水和空气，所有生命赖以生存的两种基本流体，已经变成了全球的垃圾箱。

沉默可以是最响亮的抗议形式。

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.

爱不是安慰，它是光明。

——致书蒋介石，1920年10月29日

The thing about smart people is that they seem like crazy people to dumb people.

Courage is resistance to fear, mastery of fear - not absence of fear.
