词语如同影子，影子如同词语：它们什么都不说，它们只是重复我们想听的话。
Words are like shadows, and shadows are like words: they say nothing, they only repeat what we want to hear.
The market is an example of a spontaneous order: a system which is the product of human action but not of human design.
The novel is the art of the possible, and the possible is always more terrifying than the real.
——临终时对孔祥熙说，1925年3月
我们必须倾听科学，即使它挑战我们的传统方法。
