Prose that belongs somewhere, and an instrument for putting it there

A reader is three paragraphs into a document that has given no offense, and then a phrase arrives that they have met too often and always in the same company---a rich tapestry, a pivotal role, a promise to delve---and the reading stops. Nothing false has been said. Something has been heard. The reader turns back through the pages already read and hears them again, and every line that seemed only smooth now carries the grain of the mold that cast it.
The recognition runs backward, and that is its cost. Nothing in the document changed; the reader did, and what was taken back was a credit older and quieter than agreement: the working belief that a person stood behind the prose and belonged to the world it described. A 2024 study of scientific abstracts found certain words, delve chief among them, surging after language models came into wide use in late 2022[^1]. Readers learn the machine's parlance as they learn any other, by its emblems, and having heard one they place the speaker. No prose is unaffiliated. The instrument introduced here begins from that fact; its work is to choose the affiliation.
The credit withdrawn in that third paragraph deserves a name: call it membership warrant, the reader's unreflective inference that the author belongs. Aristotle's Rhetoric holds that credibility of character should arise from the speech itself rather than from what an audience believed beforehand[^2]; membership warrant is that credibility in its plainest form, conferred as a reader hears the forms of a trade or an era used as their users use them. It is extended at reading speed and withdrawn at the same speed, and when it goes it takes the pages already read along with it.
The old test of a Londoner ran on the same principle: a Cockney was a child born within the sound of Bow bells, so that belonging was measured by how far a bronze note carried across the roofs. Prose has its bells. The words of a trade ring to the bounds of their parish, and a reader who hears them knows where the writer was raised. The counting house kept a harder form of it: a true coin dropped on the board rang, a counterfeit fell dull, and ring true is what our speech has kept of that. Synthetic prose is poured in a fine alloy. It still does not ring.
A bronze leaves the chaser's bench bright and uniform, the seams filed down and the channels of the pour cut away, and looks like what it is, a thing made yesterday. Weather would give it a skin in time, green where the rain runs and dark in the hollows where the dust settles, until it seems to have always stood where it stands. Founders do not wait for that. They heat the metal until it will take a stain, brush on a wash---liver of sulfur for browns, ferric nitrate for reds, cupric nitrate for greens---and seal the color under wax. The practice is called patination, and no one who buys a cast bronze believes it stood a century in the rain. They believe it is finished.
The machine is a competent founder. It pours clean and brings the casting out of the investment---the mold broken away once the metal sets---sound and complete, the sprues still standing where the metal ran in. What it will not do unasked is chase the casting or color it. Patina does both, filing off the marks of the pour and laying on the color of a place, and takes its name from the second, which is what a reader sees. What time deposits over decades, patination deposits in an afternoon, and the eye that admires the one is not deceived by the other, since both are true to the bronze.
The instrument chases and colors in one motion. Displacement removes the markers of the parlance the prose is leaving, the machine's first among them; affiliation lays on the markers of the parlance it is joining; neither ranks above the other, since the prose is only moving from one parish to the next. A parlance is any community whose speech a reader can place---a trade, a region, an era, an institution, a stance---and it lays on only what that community already holds: its words and idioms, its habits of construction, its figures and allusions. Patina mints nothing. Its value is that the reader has met these forms before, in other mouths.
Two biases steer the choosing. The first leans toward emblems, the forms a reader at large recognizes, over those only members notice, since the aim is affiliation within the reader's reach rather than a disguise fit for an insider's audit. The second leans toward forms with time in them, measured in the English print record through Google Books Ngram data, kept in a library of files, one to a parlance. The library outranks the model's own sense of what is current, for the good reason that this sense is the thing under correction.
The instrument's strongest device is the figure that carries a subject across to something the reader holds already. Richards's Philosophy of Rhetoric named the parts in 1936---the tenor carried, the vehicle that carries it, and the ground they share[^3]---and patina adds a law: the mapping is never one to one, but the association always is. Readers forgive a thin ground. What they carry over whole is the vehicle's standing and the light it stands in, so that a subject borne by an accepted vehicle arrives already half accepted.
Everything turns on that light, which the instrument calls the cast and fixes before any figure is chosen. The old rhetoric knew it as decorum, the fitness of manner to matter. An exact analogy in the wrong cast carries its subject into a light it should not be received in, however sound its ground, while a marginal one in the right cast does honest work. So no vehicle out of cast is admitted, and where vehicles align the instrument prefers more of them, each a member in the truss that bears the subject over.
Return to the reader three paragraphs in, and let the phrase that arrives there be one they have met in the mouths of founders or of the old rhetoricians, used as those users use it. The reading does not stop. The credit goes out again, forward and back across the pages already read: membership warrant returns the way it left, at reading speed, and brings the whole document with it. Nothing in the argument has changed. The document has only been chased and colored.
A church bell answers all of this at once: founded in bronze and poured in a single heat, its shoulder takes a patina that tells the eye how long it has hung in the tower, while its note tells the ear which parish it belongs to, and who was born within the sound of it. No prose is unaffiliated, and the writer has only ever been choosing between parishes. The machine's is one parish among many, and the one readers now hear soonest. Patina is offered as the means of choosing another, and of hanging the bell where the reader already listens.
