Virtue ethics is a tradition that emphasizes the role of character and the virtues in moral philosophy, focusing on what kind of person one should be rather than on rules or consequences. Its founding figure is Aristotle, who developed the approach in his Nicomachean Ethics. For Aristotle, the highest human good is eudaimonia, often translated as happiness or flourishing, which is achieved by living a life of virtue in accordance with reason. Eudaimonia is not a momentary state of pleasure but the comprehensive fulfillment of human capacities over a complete life.
Aristotle's signature contribution is the doctrine of the mean, which holds that moral virtue is a mean between two extremes, one of excess and one of deficiency. Courage, for example, is the mean between the excess of recklessness and the deficiency of cowardice; generosity lies between wastefulness and miserliness. The doctrine does not prescribe mechanical moderation but requires situational judgment, which is supplied by phronesis, or practical wisdom. Phronesis is the intellectual virtue that allows a person to discern the right course of action in particular circumstances, balancing competing considerations and applying general principles sensitively. Among the cardinal virtues identified by Aristotle, courage involves bravery in the face of fear, temperance denotes moderation in desires, and justice means giving others what is due to them.
After centuries of dominance by rule-based and consequence-based theories, virtue ethics experienced a major revival in the late twentieth century. Alasdair MacIntyre's After Virtue (1981) argued that modern moral philosophy had lost coherence and advocated a return to an Aristotelian tradition embedded in social practices. MacIntyre claimed that virtues cannot be understood apart from the communal contexts in which they are cultivated and exercised. This renewed emphasis on character, communal life, and the cultivation of excellence has shaped contemporary moral philosophy and offered a powerful alternative to both Kantian deontology and utilitarianism, particularly in fields like professional ethics and the ethics of care.
