Was Spinoza a Deleuzian? Rethinking the Politics of Emotions and Affects

A salient tradition in contemporary affect theory heavily relies on distinguishing between emotions and affects. The former refers to structured categories of socially coded affective states, while the latter denotes the pre-social libidinal flow underlying emotions. This distinction is commonly attributed to Spinoza and is thought to have been further developed by Deleuze. In this article, I argue that this overall historical picture is misleading and inaccurate. Deleuze radically transforms Spinoza's theory of affect for the ends of his own ethical-political philosophy. Moreover, I argue that Deleuzian and similar conceptualizations of affect fail to fulfill their political and ethical promises due to two critical problems. In the last section, I show that a unified notion of emotion inspired by Spinoza, which does not create a sharp rift between emotions and affect, can perform the same explanatory function intended by the emotion-affect distinction while allowing us to circumvent these problems.
