I stumbled over this fascinating link at the OUP site, which is apparently a long blog discussion between Peter Heather, who's Fall of the Roman Empire has thrilled those interested in the big-picture reasons for the failure of the West, and Bryan Ward-Perkins, who is not only a friendly colleague but whose book, The Fall of Rome and the End of Civilization is the subject of our upcoming AW Symposion in March.
