2. In consequence of this principle of systematization it is in our power by educational suggestion in hypnosis to organize mental processes and _build complexes_ of the same kind and in the same way as when the subject is awake. In fact, it is more readily done, inasmuch as in hypnosis the critical judgment and reflection tend to be suspended. The suggested ideas are accepted and education more easily accomplished. While in hypnosis the individual may thus be made to accept and hold new beliefs, new judgments, in short, new knowledge.[152] After waking he may or may not remember his hypnotic experiences. Generally he does. If he does the new knowledge, if firmly organized (by repetition and strong affective tones) is still retained, and if accepted (i.e., not repressed by conflicting ideas) shapes his views and conduct in accordance therewith. Even if his hypnotic experiences are not remembered, they still belong to his personality, inasmuch as they are neurographically conserved, and, experience shows, may still influence his stream of consciousness. His views are modified by his unconscious personality. His ideas may and generally do awaken the neurograms of associated systems created in hypnosis. Not remembering the hypnotic state as a whole he does not remember the _origin_ of his new knowledge; that is all. One point to be borne in mind is that conserved ideas, whether we can recall them or not, so long as they are conserved are a part of our personality, as I have previously pointed out, and ideas can emerge from the unconscious into the field of the conscious though we have completely forgotten their origin. It requires but a single experiment in the induction of suggested post-hypnotic phenomena to demonstrate these principles. 3. As to those _pathological states_ where there is a splitting of personality—hysterical crises, psycholeptic attacks, trance states, certain types of epilepsy, etc.—complexes may similarly be formed in them. In these conditions there is a dissociation of a large part of the normal mental life, and that which is left is only a limited field of consciousness. A new synthesis comes into being out of the unconscious to represent the personal self. Though the content of consciousness is a reproduction of, or determined by certain previous experiences, it is also true that in these states new experiences may result in new complexes which then take part in the personality as with hypnotic experiences.
