Democracy is good. I say this because other systems are worse.

Loyal and efficient work in a great cause, even though it may not be immediately recognized, ultimately bears fruit.

Every great revolution, whether it is right or not, we really know has any vital, urgent need to basis. It comes not just from itself.

I have always thought that the best way to find out what is right and what is not right, what should be done and what should not be done, is not to give a sermon, but to talk and discuss, and out of discussion sometimes a little bit of truth comes out.

The only alternative to coexistence is codestruction.

Obviously, the highest type of efficiency is that which can utilize existing material to the best advantage.

The future belongs to science and those who make friends with science.
