The law has a charming habit of behaving as though language becomes precise the moment someone in a robe frowns at it. Words that drift cheerfully in ordinary life are summoned into court, sworn in, interrogated under oath, and expected to produce stable meaning under institutional pressure. When they fail, as they reliably do, the system does not conclude that language may be structurally insufficient for the task. It consults another authority. A dictionary. A drafting manual. A corpus database. A professor, if civilisation has really run out of excuses. Whatever. Any port in a storm. Then it calls the result interpretation, and everyone pretends the word was waiting there all along.
Watch the video below. It is an admirably clean illustration of exactly this.
What you just watched is not merely a curiosity about punctuation and gun laws. It is a diagnostic. And if you have read Chapter Five of A Language Insufficiency Hypothesis, you will recognise the pathology immediately.
The video gives you three cases, each one a new rung on the same ladder of failed repair.
tl;dr? They tend to make it up as they go to serve their power needs.
First, Muscarello v. United States (1998): A man transports a handgun in a locked glove compartment whilst conducting a drug transaction. The statute punishes anyone who ‘uses or carries a firearm’ during such a crime. The question is whether ‘carry’ includes a weapon stored in a vehicle. The Supreme Court reaches for the OED, finds that the earliest documented sense of carry includes conveyance by vehicle, and sends Muscarello to prison, where he eventually dies. Convenient etymology. Regrettable outcome.
The video notes – correctly, I might add (and so do) – that this is an instance of what linguists call the sense-ranking fallacy: assuming that the first definition listed is the primary one, rather than simply the earliest documented. The OED’s ordering is historical, not hierarchical. Why a US court chose the OED is a sign of refinement yet remarkably curious for an American institution.
Second, the Oakhurst Dairy case: Maine truck drivers sue for $10 million over a missing Oxford comma in a statutory overtime exemption. Both sides marshal gerunds, asyndeton, the Chicago Manual of Style, and the Maine legislative drafting manual, which explicitly prohibits the Oxford comma – making the ambiguity, in a sense, officially mandated. The case settles without a definitive ruling. The language did not yield a winner; the lawyers did. The hole wasn’t filled, but their pockets were.
Third, and most instructive, corpus linguistics arrives as the shiny new repair tool. Rather than trusting dictionaries, courts can now search large databases of actual language use to establish ‘ordinary meaning’. Progress. Empiricism. Science, even. And then, almost immediately, the next failure mode surfaces: the frequency fallacy (common usage is not the only permissible usage), corpus skew (many databases over-represent news articles), and search-framing (the ‘sanitation’ / ‘sanitise’ mask mandate case, where including a related but non-synonymous word shaped the results before analysis had even begun). The supposedly empirical tool inherited the user’s prior interpretive frame. Extraordinary.
Follow the sad path of the sad panda: ordinary meaning fails → dictionaries → dictionaries fail → corpus linguistics → corpus linguistics fails → methodological dispute about whether judges should be conducting quasi-scientific research from the bench at all.
And so it goes…
In A Language Insufficiency Hypothesis, Chapter Five argues that law is not a domain that occasionally encounters linguistic difficulty. It is a domain that is constitutively dependent on terms that live in the Contestables zone of the Effectiveness–Complexity Gradient – words like reasonable, fair, cruel, due process – terms indispensable to legal order and perpetually unstable within it. The Gradient’s prediction is blunt: the further a term drifts from stable, concrete reference, the more its meaning must be imposed by authority rather than established by usage.
The video illustrates this at the level of what might seem to be relatively simple terms – carry, distribution, sanitation – words that appear to sit closer to the Invariants end of the scale than to the Contestables. And yet even here, the institutional machinery creaks. If ‘carry’ cannot carry the weight of a single statute without Supreme Court intervention and a man’s death, what prospect does ‘reasonable’ have? Or ‘fair’? Or ‘obscene’?
Potter Stewart, as Chapter Five recounts, admitted in Jacobellis v. Ohio (1964) that he could not define obscenity in the abstract. ‘I know it when I see it‘, he declared. The remark is famous for its candour. It is less often noted that it is also an admission that language had simply given up, and that institutional authority stepped in to do what definition could not. The Court didn’t clarify what obscenity means, but it asserted the power to punish it anyway as it might later decide.
The video’s repair cascade is the same mechanism operating at a more mundane level. Legal interpretation doesn’t overcome linguistic insufficiency. It proceduralises it. Each interpretive tool displaces the instability onto a new surface. Dictionaries relocate the problem from statutory language to lexical authority. Corpus linguistics relocates it from lexical authority to sampling, frequency, and search design. The crack isn’t closed. It’s moved, with considerable administrative ceremony, and the ceremony is called clarity – clear as mud.
The law, in short, functions less as a dictionary than as a sovereign Humpty Dumpty: it decides what words mean when it matters, and enforces those meanings until it decides otherwise. The gavel is doing the work the lexicon cannot.

The lesson here isn’t that dictionaries are useless, corpus linguistics fraudulent, or judges uniquely obtuse. The lesson is structurally worse than that. Each repair works locally and fails architecturally. The law can stabilise meaning long enough to act, and acting is not nothing – Muscarello’s conviction required a determinate reading of ‘carry’, and the system produced one. But it can’t transmute contested language into invariant reference. It can only decide, punish, and maintain the fiction that the word was always waiting there, meaning exactly that.
Textualism – the interpretive philosophy that instructs judges to attend only to the words on the page, nothing more – is, viewed through an LIH lens, an institutionalised form of the Presumption of Effectiveness. It treats language as though it has a singular, determinate meaning recoverable by sufficiently rigorous attention, rather than as a system whose instability is structural rather than incidental. The words on the page are not a fixed source. They are the site of the problem.
If this framing resonates, Chapter Five of A Language Insufficiency Hypothesis develops the full argument – from the Gradient’s account of why legal language is structurally dependent on Contestables, through Potter Stewart’s famous abdication, to the Humpty Dumpty jurisprudence that inevitably follows.

I’ve been getting positive feedback on this book, so I just posted some excerpts from A Language Insufficiency Hypothesis on PhilPapers. I hope this is sufficient to assess whether the book will be of value to you as a reader. Even if you don’t purchase or read the entire book, I am still interested in your feedback here or elsewhere on social media.
Informally, I consider this as Monograph #0, as I hadn’t considered that I’d create a series that follows this concept.

Follows is an inventory of included content:

A recent Substack essay, Jessica Talisman’s Language Is the Bridge, makes a claim that is increasingly common in discussions of artificial intelligence, knowledge graphs, ontologies, metadata, and semantic infrastructure: that language is the bridge between human understanding and machine action. The claim is attractive, and not merely because ‘bridge’ is one of those metaphors that allows technical discourse to cosplay as wisdom literature. It captures something real. AI systems, semantic architectures, ontologies, taxonomies, controlled vocabularies, and knowledge graphs do not run on raw reality. They run on structured representations. Those representations require labels, definitions, mappings, alignments, constraints, and interpretive discipline. In that sense, language work is not decorative. It is infrastructural. But the metaphor is also dangerous.
My extended response to her essay is on Substack.

I read from the Wrong Curve: Free Speech, Pseudo-Invariance, and the Grammar of Liberal Rights. This essay is freely available on Zenodo at https://doi.org/10.5281/zenodo.19636760. This segment is the Abstract and the Introduction.
In this essay, I argue that free speech discourse is structured by a category error whose source lies upstream of speech itself: in the treatment of ‘freedom’ as a stable philosophical primitive when it functions, in practice, as an essentially contested concept operating under a systematically inflated presumption of effectiveness.

tl;dr: I don’t believe in free speech.
We’ve all likely heard that the freedom to swing one’s fist ends at the tip of another’s nose. I can accept this without argument for the purpose of this assertion. Your freedom TO violates my freedom FROM.
The problem is that one’s words don’t stop. In some cases, they continue in the manner of pollution that I don’t want my ear holes to be exposed to this noise. In the social media age, this effect is trebled and molests my eyes. This is especially egregious for misinformation and disinformation, which is to say, much of the internet and beyond.
This impact hasn’t been suitably addressed, so I wrote about it. Here, I read.
I had planned to write a blog post on The Remains of the Day, but I posted it on Substack instead because I changed the scope. I also created this podcast on NotebookLM.

I have just started reading Kazuo Ishiguro’s The Remains of the Day, and I must confess that I can’t read like a normal person.
I made it roughly fifteen pages before the analytical lenses clamped on and refused to retract. Stevens – Ishiguro’s impeccable, heartbreaking narrator – opens with a monologue about what makes a great butler, and I found myself not following the argument so much as watching the scaffolding. Because Stevens isn’t really theorising butlers. He’s performing a world. And the performance is so seamless, so grammatically composed, that it almost disguises itself as description.
Here’s the trick. Stevens treats terms like greatness, dignity, and quality as though they named discoverable features of reality. He doesn’t present them as historically contingent, institution-soaked, liable to buckle under interrogation. He presents them as if the universe itself had ratified them, and he’s merely reporting. It’s the calm, definitional tone of a man who believes he’s describing essences when he is actually curating preferences.
Take butler itself. In ordinary usage, it looks occupationally concrete – a person who does a particular job. But in Stevens’s mouth, it stops being a role descriptor and becomes a bearer of metaphysical vocation. The word accrues civilisational mythology, evaluative freight, quasi-sacred weight, until it no longer refers to a man who answers a door but to a figure who embodies an entire moral cosmology. That is a lot for a job title to carry, and the weight does not come from the world. It comes from the grammar.
Then there is dignity. An interlocutor reasonably suggests that dignity might be something like beauty, a weasel word, like aesthetic, perceptual, taste-bound. Stevens refuses the comparison. Dignity must not sound contingent. It must present itself as something sturdier than preference, almost an objective feature of character, something a person has in the way a table has weight.
And then, naturally, he proceeds to explain it in entirely aesthetic terms: comportment, bearing, restraint, and poise – the look of self-command.
He denies the aesthetic register but then relies on it. His explicit philosophy and his operative language diverge. This isn’t a slip. It’s structural. The term needs to disavow its own supports in order to retain authority. Dignity must deny its kinship with aesthetic discrimination precisely because, without that kinship, it has no flesh.
We do this constantly – take the shakiest words and polish them until they look load-bearing. The more pressure the term is under, the more ceremonially we utter it.

There’s a name for what Stevens is doing, and I’ve spent a perhaps inadvisable amount of time trying to articulate it.
In my own work, A Language Insufficiency Hypothesis, I distinguish between terms that behave differently under pressure. Some are genuinely invariant – they hold stable reference across contexts, and disagreement about them can be resolved by checking. Some are contestable – stable enough for coordination and argument, but insufficiently fixed to secure the same uptake everywhere. And some are fluid – still rhetorically potent, still action-guiding, but drifting across contexts without anyone quite admitting it.
Stevens’s vocabulary sits at the dangerous end of that spectrum. Greatness and dignity are classic contestables, possibly shading into fluids: they retain social force long after referential stability has gone soft. They still feel like they mean something precise. They don’t. And Stevens’ entire identity is organised around treating them as though they do.
This matters because the language isn’t sitting atop an independent self. It’s helping to constitute the self Stevens can intelligibly be. His selfhood is assembled from grammars of rank, service, and propriety. The role vocabulary doesn’t describe a prior person. It builds one.
Stevens admits that his father might belong among the great butlers, despite lacking certain attributes Stevens associates with the newer generation. He notes the gap, then writes it off. The missing qualities belong to a different era; they are secondary, accidental, beside the essential point. His father remains the reference.
But notice what has happened. Stevens is not applying a neutral criterion and then discovering that his father qualifies. He’s adjusting the criterion around the father he already reveres. The supposed standard of greatness turns out to be less a fixed measure than a retrospective act of preservation. Firstly, canonise the figure, then tidy the theory.
The father is doing at least three jobs at once: He’s an exemplar; he’s a stabilising emotional anchor; and he’s a concealed limit-case that proves the category is being bent.
That’s how value-laden language typically works. The abstraction pretends to govern the attachment, but really the attachment is governing the abstraction. Stevens wants the dignity of a rule whilst retaining the comfort of a cherished exception. This isn’t hypocrisy in the simple sense. It’s something more interesting: it’s the ordinary mechanics of human categorisation when the stakes are personal.
And of course, the father isn’t merely a person Stevens admires. He’s the living conduit through which Stevens inherits the whole ontology of service. When Stevens prefers his father as the reference point, he’s anchoring the category in the formative figure through whom the category became intelligible in the first place. The father is part of the installation mechanism.
With the reverent caveat that it may be apocryphal, Stevens recounts a story in which an unidentifiable butler known to his father, confronted by a tiger under a dining room table (the details are gloriously improbable), maintains perfect composure. He doesn’t flinch. He doesn’t break form. He remains, in the deepest sense, a butler.
Whether the story is true barely matters. Its function isn’t evidential but exemplary. It condenses a whole metaphysics of dignity into narrative form. It is a saint’s life for the religion of service.
And that’s the key. For the father – and then for Stevens – dignity is not a detachable opinion. It’s a lived orientation. In the face of the tiger, one doesn’t first deliberate about values and then choose restraint. One already inhabits a world in which restraint is what seriousness looks like. The salience structure is preinstalled. The event is interpreted through it automatically.
The story converts dignity from abstraction into legend. It makes composure appear not merely admirable but real. It turns comportment into ontology. And it authorises imitation through lineage: the son inherits not just a standard but a dramatic image of what the standard looks like when tested.
The possible apocryphal status doesn’t weaken this. If anything, it strengthens it. The father has become less a man than a vessel for the category. The tale smooths over ambiguity and turns a contingent life into an emblem. We’re forever embalming values in stories, then pretending the stories prove the values rather than merely rehearse them.
So Ishiguro’s opening chapter is doing at least four things at once.
That last part is the killer. Stevens’s calm definitional tone is itself evidence of instability. The more pressure the terms are under, the more polished the delivery. He’s performing maintenance whilst pretending to describe an essence.
I’m only one chapter in. I suspect Ishiguro is going to make this hurt.
I published the first version of this essay in February, arguing that the Frege–Geach problem, that three-score-year-old albatross around expressivism’s neck rests on a category error. Analytic philosophers were polite about it in the way that analytic philosophers are polite about things they intend to ignore. I don’t often revise my manuscripts, opting instead to publish a new and improved version, but the meat of this one remained strong and not worth revisiting as much as fortifying.
The trouble was that I’d dissolved the problem without resolving it. Good enough for me. Others were less convinced. Telling people they’ve been asking the wrong question is satisfying but insufficient without a better one. Version 1.1 tidied the prose. Version 1.2 does the actual work.
The new section (§4, if you’ve already read previous versions) introduces recruitable expressions – a broader class of expressions (moral predicates, thick evaluative terms, epistemic and institutional vocabulary) whose full functional load is attenuated under embedding whilst a thinner inferential profile remains available for reasoning. The standard of practical inferential adequacy replaces the demand for semantic identity: what ordinary reasoning requires is not invariance but inferential sufficiency. And the pattern isn’t peculiar to moral language – a noted goal –, which means Frege–Geach stops looking like a special embarrassment for expressivism and starts looking like one symptom of a general feature of how natural language handles multi-functional expressions under logical stress.
The essay is dissolved as a demand for unrestricted semantic invariance. It is resolved insofar as the behaviour it identifies is explained, predicted, and shown to be general.
The revised paper is available here, near the rest of my manuscripts:
Lastly, this essay is built on the foundations of A Language Insufficiency Hypothesis and The Architecture of Encounter, the latter of which wasn’t yet available for the initial publication.
As ever, I welcome the polite ignoring.
I like this bloke. Here, he clarifies Rorty’s perspective on Truth. I am quite in sync with Rorty’s position, perhaps 90-odd per cent.
Allow me to explain.
I have written about truth several times over the years, 1, 2, 3, and more. In earlier posts, I put the point rather bluntly: truth is largely rhetorical. I still think that captured something important, but it now feels incomplete. With the development of my Mediated Encounter Ontology of the World (MEOW) and the Language Insufficiency Hypothesis (LIH), the picture needs tightening.

The first step is to stop pretending that ‘truth’ names a single thing.
Philosopher Bernard Williams helpfully distinguished between thin and thick senses of truth in Truth and Truthfulness. The distinction is simple but instructive.
In its thin sense, truth is almost trivial. Saying ‘it is true that p’ typically adds nothing beyond asserting p. The word ‘true’ functions as a logical convenience: it allows endorsement, disquotation, and generalisation. Philosophically speaking, this version of truth carries very little metaphysical weight. Most arguments about truth, however, are not about this thin sense.
In practice, truth usually appears in a thicker social sense. Here, truth is embedded in practices of inquiry and communication. Communities develop norms around sincerity, accuracy, testimony, and credibility. These norms help stabilise claims so that people can coordinate action and share information.
At this level, truth becomes something like a social achievement. A statement counts as ‘true’ when it can be defended, circulated, reinforced, and relied upon within a shared framework of interpretation. Evidence matters, but so do rhetoric, persuasion, institutional authority, and the distribution of power. This is the sense in which truth is rhetorical, but rhetoric is not sovereign.

Human beings can imagine almost anything about the world, yet the world has a stubborn habit of refusing certain descriptions. Gravity does not yield to persuasion. A bridge designed according to fashionable rhetoric rather than sound engineering will collapse regardless of how compelling its advocates may have been.
This constraint does not disappear in socially constructed domains. Institutions, identities, norms, and laws are historically contingent and rhetorically stabilised, but they remain embedded within material, biological, and ecological conditions. A social fiction can persist for decades or centuries, but eventually it encounters pressures that force revision.
Subjectivity, therefore, doesn’t imply that ‘anything goes’. It simply means that all human knowledge is mediated.
We encounter the world through perception, language, culture, and conceptual frameworks. Every description is produced from a particular standpoint, using particular tools, within particular historical circumstances. Language compresses experience and inevitably loses information along the way. No statement captures reality without distortion. This is the basic insight behind the Language Insufficiency Hypothesis.
At the same time, our descriptions remain answerable to the constraints of the world we inhabit. Some descriptions survive repeated encounters better than others.
In domains where empirical constraint is strong – engineering, physics, medicine – bad descriptions fail quickly. In domains where constraint is indirect – ethics, politics, identity, aesthetics – multiple interpretations may remain viable for long periods. In such cases, rhetoric, institutional authority, and power often function as tie-breakers, stabilising one interpretation over others so that societies can coordinate their activities. These settlements are rarely permanent.
What appears to be truth in one era may dissolve in another. Concepts drift. Institutions evolve. Technologies reshape the landscape of possibility. Claims that once seemed self-evident may later appear parochial or incoherent.
In this sense, many truths in human affairs are best understood as temporally successful settlements under constraint.
Even the most stable arrangements remain vulnerable to change because the conditions that sustain them are constantly shifting. Agents change. Environments change. Expectations change. The very success of a social order often generates the tensions that undermine it. Change, in other words, is the only persistence.
The mistake of traditional realism is to imagine truth as a mirror of reality – an unmediated correspondence between statement and world. The mistake of crude relativism is to imagine that language and power can shape reality without limit. Both positions misunderstand the situation.
We do not possess a final language that captures reality exactly as it is. But neither are we free to describe the world however we please. Truth is not revelation, and it is not mere invention.
It is the provisional stabilisation of claims within mediated encounter, negotiated through language, rhetoric, and institutions, and continually tested against a world that never fully yields to our descriptions. We don’t discover Truth with a capital T. We negotiate survivable descriptions under pressure.
I’ve long had a problem with Truth – or at least the notion of it. It gets way too much credit for doing not much at all. For a long time now, philosophers have agreed on something uncomfortable: Truth isn’t what we once thought it was.
Truth isn’t what we once thought it was
The grand metaphysical picture, where propositions are true because they correspond to mind-independent facts, has steadily eroded. Deflationary accounts have done their work well. Truth no longer looks like a deep property hovering behind language. It looks more like a linguistic device: a way of endorsing claims, generalising across assertions, and managing disagreement. So far, so familiar.
What’s less often asked is what happens after we take deflation seriously. Not halfway. Not politely. All the way.
That question motivates my new paper, Truth After Deflation: Why Truth Resists Stabilisation. The short version is this: once deflationary commitments are fully honoured, the concept of Truth becomes structurally unstable. Not because philosophers are confused, but because the job we keep asking Truth to do can no longer be done with the resources we allow it.
The paper introduces a deliberately unromantic idea: truth exhaustion. Exhaustion doesn’t mean that truth-talk disappears. We still say things are true. We still argue, correct one another, and care about getting things right. Exhaustion means something more specific:
After deflation, there is no metaphysical, explanatory, or adjudicative remainder left for Truth to perform.
Truth remains grammatically indispensable, but philosophically overworked.

Once deflationary constraints are accepted, attempts to “save” Truth fall into a simple two-horn dilemma.
Horn A: Stabilise truth by making it invariant.
You can do this by disquotation, stipulation, procedural norms, or shared observation. The result is stable, but thin. Truth becomes administrative: a device for endorsement, coordination, and semantic ascent. It no longer adjudicates between rival frameworks.
Horn B: Preserve truth as substantive.
You can ask Truth to ground inquiry, settle disputes, explain success, or stand above practices. But now you need criteria. And once criteria enter, so do circularity, regress, or smuggled metaphysics. Truth becomes contestable precisely where it was meant to adjudicate.
Stability costs substance. Substance costs stability. There is no third option waiting in the wings.
To test whether this is merely a theoretical artefact, the paper works through three domains where truth is routinely asked to do serious work:
In each case, the same pattern appears. When truth is stabilised, it collapses into procedure, evidence, or institutional norms. When it is thickened to adjudicate across frameworks, it becomes structurally contestable. This isn’t relativism. It’s a mismatch between function and resources.
Not quite. Quietism tells us to stop asking. Exhaustion explains why the questions keep being asked and why they keep failing. It’s diagnostic, not therapeutic. The persistence of truth-theoretic debate isn’t evidence of hidden depth. It’s evidence of a concept being pushed beyond what it can bear after deflation.
Truth still matters. But not in the way philosophy keeps demanding. Truth works because practices work. It doesn’t ground them. It doesn’t hover above them. It doesn’t adjudicate between them without borrowing authority from elsewhere. Once that’s accepted, a great deal of philosophical anxiety dissolves, and a great deal of philosophical labour can be redirected.
The question is no longer “What is Truth?” It’s “Why did we expect Truth to do that?”
The paper is now archived on Zenodo and will propagate to PhilPapers shortly. It’s long, unapologetically structural, and aimed squarely at readers who already think deflationary truth is right but haven’t followed it to its endpoint.
Read it if you enjoy watching concepts run out of road.
