And in saying this, I am well aware that, even if my belief is in agreement with that entertained by many eminent men of science—such as Sir Oliver Lodge, Sir William Crookes, Camille Flammarion, Charles Richet, Theodore Flournoy, Henri Morselli, Professor W. F. Barrett and the late William James—it is contrary to the opinion held by the great majority of scientists at the present day. Their view, to put it briefly, is that there is no such thing as telepathy; that chance coincidence, deliberate or unconscious falsification, and errors of memory are sufficient to explain most instances of alleged telepathic communication; and that the remainder are reducible to the operation of more or less familiar principles in the psychology of the subconscious—notably the law of hyperæsthesia, or unusual extension of the senses of sight, hearing, smell, etc.
I am perfectly willing to admit that much which passes as telepathy may be thus reducible. For example, I am seated writing at the desk in my study. Unexpectedly there flashes into my mind an idea concerning a person of whom I have not thought for weeks or months. The next instant the doorbell rings, and presently the maid informs me that the very person of whom I have that moment been thinking has entered the house.
This is a not infrequent experience, as most of my readers will concede. So frequent is it that it is absurd to attempt to account for it on the hypothesis of chance coincidence. But neither would it be always safe to raise the theory of telepathy. For it might well happen that while I was seated intent on my work, with the study windows closed, my ear nevertheless caught the sound of footsteps coming down the street, or on my porch; that I subconsciously recognized in them my friend’s walk, and that I consequently, though without knowing why, thought of him at that precise moment. This is assuredly a possible explanation—though I am far from conceding that in all such cases it is the only explanation properly applicable.
So, likewise, one must be constantly on guard against over-readily accepting as evidences of telepathic action the feats of “mind reading” often undertaken by way of parlor amusement. Stage “mind reading” by professional entertainers may be safely left out of the reckoning, as undoubtedly based on methods of conscious trickery and deceit. But in a private gathering, where there can be no question of confederates and deliberate signaling, surprising results are sometimes obtained in the finding of hidden objects, etc. On the surface this would seem explicable only on a telepathic basis, yet in reality it is commonly brought about by “muscle reading” rather than by true “mind reading.”
Experiment has shown that the effort to concentrate thought on a given matter—a name or an object—tends to produce some form of muscular activity, either subconscious whispering of the name thought of, or subconscious movement in the direction of the object. If, as is the rule, the spectators are supposed to keep their minds fixed intently on the name or object they have selected for the “test,” some of them are apt to give these involuntary muscular hints, which the performer will accept and act upon, it may be without being clearly conscious of the source of his information.
Still it must be added that experiments in the “willing game” have been carried out under conditions and with results indicating that occasionally, at all events, successes are achieved without any such subconscious guidance. Not so very long ago some interesting and most striking experiments of this sort were described to me by Professor J. H. Hyslop.
“The subject of my experiments,” said he, “was a young woman of good family, who was credited with having exceptional ability in divining the thoughts and wishes of others. It was arranged that I should investigate her powers, and accordingly for a period of some weeks I had frequent sittings with her, in the presence of a few interested and trustworthy friends.
“The plan followed in every experiment was this: The young woman having left the room, I mentally selected some more or less complicated action for her to perform upon her return. I then wrote down on a slip of paper what I wished her to do, showed it to the others, and concealed it in a book, which did not leave my hand until after the completion of the experiment. From first to last not a word was spoken by any one, so as to guard against any possible hyperæsthesia of hearing on her part.
“The young woman was then called back, and almost invariably proceeded to execute the commands mentally given her. She did this so promptly that I cannot conceive how she could possibly have got any unconscious hints from those present, and conscious signaling was out of the question.
“For instance, I once wrote on my paper an order for her to pick out of a vase a bunch of keys I had hidden there, cross the room with the keys, and place them on the mantel-piece. She entered, stood for but a moment with her eyes closed, and then, swiftly passing to the vase, which was on the floor, picked up the keys, turned, and deposited them on the mantel-piece as I had mentally suggested. It was all done so quickly and spontaneously that to my mind it afforded strong evidential proof of true thought transference.
