The rule of recognition exists as a social fact.

抽象不仅仅是隐藏细节；它是关于创建问题域的清晰简洁的模型。

The challenge is to transform the constraints into opportunities.

I needed a drink, I needed a lot of life insurance, I needed a vacation, I needed a home in the country. What I had was a coat, a hat and a gun.

羊羔有跪下接受母乳的感恩举动，小乌鸦有衔食喂母鸦的情义。

自信不是来自永远正确，而是来自不怕犯错。
