Isn't it true that whatever isn't determined by our genes must be determined by our environment? What else is there? There's Nature and there's Nurture. Is there also some X, some further contributor to what we are? There's Chance. Luck. This extra ingredient is important but doesn't have to come from the quantum bowels of our atoms or from some distant star. It is all around us in the causeless coin-flipping of our noisy world, automatically filling in the gaps of specification left unfixed by our genes, and unfixed by salient causes in our environment.

After Darwin, God's role changes from being the designer of all creatures great and small to being the designer of the laws of nature, from which natural selection can unfold, to being perhaps just the chooser of the laws. By the time God's role has been so diminished, he becomes a bit like a constitutional monarch, presiding ceremonially but not having any more work to do. That's a place for God if it makes people comfortable to keep God as the presider over the universe. I suppose that is satisfying for many.

There is no such thing as philosophy-free science, just science that has been conducted without any consideration of its underlying philosophical assumptions.

Let me lay my cards on the table. If I were to give an award for the single best idea anyone ever had, I'd give it to Darwin, ahead of even Newton or Einstein and everyone else. In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning, and purpose with the realm of space and time, cause and effect, mechanism and physical law. It is not just a wonderful idea. It is a dangerous idea.

I am a philosopher, not a scientist, and we philosophers are better at questions than answers.

If I were to give a prize for the single best idea anybody ever had, I'd give it to Darwin for the idea of natural selection - ahead of Newton, ahead of Einstein - because his idea unites the two most disparate features of our universe: the world of purposeless, meaningless matter and motion, particles jostling on the one side, and the world of meaning and purpose, design on the other.

In the long run I certainly hope information is the cure for fanaticism, but I am afraid information is more the cause than the cure.
