Smiddy I have read it and I think it's very good once you get past the religion bashing at the beginning where I do think Dawkins goes on a bit and is rather offensive to religious people. The thing is if he is trying to draw people to evolution then why insult them? Interested to know what you think about the last chapter when he mentions miracles. I found his comments about miracles a little odd.
You might also enjoy The Science Delusion by Rupert Sheldrake. He is a biologist and has worked at Cambridge and Harvard. He thinks scientists have become rather dogmatic in their assertions. Haven't finished it myself yet and I don't agree with everything he says but it is quite an eye - opener as to some of the motivating factors affecting scientists - peer pressure and getting funding for research among them.
