Abstract

Descartes is typically interpreted as asserting two related theses: 1) that the will is absolutely free in the sense that no bodily state can compel it or restrain its activity; and 2) that error is always avoidable, no matter what the condition of the body. On the basis of Descartes’s discussions of insanity and dreaming, I argue that both of these interpretive claims are false. In other words, Descartes acknowledged that a diseased or otherwise out of sorts body can compel the will to affirm obscure and confused perceptions. After marshalling textual evidence for this conclusion, I go on to show how Descartes’s acknowledgment of physically induced impaired judgment can be squared with his unqualified assertions of free will, his commitment to the non-deceptiveness of God, and his epistemology.
