Dawkins admits he could be wrong on the god question? I've never seen that; unless of course it's insincere and be using to point out just how ridiculous the religious are "see, I believe in science, I'm open to having my mind changed!" No he's not. He is absolutely and totally invested in his brand of Atheism. If a supernatural being came down and smote him he would be explaining it away as a meteorological phenomenon or the like.

I don't think I'm claiming that atheists have to be able to claim "I cannot be wrong on this"; my issue with atheism is that it puts the lack of existence of god as a statement of fact, which is ridiculous, you can't prove a negative, therefore it's outside the realm of possible knowledge, therefore a ridiculous question. Feel free to say "on the weight of evidence I believe there is no god", but that's a statement of belief, not knowledge. When atheists claim to have knowledge of the lack of existence of a god then they are devaluing the concept of knowledge.

I really have to stress that I am making a point of epistemology, not ontology or metaphysics. What is important here *isn't* whether or not god exists, but "what is knowledge?"
