永遠不要低估人類精神的力量。它可以克服最不可能的困難。
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.
A true leader must be able to listen to the voices of the people.
The method of psychology must be as exact as that of the physical sciences.
I think that we communicate only too well, in our silence, in what is unsaid.
