ABSTRACT
A woman of foreign origins, who had been living in France for several years, reported during a session a conversation that she had had with one of her female friends on the subject of her expatriation dating back many years. The reasons that can drive a subject to leave, to alienate himself, to avoid what he loves all raise questions for psychoanalysis. In his seminar on the ethics of psychoanalysis, Jacques Lacan takes up Freud's considerations on the prohibition against incest: Freud designates the prohibition of incest as the underlying principle of the primordial law, the law of which all other cultural developments are no more than the consequences and the ramifications. The pleasure principle is defined by Freud as one of the principles that governs the functioning of mental activity and aims to avoid the unpleasure that can result from excessive excitation.
