Alasdair MacIntyre believes the history of philosophy is profoundly relevant to contemporary life and thought and the philosophical systems of such figures as Aristotle and Aquinas could and ought to be used as viewpoints from which contemporary thought itself can be criticized. For MacIntyre the history of philosophy is not necessarily a history of progress in which our grasp of truth is improving. Rather he argues earlier traditions within philosophy are in many respects far more intellectually adequate than contemporary systems of thought and people ought to in some significant ways return to these earlier systems for first principles. In this respect he may be referred to as a philosophical conservative.
Alasdair MacIntyre has written thirty-three books in philosophy religion and theology since his first book Marxism: An Interpretation appeared in 1953. Other notable publications include the influential triumvirate of recent works: After Virtue: A Study in Moral Theory (1981); Whose Justice? Which Rationality? (1988); and Three Rival Versions of Moral Enquiry: Encyclopaedia Genealogy and Tradition (1990). He received a Metcalf Prize in 1974 and a DHA from Swarthmore College in 1983.
