快乐的唯一方式是忠于自己。
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.
可持续发展不仅是一种趋势,更是我们对未来的责任。
要理解意识,就要研究它在生存中的作用。
