As a recent book argues, God is indeed back. And one of the authors is an atheist! If I had the time, I think I'd enjoy reading this. Mark Greene seems to like it, and provides a neat summary here.
Check out the negative 'reviews' on amazon.com, though - one hasn't read it, one doesn't review the book but simply splurges briefly (mercifully) against religion, and one directs us to this further interesting site, worldvaluessurvey.org...
