Any book by David Berlinski is bound to be fun. He is simply one of the most erudite writers in popular science and mathematics today. Those who particularly like seeing sacred cows treated with a hint of sarcasm and irreverance will enjoy his writing on almost any subject, but this book, attacking the "new atheism" as it does, is especially delightful if for no other reason than for how pompous writers like Richard Dawkins, Daniel Dennett, and Christopher Hitchins are in their approach to this subject.
In brief, Berlinski's argument boils down to three main points: there is nothing in science proper that undermines religion (a point that used to be widely recognized and even extolled by writers like SJ Gould), most of the new atheists badly misunderstand even the most rudimentary arguments of theology and are not logically consistent, and finally that much of science has become rather dogmatic, like a new religion. I think Berlinski does an excellent job addressing all three of these points, the first of which should be more or less self evident. Claims, for example, that one "should" only believe in physical or visible evidence are not, in and of themselves, empirical claims. Indeed, I have friends who resolutely insist that materialism is "all there is" while remaining blissfully unaware of the fact that such a statement could not arise from strictly empirical observation.
