I love man as my fellow; but his scepter, real, or usurped, extends not to me, unless the reason of an individual demands my homage.
我爱人类作为我的同胞；但他的权杖，无论是真实的还是篡夺的，除非个人的理性要求我致敬，否则不会延伸到我。
在桂林学界迎会的演说，1922年1月22日

If you get up in the morning and think the future is going to be better, it is a bright day. Otherwise, it's not.
【译文】 孔子说：“《关雎》这篇诗，快乐却不淫秽，悲哀却不伤痛。”
