“No state would ever dare to patronize such men as Plato and Schopenhauer. And why? Simply because the state is always afraid of them. They tell the truth.… Consequently, the man who submits to be a philosopher in the pay of the state must also submit to being looked upon by the state as one who has waived his claim to pursue the truth into all its fastnesses. So long as he holds his place, he must acknowledge something still higher than the truth — and that is the state.…”
Friedrich Nietzsche, “Schopenhauer als Erzieher,” as translated by H. L. Mencken, The Philosophy of Friedrich Nietzsche (Third Edition, 1913), Chapter XII, Education.
