Abstract

The chapter argues that traditional theories of structured propositions of Frege and Russell can’t solve the “problem of the unity of the proposition,” which is to explain how they can be intrinsic, conceptually primary bearers of truth conditions. It further argues that possible-worlds conceptions of propositions can’t bear their truth conditions intrinsically, that they are too coarse-grained even to model propositions, and that theories of truth at a world implicitly presuppose genuine non-possible worlds propositions in order to provide information about meaning.
