J.L. Austin and the Slow, Excruciating Demolition of Indirect Realism

Posted on March 25, 2026 by gordon swobe

There’s a particular kind of intellectual pleasure in watching someone really good at argument dismantle a bad one. Not the quick knockout—the methodical, almost surgical kind, where the opponent doesn’t immediately realize they’ve been defeated. John Langshaw Austin specialized in exactly this. And in Sense and Sensibilia, his posthumously published Oxford lectures, he performed what amounts to a philosophical colonoscopy on indirect realism, also called sense-data theory. This theory had, for centuries, convinced smart people they’d never actually seen a red tomato.

Let me back up.

The Setup: You Can’t Trust Your Eyes

For a surprisingly long stretch of Western philosophy—roughly from Descartes through Ayer—a curious doctrine held center stage: you don’t perceive the world directly. What you actually perceive, in the privacy of your own mind, are sense-data: fleeting, subjective, mental intermediaries that stand between you and reality like a very unreliable middle manager. The tomato on your counter? You don’t see that. You see a red, round, tomato-ish something in your mental inbox, and the actual tomato hides behind it like a reclusive celebrity.

The argument for this view had a certain seductive tidiness. When you see a straight pencil in water, it looks bent. But the pencil isn’t bent. It is an illusion and you are seeing sense-data, so the argument goes.

“You cannot see the real pencil,” claims the sense-datum theorist, aka indirect realist.”The real pencil is straight. You are looking at your mental image of a bent pencil. You see sense-data, not the pencil itself, and this is always the case for all of your perceptions. You never actually experience reality directly. You experience reality only indirectly, via your internal sense impressions.”

Philosophers called this the Argument from Illusion, and they were quite proud of it. It seemed like a rock-solid case against direct realism in favor of indirect realism. Austin, however, was not impressed.

Enter Austin, Stage Left, Wearing a Look of Mild Contempt

Austin’s method had a quality that drove some colleagues mad and delighted others: he insisted on actually looking at what philosophers claimed before agreeing that they’d said it correctly. This sounds like a low bar. In mid-twentieth-century Oxford, it occasionally felt like a revolutionary act.

Sense and Sensibilia opens by targeting A.J. Ayer’s The Foundations of Empirical Knowledge—a book Ayer probably came to regret in the way one regrets a youthful tattoo. Austin announces that he’ll proceed “piecemeal,” examining the argument “word by word, almost.” Readers of a certain temperament will already feel the shiver of anticipation. This means Austin plans to be thorough.

He starts with what you might call the vocabulary problem. The sense-datum theorist leans heavily on words like “illusion,” “delusion,” “looks,” “appears,” and “seems”—deploying them as though they all meant roughly the same thing and collectively proved that perception involves an inner screen. Austin’s first move involves asking: do these words actually mean what the theorist needs them to mean?

They do not.

Austin noticed something that philosophers of perception had systematically overlooked: the words they relied on to build their arguments didn’t mean what they assumed. In Sense and Sensibilia — delivered as lectures at Oxford in the early 1950s and published posthumously in 1962 — Austin brought the full weight of ordinary language analysis to bear on the argument from illusion, and found it riddled with equivocations that close attention to English dissolves.

Take the word illusion. Philosophers had been treating illusions and delusions as though they occupied the same logical category — as though both involved the perceiver being systematically cut off from reality and presented instead with some inner substitute. But Austin points out that an illusion doesn’t require that you’re mistaken — a conjurer’s trick remains an illusion even when you know it’s a trick and aren’t taken in at all. A delusion, on the other hand, involves a strong conviction that resists correction. These two phenomena differ not just in degree but in kind. A mirage doesn’t function as a delusion: people who see one typically know exactly what they’re seeing and adjust their behavior accordingly. The philosophical move of lumping them together — treating all cases of non-veridical experience as evidence for the same conclusion about the nature of perception — involves a slide between two quite different concepts under a single borrowed word.

The deeper surgery Austin performs involves the verbs looks, appears, and seems. Philosophers had been reading these as technical terms that automatically signal indirect perception — as though saying “the pencil looks bent” commits you to the claim that you’re perceiving some inner bent-pencil-representation rather than the straight pencil itself. But Austin shows that ordinary usage carries no such implication. To say the pencil looks bent in water may simply describe what straight pencils do in certain optical conditions — a fact about how light behaves at the interface of two media, not a fact about the structure of your perceptual access. The locution reports a perfectly normal feature of the world, not evidence for an inner theater of appearances. Looks, appears, and seems carry different modal and epistemic freight depending on context: sometimes they hedge a claim (“it appears he left early — though I’m not certain”), sometimes they describe objective optical properties (“that surface appears darker in shadow”), sometimes they report a perceptual experience that the speaker knows conflicts with reality (“the tracks appear to converge, but I know they don’t”). Philosophers had been treating the third usage as the primary or paradigmatic one and building a theory of perception on that narrow foundation.

The payoff of this analysis isn’t merely negative. Austin doesn’t simply deflate bad arguments — he exposes the mechanism by which they generate false mystery. The argument from illusion gains its apparent force by presenting cases of perceptual variation and misrepresentation, then asking: if you can be wrong about what you see, what guarantee do you have that you’re ever in direct contact with physical reality? But the question presupposes that “direct contact” and “perceptual variation” stand in tension — that any case of looking-without-being commits us to a general theory of inner intermediaries. Austin’s diagnosis: the presupposition smuggles in a picture of how language about perception must work, and ordinary usage simply doesn’t confirm it. The grammar doesn’t force the metaphysics.

To say the pencil looks bent in water needn’t carry any implication that you’re perceiving the wrong thing; it may just describe what straight pencils do in certain optical conditions.

The theorist had been running all these distinctions together, and Austin—with the patience of a man who had clearly graded a great many undergraduate essays—separated them back out.

The Peculiar Problem of “Material Things”

One of Austin’s most entertaining moves targets the sense-datum theorist’s casual dismissal of “ordinary material things” as problematic objects of perception. Ayer and others had assembled a list of suspicious examples: the bent-stick illusion, mirror reflections, after-images, the round coin that “looks elliptical,” the distant mountain that “looks small.” From these cases, they concluded that material objects in general sit behind a veil of sense-data.

Austin’s response amounts to: you’ve got a very strange sample.

He points out that “material thing” doesn’t designate a natural, well-defined category that one can straightforwardly contrast with sense-data. What falls under it? Chairs? Shadows? Rainbows? The equator? Reflections in mirrors? The list of things you might see includes items of wildly different ontological statuses, and treating them all as members of one suspicious class called “ordinary material objects” commits what Austin considers a cardinal sin: mistaking a vague grammatical category for a deep metaphysical one.

Philosopher’s aside: there’s something almost endearing about a philosophical tradition that looked at the totality of what humans perceive—mountains, mirrors, afterimages, orange peels, other people’s faces, traffic lights—and decided the interesting question was whether any of it counts as real. Austin’s implicit reply: could you perhaps be more specific?

The Argument from Illusion Gets the Treatment

The real fireworks arrive when Austin turns on the Argument from Illusion itself. The argument, recall, runs like this: in illusion cases, you’re perceiving sense-data rather than the thing itself. In normal cases, the experience looks the same from the inside. Therefore, in normal cases, you’re also perceiving sense-data.

Austin identifies at least three things wrong with this, but let’s savor the best one.

The argument assumes that because two experiences resemble each other from the inside, they must involve perceiving the same kind of thing. Austin finds this assumption remarkable. When I look at a wax apple and a real apple and they look the same to me, it doesn’t follow that I’m perceiving the same type of object in both cases—one made of wax and one made of apple-stuff. The visual similarity doesn’t collapse the ontological difference. Why, then, should the similarity between a normal perception and an illusory one force us to conclude that both involve only inner sense-data, rather than concluding—far more sensibly—that the illusory case involves something unusual happening with the same kind of perceptual access we normally exercise on real objects?

The indirect realist has quietly smuggled in the assumption that needs proving: that if experiences match in character, their objects must match in kind. Austin just… declines to accept the smuggled goods.

The argument from illusion, he suggests, depends on a “very literal-minded” inference that ignores everything we know about how perception actually operates, how language about perception actually works, and what philosophers of perception actually need to explain.

The Deeper Target: The Inner Theater

What Austin dismantles isn’t just a technical argument. He takes aim at a whole picture—the image of the mind as a kind of inner cinema, where what you really perceive takes place on a private screen inaccessible to anyone else, while the world sits outside, casting projections through the senses.

This picture has a long philosophical pedigree. It flatters our sense that the mind occupies a privileged epistemic position (we know our own sense-data with certainty, even if the outer world eludes us). It generates the skeptical problems that kept Descartes busy. It makes consciousness look like a sealed theater showing a film about a reality the audience never directly touches.

Austin’s method—attending scrupulously to what words actually mean in actual contexts—doesn’t refute this picture by constructing a better theory. It dissolves the picture by showing that the arguments meant to establish it don’t establish it. The sense-datum theorist hasn’t discovered a truth about the hidden structure of perception; they’ve miscategorized some ordinary facts about illusion and misdescription, and then generalized wildly.

The theater, in other words, was always a philosopher’s confection. Nobody actually lives there.

The Aftermath

Sense and Sensibilia didn’t kill sense-datum theory—philosophical theories don’t die, they just acquire increasingly small audiences. But it did something arguably more useful: it shifted the burden of proof. After Austin, you couldn’t just invoke the argument from illusion as though it obviously worked. You had to defend your vocabulary, justify your inferences, and explain why “the stick looks bent” committed you to anything more exotic than the observation that water refracts light.

This turns out to be hard. Most philosophers working on perception since Austin have quietly moved away from the classic indirect realist picture, even when they haven’t explicitly credited him.

And perhaps that’s the most Austinian outcome of all—a revolution that looked, from the outside, like someone being very careful about words.

The Phenomenological Fallacy: The Root of the Internal Theater

Posted on January 19, 2026 by gordon swobe

In the philosophy of mind, few logical errors have caused as much damage as what U.T. Place famously termed the “Phenomenological Fallacy.”

At its simplest, it’s an introspective misread: in describing what it’s like to see, hear, or feel something, we treat those descriptions as reports about the intrinsic qualities of inner mental objects or processes instead of reports about how our experience represents the world. 

This error is a primary motivation for mind/body dualism. It convinces us that because our visual experience is colorful, our mind must contain “colored things” that are distinct from the grey, squishy matter of the brain.

History and Origin

The term was introduced by U.T. Place in his landmark 1956 paper, “Is Consciousness a Brain Process?”

At the time, the dominant view in perception was the Sense-Data Theory, also called Indirect Realism, championed by philosophers like G.E. Moore, Bertrand Russell, and H.H. Price. They argued that when we hallucinate a green dragon, since there is no actual dragon, we must be seeing a non-physical “sense-datum” that really is green and really is dragon-shaped.

Place argued that this was a logical error. He contended that when we have a “green after-image,” we are not reporting on a phosphorescent green object floating in a “phenomenal field.” We are merely reporting that we are in the sort of brain-state that normally occurs when we look at green objects in the world. To assume the experience of greenness must itself be green is to commit the Phenomenological Fallacy.

The Mechanism of the Fallacy

The fallacy works by confusing the properties of the object represented with the properties of the representation.

The Painting Analogy Consider a painting of a fire. The painting represents fire, which is hot and bright. But the painting itself is not hot, nor does it emit light. The Phenomenological Fallacy is the equivalent of arguing, “I see a fire in the painting, fire is hot, therefore the canvas must be hot.”

In the mental case, the logic proceeds as follows:

  1. Premise: I have a visual experience of a red strawberry.
  2. Fallacious Inference: Therefore, there is a “red strawberry” image or construction in my mind.
  3. False Conclusion: Since my brain is grey and contains no images or models of red strawberries, my mind cannot be my brain. Some form of dualism must be true.

Common Mistakes Rooted in the Fallacy

By accepting this inference, philosophers are forced into a corner, leading to several major mistakes in the philosophy of mind:

1. The Reification of Sense-Data (Mental Paint)

This is the most direct consequence. Philosophers reify the “look” of the world. They posit that the mind is full of non-physical “mental paint” or qualia that possess properties like “redness,” “loudness,” or “painfulness.”

  • Why it’s a mistake: as representationalists like Michael Tye point out, experience is transparent. When we introspect, we don’t find “mental paint”; we look through the experience to the properties of the object of perception. The “redness” belongs to the strawberry (or the hallucinated strawberry), not to the mind or brain.

2. The “Act-Object” Fallacy

This is the failure to distinguish between the act of sensing and the object that is sensed.

  • The Mistake: If I hallucinate a pink elephant, the object (the elephant) does not exist. The Phenomenological Fallacy leads us to imagine an internal object (a sense-datum) to fill the gap.
  • The Correction: We should instead say the act of sensing (the brain state) exists, but it is an act that misrepresents reality. You can have a representation without a target, just as you can have a map of Narnia without needing a “real” land of Narnia.

3. Invalid Arguments Against Physicalism (Leibniz’s Law)

Many arguments against physicalism rely on this fallacy. The argument usually goes:

  • Premise 1: My after-image is chartreuse.
  • Premise 2: No state in my brain is chartreuse.
  • Conclusion: Therefore, my after-image is not a brain state.

The Mistake: This violates U.T. Place’s “is of definition.” The after-image isn’t a thing that is chartreuse; “having an after-image” is a process. The experience of chartreuse does not need to be chartreuse, just as a computer file representing a photo of a hurricane doesn’t need to be wet and windy.

4. The Cartesian Theater (The Homunculus)

If we believe “phenomenal objects” (images, sounds, smells) reside inside the head, we implicitly posit a spectator to observe them—a “little man” (homunculus) in the brain watching the internal movie screen.

  • The Mistake: This leads to an infinite regress (who is watching the movie inside the homunculus’s head?). Dennett and Searle have both criticized this, noting that consciousness is where the processing stops, not where it is re-displayed.

Conclusion

Recognizing the Phenomenological Fallacy is the first step toward a coherent non-dualistic theory of consciousness and perception. We can accept that we experience rich, colorful phenomenology, without assuming our brains are literally filled with colorful, non-physical ghost-objects.

Michael Tye and the World-Directed Mind

Posted on November 26, 2025 by gordon swobe

Michael Tye is one of the few contemporary philosophers of mind who seek to naturalize consciousness without either hand-waving or mysticism. His core claim is disarmingly simple:

What it’s like for you to have an experience is nothing over and above how your world-directed mind represents the world.

No inner glow, no private mental paint, no secret inner theater, no separate free-floating inner qualities of experience (no inner quaila).

On Tye’s intentionalist view, a conscious experience is a certain kind of world-directed representational state. Once you understand that state—what it represents, and how—it leaves nothing “extra” for qualia to be.

This runs straight against the familiar picture of sense-data theory, also called indirect realism, in which we peer inward at a private show and infer the outer world only indirectly. Tye dismantles that picture and replaces it with a mind that is fundamentally outward-facing.

1. From Qualia to Representation

The traditional starting point is qualia: the supposed raw, ineffable “feels” of experience—the redness of red, the sharp sting of pain, the musty smell of old books. On the standard view, these are inner items you are directly aware of:

  • You look at a red tomato.
  • Light hits your eyes; your brain does some processing.
  • Then, inside your mind, there is a private red inner mental object you are immediately aware of.
  • The tomato is known only indirectly, via this inner qualitative intermediary.

This indirect realism could be called the inner show model. It brings with it the usual philosophical baggage: the veil of perception, sense-data theories, inverted qualia scenarios, zombies, and so on. If what you encounter first and directly are inner objects, then the external world becomes something your mind must reconstruct from behind the curtain.

Tye’s move is to refuse that starting point. Experiences are not primarily inner objects at all. They are intentional states—states that are about the world. Phenomenal character is just a particular way that the world is represented in such states.

On this view:

  • You do not first encounter inner red mental paint and only then infer an outer tomato.
  • You are directly aware of the tomato itself as red, as shiny, as round, and as over there on the table.
  • The redness of the experience is simply how your visual system represents the tomato’s surface properties. It appears this way under those lighting conditions.

Once you have the right sort of representation in place, there is no further ontological work left for qualia to do.

2. Transparency: Looking Through Experience

One of Tye’s favorite starting points is the transparency of experience.

Try to introspect your visual experience right now. Stare at a strawberry, a coffee mug, whatever happens to be in front of you. Ask yourself: what exactly am I attending to?

When you do this honestly, your attention keeps going straight through to the world: the red of the berry, the smooth ceramic, the highlight on the rim of the cup, the shadows in the background. You don’t discover a second object—a mental screen with colors painted on it. You discover the world.

This is what it means to say that experience is transparent: when you “look into” it, you find not inner objects, but outer ones presented a certain way. That is a data point any theory of consciousness must respect.

For intentionalists like Tye, transparency is evidence that:

  • Phenomenal character is world-directed rather than self-directed.
  • The properties that show up in experience are the very properties your brain attributes to things out there—colors, shapes, motions, locations, bodily conditions, threats, opportunities—not inner qualia.

Experience, in that sense, is not a window on an inner show. It is already a window on the world.

3. PANIC: The Official Package

One of Tye’s important contributions to representationalism/intentionalism is his technical account of conscious experience under the admittedly unfortunate acronym PANIC:

Poised, Abstract, Nonconceptual, Intentional Content.

The idea is that a mental state is phenomenally conscious just when it has PANIC content:

  1. Intentional content The state represents something as being some way. A visual state represents a red, round object over there; a pain state represents damage or disturbance in a body region; a fear state represents something as dangerous.
  2. Nonconceptual The content of experience is richer than what you can describe or think under concepts. A child can see subtle shades they have no words for. So the representational content of experience cannot be limited to what the subject can conceptually articulate.
  3. Abstract Experiences represent not just bare particulars but properties and relations: red, shiny, curved, located to the left, moving closer, threatening, nourishing, and so on. These are abstract, repeatable properties, not private mental paint.
  4. Poised This is Tye’s way of distinguishing conscious from unconscious representation. A conscious state’s content is poised to directly influence belief formation, reasoning, and deliberate action. It is globally available to the cognitive system, not locked away in some local module.

So, for Tye:

A conscious experience just is a representational brain state with abstract, nonconceptual content that is poised for direct use in thought and action.

When you add up those features, there is nothing left over for “qualia” in the traditional sense to be.

4. Color: The Test Case

If any domain screams “qualia,” it is color. The redness of red feels like the paradigm case of a pure, inner quality.

Tye’s treatment of color is deliberately deflationary:

  • Color experiences represent physical surface properties—roughly, ways of reflecting and absorbing light, together with illumination conditions.
  • When you see a ripe strawberry in normal daylight, your experience represents the strawberry’s surface as having a certain reflectance profile that typically produces that pattern of stimulation in creatures like us.
  • The phenomenal character of seeing red is nothing over and above being in a state that represents that kind of reflectance property, under those conditions, with PANIC-style poise.

So where is “redness” located? It is not in a private mental paint pot, nor is it some spooky nonphysical property of the strawberry. Redness is the property your visual system attributes to surfaces—the property they are represented as having—when the system is functioning normally in the relevant environment.

What about color illusions?

  • In odd lighting or carefully crafted displays, your experience can misrepresent. You might see a gray square as lighter than an identical gray square in a different context, or take a blue dress for white.
  • That doesn’t show that color is inside your head. It shows that your world-representing system, like any representational system, can get things wrong.
  • Illusions are cases where the representational content is out of step with the actual physical properties, not cases where inward qualia detach from outward reality.

Color is a particularly vivid instance of world-directed representation, not evidence for an inner theater.

5. Pain, Bodily Sensation, and Emotion

Visual perception is the easy case for representationalism. The real question is whether the same treatment can handle pain, bodily sensations, and emotions, which feel more “inner” and more affectively loaded.

Tye’s answer is again systematic:

  • Pain represents damage (or threat of damage) to bodily tissue in a specific region. The “hurtfulness” of pain is just how that bodily condition is represented in a state that strongly motivates avoidance and protective behavior.
  • Bodily sensations—hunger, thirst, pressure, tickle, fatigue—represent various homeostatic and bodily states. They are signals about what is going on in the organism, represented as calling for certain patterns of behavior.
  • Emotions represent evaluative properties of situations: danger, loss, offense, injustice, betrayal, opportunity, and so on. Fear, for example, represents something as dangerous and to-be-avoided.

The unifying thought is that there is no special ontological category of “raw feels” floating free of representational content. A pain feels the way it does because that is how the brain represents the relevant bodily condition when the content is poised to influence thought and action in a characteristically urgent way.

So phenomenal character is still content, just content with a specific functional and motivational profile.

6. Mary’s Room and Phenomenal Concepts

No contemporary philosopher of mind gets to ignore Frank Jackson’s famous thought experiment about Mary’s Room:

  • Mary knows all the physical facts about color vision.
  • She has lived her whole life in a black-and-white environment.
  • When she steps out and sees a red tomato for the first time, it seems undeniable that she learns something new—what it is like to see red.

Many take this to show that physicalism is incomplete: there must be non-physical facts—facts about qualia—that Mary did not know.

Tye’s reply is to grant the intuition of “new knowledge” while resisting the metaphysical leap. The rough story:

  • Before leaving the room, Mary has never been in the relevant PANIC state—the state that represents a red surface in the right poised way.
  • When she sees the tomato, she acquires a new nonconceptual representational state and the associated phenomenal character.
  • She also acquires a new phenomenal concept—a recognitional way of thinking that is directly tied to that type of experience. She can now think, “that kind of experience,” where the “that” is anchored in her new state.
  • The knowledge she gains is not a new non-physical fact about the world. It is a new way of accessing and classifying physical facts she already knew under purely theoretical descriptions.

In other words, the so-called “explanatory gap” is a conceptual gap tied to our limited cognitive apparatus, not an ontological gap in the world itself.

7. Why Tye’s View Matters

Why bother with all this? What is the payoff for taking Tye and strong intentionalism seriously?

  1. Consciousness stays in the physical world. On Tye’s view, conscious experiences are representational brain states, with content fixed (at least in part) by the organism’s relation to its environment. No extra substance, no ghostly properties, no fallback to mysterianism.
  2. Experience is world-facing, not screen-bound. When you see a strawberry, you are not primarily aware of an inner image that might or might not correspond to a strawberry. You are aware of the strawberry itself as red, ripe, and edible. This fits how perception functions in everyday life: as a way of coping with the world, not as a spectator sport.
  3. Perception, pain, and emotion form one family. Tye gives a single representationalist treatment of vision, bodily sensation, and affect. Instead of a patchwork of special cases, we get a general story: the mind is a system of world- and body-directed representations, some of which are poised to guide thought and action in distinctively conscious ways.
  4. Qualia talk is explained, not enshrined. The temptation to posit irreducible qualia is made sense of as a by-product of transparency, limited introspection, and our cognitive habits. We do not need to grant qualia special metaphysical status just because they feel compelling from the armchair.

None of this settles every objection. Critics will press on whether content alone can really account for all aspects of phenomenal life, whether “poise” smuggles in a higher-order theory in disguise, and whether externalist content sits comfortably with our first-person certainty about how things seem.

But part of Tye’s value lies in forcing those questions into the open. If you want to say more than he does, you have to specify exactly what you think experience adds beyond PANIC content—and why that addition doesn’t collapse back into either dualism or mystery.

8. Conclusion: No Inner Theater Required

Tye’s strongly intentionalist philosophy of mind can be read as a sustained refusal to postulate more mental furniture than we actually need. There is no inner stage with mental actors and mental scenery. There is only a physically realized, representational system that keeps an organism tightly coupled to its world and its own body.

On that picture, to understand consciousness is not to peer into a hidden inner domain. It is to understand how a brain can carry information about the world and the body in a way that is poised for use in thought and action—and how, when we look “inward” at our experience, we inevitably look straight through those processes to the world they disclose.

That is the world-directed mind. No mental paint, no private screen, no veil of perception, no inner theater—just a creature in a world, representing things as being a certain way, and sometimes getting it wrong.

Intentionalism in Perception

Posted on October 31, 2025 by gordon swobe

by Gordon Swobe

Descartes gave modern philosophy both its clarity and its curse. His clarity lay in putting the conscious subject at center stage: the “I who thinks” as the starting point for knowledge and inquiry. His curse lay in treating that epistemic starting point as evidence for two ontologically separate substances—res cogitans and res extensa—forever divided by a metaphysical chasm.

That division led to the development of mind–body dualism in the philosophy of mind and contributed to the emergence of what is now known as indirect realism in the philosophy of perception. After building that wall between mind and world, philosophy spent four centuries trying to tear it down.

The Landscape of Theories

To see how intentionalism in perception clears this ground, it is helpful first to compare it with two other important theories of perception, direct and indirect realism.

Direct realism, also known as naïve realism, is the common-sense view that we perceive the world directly, without mental intermediaries. In its naïve form, it assumes that things appear exactly as they are. More sophisticated direct realists accept that the brain plays a causal role but deny that this makes perception indirect. When you see a strawberry, you are directly aware of that very strawberry.

Indirect realism, descended from Descartes and Leibniz and systematized by Locke, holds that what we perceive immediately are inner objects—ideas, sense-data, or internal representations—caused by the external world. From these inner objects of awareness, the external world is inferred. This view gives rise to what philosophers call the veil of perception: if we see only our inner images, the world itself becomes epistemically invisible. The theory also doubles the ontology: the red strawberry exists both physically and as a mental image.

Intentionalism in perception is not to be confused with intention in the everyday sense of choice or will. The word comes from intentionality—Brentano’s term for the “aboutness” or directedness of mental states. To perceive, believe, or desire is to be about something in the world being a certain way.

Intentionalism treats perception not as the inspection of inner mental objects but as a representational relation to the world itself. To experience is to represent the world as being a certain way. The phenomenal character of that experience—what it is like—is identical to, or wholly determined by, its representational content.

When you see a banana as yellow, you are not looking at a yellow picture in your mind; you are in a representational state about the banana. The representation is your way of being aware of it, not a thing you perceive in addition to it. Your experience is the representation.

Intentionalism thus retains the explanatory power of representational theories while eliminating their metaphysical baggage. One world, one act of representing, one ontology.

​

Descartes’ Divide

I am not directly acquainted with the external objects themselves, but only with the ideas of them which are in me.

— Descartes, Meditations (1641)

This idea from Descartes’ philosophy advanced and established the view of indirect realism, later inherited and developed by Locke and Hume.

Once perception is defined as awareness only of inner mental ideas and images, skepticism of the external world follows immediately: if we can never compare our internal ideas of objects with the external objects, how can we know if our ideas match the objects? How can we know the external world even exists?

Descartes famously imagined that a demon might have taken control of his ideas of the world, and so “Cartesian doubt” was born. The veil of perception had descended on philosophy.

To overcome his doubt of the external world beyond his mind, Descartes appealed to God; only God could save him from his mistaken epistemology! Locke appealed to resemblance; Berkeley abandoned the external world entirely.

A few philosophers have interpreted Descartes’ view as a form of direct realism, in which his inner ideas directly reveal the objects of perception; this approach suggests an intentionalist perspective.

Intentionalism begins by refusing to construct that inner veil of perception. There is no need for an inner object of perception between the perceiver and the object of perception, as the perceiver’s awareness already is of the external world.

Two ontologies for one object is bad metaphysics. Intentionalism restores unity.

Perception is only one of many kinds of intentional states

Any mental state about or of something is an intentional state. Here are some important types of intentional states:

  1. Intentions and plans
    Examples: intending to go for a walk; planning to write a book; resolving to quit smoking.
  2. Emotions with objects
    Examples: fearing a recession; loving your partner; resenting your boss; admiring a philosopher.
  3. Cognitive attitudes
    Examples: judging that the Fed will cut rates; doubting that AI will ever be conscious; suspecting that a witness is lying; hoping that Bitcoin rallies; expecting a delivery tomorrow.
  4. Modal or hypothetical attitudes
    Examples: wishing you had chosen a different career; regretting a past decision; wondering whether color experience could have been inverted; supposing that you’re in a simulation, for the sake of argument.
  5. Memory and anticipation
    Examples: remembering your last vacation; anticipating a difficult conversation; recalling an argument.
  6. Linguistic or speech-act–related states
    Examples: promising to meet someone; asking a question; ordering someone to leave.
  7. Perception
    Examples: seeing a red strawberry, smelling a rose.

    All of these have representational content (what they are about: this person, that outcome, that proposition) and conditions of satisfaction (what it takes for them to be fulfilled, correct, answered, kept, etc.)

    In this way, perception finds its proper place as just one of many faculties of the world-directed mind.

Illusions

The indirect realist points to illusions as evidence that perception cannot be direct, but illusions show only that our representations can be incorrect. In an illusion, the error lies in the content of the experience, not in any intervening object.

Intentionalism can describe this precisely: perceptual content always has aspects, such as shape, color, and size.

Consider a pencil in a glass of water. Because of refraction, it appears bent/broken. We know this bentness is an illusion, but it does not follow that we cannot see the pencil in any way and are instead perceiving an inner image. Illusion demonstrates only that representations can be inaccurate; they do not reveal a veil between the perceiver and the perceived object.

Hallucinations and Dreams

Hallucinations share the same format as veridical (tryperceptions: they represent the world as containing certain objects and properties. In a dream or hallucination, one’s physical brain state is identical to veridical experience in all relevant respects. The difference is that their contents lack referents; their conditions of satisfaction are not met.

In genuine perception, the world satisfies the content. In hallucination, it does not. There is no need for a special inner image to explain why hallucination feels like perception. Both involve the same kind of representational state; they differ only in whether the representation is true.

Dreaming is the same. A dream constructs a temporary false world-model. Waking is not a return from an inner movie but an update—an act of realizing that one’s previous world-model was false.

Science Without a Theater

Neuroscience tells the causal story: wavelengths, photons, neural transduction, cortical representation. None of this implies that perception occurs on an inner screen. Neural activity realizes representational content; it does not project it for a viewer inside the skull.

The scientific and phenomenological descriptions are complementary: the third-person account explains how representation arises, and the first-person account describes what that representation is about. They are not competing descriptions but two sides of one coin.

Directness Without Naïveté

Intentionalism combines what was right in both earlier views. Like direct realism, it holds that we are aware of the world itself, not of inner pictures. Like indirect realism, it acknowledges that perception is representational and sometimes mistaken. Perception is direct as it is of the world and not of any intermediate objects, and representational because it presents that world under particular aspects.

Dissolving the Veil

Most importantly, intentionalism dissolves the veil of perception. If perception consisted in awareness of internal objects, the world itself would remain unseen and skepticism of the external world would follow naturally. Intentionalism removes the veil by redefining what it means to represent.

To represent is not to look at a mental copy but to stand in a world-directed mental state the contents of which represent the world.

This preserves everything science has discovered about the brain’s representational machinery while restoring epistemic contact with the world that machinery evolved to represent

Intentionalism keeps what was right about Descartes—the mind’s activity—and discards what was wrong—its isolation. There is no inner stage, no audience, no second world inside the head, no Cartesian theater. Perception is not a private inner show; it is the organism’s mode of direct openness to its environment.

Intentionalism drives out Descartes’ ghost once and for all, banishing the fever dreams of evil demons, brains in vats, and Matrix movies. Perception is world-revealing, not world-concealing.

Indirect Realism: proper method, bad metaphysics

Posted on October 30, 2025 by gordon swobe
Indirect realism creates a veil of perception

Modern philosophy, in its pursuit of scientific rigor, made a category mistake in indirect realism. It applied a sound methodological approach to science, but inflated it into metaphysical dogma about consciousness and perception.

Indirect realism originated from Descartes’ cautious perspective, which posits that we never directly observe nature but rather perceive it through its effects, such as light waves or nerve firings. This approach maintains scientific integrity by acknowledging the limitations of our instruments in capturing what we can observe.

However, after human perception was itself declared indirect, we required an ethereal inner observer to witness the show. The brain became a projector, and consciousness, a movie.

Who is that supposed inner spectator in your mind? Doesn’t that inner observer also have a mind? Philosophy has struggled to escape that Cartesian theater ever since.

Intentionalism, a theory of perception, asserts that perception is not a private mental process but a world-directed act of representation. When you perceive a red strawberry, you don’t see a mental redness in your head; instead, you perceive the strawberry as red. The mind doesn’t act as an intermediary, inserting an image between you and the world.

Science still needs its instruments and models. It must remain “indirect” in method, but consciousness itself is not a measuring device. It is not an inner laboratory. It is the world coming into presence.

The great philosophical error was to confuse epistemology for ontology — to turn the scientific stance into a metaphysical picture of the mind. Intentionalism restores order by putting each in its proper place.

We can have mediated knowledge without mediated experience. Science can remain indirect while life remains direct. Science models reality. Consciousness presents it.

The Diaphanousness of Experience

Posted on October 21, 2025 by gordon swobe

The diaphanousness of experience refers to the fact that when we inspect our experience of the world, we cannot perceive our experience itself. Instead, we only experience the world as it seems to us.  


Even if we hold that naive/direct realism is false, strawberries seem red on their surfaces, and there’s nothing we can do about it.


Now, let’s compare perspectives:

The indirect realist believes he is deceiving himself. He claims to perceive an inner image of a red strawberry that he claims to be projecting outward onto the external strawberry, which he cannot actually see or apprehend directly.

Is the world really so deceitful?

The intentionalist takes diaphanousness at face value. He acknowledges that the strawberry is external to him and that he is representing it as red. He’ll happily agree that the naive/direct realist’s theory is flawed. Still, he maintains that he is representing a red strawberry in the world, not just some mental image that sits between him and the strawberry.

When the intentionalist says his experience is about the strawberry, he is saying it is about that strawberry out there in the world that seems a certain way, and not about any supposed internal image or model of it. 

This preserves the common sense notion that the world is visible. When you open your eyes, you are not looking at an internal mental image of the world that sits between you and the world. You see the world.
