自由比平等重要。实现平等的企图危及了自由。如果失去了自由，就连在不自由的人中间也不会有平等。

——〈在香港大学的演说〉（又名〈革命思想之产生〉），1923年2月19日

如果爵位不高，那么人民就不敬重他；如果俸禄不重，那么人民就不会信任他；如果在理事时没有决断权那么人民不会敬畏他。 

Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.

未来属于那些相信自己梦想之美的人。

下山比上山容易，但最好的视野在山顶。

国与国之间是平等的，人与人之间也是平等的，在人格与尊严上是没有贵贱之分的，上天对所有人都是一视同仁的，人生而平等是上天赋予每个人的不可被侵犯的权利。

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