“There is only one solution if old age is not to be an absurd parody of our former life, and that is to go on pursuing ends that give our existence a meaning.”

Light (1919), Ch. XXIII - Face To Face
Context: When you look straight on, you end by seeing the immense event — death. There is only one thing which really gives the meaning of our whole life, and that is our death. In that terrible light may they judge their hearts who will one day die. Well I know that Marie's death would be the same thing in my heart as my own, and it seems to me also that only within her of all the world does my own likeness wholly live. We are not afraid of the too great sincerity which goes the length of these things; and we talk about them, beside the bed which awaits the inevitable hour when we shall not awake in it again. We say: —
"There'll be a day when I shall begin something that I shan't finish — a walk, or a letter, or a sentence, or a dream.".

Review of Selected Essays http://www.nybooks.com/articles/13783 by Simone Weil, The New York Review of Books (1 February 1963)
Context: Ours is an age which consciously pursues health, and yet only believes in the reality of sickness. The truths we respect are those born of affliction. We measure truth in terms of the cost to the writer in suffering — rather than by the standard of an objective truth to which a writer's words correspond. Each of our truths must have a martyr.

Review of Nausea by Jean-Paul Sartre, published in the newspaper Alger Républicain (20 October 1938), p. 5; also quoted in Albert Camus and the Philosophy of the Absurd (2002) by Avi Sagi, p. 43
Context: It is the failing of a certain literature to believe that life is tragic because it is wretched.
Life can be magnificent and overwhelming — that is its whole tragedy. Without beauty, love, or danger it would be almost easy to live. And M. Sartre's hero does not perhaps give us the real meaning of his anguish when he insists on those aspects of man he finds repugnant, instead of basing his reasons for despair on certain of man's signs of greatness.
The realization that life is absurd cannot be an end, but only a beginning. This is a truth nearly all great minds have taken as their starting point. It is not this discovery that is interesting, but the consequences and rules of action drawn from it.

The Tragic Sense of Life (1913), III : The Hunger of Immortality
Context: The vain man is in like cause with the avaricious — he takes the mean for the end; forgetting the end he pursues the means for its own sake and goes no further. The seeming to be something, conducive to being it, ends by forming our objective. We need that others should believe in our superiority to them in order that we may believe in it ourselves, and upon their belief base our faith in our own persistence, or at least in the persistence of our fame. We are more grateful to him that congratulates us on the skill with which we defend a cause than we are to him who recognizes the truth or goodness of the cause itself. A rabid mania for originality is rife in the modern intellectual world and characterizes all individual effort. We would rather err with genius than hit the mark with the crowd.
