Abstract
On Descartes’s account, the will is the central player in judgment, a role that this chapter aims to explain. The first section situates the will in Descartes’s broader ontology of mind. The second section characterizes the will’s contributions to judgment. The third section addresses the will’s voluntary control over judgment. The fourth section considers whether, on Descartes’s account, our epistemic responsibility in judgment is best understood as a form of compatibilism or incompatibilism.
