Man's task is to become conscious of the contents that press upward from the unconscious.

Nobody can fall so low unless he has a great depth. If such a thing can happen to a man, it challenges his best and highest on the other side; that is to say, this depth corresponds to a potential height, and the blackest darkness to a hidden light.

It is on the whole probably that we continually dream, but that consciousness makes such a noise that we do not hear it.

Our heart glows, and secret unrest gnaws at the root of our being. Dealing with the unconscious has become a question of life for us.

Nothing is more repulsive than a furtively prurient spirituality; it is just as unsavoury as gross sensuality.

In fact, the whole of mythology could be taken as a sort of projection of the collective unconscious

Dream analysis stands or falls with [the hypothesis of the unconscious]. Without it the dream appears to be merely a freak of nature, a meaningless conglomerate of memory-fragments left over from the happenings of the day.
