The contribution to contemporary philosophy of Alasdair MacIntyre is enormous. His writings on ethics, political philosophy, philosophy of religion, philosophy of the social sciences and the history of philosophy have established him as one of the philosophical giants of the last fifty years. His best-known book, After Virtue (1981), spurred the profound revival of virtue ethics. Moreover, MacIntyre, unlike so many of his contemporaries, has exerted a deep influence beyond the bourns of academic philosophy. This volume focuses on the major themes of MacIntyre's work with critical expositions of MacIntyre's views on the history of philosophy, the role of tradition in philosophical inquiry, the philosophy of the social sciences, moral philosophy, political theory, and his critique of the assumptions and institutions of modernity. Written by a distinguished team of philosophers, this volume will have a wide appeal outside philosophy to students in the social sciences, law, theology, and political theory.
