part in the Fairy legend. Thence Mr. Kirk glides into that singular theory of savage metaphysics which somewhat resembles the Platonic doctrine of Ideas. All things, in Red Indian belief, have somewhere their ideal counterpart or “Father.” Thus a donkey, when first seen, was regarded as “the Father” or archetype “of Rabbits.” Now the second-sighted behold the “Double-man,” “Doppel-ganger,” “Astral Body,” “Wraith,” or what you will, of a living person, and that is merely his counterpart in the abstruse world. The industry of the Psychical Society has collected much material—evidence, whatever its value, for the existence of the Double-man. We may call it a hallucination, which does not greatly increase our knowledge. From personal experience, and the experience of friends, I am constrained to believe that we may think we see a person who is not really present to the view—who may be in the next room, or downstairs, or a hundred miles off. This experience has occurred to the sane, the unimaginative, the healthy, the free from superstition, and in circumstances by no means mystic—for example, when the person supposed to be seen was not dying, nor distressed, nor in any but the most normal condition. Indeed, the cases when there was nothing abnormal in the state of the person seen are far more numerous, in my personal knowledge, than those in which the person seen was dying, or dead, or excited. The reverse appears to be the rule in the experience of the Psychical Society. “The actual proportion of coincidental to non-coincidental cases, after all deduction for possible sources of error, was in fact such that the probability against the supposition of chance coincidence became enormous, on the assumption of ordinary accuracy on the part of informants” (Professor Sidgwick, _Proc. S.P.R._, vol. viii. p. 607). Some 17,000 answers were collected. We must apparently accept these facts as not very abnormal nor very unusual, and doubtless as capable of some subjective explanation. But when such things occurred among imaginative and uneducated Highlanders, they became foundations and proofs of the doctrine of second sight—proofs, too, of the primitive metaphysical doctrine of counterparts and _correspondances_. “They avouch that every Element and different state of Being have Animals resembling these of another Element.” By persons not knowing this, “the Roman invention of guardian Angels particularly assigned” has been promulgated. The guardian Angel of the Roman superstition is merely the Double or Co-walker—the type (in the viewless world) of the man in the apparent world. Thus are wraiths and ghosts explained by our Presbyterian psychologist and his Highland flock. All things universally have their types, their reflex: a man’s type, or reflex, or “co-walker” may be seen at a distance from or near him during his life—nay, may be seen after his death. The gifted man of second sight can tell the substantial figure from the airy counterpart.
