Life clearly does more than adapt to the Earth. It changes the Earth to its own purposes. Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.

I'm all in favor of looking deeply into as much as we possibly can. I'm not afraid of knowledge... With all new technology, weapons inevitably emerge... Evil comes out of the human heart. It doesn't come out of nature.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
