Writing Lessons from Through the Looking-Glass

The first chapter of Through the Looking-Glass contains, disguised as a children’s story, three of the most precise accounts in literature of things writers actually do: reasoning out loud, proposing a fiction to a reader, and losing control of a draft. It also demonstrates a structural principle worth stealing — that you can build an entire imagined world out of a single unverifiable detail. This essay reads the chapter closely for all four.

A world built from a blind spot

Before Alice ever climbs through the mirror, she stands on a chair and inventories what she can see of the room on the other side. It is the same room. That is what makes the scene work: the drawing room in the glass matches her own in every visible particular, “only the things go the other way.” There is one exception, one sliver she cannot verify:

First, there’s the room you can see through the glass — that’s just the same as our drawing room, only the things go the other way. I can see all of it when I get upon a chair — all but the bit behind the fireplace. Oh! I do so wish I could see that bit!

The whole book tumbles out of that blind spot. Not a wardrobe, not a rabbit hole — a patch of an ordinary room, maybe two feet square, that a mirror’s geometry withholds. The structural lesson is direct: you don’t need another world to write about. You need one unverifiable corner of this one, and the discipline to build outward from exactly there.

The kitten’s trial: reasoning out loud

The chapter doesn’t open with the mirror, though. It opens with a verdict:

One thing was certain, that the white kitten had had nothing to do with it:— it was the black kitten’s fault entirely.

One thing was certain — the narrator’s first move is total confidence about an accusation against a kitten. We then get the evidence (the white kitten has an alibi; it was having its face washed), the charges (Alice enumerates them: “Number one: you squeaked twice while Dinah was washing your face this morning”), and even a sentencing framework, since Alice is “saving up all your punishments for Wednesday week.” It is a child’s game and a complete parody of jurisprudence at once, and Carroll never underlines the joke.

Then Alice, mid-monologue, runs the logic on herself:

Suppose they had saved up all my punishments! … What would they do at the end of a year? I should be sent to prison, I suppose, when the day came. Or — let me see — suppose each punishment was to be going without a dinner: then, when the miserable day came, I should have to go without fifty dinners at once! Well, I shouldn’t mind that much! I’d far rather go without them than eat them!

In four sentences addressed to a kitten, she invents the concept of accumulated debt, audits her own account, finds the penalty absurd, and dismisses the whole institution. This is what “thinking out loud” actually looks like on the page: not a rehearsed argument, but reasoning that discovers its destination in transit. It is the working method of the essay form, demonstrated by a child, and it is why the scene rewards study by anyone who writes arguments for a living.

”Let’s pretend”: how fiction gets proposed

The engine of the chapter — of both Alice books — is a two-word phrase Carroll is careful to attribute as a habit:

And here I wish I could tell you half the things Alice used to say, beginning with her favourite phrase ‘Let’s pretend.’

Alice’s sister, “who liked being very exact,” objects that two people can’t pretend to be kings and queens, plural. Alice’s solution — “Well, you can be one of them then, and I’ll be all the rest” — is the founding charter of fiction: one consciousness, all the rest of the parts. Every novelist who ever peopled a town from a single desk operates under exactly this license.

Notice what kind of speech act “let’s pretend” is. It isn’t a lie; a lie hides its fictionality. It is a proposal — an invitation with the fictional frame stated up front, requiring a second party’s consent. When Alice says it to the kitten, the kitten cannot consent, so Alice supplies both sides. The pretend-game with a partner is theater. The pretend-game alone is a draft.

Then the phrase does something technically remarkable. Alice says, “Let’s pretend the glass has got all soft like gauze, so that we can get through. Why, it’s turning into a sort of mist now, I declare!” — and it is. The pretense comes true in the middle of the sentence proposing it. Carroll slides from subjunctive to indicative with no visible seam, and by the next paragraph she is through. I have read the passage repeatedly looking for the exact word where imagination becomes event, and the border cannot be found. That is the craft achievement of the chapter: the transition every fantasy novel labors over, executed inside a single sentence of a girl chattering to a cat.

The law of the unobserved room

Once through, Alice discovers the mirror world’s first rule, and it isn’t about reversal. It’s about attention. The parts of the room visible from outside are “quite common and uninteresting, but all the rest was as different as possible.” The observed portion behaves; the unobserved portion is alive. Pictures whisper. The clock has the face of a little old man and grins at her.

Whatever one makes of the physics, it is at minimum a precise psychology: watched things hold still, and the interesting transformations happen exactly where verification can’t reach. Carroll builds his fantasy entirely out of epistemic gaps, and Alice herself models the method. Her reasoning about the mirror-room fire is worth quoting for its rigor alone:

I want so much to know whether they’ve a fire in the winter: you never can tell, you know, unless our fire smokes, and then smoke comes up in that room too — but that may be only pretence, just to make it look as if they had a fire.

She proposes an observation, identifies its confound, and entertains the hypothesis that the world is faking its data — all before climbing onto the mantelpiece. Readers sometimes call the Alice books “nonsense.” The nonsense is rigorous, and the rigor is the trick.

The King’s pencil: the best account of drafting in print

The scene the chapter is secretly about comes after Alice finds the chessmen walking about the hearth. She is invisible to them. She watches the White King struggle up to the table, lifts him to help — and then, when he takes out an enormous memorandum-book to record his feelings, she does something writers will recognize:

A sudden thought struck her, and she took hold of the end of the pencil, which came some way over his shoulder, and began writing for him.

The King’s reaction:

‘My dear! I really must get a thinner pencil. I can’t manage this one a bit; it writes all manner of things that I don’t intend —’

That is the most accurate account of drafting ever written. Every writer knows the days when the pencil writes all manner of things one doesn’t intend, and we blame the instrument — resolve to get a thinner pencil, a better app, a cleaner desk. Carroll’s joke is that the King is right: an invisible hand really is steering. He is only wrong about what kind. Call it habit, call it the language itself, call it whatever it is that finishes your sentences differently than you began them. The Queen’s verdict on the hijacked memorandum — “That’s not a memorandum of your feelings!” — is the harshest and fairest line of workshop feedback in literature.

And what did Alice write, with the King’s own pencil, in the King’s own book? “The White Knight is sliding down the poker. He balances very badly.” Not her feelings either. A field note: concrete, observed, faintly unkind, and true. As a one-sentence style guide for nonfiction, it has never been improved on.

Mirror-writing: an emblem of rereading

The chapter closes with Alice finding a book whose text runs the wrong way. She puzzles at the mirror-writing until the solution arrives: “it’s a Looking-glass book, of course! And if I hold it up to a glass, the words will all go the right way again.” What the mirror yields is “Jabberwocky” — a poem that, even decoded, only half-surrenders its sense, though Alice comes away certain that “somebody killed something: that’s clear, at any rate.”

Reversed writing that must be re-reversed to be read, and even then only partly understood, is as exact an emblem of rereading as exists. The first pass through any real book gives you the mirror text — shapes you recognize, an order you take on faith. The second pass, years later, is holding it up to the glass of everything that has happened to you since. Some of it snaps into meaning. Some of it stays “brillig,” beautiful and sealed.

Alice’s response is the model: “It seems very pretty, but it’s rather hard to understand!” She doesn’t demand the poem explain itself. She files it away, “full of ideas,” and moves on to see the garden.

Four lessons, then, from one chapter: build from the unverifiable corner, not the invented world; let reasoning find its destination in public; frame fiction as a proposal the reader consents to; and when the pencil writes what you don’t intend, record what you can actually observe. Carroll buried a complete writing course in a children’s book. It takes a second reading to find the syllabus.
