The notion of ambiguity must not be confused with that of absurdity. To declare that existence is absurd is to deny that it can ever be given a meaning; to say that it is ambiguous is to assert that its meaning is never fixed, that it must be constantly won. Absurdity challenges every ethics; but also the finished rationalization of the real would leave no room for ethics; it is because man's condition is ambiguous that he seeks, through failure and outrageousness, to save his existence.
