'Imagine someone holding forth on biology whose only knowledge of the subject is the Book of British Birds, and you have a rough idea of what it feels like to read Richard Dawkins on theology. Card-carrying rationalists like Dawkins, who is the nearest thing to a professional atheist we have had since Bertrand Russell, are in one sense the least well-equipped to understand what they castigate, since they don’t believe there is anything there to be understood, or at least anything worth understanding.
With no claims to faith himself, Eagleton provides some of the best reasoned responses to the emerging New Atheists, IMHO. His book, 'Reason, Faith and Revolution: Reflections on the God debate', came out just before the summer this year.
For anyone who takes Dawkins and his ilk seriously, reading one of Britain's leading literary critics in response, is surely a must read. Ken Myers provides a superb review of Eagleton at the outstanding Mars Hill Audio.
