保守秘密的最好方法是永远不要有秘密。

格雷厄姆-多德都市的超级投资者们－巴菲特1984哥伦比亚大学的演讲

The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.

好奇心驱动科学，但道德必须引导它。

没有自由，美德就无法存在。

I don’t really have studios. I wander around around people’s attics, out in fields, in cellars, anyplace I find that invites me.

失败是有教益的。真正思考的人从失败中学到的东西和从成功中学到的一样多。
