That Massumi lecture is part of a series, including pieces by Bauman and Chomsky, which is itself part of a wider project run by Brad Evans at University of Leeds on ‘Histories of Violence’. The project has a website here, though it says it won’t be launched until 11th September. But looks like lots of interesting stuff to come – including video lectures by J. Peter Burgess, Simon Critchley, Michael Dillon, Brad Evans, Steven Graham, Michael Hardt, Ted Honderich, Mary Kaldor, Todd May, Avital Ronnell, Ilan Safit, Saskia Sassen, Cynthia Weber, and Samuel Weber.
