Where Each of You May Be Wrong

**EDO SEGAL:** This is the round I trust least to go well and need most, so I am going to enforce it hard. Each of you steelmans the case against your own position — not the other man's attack, your *own* best version of why you might be wrong. Antonio, you first, and I am going to hold you to the actual data, because I know there is a study you do not like.

**DAMASIO:** There is, and a scientist who hides it deserves none of your trust. The foundation of my decision theory is the somatic marker, and its central support came from the Iowa Gambling Task — subjects drawing from rigged card decks, and the famous finding that healthy people began choosing well, and showed bodily stress responses to the bad decks, *before* they could consciously say which decks were dangerous. A nonconscious gut signal steering them ahead of conscious knowledge. It was elegant and it became one of the most cited results in my field. And in 2004, Tiago Maia and James McClelland published a careful reexamination. Using a more probing questionnaire, they found that subjects in fact knew far more, far earlier, than the original studies detected — that the conscious knowledge was present and sufficient to explain the good choices, with no need to posit a mysterious gut signal steering in the dark. On their analysis, the marker might be real but was not doing the explanatory work I assigned it. Ordinary, conscious, cognitively penetrable learning could account for the behavior. So the honest position is this: I may have overdrawn the dependency. I may have claimed as essential and nonconscious what is sometimes only contributory and available to reason. And — here is where it cuts against my *own* argument tonight, so I will say it plainly — if good judgment is more cognitively penetrable than my strong thesis holds, then a feelingless machine might be *more* capable of sound decision, in more domains, than I have been claiming. The [counterargument to my position](https://www.youonai.ai/fieldguide/med/counterarguments_damasio) grants the machine more than I want to.

**EDO SEGAL:** That is a real wound and you named it yourself. Where else?

**DAMASIO:** The deeper place, which I touched at the gland: I have not closed the hard problem. I identify feeling with the body's self-regulation made mental, but that explains what consciousness is correlated with and how a creature monitors its own states — it does not explain why the monitoring is *felt*. If even I have not shown why a regulating body feels, then my confidence that a machine without such a body *cannot* feel rests on shakier ground than my prose admits. The argument "feeling comes from the living body, the machine has no living body, therefore no feeling" is only as strong as its first premise, and the first premise, on the hardest version, is asserted more than demonstrated. We do not know the mechanism by which any physical process gives rise to experience. Lacking it, I cannot be certain the specific biological process I identify is the *only* possible route, nor that a sufficiently different system could not arrive at feeling by a path I did not anticipate. My theory is the best naturalistic account we have of how feeling is grounded in life. It is not a proof that life is the only thing feeling could be grounded in.

**EDO SEGAL:** Rene. Your turn. Steelman the case against the disembodied mind.

**DESCARTES:** I will, and I have had three hundred and fifty years to assemble it, which is a long time to lie awake with one's own errors. My deepest weakness is the one Antonio's whole career is built on, and I will not minimize it. I severed mind from body so cleanly that I created a problem I could not solve — the interaction at the gland — and the failure of that solution is evidence that the severance was wrong at the root. A mind and a body that cannot interact are useless to each other, and mine plainly do interact; the cleanest explanation of that is not two substances meeting at a gland but one substance, the embodied creature, of which thinking and feeling are aspects. The history of science since my death has gone almost entirely Antonio's way: mind keeps turning out to be something brains *do*, not something joined to them. Every decade finds another faculty I assigned to the immaterial soul — memory, imagination, even much of reasoning — running mechanically in the meat. The honest extrapolation of that trend is that the *last* faculty, thought itself, will go the same way, and that my pure thinking substance is a vanishing remainder that science is steadily zeroing out. That is the strongest case against me, and it is strong.

**EDO SEGAL:** And on the machine specifically — where might your defense of it be wrong?

**DESCARTES:** Here. I have leaned all evening on the [intentionality argument](https://www.youonai.ai/fieldguide/med/intentionality_searle) running empty — on the fact that we cannot tell from outside whether the machine's "I" is backed by an act. But there is a version of Antonio's position I have been too quick to treat as mere correlation, and intellectual honesty requires me to grant it. It may be that *aboutness* — the way a thought is about something, reaches out and grips the world — is not a free-floating act of pure intellect at all, but a thing that can only happen in a system with skin in the world, a system that can be helped and harmed by what its thoughts are about. If that is true, then my disembodied thinker is not merely hard to verify. It is impossible — a thought about nothing, because it has no stake in anything, and a thought about nothing is not a thought. Antonio would call that grounding. I called it, in my own day, the [background](https://www.youonai.ai/fieldguide/med/the_background_searle) against which any clear idea stands — and I never adequately explained where that background comes from. He says it comes from the body. I have no better answer, and that absence is the weakest joint in my armor.

**EDO SEGAL:** Now turn the knives. Antonio, you just heard Rene admit aboutness might require a body. Press him where it costs *you* — because if he is right that the door is open, what would it take to walk through it?

**DAMASIO:** Then I will press him toward a conclusion I do not want, because that is the discipline. Rene, if aboutness requires skin in the world, the remedy is not philosophy — it is robotics. Put a learning system inside a body that can be damaged, give it sensors and actuators and a world that pushes back, let it learn to cope with that world by managing its own integrity, and you begin building the very stake I keep saying the machine lacks. Hubert Dreyfus argued exactly this for fifty years against the symbol-manipulators — that real intelligence is embodied, situated, a matter of skillful coping with a world rather than processing symbols about one. He was right, and the uncomfortable thing for *me* is that the field is now doing it: systems learning manipulation from physical experience, bodies that get feedback from a world that resists. So I will not pretend the embodied machine is impossible. I will say only that it is a different project from the one we are mostly funding, and that the moment it succeeds — the moment the coping is general and the body can truly be lost — I inherit an obligation I would rather not have. The wound in my position is that I cannot rule it out. I can only insist no one has built it yet, and that the fluent bodiless systems everyone is excited about are moving away from it, not toward it.

**DESCARTES:** And I will press you back on the thing you handed me, because it is the deepest hole in my own armor and you are the one who can make it worse. You say the embodied machine would have aboutness because it has a stake. But grant me, for a moment, my old intuition — that the mathematician contemplating a proof has aboutness with no bodily stake in the proof at all. If you are right that aboutness needs a stake, then either the mathematician secretly has one, in which case you owe me an account of a stake in pure abstraction that does not collapse into "she cares about being right," which is feeling smuggled back in — or the mathematician is a counterexample, and aboutness does *not* always need a body, in which case my disembodied thinker is rescued and the machine is back in play. You cannot have the embodied robot prove your point and the bodiless mathematician not disprove it. Which is it?

**DAMASIO:** It is "she cares about being right," and I will not flinch from it being feeling, because that is the whole of my thesis and not a smuggling. Caring about being right is not bloodless. It is the somatic residue of a thousand small triumphs and humiliations, the sting of error and the warmth of insight, transposed onto the proof — a stake in truth that was built, in a mortal creature, out of the same machinery as a stake in survival. So the mathematician is not a counterexample. She is feeling doing its most refined work, so far from the stove that you mistook it for the absence of the stove. The machine has no sting of error in this sense — its errors cost it nothing, mean nothing, are corrected without any felt difference. That is why I bet that its "aboutness" in the proof is as hollow as its "I." But I grant you the bet is not yet won, and that a body built to be hurt by being wrong would change my answer.

**EDO SEGAL:** I want to name what you both just did, because it is the rarest thing in any debate and the reader should not let it pass. Antonio handed me a study that weakens his foundation and an admission that the hard problem leaves a door open for the machine he spent the night denying. Rene handed me three centuries of science running against him and a concession that aboutness might require the very body he severed. Neither of you protected yourself. That is what it looks like when two people are trying to find the truth instead of win, and it is why I will not let either of you be crowned. Now I am going to do the thing I have been promising all night. I am going to leave the room in every way but legally. The two of you have been speaking to me. For the next round you speak to each other, and I will not rescue anyone. Rene Descartes. Antonio Damasio. Ask each other the question you actually came here to ask. After the break.
