真相很少是纯粹的，也从来不是简单的。

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.

People tend to value things more highly when they own them.

真理永远不会伤害一个正义的事业。
