有两种东西是无限的，宇宙和人类的愚蠢。

The best way to predict the future is to create it.

When men are most sure and arrogant they are commonly most mistaken， giving views to passion without that proper deliberation which alone can secure them from the grossest absurdities.

It seems to me that if you or I must choose between two courses of thought or action, we should remember our dying and try so to live that our death brings no pleasure to the world.

我们之所以能够感知事物的变化，是因为单子在无限的变化中保持了稳定的内在本质。
