No one can doubt the existence of the unconscious. It is there all right. The question is what it contains. Is it only the seat of animal nature, of instinct, the libidinal forces, or does it also contain elements of higher life? Does the human need for truth, for instance, also have roots in the unconscious? Why, since the unconscious is by definition what we do not know, should we not expect to find in it traces of the soul as well as of aggression?
