哲学家的工作在于为特定目的汇集提醒。

The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.

We are all just echoes of something that once was.

教学的艺术是帮助发现的艺术。

The key to performance is elegance, not battalions of special cases.

你越努力，就越幸运。
