I said "first book" because Matt and I are planning on co-authoring and completing a book entitled "A Hermeneutics of Emancipation: A Critical Introduction to Miguel Abensour" within the next few years. I also hear that he's got some other project on the go as well.
We'll be swapping our recent books during reading week, so I hope to be able to say something about Philosophy, Sophistry, Antiphilosophy either on the blog or in actual review form sometime soon. From what I know about Matt's work, his argumentation style is both merciless and sympathetic. I'm not quite sure how he does it, but it makes for good reading.
