This is most evident when you consider the poverty of the new atheism’s “error theory”, which is needed to explain why, if atheism is indeed the view evidence and reason demands, so many very bright people are still religious. The usual answers given to this are not good enough. They tend to stress psychological blind-spots and wishful thinking. For instance, Dawkins says “the meme for blind faith secures its own perpetuation by the simple unconscious expedient of discouraging rational inquiry.”

But if very intelligent people are so easily led astray by such things, then shouldn’t the new atheists themselves be more sceptical about the role reason plays in their own belief formation? You cannot, on the one hand, put forward a view that says great intelligence is easily over-ridden by psychological delusions and, on the other, claim that one unique group of people can see clearly what reason demands and free themselves from such grips. Either many religious people are not as irrational as they seem, or atheists are not entitled to assume they are as rational as they seem to themselves.
