This comes from Richard Dawkins's blog.
This is part one of a two-hour discussion between four of the great rational & scientific thinkers of our age: Dawkins himself, philosopher Daniel Dennett, and authors Sam Harris and Christopher Hitchens. I've read a bunch of stuff from each of them, and though I don't know Dennett particularly well, the other three would be on the top of my list of recommended authors. Richard Dawkins's work popularizing biology is of inestimable worth, and Hitchens and Harris have both done fantastic work debunking religious hooey.
I think one would be hard-pressed to ever find four finer minds assembled in one place for an informal chat. This is like getting invited to sit at the dinner table with the crowd that would never have me. So get yourself something to drink and a comfy chair and settle in.
