The New Yorker has a powerful profile of David Foster Wallace, which includes this passage:
“It seems important to find ways of reminding ourselves that most ‘familiarity’ is meditated and delusive,” he said in a long 1991 interview with Larry McCaffery, an English professor at San Diego State. The default for Wallace would have been irony—the prevailing tone of his generation. But, as Wallace saw it, irony could critique but it couldn’t nourish or redeem. He told McCaffery, “Look, man, we’d probably most of us agree that these are dark times, and stupid ones, but do we need fiction that does nothing but dramatize how dark and stupid everything is?”
Clearly Wallace had other aims for his art than simply recording the more vacuous currents of the time he lived in. Something we poets might want to ponder.
