 So the state of play seems to be this: while the Brock/Rosen style objection remains something for a modal fictionalist to be wary of when constructing the fiction of possible worlds, it is possible to avoid the objection by being suitably careful about what fictionalist biconditionals to employ: and if Noonan is right, strict adherence to the fictionalist modification of the equivalences offered by Lewis 1968 provides one suitable way of being careful. It is not uncontroversial, of course, that Noonan’s strategy is the one a modal fictionalist should employ: Divers 1999a and 1999b, Kim 2002 and Divers and Hagen 2006 argue that it is not.
