I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

Every kind of peaceful cooperation among men is primarily based on mutual trust and only secondarily on institutions such as courts of justice and police.

The true value of a human being can be found in the degree to which he has attained liberation from the self.

I am not only a pacifist but a militant pacifist. I am willing to fight for peace. Nothing will end war unless the people themselves refuse to go to war.

Peace cannot be kept by force; it can only be achieved by understanding.

Nothing that I can do will change the structure of the universe. But maybe, by raising my voice I can help the greatest of all causes - goodwill among men and peace on earth.
