"Fifty years ago, philosophers like Bertrand Russell felt that the religious worldview would fade as science and reason emerged. Why hasn't it?

That trend toward enlightenment has indeed continued in Europe and Britain. It just has not continued in the U.S., and not in the Islamic world. We're seeing a rather unholy alliance between the burgeoning theocracy in the U.S. and its allies, the theocrats in the Islamic world. They are fighting the same battle: Christian on one side, Muslim on the other. The very large numbers of people in the United States and in Europe who don't subscribe to that worldview are caught in the middle.

Actually, holy alliance would be a better phrase. 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."

The idea that evolution could be "random" seems to frighten people. Is it random?

This is a spectacular misunderstanding. If it was random, then of course it couldn't possibly have given rise to the fantastically complicated and elegant forms that we see. Natural selection is the important force that drives evolution. Natural selection is about as non-random a force as you could possibly imagine. It can't work unless there is some sort of variation upon which to work. And the source of variation is mutation. Mutation is random only in the sense that it is not directed specifically toward improvement. It is natural selection that directs evolution toward improvement. Mutation is random in that it's not directed toward improvement.

The idea that evolution itself is a random process is a most extraordinary travesty. I wonder if it's deliberately put about maliciously or whether these people honestly believe such a preposterous absurdity. Of course evolution isn't random. It is driven by natural selection, which is a highly non-random force.
