数学的艺术在于发现包含所有普遍性萌芽的特殊案例。

当涉及人类尊严时，我们不能妥协。

The truth is that in America, the Jew is a figment of the Christian imagination.

不要担心你在数学上遇到的困难；我敢保证我遇到的困难比你还大得多。

The wise seek happiness within their own souls, while fools search outside.

减少思虑，来调养心气；减少性欲来调养肾气；不要妄动，来调养骨气；戒止嗔怒，来调养肝气；饮食素淡，来调养胃气；减少话语，来调养神气；博鉴群书，来调养胆气；顺应时令，来调养元气。

Abundance is not something we acquire. It is something we tune into.

True leadership inspires others to achieve more than they thought possible.
