David B. Hart wonders if the “New Atheism” movement “is only a passing fad—not the cultural watershed its purveyors imagine it to be, but simply one of those occasional and inexplicable marketing vogues that inevitably go the way of pet rocks, disco, prime-time soaps, and The Bridges of Madison County.” He writes that the trend toward godlessness has “proved itself to be so intellectually and morally trivial that it has to be classified as just a form of light entertainment.”
