. The superego contains the socialisation that takes place during childhood. If it complements the id's instincts, the organism remains mentally healthy – the 'rider' carries out the will of his 'animal' "as if it were his own." The borders between un- and consciousness aren't sharp: "Where id was, ego shall become."In order to overcome difficulties of understanding as far as possible, Freud formulated his "metapsychology" which for Lacan represents a
technical elaboration of the concepts of the soul model: dividing the organism into three instances the id is regarded as the germ from which the ego and the superego develop. Driven by an energy that Freud calls
libido in direct reference to Plato's
Eros, the instances complement each other through their specific functions in a similar way to the
organelles of a cell or parts of a technical apparatus. Further distinctions (as the coordinates of
topology,
dynamics and
economy) encouraged Freud to assume that the metapsychological elaboration of the structural model would make it fully compatible with biological sciences such as evolutionary theory and enable a well-founded concept of mental health including a theory of human development, which naturally completed in three successive stages: the oral, anal and genital phase. However, as important as this is for the diagnostic process (illness can only be realised as a deviation from the optimal cooperation of all psycho-organic functions), Freud had to be modest. He came to the conclusion that he had to leave his metapsychological-based model of the soul in the unfinished state of a
torso because – as he stated one last time in
Moses and Monotheism – there was no well-founded
primate research in the first half of 20th century. Without knowledge of the instinctive social behaviour with the corresponding structure of cohabitation of our genetically
closest relatives in realm of primates, Freud's thesis of Darwin's primordial horde (as presented for discussion in
Totem and Taboo) can't be tested and, if possible, replaced by a realistic model. Horde life and its violent abolition through the introduction of monogamy (as an agreement between the sons who murdered the horde's polygamous father) embody the evolutionary as well as cultural-prehistorical core of psychoanalysis. It stands in contrast to the religiously enigmatic reports about the origin of
monogamous couples on earth as an expression of divine will, but closer to the ancient trap to pacify political conflicts among the groups of Neolithic mankind. (See
Prometheus' uprising against Zeus, who created
Pandora as a fatal wedding gift for Epimetheus to divide and rule these titanic brothers; Plato's myth of spherical men cut into isolated individuals for the same reason; and the similarly resolved revolt of inferior gods in the Flood epic
Atra-Hasis). Additional important assumptions are based on it, such as the
Oedipus complex, the origin of moral-totemic rules like
Incest taboo and, not least, Freud's
Civilization and Its Discontents. Nonetheless, due to the lack of ethological primate research, these ideas remained an unproven belief of palaeo-anthropological science – only a
hypothesis or "
just so story as a not unpleasant English critic wittily called it. But I mean it honours a hypothesis if it shows the capability of creating context and understanding in new areas." == Structural model and neuropsychoanalysis ==
