Deleuze's monograph on Foucault is often construed as a ‘metaphysical fiction’ (Frédéric Gros), which would attribute to Foucault a metaphysics of Deleuze's own issue. Notably, Paul Patton has argued that Deleuze thereby deeply mischaracterises Foucault's concepts of actuality, history, power and philosophy itself. Against this view, I argue that Deleuze's interpretation in Foucault clarifies the virtual force ontology that the two thinkers effectively developed in common. This ontological framework not only resolves Patton's specific objections; it also outlines a philosophy of (...) the event demonstrating the conceptual consistency between Foucault and Deleuze on fundamental questions of philosophical critique and political agency.
