 Concern About Concern: Rosen 1990 (pp 349–354) discusses an “argument for concern” against modal fictionalism, analogous to an argument from concern famously offered by Saul Kripke against David Lewis’s counterpart theory. (Kripke 1980 p 45) Hubert Humphrey, upon losing an election, cares that he could have won. On the face of it, he does not care that someone like him elsewhere in reality does win. Yet according to David Lewis’s analysis of what it is for Humphrey to have possibly won, his possibly winning amounts to a “counterpart” of Humphrey winning a (counterpart) election in another possible world.
