David Foster Wallace (1962-2008) said, “Irony, entertaining as it is, serves an almost exclusively negative function,” he once wrote. “It’s critical and destructive, a ground-clearing. Surely this is the way our postmodern fathers saw it. But irony is singularly unuseful when it comes to constructing anything to replace the hypocrisies it debunks.” This quoted in The Independent, which ran a final tribute today.
