Stuart Kauffman is trying to reclaim God for non-believers.
I have a very explicit reason for wanting to use the word "God." It's the most powerful symbol humanity has created. We have been worshiping God or gods at least since the sacred earth mother 10,000 years ago in Europe. In the Abrahamic tradition, our sense of God has evolved. For example, the Israelites, 4,500 years ago, had Yahweh, who was a ferocious warrior, a law-giving God. That's a very different god than the one that Jesus spoke of, a God of love. So our sense of God just in the Abrahamic tradition has evolved.
The question is whether we choose to take our most powerful, invented symbol and use it in a new way to mean the creativity in nature itself. Is it more astonishing to believe in a God who created everything that has come to exist -- planets, galaxies, chemistry, life and consciousness -- in six days? Or is it even more astonishing and awesome to believe what is almost certainly the truth: namely, that all of this came to be all on its own? I think the second.
