Superid and Psyche

The Superid is not one drive among others in the Id, it is the very Psyche itself.  It is the fundamental Species-principle, e. g. Will to Live, Will to Power, Will to Evolve, etc., localized in one of its members.  Accordingly, Freud's main structures are three general intra-Psychic functions.  The Id is localized modes of the principle, e. g. nutrition, reproduction, etc.  The Ego unifies the manifold of the drives in the Id.  The Superego coordinates the Ego with other Egos, i. e. integrates it with society.  Thus, Conscience is fundamentally the Superid, and not necessarily the Superego--it can be the voice of society, as well as, as Heidegger conceives it, that of one's Ego.  Thus, since social formations are contingent, so, too, are the contents of the Superego--not only ideological norms, but taboos such as that of incest, as well.   Likewise uncertain is whether any of Freud's familiar objects of Psychoanalytic interest is more than a contingent condition.
