I happen to have in front of me Charles Parsons' book of essays
_Mathematics in Philosophy_, the 11th chapter of which is titled "Sets
and Modality".  I haven't finished it, but it seems to be treating set
theories with modal operators in the object language.  Free logic is
also involved somehow, but I don't really understand what is going on
yet.
