"The more we learn, the more we realize how much we don't know."

始終追求卓越，而不是完美。

我們都是我們選擇的總和，有時也是他人選擇的總和。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

每本書都是作者首先要獨自經歷的旅程。
