The Rulebook Twain Hid in an Insult

On “Fenimore Cooper’s Literary Offenses,” 1895, and the writing rules it still enforces

The manual, and the insult

In 1895 Mark Twain published a book review so brutal that it outlived the books it reviewed. “Fenimore Cooper’s Literary Offenses” takes apart the novels of James Fenimore Cooper, then celebrated as the greatest romancer America had produced, and it is still one of the funniest demolitions in American letters.

What almost nobody remembers is that a set of rules is buried inside the insult. Twain did not sit down to write a style guide. He wrote one anyway.


The charge

Twain opens by keeping score. In two-thirds of a single page of Cooper’s novel Deerslayer, he reports, Cooper “scored 114 offences against literary art out of a possible 115.” Then he lays out the tally. There are nineteen rules governing literary art in the domain of romantic fiction, some say twenty-two, and in Deerslayer Cooper broke eighteen of them.

Eleven of those rules are about storytelling, and they are the ones a reader nods along to. A tale must accomplish something and arrive somewhere. The people in it must be alive, and the reader must be able to tell the living from the corpses. When they talk, the talk must sound like human talk, stay near the subject, and stop when the speaker has nothing more to say.


The little rules

It is the last seven that stop you. Twain calls them the little ones, then sets them down like a checklist:

Twain’s little rules, verbatim

12. Say what he is proposing to say, not merely come near it.

13. Use the right word, not its second cousin.

14. Eschew surplusage.

15. Not omit necessary details.

16. Avoid slovenliness of form.

17. Use good grammar.

18. Employ a simple and straightforward style.

Then the verdict: “Even these seven are coldly and persistently violated in the Deerslayer tale.”


Read it again, with a machine in the room

Say what you propose to say, not merely come near it. Use the right word, not its second cousin. Eschew surplusage. A simple and straightforward style. Twain was aiming at a dead novelist, not at anything that could type. He could not have known that his complaint would land, more than a century later, on a new kind of writer.

The failures he names are, almost one for one, the failures of prose a machine produces when nobody edits it. The approximate word standing in for the exact one. The padding no sentence asked for. The paragraph that wanders off and never quite arrives. Point a language model at a blank page, and a good deal of what comes back has exactly these faults.

Twain even names the mechanism. Cooper, he writes, had a poor ear for words, so “his ear was satisfied with the approximate word.” The result is “a literary flatting and sharping,” a writer who “keeps near the tune, but it is not the tune.” Read a first machine draft and you hear the same thing. It keeps near the meaning. It is not the meaning.

He keeps near the tune, but it is not the tune.


Why we keep the list

So every line here goes through a checker and a review before it goes out. The rules are not new, and they are not ours. Eschew surplusage is exactly what we call compression. Use the right word, not its second cousin, is a ban on the vague and the almost-right. Say what you propose to say, not merely come near it, is the plainest statement of the rule we return to most, which is that if you can just say it, you say it.

Twain wrote the gate in 1895. When we point a machine at his stories, in The Jumping Frog, The Invalid’s Story, and Journalism in Tennessee, and The Stolen White Elephant, we hold the new work to the rules he set for the old, and we want from it the right word, no surplusage, and a plain, straight line.


The savagery is the teaching

It would leave the wrong impression to call the essay a lecture. It is a comedy, and Twain catalogs Cooper’s tricks with open glee. There is the broken twig somebody steps on every time silence is “worth four dollars a minute,” until Twain proposes the whole Leather Stocking series be renamed the Broken Twig Series. There is the band of Indians who wait in a bent sapling to drop onto a passing boat, and then miss it, the chief landing in the stern and knocked silly, his five companions leaping after him one at a time, each falling farther back in the water than the last. There is Chingachgook, whom Twain insists on pronouncing “Chicago.” There are the three rifle balls Cooper claims went into a single hole a hundred yards off, which nobody dug out to check.

None of it is explained. Twain stands over the bad writing and points, and the pointing teaches more than a rule ever could. You learn what surplusage is by watching a man drown five Indians to fill a page. That is the method this project borrows. Read the master, watch what he does, and steal the move.


The last rule

So the meanest review in American literature turns out to be a writing manual with the covers torn off. Its hardest rule is the one a machine breaks first, and the one we keep closest. Use the right word, not its second cousin. Cooper reached for the second cousin every time. So does the machine, on the first try. The work is in catching it.

Twain’s essay is in the public domain, and the lines quoted here are his, untouched. This page is new work made with AI and led by a person. We do not hide the tool, and we do not pretend it ran the show. That honesty is part of the experiment. The whole point is to see the seams.
