Who really said it

We are what we repeatedly do. Excellence, then, is not an act, but a habit

Q: Did Aristotle say "We are what we repeatedly do. Excellence, then, is not an act, but a habit"?

No. The memorable wording was written by Will Durant, not Aristotle. It appears in Durant's bestseller The Story of Philosophy (1926), where he compressed Aristotle's argument in the Nicomachean Ethics (Book II) into one crisp sentence of his own. Aristotle never wrote this line in any surviving work — the thought is Aristotelian, but the phrasing is Durant's.

Provenance

The source

Actual author: Will Durant
Work: The Story of Philosophy
First published: 1926 (New York: Simon & Schuster)
Summarizing: Aristotle, Nicomachean Ethics, Book II

Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. ‘These virtues are formed in man by his doing the actions’ … we are what we repeatedly do. Excellence, then, is not an act but a habit. The Story of Philosophy, p. 87 — chapter on Aristotle, “Ethics and the Nature of Happiness”

Durant’s original prints “not an act but a habit” without the comma; the now-standard “not an act, but a habit” is a later, lightly re-punctuated variant. The words inside the single quotation marks are Durant citing a translation of Aristotle — the epigram itself is his own.

How we traced it

The wording debuts in Will Durant’s The Story of Philosophy (1926), where the Quote/Counterquote archive locates it on page 87, in the chapter summarizing Aristotle’s ethics.
CheckYourFact rated the Aristotle attribution ‘False’, quoting philosopher Richard Kraut that the line is “not Aristotle’s words translated into English… but an accurate and succinct way of conveying what Aristotle says.”
Reference sites now catalog the sentence under Durant’s name, citing The Story of Philosophy as its source.

Public domain

The Story of Philosophy was first published in the United States in 1926, and U.S. works published before 1931 are in the public domain as of 2026 — so Durant’s text, including this sentence, is free to reproduce. The book originally carried a Simon & Schuster copyright, now expired.

Fact-check

The misattribution

This is one of the internet’s most-shared ‘Aristotle’ quotes — and Aristotle did not write it.

Aristotle (384–322 BC) Misattributed

The exact sentence appears in none of Aristotle’s surviving works. It was composed in 1926 by Will Durant as a paraphrase of the Nicomachean Ethics, as documented by CheckYourFact and the Quote/Counterquote archive. Because Aristotle is far better known than Durant, the line drifted to the more famous name.

The idea — that excellence is built by habit — is genuinely Aristotle’s (Nicomachean Ethics, Book II); the quotable sentence is Will Durant’s.

Context

Why it matters

In the Nicomachean Ethics (Book II), Aristotle argues that moral virtue — aretê, often translated ‘excellence’ — is not innate but acquired through habituation: we become just by doing just acts, temperate by doing temperate acts, brave by doing brave acts. He calls virtue a hexis, a settled disposition or ‘habit.’

When Will Durant distilled that argument for general readers in 1926, he coined the epigram that stuck. The compression is so clean that it long ago slipped its author and drifted onto Aristotle himself — a textbook case of a memorable paraphrase outshining both the original text and the writer who actually wrote it.

The thought is Aristotle’s. The sentence is Durant’s.

The real author

Will Durant

1885–1981 · American writer, historian & philosopher; author of The Story of Philosophy

William James Durant (1885–1981) was an American writer and historian who later won a Pulitzer Prize for The Story of Civilization, co-authored with his wife Ariel. His 1926 popularization The Story of Philosophy sold millions of copies and introduced general readers to thinkers from Plato to Dewey. Ironically, his single best-remembered sentence is one the public now hands to the philosopher he was paraphrasing.
