II. Experiments of the later stage when the percipient was left alone unwatched with the original drawings in her possession. Theory: Conscious or unconscious inspection of the original drawings. Difficulty which the theory faces: The results did not improve or undergo alterations due to a new cause during the unguarded period.

III. Experiments when agent and percipient were either thirty feet apart in different rooms, with a closed door between, under which circumstances it is incredible that involuntary whispering could have been heard, or thirty miles apart, in which case it is unquestionably impossible that involuntary whispering could have carried. Theory: Chance coincidence. This is the only theory left for such experiments, unless conspiracy is charged, and that at different times would have to include not only Mr. and Mrs. Sinclair, but Mr. Irwin, Mrs. Irwin, the Sinclairs’ secretary and Professor McDougall. Refutation of the theory: The experiments in this class were of such number and had such success both in number and quality as to challenge the production of any such success by guessing though hundreds of series each of an equal number of experiments should be gone through with.

It is credible that the large percentage of Successes and Partial Successes in the first 14 experiments and 24 among the latest ones should have been obtained by one method, that (aside from these) during the earlier months another and quite different method should have been employed, and that (still aside from these) later a third and quite different method should have been resorted to, and yet the whole mass of results be homogeneous? It would certainly be expected that the inauguration of any new method would in some way be reflected in the nature of the results. But the lot produced with intervening distances too great to admit of the involuntary whispering theory melts imperceptibly into the lot produced with the agent and percipient together so that the involuntary whispering process is conceivable, and this in turn melts imperceptibly into the lot where all precautions are discarded, and this again into long-distance experiments and out, without it being possible to detect any changes in the character of the results at the points of junction. Throughout there is homogeneity, some successes being correct literally, some incompletely and partially, some results only suggestive and some entire failures. Throughout we find some corresponding in both shape and meaning, some in idea but not shape, and some in shape only and misinterpreted by the percipient; in fact, all the peculiarities of Mrs. Sinclair’s work are to be found in about equal proportions in all stages. There is perceptible a gradual though irregular tendency to decline in the ratio of success achieved, but in such a manner that the decline cannot be chronologically connected with any of the changes of method.

The “peeking” theory cannot be applied to the experiments of Class I. The “involuntary whispering” theory cannot be applied to the experiments of Class II. Neither the “peeking” nor the “involuntary whispering” theory can be applied to experiments of Class III.

Only the theory of chance coincidence can be applied as a single explanation of the experiments of all three classes. Let this be done and there is simply massed a greater amount of material for the demolition of the chance coincidence theory by anyone who will undertake a large series of precisely parallel experiments in Guessing.

For myself, I am willing to say, perhaps for the fourth time, that I am willing to rest the whole case on those experiments to which no one, presumably, will have the hardihood to apply either the theory of “involuntary whispering” or that of “peeking,” that is to say, those experiments in which agent and percipient were either in separate rooms or many miles apart.

An Interpretation of Mrs. Sinclair’s Directions

Mrs. Sinclair, on pages [116]–128 of Mental Radio, outlines on the basis of her own experience the method which she thinks best calculated to develop an ability to attain at will a mental state which will enable some of her readers to receive and record telepathic impressions to an evidential degree. I propose, at the same time recommending that prospective experimenters shall obtain the book and read the full directions, to attempt a condensation of them. To some extent I shall interpret them; that is, state them in other terms, which it is hoped will not be the less lucid. As a matter of psychological fact, you cannot “make your mind a blank,” though you can more or less acquire the art of doing at will what you sometimes involuntarily do—you can practice narrowing the field of consciousness, so that instead of being aware of many things external and of various bodily sensations, your attention is fixed almost exclusively for a time on one mental object. Some persons at times become so absorbed in a train of thought that with eyes open and with conversation around them they are hardly conscious of anything seen or heard. But it is best to assist the attainment of such a state as Mrs. Sinclair does, by closing the eyes, and it is best that silence should prevail. When one remembers how in revery he has become oblivious to all around him, or how when witnessing an entrancing passage in a play everything in the theatre except the actors and their immediate environment has faded out of consciousness, he will have no difficulty in understanding what Mrs. Sinclair really means by saying that “it is possible to be unconscious and conscious at the same time,” although taken literally that is not a correct statement.

But, according to her, in order to be in the state best fitted for telepathic reception, it is not enough to narrow the field of consciousness until, approximately, only one train of thought on a mentally conceived subject occupies it. There must be cultivated also, in as high a degree as possible, an ability to shut out memories and imaginations, and to wait for and to receive impressions, particularly those of mental imagery, which seem to come of themselves, and to expend the mental energy upon watching, selecting from and determining these.

We are told that it is important to relax—“to ‘let go’ of every tense muscle, every tense spot, in the body,” and that auto-suggestion, mentally telling oneself to relax, will help. Along with this there should be a letting-go, or progressive quietening, of consciousness.
