我们是生存机器——盲目编程的机器人载体，目的是保存被称为基因的自私分子。
We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes.
出自汉·桓宽《盐铁论·地广》。释义：不因为是自己的亲近就给以重赏；也不因为与自己疏远就忘掉给人恩惠。
Happiness ain't a thing in itself --- it's only a contrast with something that ain't pleasant. That's all it is.
