历史的终结将是一个非常悲伤的时刻。为纯粹抽象目标而奋斗、愿意冒生命危险的斗争，以及激发勇气、想象力、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.
科学家必须有勇气捍卫自己的思想，即使它们不受欢迎。
饱食终日，宴乐无度，不就是白白地浪费了一天！轻举妄动、胡言乱语、不讲道理、放纵私欲，岂不是就是罪恶的一日！
