    The Word for a Private Ache

    The ache is yours. The word for it never could be.

    An essay mindmatterandmeaning.com

    Pick a sensation that feels entirely your own — the particular quality of a headache settling in behind your left eye, right now. It seems like the clearest case there could be of something private. No one else feels it. No one else has access to it. And it seems obvious that you could, if you wanted, give it a private name: call this exact felt quality S, fix the meaning of S by attending to the sensation and mentally christening it, and use S thereafter to refer to that quality whenever it recurs. The headache is yours; surely the word for it could be yours too, in the strongest sense — a word whose meaning you alone set and you alone could check.

    Wittgenstein argued that you could do no such thing. Not that the headache is unreal. Not that you can’t talk about it. But that the strongest version of the private word — meaning fixed by a private ceremony, correctness checked by private memory — collapses into incoherence on inspection.1 The argument is one of the most misunderstood in philosophy, and the misunderstanding matters, because the chapter’s whole account of interiority — its case that the felt inner life is real but not the sealed, self-sufficient private chamber we take it for — leans on getting it right.

    The Argument, Stripped Down

    Strip the scenario to its load-bearing parts. You attend to the sensation and inwardly say “S.” You have performed a private ostensive definition: you have pointed, inwardly, at a felt quality and attached a sign to it. The question is whether anything has thereby been defined — whether a meaning has been fixed.

    To have fixed a meaning is to have set up a distinction between using S correctly and using it wrongly. A word with no possible misuse is not a word; it is a noise. So: next week a sensation recurs and you say “S again.” What makes that application correct or incorrect? In the public case, the answer is ready to hand — the community’s practice, the shared criteria, the other speakers who can check you. In the private case, by stipulation, there is nothing but your own memory and your own present inclination. You apply S because this sensation seems to you the same as the one you christened.

    And here the floor gives way. Your only check on whether the sensation really is the same is the very memory whose reliability is in question. If it seems the same, you call it S; and there is no further fact, no independent standard, against which “seems the same” could be tested. Wittgenstein’s sentence is the one to keep: whatever is going to seem right to me is right. And that only means that here we can’t talk about ‘right.’2 The distinction between being correct and merely seeming correct has quietly evaporated, and with it the distinction between following a rule and merely thinking you are. No rule, no meaning, no language. Only the appearance of one.

    You might want to protest that you can simply recognize the sensation when it returns — that recognition needs no outside warrant, because the felt quality announces its own identity. But recognition is itself a capacity that can go right or wrong, and an inner act that could never misfire cannot mark the line between getting it right and merely feeling sure. To think you are following a rule is not yet to follow one.3

    A short statement of the result: the private word is not a word that happens to be hard to check. It is a word for which the very idea of checking has no purchase — and a sign you cannot misapply is not a sign you have given a meaning.

    What the Argument Does Not Show

    Now the misreading, because it is everywhere and it is tempting. People hear the private-language argument and conclude that Wittgenstein has denied inner experience — that he is some kind of behaviorist for whom the headache is nothing but wincing and aspirin-seeking, the felt quality dismissed as a fiction. On this reading the argument is an attack on the inner life itself, and most readers, sensibly attached to their own headaches, reject it.

    They are right to reject that. But that is not the argument. Wittgenstein nowhere denies that you have a sensation, or that it has a felt character, or that the character is yours in a way no one else’s is. He says something far more specific and far more interesting: that the language in which you describe the sensation — the word “ache,” the word “throbbing,” the word “behind the eye” — is a public language, learned from others, governed by shared criteria, and that its meaning cannot be fixed by your private inner pointing. The inner episode is real. The word for it is borrowed.

    Notice the shape of the move, because it is the same shape the whole book has been tracing. The mistake is not believing in inner experience. The mistake is believing that inner experience could be self-grounding — that a bare private presence could, all by itself, anchor a meaning, certify a judgment, serve as the bedrock on which the rest is built. This is what McDowell, reading the private-language argument in its widest setting, identifies as its real quarry: the seductive picture of the Given, the idea that there are bare presences that could be the ultimate grounds of judgment without owing anything to the public, conceptual, world-involving practices in which we learned to judge at all.4 The headache is not in question. The headache as a self-sufficient inner foundation is.

    Why the Chapter Needs This

    Set the result beside the chapter’s other findings and the picture closes. The inner voice, Vygotsky argued, is internalized social speech — outer become inner.5 The self, we argued, is not a Cartesian core — not a self-standing inner subject of the kind Descartes imagined, complete before it ever met the world — but a constitutive achievement conducted in a borrowed vocabulary. The private-language argument supplies the missing structural reason these are not three separate observations but one. The vocabulary of inner life had to come from outside, because there is no other place it could have come from. A meaning cannot bootstrap itself from a private act of attention. The criteria that make “ache” mean ache live in the practice of a community, not in the privacy of a skull.

    This is why interiority is an illusion in the precise sense the chapter intends, and not in the crude sense the misreading fears. The felt life is real, vivid, and particular to you. What is illusory is its self-sufficiency — the sense that the inner is the primary thing, the secure foundation, the place where meaning gets its first grip before reaching out to the world. Run the private-language argument and the order reverses. The reaching-out comes first. The public practice comes first. The inner vocabulary in which you describe your most private ache is itself an inheritance from the outer world, on loan, and answerable to a court you did not convene.

    The ache is yours. The word for it never was.

    Notes

    1. Ludwig Wittgenstein, Philosophical Investigations, trans. G. E. M. Anscombe (Oxford: Blackwell, 1953), §§243–271 for the core of the so-called private-language argument, with the sensation-diary thought experiment (“S“) at §258. The label “private language argument” is not Wittgenstein’s and is somewhat misleading: there is no single deductive argument but a sequence of connected considerations against a particular philosophical picture. I reconstruct the central thread rather than the whole texture. On whether §243–271 constitute one argument or a family of them, see Saul Kripke, Wittgenstein on Rules and Private Language (Cambridge, MA: Harvard University Press, 1982), and the dissent in P. M. S. Hacker, Wittgenstein: Meaning and Mind (Oxford: Blackwell, 1990). ↩
    2. Wittgenstein, Investigations, §258: “One would like to say: whatever is going to seem right to me is right. And that only means that here we can’t talk about ‘right.’” The sentence is the hinge of the whole passage. It does not deny that the diarist has experiences; it denies that the diarist’s bare say-so could constitute a criterion of correct application, and so denies that a meaning has been fixed. The diarist proposes to “concentrate my attention” on the sensation and so “impress on myself the connexion between the sign and the sensation” (§258) — and it is precisely this private ostensive ceremony that Wittgenstein argues cannot do the work of fixing a use. ↩
    3. A natural objection: surely I can simply recognize the recurring sensation, and recognition needs no external check — the felt quality announces its own identity. Wittgenstein’s reply is that recognition is itself an exercise of a capacity that can go right or wrong, and an inner episode that cannot misfire cannot underwrite the distinction between recognizing and merely seeming to recognize; “to think one is obeying a rule is not to obey a rule” (§202). The point is sharpened at §293, the “beetle in the box”: if the word for the sensation got its meaning only from a private object each of us inspects in isolation, “the thing in the box has no place in the language-game at all; not even as a something: for the box might even be empty.” The sensation is not thereby eliminated; rather, its public word does not get its meaning from a private act of inner pointing. For a representationalist gloss compatible with the position taken here — that the felt character is the world-directed content of the state, not a private inner object the word labels — see Michael Tye, Consciousness, Color, and Content (Cambridge, MA: MIT Press, 2000), ch. 1. ↩
    4. The reading of the private-language argument as an application of a more general rejection of the Myth of the Given is John McDowell’s, Mind and World, 2nd ed. (Cambridge, MA: Harvard University Press, 1996), Lecture I, esp. pp. 18–19, where the “apparently compulsory way of thinking” that posits “bare presences that are the ultimate grounds of judgements” is named as “Wittgenstein’s target in the so-called Private Language Argument,” and McDowell proposes to “understand that polemic as applying a general rejection of the [Myth of the] Given.” The connection to Wilfrid Sellars’s critique (Empiricism and the Philosophy of Mind, 1956) is explicit in McDowell and worth pursuing for readers who want the epistemological version of the same point; the wider aim is to refuse what McDowell calls “bald naturalism,” not to deny that the rational is part of nature. ↩
    5. See “The Origins of Inner Speech” (Ch. 7 §I), and L. S. Vygotsky, Thought and Language, rev. ed., trans. and ed. Alex Kozulin (Cambridge, MA: MIT Press, 1986), for the thesis that inner speech develops by the internalization of egocentric, originally social speech; cf. Inner Speech, Stanford Encyclopedia of Philosophy, on Vygotsky’s claim that inner speech “does not change in its fundamental nature” but remains a kind of actual, socially derived speech. Saul Kripke’s influential reconstruction in Wittgenstein on Rules and Private Language (Cambridge, MA: Harvard University Press, 1982) frames the argument around rule-following and the sceptical paradox rather than sensation specifically; I have followed the more orthodox sensation-centred reading here because it bears more directly on the chapter’s concern with the vocabulary of inner states, but Kripke’s version reaches the same destination — that correctness conditions require a community — by the rule-following road. ↩

    The Problem of Other Minds

    Other minds aren’t hidden behind faces. They show in them.

    An essay mindmatterandmeaning.com

    Sit across from someone you have known a long time and ask yourself, honestly, what you know about them. You know their face — not just the geometry but the way it shifts when they’re thinking, the small slackening when they’re tired, the half-smile that arrives a fraction of a second before the joke. You know how they walk into a room. You know what they’re like when something has gone wrong before they’ve said anything has gone wrong. You know roughly what they would say about most things, and you know with reasonable accuracy when you would be surprised.

    The philosopher then asks: but how do you know any of this? You see only the surface. You hear only the words. The inner life — the experience of being them, the felt texture of their day, the what-it-is-like of looking out from behind those eyes — sits sealed inside a place you cannot enter. Whatever you have, you have inferred from behavior. And the inference, the philosopher continues, depends on a single sample: yourself. You behave thus-and-so when you are sad, the other person is behaving thus-and-so, therefore they are probably sad. This is the argument from analogy, and it has been a load-bearing element of modern epistemology since Mill.1

    The argument is bad. It is one of the most cheerfully bad arguments in the canon — and I say this with genuine affection for the tradition that has spent four hundred years refining it — and the reason it has survived tells you something about the picture it presupposes. Here is the short version, before we slow down: the argument from analogy does not discover a gap and then heroically bridge it. It builds the gap, hands you the bridge, and bills you for both. The labor it performs is labor it manufactured — less epistemology than a contractor who cracks your foundation to sell you the repair.

    Take its structure seriously for a moment. The argument from analogy says: I know my own case directly; I observe others’ behavior; I infer their mental states by extending my own case to theirs. The first premise asks us to believe that introspective access to one’s own mental life is straightforwardly reliable — that you and you alone get the first-person facts without mediation, and everyone else is at least one inferential step away. The second premise treats behavior as the surface evidence from which inner states must be reconstructed. The third extends the resulting picture by analogy from the one sample where the inferential gap can be closed (one’s own case) to all the cases where it cannot.

    Every step assumes the inner theater.2

    This is worth dwelling on. The inner theater — the picture this book has been dismantling for twelve chapters — is the picture on which mental states are inner items, accessible directly only to their owner, contingently connected to publicly observable behavior. On that picture, the problem of other minds has the precise shape the argument from analogy gives it: the inner is private, the outer is public, and we need a bridge. Strip out the picture and the problem reorganizes itself completely.

    What goes first is the premise of privileged inner access. Chapters 2 through 4 argued that introspection does not deliver inner objects — it delivers the world as represented. When I attend to my fear of the dog, I find the dog. When I attend to my taste for the coffee, I find the coffee. Introspective reports are not transcriptions of inner items; they are reports made from a particular embodied position about how the world is going for the reporter. They can be wrong; they can be biased; they are bounded by the conceptual vocabulary the reporter possesses; and crucially, they have no privileged epistemic status over and above their distinctive subject matter. I have unique access to my situation, the way every embodied creature has unique access to its situation, but that uniqueness is not the metaphysical privilege the inner-theater picture requires.3

    What goes second is the conception of behavior as a surface. Behavior is not the outer rind of an inner pulp. When my friend leans forward as I describe my mother’s illness and his face does that particular thing it does — eyes slightly narrowing, mouth softening at the corners — I do not see behavior plus an inference to concern. I see concern. The concern is in the leaning, the narrowing, the softening, the particular silence that follows. Concern is the kind of thing that happens as an embodied engagement with another person’s situation, and seeing it does not require me to construct an inner mental state from sensory data, any more than seeing a tree requires me to construct an inner tree from photons. Wittgenstein puts the point as sharply as anyone: “We see emotion. — As opposed to what? — We do not see facial contortions and make inferences from them (like a doctor framing a diagnosis) to joy, grief, boredom. We describe a face immediately as sad, radiant, bored, even when we are unable to give any other description of the features.”4

    What goes third is the entire bridge-building project. The argument from analogy is in the business of getting us from inside to outside; once you stop accepting the picture on which that work needs doing, the argument has no work to do. This is not a refutation in the way a counterexample refutes a generalization. It is a diagnosis: the argument was never tracking a real epistemic problem, but the consequences of an antecedent metaphysical commitment we had no good reason to make. The inner theater opens the gap; the argument from analogy claims, badly, to close it; neither performance is necessary once we notice that the gap was always a stage set.

    Two clarifications.

    First: none of this denies that other people have inner lives. Of course they do. What it denies is that “inner life” names a sealed compartment one approaches only by inference. The inner life of another person is the way they engage with a shared world — what they notice, what they want, what they recoil from, what they remember, what they expect. All of that shows up in their engagement: in the face across the table, in the choices they make, in the things they say and the things they pointedly do not. The inner-ness here is not a matter of location — “inside” the skull as opposed to “outside” — but of perspective: their engagements are theirs, lived from their position, undergone in the first person. The first-person character is real; it is not therefore behind a wall.

    Second: none of this denies that we can be wrong about other people. We are wrong about other people all the time. Sometimes spectacularly. The diagnosis is not a confidence-trick about how easy other minds are; it is an account of what the situation actually looks like — one in which we encounter other engaged creatures in a world we share, and read their engagements with varying accuracy, with biases we don’t always notice. The fallibility is real. What’s not real is the metaphysical chasm the inner-theater picture put between us.

    Here a sharp objection arrives, and it deserves a real answer rather than a wave. The pretence objection: if seeing concern in a face just is seeing concern, then how do you account for the actor, the con artist, the friend who has learned to compose his features over years of not wanting to worry you? People feign emotions they do not have and conceal emotions they do. If that is possible — and obviously it is — then what you see in the face cannot simply be the emotion; there must be an inner state, separable from its outward sign, that the sign sometimes tracks and sometimes fakes. Bridge back, the objector concludes; the gap was real after all.

    It was not. Grant everything the objection observes: people feign, conceal, and mislead, and we are sometimes taken in. None of that requires a sealed inner item. It requires only that the criteria by which we read a face are defeasible — that what ordinarily and rightly counts as seeing concern can, in special circumstances, be overridden by further facts about the situation.5 A defeasible ground is still a ground. The actor’s grief does not show that I never see grief; it shows that grief can be simulated, and that when I learn this, the further fact — the stage, the script — defeats my reading. Defeat is not derivation. The inner-theater picture needs the inner state to be what my evidence reaches toward across a gap; defeasibility needs only that my reading of the situation can be corrected by more of the situation. We catch the con artist not by peering behind his eyes but by noticing the tell, the thing that does not fit the rest of his engagement with the world. Pretence is parasitic on the ordinary case in which expression and emotion run together; it could not get started if the face were not, in the normal run of things, where the emotion shows.

    Once the chasm goes, the relevant question changes from how can I ever know what’s behind those eyes? to how well am I attending to what’s right in front of me? The second question is harder than the first, in one sense: it asks for a skill rather than a proof. It is also vastly more answerable. You can get better at attending. You can pay closer attention to the actual person across the table. You can notice when your default interpretive frame has been doing the work for you. You can ask. The other person can tell you.

    What you cannot do — and what the inner-theater picture has been telling us for three hundred years we ought to be able to do — is stand somewhere apart from the world and the people in it and verify, from outside the relationship, that there really is someone home behind the face. That demand was always strange. We do not stand apart from the world; we stand in it, with these people in it. To ask for an external guarantee that they are minded is to ask for a perspective no embodied creature has ever occupied. The bat does not know its mate from a third-personal viewpoint either, and the bats do fine.

    This shifts where the philosophical work needs to be done. The interesting questions about other minds turn out not to be how do I know they have any? — that one dissolves with the picture that generated it — but questions about the conditions under which inter-creaturely attunement breaks down: the failures of attention that produce real misunderstanding, the cases where the engagement we share is bounded by language or cognitive style or trauma or species. Those are real questions, and they have their answers where all real questions about other minds always had them: in the lived practice of paying attention to other people. Philosophy can help in one modest way. It can clear away the picture that suggested the work was impossible.

    The face across the table is the most ordinary fact in the world. The miracle, if there is one, is that we ever managed to convince ourselves it wasn’t.

    Notes

    1. John Stuart Mill, An Examination of Sir William Hamilton’s Philosophy (London: Longman, 1865), ch. 12. Mill’s formulation — known thereafter as the argument from analogy — works from the asymmetry between my access to my own mental states (allegedly direct) and my access to others’ mental states (allegedly inferential), and bridges the gap by inductive extension from the one case where the inference is supposedly grounded to all the others. The argument has been criticized continuously since Wittgenstein, but it remains the default starting point in introductory philosophy texts because it has the virtue of making the alleged problem look like a tractable epistemic puzzle. Anita Avramides, Other Minds (London: Routledge, 2001), Parts I–II, provides the canonical contemporary survey of the argument’s history and the case against it; the present essay’s diagnosis follows Avramides’ broadly Wittgensteinian-McDowellian line. ↩
    2. The dependence of the argument from analogy on the inner-theater picture is the load-bearing claim of the present essay, and it is not an idiosyncratic one. P.M.S. Hacker, Wittgenstein: Meaning and Mind (Oxford: Blackwell, 1990), Part I, develops the case at book length; the structural point is that the argument requires three commitments — privileged inner access, behavior as outer sign, and a one-case base for analogical extension — each of which is independently implicated in the Cartesian picture this book has been dismantling. Strip any one commitment and the argument loses its premises. Strip all three and the alleged problem ceases to look like a problem at all. The diagnosis aligns with the route John McDowell takes in “Criteria, Defeasibility, and Knowledge,” Proceedings of the British Academy 68 (1982): 455–479, in which McDowell argues that criteria for psychological attributions are defeasible-but-not-derivative — they are the kind of ground for ascription that does not need to be cashed out in non-psychological terms. ↩
    3. The claim that introspective reports do not have the kind of privileged status the inner-theater picture requires is developed at length in Chapters 2 and 4, and connects to Tim Crane’s “Introspection, Intentionality, and the Transparency of Experience,” Philosophical Topics 28 (2000): 49–67. Crane’s point — that introspection terminates in the world rather than in inner objects — applies as cleanly to introspection of one’s own mental life as it does to introspection of perceptual experience: when I attend to my own fear, I find the threat; when I attend to my own joy, I find the source. The “privileged access” the inner-theater picture promises is therefore privileged access to something that turns out not to be a separate inner item at all. For a sympathetic but critical reading from the phenomenological tradition, see Dan Zahavi, “Beyond Empathy: Phenomenological Approaches to Intersubjectivity,” Journal of Consciousness Studies 8 (2001): 151–167. ↩
    4. Ludwig Wittgenstein, Remarks on the Philosophy of Psychology, vol. 2, trans. C.G. Luckhardt and M.A.E. Aue (Oxford: Blackwell, 1980), §570. The “we see emotion” remark distills decades of Wittgensteinian work on the relation between psychological concepts and the publicly available criteria that ground them. The position is not behaviorist — Wittgenstein is not claiming that emotion just is facial contortion, only that recognizing emotion in a face does not proceed by inference from contortion to inner item — but it is anti-inferentialist about the epistemology of other minds. Avramides (2001), chs. 4–5, traces the development of this position through Strawson, Hacker, and McDowell. For the contemporary debate over how much of the position survives the move from the Investigations to neuroscientifically informed accounts of social cognition, see Vasudevi Reddy, How Infants Know Minds (Cambridge, MA: Harvard University Press, 2008), and Shaun Gallagher and Dan Zahavi, The Phenomenological Mind, 2nd ed. (London: Routledge, 2012), chs. 8–9. The book sits closer to the Wittgensteinian deflation than to the phenomenological richness, but neither tradition reads other-minds skepticism as a real problem in need of an epistemological solution; both treat the alleged problem as an artifact of a misleading picture of the inner. ↩
    5. The defeasibility reply is McDowell’s, “Criteria, Defeasibility, and Knowledge” (1982), 455–479: a criterion can be a non-inferential ground for a psychological ascription while remaining defeasible by further features of the circumstance, and defeasibility does not collapse the criterion into mere evidence for a logically independent inner state. The point generalizes the direct-perception literature’s standard handling of pretence. Dan Zahavi, “Empathy and Direct Social Perception,” Review of Philosophy and Psychology 2 (2011): 541–558, concedes that recognizing an expressed emotion frequently requires contextual cues — disgust and contempt, e.g., can be hard to discriminate from the face alone — without conceding that the emotion is therefore an inferred inner item rather than something expressively present; the same move handles the actor and the dissembler. See also Shaun Gallagher and Matthew Bower, “Making Enactivism Even More Embodied,” Avant 5, no. 2 (2014): 232–247, on the social and contextual constraints on the direct perception of emotion. The deeper structural point is that deception presupposes the ordinary case rather than undermining it: a counterfeit is possible only where there is genuine currency to counterfeit, so the very intelligibility of feigned grief depends on grief’s normally showing in the face. ↩

    The Origins of Inner Speech

    The inner voice isn’t where thought begins — it’s speech turned inward.

    An essay mindmatterandmeaning.com

    Right now, as you read this, something happens that probably feels like the most private thing in the world. The words on the page get pulled into your head and they sound — silently — in something you would call your own voice. If I stop a sentence mid-thought, like this one — you finish it. The completion arrives in that same inner voice. You can shout in it without moving. You can argue with it. People who have lost their hearing late in life often report that the voice continues, sometimes even with the accent they used to have.[1] Whatever else this thing is, it feels like the deepest interior we have. A private room with the door shut. The last place where the world doesn’t get in.

    This essay is about why that picture is almost exactly upside down.

    The bad picture goes like this. There is an outside world, full of public language. People talk to each other. There is also an inside, where each of us has an inner voice — a kind of personal narrator who comments on what we see, rehearses what we’ll say, and works problems out under the breath of the soul. The outer language is social, learned, full of conventions. The inner voice is mine — first-person, immediate, the one thing I have that no one else can hear. On this picture, public speech is the noisy externalization of an already-private inner monologue. The thoughts come first, in the head; the words come later, when the thoughts need company.

    This picture comes naturally. It has also done more than almost any other to lock the Cartesian theater into modern philosophy of mind. Once you accept that the inner voice is the thing, you have already conceded that there exists an interior space, with its own contents, accessible only to its owner. The mug on the table starts to recede. The outside world becomes a stage that your real life merely watches.

    Here is the alternative.

    The inner voice is not a private soliloquy that we sometimes externalize. It runs the other direction. Public speech came first — historically in the species and developmentally in each child — and the inner voice consists of that public activity turned inward. What you experience as silent thinking is, very largely, silent speaking: the same activity, with the same meanings, drawn from the same shared language, but with the motor signals turned down so far that nobody else can hear it. The voice in your head has accents because the voice out of your mouth used to. It uses words you learned from other people because all the words you have, you learned from other people. There is no separate inner lexicon. There is only the one lexicon — public, shared, social — being used in two different modes.

    Once you see this, several long-running puzzles relax their grip.

    Take the question of meaning. If the inner voice were a private soliloquy in a private language, then the meanings of its words would have to be fixed somewhere inside the head, by the speaker’s own lights, with no public check. This is what Wittgenstein was attacking when he sketched the famous case of someone trying to give a private name to a private sensation: there is no way to tell whether the next use of the word follows the rule or breaks it, because there is no public criterion of correct use.[2] The argument generalizes. Meaning never gets fixed by what goes on inside a single skull. It gets fixed in the social practices where words have uses people can correct, share, and inherit. The inner voice borrows those meanings from outside. It does not generate them.

    That conclusion sounds counterintuitive only until you ask the obvious question: where would the inner voice get its meanings from, otherwise? It is not as though the language module in your head wakes up one morning with semantics pre-installed. You learned every word you have. You learned them from speakers around you, in contexts where their uses could be corrected. When that public competence later runs silently in your head, it does not shed its public character. It is still the same competence, drawing on the same word-uses, anchored in the same shared world.

    This is also, incidentally, why the inner voice is not the private chamber the bad picture says it is. It is the public voice gone quiet. Your phenomenology bears this out: when you “speak to yourself” you are not having direct contact with raw meaning. You are running through words — words with accents, with grammar, with the cadence of speech.[3] You can describe your inner monologue, transcribe it, slow it down, translate it. None of that would be possible if it were not made of the same stuff as the speech you exchange with other people.

    A useful diagnostic question follows from this. When you find yourself reaching for the inner voice as evidence of some essentially private inner life, ask: would my best guess about what I am thinking really be wrong if I just said it out loud? Almost always, the answer is no. Saying it out loud is what the inner voice would have been, before we learned to turn the volume off.

    This brings us to what we owe Sellars and a long tradition after him. Sellars’s Jonesean myth in “Empiricism and the Philosophy of Mind” posits inner episodes — what we call thoughts — as theoretically modelled on overt verbal utterances rather than directly observed.[4] Tim Crane and Katalin Farkas, working in this lineage, gloss the picture vividly: thoughts are “inner episodes, called ‘thoughts,’ which are conceived on the model of overt verbal utterances, but happen silently in the head.”[5] They treat the inner stream less as a private screening and more as something we model on the basis of our public commerce with each other. The order of explanation runs from public to private, not the other way. We learn what thinking is by learning to talk; then we learn to call the silent version of that activity “thinking.”

    Two further consequences fall out.

    The first concerns AI. If the inner voice is internalized public speech, then producing fluent inner-voice-like outputs — sentences that sound like thinking — is not, by itself, evidence of an inner life behind the sentences. A large language model can produce streams of fluent prose without any of the social, embodied history that gave human speech its meanings in the first place. The model has the surface of inner speech and none of its provenance.[6] The temptation to see understanding behind its outputs comes precisely from the inverted picture I started with: we assume the words must be coming from an interior, because that’s where our own words seem to come from. They aren’t. Our own words come from a long history of public language that ours simply continues.

    The second consequence concerns ourselves. If the inner voice is public speech gone silent, then the most private-feeling activity we have is, at its root, a social inheritance. You think with words you did not invent, in a language you did not design, using meanings calibrated by a community you mostly never met. The Cartesian sense that thinking is yours alone survives only because we forget where the equipment came from. Strip away the borrowed vocabulary and grammar and there would be very little left in the inner room. There would barely be an inner room.

    Now an obvious objection. Surely, the objector says, there is more to thinking than silent speech. Mathematicians solve problems without verbalizing them. Musicians compose without inner narration. Animals without language clearly think. The claim that thinking just is internalized public speech overreaches.

    Take this seriously, because it is mostly right. The claim worth defending is not that every act of cognition consists in inner monologue. Pre-linguistic infants think; non-human animals think; expert performance often runs faster than any inner narrator could keep up with. The claim is narrower and survives: the experience of thinking-in-words — the inner voice, the one that feels like the inmost private chamber — is best understood as internalized public speech. There is non-verbal cognition, certainly, but it is not what feels private. It is what runs below the level of phenomenology. The phenomenologically vivid voice in your head, the one this essay is mostly about, is the silent residue of conversations you have had and conversations you could have. That narrower claim is what the picture I am offering needs, and it is what survives the objection.[7]

    So the inner voice is not nothing. It runs as a real, structured activity, with phenomenal presence. It also does not constitute a private chamber, does not consist of a separate language, and does not anchor the place where meaning gets started. It consists of public speech, well-rehearsed and turned inward — quiet enough that no one else hears, audible enough that you do. The room you thought was private always had the door open. You just never noticed the draft.

    Footnotes

    [1] The persistence of late-deafened speakers’ inner voice in their pre-deafness accent is reported anecdotally and in clinical literature on inner speech across hearing loss; for a careful treatment of inner-speech phenomenology more generally see Hurlburt, Heavey & Kelsey (2013), “Toward a Phenomenology of Inner Speaking,” Consciousness and Cognition 22(4): 1477–1494, whose Descriptive Experience Sampling reveals large individual differences in the frequency and texture of inner speaking. The picture I draw on these data — that inner speech inherits its phenomenal character from prior outer speech rather than the other way round — runs slightly ahead of Hurlburt et al.’s own conclusions and is the present author’s reading, consistent with their findings rather than directly argued by them.

    [2] Philosophical Investigations §§243–315, especially §258. The thrust is not the often-misread “no one could secretly invent a private code,” but rather that the very notion of following a rule requires the possibility of public correction. Without that, there is no fact of the matter about whether the next application of a term agrees with the prior ones. Inner-voice meaning, if it floated free of any such corrective practice, would not be meaning at all. See McDowell (1996, Lecture VI) for an interpretation of Wittgenstein’s target that frames the private-language argument as part of a wider attack on the very idea of a self-sufficient inner standpoint.

    [3] This phenomenological observation has been pressed hardest in the cognitive phenomenology literature, where authors like Strawson, Pitt, and Siewert argue that occurrent thought has a proprietary phenomenal character distinct from sensory imagery. The position I am defending here is compatible with that claim about what the phenomenology is like, while differing on its explanatory direction: the linguistic character of inner thought episodes is not evidence of a private language but of the public language doing its work silently.

    [4] Sellars, “Empiricism and the Philosophy of Mind” (1956), §§48ff. In the Jonesean myth, the genius Jones develops a theory according to which overt utterances are the culmination of a process beginning with inner episodes — theoretical posits modelled on the antecedent practice of public discourse, not items discovered through inward inspection. The relevant moral for the present essay: thought-talk is conceptually downstream from speech-talk, even when its referents are silent.

    [5] Crane, T. and K. Farkas (2022), “Mental Fact and Mental Fiction,” in T. Demeter, T. Parent and A. Toon (eds.), Mental Fictionalism: Philosophical Explorations (Routledge), p. 14 (ms.) — the quoted formulation is theirs, not Sellars’s; they gloss the Jonesean picture in this sentence. Crane and Farkas’s own positive thesis concerns standing mental states (beliefs, desires) as modelled via public ascription rather than directly inspected; the parallel I draw in the body extends this picture from standing states to occurrent inner speech episodes, and the extension belongs to the present essay, not to them.

    [6] The point that fluent linguistic surface is consistent with the absence of grounded meaning is developed at length in Jung, K. (2025), “Augustine, AI, and the Two Models of Language,” Journal of Religious Ethics 53(2): 217–238 — particularly Jung’s deployment of Wittgenstein’s meaning is use to argue that large language models succeed at the rule-governed dimensions of language game-play while failing to instantiate the non-linguistic, world-engaged dimensions that make use the right kind of use. Cf. also semantic externalism more broadly: Putnam (1975), Burge (1979).

    [7] The objection — that there is non-verbal thought — is sometimes pressed as if it refuted the broader anti-private-language line. It does not. The point about the private language argument is about the constitution of meaning, not the medium of cognition. Non-verbal animals and pre-linguistic infants can have intentional states whose contents are externalist in exactly the relevant sense: fixed by causal-historical relations to the environment, not by inner verbal labelling. The story I am telling about inner speech is a story specifically about the phenomenology of linguistic thinking — the inner voice as such — not a reduction of all cognition to inner monologue.
