Butlerian Jihad

This is a primer on the Butlerian Jihad, on what Frank Herbert’s text says about it, and on the career the phrase has had since 2021.

Before going after the machine, find out which of your capacities it was holding and who is holding them now.

tl;dr: “Butlerian Jihad” is defined in the glossary at the back of Frank Herbert’s Dune, published in 1965: a crusade against thinking machines, leaving one commandment, “Thou shalt not make a machine in the likeness of a human mind.” In public use the phrase is a demand for prohibition by law or by force. The glossary entry supports that reading, and the reading stops where the glossary stops. Herbert’s own characters give a second account: people turned their thinking over to machines hoping to be set free, and other people with machines gained power over them. That account leaves a question for the present. Which human capacities and political responsibilities get handed to systems, and who ends up holding them?

Where the term turns up, and where the reading stops

In May 2025 Ross Douthat closed a New York Times interview about a superintelligence forecast with a line he expected his readers to get: “I will see you on the front lines of the Butlerian Jihad soon enough.”¹ Three months later, after six masked people threw paint at a coworking office in southeast Portland during an AI networking event, the papers they left behind called for a “Butlerian Jihad Against AI.”² By May 2026 an Indian daily was running an explainer, prompted by the Butlerian comparisons circulating after an AI warning from Pope Leo XIV.³

Douthat and the flyers assume their readers will recognize the term; the explainer shows how far the phrase has traveled, far enough that a national daily has to spell it out. Its definition sits in the glossary at the back of a science fiction novel from 1965, and nobody in that chain had to have read the novel. The definition travels on its own, as a slogan, and it carries the glossary’s boundary with it. Neo-Luddism is the sibling piece to this one.

Public use has settled on one simple demand: get rid of the machines. Herbert’s glossary entry supports that reading, so nobody using it is misquoting him. The glossary is also where the reading stops. What his characters say about the revolt sits further in, and it puts a habit of mind alongside the machines and names the people who gained control by it.

What Herbert wrote

From the “Terminology of the Imperium,” the glossary appended to Dune:

“JIHAD, BUTLERIAN: (see also Great Revolt) — the crusade against computers, thinking machines, and conscious robots begun in 201 B.G. and concluded in 108 B.G. Its chief commandment remains in the O.C. Bible as ‘Thou shalt not make a machine in the likeness of a human mind.’”⁴

That is ninety-three years, followed by what a second appendix calls two generations of chaos, and the action of Dune takes place some ten thousand years later. Across all six of Herbert’s novels the war itself stays offstage. No battle is described, no machine antagonist is named, no army of robots appears.

The explanation arrives in dialogue instead. After Paul Atreides survives the gom jabbar test, Reverend Mother Gaius Helen Mohiam tells him what the revolt accomplished:

“Once, men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.”

Paul answers with the commandment in its other textual wording, “a man’s mind” in place of “a human mind.” Mohiam places the line and then sets her own sharper version beside it: “Thou shalt not make a machine to counterfeit a human mind.” Then she gives the consequence. “The Great Revolt took away a crutch. It forced human minds to develop. Schools were started to train human talents.”⁵

Those schools are why the Dune universe is staffed with people where a reader would expect computers. Mentats do the calculating, and the standard reading extends this to the Bene Gesserit, trained to read bodies and politics, and to the Spacing Guild’s navigators, who use prescience to pick safe routes through folded space.

The machine-attitude

Sixteen years later, in God Emperor of Dune, Herbert has Leto II restate what was being fought:

“The target of the Jihad was a machine-attitude as much as the machines. Humans had set those machines to usurp our sense of beauty, our necessary selfdom out of which we make living judgments. Naturally, the machines were destroyed.”

And in the same book:

“The Butlerian Jihad tried to rid our universe of machines which simulate the mind of man. […] What is anathema? The motivation to ravage, no matter the instruments.”⁶

Put the passages side by side, and the argument has two halves. One is about capacity. Judgment is something people do, “our necessary selfdom out of which we make living judgments,” and it decays when it is handed over; the crutch in Mohiam’s account is what a delegated faculty becomes. The other half is about power. Mohiam names the winners of the transfer “other men with machines,” who used them to enslave the people who had handed their thinking over. Leto puts the word “anathema” on the motivation to ravage, which stays the same whichever instrument carries it out. Smashing hardware follows as a downstream consequence, and Herbert marks it as such: naturally, the machines were destroyed.

Herbert's revolt takes in the machines, the habit of handing judgment to them, and the people who gained control by it. The hardware is where the habit becomes visible.

Where the name comes from

“Butlerian” points at Samuel Butler and specifically at a letter he published in The Press in Christchurch, New Zealand, on 13 June 1863, under the pseudonym Cellarius. “Darwin among the Machines” applies evolutionary logic to mechanical devices and arrives at a forecast:

“The upshot is simply a question of time, but that the time will come when the machines will hold the real supremacy over the world and its inhabitants is what no person of a truly philosophic mind can for a moment question.”

The letter then names its remedy:

“Our opinion is that war to the death should be instantly proclaimed against them. Every machine of every sort should be destroyed by the well-wisher of his species.”⁷

Butler built the idea out in 1872 into three chapters of Erewhon, where a society acts on the conclusion, destroys its machinery and keeps a few relics in a museum.⁸

Herbert never said where the name came from. No interview, letter or working note has surfaced connecting it to Butler. A French Dune blog that works through the parallel in detail describes the material as a juxtaposition of ideas and terms that suggests a reading of Butler by Herbert more than it proves one and names the absence of direct evidence as a weakness of the comparison. English Wikipedia hedges the same way, crediting the association to critical analysis, and the Dune wiki adds Erewhon as a second candidate, also without a Herbert source.⁹ The reading is close to unanimous in the sources that address it at all, since a coincidence on that scale strains belief, and it stays a reading.

The missing evidence leaves the popular use of the phrase intact. Whoever chose the name, the name leads somewhere. It leads to a man who demanded in print what the phrase demands today and more of it: every machine of every sort destroyed, no exceptions, no quarter. A reading that stops there skips the argument Herbert's own text makes.

The other Butlerian Jihad

In 2002 Brian Herbert and Kevin J. Anderson published Dune: The Butlerian Jihad, the first volume of a prequel trilogy that dramatizes the war Frank Herbert left offstage. It has a villain, an AI system called Omnius. It has an army, the cymeks, humans who moved their minds into machine bodies and set up machine rule. And the revolt has a martyr: Serena Butler, whose murdered child ignites it. The Dune wiki files these books under “Expanded Dune” and records that they contradict the original saga; a large part of the readership treats only the six original novels as canon.¹⁰

The martyr also moves the name. Where “Butlerian” had pointed out of the fiction at a real person outside it, the prequels attach it to a character inside the story, and the word acquires an etymology of the trilogy’s own making.

The two versions share a title and disagree about what the danger was. In the prequels, machines attack and humans fight back until the machines are gone. In Frank Herbert’s novels, humans hand over their judgment, other humans gain the advantage, and the machines are destroyed at the end of that sequence. Of the two accounts, the war story is the one that got a novel-length dramatization.

The career of the term

Almost every serious proposal collected here asks for the same thing: ban the machines or break them.

The first serious contemporary use predates both ChatGPT and the Villeneuve films. Erik Hoel published “We need a Butlerian Jihad against AI” on 30 June 2021, arguing that AI research is immoral while developers cannot demonstrate that their systems are “absolutely not conscious in the way humans are.” The essay closes on Herbert’s commandment.¹¹

The wave arrived in 2023, driven by generative AI. Michael Cuenco used the phrase in Compact in April to argue for an indefinite ban going well beyond the pause others were calling for that spring, “a peaceful, preemptive reformation rather than a violent uprising.” Simon McNeil put the anti-capitalist version a month later, writing that “either the technology must be extinguished or the hands that wield it must be cut off,” and Nicolas D. Villarreal answered the next day, calling that unilateral disarmament for workers. Those two argue about the owners as much as about the equipment, which reaches the power half of Herbert’s argument from the labor side. Megan McArdle, writing in the Washington Post that same May, turned the whole thing into a running joke, reporting that she posted “Butlerian Jihad: Now more than ever” whenever a model learned a new trick.¹²

By 2024 and 2025, the phrase had two homes. One was the fight over art, education and machine-generated filler. Andrew Dana Hudson made the case on Solarshades for importing Herbert’s commandment into the present debate, reported a year later from inside a hard-no movement among writers and artists, and marked the distance to the sibling term in one sentence: “It’s not just more Luddism.” The second home was irony. The Douthat sign-off this piece opens with belongs here; a Spectator column enlists writers as its first recruits, and Defector ran a piece titled “Butlerian Jihad Now,” whose actual argument is that AI companionship is a category error.¹³ Publication clusters around the March 2024 release of Dune: Part Two are easy to document, and one of those pieces points out that the term is never spoken in the films at all. A rise in usage caused by the films is plausible and unmeasured.¹⁴

Alongside those two homes, since August 2025, the phrase has been doing something else as well. The Portland flyers carried the phrase as a heading over an act of property damage, and they cite the prequel trilogy for it. In April 2026, Guillaume Verdon, a co-founder of the accelerationist e/acc tendency, used “Butlerian Jihadist” as an insult, aimed at what he called PauseAI militancy.¹⁵ And butlerianjihad.now hosts an anonymous manifesto from a self-described network of journalists, researchers and activists, which asks for AGI to be banned, rules out violence against persons and declares the machines themselves legitimate targets of direct action.¹⁶

Within twelve months the same phrase carried a Defector column's irony, a heading on a flyer, and an insult thrown by one side of the AI debate at the other.

The official vocabulary is moving through the same territory without touching the term. Wired reported in May 2026 on more than a thousand pages of unpublished DHS, FBI and fusion center documents and describes them as opening a category, “anti-tech violent extremism.” The phrase “Butlerian Jihad” appears nowhere in that reporting; the category is being built next to the sentiment, in language that owes Herbert nothing.¹⁷

The word has split into “badge” and “slur,” the way “Luddite” did over a much longer span. Where the two vocabularies meet, somebody usually says so: the Disjunctions essay on a coming Butlerian Jihad sets the term alongside the revived Luddism, and Brian Merchant, the writer who did most to popularize that revival, discussed the Dune material with Edward Ongweso Jr. in 2024 while keeping it out of his own framing.¹⁸

Part of the charge comes from the word “jihad” itself. Herbert built his universe out of Arabic and Islamic vocabulary, jihad and Mahdi and Fedaykin, which critics read as historical depth or as orientalist borrowing depending on who is writing. The marketing for Villeneuve’s first film changed the register: the trailer announces that “a crusade is coming,” which Al Jazeera read as Christianizing a central concept of the books. The badge and the slur both travel in the untranslated word. None of the uses above mentions that history.¹⁹

One use puts the loss of capacity at the center of its case. butlerianjihad.substack.com, a separate project with no connection to the manifesto site above, publishes a weekly essay, written by Claude, an AI model made by Anthropic and edited by a human, arguing that the risk is atrophy, the ongoing transfer of human capacities to systems. That is the capacity half of Herbert's case, made by the kind of thing the phrase was coined against.²⁰

The Butlerian question

Taken as a demand, the phrase runs into the question of enforcement, and there its users divide the way they have since Butler. His answer in 1863 was war to the death, every machine of every sort, no line drawn anywhere. The manifesto at butlerianjihad.now draws its line around persons, with the machines on the far side of it. The 2023 exchange ran into the same wall from the other side and ended in an argument over who would be disarmed. Whoever asks for the prohibition has to say who would enforce it against whom.

Taken as a diagnosis, the phrase opens an inventory that can be worked on without banning anything. Which judgments are being handed over? The crutch stood in for a capacity, and rebuilding that capacity would take the kind of training Herbert’s schools stand for. And whoever holds the systems the judgments went into gains something by holding them. Mohiam gives the shape of the answer in one sentence about men who turned their thinking over in the hope of being set free. The freedom went to somebody else.

Herbert spent the whole cycle on the bill the commandment runs up: schools, Mentats, navigators, and a training apparatus that his invented history keeps staffed for ten thousand years. The Butlerian question is which capacities are worth that cost.

The demand needs somebody with the power to enforce it. The inventory needs nobody’s permission. Name one judgment you handed to a system this year, then name who owns the result. That is the first step, and it scales up to any organization that made the same handover: who controls the system the judgment now runs on, who gains by controlling it and which part of the responsibility stays with the people who let it go.

Related concepts and further reading

Neo-Luddism is the historical counterpart, and the two terms are not interchangeable: Luddism names a documented, selective fight over the terms of skilled work, while the Butlerian version is the maximalist, science-fiction-coded refusal of machines that imitate human thinking, carrying a spiritual charge the labor history does not have. Reactance and future narratives covers what happens to people who are told their future is already settled, which is the rhetorical weather every one of these arguments takes place in. Exit strategies as collective surrender follows the other half of Mohiam’s sentence, the other men with machines, and asks what a shared future is worth when the people building it hold private insurance against it.

On the sources: Herbert’s glossary entry and the Mohiam dialogue in Dune take five minutes to read together and hold the whole argument; the two Leto II passages in God Emperor of Dune state it outright. Butler’s 1863 letter is a few pages and in the public domain.⁴⁵⁶⁷
