_I can hardly suppose he means to apply this statement to more than the small residue of phenomena which he finds inexplicable on any other hypothesis. Assuming this restricted view to be meant, the question arises, Is the evidence on which it is based sufficiently_ abundant, trustworthy, _and_ conclusive, _to warrant such a far-reaching statement? Here we must turn from the author to ascertain what has been the conclusion arrived at by those who have given long years to a searching experimental investigation of these phenomena, and who have approached the subject in a scientific and judicial spirit. The most noteworthy instance is the testimony of that shrewd and able investigator, the late Dr Hodgson. His patient and laborious inquiry into the trance phenomena of Mrs Piper ultimately led him to the conclusion arrived at by Mr Willson. Dr Hodgson's well-known exposure of Madame Blavatsky and other fraudulent mediums and his sane and cautious judgment render his opinion of great weight. Then, again, we find that this also was the conclusion to which Frederic Myers was gradually driven. And long prior to this it was the conclusion arrived at by that acute thinker, the late Professor de Morgan, and it is the conclusion strongly held by the great naturalist, Dr A. R. Wallace, and held also by several other eminent investigators I might name._ _So momentous a conclusion, if capable of such complete verification as to be universally accepted by science, would obviously throw all other discoveries into the background. I say if capable of being verified by scientific methods, but, although the weight of opinion will, in my opinion, ultimately lead to a very wide acceptance of this conclusion, yet it seems to me highly probable that the experimental discovery of the survival of human personality after death will always elude conclusive scientific demonstration. This particular field of psychical investigation belongs to an order other than that with which science deals; and, this being so, it can never be adequately investigated with the limited faculties we now possess._
