[catalogued under 19. Language / C. Assigning Meanings / 8. Possible Worlds Semantics]

Full Idea

Semantic values in extensional semantics are extensions, like individuals for terms, and sets for predicates. In modal semantics we have intensions, functions from worlds to appropriate extensions.

Gist of Idea

Extensional semantics has individuals and sets; modal semantics has intensions, functions of world to extension
