A revisionary reading of Descartes's epistemology has emerged in the literature. Some commentators have argued that Descartes subscribes to passionate epistemology, which claims that epistemic progress in the Meditations requires contributions from the meditator's passions. This paper argues that the passions cannot perform any epistemic work in the Meditations. As such, the meditator's passions do not require us to revise our canonical understanding of the Meditations as an exercise of pure thought. Furthermore, we need not abandon the standard claim that ethical practice emerges in the tree of philosophy only after metaphysics and epistemology have been established.
