The Partially Examined Life

Consciousness Is Not a Theater: Dennett Says Experience Just Is Judgment

Dennett's "multiple drafts" model denies there's a central screen in the brain: there is no two-step of "first feel, then judge" — experience itself is the distillate of a pile of parallel judgments.

Four people work through Dennett's text paragraph by paragraph and make clear what "illusionism" actually denies; but it meanders a lot and is dense with terminology, so it's tough going without a philosophy background.

Seeing is not knowing, and Dennett says there's no such distinction

Mark raises a key distinction: is experiencing something one thing, and acquiring a fact about something another? In the phi phenomenon, you "see" the first dot move and become the second dot, but in fact it didn't. Dennett's position is that there is no difference between the two at all. You know the dot didn't move because the book told you, just as you know the chopstick in the water is straight even though it still looks bent. Dylan supplies the mechanism: the thing in your consciousness closest to a "full experience" is really just the pile of judgments you've already made, and those judgments can be revised at any time in light of new information.

An illusion requires a prior expectation to hold

Seth objects to the example itself: for a straight chopstick to look bent, the illusion presupposes that you already know it's straight, or have had the experience of it being straight, and expect it to look straight. If you'd never seen this chopstick and walked up and saw it bent in the water, you'd have no basis for judging whether it's straight or bent. So an illusion isn't passive reception; it's a structure involving cause, effect, and preconditions. Dylan follows up: no experience is ever without a frame — you always see, hear, and experience with a whole set of expectations.

Memory is the only thing close to a "final draft"

Dylan points out that the thing closest to a "fixed display" is the record you write into memory and later retrieve, and that itself can be wrong. He adds something Dennett doesn't state outright: the multiple drafts aren't all continuously active — they're also interacting with memory. Christopher sums it up as a "distributed process": these interpretive processes run simultaneously and are continuously revised, and no fixed display ever occurs. This directly kills off the "central screen" of the Cartesian theater.

— Dylan

Heterophenomenology: listen to people, but don't take it at face value

Mark explains heterophenomenology: it's third-person phenomenology — you listen to people describe their experience in the first person, but you can't take it directly as veridical. Dennett holds that the introspective method used by William James and his crowd is fundamentally flawed — even when you ask in the first-person plural, as in "I have this experience, don't you too?" Dylan adds: then the method should also be applied to oneself, and Mark says Dennett does exactly that at the end of the book.

— Mark
16:53

Illusionism denies not experience but its properties

Christopher clarifies: the word illusionism is terrible, but it doesn't claim experience doesn't exist — it claims our phenomenal experience is a misrepresentation. The mechanism is real, running on the brain, but the thing it depicts doesn't have the properties people think it has — those intrinsic, ineffable properties. So "he denies felt experience" is a misreading, and a stupid one. The genuinely hard question is: what does it even mean to say it lacks these particular properties? What does our felt experience have over and above being functional?

— Christopher
20:12

Why a mirage doesn't count as an experience

Here Dylan goes head-to-head with Dennett. He says: I can perfectly reasonably say that what I experienced was a red dot crossing the page and becoming a blue dot, and there's no contradiction in that. If I see a mirage, why doesn't that count as an experience of it? Even if my eventual conclusion about "what that is" differs. Mark sides with Dennett's critics: direct experience contains the judgment "there's water there," and ultimately you'll judge there's no water there, so appearance and judgment sound like two different things. Dylan's conclusion: Dennett is really saying all experience is judgment.

— Dylan
31:35

"What it's like to be Seth" is not a thing

Seth states Dennett's complaint about qualia most clearly: why add another ontological element to the equation? Why add another thing? His replacement is: we stand in an evolutionarily complex, dynamic, discriminating, constructive relation to our environment, and "what it's like to be Seth" is the experience of all that operating at once — it needn't be treated as a thing, needn't be reified. Mark follows Peirce: the moment you try to say what an experience is, you've already connected it to other experiences and memories.

— Seth
32:58

Stalinist revision and Orwellian revision

Mark cites the example on pages 117 to 118 of the book: you're standing on a street corner and a woman with long hair walks briskly past; about a second later, a subliminal memory of some earlier woman with short hair and glasses contaminates the memory of what you just saw. Asked for details a minute later, you sincerely but falsely report that she wore glasses. That's Orwellian revision — rewriting after the fact. Stalinist revision is when you saw her as wearing glasses from the start. Dylan says only by admitting there's a stream of "the facts themselves" can you distinguish the two; and Dennett precisely denies that stream exists — all that exists is judgment.

— Mark
37:27

No probe, no experience

Mark gives the most practical point of the episode: unless someone asks you, has you write it down, or has you press a button in an experiment — in short, unless there's some probe — those drafts just drift apart. A probe can touch any one of the drafts, and they may differ from one another. If at the time you said "wait, look at that woman," you'd clearly see and remember that she wasn't wearing glasses; but if you didn't probe at that point, Dennett claims it doesn't count as an experience, because your attention never landed on it. This is the figure-ground problem.

— Mark

In their own words · checked verbatim

there's nothing that you experience that doesn't come without a frame for that experience.

Dylan4:43

The closest thing to the fixed display ends up being what you end up writing down in your memory that you refer back to. And even that could be wrong.

Dylan5:54

it doesn't make any sense to me that there's a distinction between the feeling of being conscious and the act of judging.

Dylan23:43

the experience of consciousness is. Experience of me is just a living being that's making judgments and decisions and conclusions about the world. And that's the experience of being conscious. That's what consciousness is.

Dylan24:46

when you say that your felt experience is something that is a conclusion that's made up by your active combination of your memories and your active thinking about the world, and that's distinct from the flow of chemicals and electrical pulses that are through your body, that somehow it's not merely explained by, and therefore it's an illusion. That conclusion I just find totally bizarre.

Dylan41:09

why does liquidity at all come along with the H2O and the chemicals involved, the chemical process?

Christopher42:19

There's no thought that, you know, it's the pineal gland that is there receiving all the information and making all the decisions or something like Descartes would say.

Mark46:19
