Pathology has made us acquainted with a great number of states in which the boundary lines between the ego and the external world become uncertain or in which they are actually drawn incorrectly. There are cases in which parts of a person's own body, even portions of his own mental life - his perceptions, thoughts and feelings -, appear alien to him and as not belonging to his ego; there are other cases in which he ascribes to the external world things that clearly originate in his own ego and that ought to be acknowledged by it.

Sigmund FreudOur unconscious, then, does not believe in its own death; it behaves as if it were immortal. It knows nothing that is negative; in it contradictories coincide. This may be the secret of heroism.
