There's nothing nonsensical about saying that what would evolve if Darwinian selection has its head is something that you don't want to happen. And I could easily imagine trying to go against Darwinism.

Steve Grand is the creator of what I think is the nearest approach to artificial life so far, and his first book, Creation: Life and How to Make It, is as interesting as you would expect. But he illuminates more than just the properties of life: his originality extends to matter itself and the very nature of reality. Not since David Deutsch's The Fabric of Reality have I encountered such a compelling invitation to think everything out afresh, from the bottom up.

There is great variation in brain power all the way from Einstien on one hand to Sarah Palin on the other.

Textbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible. But today I want to present it as something different again, and even more intriguing. The DNA in you is a coded description of ancient worlds in which your ancestors lived. DNA is the wisdom out of the old days, and I mean very old days indeed.

Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium.

I guess there are some rights of parents with what they choose their children to learn, but I'm biased in favor of freeing children to learn and not letting parents be too doctrinaire in indoctrinating their children.

I have no explanation for complex biological design. All I know is that God isn't a good explanation, so we must wait and hope that somebody comes up with a better one.
