Dawkins' book 'The God Delusion' was a clarion call to the faithless, the waverers, and even firm religious believers, to follow the author into radical atheism not merely as a private conviction but as a public profession. Wouldn't humankind be better off without religion, Dawkins asked. John Cornwell's DARWIN'S ANGEL is not so much a combative repudiation of Dawkins' arguments as a playful conversation with them, posing altermative view-points, exposing lapses in logic and errors of fact, from the vantage point of a friendly Guardian Angel.
