  Although Hume analyzed money at some length in the 1752 “Of Money,” it now receives systematic attention mainly from economists rather than  philosophers.[1]  In contrast, philosophers still lavish great attention upon the extent, if any, to which language rests upon convention. David Lewis offers a theory of linguistic conventions, while Noam Chomsky and Donald Davidson argue that convention sheds no light upon language. See section 7,  Conventions of language.
