Intelligence will be used in the service of the neurosis.

A man should not strive to eliminate his complexes but to get into accord with them: they are legitimately what directs his conduct in the world.

The conscious mind may be compared to a fountain playing in the sun and falling back into the great subterranean pool of subconscious from which it rises.

What good to us is a long life if it is difficult and barren of joys, and if it is so full of misery that we can only welcome death as a deliverer?

The aim of psychoanalysis is to relieve people of their neurotic unhappiness so that they can be normally unhappy.
