Happiness as Activity of Soul in Accordance with Virtue

The Quote

"The human good proves to be activity of soul in accordance with virtue, and if there are several virtues, in accordance with the best and most complete virtue."

— Aristotle, Nicomachean Ethics, 1098a

Original language: Greek

Historical Context

This passage comes from Book I of Aristotle's Nicomachean Ethics, a work compiled from lecture notes in the fourth century BCE. In the opening books, Aristotle works toward a definition of the highest human good (telos) by examining what is distinctive about human life. He begins from the observation that every art, inquiry, and action aims at some good, and asks what the ultimate good for a human life might be.

Aristotle's method is teleological: he assumes that human beings have a characteristic function (ergon), just as a flutist or sculptor has a function, and that the human good consists in performing that function well. The passage represents the conclusion of this argument: since the distinctive human function is rational activity, the human good is rational activity performed in accordance with virtue.

Meaning

The passage defines happiness (eudaimonia) not as a feeling, a state of mind, or a possession, but as an activity. Happiness is something one does, not something one has. Specifically, it is the activity of the rational soul performed in accordance with virtue — that is, performed excellently.

The qualification "if there are several virtues, in accordance with the best and most complete virtue" acknowledges Aristotle's recognition that virtue is not a single quality but a family of excellences (courage, temperance, justice, practical wisdom, etc.). The highest happiness involves not just any virtue but the most complete one — which Aristotle later identifies as contemplative wisdom (sophia), the exercise of the highest rational faculty.

Philosophical Interpretation

Aristotle's definition of happiness as activity contrasts sharply with conceptions that locate happiness in pleasure, wealth, or honor. Pleasure is a byproduct of activity, not the activity itself; wealth is a means to an end, not an end in itself; honor depends on others and is therefore not fully within one's own control. Happiness as virtuous activity, by contrast, is self-sufficient — it is chosen for its own sake and depends on the agent's own excellence rather than on external circumstances.

The emphasis on activity rather than disposition is crucial. Aristotle holds that possessing virtue is not sufficient for happiness; one must also exercise it. A person who is virtuous but asleep or inactive is not happy in the relevant sense. Happiness requires the active expression of virtue over a complete life — a single virtuous action does not make one happy, any as a single swallow does not make a summer.

The phrase "activity of soul" connects Aristotle's ethics to his psychology. The soul (psyche) is the form or organizing principle of the living body, and its distinctive human function is rational activity. Happiness is therefore not an addition to human nature but its fulfillment — the full expression of what it means to be a rational being.

Related Concepts

• Happiness: Aristotle redefines happiness from a subjective feeling to an objective activity — the excellent exercise of rational capacities.
• Virtue: Virtue is the quality that makes an activity excellent; without it, rational activity does not constitute the human good.
