From Larry McCaffery’s “Conversation with David Foster Wallace” (Dalkey Archive Press at the University of Illinois: Summer 1993):
Irony and cynicism were just what the U.S. hypocrisy of the fifties and sixties called for. That’s what made the early postmodernists great artists. The great thing about irony is that it splits things apart, gets up above them so we can see the flaws and hypocrisies and duplicates. The virtuous always triumph? Ward Cleaver is the prototypical fifties father? “Sure.” Sarcasm, parody, absurdism and irony are great ways to strip off stuff’s mask and show the unpleasant reality behind it. The problem is that once the rules of art are debunked, and once the unpleasant realities the irony diagnoses are revealed and diagnosed, “then” what do we do? Irony’s useful for debunking illusions, but most of the illusion-debunking in the U.S. has now been done and redone. Once everybody knows that equality of opportunity is bunk and Mike Brady’s bunk and Just Say No is bunk, now what do we do? All we seem to want to do is keep ridiculing the stuff. Postmodern irony and cynicism’s become an end in itself, a measure of hip sophistication and literary savvy. Few artists dare to try to talk about ways of working toward redeeming what’s wrong, because they’ll look sentimental and naive to all the weary ironists. Irony’s gone from liberating to enslaving. There’s some great essay somewhere that has a line about irony being the song of the prisoner who’s come to love his cage.

The problem is that, however misprised it’s been, what’s been passed down from the postmodern heyday is sarcasm, cynicism, a manic ennui, suspicion of all authority, suspicion of all constraints on conduct, and a terrible penchant for ironic diagnosis of unpleasantness instead of an ambition not just to diagnose and ridicule but to redeem. You’ve got to understand that this stuff has permeated the culture. It’s become our language; we’re so in it we don’t even see that it’s one perspective, one among many possible ways of seeing. Postmodern irony’s become our environment.
