The stranger is close to us, insofar as we feel between him and ourselves common features of a national, social, occupational, or generally human, nature. He is far from us, insofar as these common features extend beyond him or us, and connect us only because they connect a great many people.

——温铁军2002年6月温铁军在清华大学的一次讲座

The only limit to our realization of tomorrow is our doubts of today.

【释义】心境不清明，就无法领悟正道；志向不坚定，就无法成就事业。

最崇高的行为是将他人置于自己之前。
