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.

Innovation requires courage and the willingness to break conventions.

The sun himself is weak when he first rises, and gathers strength and courage as the day gets on.

一本书是作者与读者之间跨越时空的对话。
