The Shadow is a moral problem that challenges the whole ego-personality, for no one can become conscious of the shadow without considerable moral effort. To become conscious of it involves recognizing the dark aspects of the personality as present and real. This act is the essential condition for any kind of self-knowledge, and it therefore, as a rule, meets with considerable resistance. Indeed, self-knowledge as a psychotherapuetic measure frequently requires much painstaking work extending over a long period of time.
Carl JungI can still recall vividly how Freud said to me, "My dear Jung, promise me never to abandon the sexual theory. That is the most essential thing of all. You see, we must make a dogma of it, an unshakable bulwark" ... In some astonishment I asked him, "A bulwark-against what?" To which he replied, "Against the black tide of mud"-and here he hesitated for a moment, then added of occultism.
