This last week, with the exception of the night of my birthday, I've been attending a nightly series of stimulating lectures -- one of the benefits of being accorded Visiting Scholar status at European Graduate school this year -- one of which was delivered by Michael Hardt, probably best known outside of progressive and revolutionary academic circles for his collaborative work, Empire (with Antonio Negri).Hardt used the lecture as an opportunity to set out a project he has been working on, but has not yet consolidated into a fully polished form. The central question or problem was that of leadership among non-party, often-marginal, but revolutionary and radically democratic "leaderless movements," Occupy being the one most familiar to us Americans, but comprising a number of different, usually rather transient, and only occasionally effective movements worldwide over the last two decades or so.
