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. Yet Myers has actually made a system of them, stringing them continuously upon a perfectly legitimate objective hypothesis, verified in some cases and extended to others by analogy. Taking the name "automatism" from the phenomenon of automatic writing--I am not sure that he may not himself have been the first so to baptize this latter phenomenon--he made one great simplification at a stroke by treating hallucinations and active impulses under a common head, as _sensory_ and _motor automatisms_. Automatism he then conceived broadly as a message of any kind from the Subliminal to the Supraliminal. And he went a step farther in his hypothetic interpretation, when he insisted on "symbolism" as one of the ways in which one stratum of our personality will often interpret the influences of another. Obsessive thoughts and delusions, as well as voices, visions, and impulses, thus fall subject to one mode of treatment. To explain them, we must explore the Subliminal; to cure them we must practically influence it. Myers' work on automatism led to his brilliant conception, in 1891, of hysteria. He defined it, with good reasons given, as "a disease of the hypnotic stratum." Hardly had he done so when the wonderfully ingenious observations of Binet, and especially of Janet in France, gave to this view the completest of corroborations. These observations have been extended in Germany, America, and elsewhere; and although Binet and Janet worked independently of Myers, and did work far more objective, he nevertheless will stand as the original announcer of a theory which, in my opinion, makes an epoch, not only in medical but in psychological science, because it brings in an entirely new conception of our mental possibilities.
