MacIntyre Alasdair (b.1929), British-American philosopher and eminent contemporary representative of Aristotelian ethics. He was born in Scotland, educated in England, and has taught at universities in both England and (mainly) the United States. His early work included perceptive critical discussions of Marx and Freud as well as his influential A Short History of Ethics. His most discussed work, however, has been After Virtue (1981), an analysis and critique of modern ethical views from the standpoint of an Aristotelian virtue ethics. MacIntyre begins with the striking unresolvability of modern ethical disagreements, which he diagnoses as due to a lack of any shared substantive conception of the ethical good. This lack is itself due to the modern denial of a human nature that would provide a meaning and goal for human life. In the wake of the Enlightenment, MacIntyre maintains, human beings are regarded as merely atomistic individuals, employing a purely formal reason to seek fulfillment of their contingent desires. Modern moral theory tries to derive moral values from this conception of human reality. Utilitarians start from desires, arguing that they must be fulfilled in such a way as to provide the greatest happiness (utility). Kantians start from reason, arguing that our commitment to rationality requires recognizing the rights of others to the same goods that we desire for ourselves. MacIntyre, however, maintains that the modern notions of utility and of rights are fictions: there is no way to argue from individual desires to an interest in making others happy or to inviolable rights of all persons. He concludes that Enlightenment liberalism cannot construct a coherent ethics and that therefore our only alternatives are to accept a Nietzschean reduction of morality to will-to-power or to return to an Aristotelian ethics grounded in a substantive conception of human nature.
MacIntyre’s positive philosophical project is to formulate and defend an Aristotelian ethics of the virtues (based particularly on the thought of Aquinas), where virtues are understood as the moral qualities needed to fulfill the potential of human nature. His aim is not the mere revival of Aristotelian thought but a reformulation and, in some cases, revision of that thought in light of its history over the last 2,500 years.
MacIntyre pays particular attention to formulating concepts of practice (communal action directed toward a intrinsic good), virtue (a habit needed to engage successfully in a practice), and tradition (a historically extended community in which practices relevant to the fulfillment of human nature can be carried out). His conception of tradition is particularly noteworthy. His an effort to provide Aristotelianism with a historical orientation that Aristotle himself never countenanced; and, in contrast to Burke, it makes tradition the locus of rational reflection on and revision of past practices, rather than a merely emotional attachment to them. MacIntyre has also devoted considerable attention to the problem of rationally adjudicating the claims of rival traditions (especially in Whose Justice? Which Rationality?, 1988) and to making the case for the Aristotelian tradition as opposed to that of the Enlightenment and that of Nietzscheanism (especially in Three Rival Versions of Moral Inquiry, 1990).
