Manuel DeLanda published his Intensive Science and Virtual Philosophy a little more than ten years ago. The book influenced me greatly at the time, and still does. Here's a slightly revised and expanded version of a review of it I did way back in 2003 in Journal of the British Society for Phenomenology. Here's the hook:
DeLanda provides a doubled difference, a differentiation and differenciation, of Deleuze. While DeLanda certainly provides a straightforward explanation of the process Deleuze calls counter-actualization (moving from the actual to the virtual), he does so not by an interpretation of Deleuze’s full philosophical output, but by a reconstruction of the ontology and epistemology of Difference and Repetition and The Logic of Sense: ‘This line of argumentation ... is, in fact, not Deleuze’s own, although it follows directly from his ontological analysis’ (39). As DeLanda puts it: Deleuze’s world rather than his words. But this folds Deleuze back on himself, giving us a virtualization of Deleuze, moving from the actual productions of Deleuze (his books) to the differentiated structures of his production process (the network of his concepts) in order to produce a new, divergent, differenciation (DeLanda’s book). By virtue of being a book on Deleuze, of course, this product has itself the all-important fold of explaining the structures of all processes (or more precisely, explaining that all processes are structured, and that the structure of the realm of those structures, the virtual, can itself by explicated).
