"[...]Schopenhauer, although a pessimist, ACTUALLY—played the flute... daily after dinner: one may read about the matter in his biography. A question by the way: a pessimist, a repudiator of God and of the world, who MAKES A HALT at morality—who assents to morality, and plays the flute to laede-neminem morals, what? Is that really—a pessimist?
—the skepticism of daring manliness, which is closely related to the genius for war and conquest, and made its first entrance into Germany in the person of the great Frederick. This skepticism despises and nevertheless grasps; it undermines and takes possession; it does not believe, but it does not thereby lose itself; it gives the spirit a dangerous liberty, but it keeps strict guard over the heart." - Friedrich Nietzsche, Beyond Good and Evil
What Nietzsche neglects to mention is that Frederick also played the flute. What instrument does a pessimist play? (Do pessimists even play music?)
