He’s an amazingly disingenuous man. I have no opinion on this episode except noting he was (probably) married at the time, which makes him a scumbag.
I only know him from debates with William Craig over the existence of God. Krauss seemed to be just another scientism sophist who sees himself as too smart to think critically about philosophy because after all he is a scientist and thus doesn't need critical thought because he automatically is its embodiment etc. Guy makes a fool of himself, and its so sad to watch.
