爱不是用来理解的，而是用来感受的。

——赠宋庆龄题词，1922年

Kindness is the language which the deaf can hear and the blind can see.

We are all born with a certain package. We are who we are: where we were born, who we were born as, how we were raised. We're kind of stuck inside that person, and the purpose of civilization and growth is to be able to reach out and empathize a little bit with other people.

教学的全部艺术，不过是唤醒年轻人天生的好奇心，以便日后满足它。
