Abstract

Le Verrier’s attempts to use ‘Vulcan’ to refer to an inter-Mercurial planet failed: Vulcan is a mere mythical entity. But, as the previous sentence demonstrates, we now use ‘Vulcan’ not in failed attempts to refer to a planet, but in seemingly successful attempts to refer to a mythical entity. These different uses of ‘Vulcan’ present critical pragmatics with a dilemma. On one horn, my use of ‘Vulcan’ cannot be conditionally co-referential with Le Verrier’s uses, because he failed to refer (to a planet), whereas I (seemingly successfully) refer to a mythical entity. But, on the other horn, such uses of ‘Vulcan’ are not a simple case of nambiguity, because what I say in uttering ‘Vulcan is a mythical entity’ is incompatible with Le Verrier’s assertion of, e.g., ‘Vulcan is hot’. I propose to escape this dilemma by appeal to a different relation between uses of names which I call converse conditional co-reference.
