Quotes from Leonard
Ten authenticated sentences, eight dubious or false quotes, and a simple method to no longer confuse a Renaissance manuscript with a motivational poster.
Before quoting
A reliable sentence must leave a mark
Leonardo did not publish a collection of maxims. His words are scattered in notebooks, scientific notes, fables and fragments then assembled by publishers.
A manuscript
The best proof is a codex, folio or passage from the Treatise on Painting linked to a critical edition.
An edition
Richter, MacCurdy and heritage institutions allow you to follow the phrase beyond a citation site.
A translation
A beautiful French sentence is often a modern translation. It should not be presented as the original verbatim.

Ten quotes that can be attributed to Leonardo
The French formulations below are translations. Their vocabulary may vary from one edition to another without rendering the passage false.
"Nothing can be loved or hated without first being known."
Knowledge
Aphorism transmitted by Leonardo's manuscripts and taken up in editions of his writings. Punctuation and choice of verbs vary depending on the translation.
"Experience is never wrong; only your judgments are wrong."
Experience
Leonardo contrasts observation with premature conclusions. The sentence is often abbreviated: the full passage specifies that error comes from expectations that experience does not guarantee.
"Nature never breaks its own laws."
Nature
Brief formula preserved in scientific notes. It summarizes his search for constant causes behind water, flight, optics or anatomy.
"In the rivers the water you touch is the last of that which has passed and the first of that which comes: thus of the present time."
Time
The image of the river combines his observation of water and a meditation on the moment. It is attested, even if the French translations differ slightly.
"Iron rusts for lack of use; stagnant water loses its purity... thus inaction undermines the vigor of the mind."
Action
The viral version often omits development on water and cold. The meaning remains faithful: the mind must be exercised like matter in motion.
"A good painter has two main things to paint: man and the intention of his mind."
Painting
In the Treatise on Painting, Leonardo explains that the visible body must make interior movement perceptible. The second task is, he says, the most difficult.
"Science is the captain, and practice is the soldiers."
Science and practice
This maxim does not disregard practice: it asserts that effective action needs a guiding principle.
"He who, in a discussion, invokes authority does not use his intelligence, but his memory."
Authority
The formula corresponds to his ideal of knowledge verified by experience. Depending on the editions, “discussion” can become “controverse”.
"Poor is the student who does not surpass his master."
Master and student
Maxime consistent with workshop culture: learning is not just about reproducing, but about extending and surpassing.
"Bird would rather die than lose its freedom."
Liberty
The passage belongs to a note about the goldfinch which would bring a plant to its little captives. We must avoid making it a modern declaration of animal rights.

Eight famous quotes not to be attributed to him without reservation
Some are entirely false; others simplify a real idea until its source and meaning disappear.
"Simplicity is the ultimate sophistication."
Not found in notebooks and reference editions. The formula circulated in the 20th century, particularly in design culture, before being late attached to Leonardo.
"Knowing is not enough, you must apply; wanting is not enough, you must act."
The wording comes from Goethe, in The Traveling Years of Wilhelm Meister. Its presence on “Léonard” posters does not change its origin.
"Learning never exhausts the mind."
The English phrase “Learning never exhausts the mind” is ubiquitous, but no reliable reference to a Leonardo folio usually accompanies attribution.
"I was impressed by the urgency to act. Knowing is not enough..."
This version combines several ideas and takes up the false attribution of Goethe's phrase to Leonardo.
"Once you taste flight..."
The romantic text about the man walking with his eyes turned to the sky is often associated with Leonardo, but its common form is not found in his manuscripts.
"Art is never finished, only abandoned."
The idea resembles his practice and a similar formulation is conveyed by Vasari about art, but the exact modern phrase should not be cited as a certain line in his notebooks.
"Painting is poetry that is seen..."
The parallel between painting and poetry belongs to the Treatise. The sentence distributed online, however, mixes several translations and must be linked to the complete passage.
"Details make perfection, and perfection is not a detail."
No stable reference to Leonardo's manuscripts supports this very modern French formulation.
Instructions for use
How to check a quote in five minutes
- Search for the sentence in quotation marks, then without Leonardo's name.
- Request the codex, folio number or chapter of the Treaty.
- Compare at least two editions or translations.
- Check if the phrase appears suddenly in the 20th or 21st century.
- If no primary source is given, write "attributed to Leonardo" rather than "Leonardo said".
Good reflex: a very modern quote, perfectly calibrated for management or design, must inspire more caution than a long, irregular note linked to a concrete problem.

FAQs
Authenticate a quote from Leonardo
How do you know if a quote from Leonardo is authentic?
Look for a reference to a codex, folio, treatise on painting, or scholarly edition like that of Jean Paul Richter or Edward MacCurdy. A shared image without a source is not proof.
Did Leonardo write in Italian or Latin?
He wrote mainly in vernacular Italian, often from right to left, with technical terms and ancient forms. He also used Latin, but mastered it less easily than humanists trained from childhood.
Why are the translations different?
Leonardo's syntax is that of working notes, not always texts prepared for publication. Publishers sometimes reorganize fragments and translators must choose between literality and fluidity.
Is "Simplicity the Supreme Sophistication" by Leonardo?
No: no occurrences are known in his writings. The attribution to Leonardo is late and without documentary reference.
Is "art never finished, only abandoned" authentic?
The exact formula is uncertain. It reflects an idea passed around the creation and corresponds to Leonardo's reputation, but it should not be presented as a certain quote from a notebook.
Can we use the translations of this article?
Yes by presenting them as French translations of passages attributed to Leonardo. For academic work, consult the critical edition and cite the original language with the folio when available.
