Professor of Historical Theology at Oxford University and former senior molecular biophysicist Alister McGrath gave a talk earlier in 2007 called "The Dawkins Delusion", which is also the title of his recent book - one I will be reviewing at some point. The lecture is available for download here (sound file), and is copyright St Ebbe’s Church, Oxford (copying talks is prohibited).
As a former atheist, McGrath is respectful yet critical of the movement. In recent years, he has been especially interested in the emergence of what claims to be "scientific atheism", and has researched the distinctive approach to atheist apologetics found in the writings of the Oxford zoologist and scientific popularizer Richard Dawkins. A video of an extended discussion between Dawkins and McGrath on science and faith now available, courtesy of Dawkins' website, here (mov. file)
At present, McGrath is researching the iconic role played by Charles Darwin in atheist apologetics, and the appeal to the controversial concept of the "meme" in recent atheist accounts of the origins of belief in God.
I have a number of differences with McGrath at certain points, but he has made some thoughtful and important criticisms of Dawkins on religion in his recent two books.
