To re-establish man at the heart of his destiny is, they claim, to repudiate all ethics. However, far from God's absence authorizing all license, the contrary is the case, because man is abandoned on the earth, because his acts are definitive, absolute engagements. He bears the responsibility for a world which is not the work of a strange power, but of himself, where his defeats are inscribed, & his victories as well.
Simone de Beauvoir, The Ethics of Ambiguity
