Sooner or later, man has always had to decide whether he worships his own power or the power of God.

Civilization is a movement and not a condition, a voyage and not a harbor.

As human beings, we are endowed with freedom of choice, and we cannot shuffle off our responsibility upon the shoulders of God or nature. We must shoulder it ourselves. It is our responsibility.

It is a paradoxical but profoundly true and important principle of life that the most likely way to reach a goal is to be aiming not at that goal itself but at some more ambitious goal beyond it.

I do not believe that civilizations have to die because civilization is not an organism. It is a product of wills.
