Single Idea 7774

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

Full Idea

The possible worlds construal affords an elegant algebra of meaning by way of set theory: e.g. entailment between sentences is just the subset relation - S1 entails S2 if S2 is true in any world in which S1 is true.

Gist of Idea

Possible worlds explain aspects of meaning neatly - entailment, for example, is the subset relation

A Reaction

We might want to separate the meanings of sentences from their entailments (though Brandom links them, see Idea 7765).
