Nietzsche went further, for rather than embracing reason at the expense of faith he rejected any confidence in reason and truth. Moral values, in his view, "derived not from faith or reason but from a will to power." Morality was the "self-created life, free from any constraints of truth."
Whatever course of thought you choose to pursue begins with an act of faith. And if you decide to do without the constraints of truth, you’re opting for make-believe.
