历史是一场我试图从中醒来的噩梦。

不是关于成为最好的，而是关于比昨天的自己更好。

The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence which at a given instant comprehends all the relations of the entities of this universe, it could state the respective positions, motions, and general effects of all these entities at any time in the past or future.

活着就是为了改变世界，难道还有其他原因吗？
