As Lewis Hyde (whom I pretty obviously like) puts it, "Irony has only emergency use. Carried over time, it is the voice of the trapped who have come to enjoy their cage." This is because irony, entertaining as it is, serves an almost exclusively negative function. It's critical and destructive, a ground-clearing. Surely this is the way our postmodern fathers saw it. But irony's singularly unuseful when it comes to constructing anything to replace the hypocrisies it debunks. This is why Hyde seems right about persistent irony being tiresome. It is unmeaty. Even gifted ironists work best in sound bites. I find gifted ironists sort of wickedly fun to listen to at parties, but I always walk away feeling like I've had several radical surgical procedures.
