It would be rash, however, to represent as crucial any apparent transferences 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 which third parties have arranged conditions and guarded against signs. The conditions of a crucial result, for one’s own mind, are either (1) 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 impossibility. 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.1 As regards the experiments of which I am about to present a sketch, it is not necessary to my argument that any individual’s honesty shall be completely assumed, in the sense of being used as a certain basis for conclusions. The proof must depend on the number of persons, reputed honest and intelligent, to whom dishonesty or imbecility 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 experiments, would have carried away a far more vivid impression of their genuineness than any printed record can convey. But it must be distinctly understood that we discriminate our cases; and that even where the results are to our own minds crucial—in that they can only be impugned 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, therefore, 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 months, 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 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 years 1881 and 1882, a large number of experiments 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
