可持续性不是一种趋势，而是我们对后代的责任。
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.
The world is full of beauty, but it is also full of pain and suffering.
The future belongs to those who fight for it.
真正爱国者的职责是保护他的国家免受其政府的侵害。
