God's Extended Mind

Abstract

The traditional doctrine of divine omniscience ascribes to God the fully exercised power to know all truths. but why is God’s excellence with respect to knowing not treated on a par with his excellence with respect to doing, where the latter requires only that God have the (exercised or unexercised) power to do all things? The prima facie problem with divine ‘omni-knowledgeability’ – roughly, being able to know whatever one wants to know whenever one wants to know it – is that knowledge (whether occurrent or dispositional) requires an internal representation, whereas mere ‘knowledgeability’ does not. I argue to the contrary that knowledge does not require an internal representation, and that even if it did, an omni-knowledgeable God would satisfy this requirement. omni-knowledgeability therefore represents a distinct understanding of God’s cognitive excellence while satisfying the traditional insistence on full omniscience.
