I just would like to say that over more than a quarter-century as a scientist and a believer, I find absolutely nothing in conflict between agreeing with Richard [Dawkins] in practically all of his conclusions about the natural world, and also saying that I am still able to accept and embrace the possibility that there are answers that science isn't able to provide about the natural world - the questions about why instead of the questions about how.
