Deleuze Among the Scotists: Difference-In-Itself and Ultima Differentia

This article presents an interpretation of Deleuze’s concept of difference-in-itself. I argue that this is best understood as an ad(o/a)ption of Duns Scotus’s concept of ultimate difference. After suggesting that the influence of Scotus on Deleuze extends beyond their shared commitment to the univocity of being, I turn to briefly review Deleuze’s notion of absolute difference. I proceed from there to explain Scotus’s accounts of univocity and ultimate difference, throughout noting the many stark parallels with Deleuze. On the basis of this Scotistic reading of Deleuzian difference, I then show how Deleuze’s synthesis of univocal being and difference-in-itself can be uniquely situated within the fourteenth-century Scotistic disputations on the predicability of univocal being to ultimate difference. I conclude with some suggestions on possible further connections between Deleuze and medieval metaphysics which are opened up through this association of Deleuze with Scotus and the Scotistic tradition.
