Why does Samuel Butler's Erewhon ban machines?

Erewhon is a satirical novel about a hidden country where many of our habits are turned upside down. Its name is an anagram of "nowhere," and Butler asked readers to say it in three short syllables: Ĕ-rĕ-whŏn. The book appeared in London, anonymously, in the last days of March 1872.

Among its many inversions, one has outlived the rest. The Erewhonians have almost no machines, and they treat a pocket watch as dangerous contraband. Centuries before, a scholar had persuaded them that machines were on a path toward consciousness and would end up ruling humanity, so they destroyed them. Butler gives that scholar's arguments at length in three chapters, "The Book of the Machines."

How the book came to be

The machine chapters began in New Zealand. Butler, who farmed sheep there in the early 1860s, published a letter called "Darwin among the Machines" in the Christchurch Press on 13 June 1863. A second letter on machines followed. Back in England, he reworked the first one in 1865 for a London paper, the Reasoner, as "The Mechanical Creation," and then expanded it again for the novel. The opening chapters of Erewhon, about a journey over a mountain range, draw on the high country he knew in Canterbury.

According to Butler's own account, a friend suggested in 1870 that he join his separate articles into a book, and he wrote it mostly on Sundays. One publisher turned it down in May 1871 as too philosophical to be popular. Another, Trübner, took it early in 1872. Helped by two favorable reviews that April, the first edition sold out in about three weeks.

The story around the machines

The narrator, a young man named Higgs, crosses unexplored mountains and finds Erewhon. He is arrested, and a magistrate is horrified by his watch. He is led into the town museum, where cases hold broken fragments of machinery: pieces of steam engines, a cylinder and piston, a carriage built for iron rails. A case of old clocks and watches makes the point. The magistrate compares the narrator's watch with them, and the narrator, by signs, offers to let it be locked away with the rest.

He learns that the Erewhonians had once been far ahead of Europe in mechanics. Then a professor wrote a book arguing that machines were destined to replace humans. It won the country over. After years of argument, the Erewhonians agreed to destroy every invention less than 271 years old. The figure was a compromise; the book's author had asked for three hundred, and one long dispute was over whether a mangle (a laundry press) used by washerwomen should be spared. It was not. A civil war followed between "machinists" and "anti-machinists," and the anti-machinists won.

The arguments in 'The Book of the Machines'

The fictional author builds his case in steps. Here is the core of it, set beside the one reply the novel records.

The anti-machine argument	The reply
Consciousness once arose from a lifeless planet, so new kinds of mind may yet arise	Machines are not a new species but extensions of the human body
Machines have advanced more in a few centuries than animals in ages	A spade is just a longer arm; a machine is a "supplementary limb"
No one can draw a clear line where consciousness begins; even a plant acts as if it knows its interest	Humans are a "machinate mammal" whose limbs lie about the world
Machines already reproduce through people, as red clover reproduces through the humble bee	Status comes from how many such limbs a person can command

The clover argument is the cleverest. Nobody denies that clover has a reproductive system just because it needs bees to carry its pollen. In the same way, the author asks, why deny that machines reproduce, when people build new machines for them? Humans, in this picture, are part of the machines' reproductive system.

Try it: Read the two columns again and choose one AI tool you have used in 2019, such as a voice assistant or a photo app. Write two sentences describing it as an "extra limb" and two describing it as a new kind of creature. Which description feels more accurate, and why?

Why it matters

Erewhon made Butler's name, and its machine chapters have stayed in print and in debate ever since. In a preface to the second edition, Butler protested that he had not meant to mock Darwin, and hinted that his real target was the misuse of analogy. He later told Darwin the book he had in mind was Joseph Butler's The Analogy of Religion. The chapters can be read as a joke about arguments that go too far, as a serious thought experiment, or as both.

The rest of the novel is just as pointed. In Erewhon, illness is punished as a crime, while fraud and theft are treated with sympathy as moral sickness. The machine chapters fit that pattern: Butler takes a respectable idea of his day, Darwin's theory, and follows it to a place that makes readers uncomfortable.

How does 'The Book of the Machines' compare with today's AI debates?

The two sides in Erewhon map closely onto two views heard in 2019. One treats AI as a tool, an extension of human skill like Butler's spade, which only does what people direct. The other worries that increasingly capable systems might develop goals or abilities their makers do not control. Researchers who work on what they call AI safety take the second worry seriously, while many engineers lean toward the first.

The Erewhonians' choice, to stop and roll back a technology, also has modern echoes on a smaller scale. In February 2019 OpenAI announced its GPT-2 language model but at first released only a smaller version, saying it wanted time to study possible misuse. That is a far cry from smashing every machine under 271 years old, but the question is the same one Butler raised: when should a society slow down an invention it does not yet understand?

Butler's own answer is hard to pin down. The Erewhonians win their war against the machines and pay for it with a ruined, backward country. The novel invites you to take the fear seriously and also to laugh at the cure.
