I said a while ago that his intellect was not by nature philosophic in the narrower sense of being that of a logician. In the broader sense of being a man of wide scientific imagination, Myers was most eminently a philosopher. He has shown this by his unusually daring grasp of the principle of evolution, and by the wonderful way in which he has worked out suggestions of mental evolution by means of biological analogies. These analogies are, if anything, too profuse and dazzling in his pages; but his conception of mental evolution is more radical than anything yet considered by psychologists as possible. It is absolutely original; and, being so radical, it becomes one of those hypotheses which, once propounded, can never be forgotten, but sooner or later have to be worked out and submitted in every way to criticism and verification. The corner-stone of his conception is the fact that consciousness has no essential unity. It aggregates and dissipates, and what we call normal consciousness,--the "Human Mind" of classic psychology,--is not even typical, but only one case out of thousands. Slight organic alterations, intoxications, and auto-intoxications, give supraliminal forms completely different, and the subliminal region seems to have laws in many respects peculiar. Myers thereupon makes the suggestion that the whole system of consciousness studied by the classic psychology is only an extract from a larger total, being a part told-off, as it were, to do service in the adjustments of our physical organism to the world of nature. This extract, aggregated and personified for this particular purpose, has, like all evolving things, a variety of peculiarities. Having evolved, it may also dissolve, and in dreams, hysteria, and divers forms of degeneration it seems to do so. This is a retrograde process of separation in a consciousness of which the unity was once effected. But again the consciousness may follow the opposite course and integrate still farther, or evolve by growing into yet untried directions. In veridical automatisms it actually seems to do so. It drops some of its usual modes of increase, its ordinary use of the senses, for example, and lays hold of bits of information which, in ways that we cannot even follow conjecturally, leak into it by way of the Subliminal. The ulterior source of a certain part of this information (limited and perverted as it always is by the organism's idiosyncrasies in the way of transmission and expression) Myers thought he could reasonably trace to departed human intelligence, or its existing equivalent. I pretend to no opinion on this point, for I have as yet studied the evidence with so little critical care that Myers was always surprised at my negligence. I can therefore speak with detachment from this question and, as a mere empirical psychologist, of Myers' general evolutionary conception. As such a psychologist I feel sure that the latter is a hypothesis of
