“If There Is No God” is not the worst thing Prager has ever written. (That honor may go to a two-part op-ed from 2008, titled “When a Woman Isn’t in the Mood,” in which he explains why wives should have sex with their husbands even when they don’t feel like it.) That said, if Prager’s new book were a term paper, his teacher would have a lot to say. She might flag, for instance, that lack of symmetry between his argument and his choice of grisly anecdote. She might object to the tautological reasoning, or to the flagrant cultural animus and Islamophobia. Using terminology from the education world, she might say, politely, that Prager has many “areas of growth” as a student, or that his progress toward grade level is “emerging.”journey-inline-newsletterinline-newsletter
