A curious thing happens when two atheists realize that man worships himself and that knowledge without God tends to lead us into Cartesian absurdity. One writes a book explaining how materialism is little more than self-assured preening by scientists who can’t grasp their own ideas, and gets praised, in a lefty rag, by perhaps the foremost Christian philosopher of our day. The other decides “progress” is a delusion caused by our evolution into narcissistic animals, and the first guy tears into him for it.

The inestimable Peter Leithart arbitrates.
