[Update added below. Further update: here's the video.] I'm participating this afternoon in an intriguing event here at Caltech:
The Great Debate: "Has Science Refuted Religion?"
Affirming the proposition will be Skeptics Society president Michael Shermer and myself, while negating it will be conservative author Dinesh D'Souza and MIT nuclear engineer Ian Hutchinson. We'll go back and forth for about two hours, after which Sam Harris will give a talk about his most recent book, Free Will.
Festivities begin at 2pm Pacific time (5pm Eastern). I hadn't previously mentioned the debate here on the blog, because tickets sold out pretty quickly, and it didn't seem right to taunt people by mentioning an event they couldn't come see. But the Skeptics folks have been working hard to set up live-streaming video of the event, and it looks like they've succeeded! So you should be able to watch all the fun live ...
