D. there in 1935 . He was a professor at Yale University from 1939 to 1946, but was denied tenure because of his defense of emotivism . He then taught at the University of Michigan from 1946 to 1977 . He studied in England with Wittgenstein and G.E. Moore . Among his students was Joel Feinberg . </P> <P> He gave the most sophisticated defense of emotivism in the post-war period . In his papers "The Emotive Meaning of Ethical Terms" (1937) and "Persuasive Definitions" (1938), and his book Ethics and Language (1944), he developed a theory of emotive meaning; which he then used to provide a foundation for his theory of a persuasive definition . He furthermore advanced emotivism as a meta - ethical theory that sharply delineated between cognitive, scientific uses of language (used to state facts and to give reasons, and subject to the laws of science) and non-cognitive uses (used to state feelings and exercise influence). </P>
