"Dawkins retired as “public understanding” professor in 2008, and he is now in his mid-70s. He basks in the knowledge that he is worshipped by many, but he also seems aware that others – including those who would like to be counted among his intellectual allies – have long believed his cask-strength hectoring would have benefited from a splash of water and a willingness to teach rather than preach. You don’t read Dawkins to be converted from faith to science – though that’s possible; you read him to be fortified in your secular beliefs and to be armed against the Dark Side with handy facts, gestures at powerful theories, and rich stores of satirical rhetoric."
