Theodore Dalrymple, atheist, offers his two cents on all the anti-theism books out there: 

The curious thing about these books is that the authors often appear to think that they are saying something new and brave [...] Yet with the possible exception of [one] they advance no argument that I, the village atheist, could not have made by the age of 14 (Saint Anselm’s ontological argument for God’s existence gave me the greatest difficulty, but I had taken Hume to heart on the weakness of the argument from design).

Of the argument that belief in God can be explained by evolution, Dalrymple offers this terrific analysis: “But of course it is a necessary part of the argument that all possible human beliefs, including belief in evolution, must be explicable in precisely the same way; or else why single out religion for this treatment?”
