What’s the most serious book you’ve read recently?
Again, I’m too picky with words as my response depends on the definition of “serious.”
I consider the just-reviewed The Challenge a serious book because it deals with serious issues. If the term is meant in a more cerebral context, then it would probably be Society Without God, an examination of Scandinavian countries where religion is not as important as in the U.S., or We Are All Moors, which contends the Moors serve as a metaphor for all minority peoples in the West and a historical antecedent to modern debates over Islam and immigration.
What gunpowder did for war the printing press has done for the mind.
