I've been watching some of Sam Harris' talks on various television programs and conferences and find him to be a very eloquent and capable spokesman for atheism. His points are so clear and he backs them up with real life examples so well. I haven't read his books yet, but I plan to soon. I am greatly looking forward to deeper elaborations on all of his points. For a quick summary of his thinking check out this video from Idea City 2005. Make sure to play it to the end. The comment the presenter makes was exactly what I was thinking in my head.
