The re-drafting of the Persistence of the Negative is currently taking up most of my time, and I'm very grateful to all the readers/commentators who have at least prevented some of the more major errors. Certainly I'm a lot happier now with the Derrida chapter (more streamlined), the Latour chapter (nastier), and the Negri chapter (fairer).
I just got some overall comments from John Roberts, author of this excellent book, and they form their own analysis of the state of theory, this is an extract:
"It [Persistence of the Negative] renders the theory and philosophy as moments within a collective 'research programme', despite all the professional and political animosities of the given writers (an approach that Badiou pursues himself in his recent essay on post-French philosophy in NLR). Your decision then to connect this body of writing through the concept of 'affirmationism' is vivid, insofar as it becomes clearer forty years after May 68 and 10 years after this 68 philosophical legacy begins to fall into decline, that in these authors’ shared desire to accelerate away from a certain crisis in the form and affective life of revolutionary politics, the celebration of the actual becomes a chronic liability. I myself see this as a result, firstly of a misreading and then abandonment of Hegel (and Marx's fundamental indebtedness to Hegel), in the widespread turn within this tradition to discontinuism, conjuncturalism, alinearity, and anti-causality, which finds its perfected form, of course, in Logics of Worlds, where causality is exchanged for a kind of telescopic historical abridgement. The relations between affirmation, negation and historical development, therefore, have been sundered in this tradition, which, in a sense is where your book enters the fray. But as I said, in our discussion, the absence of a discussion of Hegel renders the critique of a post-historical affirmationism (certainly in Badiou) without a philosophical anchor."
