Full context:   In Beyond Good and Evil, Friedrich Nietzsche describes master–slave morality, in which a noble man regards himself as a "determiner of values"; one who does not require approval, but passes judgment. Later, in the same text, he lists man's four virtues as courage, insight, sympathy, and solitude, and goes on to emphasize the importance of courage: "The great epochs of our life are the occasions when we gain the courage to re-baptize our evil qualities as our best qualities."
