Abstract
THE emotive theory of ethics made its first brief and rather tentative appearance in The Meaning of Meaning by Ogden and Richards in 1922. It did not gain currency, however, nor receive anything like a complete formulation until it was adopted by Logical Positivism, and in particular by A J Ayer in Language, Truth and Logic. Ayer’s account was soon superseded by that of Charles L Stevenson, whose views were finally elaborated in Ethics and Language in 1942. This, the classic statement of emotivism, is one of the great works of moral philosophy of this century, worthy to be ranked with the Principia Ethica of G E Moore.
