 Let us transpose this to the one-person case: I am talking to myself, i.e. thinking — considering whether if \(A, B\). The context set is the set of worlds compatible with what I take for granted, i.e. the set of worlds not ruled out, i.e. the set of worlds which are epistemically possible for me. Let \(A\) be epistemically possible for me. Then the pragmatic constraint requires that for any world in the context set, the nearest \(A\)-world to it is also in the context set. Provided you and I have different bodies of information, the proposition I am considering when I consider whether if \(A, B\) may well differ from the proposition you would express in the same words: the constraints on nearness differ; worlds which are near for me may not be near for you.
