Aristotle's view that ethics is about building good character, and that the goal of life is eudaimonia, human flourishing.

The idea

The idea: the key question is not 'which act is right?' but 'what kind of person should I be?' Everyone aims at eudaimonia, 'flourishing', a whole life lived well. We get there through virtues, stable traits built by habit, as a builder learns by building. Each virtue is a mean between extremes: courage between cowardice and recklessness, generosity between stinginess and waste. Practical wisdom (phronesis) finds the mean case by case. The main objection: it offers little concrete guidance in hard dilemmas.

Why it matters

With duty-based ethics and utilitarianism it is one of the three main approaches to ethics today, revived since 1958 after centuries in the background.

Think of it like

Like a property manager's judgement: no manual covers every case, so you build instincts through experience and good mentors.

Where it comes from

The Nicomachean Ethics, ten books probably based on lecture notes, survives complete; Anscombe (1958) and MacIntyre's After Virtue (1981) led its modern revival.

Still debated

Scholars debate whether eudaimonia means a balanced life of many goods or, as Book X suggests, mainly the life of contemplation.

Connections (4)

▸Aristotle developed Virtue ethics and eudaimonia (Nicomachean Ethics)Well documented

The connection

Aristotle built virtue ethics on his view of human nature: every living thing has a characteristic function, and a human's is to use reason well. Doing that across a whole life, with good character, friends and enough means, is eudaimonia. He laid it out in lectures later edited as the Nicomachean Ethics.

When and how

Athens, at the Lyceum, around 335–322 BC; the title may honour his son Nicomachus, who possibly edited it, or his father of the same name.

How we know

The Nicomachean Ethics and the related Eudemian Ethics survive and are accepted as his; ancient catalogues of his works list them.

Debates and open questions

How the two Ethics relate, which came first, and whether his 'function argument' really supports his conclusions are long-standing debates.

▸Virtue ethics and eudaimonia (Nicomachean Ethics) gives Aristotle's answer to What is a good life?Mostly agreed

The connection

Aristotle answered that the good life is eudaimonia, 'flourishing', achieved by practicing virtues such as courage, generosity and justice until they become habits. Each virtue is a middle path between extremes: courage lies between cowardice and recklessness. Friends, luck and modest wealth help too.

When and how

Athens, at Aristotle's Lyceum, about 335–323 BC, in lectures later edited as the Nicomachean Ethics.

How sure are we?

The Nicomachean Ethics survives and states the view directly; it has been taught for centuries and revived in modern ethics since the late 1950s.

Debates and open questions

Whether Aristotle's best life is philosophical contemplation (Book 10) or active civic virtue is a long-standing dispute among interpreters.

▸Virtue ethics and eudaimonia (Nicomachean Ethics) was revived by MacIntyre, Sandel and the communitariansWell documented

The connection

MacIntyre's After Virtue argued that modern ethics, built on rules and rights, had lost the framework that once made moral words meaningful. His remedy was Aristotle: virtues as traits developed through shared practices, inside communities with a common idea of the good life. That revival also fed the communitarian case against Rawls.

When and how

Alasdair MacIntyre, a Scottish-born philosopher teaching in the United States, published After Virtue in 1981; Elizabeth Anscombe's 1958 essay 'Modern Moral Philosophy' had issued the first call.

How we know

After Virtue names Aristotle's ethics as the tradition to recover; with Anscombe's essay, it is widely credited for the late-20th-century revival of virtue ethics.

Debates and open questions

Sandel and Taylor drew less on Aristotle than MacIntyre did, and MacIntyre rejected the communitarian label, so how far this link covers the whole group is debated.

▸The capabilities approach (Sen and Nussbaum) draws on Virtue ethics and eudaimonia (Nicomachean Ethics)Well documented

The connection

Nussbaum based her list of central capabilities on Aristotle's idea that a good life is one of flourishing (eudaimonia), using distinctively human powers well. Government's job, as Aristotle also held, is to give citizens the conditions to flourish. Sen draws on Aristotle too, and on Adam Smith.

When and how

Nussbaum's 'Nature, Function, and Capability: Aristotle on Political Distribution' (1988), and later Women and Human Development (2000).

How we know

Nussbaum, a leading Aristotle scholar, cites him explicitly as the source of her approach.

Debates and open questions

Critics ask whether an Aristotelian list of the good life fits diverse societies; Nussbaum later reframed her list within political liberalism rather than full Aristotelianism.
