"The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."
自由不是让你想做什么就做什么,自由是教你不想做什么,就可以不做什么。
Innovation and technology will be key to solving the energy challenges we face.
最好的艺术是慷慨的。
使较弱的论点变得更强。
——〈在广州岭南学堂的演说〉,1912年5月7日
仁爱的人爱护他人,正义的人遵循道理。
