War is the father of all, and king of all; and some he has made gods, and some men; some he has made slaves, and some free.

You must take personal responsibility. You cannot change the circumstances, the seasons, or the wind, but you can change yourself.

——《在沪举办茶话会上的演说》（1916年7月17日）

迈向未知的每一步，都是理解世界和理解自己的一步。
