Putting these exceptional instances aside, we find that the writings generally take the form of a dialogue, Mr. Moses proposing a question in his ordinary thick, black handwriting. An answer is then generally, though not always, given; written also by Mr. Moses, and with the same pen, but in some one of various scripts which differ more or less widely from his own. Mr. Moses' own description of the process, as given in the preface to Spirit Teachings, may be studied with advantage.
A prolonged study of the MS. books has revealed nothing inconsistent with this description. I have myself, of course, searched them carefully for any sign of confusion or alteration, but without finding any; and I have shown parts of them to various friends, who have seen no points of suspicion. It seems plain, moreover, that the various entries were made at or about the dates to which they are ascribed. They contain constant references to the séances which went on concurrently, and whose dates are independently known; and in the later books, records of some of these séances are interspersed in their due places amongst other matter. The MSS. contain also a number of allusions to other contemporaneous facts, many of which are independently known to myself.
I think, moreover, that no one who had studied these entries throughout would doubt the originally private and intimate character of many of them. The tone of the spirits towards Mr. Moses himself is habitually courteous and respectful. But occasionally they have some criticism which pierces to the quick, and which goes far to explain to me Mr. Moses' unwillingness to have the books fully inspected during his lifetime. He did, no doubt, contemplate their being at least read by friends after his death; and there are indications that there may have been a still more private book, now doubtless destroyed, to which messages of an intimate character were sometimes consigned.
Indeed, the questions at issue, as to these messages, refer not so much to their genuineness as to their authenticity, in the proper sense of those words. That they were written down in good faith by Mr. Moses as proceeding from the personages whose names are signed to them, there can be little doubt. But as to whether they did really proceed from those personages or no there may in many cases be very great doubt;—a doubt which I, at least, shall be quite unable to remove. By the very conditions of the communication they cannot show commanding intellect, or teach entirely new truths, since their manifestations are ex hypothesi limited by the capacity—not by the previous knowledge, but by the previous capacity—of the medium. And if they give facts not consciously known to the medium—facts however elaborate—it may, of course, be suggested that these facts have been subliminally acquired by the medium through some unconscious passage of the eye over a printed page, or else that they are clairvoyantly learnt, without the agency of any but the medium's own mind, though acting in a supernormal fashion.
The case of Hélène Smith has shown us how far-reaching may be the faculties of hyperæsthesia and hypermnesia in the subliminal self; but in view of the then general ignorance of the scientific world on this subject, it is not surprising that both Mr. Moses and his friends absolutely rejected this explanation of his phenomena, and that the evidence appeared to them more conclusive than it possibly can to us. Whether or not the alleged spirits were concerned,—as may sometimes, of course, have been the case,—we can hardly avoid thinking that the subliminal self of the medium played at least a considerable part in the communications.
In two cases the announcement of a death was made to Mr. Moses, when the news was apparently not known to him by any normal means. One of these is the case of President Garfield (Proceedings S.P.R., vol. xi. p. 100). The other (see my article in Proceedings S.P.R., vol. xi. pp. 96 et seq.) is in some ways the most remarkable of all, from the series of chances which have been needful in order to establish its veracity. Specially noticeable in this case is the resemblance of the handwriting of the script to that of the alleged control, a lady whose writing was almost certainly unknown to Mr. Moses. Both to the lady's son and to myself the resemblance appeared incontestable, and our opinion was confirmed by Dr. Hodgson, who was an expert in such matters.
And now we must briefly go through the points which make such messages as were received by Mr. Moses primâ facie evidential, which indicate, that is to say, that they actually do come in some way from their alleged source. A brief recapitulation of the main stages of evidential quality in messages given by automatic writing or by trance-utterances is all that will be needed here.
(1) Evidentially lowest comes the class of messages which is by far the most common; messages, namely, in which, although some special identity may be claimed, all the facts given have been consciously known to the automatist. Here we may well suppose that his own personality alone is concerned, and that the messages have a subliminal, but not an external source.
(2) Next above these come messages containing facts likely to be known to the alleged spirit, and not consciously known to the automatist; but which facts may nevertheless have some time been noted by the automatist, even unwittingly, and may have thus obtained lodgment in his subliminal memory.
(3) Next come facts which can be proved,—with such varying degrees of certainty as such negative proof allows,—never to have been in any way known to the automatist; but which nevertheless are easily to be found in books; so that they may have been learnt clairvoyantly by the automatist himself, or learnt and communicated to him by some mind other than that of the alleged spirit.
