Friedrich Nietzsche,
Selected Letters of Friedrich Nietzsche
“ This has been a time during which you have yourself tested the truth of Schopenhauer's doctrine. If the fourth book of his principal work now makes a disagreeable, gloomy, and tedious impression upon you; if it has not the power to bear you triumphantly beyond all the terrible outward pain into that sweetly melancholy but happy mood which possesses us at the sound of lofty music, into that mood in which one sees one's earthly shell fall from one, then it is possible that even I, too, may have nothing more to do with his philosophy. ”
