“Wherever morality is based on theology, wherever the right is made dependent on divine authority, the most immoral, unjust, infamous things can be justified and established. I can found morality on theology only when I myself have already defined the Divine Being by means of morality. In the contrary case, I have no criterion of the moral and immoral, but merely an unmoral, arbitrary basis, from which I may deduce anything I please. Thus, if I would found morality on God, I must first of all place it in God: for Morality, Right, in short, all substantial relations, have their only basis in themselves, can only have a real foundation—such as truth demands—when they are thus based. (…) Where man is in earnest about ethics, they have in themselves the validity of a divine power. If morality has no foundation in itself, there is no inherent necessity for morality; morality is then surrendered to the groundless arbitrariness of religion.”
