Freud and Jung: the creation of the psychoanalytic universe

How can we think about or imagine the psychoanalytic universe in which we work, think, organise and speak? How can we make sense of a universe of discourse that includes id psychology, object relations, neuropsychoanalysis and existential analysis, and all of the Freudian, Jungian, Kleinian, Lacanian and Kohutian tendencies and their neo- and post- versions? What sort of historiography will help us to orient ourselves? Is there an approach to the history of psychoanalysis that will serve the interests of historical accuracy and heuristic possibility?
