Tittel: What are possible worlds?

Abstract:

Philosophers often talk about possible worlds, for example when coming up with counterexamples to proposed theories: a theory is taken to be refuted if we can describe a possible world in which it is false. Necessity is supposed to be truth in all possible worlds, and some philosophers think of propositions as sets of possible worlds. But what are possible worlds? David Lewis has claimed that they are concrete entities, with flesh-and-blood inhabitants just like the world we live in, except that there is no way of getting to these other worlds through space and time. Many have found this proposal highly implausible. But what else could possible worlds be? I will present an alternative proposal defended by Robert Stalnaker and Kit Fine. According to it, possible worlds can be understood as special propositions, namely those which completely describe a way for things to be. It turns out that whether this view works depends on subtle questions about what the space of propositions looks like.
