There might be thus a kind of eager pressing of the departed against the doors which had been shut and not quite locked behind them, taking the form of more or less obscure suggestion to which the medium would be sensitive and so recreate in ways at which we can only guess some hint of the voice or presence of the discarnate. The suggestion would come from the other side. The form in which it is given to our world would be the contribution of the medium. As far as there is any possible explanation of the facts of trance mediumship as a revelation from the dead it is somewhere here. Telepathy between the living is fairly well enough established to make this a not impossible hypothesis, and even materialization might be accounted for in the same way. Sir Oliver Lodge is inclined to discover in the luminiferous ether an environment in which discarnate personality could function. But this is pure supposition, though others have adopted it. Walker, for example, in his extremely suggestive work on Monism and Christian Theism. But he suggests the ether only as a help to the imagination in meeting the difficulties of an immortal existence--the old Heaven and Hell having been made astronomically and geologically impossible. But if Einstein should upset the hypothesis of the ether all this would go the way of the Heaven and Hell of Dante. We cannot eliminate, however, in a supposition so vague as this the contributive elements supplied by the friends themselves to whom the communication is supposed to be addressed and by whom it is certainly interpreted, for if the trance medium is open to suggestion from the discarnate side, the medium must be equally open to suggestion from the living, a suggestion likely to be very much stronger, more distinct, more compelling. The real crux of the whole problem is the disentanglement of these possible lines of suggestion and the assignment of them to their true sources. We may, the writer believes, eliminate as far as their evidential value is concerned, all physical phenomena. In doing this we need not necessarily deny the reality of some of the physical phenomena but the larger part of the residue which might possibly be left after the elimination of fraud on the part of the medium and unintentional misrepresentation on the part of the witnesses is so utterly meaningless as to have no value at all. The only physical phenomena which can have any direct bearing on spirit communication are the tappings and table tippings which can by a deal of ingenuity be made to spell out a message or answer questions yes or no. The same question as to the source of the suggestion enters here. Even if we admit the taps to spell out a message, we have still to decide from whom the message comes and the messages alleged to be contributed through the voice are so much more full and intelligible as to leave the whole question standing or falling with the credibility of voice trance mediumship. _Controls_
