Abstract

In recent years, a number of commentators have expressed dissatisfaction with Spinoza’s account of practical reason. In this paper, I defend his account against the most prominent objections, showing that the dictates of reason play an important role in guiding thought and action. However, against the standard interpretation, I propose that we view these rules not as exceptionless, instrumental prescriptions—hypothetical imperatives with necessary antecedents, as Curley memorable put it—but rather as adaptable guideposts that aid us in the complex, dynamic process of acquiring a habit of virtue. The dictates of reason are best understood as defeasible policies that help to orient one in the ars vivendi.
