The form of autobiographical writing, is, to varying degrees, in many modern contemporary writers, especially women. For various reasons, the fundamental question that arises is: these autobiographical narratives, are they sincere? The author is not obliged to include occasionally, for reasons of modesty, of imaginary elements, not excluding even the lie? In fact, it’s what Marguerite Duras had confirmed: “In Moderato Cantabile, I tried to tell a secret experience. Then arose a problem of shame. I built walls around this experience. And I wrapped the ice … I’m hidden behind Moderato Cantabile much behind my other books. It is also one of my books which we made many mistakes! . The statement said the author’s wishes to invite the reader to read his novels, not only as referring to a fictional truth of human nature, but also as “fantasies” indicative of an individual. Why the writing of Marguerite Duras has often been defined as a common place between reality and fiction. Our intention is to study through three of his novels: Un Barrage contre le Pacifique, L’Amant and L’Amant de la Chine du Nord, the duracien autobiographical. Identify strategies and the challenge of such a practice that endangers the possibility of fiction, but also to understand how this fiction persists to emerge and make sense.
