一个理论的前提越简单，它关联的不同事物越多，其适用范围越广，这个理论就越令人印象深刻。
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.
I don't fear failure. I fear not trying.
最好的报复就是巨大的成功。
