I finished Richard Dawkins new book The God Delusion last week. I’m not sure many people will be surprised to learn that I agree with the points and argument presented in the book almost completely. There are a few minor points that I don’t agree totally with. One being the invocation of the The Anthropic Principle, in the guise of a planetary version, in relation to the discussion of the origins of life on Earth. I don’t think it’s required. Obviously as the Earth contains life then, from a weak anthropic standpoint, the conditions we find on Earth must be favourable. But I don’t think we need to invoke a planetary version of the Anthropic Principle for this. Dawkins argues that the formation of the original life was probably a very improbable event but given the number of stars and planets in our galaxy, indeed the Universe, then if on even a very, very small number of these planets such an improbable event occurred then there would be many planets where life had started. We just happen to be living on one of them.
I’m comfortable with the Anthropic Principle (the weak form) when used in relation to the Universe. If the Universe didn’t have laws that allowed creation of stars, planets etc. then we simply wouldn’t be here to ponder and discuss it. But I don’t think we need to use it to explain the origins of life. The laws of chemistry show that molecules self assemble. So in any environment that has the correct chemicals then I think molecules will form and some of those molecules will be able to catalyse the formation of copies of themselves. Some will be better at this than others and therefore will be subject to Darwinian natural selection. Thus in any system where molecules can form and compete for resources we have the first step up the far side of Dawkins’ Mount Improbable.
The God Delusion is a wonderful book. Everyone should read it. Seems many are as it’s top of many best seller lists and has had several reprints to take the number in print, in just 2 weeks, to 100,000+. I promised several people a review of the book here. I plan to read it again and record references in Endnote for future use in discussions with creationists and ID proponents. I’ll post more comprehensive thoughts after that. But the bottom line is get a copy and read it.
