历史的终结将是一个非常悲伤的时刻。为了纯粹抽象的目标而愿意冒生命危险的认可斗争，呼唤出大胆、勇气、想象力和理想主义的全球意识形态斗争，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 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.
