The world is so unhappy because it is ignorant of the true self. Man's real nature is happiness. Happiness is inborn in the true self. Man's search for happiness is an unconscious search for his true self.
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.
