God and Modal Concretism
In this paper I examine Graham Oppy’s claim that all modal theistic arguments “must be question-begging,” since they presuppose a particular account of the nature of possible worlds “which can only be supported by the further claim that God actually exists.” I argue that Oppy is mistaken here. For even if theism implies the falsity of (say) David Lewis’s concretist account of worlds, a proof for God that starts from this assumption is not thereby ensnared in a vicious circularity. I go on to present some materials for a modal theistic proof immune to all of Oppy’s criticisms.
