"From the very beginning, existentialism defined itself as a philosophy of ambiguity. It was by affirming the irreducible character of ambiguity that Kierkegaard opposed himself to Hegel, and it is by ambiguity that, in our own generation, Sartre, in Being and Nothingness, fundamentally defined man, that being whose being is not to be, that subjectivity which realizes itself only as a presence in the world, that engaged freedom, that surging of the for-oneself which is immediately given for others. But it is also claimed that existentialism is a philosophy of the absurd and of despair. It encloses man in a sterile anguish, in an empty subjectivity. It is incapable of furnishing him with any principle for making choices. Let him do as he pleases. In any case, the game is lost. Does not Sartre declare, in effect, that man is a “useless passion,” that he tries in vain to realize the synthesis of the for-oneself and the in-oneself, to make himself God? It is true. But it is also true that the most optimistic ethics have all begun by emphasizing the element of failure involved in the condition of man; without failure, no ethics; for a being who, from the very start, would be an exact co-incidence with himself, in a perfect plenitude, the notion of having-to-be would have no meaning. One does not offer an ethics to a God. It is impossible to propose any to man if one defines him as nature, as something given. The so-called psychological or empirical ethics manage to establish themselves only by introducing surreptitiously some flaw within the manthing which they have first defined."

“She was beautiful, with a beauty so severe and so solitary that at first it was startling. "Ah! If only there were two of me," she thought, "one doing the talking and one listening, one living and one watching, how I would love myself. I'd envy no one."”

“Insects were scurrying about in the shade cast by the grass, and the lawn was a huge monotonous forest of thousands of little green blades, all equal, all alike, hiding the world from each other. Anguished, she thought, "I don't want to be just another blade of grass."”

“[T]he Sahara was a spectacle as alive as the sea. The tints of the dunes changed according to the time of day and the angle of the light: golden as apricots from far off, when we drove close to them they turned to freshly made butter; behind us they grew pink; from sand to rock, the materials of which the desert was made varied as much as its tints.”

“But presently I began to bubble with happiness. No, my daughters' absence did not sadden me at all—quite the reverse. I could drive as fast or as slowly as I liked, go where I liked, stop when the whim took me. I made up my mind to spend the week wandering about. I get up as soon as it is light. The car is waiting for me in the street or in the courtyard like a faithful animal; it is wet with dew; I wipe its eyes, and full of delight I tear away through the growing sunlight.”

“What is an adult? A child puffed with age.”

“Il n'y a pas de mort naturelle: rien de ce qui arrive à l'homme n'est jamais naturel puisque sa présence met le monde en question. Tous les hommes sont mortels: mais pour chaque homme sa mort est un accident et, même s'il la connaît et y consent, une violence indue.”
