Every thought is an afterthought.

I'm more than ever of the opinion that a decent human existence is possible today only on the fringes of society, where one then runs the risk of starving or being stoned to death. In these circumstances, a sense of humor is a great help.

Thinking does not lead to truth; truth is the beginning of thought.

Revolutions are the only political events which confront us directly and inevitably with the problem of beginning.

If we don't know our own history, we are deemed to live 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.

Only the hypocrite is really rotten to the core.
