ABSTRACT
The propensity of the mind for conflict was a major concept in Freud's theorizing that is, a dynamic system with an inherent tendency toward an inner organization of forces that oppose and balance each other. Freud's earliest topographic model did not consist merely of a Preconscious and an Unconscious with a repressive barrier between them, but also included a biological parallel or analogy between sexual drives and ego drives. Freud visualized the Unconscious as full of pleasure-seeking drives that have a race-preservative function, whereas the Preconscious contains self-preservative drives that attempt to assure the individual's survival. It is not a psychological but a biological theory, although it can be viewed as a precursor of Freud's later theory: oedipal incestuous wishes versus castration fear. The development in Freud's concepts of structural topography was his growing understanding of infantile sexuality its nature as a very pleasure-seeking set of feelings and drives.
