Approaches to the Impure Logic of Ground

This paper is concerned with the semantics for the logics of ground that derive from a slight variant GG of the logic of Fine (2012b) that have already been developed in deRosset and Fine (2023). Our aim is to outline that semantics and to provide a comparison with two related semantics for ground, given in Correia (2017) and Krämer (2018a). This comparison highlights the strengths and difficulties of these different approaches.
