Modalne argumenty teistyczne (Modal Theistic Arguments)

The aim of Oppy’s paper is to provide a general ground for rejecting all kinds of modal theistic arguments. The author claims that all such arguments are questionbegging – before proving the existence of God (defined as a being which exists in every possible world) theistic modalist must assume it when choosing his account of logical space (no matter which modal theory it relies on: Lewis’ modal realism, ersatz modal realism, combinatorialism or fictionalism). Two concrete arguments, Plantinga’s ontological argument and Leftow’s cosmological argument, are examples given by Oppy – both have premises which justification must refer to a non-modal question “Does God actually exist?”, concerning the nature of logical space.Oppy rejects suggestion that problems with modal theistic arguments show that there is simply something wrong with our standard modal analyses in terms of possible worlds. According to Oppy, problems with higher-level judgments about the nature of logical space are problems with propositional attitudes, not with modality, andthey need an analysis distinct from the analysis of ground-level modal judgments.
