research, reagents like litmus paper or the galvanometer, for revealing what would otherwise be hidden. These are so many ways of putting the Subliminal on tap. Of course without the simultaneous work on hypnotism and hysteria independently begun by others, he could not have pushed his own work so far. But he is so far the only generalizer of the problem and the only user of all the methods; and even though his theory of the extent of the Subliminal should have to be subverted in the end, its formulation will, I am sure, figure always as a rather momentous event in the history of our science.
Any psychologist who should wish to read Myers out of the profession—and there are probably still some who would be glad to do so to-day—is committed to a definite alternative. Either he must say that we knew all about the subliminal region before Myers took it up, or he must say that it is certain that states of super-normal cognition form no part of its content. The first contention would be too absurd. The second one remains more plausible. There are many first-hand investigators into the Subliminal who, not having themselves met with anything super-normal, would probably not hesitate to call all the reports of it erroneous, and who would limit the Subliminal to dissolutive phenomena of consciousness exclusively, to lapsed memories, subconscious sensations, impulses and phobias, and the like. Messrs. Janet and Binet, for aught I know, may hold some such position as this. Against it Myers's thesis would stand sharply out. Of the Subliminal, he would say, we can give no ultra-simple account: there are discrete regions in it, levels separated by critical points of transition, and no one formula holds true of them all. And any conscientious psychologist ought, it seems to me, to see that, since these multiple modifications of personality are only beginning to be reported and observed with care, it is obvious that a dogmatically negative treatment of them must be premature, and that the problem of Myers still awaits us as the problem of far the deepest moment for our actual psychology, whether his own tentative solutions of certain parts of it be correct or not.
Meanwhile, descending to detail, one cannot help admiring the great originality with which Myers wove such an extraordinarily detached and discontinuous series of phenomena together. Unconscious cerebration, dreams, hypnotism, hysteria, inspirations of genius, the willing-game, planchette, crystal-gazing, hallucinatory voices, apparitions of the dying, medium-trances, demoniacal possession, clairvoyance, thought-transference—even ghosts and other facts more doubtful—these things form a chaos at first sight most discouraging. No wonder that scientists can think of no other principle of unity among them than their common appeal to men's perverse propensity to superstition.
