Abstract

Ockham appeared to maintain that God necessarily knows all true propositions, including future contingent propositions, despite the fact that such propositions have determinate truth values. While some commentators believe that Ockham’s attempt to reconcile divine omniscience with the contingency of true future propositions amounts to little more than a simple-minded assertion of Ockham’s Christian faith, I argue that Ockham’s position is more sophisticated than this and rests on attributing to God a dual knowledge property: God not only knows every true proposition, but knows its modal properties as well. Future contingent propositions are determinately true when actualized, not timelessly, and God’s knowledge of their truth values is knowledge of when the truth value of a proposition is actually determined.
