At a moment when some of the theoretical gestures being inspired by old, new, or futuristic political theologies have become ineffective, Paul Kahn’s Political Theology: Four New Chapters on the Concept of Sovereignty is a book of extraordinary significance. Or, perhaps I should say that I think it might be a book of extraordinary significance, inasmuch as it bears a potential to do something which has remained impossible, not only for Carl Schmitt, but also for some important contemporary critics of neo-liberal political economy. I want to reflect specifically about the way this impossibility might become possible, strangely, by way of a new migration of Abraham into the territory of philosophies of freedom and difference.
