D.T. Max, staff writer at the New Yorker, looks at David Foster Wallace and irony, with an eye especially on his 1990's attacks on David Letterman and the novelist Mark Leyner, both in publications and in private correspondence. When did David Foster Wallace become obsessed with irony and why? What made him so sure it was corrosive to civil culture or initiative? Or was the unease he felt in its presence really more the product of his own personal history? Co-hosted with Literature at MIT.
