While interviewing James Comey tonight, Stephen Colbert happened to mention Pascal's Wager. I hadn't heard the term before, so I looked it up. I've heard the argument before, of course--basically that you should believe in the Christian god because if He exists your true belief will earn you eternal life, and if he doesn't exist your false belief won't cost you much. It's one of those fun arguments that on first glance can be quite challenging, but upon reflection has many holes. Have you considered Pascal's wager? If so, how have you answered it?
