You might like to check out the 49th edition of the Humanist Symposium, which has been posted at The Purloined Letter, with an Edgar Allan Poe theme. One of the items there is my recent discussion of Robert Wright's The Evolution of God, but there's much other material that (also!) looks interesting.
Go read and check it out. These blog carnivals/symposia need readers, so if you like what you see spread the word.
