Strength.

Rembrandt, Scholar Reading, 1631

When the farthest corner of the globe has been conquered technologically and can be exploited economically; when any incident you like, at any time you like, becomes accessible as fast as you like; when you can simultaneously “experience” an assassination attempt against a king in France and a symphony concert in Tokyo; when time is nothing but speed, instantaneity, and simultaneity, and time as history has vanished from all Dasein of all peoples; when a boxer counts as the great man of a people; when the tallies of millions at mass meetings are a triumph; then, yes then, there still looms like a specter over all this uproar the question: what for? — where to? — and what then? 

The spiritual decline of the earth has progressed so far that peoples are in danger of losing their last spiritual strength, the strength that makes it possible even to see the decline and to appraise it as such. This simple observation has nothing to do with cultural pessimism — nor with any optimism either, of course; for the darkening of the world, the flight of the gods, the destruction of the earth, the reduction of human beings to a mass, the hatred and mistrust of everything creative and free has already reached such proportions throughout the whole earth that such childish categories as pessimism and optimism have long become laughable.
