It seems to me an utterly futile task to prescribe rules and limitations for the conduct of war. War is not a game; hence one cannot wage war by rules as one would in playing games. Our fight must be against war itself. The masses of people can most effectively fight the institution of war by establishing an organization for the absolute refusal of military service.

I never teach my pupils, I only attempt to provide the conditions in which they can learn.

External conditions can, to a certain extent, reduce, but never cancel individual repsonsibility.

The world is a dangerous place to live; not because of the people who are evil, but because of the people who don't do anything about it.

In two weeks the sheeplike masses of any country can be worked up by the newspapers into such a state of excited fury that men are prepared to put on uniforms and kill and be killed, for the sake of the sordid ends of a few interested parties. Compulsory military service seems to me the most disgraceful symptom of that deficiency in personal dignity from which civilized mankind is suffering today.

Give back to the world at least what you've received.

Imagination is the most powerful force in the universe.
