Speaking of his autobiography in a 1985 interview with The Paris Review:

INTERVIEWER

Some people like the theory of literature contained in the book above all.

ROBBE-GRILLET

Indeed! Which is the continuation of what is in my novels and my theoretical works. None of these points is indifferent to me, at the same time none really interests me. What does interest me is the weaving of all these different elements in the book; the way they mix in movement, constantly shifting and changing, as if they were fragments of me. When I think of myself, I feel that I am made up of fragments in which there are childhood memories, fictional characters I particularly care about—such as Henri de Corinth—and even characters who belong to literature and with whom I feel I have family ties. Stavrogin of The Possessed and Madame Bovary are related to me exactly as my grandfather is, or my aunt. So it is the way all these figures move and refuse to be fixed that excites me. Well, at least that is what I say today. Another day I might say something different!

I am certain that a novelist is someone who attributes a different reality-value to the characters and events of his story than to those of “real” life. A novelist is someone who confuses his own life with that of his characters.
