimes of religious orthodox}^ have em- bodied, in modernised phraseology, nearly every well-worn form of timid protest, or obscurantist demurrer, with which the historians of science have been accustomed to give piquancy to their long tale of discovery and achievement. It would have been convenient had these objections been presented to us in a connected and formal manner. But this has xxxvi INTRODUCTION not been the case ; and, in fact, they are in their very nature too incoherent, too self-contradictory, for continuous statement. Sometimes we are told that we are inviting the old theological spirit to encroach once more on the domain of science ; sometimes that we are endeavouring to lay the impious hands of Science upon the mysteries of Religion. Sometimes we are informed that competent savants have already fully explored the field which we propose for our investigation ; sometimes that no respectable man of science would condescend to meddle Avith such a reeking mass of fraud and hysteria. Sometimes we are pitied as laborious triflers who prove some infinitely small matter with mighty trouble and pains ; sometimes we are derided as attempting the solution of gigantic problems by slight and superficial means. § 4. The best way of meeting objections thus confused and contra- dictory will be to show as clearly as we can at what points our inquiries touch the recent results of science ; what signs there are which indicate the need of vigorous advance along the lines which we have chosen. We shall show, perhaps, that there is a kind of convergence towards this especial need — that in several directions of research there is felt that kind of pause and hesitancy which is wont to precede the dawn of illumin- ating conceptions. We shall not, of course, thus prove that our own attempt has been successful, but we shall prove that it was justified ; that if the problems which we set ourselves to solve are found to be insoluble, the gaps thus left in the system of thought on which man's normal life is based will be such as can neither be ignored nor supplied, but will become increasingly palpable and increasingly dangerous. Let us consider how far this remark can be justified with regard to some of the leading branches of human knowledge in turn. And let us take first Biology, the science which on the whole approaches the closest to our own inquiries. Biology has, during the last half-century, made an advance which, measured by the hold exercised on the mass of culti- vated minds, has perhaps had no parallel since the forward stride of astro- nomy and physics in the days of Newton. A glance at the text-books of the last generation, in physical or mental science — ^Whewell's History of the Inductive Sciences, or Mill's Logic, — as compared, for instance, with the works of their immediate successor, Mr. Herbert Spencer, shows something which is not so much progress as revolution — the transforma- tion of Biology from a mere special department of knowledge into the key to man's remotest history, the only valid answer to the profoundest questions as to his present being. For, in truth, it is Biology above all other sciences which has profited by the doctrine of evolution. In evolution, — in the doctrine that the whole cosmical order is the outcome of a gradual development, — mankind have gained for the first time a working hypothesis which covers enough of the known facts of the universe to make its possible extension to all facts a matter of hopeful interest. And Biology, which even at the date of Whewell's book could barely make good its claim to be regarded as a coherent science at all, has now acquired a co-ordinating and continuous principle of unity which renders it in some respects the best t3'^pe of a true science which we possess, It traces life from the protozoon to the INTRODUCTION xxxvii animal, from the brute to the man ; it offers to explain the complex fabric of human thought and emotion, viewed from the physical side, as the development of the molecular movements of scarcely-differentiated fragments of protoplasm. And along with this increased knowledge of the processes by which man has been upbuilt has come also an increased knowledge of the pro- cesses which are now going on within him. The same inquiries which have brought our organic life into intelligible relation with the whole range of animal and vegetable existence have enabled us also to conceive more definitely the neural side of our mental processes, and the relation of cerebral phenomena to their accompanying emotion or thought. And hence, in the view of some ardent physiologists, it is becoming more and more probable that we are in fact physiological automata ; that our consciousness is a mere superadded phenomenon — a mere concomitant of some special intensity of cerebral action, with no basis beyond or apart from the molecular commotion of the brain. But this view, as it would seem, depends in a great part upon some- thing which corresponds in the mental field to a familiar optical illusion. When we see half of some body strongly illuminated, and half of it feebly illuminated, it is hard to believe that the brilliant moiety is not the larger of the two. And, similarly, it is the increased definiteness of our con- ception of the physical side of our mental operations which seems to in- crease its relative importance, — to give it a kind of priority over the psychical aspect of the same processes. Yet, of course, to the philosophic eye the central problem of the relation of the objective and subjective sides of these psycho-neural phenomena can be in no way altered by any increase of definiteness in our knowledge of the objective processes which correspond to the subjective states. And, on the other hand, there is one singular logical corollary which seems thus far to have escaped the notice of physiologist and psychologist alike. It is this : that our increased vividness of conception of the physical side of mental life, while it cannot possibly disprove the independence of the psychical side, may quite conceivably prove it. I will again resort to the (very imperfect) analogy of a partially illuminated body. Suppose that one hemisphere of a globe is strongly lit up, and that the other is lit up by faint and scattered rays.^ I am trying to discern whether the two hemispheres are symmetrically marked throughout. Now no clearness of marks on the bright hemisphere can disprove the existence of corre- sponding marks on the dim one. But, on the other hand, it is conceivable that one of the few rays which fall on the dim hemisphere may reveal some singular mark which I can see that the bright hemisphere does not possess. And the brighter the bright hemisphere is made, the more certain do I become that this particular mark is not to be found on it. § 5. I will give two concrete examples of what I mean — one of them drawn from the conclusions of a great physiologist, the other from the ^ The analogy will be closer if we suppose that the second half is lit, not dimly but from within, — since in one sense consciousness gives us more information as to the psychical than as to the physical side of life, though it is information of a different qualili/. xxxviii INTRODUCTION obvious condition of a new branch of experimental inquiry. I shall not discuss either instance in detail, since I am here only endeavouring to show that with increased precision in psycho-physical researches the old problems of free-will, soul and body, etc., are presenting more definite issues, and offering a far more hopeful field to the exact philosopher than their former vagueness allowed. My first illustration, then, is from the form which the old free-will controversy has assumed in the hands of Wundt. Wundt stands, of course, among the foremost of those who have treated human thought and sensation as definite and measurable things, who have computed their rate of transit, and analysed their elements, and enounced the laws of their association. It is not from him that we need look for any lofty metaphysical view as to the infinite resources of spiritual power, — the transcendental character of psychical phenomena. But, nevertheless, Wundt believes himself able to assert that there is within us a residue — an all-important residue — of psychical action which is incommensurable with physiological law. So far, he holds, is the principle of conservation of energy from covering the psychical realm, that the facts of mental evolution proclaim that the very contrary is the case ; — and that what really obtains is rather " an unlimited new creation of psychical energy."^ Nay, so convinced is he of the inadequacy of any system of physiological determinism to explain psychical facts, that he holds that we must directly reverse the materialistic view of the relation of the corporeal to the psychical life. " It is not the psychical life," he says, " which is a product of the physical organisation ; rather it is the physical organism which, in all those purposive adjustments which distinguish it from inorganic com- pounds, is itself a psychical creation." ^ I am not here expressing either agreement or disagreement with this general view. I am merely pointing out that here is an opinion which, whether right or wrong, is formed as a result not of vagueness but of distinctness of physiological conceptions. And my illustration shows at any rate that the development of physiology is tending not always to make the old psychical problems seem meaningless or sterile, but rather to give them actuality and urgency, and even to suggest new possibilities of their solution. § 6. But, to come to my second instance, it is perhaps from the present position of hypnotism that the strongest argument may be drawn for the need of such researches as ours, to supplement and co-ordinate the some- what narrower explorations of technical physiology. For the actual interest of the mesmeric or hypnotic trance — I am not now dealing with the rival theories which these words connote — the central interest, let us say, of induced somnambulism, or the sleep-waking state — has hardly as yet revealed itself to any section of inquirers. ^ " Hier gilt vielmehr ein Gesetz unbegrenzter Neuschopfung geistiger Energie, welches nur dutch die sinnliche Bestimmtheit des geistigen Lebens gewisse Hemmungen erleidet." — Wundt, Logik, ii., p. 507. - " Nicht das geistige Leben ist era Erzeugniss der physischen Organisation, sondern diese ist in allem, was sie an zweckvoUen Einrichtungen der Selbstregulirung und der Energie-verwerthung vor den Substanzcomplexen der unorganischen Natur voraushat, eine geistige Schopfung." — Wundt, Logik, ii., p. 471. INTRODUCTION xxxix That interest lies neither in mesmerism as a curative agency, as EUiotson would have told us, nor in hypnotism as an illustration of in- hibitory cerebral action, as Heidenhain would tell us now. It lies in the fact that here is a psychical experiment on a larger scale than was ever possible before ; that we have at length got hold of a handle which turns the mechanism of our being ; that we have found a mode of shifting the threshold of consciousness which is a dislocation as violent as madness, a submergence as pervasive as sleep, and yet is waking sanity ; that we have induced a change of personality which is not per se either evolutive or dissolutive, but seems a mere allotropic modification of the very ele- ments of man. The prime value of the hypnotic trance lies not in what it inhibits, but in what it -reveals ; not in the occlusion of the avenues of peripheral stimulus, but in the emergence of unnoted sensibilities, nay, perhaps even in the manifestation of new and centrally initiated powers. The hypnotic trance is an eclipse of the normal consciousness which can be repeated at will. Now the first observers of eclipses of the sun ascribe them to supernatural causes, and attribute to them an occult influence for good or evil. Then comes the stage at which men note their efiects on the animal organism, the roosting of birds, the restlessness of cattle. Then come observations on the intensity of the darkness, the aspect of the lurid shade. But to the modern astronomer all this is trifling as compared with the knowledge which those brief moments give him of the orb itself in its obscuration. He learns from that transient darkness more than the noon of day can tell ; he sees the luminary no longer as a defined and solid ball, but as the centre of the outrush of flaming energies, the focus of an effluence Vv^hich coruscates untraceably through immeasurable fields of heaven. There is more in this parallel than a mere empty metaphor. It sug- gests one of the primary objects which psychical experiment must seek to attain. Physical experiment aims at correcting the deliverances of man's consciousness with regard to the external world by instruments which extend the range, and concentrate the power, and compensate the fallacies of his senses. And similarly, oiir object must be to correct the deliverances of man's consciousness concerning the processes which are taking place within him by means of artificial displacements of the psycho- physical threshold ; by inhibiting normal perception, obliterating normal memory, so that in this temporary freedom from preoccupation by accus- tomed stimuli his mind may reveal those latent and delicate capacities of which his ordinary conscious self is unaware. § 7. It was thus, in fact, that thought-transference, or telepathy, was first discovered. In the form of community of sensation between operator and subject, it was noted nearly a century ago as a phenomenon incident to the mesmeric trance. Its full importance was not perceived, and priceless opportunities of experiment were almost wholly neglected. In order to bring out the value and extent of the phenomenon it was necessary, we venture to think, that it should be investigated by men whose interest in the matter lay not in the direction of practical thera- peutics but of psychical theory, and who were willing to seek and " test xl INTRODUCTION for it " under a wide range of conditions, not in sleep-waking life only, but in normal waking, and normal sleep, and, as this book will indicate, up to the very hour of death. The difficulties of this pursuit are not physiological only. But, never- theless, in our endeavours to establish and to elucidate telepathy, we look primarily for aid to the most recent group of physiological inquirers, to the psycho-physicists whose special work — as yet in its infancy — has only in our own day been rendered possible by the increased accuracy and grasp of experimental methods in the sciences which deal with Life. The list of Corresponding Members of our Society will serve to show that this confidence on our part is not wholly unfounded, and to indicate that we are not alone in maintaining that whatever may be the view of these perplexing problems which ultimately prevails, the recent advances of physiology constitute in themselves a strong reason — not, as some hold, for the abandonment of all discussion of the old enigmas, but rather for their fresh discussion with scientific orderliness, and in the illumination of our modern day. § 8. From Biology we may pass, by an easy transition, to what is commonly known as Anthropology, — the comparative study of the different races of men in respect either of their physical characteristics, or of the early rudiments of what afterwards develops into civilisation. The connection of anthropology with psychical research will be evident to any reader who has acquainted himself with recent expositions of Primitive Man. He may think, indeed, that the connection is too evident, and that we can hardly bring it into notice without proving a good deal more than we desire. For as the creeds and customs of savage races become better known, the part played by sorcery, divination, apparitions becomes increasingly predominant. Mr. Tylor and Sir John Lubbock have made this abundantly clear, and Mr. Spencer has gone so far as to trace all early religion to a fear of the ghosts of the dead. In the works of these and similar authors, I need hardly say, we are led to regard all these beliefs and tendencies as due solely to the childishness of savage man — as absurdities which real progress in civilisation must render increasingly alien to the developed common-sense, the rational experi- ence of humanity. Yet it appears to me that as we trace the process of evolution from savage to civilised man, we come to a point at which the inadequacy of this explanation is strongly forced on our attention. Certainly this was my own case when I undertook some years ago to give a sketch of the Greek oracles. It soon became evident to me that the mass of phenomena included under this title had, at any rate, a psycho- physical importance which the existing works on the subject for the most part ignored. I scarcely ventured myself to do more than indicate where the real nodi of the inquiry lay. But when a massive treatise on Ancient Divination appeared from the learned pen of M. Bouch6-Leclercq, I looked eagerly to see whether his erudition had enabled him to place these problems in a new light. I found, however, that he explicitly renounced all attempt to deal with the phenomena in more than a merely external way. He would record, but he would make no endeavour to explain ; — taking for granted, as it appeared, that the explanation de- INTRODUCTION xli pended on fraud alone, and on fraud whose details it would now be im- possible to discover. I cannot think that such a view can any longer satisfy persons ade- quately acquainted with the facts of hypnotism. Whatever else, whether of fraud or reality, there may have been on the banks of Cassotis or Castaly, — unde superstitiosa primmn sacra evasit vox f era, — there were at least the hypnotic trance and hystero-epilepsy. And until these and similar elements can be sifted out of the records left to us, with something of insight gained by familiarity with their modern forms, our knowledge of Pythia or of Sibyl will be shallow indeed. Still more markedly is such insight and experience needed in anthro- pology proper — in the actual observation of the savage peoples who still exist. It is to be hoped that shamans and medicine-men will not vanish before the missionary until the}^ have yielded some fuller lessons to the psycho-physicist — until the annals of the Salpetriere and the experi- ments of Dean's Yard^ have been invoked in explanation of the weird terrors of the Yenisei and the Congo. § 9. Passing on from Anthropology to history in its wider accepta- tion, we find these psycho -physical problems perpetually recurring, and forming a disturbing element in any theory of social or religious evolution. The contagious enthusiasms of the Middle Ages — the strange endemic maladies of witchcraft, vampirism, lycanthropy — even the individual inspiration of a Mahomet or a Joan of Arc — these are phenomena which the professed historian feels obliged to leave to the physician and the alienist, and for which the physician and the alienist, in their turn, have seldom a satisfactory explanation. Nor do phenomena of this kind cease to appear with the advance of civilisation. In detailed modern histories, in the biographies of eminent men, we still come upon incidents which are, at any rate at first sight, of a supernormal^ kind, and over which the narrator is forced to pass with vague or inadequate comment. But it is, of course, in dealing with the history of religions that our lack of any complete grasp of psychical phenomena is most profoundly felt. And here, also, it is as a result of recent progress, — of the growth of the comparative study of religions, — that we are able to disengage, ^ [The then office of the Society for Psychical Research. — Ed.] " " I have ventured to coin the word ' supernormal ' to be applied to phenomena which are beyond xoliat usually happens — beyond, that is, in the sense of suggesting unknown psychical laws. It is thus formed on the analogy of abnormal. When we speak of an abnormal phenomenon we do not mean one which contravenes natural laws, but one which exhibits them in an unusual or inexplicable form. Similarly by a supernormal phenomenon, I mean, not one which overrides natural laws, for I believe no such phenomenon to exist, but one which exhibits the action of laws higher, in a psychical aspect, than are discerned in action in cvery-day life. By higher (either in a psychical or in a physiological sense), I mean ' apparently belong- ing to a more advanced stage of evolution.' " — Proceedings of the S.P.R., vol. iti. p. 30. Throughout this treatise we naturally need a designation for phenomena which are inexplicable by recognised physiological laws, and belong to the general group into the nature of which we are inquiring. The term psychical (which is liable to misapprehension even in the title of our Society) can hardly be used without apology in this specialised sense.- The occasional introduction of the word super- normal may perhaps be excused. xlii INTRODUCTION in a generalised form, the chief problems with which our " psychical " science, if such could be established, would be imperatively called on to deal. For we find throughout the world's history a series of great events which, though differing widely in detail, have a certain general resemblance both to each other and to some of those incidents both of savage and of ordinary civilised life to which reference has already been made. The elements which are common to the great majority of religions seem to be mainly two — namely, the promulgation of some doctrine which the religious reformer claims to have received, or actually to communicate, in some supernormal manner ; and the report of a concurrent manifesta- tion of phenomena apparently inexplicable by ordinary laws. Now, with the rise of one religion our Society has already had practi- cally to deal. Acting through Mr. Hodgson, whose experiences in the matter have been elsewhere detailed,^ a committee of the Society for Psychical Research has investigated the claim of the so-called " Theos- ophy," of which Madame Blavatsky was the prophetess, to be an incipient world-religion, corroborated by miraculous, or at least supernormal, phenomena, — and has arrived at the conclusion that it is merely a rechaujfe of ancient philosophies, decked in novel language, and supported by ingenious fraud. Had this fraud not been detected and exposed, and had the system of belief supported thereon thriven and spread, we should have witnessed what the sceptic might have cied as a typical case of the origin of religions. A Gibbon of our own cay, reviewing the different motives and tendencies which prompt, or spread, revelations, might have pointed to Theosophy and Mormonism as covering between them the whole ground ; — from the adroit advantage taken of mystical aspiration in the one religion, to the commonplace action of greed and lust upon helplessness and stupidity which forms the basis of the other. But if it should be argued from these analogies that in no case of the foundation of a religion would any scientific method of psychical inquiry prove necessary or fruitful, if we knew all the facts ; but that such develop- ments might be sufficiently dealt with by ordinary common-sense, or, like Mormonism, by the criminal law, the generalisation would be hasty and premature. We need not go far back to discover two religions whose central fact is not a fact of fraud at all, but an unexplained psychical phenomenon. I allude to the vision-life of Sweden borg, and the speaking with tongues which occurred in the church of Irving, — each of which constitutes a central point of faith for a certain number of intelligent and educated persons at the present day. Of neither of these facts can Science at present offer a satisfactory explanation. The speaking with tongues seems plainly to have been for the most part (though not entirely) a genuine automatic phenomenon. But as to the origin of such automatic utterances (conveyed in speech or writing), as to the range from which their contents are drawn, or the kind of attention which they can claim, there is little or nothing to be learnt from accepted textbooks. We ai"e groping among the first experiments, the simplest instances, on which any valid theory can be based. ^ ^ Proceedings of the S.P.R., vol. ill. * See papers on "Automatic Writing" in Proceedings of the S.P.R., vols.ii. and iii. INfRODUCTiON xiiii The case of Swedenborg carries us still further beyond the limits of our assured knowledge. Of madness and its delusions, indeed, we know much ; but it would be a mere abuse of language to call Swedenborg mad. His position must be decided by a much more difficult analogy. For before we can even begin to criticise his celestial visions we must be able in some degree to judge of his visions of things terrestrial ; we must face, that is to say, the whole problem of so-called clairvoyance, of a faculty which claims to be not merely receptive but active, — a projection of super- sensory percipience among scenes distant and things unknown. And the existence of such a faculty as this will assuredly never be proved by a mere study of the transcendental dicta of any single seer. This problem, too, must be approached, partly through the hypnotic trance, in which the best-attested instances of clairvoyance are alleged to have occurred, and partly through the collection of such supernormal narratives as some of those which find place in the present book. Even a sketch like this may indicate how complex and various may be the problems which underlie that " History of Sects " in which a Bossuet might see only the heaven-sent penalty for apostasy against the Church, — a Gibbon, the mere diverting panorama of the ever-varying follies of men. § 10. But reflections like these lie on the outskirts of a still larger and graver question. What (it is naturally asked) is the relation of our study — not to eccentric or outlying forms of religious creed — but to central and vital conceptions ; and especially to that main system of belief to which in English-speaking countries the name of religion is by popular usage almost confined ? Up till this time those vt'ho have written on behalf of the Society for Psychical Research have studiously refrained from entering on this im- portant question. Our reason for this reticence is obvious enough when stated, but it has not been universally discerned. We wished to avoid even the semblance of attracting the public to our researches by any allurement which lay outside the scientific field. We could not take for granted that our inquiries would make for the spiritual view of things, that they would tend to establish even the independent existence, still less the immortality, of the soul. We shrank from taking advantage of men's hopes or fears, from representing ourselves as bent on rescuing them from the materialism which forms so large a factor in modern thought, or from the pessimism which dogs its steps with unceasing persistency. We held it to be incumbent on us, in an especial degree, to maintain a neutral and expectant attitude, and to conduct our inquiries in the " dry light " of a dispassionate search for truth. And this position we still maintain. This book, as will be seen, does not attempt to deal with the most exciting and popular topics which are included in our Society's general scheme. And we shall be careful in the pages that follow to keep within our self-assigned limits, and to say little as to any light which our collected evidence may throw on the possibility of an existence continued after our physical death. That master-problem of human life must be assailed by more deliber- ate approaches, nor must we gild our solid arguments with the radiance of an unproved surmise. But it would, nevertheless, be impossible, in a xliv INTRODUCTION discussion of this general kind, to pass over the relation of psychical research to religion altogether in silence. And, indeed, since our inquiries began, the situation has thus far changed that we have now not anticipa- tion merely, but a certain amount of actual achievement, to which to appeal. We hold that we have proved by direct experiment, and corrobor- ated by the narratives contained in this book, the possibility of communica- tions between two minds, inexplicable by any recognised physical laws, but capable (under certain rare spontaneous conditions) of taking place when the persons concerned are at an indefinite distance from each other. And we claim further that by investigations of the higher phenomena of mesmerism, and of the automatic action of the mind, we have confirmed and expanded this view in various directions, and attained a standing- point from which certain even stranger alleged phenomena begin to assume an intelligible aspect, and to suggest further discoveries to come. Thus far the authors of this book, and also the main group of their fellow-workers, are substantially agreed. But their agreement as to the facts actually proved does not extend — it is not even to be desired that it should extend — to the speculations which in one direction or another such facts must inevitably suggest. They are facts which go too deep to find in any two minds a precisely similar lodgment, or to adjust them- selves in the same way to the complex of pre-existent conceptions. The following paragraphs, therefore, must be taken merely as reflecting the opinions provisionally held by a single inquirer. I may say, then, at once that I consider it improbable that telepathy will ever receive a purely physical explanation, — an explanation, that is to say, wholly referable to the properties of matter, as molecular matter is at present known to us. I admit, of course, that such an explanation is logically conceivable ; that we can imagine that undulations should be propagated, or particles emitted, from one living organism to another, which should excite the percipient organism in a great variety of ways. But it seems to me, — and I imagine that in this view at any rate the majority of Materialists will concur, — that if the narratives in this book are to be taken as, on the whole, trustworthy, the physical analogies are too faint, and the physical difficulties too serious, to allow of our intruding among the forces of material Nature a force which — unlike any other — would seem (in some cases at least) neither to be diminished by any distance nor to be impeded by any obstacle whatsoever. I lay aside, for the purposes of the present argument, the possibility of a monistic scheme of the universe, — of a conseniiens conspirans continuata cognatio rerum which may present in an unbroken sequence both what we know as Matter and what we know as Mind. Such a view, — though to higher intelligences it may perhaps be an intuitive certainty, — can for us be nothing more than a philosophic opinion. Our scientific arguments must needs be based on the dualism which our intellects, as at present constituted, are in fact unable to transcend. I maintain, therefore, that if the general fact of telepathic communica- tion between mind and mind be admitted, it must also be admitted that an element is thus introduced into our conception of the aggregate of empirically known facts which constitutes a serious obstacle to the material- istic synthesis of human experience. The psychical element in man, I INTRODUCTION xlv repeat, must henceforth almost inevitably be conceived as having relations which cannot be expressed in terms of matter. Now this dogma, though wholly new to experimental science, is, of course, familiar and central in all the higher forms of religions. Relations inexpressible in terms of matter, and subsisting between spirit and Spirit, — the human and the Divine, — are implied in the very notion of the interchange of sacred love and love, of grace and worship. I need hardly add that the reality of any such communion is rigidly excluded by the materialistic view. The Materialist, indeed, may regard prayer and aspira- tion with indulgence, or even with approval, but he must necessarily conceive them as forming merely the psychical side of certain molecular movements of the particles of human organisms, and he must necessarily regard the notion of Divine response to prayer as an illusion generated by subsequent molecular movements of the same organisms, — the mere recoil and reflux of the wave which the worshipper himself has created. It would, of course, be mere offensive presumption to draw a parallel between our telepathic experiments and such a relation between a human and Divine spirit as the devout soul believes itself to realise in prayer. One side of that communion must ex hypothesi transcend the measurement or analysis of finite minds. But, confining our view wholly to the part played by the human organism, it seems to me incontestable that our experiments suggest possibilities of influence, modes of operation, which throw an entirely fresh light on this ancient controversy between Science and Faith. I claim at least that any presumption which science had established against the possibility of spiritual communion is now re- butted ; and that inasmuch as it can no longer be afflrmed that our minds are closed to all influences save such as reach them through sensory avenues, the Materialist must admit that it is no longer an unsupported dream but a serious scientific possibility, that if any intelligences do in fact exist other than those of living men, influences from those intelligences may be con- veyed to our own mind, and may either remain below the threshold of consciousness, or rise into definite consciousness, according as the presence or absence of competing stimuli, or other causes as yet unknown to us, may determine. §11.1 shall leave this proposition expressed thus in its most abstract and general form. And I may add — it is a reflection which I must ask the reader to keep steadily in mind, — that any support or illumination which religious creeds may gain from psychical inquiry is likely to aflect not their clauses but their preamble ; is likely to come, not as a sudden discovery bearing directly on some specific dogma, but as the gradual discernment of laws which may fundamentally modify the attitude of thoughtful minds. Now, in what I have called the preamble of all revelations two theses are generally involved, quite apart from the subject-matter, or the Divine sanction, of the revelation itself. We have to assume, first, that human testim.ony to supernorinal facts may be trustworthy ; and secondly, that there is something in the nature of man which is capable of responding to — I may say of participating in — these supernormal occurrences. That is to say, revelations are not proved merely by large external facts, per- xlvi INTRODUCTION ceptible to every one who possesses the ordinary senses, nor again are they proved solely by what are avowedly mere subjective impressions, but they are largely supported by a class of phenomena which comes between these two extremes ; by powers inherent in certain individuals of beholding spiritual visions or personages unseen by common eyes, of receiving information or guidance by interior channels, of uttering truths not consciously acquired, of healing sick persons by the imposition of hands, with other faculties of a similarly supernormal kind. And I hope that I shall not be thought presumptuous or irreverent if (while carefully abstaining from direct comment on any Revelation) I indicate what, in my view, would be the inevitable effect on the attitude of purely scientific minds towards these preliminary theses, — this pre- amble, as I have said, of definite religions, — were the continued prosecu- tion of our inquiry to lead us after all to entirely negative conclusions, were all our evidence to prove untrustworthy, and all our experiments unsound. For in the first place it is plain that this new science of which we are endeavouring to lay the foundations stands towards religion in a very different position from that occupied by the rising sciences, such as geology or biology, whose conflict or agreement with natural or revealed religion has furnished matter for so much debate. The discoveries of those sciences can scarcely in themselves add support to a doctrine of man's soul and immortality, though they may conceivably come into collision with particular forms which that doctrine has assumed. Religion, in short, may be able to assimilate them, but it would in no way have suffered had they proved altogether abortive. But with our study the case is very different. For, to take the firs of the two preliminary theses of religion already referred to, the question whether human evidence as to supernormal occurrences can ever be trusted has been raised by our inquiries in a much more crucial form than when Hume and Paley debated it with reference to historical incidents only. We discuss it with reference to alleged contemporary incidents ; we en- deavour to evaluate by actual inspection and cross-examination the part which is played in supernormal narratives by the mere love of wonder, " the mythopceic faculty," the habitual negligence and ignorance of mankind. And if all the evidence offered to us should crumble away on exact investigation — as, for instance, the loudly vaunted evidence for the marvels connected with Theosophy has crumbled — it will no doubt be questioned whether the narratives on which the historic religions depend for their acceptance could have stood the test of a contemporaneous inquiry of a similarly searching kind. And more than this, it will not only be maintained that the collapse of our modern evidence to supernormal phenomena discredits all earlier records of the same kind by showing the ease with which such marvels are feigned or imagined, but also that it further discredits those records by making them even more antecedently improbable than they were before. Not only will it be said that the proved fallibility of the modern witnesses illustrates the probable fallibility of the ancient ones, but the failure of the inquiry to elicit any indication that supernormal faculties do now exist in man will fro tanio throw a retrospective improbability on the INTRODUCTION xlvii second of the prelimir.ary theses of rehgion, which assumes that some such supernormal faculty did at any rate exist in man at a given epoch. It may indeed be urged that such faculties were given for a time, and for a purpose, and were then withdrawn. But the instinct of scientific continuity, which even in the shaping of the solid continents is fain to substitute for deluge and cataclysm the tideway and the ripple and the rain, will rebel against the hypothesis of a b^^gone age of inward miracles, — a catastrophic interference with the intimate nature of man. I will illustrate my meaning by a concrete example, which does not involve any actual article of Protestant faith. The ecstasy and the stigmata of St. Francis are an important element in Roman Catholic tradition. They are to some extent paralleled in the present day by the ecstasy and the stigmata of Louise Lateau. And Catholic instinct has discerned that if this modern case be decided to be merely morbid. and in no true sense supernormal, a retrospective discredit will be cast on the earlier legend. The old reluctance of the Catholic Church to submit her phenomena to scientific assessors has therefore to some extent been overcome ; and Catholic physicians, under ecclesiastical authority, have discussed Louise Lateau's case in the form_s of an ordinary medical report. Enough will have been said to indicate the reality of the connection between our inquiries and the preliminary theses of religion. And so far as our positive results go in this direction, they will perhaps carry the more weight in that they are independently obtained, and intended to subserve scientific rather than religious ends ; — coming, indeed, from men who have no developed theory of their own to offer, and are merely following the observed facts wherever they may seem to lead. I see no probability, I may add, that our results can ever supply a convincing proof to any specialised form of religion. The utmost that I anticipate is, that they may afford a solid basis of general evidence to the inde- pendence of man's spiritual nature, and its persistence after death, on which basis, at any rate, religions in their specialised forms may be at one with science, and on which the structure of definite revelation (which must be up-built by historical or moral arguments) may conceivably be planted with a firmness which is at present necessarily lacking. § 12. I have been speaking thus far of religion in its full sense, as a body of doctrine containing some kind of definite assurance as to an unseen world. But the form of religious thought which specially char- acterises our own day is somewhat different from this. We are accustomed rather to varying attempts to retain the spirit, the aroma of religion, even if its solid substratum of facts previously supposed provable should have to be abandoned. The discoursers on things spiritual who have been most listened to in our own day — as Carlyle, Emerson, Mazzini, Renan, Tennyson, Matthew Arnold, Ruskin, etc. — have been to a very small extent dogmatic on the old lines. They have expressed vague, though lofty, beliefs and aspirations, in which the eye of science may perhaps see little substance or validity, but which nevertheless have been in a certain sense more independent, more spontaneous, than of old, since they are less often prompted by any faith instilled from without, and xlviii INTRODUCTION resemble rather the awakening into fuller consciousness of some inherited and instinctive need. And this brings us by an easy transition to the next topic, on which I wish to dwell. For I wish to point out that the emotional creed of edu- cated men is becoming divorced from their scientific creed ; that just as the old orthodoxy of religion was too narrow to contain men's knowledge, so now the new orthodoxy of materialistic science is too narrow to contain their feelings and aspirations ; and consequently that just as the fabric of religious orthodoxy used to be strained in order to admit the discoveries of geology or astronomy, so now also the obvious deductions of material- istic science are strained or overpassed in order to give sanction to feelings and aspirations which it is found impossible to ignore. My inference will, of course, be that in this vaguer realm of thought, as well as in the more distinctly defined branches of knowledge which we have already discussed, the time is ripe for some such extension of scientific knowledge as we claim that we are offering here — an extension which, in my viev/, lifts us above the materialistic standpoint altogether, and which gives at least a possible reality to those subtle intercommunications between spirit and spirit, and even between visible and invisible things, of which Art and Literature are still as full as in any " Age of Faith " which preceded us. I point, then, to the obvious fact that the spread of Materialism has not called into being Materialists only of those simple types which were commonly anticipated a century since as likely to fill a world of complete secularity. Materialists, indeed, of that old unflinching temper do exist, and form a powerful and influential body. It would have been strange, indeed, if recent advances in physiology had not evoked new theories of human life, and a new ideal. For the accepted commonplaces of the old-fashioned moralist are being scattered with a ruthless hand. Our free will, over great portions at least of its once supposed extent, is declared to be an illusion. Our highest and most complex emotions are traced to their rudimentary beginnings in the instincts of self-preservation and reproduction. Our vaunted personality itself is seen to depend on a shifting and unstable synergy of a number of nervous centres, the defect of a portion of which centres may alter our character altogether. And mean- time Death, on the other hand, has lost none of its invincible terrors. The easy way in which our forefathers would speak of " our mortal and im- mortal parts " is hard to imitate in face of the accumulating testimony to the existence of the one element in us, and the evanescence of the other. And since the decay and dissolution of man seem now to many minds to be so much more capable of being truly known than his survival or his further evolution, it is natural that much of the weight which once belonged to the prophets of what man hoped should pass to those who can speak with authority on what man needs must fear. Thus " mad- doctors " tend to supplant theologians, and the lives of lunatics are found to have more lessons for us than the lives of saints. For these thinkers know well that man can fall below himself ; but that he can rise above himself they can believe no more. A corresponding ideal is gradually created ; an id^al of mere sanity and normality, which gets to look op. INTRODUCTION xlix any excessive emotion or fixed idea, any departure from a balanced practicality, with distrust or disfavour, and sometimes rising to a kind of fervour of Philistinism, classes genius itself as a neurosis. The alienists who have taken this extreme view have usually, perhaps, been of opinion that in thus discrediting the higher flights of imagination or sentiment we are not losing much ; that these things are in any case a mere surplusage, and that the ends which life is really capable of attaining can be compassed as well without them. But if the materialistic theory be the true one, these limitations of ideal might well be adopted even by men who would deeply regret what they were thus renouncing. It might well seem that, in abandoning the belief in any spiritual or permanent element in man, it were wise to abandon also that intensity of the affec- tions which is ill adapted to bonds so perishable and insecure, that reach of imagination which befitted only the illusory dignity which was once attached to human fates. But in fact, as I have already implied, the characteristic movement of our own country, at any rate, at the present day, is hardly in this direction. Our prevalent temper is not so much materialistic as agnostic ; and although this renouncement of all knowledge of invisible things does in a sense leave visible things in sole possession of the field, yet the Agnostic is as far as anyone from being " a hog from Epicurus' sty." Rather, instead of sinking into the materialistic ideal of plain sense and physical well-being, the rising schools of thought are transcending that ideal more and more. Altruism in morals, idealism in art, nay, even the sentiment of piety itself, as a decorative grace of life, — all these, it is urged, are consistent with a complete and contented ignorance as to aught beyond the material world. I need not here embark on the controversy as to how far this aspira- tion towards " the things of the spirit " is logically consistent with a creed that stops short with the things of sense. It is quite enough for my present purpose to point out that here also, as in the case of more definite religions, we have a system of beliefs and emotions which may indeed be able to accommodate themselves to modern science, but which are in no sense supported thereby ; rather which science must regard as, at best, a kind of phosphorescence which plays harmlessly about minds that Nature has developed by other processes and for other ends than these. For my argument is that here again, as in the case of religion, tele- pathy, as we affirm it in this book, would be the first indication of a pos- sible scientific basis for much that now lacks not only experimental confirmation, but even plausible analogy. We have seen how much sup- port the preliminary theses of religion may acquire from an assured conviction that the human mind is at least capable of receiving super- normal influences, — is not closed, by its very structure, as the Materialists would tell us, to any " inbreathings of the spirit " which do not appeal to outward eye or ear. And somewhat similar is the added reality which the discovery of telepathy gives to the higher flights, the subtler shades, of mere earthly emotion. " Star to star vibrates light; may soul to soul Strike thro' some finer element of her own ? " 1 INTRODUCTION The lover, the poet, the enthusiast in any generous cause, has in every age unconsciously answered Lord Tennyson's question for himself. To some men, as to Goethe, the assurance of this subtle intercommunica- tion has come with vivid distinctness in some passion -shaken hour. Others, as Bacon, have seemed to gather it from the imperceptible indicia of a lifelong contemplation of man. But the step which actual experimenta- tion, the actual collection and collation of evidence, has now, as we believe, effected, is a greater one than could have been achieved by any individual intuition of bard or sage. For we have for the first time a firm foothold in this impalpable realm ; we know that these unuttered messages do truly travel, that these emotions mix and spread ; and though we refrain as )^et from further dwelling on the corollaries of this far-reaching law, it is not because such speculations need any longer be baseless, but because we desire to set forth the proof of our theorem in full detail before we do more than hint at the new fields which it opens to human thought. § 13. Pausing, therefore, on the threshold of these vaguer promises, I may indicate another direction, in which few will deny that a systematic investigation like ours ought to produce results eminently salutary. It ought to be as much our business to check the growth of error as to pro- mote the discovery of truth. And there is plenty of evidence to show that so long as we omit to subject all alleged supernormal phenomena to a thorough comparative scrutiny, we are not merely postponing a possible gain, but permitting an unquestioned evil. It should surely be needless in the present day to point out that no attempt to discourage inquiry into any given subject which strongly interests mankind, will in reality divert attention from the topic thus tabooed. The savant or the preacher may influence the readers of scientific hand-books, or the members of church congregations, but outside that circle the subject will be pursued with the more excited eagerness because regulating knowledge and experienced guidance are withdrawn. And thus it has been with our supernormal phenomena. The men who claim to have experienced them have not been content to dismiss them as unseasonable or unimportant. They have not relegated them into the background of their lives as readily as the physiologist has rele- gated them into a few paragraphs at the end of a chapter. On the contrary, they have brooded over them, distorted them, misinterpreted them. Where savants have minimised, they have magnified, and the perplexing nodes of marvel which the textbooks ignore, have become, as it were, the ganglia from which all kinds of strange opinions ramify and spread. The number of persons whose minds have been actually upset either by genuine psychical phenomena, or by their fraudulent imitation, is perhaps not large. But the mischief done is by no means confined to these extreme cases. It is mischievous, surely — it clashes roughly with our respect for human reason, and our belief in human progress — that religions should spring up, forms of worship be established, which in effect do but perpetuate a mistake and consecrate a misapprehension, which carry men not forward, but backward in their conception of unseen things. The time has not yet come for an attempt to trace in detail the per- INTRODUCTION li version which each branch of these supernormal phenomena has under- gone in ardent minds ; — the claims to sanctity, revelation, prophecy, which a series of enthusiasts, and of charlatans, have based on each class of marvels in turn. But two forms of creed already mentioned may again be cited as convenient examples — the Irvingite faith of the mis- interpretation of automatism, the Swedenborgian of the misinterpretation of (so-called) clairvoyance. Still more singular have been the resultant beliefs when to the assemblage of purely psychical marvels a physical ingredient has been added, of a more disputable kind. For linked in various ways with records of automatic cerebration, of apparitions, of vision and revelation, come accounts of objective sounds, of measurable movements, which may well seem an unwarrantable intrusion into the steady order of the ponderable world. And in the year 1848 certain events, whose precise nature is still in dispute, occurred in America, in consequence of which many persons were led to believe that under appro- priate circumstances these sounds, these movements, these tangible apparitions, could be evoked or reproduced at will. On this basis the creed of " Modern Spiritualism " has been upbuilt. And here arises the pressing question — notoriously still undecided, difficult and complex beyond any anticipation — as to whether supernormal phenomena of this physical kind do in fact occur at all ; or whether they are in all cases — as they undoubtedly have been in many cases — the product of mere fraud or delusion. This question, as it seems to us, is one to which we are bound to give our most careful attention ; and if we have as yet failed to attain a decisive view, it is not for want of laborious observation, continued by several of us throughout many years. But we are unwilling to pronounce until we have had ample opportunities — opportunities which so far we have for the most part sought in vain — of investigating pheno- mena obtained through private sources, and free, at any rate, from the specific suspicion to which the presence of a " paid medium " inevitably gives rise. I need not add further illustrations of the cautionary, the critical attitude which befits such a Society as ours at the present juncture. This attitude is in one way unavoidably ungracious ; for it has sometimes precluded us from availing ourselves of the labours of predecessors whose zeal and industiy^ we should have been glad to praise. The time, we hope, will come when enough of daylight shall shine upon our path to make possible a discriminating survey of the tracks which scattered seekers have struck out for themselves in the confusion and dimness of dawn. At present we have mainly to take heed that our own groping course shall at least avoid the pitfalls into which others have fallen. Anything like a distribution of awards of merit would be obviously premature on the part of men whose best hope must be that they may conduct the inquiry into a road firm enough to enable others rapidly to outstrip them. II § 14. Enough, however, has now been said to indicate the general tenor of the task which the Society for Psychical Research has under- taken. It remains to indicate the place which the present work occupies Hi INTRODUCTION in the allotted field, and the reasons for offering it to public considera- tion at this early stage of our inquiry. We could not, of course, predict or pre-arrange the order in which opportunities of successful investigation might occur to the searchers in this labyrinth of the imknown. Among the groping experiments which seemed to have only too often led to mere mistake and confusion, — the " thousand pathways " "qua signa sequendi Falleret indeprensus et inremeabilis error," — • it was not easy to choose with confidence our adit of exploration. The approach which proved most quickly productive was one from which it might have seemed that there was little indeed. to hope. A kind of drawing- room game sprang up — it is hard to say whence — a method of directing a subject to perform a desired act by a contact so slight that no conscious impulsion was either received or given. Careful observers soon ranked the " willing-game " as an illustration of involuntary muscular action on the willer's part, affording a guidance to which the subject yielded sometimes without being aware of it. But while the modus operandi of public exhibitions of this misnamed " thought-reading " was not difi&cult to detect, Professor [now Sir William] Barrett was one of the first who — while recognising all these sources of error — urged the duty of persistent watching for any residuum of true thought-transference which might from time to time appear. As will be seen from Chap. II. of this book it was not till after some six years of inquiry and experiment (1876-82) that definite proof of thought-transference in the normal state could be placed before the world. This was done in an article in the Nineteenth Century for June, 1882, signed by Professor Barrett, Mr. Gurney, and my- self. The phenomenon of transmission of thought or sensation without the agency of the recognised organs of sense had been previously recorded in connection with the mesmeric state, but, so far as v>'e know, its occasional occurrence in the normal state was now for the first time m^ntained on the strength of definite experiment. And the four years 1882-1886 have witnessed a great extension of those experiments, which no longer rest on the integrity and capacity of the earliest group of observers alone. § 15. The foundation of the Society for Psychical Research m 1882 gave an opportunity to Mr. Gurne}/ and m3'self, as Hon. Sees, of a Literary Committee, to invite from the general public records of apparitions at or after death, and other abnormal occurrences. On reviewing the evi- dence thus obtained we were struck with the great predominance of alleged apparitions at or near the moment of death. And a new light seemed to be thrown on these phenomena by the unexpected frequency of accounts of apparitions of living persons, coincident with moments of danger or crisis. We were led to infer a strong analogy between our experimental cases of thought-transference and some of these spontaneous cases of what we call telepathy, or transference of a shock or impulse from one Uving person to another person at such a distance or under such conditions as to negative the possibility of any ordinary mode of transmission. An article, signed by Mr. Gurney and myself, in the Fortnightly Review for March, 1883, gave a first expression to the analogy thus suggested. The INTRODUCTION liii task of collection and scrutiny grew on our hands ; Mr. Podmore undertook to share our labours ; and the Council of the Society for Psychical Research requested us to embody the evidence received in a substantive work. It will be seen, then, that the theory of Telepathy, experimental and spontaneous, which forms the main topic of this book, was not chosen as our theme by any arbitrary process of selection, but was irresistibly suggested by the abundance and the convergence of evidence tending to prove that special thesis. We were, and are, equally g-nxions to inquire into many other alleged marvels — clairvoyance, haunted houses. Spiritual- istic phenomena, etc. — but telepathy is the subject which has first shown itself capable of investigation appearing to lead to a- positive result ; and it seemed well to arrange its evidence with sufficient fulness to afford at least a solid groundwork for further inquiry. And having been led to this choice by the nature of the actual evi- dence before us, we may recognise that there is some propriety in dealing first with an issue which, complex though it is, is yet simple as compared to other articles of our programme. For the fact, if it be one, of the direct action of mind upon mind has at least a generality which makes it possible that, like the law of atomic combination in chemistry, it may be a generalisation which, though grasped at first in a very simplified and imperfect fashion, may prove to have been the essential pre-requisite of future progress. § 1 6. In a certain sense it may be said that this hidden action of one mind on another comes next in order of psychical discovery to the hidden action of the mind within itself. It will be remembered that the earliest scientific attempts to explain the phenomena of so-called Spiritual- ism referred them mainly to " unconscious cerebration " (Carpenter), or to what was virtually the same thing, " unconscious muscular action " (Faraday). Now these theories, in my view, were, so far as they went, not only legitimate, but the most logical which could have been suggested to explain the scanty evidence with which alone Faraday and Carpenter attempted to deal. This unconscious action of the mind was in reality the first thing which it was needful to take into account in approaching supernormal phenomena. I believe, indeed, that our knowledge of those hidden processes of mentation is still in its infancy, and I have elsewhere endeavoured to assign a wider range than orthodox science has yet ad- mitted to the mind's unconscious operation. ^ But the result of this further analysis has been (as I hold) not to show that ordinary physiological considerations will suffice (as Dr. Carpenter seems to suppose) to explain all the psychical problems involved, but rather to reveal the fact that these unconscious operations of the mind do not follow the familiar channels alone, but are themselves the facilitation or the starting-point of operations which to science are wholly new. To state the matter broadly, so as to include in a common formula the unremembered utterances of the hypnotic subject, and the involuntary writings of the waking automatist, I would maintain that when the horizon of consciousness is altered, the opening field of view is not always or wholly ^ See Proceedings of the S.P.R., Vols. ii. and iii. * liv] INTRODUCTION filled by a mere mirage or refraction of objects already familiar, but does, on rare occasions, include new objects, as real as the old. And amongst the novel energies thus liberated, the power of entering into direct communication with other intelligences seems to stand plainly forth. Among the objects in the new prospect are fragments of the thoughts and feelings of distant minds. It seems, at any rate, that some element of telepathy is perpetually meeting us throughout the whole range of these inquiries. In the first place, thought-transference is the only super- normal phenomenon which we have as yet acquired the power of inducing, even occasionally, in the normal state. It meets us also in the hypnotic trance, under the various forms of " community of sensation," " silent willing," and the like. Among the alleged cases of " mesmeric clair- voyance " the communication of pictures of places from operator to subject seems the least uncertain ground. And again, among phenomena commonly attributed to " spirits " (but many of which may perhaps be more safely ascribed to the automatic agency of the sensitive himself), communication of thought still furnishes our best clue to " trance- speaking," " clairvoyant vision," answers to mental questions and the like. It need not, therefore, surprise us if, even in a field so apparently remote from all ordinary analogies as that of apparitions and death- wraiths, we still find that telepathy affords our most satisfactory clue. § 17. And here would seem to be the fitting place to explain why we have given the title of " Phantasms of the Living " to a group of records most of which will present themselves to the ordinary reader as narra- tives of apparitions of the dead. When we began, in a manner to be presently described, to collect accounts of experiences which our informants regarded as inexplicable by ordinary laws, we were of course ignorant as to what forms these experiences would mainly take. But after printing and considering over two thousand depositions which seemed primd facie to deserve attention, we find that more than half of them are narratives of appear- ances or other impressions coincident either with the death of the person seen or with some critical moment in his life-history. The value of the accounts of apparitions after death is lessened, more- over, by a consideration which is obvious enough as soon as these narra- tives come to be critically considered. The difficulty in dealing with all these hallucinations — with all appearances to which no persistent three-dimensional reality corresponds — is to determine whether they are veridical, or truth-telling — whether, that is, they do in fact correspond to some action which is going on in some other place or on some other plane of being ; — or whether, on the other hand, they are merely morbid or casual — the random and meaningless fictions of an over-stimulated eye or brain. Now, in the case of apparitions at the moment of death or crisis, we have at any rate an objective fact to look to. If we can prove that a great number of apparitions coincide with the death of the person seen, we may fairly say, as we do say, that chance alone cannot explain this coincidence, and that there is a causal connection between the two events. But if I have a vision of a friend recently dead, and on whom my thoughts have been dwelling, we cannot be sure that this may not INTRODUCTION Iv be a merely delusive hallucination — the mere offspring of my own brooding sorrow. In order to get at all nearly the same degree of evidence for a dead person's appearance that we can get for a dying person's appearance, it seems necessary that the apparition should either communicate some fact known only to the deceased, or should be noted independently by more than one person at once or successively. And our evidence of this kind is at present scarcely sufficient to support any assured conclusion. ^ When, therefore, we are considering whether the phantasms of dying persons may most fitly be considered as phantasms of the dead or of the living, we find little support from analogy on the side of posthumous apparitions. And on the other hand, as already hinted, we have many cases where the apparition has coincided with violent shocks, — carriage accidents, fainting fits, epileptic fits, etc., which nevertheless left the agent — as we call the person whose semblance is seen, — as much alive as before. In some cases the accident is almost a fatal one ; as when a man's phantom is seen at the moment when he is half-drowned and in- sensible. In such a case it would seem illogical to allow the mere fact of his restoration or non-restoration to life to rank his phantom as that of a living person in the one case, of a dead person in the other. It seems simpler to suppose that if two men fall overboard to-day and their respec- tive phantoms are seen by their friends at the moment, — then, though one man should be restored to life and the other not, — yet if the first phantom was that of a living man, so also was the second. Nay more, even if the apparition be seen some hours later than the moment of apparent death, there are still reasons which prevent us from decisively classing it as the apparition of a dead man. In the first place, the moment of actual death is a very uncertain thing. When the heart's action stops the organism continues for some time in a state very different from that of ordinary inanimate matter. In such an inquiry as ours it is safer to speak, not of death, but of " the process of dissolution," and to allow for the possible prolongation of some form of psychical energy even when, for instance, the attempt to restore respiration to a drowned man has definitely failed. And in the second place, we find in the case of phantasms corresponding to some accident or crisis which befalls a living friend, that there seems often to be a latent period before the phantasm becomes definite or externalised to the percipient's eye or ear. Sometimes a vague malaise seems first to be generated, and then when other stimuli are deadened, — as at night or in some period of repose, — the indefinite grief or uneasiness takes shape in the voice or figure of the friend who in fact passed through his moment of peril some hours before. It is quite possible that a deferment of this kind may sometimes intervene between the moment of death and the phantasmal announce- ment thereof to a distant friend. These, then, are reasons, suggested by actual experience, for ascribing our phantasms at death to living rather than to dead men. And there is another consideration, of a more general order, which points in the sfime direction. We must not rashly multiply the problems involved in this difficult inquiry. Now Science, it is needless to say, offers no assur- ^ See Mrs. Sidgwick's paper on " The Evidence, collected by the Society, for Phantasms of the Dead," in Proceedings of the S.P.R., vol. iii. Ivi INTRODUCTION ance that man survives the tomb ; and although in Christian countries our survival is an established doctrine, this does not carry with it any dogma as to the possibility that communications should reach us from departed spirits. The hypothesis, then, that apparitions are ever directly caused by dead persons is one which ordinary scientific caution bids us to be very slow in introducing. Should it afterwards be established that departed spirits can communicate with us, the interpretation placed upon various cases contained in this volume may need revision. But for the present it is certainly safer to inquire how far they can be explained by the influences or impressions which, as we know by actual experiment, living persons can under certain circumstances exert or effect on one another, in those obscure supersensory modes which we have provision- ally massed together under the title of Telepathy. § 1 8. The main theses of this book, then, are now capable of being stated in a very simple form. I. Experiment proves that telepathy — the supersensory^ transference of thoughts and feelings from one mind to another — is a fact in Nature. II. Testimony proves that phantasms (impressions, voices, or figures) of persons undergoing some crisis, — especially death, — are perceived by their friends and relatives with a frequency which mere chance cannot explain. III. These phantasms then, whatever else they may be, are instances of the supersensory action of one mind on another. The second thesis therefore confirms, and is confirmed by, the first. For if telepathy exists, we should anticipate that it would exhibit some spontaneous manifestations, on a scale more striking than our experimental ones. And, on the other hand, apparitions are rendered more credible and comprehensible by an analogy whch for the first time links them with the results of actual experiment. Such are the central theses of this work, — theses on which its authors, and the friends whom the}^ have mainly consulted, are in entire agree- ment. The first thesis may, of course, be impugned by urging that our experiments are fallacious. The second thesis may be impugned by urging that our testimony is insufficient. The third thesis, as I have here worded it, is hardly open to separate attack ; being a corollary which readily follows if the first two theses are taken as proved. This, however, is only the case so long as the third thesis, which asserts the analogy between thought-transference and apparitions — between experimental and spontaneous telepathy — is stated in a vague and general form. So soon as we attempt to give more precision to this analogy — to discuss how far the unknown agency at work can be supposed to be the same in both cases — or how far the apparitions may be referable to quite other, though cognate, laws, — we enter on a field where even those who have accepted the analogy in general terms are likely to find the evidence leading them to somewhat divergent conclusions. Of two men independently studying our records of apparitions, the one will almost inevitably press their analogy to simple telepathy further than the other. And each will be able to plead that he has been guided as far ^ By " supersensory " I mean " independent of the recognised channels of sense" I do not mean to assert that telepathic perception either is or is not analogous to sensory perception of the recognised kinds. INTRODUCTION Irii as possible by an instinct of scientific caution in thus judging of matters strange and new. The first will say that " causes are not to be multiplied without necessity," and that we have now in telepathy a vera causa whose furthest possibilities we ought to exhaust before invoking still stranger, still remoter agencies, whose very existence we are not in a position to prove. He will feel bound therefore to dwell on the points on which our knowledge either of telepathy, or of the mechanism of hallucinations in general, throw some light ; and he will set aside as at present inexplicable such peculiarities of our evidence as cannot well be brought within this scheme. The second inquirer, on the other hand, will perhaps feel strongly that telepathy, as we now know it, is probably little more than a mere pre- liminary conception, a simplified mode of representing to ourselves a group of phenomena which, as involving relations between minds, may probably be more complex than those which involve even the highest known forms of matter. He will feel that, while we hold one clue alone, we must be careful not to overrate its efficacy ; we must be on the watch for other approaches, for hints of inter-relation between disparate and scattered phenomena. It is to the first of these two attitudes of mind, — the attitude which deprecates extraneous theorising, — that Mr. Gurney and Mr. Podmore have inclined ; and the committal of the bulk of this work to Mr. Gurney's execution indicates not only that he has been able to devote the greatest amount of time and energy to the task, but also that his view is on the whole the most nearly central among the opinions which we have felt it incumbent on us to consult. We have no wish, however, to affect a closer agreement than actually exists ; and in a " Note on a Suggested Mode of Psychical Interaction " [omitted in the present edition. — Ed.], I shall submit a view which differs from Mr. Gurney's on some theoretical points. § ig. The theories contained in this book, however, bear a small proportion to the mass of collected facts. A few words as to our method of collection may here precede Mr. Gurney's full discussion (Chapter IV) of the peculiar difficulties to which our evidence is exposed. It soon became evident that if our collection was to be satisfactory it must consist mainly of cases collected by ourselves, and of a great number of such cases. ^ The apparitions at death, etc., recorded by previous writers, are enough, indeed, to show that scattered incidents of the kind have obtained credence in many ages and conntries. But they have never been collected and sifted with any systematic care ; and few of them reach an evidential standard which could justify us in laying them before our readers. And even had the existing stock of testimony been large and well-assured, it would still have been needful for us to collect our own specimens in situ, — to see, talk with, and correspond with the persons to whose strange experiences so much weight was to be given. This task of personal inquiry, — whose traces will, we hope, be sufficiently apparent throughout the present work, — has stretched itself out beyond expectation, but has also enabled us to speak with a con- ^ [The presenfcatioQ of tMs "great number " of cases has been impossible in this abridged edition, and those retained must be regarded ae typical rather than as impressive by their number. — Ed.] Iviii INTRODUCTION fidence which could not have been otherwise acquired. One of its ad- vantages is the security thus gained as to the bona fides of the witnesses concerned. They have practically placed themselves upon their honour ; nor need we doubt that the experiences have been, as a rule, recounted in all sincerity. As to unintentional errors of observation and memory, Mr. Gurney's discussion will at least show that we have had abundant opportunities of learning how wide a margin must be left for human carelessness, forgetfulness, credulity. " God forbid," said the flute- player to Philip of Macedon, " that your Majesty should know these things as well as 1 1 " It must not, however, be inferred from what has been said that our informants as a body have shown themselves less shrewd or less accurate than the generality of mankind. On the contrary, we have observed with pleasure that our somewhat persistent and probing method of inquiry has usually repelled the sentimental or crazy wonder-mongers who hang about the outskirts of such a subject as this ; while it has met with cordial response from an unexpected number of persons who feel with reason that the very mystery which surrounds these incidents makes it additionally important that they should be recounted with sobriety and care. The straightforward style in which most of our informants have couched their narratives, as well as the honoured names which some of them bear, may enable the reader to share something of the confidence which a closer contact with the facts has inspired in our own minds. Again, it seemed necessary that the collection offered to the public should be a very large one, even at the cost of including in a Supplement [omitted in the present edition. — Ed.] some remote or second-hand cases besides the first-hand cases which alone are admitted into the chapters of this book. If, indeed, our object had been simply to make out a case for the connection of deaths with apparitions, we might have offered a less assailable front, and should certainly have spared ourselves much trouble, had we confined ourselves to giving in detail a few of the best-attested instances. But what we desired was not precisely this. We hope, no doubt, that most of our readers may ultimately be led to conclusions resembling our own. But before our conclusions can expect to gain general acceptance, many other hypotheses will doubtless be advanced, and coincidence, superstition, fraud, hysteria, will be invoked in various combinations to explain the evidence given here. We think, therefore, that it is our duty in so new a subject to afford full material for hj^potheses discordant with our own ; to set forth cases drawn from so wide a range of society, and embracing such a variety of circumstances, as to afford scope for every mode of origination or development of these narratives which the critic may suggest. Furthermore, the whole subject of hallucinations of the sane — which hitherto has received very scanty treatment — seems fairly to belong to our subject, and has been treated by Mr. Gumey in Chapter XI. We have throughout contended that a knowledge of abnormal or merely morbid phenomena is an indispensable pre-requisite for the treating of any supernormal operations which may be found to exist under somewhat similar forms of manifestation. INTRODUCTION lix Once more, it was plainly desirable to inquire whether hypotheses, now admitted to be erroneous, had ever been based in past times on evidence in any way comparable to that which we have adduced. The belief in witchcraft, from its wide extent and its nearness to our own times, is the most plausible instance of such a parallelism. And Mr. Gurney, in his Note on Chapter IV [omitted in the present edition. — Ed.], has given the results of an analysis of witch-literature more laborious than previous authors had thought it worth while to undertake. The result is remarkable ; for it appears that the only marvels for which respectable testimony was adduced consist obviously of ignorant descriptions of hypnotic and epileptiform phenomena now becoming familiar to science ; while as to the monstrous stories — copied from one uncritical writer into another — which have given to this confused record of hypnotic and hysterical illusions the special aromas (so to say) of witchcraft or lycan- thropy, — these prodigies have scarcely ever the slightest claim to be founded on any first-hand evidence at all. § 20. But while the material here offered for forming an opinion on all these points is, no doubt, much larger than previous writers have been at the pains to amass, we are anxious, nevertheless, to state explicitly that we regard this present collection of facts as merely preliminary ; this present work as merely opening out a novel subject ; these researches of a few persons during a few years as the mere first instalment of inquiries which will need repetition and reinforcement to an extent which none of us can as yet foresee. A change in the scientific outlook so considerable as that to which this volume points must needs take time to accomplish. Time is needed not only to spread the knowledge of new facts, but also to acclimatise new conceptions in the individual mind. Such, at least, has been our own experience ; and since the evidence which has come to us slowly and piecemeal is here presented to other minds suddenly and in a mass, we must needs expect that its acceptance by them will be a partial and gradual thing. What we hope for first is an increase in the number of those who are willing to aid us in our labours ; we trust that the fellow- workers in many lands to whom we already owe so much may be en- couraged to further collection of testimony, renewed experiment, when they see these experiments confirming one another in London, Paris, Berlin, — this testimony vouching for cognate incidents from New York to New Zealand, and from Manchester to Calcutta. With each year of experiment and registration we may hope that our results will assume a more definite shape — that there will be less of the vagueness and confusion inevitable at the beginning of a novel line of research, but naturally distasteful to the savant accustomed to proceed by measurable increments of knowledge from experimental bases already assured. Such an one, if he reads this book, may feel as though he had been called away from an ordnance survey, conducted with a competent staff and familiar instruments, to plough slowly with inexperienced mariners through some strange ocean where beds of en- tangling seaweed cumber the trackless way. We accept the analogy ; but we would remind him that even floating weeds of novel genera may Ix INTRODUCTION foreshow a land unknown ; and that it was not without ultimate gain to men that the straining keels of Columbus first pressed through the Sargasso Sea. § 21. Yet one word more. This book is not addressed to savants alone, and it may repel many readers on quite other than scientific grounds. Attempting as we do to carry the reign of Law into a sanctuary of belief and emotion which has never thus been invaded in detail, — lying in wait, as it w^ere, to catch the last impulse of the dying, and to question the serenity of the dead, — we may seem to be incurring the poet's curse on the man " who would peep and botanize upon his mother's grave," — to be touching the Ark of sacred mysteries with hands stained with labour in the profane and common field. How often have men thus feared that Nature's wonders would be degraded by being closelier looked into ! How often, again, have they learnt that the truth was higher than their imagination ; and that it is man's work, but never Nature's, which to be magnificent must remain unknown ! How would a disciple of Aristotle, — fresh from his master's conception of the fixed stars as types of godhead, — of an inhabitance by pure exist- ences of a supernal v/orld of their own, — how would he have scorned the proposal to learn more of those stars by dint of the generation of fetid gases and the sedulous minuteness of spectroscopic analysis ! Yet how poor, how fragmentary were Aristotle's fancies compared with our con- ception, thus gained, of cosmic unity ! our vibrant message from Sirius and Orion by the heraldry of the kindred flame ! Those imagined gods are gone ; but the spectacle of the starry heavens has become for us so moving in its immensity that philosophers, at a loss for terms of wonder, have ranked it with the Moral Law. If man, then, shall attempt to sound and fathom the depths that lie not without him, but within, analogy may surely warn him that the first attempts of his rude psychoscopes to give precision and actuality to thought will grope among " beggarly elements," — will be concerned with things grotesque, or trivial, or obscure. Yet here also one hand's-breadth of reality gives better footing than all the castles of our dream ; here also by beginning with the least things we shall best learn how great things may remain to do. The insentient has awoke, we know not how, into sentiency ; the sentient into the fuller consciousness of hum.an minds. Yet even human self-consciousness remains a recent, a perfunctory, a superficial thing ; and we must first reconstitute our conception of the microcosm, as of the macrocosm, before we can enter on those " high capacious powers " which, I believe, " lie folded up in man." F. W. H. M. CHAPTER I PRELIMINARY REMARKS: GROUNDS OF CAUTION § I. Whatever the advances of science may do for the universe, there is one thing that they have never yet done and show no prospect of doing — namely, to make it less marvellous. Face to face with the facts of Nature, the wonderment of the modern chemist, physicist, zoologist, is far wider and deeper than that of the savage or the child ; far wider and deeper even than that of the early workers in the scientific field. True it is that science explains ; if it did not it would be worthless. But scientific explanation means only the reference of more and more facts to immutable laws ; and, as discovery advances in every department, the orderly marvel of the comprehensive laws merely takes the place of the disorderly marvel of arbitrary occurrences. The mystery is pushpd back, so to speak, from facts in isolation to facts in the aggregate ; but at every stage of the process the mystery itself gathers new force and impress! veness. What, then, is the specific relation of the man of science to the pheno- mena which he observes ? His explanation of them does not lead him to marvel at them less than the uneducated person : what does it lead him to do for them that the uneducated person cannot do ? "To predict them with certainty," it will no doubt be replied ; " which further implies, in cases where the conditions are within his control, to produce them at will." But it is important to observe that this power of prediction, though constantly proclaimed as the authoritative test of scientific achievement, is very far indeed from being an accurate one. For it is a test which is only fulfilled with anything like completeness by a small group of sciences — those which deal with inorganic nature. The physicist can proclaim with confidence that gravitation, and heat, and electricity (as long as they act at all) will continue to act as they do now ; every discovery that the chemist makes about a substance is a prophecy as to the behaviour of that class of substance for ever. But as soon as vital organisms appear on the scene, there is a change. Not only do the com- plexities of structure and process, and the mutual reactions of the parts and the whole, exclude all exact quantitative formulae ; not only is there an irreducible element of uncertainty in the behaviour from moment to moment of the simplest living unit; but there appear also developments, and varieties and " sports," which present themselves to us as arbitrary — which have just to be registered, and cannot be explained. Not, of course, that they are really arbitrary ; no scientifically trained mind B 2 PRELIMINARY REMARKS : [Chap. I entertains the least doubt that they are in every case the inevitable results of prior conditions. But the knowledge of the expert has not approximately penetrated to the secret of those conditions ; here, there- fore, his power of prediction largely fails him. This applies to a great extent even to events of a uniform and familiar order. Biological science may predict that an animal will be of the same species as its parents ; but cannot predict its sex. It may predict the general characteristics of the next generation of men ; but not the special attributes of a single individual. But its power of forecast is limited in a far more striking wajj- — by the perpetual modification of the very material with which it has to deal. It is able to predict that, given such and such variations, natural selection will foster and increase them ; that given such and such organic taints, heredity will transmit them : but it is powerless to say what the next spontaneous variation, or the next development of heredity will be. It is at work, not on steadfast substances with immutable qualities, like those of the inorganic world ; but on substances whose, very nature is to change. The evolution of animal existence, from protoplasm upwards, involves ever fresh elabora- tions in the composition of the vital tissues. Science traces the issue of these changes, and learns even to some extent to foresee and so to guide their course ; it can thus lay down laws of scientific breeding, laws of medicine and hygiene. But the unconquerable spontaneity of the organic world is for ever setting previous generalisations at defiance ; in great things and small, from the production of a new type of national physique to the production of a new variety of tulip, it is ever presenting fresh developments, whose necessity no one could divine, and of which no one could say aught until they were actually there. And so, though science follows closely after, and keeps up the game with spirit, its position in its Wonderland is always rather like that of Alice in hers, when the croquet-hoops consisted of soldiers who moved as often as they chose. The game is one on which it will never be safe to bet for very far ahead ; and it is one which will certainly never end. And if this is true of life in its physical manifestations, it is certainly not less true of its mental manifestations. It is to the latter, indeed, that we naturally turn for the highest examples of mobility, and the most marked exhibitions of the unaxpected. An Athenian of Solon's time, speculating on " the coming race," might well have predicted for his countrymen the physical prowess that won Marathon, but not the peculiar intellectual vitality that culminated in the theatre of Dionj'sus. At the present moment, it is safer to prophesy that the next generation in Ger- many will include a good many hundreds of thousands of short-sighted persons than that it will include a Beethoven. Nor will it surprise us to find the " sports " and uncertainties of vital development most conspicuous on the psychical side, if we remember the nature of their physical basis. For mental facts are indissolubly linked vv^ith the very class of material facts that science can least penetrate — with the most complex sort of changes occurring in the most subtly woven sort of matter—the molecular activities of brain-tissue. § 2. There exists, then, a large department of natural events where Chap. I] GROUNDS OF CAUTION 3 the test of prediction can be applied only in a restricted way. Whether the events be near or distant — whether the question be of intellectual developments a thousand years hence, or of the movements of an amceba or the success of a " thought-transference " experiment in the next five m.inutes — there is here no voice that can speak with absolute authority. The expert gets his cosmic prophecies accepted by pointing to the per- petual fulfilment of his minor predictions in the laboratory ; or he refutes adverse theories by showing that they conflict with facts that he can at any moment render patent. But as to the implications and possibilities of life — the constitution and faculties of man — he will do well to predict and refute with caution ; for here he may fail even to guess the relation of what will be to what is. If his function as a prophet is not wholly abrogated, he is a prophet ever liable to correction. He is obliged to deal largely in likelihoods and tendencies ; and (if I may venture on a prophecy which is perhaps as fallible as the rest) the interest in the laws that he is able to lay down will never supersede the interest in the exceptions to those laws. Indeed it is in emphasising exceptions that his own role will largely consist. And above all must he beware of setting up any arbitrary " scientific frontier " between the part of Nature that he knows and the part that he does not know. He can trace the great flood of evolution to the point at which he stands ; but a little beyond him it loses itself in the darkness ; and though he may realise its general force and direction, and roughly surmise the mode in which its bed will be shaped, he can but dimly picture the scenes through which it v/ill flow. But if the science of life cannot be final, there is no reason why it should not be accurate and coherent. And if the scope of definite scientific comprehension is here specially restricted, and the unexpected is specially certain to occur, that is no reason for abating one jot of care in the actual work that it remains possible to do — the work of sifting and marshalling evidence, of estimating sources of error, and of strictly adjusting theories to facts. On the contrary, the necessity for such care is only increased. If incaution may be sometimes shown in too peremptorily shutting the door on alleged phenomena which are not in clear continuity with established knowledge, it is far more often and flagrantly shown in the claim for their admission. And it is undeniable that the conditions which have been briefly described expose speculation on the possible developments of vital phenomena to peculiar dangers and difficulties. In proportion as the expert moderates his tone, and makes his forecasts in a tentative and hypothetical manner, it is certain that those who are not experts will wax bold in assertion and theory. The part of the map that science leaves blank, as terra incognita, is the very one which amateur geographers will fill in according to their fancy, or on the reports of uncritical and untrustworthy explorers. The confidence of ignorance is always pretty accurately adjusted to the confidence of knowledge. Wherever the expert can put his foot down, and assert or deny with assurance, the uninstructed instinctively bow to him. He fearlessly asserts, for instance, that the law of the conservation of energy cannot be broken ; the world believes him, and the inventors of perpetual-motion machines graduallj'^ die off. But suppose the question is of possible relations of human beings to in- animate things or to one another, new modes of influence, new forms of 4 PRELIMINARY REMARKS : [Chap. I sensitiveness. Here responsible science can give no confident denial ; here, therefore, irresponsible speculation finds its chance. It has, no doubt, modified its language under the influence of half a century of brilliant physical discovery. It takes care to shelter its hj'-potheses under the name of law : the loosest of philosophers nowadays would hesitate to appeal, as the elder Humboldt appealed sixty years ago, to a " sense of yearning in the human soul," as a proof that the course of nature may suSer exceptions.^ But the change is often rather in name than in fact ; the " natural " lends itself to free guessing quite as easily as the " super- natural " ; and nowhere in Nature is this freedom so unchartered as in the domain of psychic life. Speculation here is not only easy ; it is, un- fortunately, also attractive. The more obscure phenomena and the more doubtful assumptions are just those on which the popular mind most readily fastens ; and the popular tongue rejoices in terms of the biggest and vaguest connotation. Something also must be set down to a natural reaction. Even persons whose interest has been earnest and intelligent have found scientific moral hard to preserve, in departments surrendered by a long-standing convention of unscientific treatment. Thus, in their practice, they have come to acquiesce in that surrender, and have dis- pensed with habits of caution for which no one was likely to give them credit ; while in their polemic they have as much resented the stringent demands for evidence, in which their opponents have been right, as the refusal to look at it when it is there, in which their opponents have been wrong. § 3. The above facts, and the peculiar obligations which they involve, should never be lost sight of by the serious student of " psychical "* phenomena. His path is one that eminently craves wary walking. On the one hand, he finds new dim vistas of study opening out, in an age whose ideal of scientific studies is formed from the most highly developed specimens of them ; and the twilight which has in every class of know- ledge preceded the illuminating dawn of law is made doubly dark and dubious for him by the advanced daylight of scientific conceptions from which he peers into it. He finds, moreover, that the marvellous recent extension of the area of the known through additions to its recognised departments and multiplication of their connections, has inevitably and reasonably produced a certain rigidity of scientific attitude — an increased difficulty in breaking loose from association, and admitting a new depart- ment on its own independent evidence. And on the other hand, he finds himself more or less in contact v;ith advocates of new departments who ignore the weight of the presumption against them — who fail to see that it is from the recognised departments that the standard of evidence ^ Briefe an eine Freiindin, p. 61. ^ The specific sense which we have given to this word needs apology. But we could find no other convenient term, under which to embrace a group of subjects that lie on or outside the boundaries of recognised science, while seeming to present certain points of connection among themselves. For instance, this book will contain evidences of the relation of telepathy — its main theme — both to mesmerism and to certain phenomena which are often, without adequate evidence, attributed to mind.s apart from material organisms. Chap. I] GROUNDS OF CAUTION 5 must be drawn, and that if speculation is to make good its right to outrun science, it will certainly not be by impatience of scientific canons. On this side the position of the psychical student is one in which the student of the recognised sciences is never placed. The physicist never finds his observa- tions confronted or confounded with those of persons who claim familiarity with his subject while ignoring his methods : he never sees his statements and his theories classed or compared with theirs. He is marked out from his neighbours by the very fact of dealing with subject-matter which they do not know how even to begin to talk about. The " psychicist" is not so marked out. His subject matter is in large measure common property, of which the whole world can talk as glibly as he ; and the ground which must be broken for science, if at all, by the application of precise treatment, has already been made trite in connection with quite other treatment. § 4. The moral is one which the authors of the present undertaking have every reason to lay to heart. For the endeavour of this book, almost throughout, is to deal with themes that are in a sense familiar, by the aid, partly, of improved evidential methods, but partly also of concep- tions which have as yet no place in the recognised psychology. Not, indeed, that the reader is about to be treated to any large amount of speculation ; facts will be A-ery much more prominent than theories. Still, the facts to be adduced carry us at least one step beyond the accepted boundaries. What they prove (if we interpret them rightly) is the ability of one mind to impress or to be impressed by another mind otherwise than through the recognised channels of sense. We call the owner of the im- pressing mind the agent, and the owner of the impressed mind the percipient ; and we describe the fact of impression shortly by the term telepathy. We began by restricting that term to cases where the distance through which the transference of impressions took place far exceeded the scope of the recognised senses ; but it may be fairly extended to all cases of impressions convej'ed without an}' affection of the percipient's recognised senses, whatever may be his actual distance from the agent. I of course do not mean by this merely that the channel of communication is unrecognised by the person impressed — as in the drawing-room pastime where hidden pins are found through in- dications which the finder receives and acts on without any consciousness of guidance. By the words " otherwise than through the recognised channels of sense," I mean that the cause or condition of the transferred impression is specifically unknown. It may sometimes be necessary or convenient to conceive it as some special supernormal or supersensuous^ faculty ; and in that case we are undoubtedly assuming a faculty which is new — or at any rate is new to science. But we can at least claim that we take this step under compulsion ; not in the light-hearted fashion which formerly improvised occult forces and fluids to account for the 1 It seems impossible to avoid these terms ; yet each needs to be guarded from a probable misunderstanding. Svpernormal is very liable to be confounded with super- natural ; while supersens^wu■s suggests a dogmatic denial of a physical side to the effect. 6 PRELIMINARY REMARKS : [Chap. I vagaries of hysteria ; or which in our own day has discovered the dawn of a new sense, or the reUc of some primeval instinct, in the ordinary exhibitions of the " willing-game." Our inference of an unrecognised mode of affection has nothing in common with such inferences as these ; for it has been made only after recognised modes have been carefully excluded. § 5. It is not, however, with the ultimate conditions of the phenomena that the study of them can begin : our first business is with the reality, rather than with the rationale, of their occurrence. Telepathy as a system of facts is what we have to examine. Discussion of the nature of the novel faculty in itself, and apart from particular results, will be as far as possible avoided. That, if it exists, it has important relations to various very fundamental problems — meta.physical, psychological, possibly even physical — can scarcely be doubted. So far from the scientific study of man being a region whose boundaries are pretty well mapped out, and which only requires to be filled in with further detail by physiologists and psycho- logists, we may come to perceive that we are standing only on the thresh- old of a vast terra incognita, which must be humbly explored before we can even guess at its true extent, or appreciate its relation to the more familiar realms of knowledge. But such distant visions had better not be lingered over. Before the philosophical aspects of the subject can be profitably discussed, its position as a real department of knowledge must be amply vindicated. This can only be done by a wide survey of evidence ; the character of the present treatise will therefore be mainly evidential. In demonstrating the reality of impressions communicated otherwise than through the known sensory channels, Vv^e rely on two distinct branches of evidence, each of which demands a special sort of caution. The larger portion of this work will deal with cases of spontaneous occurrence. Here the evidence will consist of records of experiences which we have received from a variety of sources — for the most part from living persons more or less known to us. Narratives of the same kind have from time to time appeared in other collections. These, however, have not been treated with any reference to a theory of telepathy such as is here set forth ; nor have their editors fulfilled conditions which, for reasons to be subsequently explained (Chapter IV) , we have felt bound to observe ; and we have found them of almost no assistance. In scarcely a single instance has a case been brought up to the standard which really commands attention. ^ The prime essentials of testimony in such matters — authorities, names, dates, corroboration, the ipsissima verba of the witnesses — have one or all been lacking ; and there seems to have been no appreciation of the strength of the d. priori objections which the evidence has to overmaster, nor of the possible sources of error in the evidence itself. It is in analysing and estimating these sources of error, and in fixing the evidential standard ' An exceplion sboulrl peiliaps be made in favour of a few of the late Mr. E. Dale Owen'.s narratives. The Rev. B. 'Wrcy-Savile's book on Apparitions contains some careful work, but it deals chiefly with remote cases. Dr. Mayo, in his Truths contmned in Popular Supcrslitions, adduces very inadequate evidence : but he has given (p.67) what is perhaps the first suggestion of a p.sychical explanation. Chap. I] GROUNDS OF CAUTION 7 which may fairly be applied, that the most difficult part of the present task will be seen to consist. But though the records here presented will be more numerous, and on the whole better attested, than those of previous collections, the majority of them will be of a tolerably v/ell-known type. The peculiarity of the present treatment will come out rather in the connection of this branch of our evidence with the other branch. For our conviction that the supposed faculty of supersensuous impression is a genuine one is greatly fortified by a body of evidence of an experimental kind — where the conditions could be arranged in such a way as to exclude the chances of error that beset the spontaneous cases. In considering this experi- mental branch of our subject, I shall of course, after what has been said, be specially bound to make clear the distinction between what we hold to be genuine cases and the spurious " thought-reading " exhibitions which are so much better known. This will be easy enough, and will be done in the next chapter. CHAPTER II THE EXPERIMENTAL BASIS: THOUGHT-TRANSFERENCE § I. It IS difficult to get a quite satisfactory name for the experimental branch of our subject. " Thought-reading " was the name that we first adopted ; but this had several inconveniences. Oddly enough, the term has got identified with what is not thought-Teading at all, but muscle-residmg — of which more anon. But a more serious objection to it is that it suggests a power to read anything that may be going on in the mind of another person — to probe characters and discover secrets — which raises a needless prejudice against the whole subject. The idea of such a power has, in fact, been converted into an ad absurdum argument against the existence of the faculty for which we contend. To suppose that people's minds can be thus open to one another, it was justly enough said, would be to contradict the assumption on which all human inter- course has been carried on. Our answer, of course, is that we have never supposed pcOjple's minds to be thus open to one another ; that such a supposition would be as remote as possible from the facts on which we rely ; and that the most accomplished " thought-reader's " power is never likely to be a matter of social inconvenience. The mode of experi- mentation may reassure those who look on the genuine faculty as dangerous or uncanny ; for the results, as a rule, have to be tried for by a distinct, and often a very irksome, process of concentration on the part of the person whose " thought " is to be " read." And this being so, it is clearly important to avoid such an expression as " thought-reading," which conveys no hint that his thought is anything else than an open page, or that his mental attitude has anything to do with the phenomenon. The experiments involve, in fact, the will of two persons ; and of the two minds, it is rather the one which reads that is passive and the one M^hicli is read that is active. It is for the sake of recognising this that we distinguish the two parties as " agent " and " percipient," and that we have substituted for thought-reading the term thought-transference. Thought must here be taken as including more than it does in ordinary usage ; it must include sensations and volitions as well as mere repre- ssntations or ideas. This being understood, the name serves its purpose fairly well, as long as we are on experimental ground. It will not be for- gotten, however, that our aim is to connect an experimental with a spon- taneous class of cases ; and according to that view it will often be con- venient to describe the former no less than the latter as telepathic. We thus get what we need, a single generic term which embraces the whole Chap. II] THOUGHT-TRANSFERENCE 9 range of phenomena and brings out their continuity — the simpler experi- mental forms being the first step in a graduated series. § 2. The history of experimental thought-transference has been a singular one. It was not by direct trial, nor in what we should now account their normal form, that the phenomena first attracted the atten- tion of competent witnesses. Their appearance was connected with the discovery that the somnambulic state could be artificially induced. It was after the introduction of " mesmerism " or " magnetism " into France, and in the course of the investigation of that wider subject, that this special feature unexpectedly presented itself. The observations remained, it is true, extremely few and scattered. The greater part of them were made in this country, during the second quarter of the present [nineteenth] century ; and took the form of community of sensation be- tween the operator and the patient. The transference of impressions here depended on a specific rapport previously induced by mesmeric or hypnotic operations — passes, fixation, and the like. To us, now, this mesmeric rapport (in some, at any rate, of its manifestations) seems nothing more than the faculty of thought-transference confined to a single agent and percipient, and intensified in degree by the very conditions which limit its scope. But the course of discovery inverted the logical order of the phenomena. The recognition of the particular case, where the exercise of the faculty was narrowed down to a single channel, preceded by a long interval the recognition of the more general phenomena, as exhibited by persons in a normal state. The transference of impressions was naturally regarded as belonging essentially to mesmerism. As such, it was only one more wonder in a veritable wonderland ; and while obtaining on that account the readier acceptance among those W'lYio witnessed it, it to some extent shut out the idea of the possibility of similar manifestations where no specific rapport had been artificially established. But there was a further result. The early connection of thought- transference with mesmerism distinctly damaged its chance of scientific recognition. Those who believed in cognate marvels might easily believe in this marvel : but cautious minds rejected the whole posse of marvels together. And one can hardly wonder at this, when one remembers the wild and ignorant manner in which the claims of Mesmer and his followers were thrust upon the world. A man who professed to have magnetised the sun could hardly expect a serious hearing ; and even the operators who eschewed such extravagant pretensions still too often advocated their cause in a language that could only cover it with contempt. Theories of " odylic " force, and of imponderable fluids pervading the body — as dogmatically set forth as if they ranked in certainty with the doctrine of the circulation of the blood — were not likely to attract scientific inquiry to the facts. And in the later developments of hypnotism — in which many of the old " mesmeric " phenomena have been restudied from a truer point of view, and rapport of a certain sort betv/een the hypnotist and the " subject " has been admitted — there has been so much to absorb ob- servation in the extraordinary range of mental and physical effects which the operator can command by verbal or visible suggestion, that the far rarer telepathic phenomena have, so to speak, been crowded lo THE EXPERIMENTAL BASIS: [Chap. II out.i The consequence is that after nearly a century of controversy, the most interesting facts of mesmeric history are quite as Httle recognised as the less specialised kinds of thought-transference, which have only within the last few years been seriously looked for or definitely obtained. Some of the older cases referred to will be found quoted in extenso in the first chapter of the Supplement [not here reproduced]. Though recorded for the most part in a fragmentary and unsatisfactory way, it will be seen that they do not lack good, or even high, scientific authority. The testimony of Mr. Esdaile, for many years Presidency Surgeon in Calcutta, cannot be despised by any instructed physiologist in our day ; inasmuch as his work is now recognised as one of the most important contributions ever made to the rapidly-growing science of hypnotism. No one has denied the ability and integrity of Dr. Elliotson, nor (in spite of his speculative extravagances) of Reichenbach — who both witnessed instances of hypnotic telepathy. And though Professor Gregory, Dr. Mayo, the Rev. C. H. Townsend, and others, may not have been men of acute scientific intelligence, they were probably competent to conduct, and to record with accuracy, experiments the conditions of which involved no more than common care and honesty. We cannot but account it strange that such items of testimony as these men supplied should have been neglected, even by those who were most repelled by the ignorance and fanaticism which infected a large amount of the mesmeric literature. But since such was the fact, the observations will hardly now make their weight felt, except in connection with the fuller testimony of a more recent date. It is characteristic of every subject v.'hich depends on ques- tions of fact, and which has yet failed to win a secure place in intelligent opinion, that any further advance must for the most part depend on con- temporary evidence. I may, therefore, pass at once to the wholly new departure in thought-transference which the last few years have witnessed. § 3. The novelty of this departure — as has been already intimated — consists in the fact that successful results have been obtained when the percipient was apparently in a perfectly normal state, and had been subjected to no mesmerising or hypnotising process. The dawn of the discovery must be referred to the years 1875 and 1876. It was in the autumn of the latter year that our colleague. Professor W. F. Barrett [now Sir William Barrett] brought under the notice of the British Associa- tion, at Glasgow, a cautious statement of some remarkable facts which he had encountered, and a suggestion of the expediency of ascertaining how far recognised physiological laws would account for them. The facts themselves were connected with mesmerism ;* but the discussion ^ I refer specially to the eminent group of hypnotists at Nancy — Dr. Liebeault, and Professors Beaunis, Bernheim, and Liegeois. Dr. Liebeault has, however, personally described to us several instances of apparently telepathic transference which he has encountered in the course of his professional experience ; and some observations recorded by Professor Beaunis (in his admirable article on hypnotism in the Revue Philosophique for August, 1885, p. 12G), at any rate point, as he admits, to a new mode of sensibility. And since the above remarks were written, both these gentlemen have made definite experiments in telepathy, some of the resuhs of vrhich will be found [quoted in the original edition]. - Proceedings of the Society for Psychical Research, vol. i., pp. 241-2. Chap. II] THOUGHT-TRANSFERENCE ii in the Press to which the paper gave rise led to a considerable correspond- ence, in which Professor Barrett found his first hints of a faculty of thought- transference existing independently of the specific mesmeric rapport. That these hints happened to be forthcoming, just at the right m^oment, was a piece of great good fortune, and was due primarily to a circumstance quite unconnected with science, and from which serious results would scarcely have been anticipated — the invention of the " willing-game." In some form or other this pastime is probably familiar to most of my readers, either through personal trials or through the exhibitions of plat- form performers. The ordinary process is this. A member of the party, who is to act as " thought-reader," or percipient, leaves the room ; the rest determine on some simple action v/hich he, or she, is to perform, or hide some object which he is to find. The would-be percipient is then recalled, and his hand is taken or his shoulders are lightly touched by one or more of the willers. Under these conditions the action is often quickly performed or the object found. Nothing could at first sight look less like a promising starting-point for a new branch of inquiry. The " wilier " usually asserts, with perfect good faith, and often perhaps quite correctly, that he did not push ; but so little is it necessary for the guiding im- pression to be a push that it may be the very reverse — a slight release of tension when the " willed " performer, after various minute indications of a tendency to move in this, that, or the other wrong direction, at last hits on the right one. Even v/hen the utmost care is used to maintain the light contact with absolute neutrality, it is impossible to lay down the limits of any given subject's sensibilit5^ to such slight tactile and muscular hints. The experiments of Drs. Carpenter and Beard, and especially those of a member of our own Society, the Rev. E. H. Sugden, of Bradford, 1 and other unpublished ones on which we can rely, have shown us that the difference between one person and another in this respect is very great, and that with some organisations a variation of pressure so slight that the supposed " wilier " may be quite unaware of exercising it, but which he applies according as the movements of the other person are on the right track or not, may afford a kind of yes or no indication quite sufficient for a clue. This, indeed, is the one direct piece of instruc- tion which the game has supplied. We might perhaps have been to some extent prepared for the result b}^ observing the infinitesimal touches to which a horse v/ill respond, or the extremely slight indications on which we ourselves often act in ordinary life. But till this game was played, probably no one fully realised that muscular hints, so slight as to be quite unconsciously given, could be equally unconsciously taken ; and that thus a definite course of action might be produced without the faintest idea of guidance on either side. In some cases it appeared that even contact could be dispensed with, and the guidance was presumably of an auditory kind — the " subject " extracting from the mere footsteps of the " wilier," who was following him about, hints of satisfaction or dissatisfaction at the course he was taking.* But though this remarkable susceptibility to a particular order of impressions %vas an interesting dis- ^ Proceedings of the S.P.B., vol. i., p. 291 ; vol. ii., p. 11. ^ See the record of Mr. A. E. Outerbridge's experiments, published by Dr. Beard in the American Popular Science Monthly for July, 1877. 12 THE EXPERIMENTAL BASIS : [Chap. II covery, the results which could be thus explained clearly involved nothing new in kind. That recognised faculties may exhibit unsuspected degrees of refinement is a common enough conception. The more important point was that there were certain results which, apparently, could not be thus explained, at any rate, in any off-hand way. Occasionally the actions required of the " willed " performer were of so complicated a sort, and so rapidly carried out, as to cast considerable doubt on the adequacy of any muscular hints to evoke and guide them. Here, then, was the first indication of something new — of a hitherto unrecognised faculty ; and by good fortune, as I have said, Professor Barrett's appeal for further evidence as to transferred impressions came just at the time when the game had obtained a certain amount of popularity, and when its more delicate and unaccountable phenomena had attracted attention. Meanwhile similar observations were being made in America. America, indeed, was the original home of the " willing " entertainment ; and it is to an American, Dr. McGraw, that the credit belongs of having been the first (as far as I am aware) to detect in it the possible germ of some- thing new to science. In the Detroit Review of Medicine for August, 1875, Dr. McGraw gave a clear account of the ordinary physiological process — " the perception by a trained operator of involuntary and unconscious muscular movements " ; and then proceeded as follows : — " It seemed to me that there were features in these exhibitions which could not be satisfactorily explained on the hypothesis of involuntary muscular action, for . . . we are required to believe a man could un- willingly, and in spite of himself, give information by unconscious and involuntary signs that he could not give under the same circumstances by voluntary and conscious action. ... It seems to me there is a hint towards the possibility of the nervous system of one individual being used by the active will of another to accomplish certain simple motions." But though there might be enough in the phenomena to justify cautious suggestions of this sort, the ground is at best very uncertain. Even where some nicety of selection is involved, as, for instance, when a par- ticular note is to be struck on the piano, or a particular book to be taken out of a shelf, still, unless the subject's hand moves with extreme rapidity, it will be perfectly possible for an involuntary^ and unconscious indication to be given by the " wilier " at the instant that the right note or book is reached. In reports of such cases it is sometimes stated that there was no tentative process, and that the " subject's " hand seemed to obey the other person's will with almost the same directness as that person's own hand would have done. But this is a question of degree as to which the confidence of an eye-witness cannot easily be imparted to others. It may be worth while, however, to give an instance of a less common type by which the theory of muscular guidance does undoubtedly seem to be somewhat strained. The case was observed by Mr. Myers on October 31st, 1877. The performers were two sisters. " I wrote the letters of the alphabet on scraps of paper. I then thought of the word CLARA and showed it to M. behind R.'s back, R. Chap. II] THOUGHT-TRANSFERENCE 13 sitting at the table. M. put her hands on R.'s shoulders, and R. with shut eyes picked out the letters C L A R V — taking the V apparently for a second A, which was not in the pack — and laid them in a heap. She did not know, she said, what letters she had selected. No impulse had consciously passed through her mind, only she had felt her hands impelled to pick up certain bits of paper. " This was a good case as apparently excluding pushing. The scraps were in a confused heap in front of R., who kept still further confusing them, picking them up and letting them drop with great rapidity. M.'s hands remained apparently motionless on R.'s shoulders, and one can hardly conceive that indications could be given by pressure, from the rapid and snatching manner in which R. collected the right letters, touching several letters in the course of a second. M., however, told me that it was always necessary that she, M., should see the letters which R. was to pick up." Such a case may not suggest thought-transference, but it at any rate tempts one to look deeper than crude sensory signs for the springs of action, and to conceive the governance of one organism by another through some sort of nervous induction. It at any rate differs greatly in its con- ditions from the famous bank-note trick, where a number is written on a board, so slowly, and in figures of so large a size, that at every point the " wilier " may mark his opinion of the direction the lines are taking by involuntary muscular hints. It would be useless to accumulate further instances. The best of them could never be wholly conclusive, and mere multiplication adds nothing to their weight. By some of them, as I have said, the theory of muscular guidance is undoubtedly strained. But then the theory of muscular guidance ought to be strained, and strained to the very utmost, before being declared inadequate ; and it would always be a matter of opinion whether the point of " utmost " strain had been overpassed. Dr. McGraw and Professor Barrett surmised that it had ; Dr. Beard, of New York, was confident that it had not. The contention between " mind-reading " and " muscle-reading " could never reach a definite issue on this ground. But meanwhile the confident and exclusive adherents of the muscular hypothesis had a position of decided advantage over the doubters, for they could fairly enough represent themselves as the champions of science in its war with popular superstitions. The popular imagination more siio had fastened on the phenomena en bloc, and had decided that they were what they seemed to be — " thought-reading." To the average sightseer a mysterious word is far more congenial than a physiological explanation ; and it was, of course, the interest of the professional ex- hibitor to adopt and advertise a description which seemed to invest him with novel and magical powers. What more natural, therefore, than that those who saw the absurdity of these pretensions should regard further inquiry or suspension of judgment as a concession to ignorant credulity ? " Irving Bishop," it seemed fair to argue, " is a professed ' thought- reader ' ; Irving Bishop's tricks are, at best, mere feats of muscular and tactile sensibility ; ergo whoever believes that there is such a thing as ' thought-reading ' is on a par with the crowd who are mystified by Irving Bishop." 14 THE EXPERIMENTAL BASIS : [Chap. IT § 4. If, then, the ground of experiment had remained unchanged — if the old " wilhng-game " had merely continued to appear in various forms — no definite advance could have been made. But on the path of the old experiments, a quite new phenomenon now presented itself, which no one could have confidently anticipated, but for which the sug- gestions drav/n from the most advanced phenomena of the " willing- game " had to some extent prepared the way. It was discovered that not only transferences of impression could take place without contact, but that there was no necessity for the result aimed at to involve movements ; the fact of the transference might be shown, not — as in the " wdlling- game " — by the subject's ability to do something, but by his ability to discern and describe an object thought of by the " wilier." Both parties could thus remain perfectly still ; which was really a more important condition than even the absence of contact. In this form of experiment, muscle-reading and all the subtler forms of unconscious guidance are completely excluded ; and the dangers which remain are such as can, with sufficient care, be clearly defined and safely guarded against. In- dications of a visual kind — for instance, by the involuntary direction of glances — have no scope if the object which the percipient is to name is not present or visible in the room. There is, of course, an obvious danger in low whispering, or even soundless movements of the lips ; while the faintest accent of approval or disapproval in question or comment may give a hint as to whether the effort is tending in the right direction, and thus guide to the mark by successive approximations. Any exhibition of the kind before a promiscuous company is nearly sure to be vitiated by the latter source of error. But when the experiments are carried on in a limited circle of persons known to each other, and amenable to scientific control, it is not hard for those engaged to set a watch on their own and on each other's lips ; and questions and comments can be entirely for- bidden. I have been speaking of the danger of involuntary guidance. There is, of course, another danger to be considered — that of voluntary guidance — of actual collusion betv/een the agent and percipient. Contact being excluded, such guidance would have to be by signals ; and it is impos- sible to lay down any precise limit to" the degree of perfection that a plan of signalling may reach. The long and short signs of the Morse code admit of many varieties of application ; and though the channels of sight and touch may be cut off, it is difficult entirely to cut off that of hearing. Shufflings of the feet, coughs, irregularities of breathing, all offer available material. But though the precise line of possibilities in this direction cannot be drawn, we are at any rate able to suggest cases where the line would be clearly overpassed. For instance, if the idea to be transferred from the agent to the percipient is inexpressible in less than twenty words ; and if hearing is the only sensory channel left open ; and if it is carefully observed that there are no coughs or shufflings, and that the agent's breathing appears regular, then one seems justified in saying that the necessary information could not be conveyed by a code without a very considerable expenditure of time, and a very abnormally acute sense of hearing on the percipient's part. There is no relation whatever between a private experiment performed under such conditions as these, Chap. II] THOUGHT-TRANSFERENCE 15 and the feats of a conjurer, like Mr. Maskelyne, who commands secret apparatus, and whose every word and gesture ma}^ be observed and interpreted by a concealed confederate. It would be rash, however, to represent as crucial any apparent trans- ferences of thought between persons not absolutely separated, where the good faith of at least one of the two is not accepted as beyond question, and where the genuineness of the result is left to depend on the perfection with v/hich third parties have arranged conditions and guarded against signs. The conditions of a crucial result, for one's own mind, are either (i) that the agent or the percipient shall be oneself ; or (2) that the agent or percipient shall be someone whose experience, as recorded by himself, is indistinguishable in certainty from one's own ; or (3) that there shall be several agents or percipients, in the case of each of whom the improbability of deceit, or of such imbecility as would take the place of deceit, is so great that the combination of improbabilities amounts to a moral im- possibility. The third mode of attaining conviction is the most practically important. For it is not to be expected of most people that, within a short time, they will either themselves be, or have intimate friends who are, successful agents or percipients ; and they are justified, therefore, in demanding that the evidence to which they might fairly refuse credence if it depended on the veracity and intelligence of one or two persons, of however unblemished a reputation, shall be multiplied for their benefit. Whatever be the experimenter's assurance as to the perfection of his conditions, it is in the nature of things impossible that strangers, who only read and have not seen, should be infected by it. They cannot be absolutely certain that this, that, or the other stick might not break ; then enough sticks must be collected and tied together to make a faggot of a strength which shall defy suspicion.^ As regards the experiments of which I am about to present a sketch, it is not necessary to my argu- ment that any individual's honesty shall be completely assumed, in the sense of being used as a certain basis for conclusions. The proof must ^ In reference to the objection that the demand for quantity of evidence shov;s that we know the quality of each item to be bad, I may quote the following passage from a presidential address of Professor Sidgwick's : " The quality of much of cur evidence — when considered apart from the strangeness of the matters to which it refers — is not bad, but very good : it is such that one or two items of it would be held to establish the occurrence, at any particular time and place, of any phenomenon whose existence was generally accepted. Since, however, on this subject the best single testimony only yields a.n improbability of the testimony heing false that is outweighed by the improbability of the fact heing true, the only way to make the scale fall on the side of the testimony is to increase the quantity. If the testimony were not good, this increase of quantity would be of little value ; but if it is such that the hypothesis of its falsity requires us to suppose abnormal motiveless deceit, or abnormal stupidity or carelessness, in a person hitherto reputed honest and intelligent, then an increase in the number of cases in which such a supposition is required adds importantly to the improbability of the general hypothesis. It is sometimes said by loose thinkers that the ' moral factor ' ought not to come in at all. But the least reflection shows that the moral factor must come in in all the reasonings of experimental science, except for those who have personally repeated all the experiments on which their conclusions are based. Any one who accepts the report of the experiments of another must rely, not only on his intelligence, but on his honesty : only ordinarily his honesty is so completely assumed that the assumption is not noticed." t6 the experimental basis : [Chap. I depend on the number of persons, reputed honest and inteUigent, to whom dishonesty or imbeciUty must be attributed if the conclusions are wrong, i.e., it must be a cumulative proof. Not that my colleagues and I have any doubt as to the bona fides of every case here recorded. But even where our grounds of certainty are most obvious, they cannot be made entirely obvious to those to whom we and our more intimate associates are personally unknown ; while outside this inner circle our confidence depends on points that can scarcely even be suggested to others — on views of character gradually built up out of a number of small and often indefinable items of conversation and demeanour. We may venture to say that a candid critic, present during the whole course of the experi- ments, would have carried away a far more vivid impression of their genuineness than any printed record can convey. But it must be dis- tinctly understood that we discriminate our cases ; and that even where the results are to our own minds crucial — in that they can only be im- pugned by impugning the honesty or sanity of members of our own investigating Committee — we do not demand their acceptance on this ground alone, or attempt accurately to define the number of reputations which should be staked before a fair mind ought to admit the proof as overwhelming. As observations are accumulated, different " fair minds " will give in at different points ; and until the most exacting are satisfied, our task will be incomplete. § 5. I mentioned above the correspondence which followed Professor Barrett's appeal for evidence. In this correspondence, among many instances of the higher aspects of the " willing-game," there was a small residue which pointed to a genuine transference of impression without contact or movement. Of this residue the most important item was that supplied by our friend, the Rev. A. M. Creery, then resident at Buxton, and now working in the diocese of Manchester. He had his attention called to the subject in October, 1880 ; and was early struck by the impossibility of deciding, in cases where contact was employed, how far the powers of unconscious muscular guidance might extend. He, there- fore, instituted experiments with his daughters and with a young maid- servant, in which contact was altogether eschewed. He thus describes the early trials : — " Each went out of the room in turn, while I and the others fixed on some object which the absent one was to name on returning to the room. After a few trials the successes preponderated so much over the failures that we were all convinced there was something very wonderful coming under our notice. Night after night, for several raonths, we spent an hour or two each evening in varying the conditions of the experiments, and choosing new subjects for thought-transference. We began by selecting the simplest objects in the room ; then chose names of towns, names of people, dates, cards out of a pack, lines from different poems, &c., in fact any things or series of ideas that those present could keep steadily before their minds ; and when the children were in good humour, and excited by the wonderful nature of their successful guessing, they very seldom made a mistake. I have seen seventeen cards, chosen by myself, named right in succession, without any mistake. We soon found that a Chap. II] THOUGHT-TRANSFERENCE 17 great deal depended on the steadiness with which the ideas were kept before the minds of ' the thinkers,' and upon the energy with which they willed the ideas to pass. Our worst experiments before strangers have invariably been when the company was dull and undemonstrative ; and we are all convinced that when mistakes are made, the fault rests, for the most part, with the thinkers, rather than with the thought-readers." In the course of the 5-ears 1881 and 1882, a large number of experi- ments were made with the Creery family, first by Professor Barrett, then by Mr. and Mrs. Sidgwick, by Professor Balfour Stewart, f.r.s., and Professor Alfred Hopkinson, of Owens College, Manchester, and, after the formation of the Society for Psychical Research, by the Thought-" transference Committee of that body, of which Mr. Myers and myself were members. The children in turn acted as " percipients," the other persons present being " agents," i.e., concentrating their minds on the idea of some selected word or thing, with the intention that this idea should be transferred to the percipient's mind. The thing selected was either a card, taken at random from a full pack ; or a name chosen also at random ; or a number, usually of two figures ; or occasionally some domestic implement or other object in the house. The percipient was, of course, absent when the selection was made, and when recalled had no means of discovering through the exercise of the senses what it was, unless by signals, consciously or unconsciously given by one or other of the agents. Strict silence was maintained throughout each experiment, and when the group of agents included any members of the Creery family, the closest watch was kept in order to detect any passage of signals ; but in hundreds of trials nothing was observed which suggested any attempt of the sort. Still, such simple objects would not demand an elaborate code for their description ; nor were any effective means taken to block the percipient's channels of sense — it being thought expedient in these early trials not to disturb their minds by obtrusive precautions. We could not, therefore, regard the testimony of the investigators present as adding much weight to the experiments in which any members of the family were among the group of agents, unless the percipient was completely isolated from that group. Such a case was the following : — " Easter, 1881. Present : Mr. and Mrs. Creery and family, and W. F. Barrett, the narrator. One of the children was sent into an adjoining room, the door of which I saw was closed. On returning to the sitting- room and closing its door also, I thought of some object in the house, fixed upon at random ; writing the name down, I showed it to the family present, the strictest silence being preserved throughout. We then all silently thought of the name of the thing selected. In a few seconds the door of the adjoining room was heard to open, and after a very short interval the child would enter the sitting-room, generally with the object selected. No one was allowed to leave the sitting-room after the object had been fixed upon ; no communication with the child was conceivable, as her place was often changed. Further, the only instructions given to the child were to fetch some object in the house that I would fix upon, and, together with the family, silently keep in mind, to the exclusion, as far as possible, of all other ideas. In this way I wrote down, among other things, a hair-bntsh ; it was brought : an orange ; it was brought : i8 THE EXPERIMENTAL BASIS : [Chap. II a wine-glass ; it was brought : an apple ; it was brought : a ioastwg-fork ; failed on the first attempt, a pair of tongs being brought, but on a second trial it was brought. With another child (among other trials not here mentioned) a citp was written down by me ; it was brought : a saucer ; this was a failure, a plate being brought ; no second trial allowed. The child being told it was a saucer, replied, ' That came into my head, but I hesitated as I thought it unlikely you would name saucer after cup, as being too easy.' " But, of course, the most satisfactory condition was that only the members of the investigating Committee should act as agents, so that signals could not possibly be given unless by one of them. This condition clearly makes it idle to represent the means by which the transferences took place as simply a trick which the members of the investigating Com- mittee failed to detect. The trick, if trick there was, must have been one in which the}^ or one of them, actively shared ; the only alternative to collusion on their part being some piece of carelessness amounting almost to idiocy — such as uttering the required word aloud, or leaving the selected card exposed on the table. The following series of experiments was made on April 13th, 1882. The agents were Mr. Myers and the present writer, and two ladies of their acquaintance, the Misses Mason, of Morton Hall, Retford, who had become interested in the subject by the remarkable successes which one of them had obtained in experimenting among friends. ^ As neither of these ladies had ever seen any member of the Creery family till just before the experiments began, they had no opportunities for arranging a code of signals with the children ; so that any hypothesis of collusion must in this case be confined to Mr. Myers or the present writer. As regards the hypothesis of ivant of intelligence , the degree of intelligent behaviour required of each of the four agents was simply this : (i) To keep silence on a particular subject ; and (2) to avoid un- consciously displaying a particular card or piece of paper to a person situated at some yards' distance. The first condition was realised by keeping silence altogether ; the second by remaining quite still. The four observers were perfectly satisfied that the children had no means at any moment of seeing, either directly or by reflection, the selected card or the name of the selected object. The following is the list of trials : — Objects to be named. (These objects had been brought, and still remained, in the pocket of one of the visitors. The name of the object selected for trial was secretly written down, not spoken.) A White Penknife. — Correctly named, with the colour, the first trial. Box of Almonds. — Correctlj' named. Threepenny piece. — Failed. Box of Chocolate. — Button -box said ; no second trial given. (A penknife was then hidden ; but the place was not discovered.) Numbers to be named. Five. — Rightly given on the first trial. Fourteen . — Failed . ^ See Miss Mason's interesting paper on the subject in Macmillnn's Magazine iov October, 1882. Chap.

Three of hearts. — Right first time. Five of clubs. — Failed. Ace of spades. — Failed. The chances against accidental success in the case of any one card are, of course, 51 to i ; yet out olfotirteen successive trials nine were successful at the first guess, and only three trials can be said to have been complete failures. The odds against the occurrence of the five successes running, in the card series, are considerably over 1,000,000 to i. On none of these occasions was it even remotely possible for the child to obtain by any ordinary means a knowledge of the object selected. Our own facial expression was the only index open to her ; and even if we had not pur- posely looked as neutral as possible, it is difficult to imagine how we could have unconsciously carried, say, the two of diamonds written on our foreheads. During the ensuing year, the Committee, consisting of Professor Barrett, Mr. Myers, and the present writer, made a number of experi- ments under similar conditions, which excluded contact and movement, and which confined the knowledge of the selected object — and, therefore, the chance of collusion with the percipient — to their own group. In some of these trials, conducted at Cambridge, Mrs. F. W. H. Myers and Miss Mason also took part. In a long series conducted at Dublin, Professor Barrett was alone with the percipient. Altogether these scrupulously guarded trials amounted to 497 ; and of this number 95 were completely successful at the first guess, and 45 at the second. The results may be clearer if arranged in a tabular form. 20 THE EXPERIMENTAL BASIS [Chap. II H 1^ >— , () m O H O w s s k) o W«J rn w 12; H 2 y H W m ^ > Q 1— 1 W ^; «i!

Y. Edgeworth, to whom these results were submitted, and who calculated the final column of the Table, has kindly appended the following remarks : — " These observations constitute a chain or rather coil of evidence, which at first sight and upon a general view is seen to be very strong, but of which the full strength cannot be appreciated until the concatena- tion of the parts is considered. " Viewed as a whole the Table presents the following data. There are in all 497 trials. Out of these there are 95 successes at the first guess. The number of successes most probable on the hypothesis of mere chance is 27. The problem is one of the class which I have discussed in the Proceedings of the S.P.R., Vol. III., p. 190, &c. The approxi- mative formula there given is not well suited to the present case,^ in which the number of successes is very great, the probability of their being due to mere chance very small, in relation to the total number of trials. It is better to proceed directly according to the method employed in the paper referred to (p. 198) for the appreciation of M. Richet's result EPJYEIOD [see below, p. 60]. By this method, ^ with the aid of appropriate tables,'' I find for the probability that the observed total of successes have resulted from some other agency than pure chance ■999, 999, 999, 999, 999, 999, 999, 999, 98 " Stupendous as is this probability it falls short of that which the complete solution of our problem yields. For, measuring and joining all the links of evidence according to the methods described in the paper refen'ed to, I obtain a row of thirty-four nines following a decimal point. A fortiori, if we take account of the second guesses. " These figures more impressively than any words proclaim the certainty that the recorded observations must have resulted either from collusion on the part of those concerned (the hypothesis of illusion being excluded by the simplicity of the experiments), or from thought-transference of the sort which the investigators vindicate." A large number of trials were also made in which the group of agents included one or more of the Creery family ; and as bearing on the hypo- thesis of an ingenious family trick, it is worth noting that — except where Mr. Creery himself was thus included — the percentage of successes was, as a rule, not appreciably higher under these conditions than when the Committee alone were in the secret. When Mr. Creery was among the agents, the average of success was far higher ; but his position in the affair was precisely the same as our own ; and the most remarkable results were obtained while he was himself still in a state of doubt as to the genuine- ness of the phenomena which he was investigating. One further evidential point should be noted. Supposing such a thing as a genuine faculty of thought-transference to exist, and to be capable, for example, of evoking in one mind the idea of a card on which other minds are concentrated, we might naturally expect that the card-pictures conveyed to the percipient would present various degrees of distinctness, ^ The formula is adequate to prove that an inferior limit of the sought probability is -9999. " Owing to the rapid convergency of the series which we have to sum, it will be found sufficient to evaluate two or three terms. * Tables of Logarithms, and of the values of log V {x-^ 1). 22 THE EXPERIMENTAL BASIS : [Chap. II and that there would be a considerable number of approximate guesses, as they might be given by a person who was allowed one fleeting glimpse at a card in an imperfect light. Such a person might often fail to name the card correctly, but his failures would be apt to be far more nearly right than those of another person who was simply guessing without any sort of guidance. This expectation was abundantly confirmed in our experiments. Thus, in a series of 32 trials, where only 5 first guesses were completely right, the suit was 14 times running named correctly on the first trial, and reiterated on the second. Knave was very frequently guessed as King, and vice versa, the suit being given correctly. The number of pips named was in many cases only one off the right number, this sort of failure being specially frequent when the number was over six. Again, the correct answer was often given, as it were, piecemeal — in two partially incorrect guesses — the pips or picture being rightly given at the first attempt, and the suit at the second ; and in the same way with numbers of two figures, one of them would appear in the first guess and the other in the second. Before we leave these early experiments, one interesting question presents itself, which has an important bearing on the wider subject of this book. In what form was the impression flashed on the percipient's mind ? What were the respective parts in the phenoinena played by the mental eye and the mental ear ? The points just noticed in connection with the partial guessing of cards seem distinctly in favour of the mental eye. A king looks like a knave, but the names have no similarity. So with numbers. 35 is guessed piecemeal, the answers being 45 and 43 ; so 57 is attempted as 47 and 45. Now the similarity in sound between three and thirty in 43 and 35, or between five and fifty in 45 and 57, is not extremely strong ; while the pichire of the 3 or the 5 is identical in either pair. On the other hand, names of approximate sound were often given instead of the true ones ; as " Chester "for Leicester, " Biggis " for Billings, " Freemore " for Frogmore. Snelgrove was reproduced as " Singrore " ; the last part of the name was soon given as " Grover," and the attempt was then abandoned — the child remarking afterwards that she thought of " Snail " as the first syllable, but it had seemed to her too ridiculous. Professor Barrett, moreover, sx:ccessfully obtained a German word of which the percipient could have formed no visual image. 1 The children's own account was usually to the effect that they " seemed to see " the thing ; but this, perhaps, does not come to much ; as a known object, however suggested, is likel}^ to be instantly visualised. On the whole, then, the conclusion seems to be that, with these " subjects," both modes of transference were possible ; and that they prevailed in turn, according as this or that was better adapted to the particular case. §6.1 have dwelt at some length on our series of trials with the members of the Creery family, as it is to those trials that we owe our own conviction of the possibility of genuine thought-transference between persons in a normal state. I have sufficiently explained that we do not expect the ' In an account of some experiments with words, which we have received from a correspondent, it is stated that success was decidedly more marked in cases where there was a broad vowel sound. Chap. II] THOUGHT-TRANSFERENCE 23 results to be as crucial for persons who were not present, and to whom we are ourselves unknown, as they were for us ; and that it cannot be " in the mouth of two or three witnesses " only that such a stupendous fact as the transmission of ideas otherwise than through the recognised sensory channels will be established. The testimony must be multiplied ; the responsibility must be spread ; and I shall immediately proceed to describe further results obtained with other agents and other percipients. But first it may perhaps be asked of us why we did not exploiter this remarkable family further. It was certainly our intention to do what we could in this direction, and by degrees to procure for our friends an opportunity^ of judging for themselves. This point, however, was one which could only be cautiously pressed. Mr. Creery v/as certainly justified in regarding his daughters as something more than mere subjects of ex- periments, and in hesitating to make a show of them to persons who might, or rather who reasonably must, begin by entertaining grave doubts as to their good faith. It must be remembered that we were dealing, not with chemical substances, but with youthful minds, liable to be reduced to confusion by anything in the demeanour of visitors which inspired distaste or alarm ; and even with the best intentions, " a childly way with children " is not easy to adopt where the children concerned are objects of suspicious curiosity. More especially might these considera- tions have weight, when failure was anticipated for the first attempts made under new conditions. And this suggests another difficulty, which has more than once recurred in the experimental branches of our work. The would-be spectators themselves may be unable or unwilling to fulfil the necessary conditions. Before introducing them, it is indispensable to obtain some guarantee that they on their part will exercise patience, make repeated trials, and give the " subjects " a fair opportunity of getting used to their presence. Questions of mood, of goodwill, of familiarity, may hold the same place in psychical investigation as questions of tem- perature in a physical laboratory ; and till this is fully realised, it will not be easy to multiply testimony to the extent that we should desire. In the case of the Creery family, however, we met with a difficulty of another kind. Had the faculty of whose existence we assured our- selves continued in full force, it would doubtless have been possible in time to bring the phenomena under the notice of a sufficient number of painstaking and impartial observers. But the faculty did not continue in full force ; on the contrary, the average of successes gradually declined, and the children regretfully acknowledged that their capacity and con- fidence were deserting them. The decline was equally observed even in the trials which they held amongst themselves ; and it had nothing Vv-hat- ever to do with any increased stringency in the precautions adopted. No precautions, indeed, could be stricter than that confinement to our own investigating group of the knowledge of the idea to be transferred, which was, from the very first, a condition of the experiments on which we absolutely relied. The fact has just to be accepted, as an illustration of the fleeting character which seems to attach to this and other forms of abnormal sensitiveness. It seem,s probable that the telepathic faculty, if I may so name it, is not an inborn, or lifelong possession ; or, at any rate, that ver^^ slight disturbances may suffice to paralyse it. The Creerj^s 24 THE EXPERIMENTAL BASIS [Chap. Il had their most startHng successes at first, when the affair was a surprise and an amusement, or later, at short and seemingly casual trials ; the decline set in with their sense that the experiments had become matters of weighty importance to us, and of somewhat prolonged strain and tediousness to them.^ So, on a minor scale, in trials among our own friends, we have seen a fortunate evening, when the spectators were interested and the percipient excited and confident, succeeded by a series of failures when the results were more anxiously awaited. It is almost inevitable that a percipient who has aroused interest by a marked success on several occasions, should feel in a way responsible for further results ; and yet any real preoccupation with such an idea seems likely to be fatal. The conditions are clearly unstable. But of course the first question for science is not whether the phenomena can be produced to order, but whether in a sufficient number of series the proportion of success to failure is markedly' above the result of chance. § 7. Before leaving this class of experiments, I may mention an interesting development which it has lately received. In the Revue Philosophique for December, 1884, M. Ch. Richet, the well-known savant and editor of the Revue Scientifique, published a paper, entitled " La Suggestion Mentale et le Calcul des Probabilit^s," in the first part of which an account is given of some experiments v/ith cards precisely similar in plan to those above described. A card being drawn at random out of a pack, the " agent " fixed his attention on it, and the " percipient " en- deavoured to name it. But M. Richet's method contained this important novelty — that though the success, as judged by the results of any particular series of trials, seemed slight (showing that he was not experimenting with what we should consider " good subjects "), he made the trials on a sufficiently extended scale to bring out the fact that the right guesses were on the whole, though not strikingly, above the number that pure accident would account for, and that their total was considerably above that number. This observation involves a new and striking application of the calculus of probabilities. Advantage is taken of the fact that the larger the number of trials made under conditions where success is purely accidental, the more nearly will the total number of successes attained conform to the figure which the formula of probabilities gives. For instance, if some one draws a card at random out of a full pack, and before it has been looked at by anyone present I make a guess at its suit, my chance of being right is, of course, i in 4. Similarly, if the process is repeated 52 times, the most probable number of successes, according to the strict calculus of prob- ^ [Subsequently to the publication of Phantasms of the Living, in a series of experi- ments with cards, two of the sisters acting as " agent " and " percipient " were detected in the use of a code of signals, and a third confessed to a certain amount of signalling in earlier series. An account of this discovery will be found in Proceedings of the Society for Psychical Research, vol. v., pp. 269-270. It of course makes it impossible to rely on experiments with this family in which signalling can have been made use of, but it is dithcult to see how it can have operated when, as in the cases quoted above, " agency " was confined to the investigatmg committee. Still, these experiments woukl not, I thurk, have been given a place in the book had the dis- coveiy been made before publication. See beloAv p. 61. — Ed.] Chap. 11] THOUGHT-TRANSFERENCE 25 abilities, is 13 ; in 520 trials the most probable number of successes is^i3o. Now, if we consider only a short series of 52 guesses, I may be accidentally right many more times than 13 or many less times. But if the series be prolonged — if 520 guesses be allowed instead of 52 — the actual number of successes will vary from the probable number within much smaller limits ; and if we suppose an indefinite prolongation, the proportional divergence between the actual and the probable number will become infinitely small. This being so, it is clear that if, in a very short series of trials, we find a considerable difference between the actual number of successes and the probable number, there is no reason for regarding this difference as anything but purely accidental ; but if we find a similar difierence in a very long series, we are justified in surmising that some condition beyond mere accident has been at work. If cards be drawn in succession from a pack, and I guess the suit rightly in 3 out of 4 trials, I shall be foolish to be surprised ; but if I guess the suit rightly in 3,000 out of 4,000 trials, I shall be equally foolish not to be surprised. Now M. Richet continued his trials until he had obtained a consider- able total ; and the results were such as at any rate to suggest that accident had not ruled undisturbed — that a guiding condition had been introduced, which affected in the right direction a certain small percentage of the guesses made. That condition, if it existed, could be nothing else than the fact that, prior to the guess being made, a person in the neighbourhood of the guesser had concentrated his attention on the card drawn. Hence the results, so far as they go, make for the reality of the faculty of " mental suggestion." The faculty, if present^ was clearly only slightly developed ; whence the necessity of experimenting on a very large scale before its genuine influence on the numbers could be even surmised. Out of 2,927 trials at guessing the suit of a card, drawn at random, and steadily looked at by another person, the actual number of suc- cesses was 789 ; the most probable number, had pure accident ruled, was 732. The total was made up of thirty-nine series of difierent lengths, in which eleven persons took part, M. Richet himself being in some cases the guesser, and in others the person who looked at the card. He observed that when a large number of trials were made at one sitting, the aptitude of both persons concerned seemed to be affected ; it became harder for the " agent " to visualise, and the proportion of successes on the guesser 's part decreased. If we agree to reject from the above total all the series in which over 100 trials were consecutively made, the numbers become more striking. ^ Out of 1,833 trials, he then got 510 successes, the most probable number being only 458 ; that is to say, the actual number exceeds the most probable number by about -J^-. Clearly no definite conclusion could be based on such figures as the above. They at most contained a hint for more extended trials, but a hint, fortunately, which can be easily followed up. We are often asked by acquaintances what they can do to aid the progress of psychical re- search. These experiments suggest a most convenient answer ; for they ^ It should be remarked, however, that the introduction of any principle of selection, after one experiment, is always objectionable. For some more or less plausible reason could probably always be found for setting aside the less favourable results. 26 THE EXPERIMENTAL BASIS : [Chap. II can be repeated, and a valuable contribution made to the great aggre- gate, by any two persons who have a pack of cards and a little perse- verance' Up to the time that I write, we have received, in all, the results of 17 batches of trials in the guessing of suits. In 11 of the batches one person acted as agent and another as percipient throughout : the other 6 batches are the collective results of trials made by as many groups of friends. The total number of trials was 17,653, and the total number of successes was 4,760 ; which exceeds by 347 the number which was the most probable if chance alone acted. The probability afforded by this result for the action of a cause other than chance is •999,999,999,1 — or practical certainty.- I need hardly say that there has been here no selection of results ; all who undertook the trials were specially re- quested to send in their report, whatever the degree of success or un- success ; and we have no reason to suppose that this direction has been ignored. It is thus an additional point of interest that in only one of the batches did the result fall heloiv the number which was the most probable one for mere chance to give. And if we take only those batches, 10 in number, in which a couple of experimenters made as many as 1,000 trials and over, the probability of a cause other than chance which the group of results yields is estimated by one method to be '999,999,999,96, and by another to be •999,999,999,999,2. To this record must be added another, not less striking, of experi- ments which (though part of the same effort to obtain large collective results) differed in form from the above, and could not, therefore, figure in the aggregate. Thus, in a set of 976 trials, carried out by Miss B. Lindsay (late of Girton College), and a group of friends, where the choice was between 6 tmcoloured forms — 9 specimens of each being combined in a pack from which the agent drew at random — the total of right guesses was 198, the odds against obtaining that degree of success by chance being about 500 to i. In another case, the choice lay between 4 things, but these were not suits, but simple colours — red, blue, green, and yellow. The percipient throughout was Mr. A. J. Shilton, of 40, Paradise Street, Birmingham ; the agent (except in one small group, when Professor Poynting, of Mason College, acted) was Mr. G. T. Cashmore, of Albert Road, Handsworth. Out of 505 trials, 261 were successes. The proba- bility here afforded of a cause other than chance is considerably more than a trillion trillions to i. And still more remarkable is the result obtained by the Misses Wingfield, of The Redings, Totteridge, in some trials where the object to be guessed was a number of two digits — i.e., one ' The rules to observe are these : (1) The number of trials contemplated (1,000, 2,000, or whatever it may be) should be specified beforehand. (2) Not more than 50 trials should be made on any one occasion. (3) The agent should draw the card at random, and cut the pack between each draw. (4) The success or failure of each guess should be silently recorded, and the percipient should be kept m ignorance of the results until the whole series is completed. [The results should be sent to the Secretary of the Society for Psychical Research, 20 Hanover Square, W.] '^ For these calculations we have again to thank Mr. F. Y. Edge worth. For an explanation of the methods employed, see his article m vol. iii. of the Proceedings of the S.P.R., already referred to, and also his paper on " Methods of Statistics" {sub fin.) in the Journal of the Statistical Society for 1885. Chap. II] THOUGHT-TRANSFERENCE 27 of the go numbers included in the series from 10 to 99 — chosen at random by the agent. Out of 2,624 trials, where the most probable number of successes was 29, the actual number obtained was no less than 275 — to say nothing of 78 other cases in which the right digits were guessed in the reverse order. In the last 506 trials the agent (who sat some 6 feet behind the percipient) drew the numbers at random out of a bowl ; the odds against the accidental occurrence of the degree of success — 21 right guesses — obtained in this batch are over 2,000,000 to i. The argument for thought-transference afforded by the total of 275 cannot be expressed here in figures, as it requires 167 nines — that is, the probability is far more than the ninth power of a trillion to i. Card-experiments of the above type offer special conveniences for the very extended trials which we wish to see carried out : they are easily made and rapidly recorded. At the same time it must not be a.ssumed that the limitation of the field of choice to a very small number of known objects is a favourable condition ; it is probably the reverse. For from the descriptions which intelligent percipients have given it would seem that the best condition is a sort of inward blankness, on which the image of the object, sometimes suddenly but often only gradu- ally, takes shape. And this inward blankness is hard to ensure when the objects for choice are both few and known. For their images are then apt to importune the mind, and to lead to guessing ; the little pro- cession of them marches so readily across the mental stage that it is difficult to drive it off, and wait for a single image to present itself inde- pendently. Moreover idiosyncrasies on the guessers' part have the op- portunity of obtruding themselves — as an inclination, or a disinclination, to repeat the same guess several times in succession. These objections of course reach their maximum if the field of choice be narrowed down to two things — as where not the suit but the colour of the cards is to be guessed. And in fact some French trials of this type, and an aggregate of 5,500 carried out by the American Society for Psychical Research, ^ give a result only very slightly in excess of the most probable number. § 8. I may now pass to another class of experiments, in which the impression transferred was almost certainly of the visual sort, inasmuch as any verbal description of the object would require a group of words too numerous to present any clear and compact auditory character. An object of this kind is supplied by any irregular figure or arrangement of lines which suggests nothing in particular. We have had two remark- ably successful series of experiments, extending over many days, in which ^ Report by Professors J. M. Peirce and E. C. Pickering, in the Proceedings of the American Society for Psychical Research, vol. i., p. 19. This Society has also carried out 12,130 trials with the 10 digits — which similarly gave a result only slightly in excess of theoretic probability. But here the digits to be thought of by the agent were not taken throughout in a purely accidental order, but in regularly recurring decads, in each of which each digit occurred once ; and consequently the later guesses (both within the same decad and in successive decads) might easily be biassed by the earlier ones. This system may lead to interesting statistics in other ways ; but to give thought-transference fair play in experiments with a limited number of objects, it seems essential that the order of selection shall be entirely haphazard, and that the guesser's mind shall be quite unembarrassed by the notion of a scheme. 28 THE EXPERIMENTAL BASIS : [Chap. II the idea of such a figure has been telepathically transferred from one mind to another. A rough diagram being first drawn by one of the in- vestigating Committee, the agent proceeded to concentrate his attention on it, or on the memory which he retained of it ; and in a period varying from a few seconds to a few minutes the percipient was able to reproduce the diagram, or a close approximation to it, on paper. No contact was permitted, except on a few occasions, which, on that very account, we should not present as crucial ; and m order to preclude the agent from giving unconscious hints — e.g., by drawing with his finger on the table or maldng movements suggestive of the figure in the air — he was kept out of the percipient's sight. Of the two series mentioned, the second is evidentially to be preferred. For in the first series the agent, as well as the percipient, was always the same person ; and we recognise this as pro tanto an objection. Not indeed that the simple hypothesis of collusion would at all meet the difficulties of the case. Faith in the power of a secret code must be carried to the verge of superstition, before it will be easy to believe that auditory signals, the material for which (as I pointed out above) is limited to the faintest variations in the signaller s method of breathing, can fully and faithfully describe a complicated diagram ; especially when the varia- tions, imperceptible to the closest observation of the bystanders, would have to penetrate to the intelligence of a percipient whose head was enveloped in bandage, bolster-case, and blanket. But in spite of all, suspicion will, reasonably or unreasonably, attach to results which are, so to speak, a monopoly of two particular performers. In our second series of experiments this objection was obviated. There were two per- cipients, and a considerable group of agents, each of whom, when alone with one or other of the percipients, was successful in transferring his impression. It is this series, therefore, that I select for fuller description. We owe these remarkable experiments to the sagacity and energy of Mr. Malcolm Guthrie, J. P., of Liverpool. At the beginning of 1883, Mr. Guthrie happened to read an article on thought-transference in a magazine, and though completely sceptical, he determined to make some trials on his own account. He was then at the head of an estab- lishment which gives employment to many hundreds of persons ; and he was informed by a relative who occupied a position of responsibility in this establishment that she had witnessed remarkable results in some casual trials made by a group of his employees after business hours. He at once took the matter into his own hands, and went steadily, but cau- tiously, to work. He restricted the practice of the novel accomplishment to weekly meetings ; and he arranged with his friend, Mr. James Birchall, the hon. secretary of the Liverpool Literary and Philosophical Society, that the latter should make a full and complete record of every experi- ment made. Mr. Guthrie thus describes the proceedings : — " I have had the advantage of studying a series of experiments ab ova. I have witnessed the genuine surprise which the operators and the ' subjects ' have alike exhibited at their increasing successes, and at the results of our excursions into novel lines of experiment. The affair has not been the discovery of the possession of special powers, first made and Chap. II] THOUGHT-TRANSFERENCE 29 then worked up by the parties themselves for gain or glory. The experi- menters in this case were disposed to pass the matter over altogether as one of no moment, and only put themselves at my disposal in regard to experiments in order to oblige me. The experiments have all been devised and conducted by myself and Mr. Birchall, without any previous intimation of their nature, and could not possibly have been foreseen. In fact they have been to the young ladies a succession of surprises. No set of experi- ments of a similar nature has ever been more completely known from its origin, or more completely under the control of the scientific observer." I must pass over the record of the earlier experiments, where the ideas transferred were of colours, geometrical figures, cards, and visible objects of all sorts, which the percipient was to name — these being similar in kind, though on the whole superior in the proportion of successes, to those already described.^ The reproduction of diagrams was introduced in October, 1883, and in that and the following month about 150 trials were made. The whole series has been carefully mounted and pre- served by Mr. Guthrie. • No one could look through them without per- ceiving that the hypothesis of chance or guess-work is out of the question ; that in most instances some idea, and in many a complete idea, of the original must, by whatever means, have been present in the mind of the person who made the reproduction. In Mr. Guthrie's words : — " It is difficult to classify them. A great number of them are decided successes ; another large number give part of the drawing ; others exhibit the general idea, and others again manifest a kind of composition of form. Others, such as the drawings of flowers, have been described and named, but have been too difficult to draw. A good many are perfect failures. The drawings generally run in lots. A number of successful copies will be produced very quickly, and again a number of failures — indicating, I think, faultiness on the part of the agent, or growing fatigue on the part of the ' subject.' Every experiment, whether successful or a failure, is given in the order of trial, with the conditions, name of ' subject ' and agent, and any remarks made by the ' subject ' specified at the bottom. Some of the reproductions exhibit the curious pheno- menon of inversion. These drawings must speak for themselves. The principal facts to be borne in mind regarding them are that they have been executed through the instrumentality, as agents, of persons of unquestioned probity, and that the responsibility for them is spread over a considerable group of such persons ; while the conditions to be observed were so simple — for they amounted really to nothing more than taking ^ The fuU record of the experiments wiU be found in the Proceedings of the S.P.R., vol. i., p. 264, &c., and vol. ii., p. 24, &c. There is one point of novelty which is thus described by Mr. Guthrie : " We tried also the perception of motion, and found that the movements of objects exhibited could be discerned. The idea was suggested by an experiment tried with a card, which in order that all present should see, I moved about, and was informed by the percipient that it was a card, but she could not tell which one because it seemed to be moving about. On a subsequent occasion, in order to test this perception of motion, I bought a toy monkey, which worked up and down on a stick by means of a string drawing the arms and legs together. The answei- was : ' I see red and yellow, and it is darker at one end than the other. It is like a flag moving about — it is moving. . . , Now it is opening and shutting like a pair of soissors.' " 30 THE EXPERIMENT A L BA SIS : [Chap. II care that the original should not be seen by the ' subject ' — that it is extremely difficult to suppose them to have been eluded." I give a few specimens — not unduly favourable ones, but illustrating the " spreading of responsibility " to which Mr. Guthrie refers. The agents concerned were Mr. Guthrie ; Mr. Steel, the President of the Liverpool Literary and Philosophical Society ; Mr. Birchall, mentioned above ; Mr. Hughes, B.A., of St. John's College, Cambridge ; and myself. The names of the percipients were Miss Relph and Miss Edwards. The conditions which I shall describe were those of the experiments in which I myself took part ; and I have Mr. Guthrie's authority for stating that they were uniformly observed in the other cases. The originals were for the most part drawn in another room from that in which the percipient was placed. The few executed in the same room were drav\'n while the percipient was blindfolded, at a distance from her, and in such a way that the process would have been wholly invisible to her or anyone else, even had an attempt been made to observe it. During the process of transference, the agent looked steadily and in perfect silence at the original drawing, which was placed upon an intervening wooden stand ; the percipient sitting opposite to him, and behind the stand, blindfolded and quite still. The agent ceased looking at the drawing, and the blind- folding was removed, only when the percipient professed herself ready to make the reproduction, which happened usually in times varying from half-a-minute to two or three minutes. Her position rendered it absolutely impossible that she should obtain a glimpse of the original. Apart from the blindfolding, she could not have done so without rising from her seat and advancing her head several feet ; and as she was very nearly in the same line of sight as the drawing, and so very nearly in the centre of the agent's field of vision, the slightest approach to such a movement must have been instantly detected. The reproductions were made in perfect silence, the agent forbearing to follow the actual process of the drawing with his eyes, though he was, of course, able to keep the percipient under the closest observation. In the case of all the diagrams, except those numbered 7 and 8, the agent and the percipient were the only two persons in the room during the experiment. In the case of numbers 7 and 8, the agent and Miss Relph were sitting quite apart in a corner of the room, while Mr. Guthrie and Miss Edwards were talking in another part of it. Numbers 1-6 are specially interesting as being the complete and consecutive series of a single sitting. Chap. II; THOUGHT-TRANSFERENCE 31 No. 1. O-RiGiNAL Drawing. No. 1. Rhproduction.
