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.

Imagination encircles the world.

My sailing system set sail, make it fast, no thoughts of energy or velocity, loll back, let boat drift.

Make everything as simple as possible, but not simpler. A man should look for what is, and not for what he thinks should be. We cannot solve our problems with the same thinking we used when we created them. A question that sometimes drives me hazy: am I or are the others crazy? Any intelligent fool can make things bigger and more complex... It takes a touch of genius - and a lot of courage to move in the opposite direction. All religions, arts and sciences are branches of the same tree. It's not that I'm so smart, it's just that I stay with problems longer.

God does not play dice.

Democracy, taken in its narrower, purely political, sense, suffers from the fact that those in economic and political power possess the means for molding public opinion to serve their own class interests. The democratic form of government in itself does not automatically solve problems; it offers, however, a useful framework for their solution. Everything depends ultimately on the political and moral qualities of the citizenry.

After a certain high level of technical skill is achieved science and art tend to coalesce in aesthetics, plasticity, and form. The greatest scientists are artists as well.
