According to William Alston, we lack voluntary control over our propositional attitudes because we cannot believe intentionally, and we cannot believe intentionally because our will is not causally connected to belief formation. Against Alston, I argue that we can believe intentionally because our will is causally connected to belief formation. My defense of this claim is based on examples in which agents have reasons for and against believing p, deliberate on what attitude to take towards p, and subsequently acquire an attitude A towards p because they have decided to take attitude A. From the possibility of intentional belief, two conclusions follow. First, the kind of control we have over our propositional attitudes is direct; it is possible for us to believe at will. Second, the question of whether what we believe is under our control ultimately depends on whether our will itself is under our control. It is, therefore, a question of the metaphysics of free will.
