How can the technique that makes it possible to break with the alienation maintained by the combined action of narcissism, ego-splitting and collective identifications be theorized? And how does analysis succeed in making consciousness work against itself? Between resexualization and masochism, and against the defensive function of reality-testing, the author envisages, by following Denise Braunschweig step by step, the path taken by symbolization to take possession of internal and external realities and to tolerate an ineliminable order of reality.
