Somewhere at the heart of “I Still Haven’t Found What I’m Looking For”—an Edge song title—is John Bunyan’s idea of the pilgrim’s progress. Or in my case, the lack of it. If I mostly find religiosity annoying, right up at the top of the annoying is the pigheaded certainty of the devout without the doubt. Not just no room for doubt in the God they follow, but no doubt in their ability to decipher the holy tracts. No doubt their version of events is the right one.
