Single Idea 19538

[filed under theme 19. Language / C. Assigning Meanings / 2. Semantics ]

Full Idea

Entailment is modelled in formal semantics as set inclusion. 'Cat' entails 'mammal' because the cats are a subset of the mammals.

Gist of Idea

Entailment is modelled in formal semantics as set inclusion (where 'mammals' contains 'cats')

A Reaction

I would have thought that this was only one type of entailment. 'Travelling to Iceland entails flying'. Travelling includes flying, the reverse of cats/mammals, to a very complex set-theoretic account is needed. Interesting.
