You have probably heard it in a film. A man in a police interview room, spinning a story about a criminal nobody can prove is real: “The greatest trick the devil ever pulled was convincing the world he didn’t exist.”
It is a brilliant sentence. It is also much older than the film. The earliest close match in print belongs to the French poet Charles Baudelaire, in a short story printed in the Paris newspaper Le Figaro on 7 February 1864 — and Baudelaire did not claim the thought as his own either. Inside his story, the Devil says it, and the Devil is quoting a preacher.
The exact English wording came from the screenwriter Christopher McQuarrie, writing The Usual Suspects in 1995. C.S. Lewis, who often gets the credit too, never wrote this line. He did write something close to it, and more careful, and that part is worth the rest of this page.
The trail back from 1995
Quote Investigator, a research site that traces sayings to their earliest known printings, has walked this one back step by step. The stops are worth seeing, because the sentence changes shape a little every time somebody picks it up.
1836. A Quaker writer named John Wilkinson put the idea plainly in a book called Quakerism Examined: “One of the artifices of Satan is, to induce men to believe that he does not exist.” No flourish, no film music. Same thought.
1856. A pastor named William Ramsey wrote that Satan had so influenced the minds of multitudes “as to make them believe that he does not exist.”
1864. Baudelaire’s story “Le Joueur généreux” — “The Generous Gambler” — runs in Le Figaro. A man meets the Devil in the street, goes down into a glittering underground room, drinks, plays cards, and loses his soul without much fuss at all. Partway through, the Devil admits that only once has it ever feared for its own power. It was the day it heard a preacher, sharper than the rest, call out from a pulpit:
“Mes chers frères, n’oubliez jamais, quand vous entendrez vanter le progrès des lumières, que la plus belle des ruses du diable est de vous persuader qu’il n’existe pas !”
In plain English: my dear brothers, never forget, when you hear people praising the progress of enlightenment, that the finest of the devil’s tricks is to persuade you that he does not exist.
Now look at what just happened. Baudelaire wrote a story. In the story, the Devil quotes a preacher. So the most repeated sentence about the devil in the English language reaches us at three removes — and in the original it is a compliment the Devil pays to a sermon.
One small thing gets lost on the way into English. In Baudelaire’s French the Devil is elle, a feminine pronoun. English translators have always made it “he.”
1918 and 1919. The story arrives in English. Arthur Symons translates it as “the loveliest trick of the Devil is to persuade you that they don’t exist.” Joseph T. Shipley gives us “the cleverest ruse of the Devil is to persuade you he does not exist.”
1948. Whittaker Chambers writes an essay called “The Devil” for LIFE magazine and quotes it as “The Devil’s cleverest wile is to make men believe that he does not exist,” crediting Baudelaire. That is roughly the point where English-speaking readers started carrying the line around with them.
1984. The Los Angeles Times quotes the historian Jeffrey Russell: “The prettiest trick of the devil is to make us believe he doesn’t exist.”
1995. The Usual Suspects opens. Loveliest, cleverest, prettiest — and then greatest trick, which is the one that stuck.
So the film did not steal anything. It sharpened a sentence that had been handed round for well over a century, and found the wording that finally held.
What C.S. Lewis actually wrote
The other name people hang on this quote is C.S. Lewis, and you can see why. Lewis wrote an entire book of letters from one devil to another. If anybody sounds like the author of this sentence, it is him.
But it is not in Lewis. What is in Lewis is better, and it has been sitting in plain sight on the first page of the preface to The Screwtape Letters since 1942:
“There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.”
Count the tricks. The famous line names one: getting you to believe nothing is there. Lewis names two, and says they work equally well.
That difference is bigger than it looks. If the only trick is convincing you the devil does not exist, the cure sounds easy — believe harder, stay alert, and you have beaten it. Lewis shuts that exit. The person who is fascinated, who sees something sinister behind every flat tyre and every piece of bad news, is handled just as neatly as the person who laughs the whole subject off. A materialist and a magician, with the same delight.
The Bible’s own picture is not absence either. It is costume. Paul writes in 2 Corinthians 11:14, “And no marvel; for Satan himself is transformed into an angel of light.” Not gone. Dressed well.
Why the difference is worth knowing
Almost everyone who says this line learned it from the film, and that is a perfectly honest way to learn a sentence. Films are how most good lines travel now. Nobody was badly taught here, and nobody was fooled.
But there is something the film version quietly does. “Convincing the world he didn’t exist” puts the speaker outside the trick. The world was taken in. I was not. It is a line that flatters whoever repeats it, which may be part of why it travels so well.
Baudelaire’s version will not let you stand there. In his story it is the Devil who admires the sermon — and the sermon worked. Somebody said the true thing out loud, in a room full of people, and it landed hard enough to be remembered a century and a half later. That is a far more hopeful sentence than the film’s.
And Lewis’s version turns and looks at the reader twice. Not interested? That is one error. Very interested indeed? That is the other one. There is no comfortable seat anywhere in that paragraph, which is exactly why it is worth more than the poster version.
None of this is an argument about whether the devil exists. That is a different page, and a bigger one. This is only about where a sentence came from, and what it was shaped to say before it got smooth.
If you have run into other lines like this, the pattern is common enough to have a shape. “You don’t have a soul, you are a soul” is another sentence that travels under Lewis’s name and is not his. The “definition of insanity” line is not Einstein’s either. Good sentences drift toward big names the way water runs downhill.
And if you want older, more careful language for this whole subject, the desert monks had a name for the thing that comes at you in the middle of an ordinary afternoon: acedia, the noonday demon.
Where that leaves the line
It is still a great sentence. Knowing it belongs to Baudelaire, by way of a preacher, by way of a screenwriter, does not make it less true. It makes it older and stranger. People have been writing some version of it since at least 1836, which suggests it keeps needing to be said.
Next time you hear it, you will know three versions. The film’s, which is the sharpest. Baudelaire’s, which is the funniest. And Lewis’s, which is the only one that does not let anybody off.

If This Got You Thinking, Pass It On
- “Found out today that ‘the greatest trick the devil ever pulled was convincing the world he didn’t exist’ isn’t from The Usual Suspects. It’s Baudelaire, 1864 — and in the story it’s the Devil quoting a preacher.”
- “I always thought C.S. Lewis wrote ‘the greatest trick the devil ever pulled.’ He didn’t. What he actually wrote is better: there are two errors about devils, not one. Ignoring them, and being obsessed with them. Both work equally well.”
- “Loveliest trick, 1918. Cleverest ruse, 1919. Cleverest wile, 1948. Prettiest trick, 1984. Greatest trick, 1995. One idea, five rewrites, and it goes back to at least 1836.”
Quick Questions, Straight Answers
Who really said “the greatest trick the devil ever pulled was convincing the world he didn’t exist”?
The exact English wording comes from screenwriter Christopher McQuarrie in the 1995 film The Usual Suspects. The idea in print is far older. Charles Baudelaire published a close version in the Paris newspaper Le Figaro on 7 February 1864, and a plainer one appeared in John Wilkinson’s 1836 book Quakerism Examined: “One of the artifices of Satan is, to induce men to believe that he does not exist.” No single author invented it.
Did C.S. Lewis say “the greatest trick the devil ever pulled was convincing the world he didn’t exist”?
There is no evidence C.S. Lewis wrote or said “the greatest trick the devil ever pulled was convincing the world he didn’t exist,” and it does not appear in his published work. What Lewis did write, in the 1942 preface to The Screwtape Letters, is that there are “two equal and opposite errors into which our race can fall about the devils” — disbelieving in their existence, and feeling “an excessive and unhealthy interest” in them — and that both errors suit the devils equally well.
Is “the greatest trick the devil ever pulled” in the Bible?
No. “The greatest trick the devil ever pulled was convincing the world he didn’t exist” is not in the Bible in any wording. The nearest biblical idea is disguise rather than absence. 2 Corinthians 11:14 says, “And no marvel; for Satan himself is transformed into an angel of light.”
What did Baudelaire actually write about the devil’s greatest trick?
In his 1864 story “Le Joueur généreux” (“The Generous Gambler”), Charles Baudelaire has the Devil recall the one time it feared for its own power: hearing a preacher cry out from a pulpit that “la plus belle des ruses du diable est de vous persuader qu’il n’existe pas” — the finest of the devil’s tricks is to persuade you that he does not exist. So the line is spoken by a preacher inside the story, quoted by the Devil, and written down by Baudelaire.
Is the saying “convincing the world he didn’t exist” or “doesn’t exist”?
Both versions circulate, and neither is wrong. The film line is “convincing the world he didn’t exist,” and it is widely repeated as “convincing the world he doesn’t exist,” as “the greatest trick the devil ever played,” and simply as “the devil’s greatest trick.” All of them trace back to the same chain: Baudelaire in 1864, and plainer English versions from the 1830s onward.
