历史的终结将是一个非常悲伤的时刻。为了纯粹的抽象目标而愿意冒生命危险的斗争，全球意识形态斗争所唤起的勇气、想象力、理想主义，将被经济计算、无休止的技术问题解决、环境关注和复杂消费者需求的满足所取代。
The end of history will be a very sad time.

The struggle itself towards the heights is enough to fill a man's heart. One must imagine Sisyphus happy.
Technology is only as useful as the people who use it.
普通城市是从中心的囚禁中解放出来的城市，从身份的束缚中解放出来。
