Dimitris Vardoulakis' Spinoza, the Epicurean: Authority and Utility in Materialism puts forward the bold thesis that there is a dialectic of authority and utility in Spinoza. That obedience is situated between authority, between the "Potestas" of kings and God, and utility, the potentia of intellect and bodies. It is from this perspective that Vardoulakis presents a reading of Spinoza's Tractatus Theologico-Politicus. Despite the title of the book, which suggests a more modest exegetical undertaking, the stakes of this are less a matter of tracing the epicurean dimensions of Spinoza's thought, although that is done, than using those threads to expand the stakes of Spinoza's political thought. Vardoulakis' book takes on not only other readers of Spinoza, Negri, Deleuze, Althusser, Balibar, and Sharp, but also the central question of Spinoza's thought, why do people fight for their servitude as if it was salvation?
