“You cannot teach a man anything; you can only help him to find it within himself” Not Galileo. The wording comes from Edgar Quinet, Ultramontanism; or, The Roman Church and Modern Society, ed. C. Edwards Lester (New York: Gates & Stedman, 1845), p. 62, where Quinet writes in his own prose, unquoted and unsourced, that Galileo's "fundamental maxim" was "that one cannot teach another person the truth, that one can only help him to find it in himself." Nothing Galileo wrote contains it. Traced by Quotle.info.

Quinet’s own prose — no quotation marks, no footnote, no source
I would that some one might undertake to seek out in the confidences which escaped here and there from this great man, in some hidden and brilliant fragments, what was the secret demon of this Socrates of the modern world. For think not that chance alone conducts him in his discoveries. His fundamental maxim, that one cannot teach another person the truth, that one can only help him to find it in himself, which is the foundation of his method, is in itself a whole philosophy; it would suffice to place an abyss between him and the purely sensualist schools.
Transcribed from the 1845 scan. The two sentences above are consecutive paragraphs on the page, run together here. Two things about them are worth noticing. The first is grammatical: his fundamental maxim, that… is a reported proposition, not a reported sentence — Quinet is saying what Galileo believed, and choosing his own English words for it. The second is what stands two sentences earlier: Quinet has just called Galileo “this Socrates of the modern world.” The maxim he then hands him is the Socratic one.
English Wikiquote’s Galileo page ↗ carries the sentence as a photo caption and nowhere else: it is not in the sourced quotations from the Dialogue, Il Saggiatore or the letters, not under “Attributed,” and not under “Misattributed.” Nothing on that page gives it a source.
A contributor to Wikiquote’s talk page for Galileo ↗ posted a trace back to E. Quinet, The Roman Church and Modern Society, ed. and trans. C. Edwards Lester (New York, 1845), p. 62, giving the wording as “One cannot teach another person the truth, … one can only help him to find it in himself.” A talk page is not a source, so we went and read the book.
Page 62 of the 1845 scan ↗ has it exactly there, in Quinet’s own sentence, with no quotation marks and no citation attached — and with Galileo described three lines above as “this Socrates of the modern world.”
Quinet held a chair at the Collège de France from 1842 ↗ and, with Michelet, used it for a running polemic against the Jesuits and Ultramontanism; Wikipedia notes that books bearing exactly those two titles appeared in 1843 and 1844. This 1845 New York volume is the English of the second. We could not obtain the French original, so we cannot say what Quinet’s own words for the maxim were — only that the English sentence in circulation is this translator’s.
Quinet’s book was published in New York in 1845 ↗ and is long out of copyright, as is the anonymous translation printed in it. The sentence at the top of this page is a different matter, and the difference is not only cosmetic: Quinet’s line says one cannot teach another person the truth, where the circulating version says a man cannot be taught anything. Who made that change, and when, we could not establish — so we assert no rights status for the wording as quoted rather than guess one.

Fact-check
Often misattributed
This is the most-quoted thing Galileo never said, and it is not really a fake so much as a category error: a nineteenth-century historian’s summary of what a man believed, promoted into what the man wrote.
The actual source of the English wordingEdgar Quinet, Ultramontanism (New York, 1845), p. 62
Read from the scan ↗: “His fundamental maxim, that one cannot teach another person the truth, that one can only help him to find it in himself…” Quinet is characterising Galileo’s method for readers of a polemic against the Church — he supplies no source, and the sentence has never been in quotation marks until other people put it there.

Whose maxim it actually isSocrates Ancestor, not the author
Not a claim we are making for Quinet — he makes it himself, three lines earlier, when he wonders what was the secret demon of “this Socrates of the modern world” ↗. The doctrine that a teacher can only deliver what the pupil already has is Socratic midwifery, and Quinet lent it to Galileo as a compliment.
✓The sentence is real, the book is real, the page is p. 62 — and the man in it is Edgar Quinet, writing about Galileo in 1845 ↗, not Galileo writing about teaching.
Context
Why it mattered
Quinet took his Paris chair in 1842 and promptly stopped teaching his own subject ↗, turning the lectern into a weapon against the Jesuits and papal authority alongside his friend Michelet. Galileo is the hero of that argument, and the point of the chapter this sentence sits in is that the Church did not merely punish a man, it truncated a philosophy — that the trial forced Galileo to publish the mathematics and bury the thinking.
So the “fundamental maxim” is doing a job. Quinet needs Galileo to have had a method that was about drawing truth out of people rather than handing it down, because that is the exact opposite of the institution he is attacking. The sentence is an argument in the shape of a quotation, which is why it detached so cleanly and why it now hangs in classrooms.
His fundamental maxim, that one cannot teach another person the truth — a reported proposition, not a reported sentence.
Read the full story
What Galileo did leave in writing is not far off in spirit, which is part of why the misattribution sticks. The Dialogue’s Salviati tells Simplicio ↗ that in the natural sciences “a thousand Demostheneses and a thousand Aristotles would be left in the lurch by every mediocre wit who happened to hit upon the truth for himself” — which is an argument about authority, and about the pupil arriving at truth unaided. Quinet had read all of that. He then wrote his own sentence for it, and the quotation books have been handing his sentence back to Galileo ever since.
Two things we could not settle, and would rather say so than paper over. We could not read the French original of Quinet’s book, so we cannot show what he wrote before an unnamed translator turned it into this English; the 1845 New York volume names C. Edwards Lester only as editor ↗. And we could not confirm the intermediate stage — the point at which somebody first put the sentence between quotation marks and Galileo’s name under it. Wikiquote’s talk page ↗ shows a trail being followed backwards; ours ends at p. 62.

Edgar Jean Louis Quinet was born in 1803 and made his name translating and arguing with German philosophy before taking a chair in Paris in 1842. He used it, with his friend Jules Michelet, for a sustained public attack on the Jesuits and on papal authority — the lectures behind Des Jésuites (1843) and L’Ultramontanisme (1844), the second of which reached New York in English in 1845 carrying the sentence on this page. He was driven out of France after Napoleon III’s coup, spent the Second Empire in exile, returned after Sedan, and was elected a deputy to the National Assembly. He died in 1875.
