When one gives up the Christian faith, one pulls the right to Christian morality out from under one's feet. This morality is by no means self-evident. Christianity is a system, a whole view of things thought out together. By breaking one main concept out of it, the faith in God, one breaks the whole. It stands or falls with faith in God.
Friedrich NietzscheThere is not enough love and goodness in the world to permit giving any of it away to imaginary beings.
Friedrich NietzscheWe have to learn how to come out of unclean situations cleaner than we were, and even how to wash ourselves with dirty water whenwe need to.
Friedrich NietzscheMorality is neither rational nor absolute nor natural. World has known many moral systems, each of which advances claims universality; all moral systems are therefore particular, serving a specific purpose for their propagators or creators, and enforcing a certain regime that disciplines human beings for social life by narrowing our perspectives and limiting our horizons.
Friedrich Nietzsche
