 Even so, the appeal to stipulation is more like a promissory note than the satisfaction of an explanatory obligation. The appeal to stipulation puts off for another occasion any attempt to resolve how we succeed at doing what we take for granted that we manage somehow to do: namely, how we succeed at referring to the right individual, by means of our stipulative effort. There has to be some “reason the stipulated situation, when we use a name, contains the object it does” (Sidelle 1995, p. 99n.4) rather than likely competitors. It is hardly obvious what that reason would be. To see why, consider that in order successfully to stipulate that a name is to follow just you, as a rigid and therefore transworld tracking device, our stipulative effort has to be able, across worlds, to allow us to distinguish what is you from what is not you but is instead your body (say: assume you are not your body). How is this to be done without specifying criteria, if you were with your body when your parents smiled in your direction and baptized you with a rigid designator, saying “We have decided on a name for the birth certificate: …,” thereby stipulating that you are to be called by the name they chose for you? “It is not by magic,” as Jackson (1998, p. 82) reminds us, that your name “picks out what it does pick out” rigidly—namely you—despite the competition against you presented by a different candidate for designation—your copresent body.
