The identification of the ego with consciousness robs it of contact with the unconscious and thus of psychic wholeness.  Consciousness can now claim to represent unity, but this unity is only the relative unity of the conscious mind and not that of the personality.  Psychic wholeness is lost and is replaced by the dualistic principle of opposites which governs all conscious and unconscious constellations.
