This is a level of dogmatism that would embarrass any theist. Even the strongest religious believer can imagine the possibility that there is no God. So how can these self- styled champions of reason adopt an approach that is so utterly closed-minded? It is the product of a philosophical commitment many of them have without being aware that they have it. Dawkins and the others seem naively to think that they are apostles of reason who are merely following the evidence. The reason they are deluded about their philosophical commitment is that it is hidden inside the scientific approach itself.
