Hey, wanna see William Lane Craig get schooled by a real physicist?
God & CosmologySean Carroll and William Lane Craig in Dialogue + Q&A
http://www.youtube.com/watch?v=07QUPuZg05IThis is a beautiful kill. Carroll effortlessly dances around Craig and slices him to bloody shreds. Craig's creaky, makeshift, outmoded, amateur cosmic model is like a drugged and lumbering bull to Carroll's matador flair and expertise.
After a long run down of all the flaws of the universe, Carroll says something that really resonated with me... "It's not hard to come up with ipso facto justifications for why God would have done it that way. Why is it not hard?
Because theism is not well defined." Am I alone in thinking that's a brilliant line? It says it all to me.
Theism is so vague, so non-specific that the theist has so much wiggle room to manoeuvre in and never has to commit to specificity. The theist can just keep rapid-firing justifications indefinitely no matter how many objections you raise. The theist can just keep making rationalisations up on the spot. Theism is not an actual cosmological model with predictive utility and explanatory power. It is a blob of Godstuff you can shape into guesses. It's intellectual play-doh. A pliable, shapeable non-explanation that can conveniently be any shape, property or function that the theist needs at any given time, and yet, since it is made out of only empty non-explanation stuff, we still have no actual explanation.
I think people should really give the whole debate a watch. If you already know Craig's routine arguments, it's not entirely necessary to watch his parts because he doesn't bring anything noticeably new (except what I think might be a new concession on his part, in that he is no longer arguing the cosmological argument for the existence of god, but instead the cosmological argument for the existence of premises that have theological significance). I think people with even a casual interest in physics and cosmology will find Carroll's explanations assessable and very interesting. People with sharper knowledge might still find it enjoyable to hear the points articulated so well. It's good stuff.
