Without the errors which are active in every psychical pleasure and displeasrue a humanity would never have come into existence--whose fundamental feeling is and remains that man is the free being in a world of unfreedom, the external miracle worker whether he does good or ill, the astonishing exception, the superbeast and almost-god, the meaning of creation which cannot be thought away, the solution of the cosmic riddle, the mighty ruler over nature and the despiser of it, the creature which calls its history world history!--Vanitas vanitatum homo.
Friedrich Nietzsche, A Nietzsche Reader
humanity, vanity
