Humans have always unknowingly affected all Universe by every act and thought they articulate or even consider.

It is a fact today that one in ten thousand of us can make a technological breakthrough capable of supporting all the rest.

However, if we leave the industrial machinery and their energy-distribution networks and leave them also all the people who have routine jobs operating the industrial machinery and distributing its products, and we take away from all the industrial countries all their ideologies and all the politicians and political machine workers, people would keep right on eating.

Everything you've learned in school as "obvious" becomes less and less obvious as you begin to study the universe. For example, there are no solids in the universe. There's not even a suggestion of a solid. There are no absolute continuums. There are no surfaces. There are no straight lines.

Either war is obsolete, or men are.

One can study a caterpillar forever and never be able to predict a butterfly.
