It is not when truth is dirty, but when it is shallow, that the lover of knowledge is reluctant to step into its waters. - Friedrich Nietzsche

if you are unwilling to endure your own suffering even for an hour, and continually forestall all possible misfortune, if you regard as deserving of annihilation, any suffering and pain generally as evil, as detestable, and as blots on existence, well, you have then, besides your religion of compassion, yet another religion in your heart (and this is perhaps the mother of the former)-the religion of smug ease. Ah, how little you know of the happiness of man, you comfortable and good-natured ones! For happiness and misfortune are brother and sister, and twins, who grow tall together, or, as with you, remain small together!
