With his position on the unconscious, Freud taught us how each of us had a personality we were unaware of, an unconfessed projection of our conscious "self." He vividly showed us the secret face of our other "Ego," taught us how this cursed brother we do not want to recognize was formed and developed, but which group psychology had recorded for centuries in the myth of the "double." This second Ego, burdened with guilt, repressed into the darkness of oblivion, -yet always alive, dictating our actions without our knowledge- makes us "volens nolens" brothers of the most backward primitive, the most ruthless criminal, the most passionate neurotic. We are not dealing with an idea of moral brotherhood, but with a biological fact. By revealing to us an internal destiny that replaces the external Fate of ancient tragedy, explaining to us how and why the drama of Oedipus and Hamlet is played out within all of us, Freud gave us a new perspective on our human destiny.
