Who said “Our true nationality is mankind.”?

“No human race is superior; no religious faith is inferior. All collective judgments are wrong. Only racists make them.”

“As you grow older, you'll see white men cheat black men every day of your life, but let me tell you something and don't you forget it -- whenever a white man does that to a black man, no matter who he is, how rich he is, or how fine a family he comes from, that white man is trash.”

“Racism? But isn't it only a form of misanthropy?”

“I wasn't always black... There was this freckle, and it got bigger and bigger.”

“The worst mistake I made was that stupid, suburban prejudice of anti-Semitism.”

“Cynicism is humour in ill health.”

“Cycle tracks will abound in Utopia.”

“Moral indignation is jealousy with a halo.”

“The crisis of yesterday is the joke of tomorrow.”

“Fools make researches and wise men exploit them.”

“Adapt or perish, now as ever, is Nature's inexorable imperative.”
