Modal Essence and Power in Deleuze's Spinoza

In this article I critically assess Deleuze's interpretation of Spinoza's metaphysics of modes. I argue that the conception of modal essence that Deleuze attributes to Spinoza is untenable in terms of Spinoza's metaphysics. I further show that the idea that modal essences are eternally static degrees of power is incompatible with Spinoza's ethics, wherein modes strive to increase their power by means of positive interactions with others. I suggest that Deleuze's interpretation of this crucial aspect of Spinozism runs the risk of reinstating Platonic idealist and moralistic themes, of the kind that both Spinoza and Deleuze are committed to overcoming.
