Single Idea 14696

[from 'Two-Dimensional Semantics' by Laura Schroeter, in 19. Language / C. Assigning Meanings / 7. Extensional Semantics ]

Full Idea

The simplest semantic frameworks assign extensions as semantic values of particular expressions. The extension of a name is the thing, of 'cool' is the set of cool things, and sets of ordered pairs for 2-place predicates. The sentence has T or F.

Gist of Idea

Simple semantics assigns extensions to names and to predicates

A Reaction

The immediate well-known problem is different predicates with the same extensions, such as 'renate' and 'cordate'. Possible worlds semantics is supposed to be an improvement to cover this, and to give a semantics for modal talk as well. Sounds good.
