Dawkins said in the Guardian recently that he won't debate Craig despite Craig's challenge to meet him this month at Oxford. Dawkins gives several reasons for avoiding Craig, and none of them seem very convincing. And putting them all together doesn't add up to much either.
Here is philosopher Victor Reppert, commenting on what indeed seems like Dawkins avoiding a debate because he's scared (and someone with Dawkin's lack of knowledge of philosophy ought to be):
Dawkins makes the claim that the theist is delusional, by which I take it he means that the case against theism is overwhelming. Yet he doesn't, in any serious way, engage any of the arguments in natural theology, and he seems to imply that it is beneath him to engage leading defenders of belief in the existence of God, and their arguments. I don't care whether he does it in a debate format or some other format, but somewhere, somehow, he needs to show that he knows how the Kalam Cosmological Argument and the Thomistic Cosmological Argument restrict the class of what needs a cause, so that a simplistic "Who made God" can't refute them in any direct way.
Craig is a leading defender of arguments for the existence of God. Regardless of whether some of his statements are morally repugnant, Dawkins needs to come to terms with him and those like him if he is to have any credibility with respect to his delusion charges. Putting his nose in the air with the "Courtier's Reply" does not replace confronting the actual relevant arguments.Read the rest here.
