Extensionality and Meaning

This chapter shows that it is formally possible to define the underlying intensional abstraction operation in a first-order extensional language for the theory of properties, relations, and propositions (PRPs). This means that, if one wishes to, one may treat intensional sentences as mere syntactic transformations from fully extensional sentences. Doing this would enable one to conclude that intensionality in language is a mere surface phenomenon, that there is not really a bifurcation of logic into the extensional and the intensional, and that logic is at bottom extensional logic.

Keywords: intensional abstraction; first-order extensional language; semantics; pragmatics
