我很喜欢圣奥古斯丁在“上帝之城”里的一句话，他说“以社会地位评价人是一种罪”。用现在的口吻说，看一个人的名片来决定你是否要和他交谈是罪。对圣奥古斯丁来说，人的价值不在他的社会地位，只有神可以决定一个人的价值，他将在天使围绕、小号奏鸣，天空破开的世界末日给于最后审判，如果你是像我一样的世俗论者，这想法太疯狂了，但这想法有它的价值。

知识的真正方法是实验。

You’ve got to have models in your head. And you’ve got to array your experience—both vicarious and direct—on this latticework of models. You may have noticed students who just try to remember and pound back what is remembered. Well, they fail in school and in life. You’ve got to hang experience on a latticework of models in your mind.

The past is never dead. It's not even past.

艺术不是你看到的，而是你让别人看到的。
