"A book is a small miracle."

愛する人を守るために、人は強くなれる。

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

概率论是唯一可用的数学工具，用于帮助映射未知和不可控的事物。

人的命运在他的灵魂中。

The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.

说话有分寸则少得罪人；行为有节制则少悔恨；爱慕有节制则要求少；快乐有节制则祸败少；饮食有节制则疾病少。

I disapprove of what you say， but I will defend to the death your right to say it.
