"Because you said nothing about a bear when you repeated your orders. You spoke only once of a bear. Everything else you spoke of twice. I thought you had changed your mind about the bear."[51] [51] Dr. Liégeois's account of his many hypnotic experiments, as given in his "De la Suggestion et du Somnambulisme dans leurs Rapports avec la Jurisprudence et la Médecine légale," forms one of the most striking contributions to the literature of hypnotism. Obviously, the hypnotic self, distinct and different though it is from the primary, waking self, can reason, can analyze, can draw conclusions as readily as the conscious self, and is, to put it otherwise, as truly a self as the conscious self. Facts like these, as was said, have caused numerous investigators to question the validity of the hitherto prevailing view of human personality. The self, they affirm, is no single, continuous, permanent entity. On the contrary, it is merely a loosely coördinated aggregation of mental states, forever shifting and changing, so that the self of to-morrow may be vastly different from the self of to-day. To quote Professor Ribot, the famous scientist, and one of the most distinguished exponents of this new view of the self: "The unity of the ego is not the unity of a single entity diffusing itself among multiple phenomena; it is the coördination of a certain number of states perpetually renascent, and having for their sole, common basis the vague feeling of the body. This unity does not diffuse itself downward, but is aggregated by ascent from below; it is not an initial, but a terminal point." And Ribot adds emphatically: "It is the organism, with the brain, its supreme representative, which constitutes the real personality; comprising in itself the remains of all that we have been and the possibilities of all that we shall be. The whole individual character is there inscribed, with its active and passive aptitudes, its sympathies and antipathies, its genius, its talent or its stupidity, its virtues and its vices, its torpor or its activity."[52] [52] Ribot's "Les Maladies de la Personalité."
