 I shall not dwell on the details of the Menzies/Pettit position, since the other response to the Brock/Rosen objection has been more influential: the response of Noonan 1994. Noonan claims that the Brock/Rosen objection is not even successful against the letter of the original proposal in Rosen 1990 (Noonan 1994, p. 133). He argues that careful attention to the procedures actually given by Lewis (Lewis 1968) for paraphrasing modal claims into claims in the language of possible worlds will show that “according to the fiction of possible worlds, at any world, there are many worlds” will not be able to be derived, and so the move to “necessarily, there are many worlds” cannot be carried through. Thus if fictionalists stick closely to the possible-worlds “translations” given in Lewis 1968, they will be able to avoid the threatened collapse.
