We are more pained when one of our friends is guilty of something shameful than when we do it ourselves.
Friedrich NietzscheSo far there has been no philosopher in whose hands philosophy has not grown into an apology for knowledge; on this point, at least, every one is an optimist, that the greatest usefulness must be ascribed to knowledge. They are all tyrannized over by logic, and this is optimism in its essence.
Friedrich Nietzsche
