"Ein Buch zu schreiben ist wie eine Reise in ein unbekanntes Land."

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 past is never dead; it is not even past.

为了克服当代生活的焦虑和抑郁，个人必须在一定程度上独立于社会环境，不再仅仅根据其奖励和惩罚来做出反应。

设定新目标或做新梦想永远不会太老。
