Denial of the characteristic cognitivist thesis that moral sentences are used to express factual statements. Noncognitivists have proposed various alternative theories of meaning for moral sentences. In Language, Truth and Logic (1936), A. J. Ayer stated the emotivist thesis that moral sentences are not statements at all (see emotivism ). In The Language of Morals (1952), Richard M. Hare
born 1919

that is, are a form of imperative sentence (see prescriptivism ).
