Possible Worlds, The Lewis Principle, and the Myth of a Large
... We’ve systematized our modal inferential practices and our philosophical understanding of those practices. We’ve grounded the meaningfulness of unanalyzed modal beliefs and possible world talk in the inferential roles this kind of talk plays in our discourse: the meaning of ‘world’ is a (objectified ...

We proved in [3] that for every chain M = (A, <, P) such that (A, <) contains a sub-interval of type or −, M is not maximal with respect to MSO logic, i.e., there exists an expansion M of M by a predicate which is not MSO definable in M , and such that the MSO ...
