From early in his philosophical career, Spinoza took a central part of his project to involve identifying the nature and scope of human power. For, he argues, “The better the mind understands its own powers, the more easily it can direct itself and propose rules to itself” (TIE[40]). Thus, the practical goals of living well, and of building a stable, well-functioning social order, are both intimately connected to the metaphysics of power. This entry provides an overview of Spinoza’s account of power, both in his metaphysics and in his politics.
