A transference neurosis corresponds to a conflict between ego and id, a narcissistic neurosis corresponds to that between between ego and super-ego, and a psychosis to that between ego and outer world.
Sigmund FreudThe expectation that every neurotic phenomenon can be cured may, I suspect, be derived from the layman's belief that the neuroses are something quite unnecessary which have no right whatever to exist. Whereas in fact they are severe, constitutionally fixed illnesses, which rarely restrict themselves to only a few attacks but persist as a rule over long periods throughout life.
Sigmund FreudMans most disagreeable habits and idiosyncrasies, his deceit, his cowardice, his lack of reverence, are engendered by his incomplete adjustment to a complicated civilisation. It is the result of the conflict between our instincts and our culture.
