Three passions， simple but overwhelmingly strong， have governed my life: the longing for love， the search for knowledge， and unbearable pity for the suffering of mankind.

The human being is a sun; and the senses are his planets.

The key to a happy life is not in avoiding problems, but in learning how to deal with them effectively.

历史不是过去。历史就是现在。我们随身携带着历史。

在沉默中，和惶恐不安作斗争。

天下的一切事物不可以没有标准，做人要有做人的标准，即原则；做事要有做事的标准，即规则；治国要有治国的标准，即法则。不遵循一定的标准而能成事者，自古以来是没有的。
