No philosophical movement has been so violently denounced as the school of "logical positivism." Of all the logical positivists' theories, none has been more bitterly opposed than the "emotive" theory of ethics. The theory's defenders are accused not simply of being mistaken, but of undermining morality.
The Logic of Moral Discourse is a detailed restatement and defense of the emotive theory. It is the first systematic answer to the criticisms leveled at the theory since its introduction to the public in the 1930's.
Professor Paul Edwards confronts the arguments of respected professional philosophers, such as Professor Blanshard, Sir David Ross, and Dr. Ewing, as well as arguments of those whom he describes as the "underworld of philosophy," including C. E. M. Joad and assorted Soviet apologists.
His book does not presuppose familiarity with the subject. The first four chapters are in fact a comprehensive introduction to ethics, with the standard arguments for and against each theory. The very first chapter introduces the reader to the illuminating distinctions formulated by such pioneers as Bertrand Russell, G. E. Moore, and C. L. Stevenson, without which it is impossible to carry on a fruitful discussion of the issues at stake between the logical positivists and the traditional philosophers.
