Abstract

Identity can behave oddly at impossible worlds. Many, and perhaps all, necessary truths about how identity behaves can fail at some impossible world or other. This poses challenges for standard ways of handling domains and satisfaction for objects in worlds. This paper explores a range of options we face here, and evaluates how well these options do at preserving features we might want of both our theories of how identity behaves, and our theories of impossible worlds.
