Three-Dimensional Semantics

  • Gregory Bochner


How can identity sentences involving distinct names be informative? Any theory of names facing the problem of informativity will need to appeal to descriptions. The crucial question is: at which level do descriptions play a role? Kripke showed that descriptions neither constitute nor fix the semantic contents of names. At the same time, his Millian views imply the problematic existence of modal illusions: some necessary truths are knowable only aposteriori even though there is no possible world in which they don’t hold. I sketch a new, metasemantic strategy that purports to avoid modal illusions within a referentialist framework: the relevant descriptions describe not extensions (descriptivism), not intensions (twodimensionalism), but names themselves (three-dimensionalism).
