(IV.) Passing on to phantasms which cluster about the moment of death, we find our three main classes of cases still meeting us. Our readers are familiar with the visual cases, where there is an actual apparition of the dying man, seen by one or more persons; and also with the emotional and motor cases, where the impression, although powerful, is not definitely sensory in character. And various cases also have been published where the message has consisted of definite words, not always externalised as an auditory hallucination, but sometimes automatically uttered or automatically written by the percipient himself, as in the case communicated by Dr. Liébeault (see Appendix VIII. C), where a girl writes the message announcing her friend's death at the time when that friend is, in fact, dying in a distant city.

(V.) And now I maintain that in these post-mortem cases also we find the same general classes persisting, and in somewhat the same proportion. Most conspicuous are the actual apparitions, with which, indeed, the following pages will mainly deal. It is very rare to find an apparition which seems to impart any verbal message; but a case of this kind has been given in Appendix IV. F. As a rule, however, the apparition is of the apparently automatic, purposeless character, already so fully described. We have also the emotional and motor class of post-mortem cases;[131] and these may, perhaps, be more numerous in proportion than our collection would indicate; for it is obvious that impressions which are so much less definite than a visual hallucination (although they may be even more impressive to the percipient himself) can rarely be used as evidence of communication with the departed.

But now I wish to point out that, besides these two classes of post-mortem manifestations, we have our third class also still persisting; we have definite verbal messages which at least purport, and sometimes, I think, with strong probability, to come from the departed.

I have, indeed, for the reader's convenience, postponed these motor cases to a subsequent chapter, so that the evidence here and now presented for survival will be very incomplete. Yet, at any rate, we are gradually getting before us a fairly definite task. We have in this chapter to record and analyse such sensory experiences of living men as seem referable to the action of some human individuality persisting after death. We have also obtained some preliminary notion as to the kind of phenomena for which we can hope, especially as to what their probable limitations must be, considering how great a gulf between psychical states any communication must overpass.

Let us now press the actual evidential question somewhat closer. Let us consider, for it is by no means evident at first sight, what conditions a visual or auditory phantasm is bound to fulfil before it can be regarded as indicating primâ facie the influence of a discarnate mind. The discussion may be best introduced by quoting the words in which Edmund Gurney opened it in 1888.[132] The main evidential lines as there laid down retain their validity, although the years which have since passed have greatly augmented the testimony, and in so doing have illustrated yet other tests of true post-mortem communication,—to which we shall presently come.

"It is evident that in alleged cases of apparitions of the dead, the point which we have held to distinguish certain apparitions of living persons from purely subjective hallucinations is necessarily lacking. That point is coincidence between the apparition and some critical or exceptional condition of the person who seems to appear; but with regard to the dead, we have no independent knowledge of their condition, and therefore never have the opportunity of observing any such coincidences.

"There remain three, and I think only three, conditions which might establish a presumption that an apparition or other immediate manifestation of a dead person is something more than a mere subjective hallucination of the percipient's senses. Either (1) more persons than one might be independently affected by the phenomenon; or (2) the phantasm might convey information, afterwards discovered to be true, of something which the percipient had never known; or (3) the appearance might be that of a person whom the percipient himself had never seen, and of whose aspect he was ignorant, and yet his description of it might be sufficiently definite for identification. But though one or more of these conditions would have to be fully satisfied before we could be convinced that any particular apparition of the dead had some cause external to the percipient's own mind, there is one more general characteristic of the class which is sufficiently suggestive of such a cause to be worth considering. I mean the disproportionate number of cases which occur shortly after the death of the person represented. Such a time-relation, if frequently enough encountered, might enable us to argue for the objective origin of the phenomenon in a manner analogous to that which leads us to conclude that many phantasms of the living have an objective (a telepathic) origin. For, according to the doctrines of probabilities, a hallucination representing a known person would not by chance present a definite time-relation to a special cognate event—viz., the death of that person—in more than a certain percentage of the whole number of similar hallucinations that occur; and if that percentage is decidedly exceeded, there is reason to surmise that some other cause than chance—in other words, some objective origin for the phantasm—is present."

But on the other hand, a phantasm representing a person whose death is recent is specially likely to arouse interest and, in cases where the death is previously known to the percipient, his emotional state may be considered a sufficient cause of the hallucination.

"If, then," Gurney continues, "we are to draw any probable conclusion as to the objective nature of post-mortem appearances and communications (or of some of them) from the fact of their special frequency soon after death, we must confine ourselves to cases where the fact of death has been unknown to the percipient at the time of his experience. Now, in these days of letters and telegrams, people for the most part hear of the deaths of friends and relatives within a very few days, sometimes within a very few hours, after the death occurs; so that appearances of the sort required would, as a rule, have to follow very closely indeed on the death. Have we evidence of any considerable number of such cases?

"Readers of Phantasms of the Living will know that we have. In a number of cases which were treated in that book as examples of telepathic transference from a dying person, the person was actually dead at the time that the percipient's experience occurred; and the inclusion of such cases under the title of Phantasms of the Living naturally occasioned a certain amount of adverse criticism. Their inclusion, it will be remembered, required an assumption which cannot by any means be regarded as certain. We had to suppose that the telepathic transfer took place just before, or exactly at, the moment of death; but that the impression remained latent in the percipient's mind, and only after an interval emerged into his consciousness, whether as waking vision or as dream or in some other form. Now, as a provisional hypothesis, I think that this assumption was justified. For in the first place, the moment of death is, in time, the central point of a cluster of abnormal experiences occurring to percipients at a distance, of which some precede, while others follow, the death; it is natural, therefore, to surmise that the same explanation will cover the whole group, and that the motive force in each of its divisions lies in a state of the 'agent' prior to bodily death. In the second place, some of the facts of experimental thought-transference countenance the view that 'transferred impressions' may be latent for a time before the recipient becomes aware of them; and recent discoveries with respect to the whole subject of automatism and 'secondary intelligence' make it seem far less improbable than it would otherwise have seemed that telepathy may take effect first on the 'unconscious' part of the mind.[133] And in the third place, the period of supposed latency has in a good many instances been a period when the person affected was in activity, and when his mind and senses were being solicited by other things; and in such cases it is specially easy to suppose that the telepathic impression did not get the right conditions for rising into consciousness until a season of silence and recueillement arrived.[134] But though the theory of latency has thus a good deal to be said for it, my colleagues and I are most anxious not to be supposed to be putting forward as a dogma what must be regarded at present merely as a working hypothesis. Psychical research is of all subjects the one where it is most important to avoid this error, and to keep the mind open for new interpretations of the facts. And in the present instance there are certain definite objections which may fairly be made to the hypothesis that a telepathic impression derived from a dying person may emerge after hours of latency. The experimental cases to which I have referred as analogous are few and uncertain, and, moreover, in them the period of latency has been measured by seconds or minutes, not by hours. And though, as I have said, some of the instances of apparent delay among the death-cases might be accounted for by the fact that the percipient's mind or senses needed to be withdrawn from other occupations before the manifestation could take place, there are other instances where this is not so, and where no ground at all appears for connecting the delay with the percipient's condition. On the whole, then, the alternative hypothesis—that the condition of the phenomenon on the 'agent's' side (be it psychical or be it physical) is one which only comes into existence at a distinct interval after death, and that the percipient really is impressed at the moment, and not before the moment, when he is conscious of the impression—is one which must be steadily kept in view.
