Aristotle · Nicomachean Ethics

The ten books.

The chapters of this site wander the argument by theme. The Ethics itself is built in ten books, each handed to the next. This is the work as Aristotle ordered it — and where, on this site, you have already met each part.

  1. Book One — The Good for Man

    1094a – 1103a

    Every pursuit aims at some good; the good we seek for its own sake and never for the sake of anything else is happiness — eudaimonia. The function argument concludes that the human good is activity of the soul in accordance with virtue.

  2. Book Two — Virtue of Character

    1103a – 1109b

    Moral virtue is not given by nature but formed by habit — we become just by doing just acts. Each virtue is a mean between two vices, one of excess and one of deficiency, fixed by reason.

  3. Book Three — Choice, and Two Virtues

    1109b – 1119b

    Voluntary action, deliberation, and choice — the ground on which praise and blame can rest. Then the first two virtues examined in full: courage and temperance.

  4. Book Four — The Social Virtues

    1119b – 1128b

    Liberality and magnificence in the handling of money; magnanimity and proper ambition in the handling of honour; good temper; and the virtues of company — truthfulness, wit, and friendliness.

  5. Book Five — Justice

    1129a – 1138b

    Justice in its widest sense is the whole of virtue exercised toward others. As a particular virtue it divides into the distributive — a fair share — and the corrective — a fair remedy.

  6. Book Six — Practical Wisdom

    1138b – 1145a

    The virtues of the intellect, and phronēsis above all: the practical wisdom that perceives the mean in the particular case, where no rule can reach. Virtue of character and practical wisdom need each other.

  7. Book Seven — Weakness of Will

    1145a – 1154b

    Akrasia: how a person can see the good clearly and still fail to do it — against Socrates, who thought such a thing impossible. The book closes with a first account of pleasure.

  8. Book Eight — Friendship

    1155a – 1163b

    Why no one would choose to live without friends, and the three kinds of friendship — those of utility, of pleasure, and the lasting friendship between good people who wish each other well.

  9. Book Nine — Friendship, Continued

    1164a – 1172a

    Self-love, goodwill, and concord; the friend as "another self"; and the question of why even a happy, self-sufficient person still needs friends to live well.

  10. Book Ten — Pleasure, and the Contemplative Life

    1172a – 1181b

    The true place of pleasure in a good life; then the final claim — that contemplation, theōria, is the highest happiness, the activity nearest the divine — and the turn toward politics that the Ethics leaves open.
