 One is the project of giving an analysis of modal language, including ability-ascriptions, in terms of possible worlds. The new dispositionalist rejects (CA) and (MA) but she is still, in principle, sympathetic with that project, insofar as she allows that disposition ascriptions themselves may be ultimately understood in terms of quantification over possible worlds. This kind of view is explicitly endorsed, for instance, by Smith (2003). In contrast, Vetter is explicitly opposed to this project, while Steward’s view appears neutral on this question.
