Sue Blackmore debates Alister McGrath

Over on richarddawkins.net there is an mp3 of a debate between Sue Blackmore and Alister McGrath on the topic 'belief in God is a dangerous delusion'. What i found particularly wacky was Blackmore's use of 'meme theory'. I find the metaphor of memetics fascinating, and really love it as a way of looking at ideas. But the way Blackmore explains it, humans have no agency of their own or critical faculties when it comes to selecting the beliefs they hold. Religious ideas are seen as trying to take over our brains, so if one finds them compelling that is not evidence that there is any truth to them, but that they have 'evolved' to be more convincing.
