The significance of Kleinian contributions to psychoanalysis I. Kleinian instinct theory.Int J Psychoanal Psychother. 1980-1981; 8:375-92.IJ
The history of Freud's instinct theory shows that it ambiguously contains two separate roots of developments; one, the nutritional-transactional, and the other, the autoerotic discharge model. The former is the forerunner of Klein's instinct theory and the latter is considered classical theory. Kleinians and Freudians have not fully understood that each holds an instinct theory which is quite different from the other. The consequences of this theoretical dialectic are of great importance in distinguishing the Kleinian theory of fantasy from the Freudian theory of fantasy, the theory of repression, the theory of the unconscious, and ultimately the theory of the internal world.
