Women, they have minds, and they have souls, as well as just hearts. And they've got ambition, and they've got talent, as well as just beauty. I'm so sick of people saying that love is just all a woman is fit for.
《三民主义.民生主义》（1924年8月10日）
I’m not a guy that’s going to shy away from the moment.
The mind is a continuous stream of events.
The truth is, the science of Nature has been already too long made only a work of the brain and the fancy: It is now high time that it should return to the plainness and soundness of observations on material and obvious things.
