The World Is Not Enough: An Enquiry into Realism about Modality

by Ryan J. Comeau

I will examine various putative criteria for realism about modality, rejecting some and accepting others. I then will use the criteria to evaluate the views of Lewis and Stalnaker. In the end I argue that, while Lewis’ account satisfies the conditions that I propose, we need not require that possible worlds are concrete if we want to be realists about possible worlds. Further, I will argue that it is questionable whether Stalnaker’s account should count as realist.
