Few especially in this country realize that while Fre-udian themes have rarely found a place on the programs of the American Psychological Association they have att-racted great and growing attention and found frequent elaboration by students of literature history biography sociology morals and aesthetics anthropology educa-tion and religion. They have given the world a new con-ception of both infancy and adolescence and shed much new light upon characterology; given us a new and clea-rer view of sleep dreams reveries and revealed hitherto unknown mental mechanisms common to normal and pathological states and processes showing that the law of causation extends to the most incoherent acts and even verbigerations in insanity; gone far to clear up the terra incognita of hysteria; taught us to recognize morbid symp-toms often neurotic and psychotic in their germ; revealed the operations of the primitive mind so overlaid and rep-ressed that we had almost lost sight of them; fashioned and used the key of symbolism to unlock many mysti-cisms of the past; and in addition to all this affected tho-usands of cures established a new prophylaxis and sug-gested new tests for character disposition and ability in all combining the practical and theoretic to a degree salu-tary as it is rare.
