All appearances to the contrary, the only watchmaker in nature is the blind forces of physics . . . A true watchmaker has foresight: he designs his cogs and springs and plans their interconnections, with a future purpose in his mind's eye. Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no vision, no foresight, no sight at all. If if can be said to play the role of watchmaker in nature, it is the blind watchmaker.
From "the blind watchmaker" by Richard Dawkins.So the organised complexity of our bodies was not designed, it was purely the blind forces of physics operating. I'm not in a position to say whether this is possible but I'll trust those evolutionary biologists like Dawkins here who claim this.
But when Dawkins says that the complexity of living creatures is achieved in an entirely different way to human inventions such as a watch, he concedes there is design in nature -- namely human artifacts such as watches. Darwinian evolution surely entails there is no design whatsoever. So human beings cannot be part of nature, or alternatively the mainstream evolution position is falsified?
I confess though I haven't read Dawkins' book. Or any of his books although I've read articles by him. But he just bangs on about God in those articles and doesn't address the shortcomings of naturalism/materialism.
