The Logic of Comparatives

Bayne was recently considering the logic of comparatives, elsewhere.

He was considering whether x is --er than y implies or entails that x is --. He argued that it does, or it doesn't. On context.

Incidentally, Chapman has this quote by Grice, "I am known as having been no foe to the idea that an alleged entailment ends up being an implicature".

Entailment was apparently coined -- in a manner of speaking -- by Moore.

Most of Grice's theory can be seen as a fight, and a balance between the entailment of Moorean pedigree and the implicature which was all his own.

--- Compared to the centrality of Moore's concept of entailment -- and I'm an Oxford person, so take that as a triple compliment --, the Austin notion of force, or the Strawson notion of presupposition, pale in comparison.
