This thesis is a reply to John McDowell's objection to Dummett's immodest theory of meaning. McDowell argues that, given the explanatory burden and the restriction within which the theory must discharge its task, Dummett's immodest theory entails a reductive conception of meaning. In this thesis, I argue that McDowell has misunderstood the nature of Dummett's restriction. I then offer a correct interpretation of the restriction and show how a satisfaction of it by Dummett's immodest theory of meaning does not render a reductive conception of meaning.
