Most great writers are also great talkers, but writing begins where talking ends: in silence. Norman Mailer is one of literature’s great talkers, and his voice—his speaking voice—is crucial to his work. As a founding partner of a new upstart Greenwich Village weekly in the mid-nineteen-fifties, he even came up with its title: the Village Voice. Perhaps no writer of his time endured such keen conflict between his personal voice and his literary voice, and that conflict is at the center of “Selected Letters of Norman Mailer,” edited by J. Michael Lennon.
