我们都是自己过去的幽灵，徘徊在我们曾经熟悉的地方。

可持续性不是一种选择；它是我们对后代的责任。

诗歌是捕捉短暂之物的艺术。

The business of education is not to make the young perfect in any one of the sciences, but so to open and dispose their minds as may make them capable of any, when they shall apply themselves to it.

The surest way to corrupt a youth is to instruct him to hold in higher esteem those who think alike than those who think differently.
