马克吐温说过
任何人都可以说谎：单纯的谎言是没有价值的，
它必须有艺术性，
它必须表现出一种灿烂的、可以相信和令人信服的可能性，
也就是说，它必须深思熟虑地算计。
Anybody can tell lies: there is no merit in a mere lie,
it must possess art,
it must exhibit a splendid, plausible, and convincing probability,
that is to say, it must be powerfully calculated to deceive.
马克吐温又说
有869种不同形式的说谎，
但其中只有一种是完全被禁止的。
你不应该对你的邻居作伪证。
There are 869 different forms of lying,
but only one of them has been squarely forbidden.
Thou shalt not bear false witness against thy neighbor.
好吧，我原谅你，因为我也说谎，
但是能够请你多用点心，深思熟虑好吗？
