This is a real sentence from the Meditations, Book 5, section 16 — and this exact English wording is George Long’s translation, first published in 1862. The line is confirmed verbatim in the Long text and matches the Greek, “βάπτεται γὰρ ὑπὸ τῶν φαντασιῶν ἡ ψυχή” (“for the soul is dyed by its impressions”).

Such as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts. Dye it then with a continuous series of such thoughts as these: for instance, that where a man can live, there he can also live well. But he must live in a palace; well then, he can also live well in a palace. Meditations, Book 5 §16

The Greek of the opening clause: “Οἷα ἂν πολλάκις φαντασθῇς, τοιαύτη σοι ἔσται ἡ διάνοια· βάπτεται γὰρ ὑπὸ τῶν φαντασιῶν ἡ ψυχή.” The verb βάπτεται is the dyer’s word — to dip, to steep.

How this was verified

  • The Greek is intact and independently transmitted: Leopold’s 1908 Teubner text of chapter 5.16 reads “βάπτεται γὰρ ὑπὸ τῶν φαντασιῶν ἡ ψυχή” — Perseus Digital Library ↗.
  • The English quoted here is George Long’s. Section 16 of Book 5 in Project Gutenberg’s text of Long’s translation ↗ opens with the sentence word for word.
  • Long’s translation was first published in 1862 by Bell and Daldy, and reprinted for decades afterwards — the printing history is catalogued at The Online Books Page ↗.
  • The popular short form is listed by Wikiquote under Meditations V, 16 ↗, without a translator credited — the wording is in fact Maxwell Staniforth’s (1964), quoted without its first clause, which is why it matches no translation readers can find by searching the full sentence.
Public domain

The Greek original dates to the second century AD and the English wording quoted here is George Long’s translation, first published in 1862 — both are long out of copyright in the United States. Note that this applies to this rendering only: modern translations of the same passage, such as the twentieth- and twenty-first-century versions, are separately protected by their translators’ and publishers’ copyrights.

This reflects the original work, which is public domain. If your exact English wording comes from a specific modern translation, that translation may itself still be under copyright — check the edition you quote.

Fact-check

What goes wrong with this one

The attribution is right, which makes this a rarity among famous Marcus Aurelius quotes. What travels badly is the wording — and, on at least one occasion, the philosopher’s name.

Socrates false credit

An Indian daily ran the line as its “Quote of the Day by Socrates,” presenting it as the Athenian’s and discussing it as such — see The Sunday Guardian ↗. Socrates left no writings at all; the sentence is Marcus’s.

Maxwell Staniforth — the translator nobody credits uncredited translation

“The soul becomes dyed with the colour of its thoughts” is the form quote sites run, and Wikiquote lists it under Book V, 16 ↗ without naming a translator. It is not a loose compression of the passage: it is the back half of Maxwell Staniforth’s 1964 Penguin Classics rendering — “Your mind will be like its habitual thoughts; for the soul becomes dyed with the colour of its thoughts” — circulated with its opening clause lopped off and its translator’s name dropped. Compare the renderings side by side at WIST ↗. A real translation, then, quoted half and credited to nobody — which also means it is the one wording here still under copyright.

The sentence stops too early missing context

Marcus does not leave it as an observation. In Long’s text ↗ the next words are the instruction the aphorism exists to set up: “Dye it then with a continuous series of such thoughts as these.”

Marcus Aurelius wrote it; the wording quoted here is George Long’s 1862 English for Meditations 5.16, confirmed sentence-for-sentence in the Long translation ↗ and against the Greek at Perseus ↗.

Context

Why it mattered

Marcus is not writing self-help here — he is writing a maintenance instruction to himself. The Greek verb is βάπτεται, the word for dipping cloth in a dye-vat: the soul does not have thoughts, it is steeped in them until it takes their colour permanently. And the noun he uses for what does the dyeing is φαντασίαι — the impressions that arrive uninvited, the mental pictures you keep returning to.

That is why the passage does not stop at the famous sentence. The very next words are an order: “Dye it then with a continuous series of such thoughts as these” — and the example he reaches for is bleakly practical, that a man can live well anywhere he can live at all, palace included. The line quoted online as gentle wisdom is, in context, a Roman emperor telling himself to stop marinating in the wrong thoughts.

The soul does not have thoughts. It is dipped in them.

On the translations — and why the popular version is shorter

Long’s “thoughts” is one defensible choice among many for φαντασίαι. Comparative lists of the English renderings show Casaubon (1634) reaching for “fancies, and imaginations,” Haines (Loeb, 1916) for “the soul takes its dye from the thoughts,” Rendall (1898) for “impressions,” and Farquharson (1944) for “repeated imaginations” — see the side-by-side at WIST’s collation of Meditations 5.16 ↗. And then there is Maxwell Staniforth’s 1964 Penguin: “Your mind will be like its habitual thoughts; for the soul becomes dyed with the colour of its thoughts.” That second clause, on its own, is the wording the internet runs — the popular version is shorter because it is Staniforth’s sentence with the first half cut away, not because anyone paraphrased the Greek. Marcus’s point survives all of them; the poetry does not survive equally.

Book 5 is among the parts of the Meditations with an independent medieval paper trail: the Byzantine scholar John Tzetzes, writing around 1150 AD, quotes passages from Books IV and V and attributes them to Marcus, per Wikipedia’s article on the Meditations ↗. The chapter this line comes from is not a modern insertion.

About Marcus Aurelius

Marcus Aurelius

121–180 AD · Roman emperor & Stoic philosopher · reigned 161–180 AD

Marcus Aurelius Antoninus was born at Rome on 26 April 121 AD and ruled as emperor from 161 until his death in 180. He is the rare Roman emperor better remembered for a notebook than for a war: the Meditations, twelve books of private Stoic self-address written in Koine Greek during the years he spent planning campaigns on the frontier. He never meant them to be published — the Greek title is Τὰ εἰς ἑαυτόν, “to himself” — which is exactly why they read like someone arguing with his own worse instincts.
