The great struggle of the twentieth century was between liberalism and totalitarianism.

我是一个活得很谨慎的，很多人在互联网上所听到我嚣张跋扈的一面，不知道我做事还有勇有谋。

罗永浩

哗啦哗啦把自己的事业讲给大家听的人，它的价值一定是毫不足道的。切实苦干的人往往不是高谈阔论的，他们惊天动地的事业显示了他们的伟大，可是在筹划重大事业的时候，他们是默不作声的。

永远快乐这句话，不但渺茫得不能实现，并且荒谬得不能成立。快过的决不会永久；我们说永远快乐，正好像说四方的圆形，静止的动作同样地自相矛盾。

钱钟书

Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.

你们的聪明才智必定会派上用场，因为你们将在一片充满奇迹的土地上行进。我们人类，尽管跬步前行，却终将令自己大吃一惊。我们能够想方设法制造清洁能源，也能够一个原子一个原子地组装微型机械，使之穿过细胞壁，然后修复细胞。这个月，有一个异常而不可避免的事情发生了——人类终于合成了生命。在未来几年，我们不仅会合成生命，还会按说明书驱动它们。我相信你们甚至会看到我们理解人类的大脑，儒勒·凡尔纳，马克·吐温，伽利略，牛顿——所有那些充满好奇之心的人都希望能够活到现在。作为文明人，我们会拥有如此之多的天赋，就像是坐在我面前的你们，每一个生命个体都拥有许多独特的天赋。
