Description:R.M. Hare is one of the foremost moral philosophers of this century and this volume contains 13 essays by well-known philosophers which discuss Hare's thinking. The essays cover a wide range of issues including universalizability, moral psychology, and the role of common-sense moral principles. A special feature of the book is Professor Hare's responses to his critics with both an essay and detailed, point-by-point criticism. In 1981, Oxford University Press published Hare's "Moral thinking", which built on his earlier metaethical work to develop a utilitarian normative position which differed from other formulations of utilitarianism .
