饥饿和贫困是世界上许多动荡和苦难的根本原因。
Hunger and poverty are the root causes of much of the world's unrest and misery.
只要是利益他人的事情，就要坚持做下去；只要是不利于别人的事情，就要马上停止不做。
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.
"In science, the credit goes to the man who convinces the world, not to the man to whom the idea first occurs."
