 Initial motivation for MD normativism is furnished by the arbitrary, contingent, and “man-made” nature of the connection between linguistic expressions and their meanings. Observed by philosophers since ancient times, the nature of this connection suggests that it might be established by convention. But plausible as such conventionalism might seem, earlier discussions have shown it to be quite controversial (cf. Davidson 1984a; Dummett 1986). If conventions are to play a role in an informative account of meaning, we cannot simply claim that it, for instance, is a convention of English that “green” means green. Rather, the relevant conventions would need to be specified in non-semantic terms (cf. Davidson 1984a; Glüer 2013).
