This article intends to demonstrate a displacement in Lacan's conception on the Ethics, using a comparison between the perspectives of The Seminar, book 7: the ethics of psychoanalysis and of The Seminar, book 20: on feminine sexuality, the limits of love and knowledge: encore. While the first perspective privileges the organization of a symbolic Law - and this one, if trespassed, culminates in the approach of an impossible jouissance (enjoyment) to das Ding - the latter emphasizes the jouissance of the body as something that is not-all organized by the symbolic. Therefore, there is a movement from an ethics of breach, which aims at a point beyond the pleasure principle and of the service of goods, to an ethic where the addition of the pleasure principle invades the field since the beginning. The logic of contingency is how Lacan intends to formalize a manner of making the symbolic necessity and the impossibility of the desire to register in the records of the contingent and the possible.
