Contemporary psychoanalysis emphasizes the role of “real” trauma, as it is well shown by recent sociological and theoretical developments (such as Kohut's Self psychology, object relation theory, renewed interest in Ferenczi's and Sullivan's contributions, etc.). To understand more clearly these developments, the author traces again the steps laid down by Freud in building the psychoanalytic edifice. The renewed interest in the environment, in real traumas, and in the vicissitudes of object relations could be a “paradigm change” in psychoanalysis: a return to Freud's original seduction theory. This development is seen as related to the difficulties of Freud's drive theory.
