Alasdair MacIntyre: virtue, tradition and the moral life

Alasdair MacIntyre (1929–2025) was one of the most influential moral and political philosophers of the modern era. Born in Glasgow, he spent much of his academic career in the United States. His work challenged the assumptions of modern moral thought and helped revive interest in virtue ethics, the philosophical tradition associated with Aristotle.

MacIntyre is best known for After Virtue, first published in 1981. In it, he argued that contemporary moral debate is often marked by deep disagreement without any shared framework for resolving it. His proposed response was not simply to devise a new set of rules, but to recover an understanding of ethics grounded in human purposes, social practices and traditions of reasoning.

The crisis of modern morality

In After Virtue, MacIntyre presents a striking diagnosis of modern moral culture. People continue to make moral judgements, but, he argues, they often do so using fragments of older moral systems whose original contexts have been lost. As a result, arguments about justice, rights or the good life can become difficult to settle: opposing sides may use the same moral language while relying on very different assumptions.

MacIntyre calls this condition “emotivism”. In its philosophical sense, emotivism is the view that moral statements mainly express feelings or attitudes rather than report facts that can be rationally established. MacIntyre does not suggest that everyone consciously holds this theory. Rather, he argues that modern culture often behaves as if moral disputes ultimately come down to competing preferences or attempts to persuade others.

Virtues and practices

Against this picture, MacIntyre draws on Aristotle’s account of virtue. Virtues are qualities of character—such as courage, justice and honesty—that help people pursue a worthwhile life. They are not merely private traits: they are developed and exercised through participation in shared activities.

MacIntyre describes these activities as “practices”. A practice is a complex, cooperative human activity with standards of excellence and goods that can be achieved through taking part in it. Examples might include medicine, architecture, chess or scientific research. A medical practice, for instance, has standards of skill and care; pursuing those standards can help practitioners and patients attain goods that could not be reached in the same way outside the practice.

He distinguishes these “internal goods” from “external goods”, such as money, status and power. External goods are not necessarily bad, but they can be pursued independently of any particular practice. Institutions are needed to support practices, yet they can also become preoccupied with external rewards. For MacIntyre, virtues help practitioners protect the standards and internal goods of their work.

Narrative and the shape of a life

MacIntyre also argues that a human life is best understood as a narrative. People are not simply a series of disconnected choices: they inherit circumstances, take on responsibilities and pursue goals over time. To ask what a particular action means, he suggests, is often to ask how it fits into the story of a person’s life.

This idea connects individual moral development with community. People learn what counts as a worthwhile goal through relationships, institutions and histories they did not create alone. A life’s direction is therefore shaped both by personal choices and by the traditions and social settings in which those choices become intelligible.

Tradition and rational debate

For MacIntyre, moral reasoning cannot be separated from tradition. By “tradition”, he means more than passive loyalty to inherited customs. A living tradition is an ongoing argument about the goods and standards that define it. It can be questioned, criticised and developed by its members.

This account offers an alternative to the idea that rational thought must begin from a neutral standpoint outside history and culture. MacIntyre argues that traditions can engage critically with one another, and that a tradition may learn from its own failures or from the arguments of its rivals. His approach has prompted debate about whether moral reasoning can be both rooted in particular communities and open to wider criticism.

Politics, community and dependence

MacIntyre’s criticism of modern moral and political life extends to individualism and bureaucracy. He was sceptical of political approaches that treat people as isolated choosers, detached from the relationships and shared activities that give life meaning. He also questioned whether the modern state and market can, by themselves, provide the forms of community needed for a flourishing life.

In Dependent Rational Animals (1999), he turned more directly to human vulnerability and mutual dependence. People experience illness, disability and reliance on others at different stages of life. MacIntyre argued that a sound account of ethics must take these facts seriously, recognising the virtues involved in giving and receiving care.

A changing philosophical journey

MacIntyre’s intellectual life was not a simple or unchanging programme. His early work engaged with Marxism, and he later became a prominent critic of modern liberal moral philosophy. He was received into the Roman Catholic Church in 1983, and his mature work brought Aristotelian ethics into conversation with the thought of Thomas Aquinas. Across these changes, he continued to examine how moral ideas are shaped by history and social life.

MacIntyre’s continuing influence

MacIntyre’s work has influenced philosophers, theologians, political thinkers and scholars in fields including education, medicine and professional ethics. His account of practices has encouraged discussion about what it means to do good work, while his emphasis on virtue has helped make character and moral formation central topics in contemporary ethics.

His arguments remain contested. Critics have questioned his diagnosis of modern moral disagreement, his emphasis on tradition and the practical implications of his political thought. Yet his central challenge endures: can moral life be understood through rules and individual preferences alone, or does it depend on shared practices, relationships and ideas about what human beings are for?

By insisting that ethics concerns the shape of a whole life—not merely isolated decisions—MacIntyre gave modern philosophy a powerful reason to return to questions of character, community and the common good.
