For those who are interested, now Richard Dawkins has a YouTube account, he has been uploading many of his videos, which make for interesting watching for those of us who glady don't believe, and for those who do.
He has now included "The Four Horsemen" in High Definition, which involved a two hour discussion between Dawkins, Hitchens, Harris and Dennett. I thought I would share the link with you now. (This is only the first hour, the second one to follow shortly). Hope this is useful for everyone.
