my being able to prevent it, without my even knowing it? * * * What is myself, anyway—body or mind, or both, or one and the same thing, or—what? I must find out! Is my mind a hodge-podge of its own thoughts and the silent, ever-changing thoughts of all other creatures, just as my body is a hodge-podge of the elements of the plants and animals and light-rays it is fed on and made of? Here were a lot of questions which had become terribly important, and I couldn’t answer them, I couldn’t really answer any of them. But I had a clue—a new clue which might lead—anywhere—to heaven or to hell. * * * Some of the best scientific minds of the world have experimented with telepathy and believe that it is a proven fact. I have read much of this evidence, and I have watched a “medium” demonstrate telepathy. But perhaps he was deceiving himself—perhaps he used some trick without realizing it, such as listening to the breathing of the sender of the thoughts he received. I do not see how this could be, but it is possible, so I am told by experienced investigators of psychic phenomena. However, there is this mass of evidence, in books, written by men of the highest scientific training who have made experiments in telepathy and who are convinced that it is a fact. * * * But despite all this evidence, I seem to be uncertain. And this is too serious a matter to leave to uncertainty. So I set to work to make my own experiments. I have experimented already with a “medium,” but I have been warned about the mediumistic temperament. These psychically sensitive persons are, thanks to the very quality of mind which causes them to be sensitive, overly prone to unconscious thinking which is supposed to take a form of conscious instability. So I must find a hard-boiled materialistic-thinking person to experiment with—one who is prone to object thinking, who can maintain a wide-awake consciousness with which to watch his own thoughts to prevent any self-deception, while I, by a trustworthy mechanical device, _i.e._, a writing pad and pencil, protect my mind from deceiving itself. I find such a hard-boiled object mind in the person of my brother-in-law, who is a most capable, practical business man, and whose philosophy of life does not include any “mysticism,” or unconscious knowledge. Being ill, however, and with no better way to pass the time, he consents to act as sender of telepathic messages to me. He is domiciled thirty miles away from me, and so we cannot look over each other’s shoulders at drawings, nor listen to each other’s breathing.
