The reader will have observed that up to the present moment I have not emphasized in any way the question of the identity of the "intelligences" that have manifested themselves. The reason for this lies in the fact that I was still seeking evidence concerning the processes of mediumship. However, being convinced (by reason of my own experiments, supported by those of Lombroso, Morselli, and Bottazzi) that the facts of mediumship exist, it is my purpose to take up definitely the question of identity, which is the final and most elusive part of the problem--it may turn out to be the insoluble part of the problem. If you ask why it should be insoluble, I reply, because it concerns the mystery of death, and it may be that it is not well for us to penetrate the ultimate shadow. Among all the men of the highest rank who admit the reality of apparitions and voices, there are but few as yet who are willing to assert that the dead manifest themselves. By this I mean that though some of them, like Crookes, for example, believe in "the intervention of discarnate intelligences," they are not ready to grant that these intelligences are their grandfathers returning to the scene of their earthly labors. I said something like this to Miller and Fowler, when we met at the club one afternoon not long after the final meeting of Cameron's Amateur Psychical Society, and I added: "I must confess that most of the spirits I have met seem to me merely parasitic or secondary personalities (to use Maxwell's term), drawn from the psychic or from myself. Nearly every one of the mediums I have studied has had at least one guide, whose voice and habit of thought were perilously similar to her own. This, in some cases, has been laughable, as when 'Rolling Thunder,' a Sioux chief (Indians are all chiefs in the spirit world), appears and says: 'Goot efening, friends; id iss a nice night alretty.' And yet I have seen a whole roomful of people receive communications from a spirit of this kind with solemn awe. I burn with shame for the sitters and psychic when this kind of thing is going on." "You visit the wrong mediums," said Fowler. "Such psychics are on a low plane. I never go to those who associate with Indians." "But mediums are all alike in this respect. I don't suppose Mrs. Smiley realizes that 'Maudie' would be called by a doubter a falsetto disguise of her own voice, and 'Wilbur' a shrewd and humorous personification of her subconscious self; or, if she does, she probably ascribes it to the process of materialization which 'takes from' the medium. Never but once have I had the sensation of being in the presence of a real spirit personality, and that happened to me only a few days ago." "It must have been an extraordinary experience to have made so deep an impression upon you," said Fowler.
