Violence can destroy power; it is utterly incapable of creating it.

The chief reason warfare is still with us is neither a secret death-wish of the human species, nor an irrepressible instinct of aggression, nor, finally and more plausibly, the serious economic and social dangers inherent in disarmament, but the simple fact that no substitute for this final arbiter in international affairs has yet appeared on the political scene.

It interrupts any doing, any ordinary activities, no matter what they happen to be. All thinking demands a stop-and-think.

Political questions are far too serious to be left to the politicians.

Nobody is the author or producer of his own life story ... somebody began it and is its subject in the twofold sense, namely, its actor and sufferer ... but nobody is the author.

This inability to think created the possibility for many ordinary men to commit evil deeds on a gigantic scale, the like of which had never been seen before. The manifestation of the wind of thought is not knowledge but the ability to tell right from wrong, beautiful from ugly. And I hope that thinking gives people the strength to prevent catastrophes in these rare moments when the chips are down.

... we have almost succeeded in leveling all human activities to the common denominator of securing the necessities of life and providing for their bundance. Whatever we do, we are supposed to do for the sake of "making a living;" such is the verdict of society, and the number of people, especially in the professions who might challenge it, has decreased rapidly. The only exception society is willing to grant is to the artist, who, strictly speaking, is the only "worker" left in a laboring society.
