I have never before seen Krauss debate, but the physicist opened up explaining he did not particularly like them. I was shocked to discover that Krauss’ entire opening statement revolved around criticizing Craig’s well-known arguments as “God-of-the-gaps.” He also mentioned that quantum mechanics demonstrates that physics does not conform to the laws of logic (thus, in my view, demonstrating a fundamental equivocal misunderstanding of the term “logic.” It does not mean, as Krauss here seems to suggest, “common sense” or “what we would expect.” This is the most charitable view as the only other sense he could mean is that it is reasonable to assume reason does not apply to physics, while also giving us a reason, which is self-contradictory.). He also suggested God cannot be the grounds of objective morality since God can’t will evil things to be good.
[…]In Craig’s second rebuttal he again focused the debate topic. Craig does this to show both what he has argued and to show that the rebuttal was not at all relevant to the topic at hand. I wished he had discussed more cosmology and why inflationary models require an absolute beginning, but he at least mentioned these rebuttals. He completely tore apart the Humean argument against miracles by pointing out that he did not have the probability calculus back in that time. Craig seemed perfectly comfortable by this point and not at all rushed; however he had fewer points to argue against as Krauss was defaulting to “desire” as a motivator over scientific evidence.
By the time of Krauss’ second rebuttal, he was struggling for words. He seemed to have run out of things relevant to say. He did eventually get going, but made such contradictory statements as “there is no purpose in the universe.” As Ryan Hedrich said to me during the debate, “There’s no meaning, no purpose, and yet there he is, arguing away for God only knows what reason (literally).”
And he even reviews the Q&A. This is a really good review.
