数学之美在于它能够揭示看似复杂事物背后的简单性。

The concept of purpose has no place in a scientific account of behavior.

I can't go on, I'll go on.

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

The world is full of people whose notion of a satisfactory future is, in fact, a return to the idealised past.

在我看来，一种信仰只是一个信仰现象，信仰的内容无足轻重。

永远不要满足于现状，始终追求更好。

Nothing has really happened until it has been recorded.
