" But if man is free to define for himself the conditions of a life which is valid in his own eyes, can he not choose whatever he likes and act however he likes? Dostoievsky asserted, “If God does not exist, everything is permitted.” Today’s believers use this formula for their own advantage. 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, and his victories as well. "
