“There's no end to the absurd things people will do trying to make life mean something.”

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.

Context: The "mountain-sea" spirit means that it is bad to repeat the same thing several times when fighting the enemy. There may be no help but to do something twice, but do not try it a third time. If you once make an attack and fail, there is little chance of success if you use the same approach again.
