Retracing the main common aspects between the anthropological thought and the psychoanalytic one, in this paper we will further discuss about the main common points between the notions of unconscious according to Carl Gustav Jung and Claude Lévi-Strauss, taking into account the Erich Neumann thought. On the basis of very simple elementary logic considerations centered around the basic notion of separation of opposites, what will be said might turn out to be useful for some speculations upon possible origins of the rational thought, hence for the origins of consciousness.
