My last vestige of 'hands off religion' respect disappeared in the smoke and choking dust of September 11, 2001, followed by the 'National Day of Prayer,' when prelates and pastors did their tremulous Martin Luther King impersonations and urged people of mutually incompatible faiths to hold hands, united in homage to the very force that caused the problem in the first place.

Bush and bin Laden are really on the same side: the side of faith and violence against the side of reason and discussion. Both have implacable faith that they are right and the other is evil. Each believes that when he dies he is going to heaven. Each believes that if he could kill the other, his path to paradise in the next world would be even swifter. The delusional "next world" is welcome to both of them. This world would be a much better place without either of them.

I am an enthusiastic Darwinian, but I think Darwinism is too big a theory to be confined to the narrow context of the gene.

Most of what we strive for in our modern life uses the apparatus of goal seeking that was originally set up to seek goals in the state of nature.

Cloning may be good and it may be bad. Probably it's a bit of both. The question must not be greeted with reflex hysteria but decided quietly, soberly and on its own merits. We need less emotion and more thought.

Just imagine the banner headlines if a marine biologist were to discover a species of dolphin that wove large, intricately meshed fishing nets, twenty dolphin-lengths in diameter! Yet we take a spider web for granted, as a nuisance in the house rather than as one of the wonders of the world. And think of the furore if Jane Goodall returned from Gombe stream with photographs of wild chimpanzees building their own houses, well roofed and insulated, of painstakingly selected stones neatly bonded and mortared! Yet caddis larvae, who do precisely that, command only passing interest.

The argument from improbability, properly deployed, comes close to proving that God does not exist.
