 Yet another approach to defending descriptions would be to employ a “2-dimensionalist” semantics (in the sense of Stalnaker (1978, 1990), Davies and Humberstone (1980)) to account for the behavior of descriptive names in modal environments. Some form of this idea has been offered by Evans (1982), Stanley (1997a, 1997b), Chalmers (2000, 2002), and Jackson (1998). Here the basic idea is that the content of a description picks out different contents in different possible worlds. Accordingly, if we want to evaluate the descriptive content of ‘Aristotle’ in another possible world, we do not use the descriptive content ‘student of Plato…’ in every world, since that is only an appropriate descriptive content for some worlds. In other worlds we will draw on other descriptive contents. As Jackson (1998, 112) puts the idea:
