Rick Warren vs. Daniel Dennett

I'm a big fan of the TED talks there are some amazing talks on here on a variety of subjects and if you haven't taken the time to view some of them, do yourself a favor and indulge. I found these two videos particularly neat. Rick Warren is of course the evangelist and preacher who wrote the monumentally famous The Purpose Driven Life here's his full bio on TED. He makes some interesting points in the talk and I can see why he's a compelling speaker and an inspiration to many modern Christians.

But Daniel Dennett, an outspoken atheist and humanist, seemed to find fault in what Pastor Warren had to say and challenged him in his response talk. I find it very interesting, and tend to agree with Dennett. I wonder what you think?
