What can I say about Norman Mailer, who recently passed away: great writer, colorful personality, and an arrogant prick. He made modern literature macho. Mailer behaved more like a Hollywood celebrity--whose hijinx is well-documented--than a well-respected author. Mailer did not demur from such characterizations. In fact, he invited it, upto to his last days.
Christopher Hitchens says it best, in my opinion. Roger Kimball, editor at New Criterion, offers a dissenting view.
