_A subconscious process may be provisionally defined as one of which the personality is unaware, which, therefore, is outside the personal consciousness, and which is a factor in the determination of conscious and bodily phenomena, or produces effects analogous to those which might be directly or indirectly induced by consciousness._ It would be out of the question at this time to enter into an exposition of the larger subject—the multiform phenomena of the subconscious, but as its processes are fundamental to an understanding of many phenomena with which we shall have to deal, we should have a clear understanding of the grounds on which such processes are postulated as specific, concrete occurrences. The classical demonstration of subconscious occurrences makes use of certain phenomena of hysteria, particularly those of subconscious personalities and artificial “automatic” phenomena like automatic writing. The epoch-making researches of Janet[75] on hysterics and almost coincidently with him of Edmund Gurney on hypnotics very clearly established the fact that these phenomena are the manifestations of _dissociated_ processes outside of and independent of the personal consciousness. Among the phenomena, for example, are motor activities of various kinds such as ordinarily are or may be induced by conscious intelligence. As the individual, owing to anesthesia, may be entirely unaware even that he has performed any such act, the process that performed it must be one that is subconscious.
