Alasdair MacIntyre

Biography

Alasdair Chalmers MacIntyre was born on January 12, 1929, in Glasgow, Scotland, and died on May 21, 2025. He studied classics and philosophy at the University of London and at the University of Manchester, completing his graduate work in the early 1950s. His early intellectual life was marked by political engagement: he joined the Communist Party of Great Britain as a young man, left it after the Soviet suppression of the Hungarian uprising in 1956, and moved through a series of left-wing intellectual commitments before concluding that neither Marxism nor liberal individualism could supply an adequate account of moral life.

MacIntyre held academic posts across a remarkable range of institutions, including the Universities of Manchester, Leeds, and Oxford, and, in the United States, Princeton, Brandeis, Boston University, Vanderbilt, the University of Notre Dame, and Duke University. His migration between Britain and America, and between departments of philosophy, sociology, and political science, reflected the deliberately interdisciplinary character of his work. In the late 1970s and early 1980s he converted to Roman Catholicism, and his subsequent thought drew increasingly on the Thomist tradition, integrating Aristotelian ethics with a theology of human nature and beatitude. The Stanford Encyclopedia of Philosophy notes that this trajectory, from analytic philosophy through Marxism to Thomistic Aristotelianism, is not a series of abandoned positions but a continuous inquiry into how human action can be understood and evaluated without the fragmented conceptual resources of modernity.

Historical Context

MacIntyre wrote in a philosophical climate dominated by two traditions he regarded as failures. The first was the analytic and emotivist legacy according to which moral language expresses attitude rather than truth, a view he associated with the collapse of shared moral standards into expressions of preference. The second was the Enlightenment project of founding morality on universal reason alone, independent of teleology and tradition, which he argued had produced not agreement but interminable disagreement. The moral philosophy of Kant and the utilitarianism of Bentham and Mill were, for MacIntyre, the central expressions of this failed project, and the persistence of unresolved debate between them was itself evidence of the fragmentation he diagnosed.

After Virtue, published in 1981, appeared in the same intellectual moment as the revival of virtue ethics by Anscombe and Foot, and alongside the communitarian critique of liberalism advanced by Charles Taylor, Michael Sandel, and Michael Walzer. But MacIntyre's position was more radical than communitarianism. Where liberal communitarians sought to supplement procedural justice with a shared conception of the good, MacIntyre argued that the very categories of modern moral thought had been rendered incoherent by the loss of the Aristotelian framework of teleology, and that recovery required not reform but a return to a tradition-constituted inquiry. The Internet Encyclopedia observes that this placed MacIntyre in uneasy relation to the liberal political order, whose institutions he regarded as incapable of sustaining the virtues.

Core Ideas

The central argument of After Virtue is that modern moral discourse is the surviving fragment of a once-coherent tradition that has lost its background. MacIntyre compares the moral language of the present to the fragments of a destroyed civilization: words such as rights, utility, virtue, and obligation persist, but the contexts that gave them meaning have disappeared. The result is a culture in which moral debate is interminable because the participants do not share the premises that would allow resolution. Each side invokes an incommensurable conceptual scheme, and no neutral standpoint exists to adjudicate between them. This diagnosis of the emotivist condition is the premise from which MacIntyre's constructive project begins.

To recover a coherent account of virtue, MacIntyre develops the concept of a practice. A practice is a coherent and complex form of socially established cooperative activity through which goods internal to that activity are realized. Internal goods are those that can only be specified and appreciated in terms of the practice itself, such as the achievement of a chess master, and they stand in contrast to external goods, such as money or prestige, which can be obtained by other means. MacIntyre then defines a virtue as an acquired human quality the possession and exercise of which tends to enable us to achieve those goods which are internal to practices and the lack of which effectively prevents us from achieving any such goods. The virtues are therefore not free-standing traits but dispositions whose intelligibility depends on the practices they sustain.

The second concept is the narrative unity of a human life. MacIntyre argues that actions are intelligible only within the narratives that give them point, and that a life is not a sequence of isolated episodes but a quest for the good that organizes its particulars. The virtues are those qualities that sustain the narrative quest, that enable a person to pursue the good across the unpredictability and vulnerability of human life. This is an explicitly teleological framework: the virtues are intelligible only relative to a conception of the human telos, and the loss of teleology in modern thought is the loss that makes virtue unintelligible.

The third concept is tradition. MacIntyre holds that rational inquiry, including moral inquiry, is always tradition-constituted. There is no view from nowhere, no neutral standpoint outside all traditions from which to evaluate them. Traditions are extended arguments across generations about the goods that constitute them, and they develop through encounters with rivals and with internal crises, what MacIntyre calls epistemological crises, that can be resolved only by resources the tradition itself cannot yet supply. A tradition proves itself rational not by escaping history but by its capacity to explain its rivals more adequately than they explain themselves. This commitment to tradition-constituted rationality is the most controversial element of MacIntyre's thought and the one that most sharply distinguishes him from the Enlightenment universalism he criticizes.

Philosophy

MacIntyre's philosophy is a sustained argument that the virtues require a teleological and tradition-constituted framework that modernity has lost. His account of virtue draws on Aristotle, but it is not a simple restoration of Aristotle. MacIntyre argues that Aristotle's own framework depended on a metaphysical biology and a polis-centered politics that are no longer available, and that virtue must be re-grounded in practices, narratives, and living traditions. His later work, especially Dependent Rational Animals (1999), supplements the Aristotelian account with an emphasis on human vulnerability and dependency, arguing that the virtues of acknowledged dependence are essential to any adequate ethics and that they require the political form of local community.

The Thomist dimension of MacIntyre's thought deepened over time. He came to hold that Thomas Aquinas had achieved the most adequate synthesis of Aristotelian philosophy with a theology of human nature, and that the recovery of virtue required the recovery of this synthesis. This does not make his argument inaccessible to non-theists, since much of the analysis of practices, narratives, and traditions proceeds on philosophical rather than theological grounds, but it does mean that MacIntyre's ultimate account of the human telos is theological. The Stanford Encyclopedia notes that this has generated debate over whether MacIntyre's critique of modernity depends on premises that only a Thomist could accept.

Major Works

After Virtue (1981; third edition 2007) is MacIntyre's most influential work and the foundation of contemporary virtue ethics. It diagnoses the incoherence of modern moral discourse and reconstructs the Aristotelian framework of virtue, practice, narrative, and tradition. Whose Justice? Which Rationality? (1988) extends the argument to the history of moral traditions, examining Aristotle, Augustine, Aquinas, Hume, and the liberal tradition as rival, tradition-constituted forms of rational inquiry. Three Rival Versions of Moral Enquiry (1990) compares the encyclopedic, genealogical, and Thomistic traditions of moral understanding. Dependent Rational Animals (1999) revises and deepens the account of virtue by foregrounding human animality, vulnerability, and dependence. Together these works constitute one of the most ambitious projects in late twentieth-century moral philosophy.

Famous Quotes

MacIntyre's most cited passage defines virtue in terms of practice. In After Virtue he writes that a virtue is an acquired human quality the possession and exercise of which tends to enable us to achieve those goods which are internal to practices, and the lack of which effectively prevents us from achieving any such goods. This formulation, from Chapter 14 of the third edition, has become the standard reference point for his account. The closing image of After Virtue, that what matters at this point is the construction of local forms of community within which civility and the intellectual and moral life can be sustained through the new dark ages, is also widely quoted as an expression of his stance toward modernity.

Related Thinkers

MacIntyre's principal philosophical ancestor is Aristotle, whose teleological ethics supplies the framework that modernity, in MacIntyre's diagnosis, lost. Plato is a more distant but formative presence in the Greek tradition of inquiry MacIntyre seeks to recover. Nietzsche functions as both the sharpest critic of the Enlightenment's moral remnants and a rival whose genealogy MacIntyre answers with his own account of tradition-constituted rationality. Kant represents the Enlightenment universalism whose failure MacIntyre diagnoses, and whose deontology he treats as one fragment of the lost Aristotelian whole. Confucius offers the most significant non-Western parallel, since Confucian ethics likewise grounds virtue in tradition, practice, and the cultivation of character through ritual and relationship. These relations should be read as a sustained argument about whether morality can be made intelligible without the resources of teleology and tradition, not as a simple lineage.
