My pacifism is not based on any intellectual theory but on a deep antipathy to every form of cruelty and hatred.

If there is any religion that could respond to the needs of modern science, it would be Buddhism.

Nothing happens until something moves. When something vibrates, the electrons of the entire universe resonate with it. Everything is connected.

I hate all the loathsome nonsense that goes with patriotism.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Curiosity is a delicate little plant that, aside from stimulation, stands mainly in need of freedom.

I believe serious progress (in the abolition of war) can be achieved only when men become organized on an international scale and refuse, as a body, to enter military or war service.
