Tradition, Rationality, and Virtue provides the first comprehensive and detailed treatment of the work of Alasdair MacIntyre. In this book Thomas D'Andrea presents an accessible critical study of the full range of MacIntyre's thought across ethical theory, psychoanalytic theory, social and political philosophy, Marxist theory, and the philosophy of religion. Moving from the roots of MacIntyre's thought in ethical inquiry, this book examines MacIntyre's treatment of Marx, Christianity, and the nature of human action and discusses in depth the development and applications of MacIntyre's After Virtue project. The book culminates in an examination of major internal and external criticisms of MacIntyre's work and a consideration of its future directions.
