So we ditch the philosophical puzzle and focus on the reality we can perceive and reason on. The problem is that consciousness is a philosophical invention (and a slippery one at that).
We're in the wrong frame. If you accept consciousness is a thing you end up in this weird tautological state - it's not special, but we've put it in a special category.
If you view via a grounded, practical frame, you probably don't care about consciousness. The fact that it's undefinable is probably a major clue.
I know for sure what I am perceiving. Forget about if it is a simulation or not: it is still what I am perceiving. There is nothing else I can be sure of.
So you are correct that it is, in some sense, un-explorable. However, if the above is the reason, then nothing else is explorable also; you cannot prove that we are not in a simulation, and in a sense it does not matter.
If you accept that we assume we are not in a simulation and the knowledge we have matters, then consciousness is also open to exploration, and it is not only a philosophical thing. There are several hard questions about consciousness that are meaningful in this frame:
- Why do some things appear to be conscious and other not so?
- Is there only one consciousness in the universe, or multiple?
- Is consciousness local and embodied, or not?
- Would restoring the physical substrate of consciousness (if possible) lead to the same consciousness, or an identical one? Does this distinction between "same" and "identical" consciousnesses even make sense?
Etc
These statements conflate, as idealists do, epistemology and ontology.
What we know "for sure" has no bearing on what's real. These are entirely separate questions.
What an ape might, or might not, feel certain (or any which way about) says nothing about where an ape finds itself. Of course, this is a great injury to our ego, and sense of power to determine the nature of the world by our mind alone -- but such is life.
The world is not human, not at all like a human, and nothing about it follows from us at all. The world is not made in our image. Consciousness is a derivative, secondary phenomenon which is a measurement process occurring in the body of an ape, and whatever it manages to measure with any clarity, has no impact on the nature of that world.
Can you define existence without depending on or referring to consciousness?
I'd consider myself a materialist (in the philosophical sense) and this is why (and I agree with the rest of your comment to)
We can not know, but in the absence of evidence to the contrary (e.g. someone metaphorically popping their head in from "outside" and revealing another layer to us), while it is important to understand that we do not know, it is more productive to assume in the absence of evidence, whether it is "real" or subjective or a simulation.
As long as it appears to us to follow consistent rules, we can explore those rules, and explore our apparent material reality.
You can explore how the simulation works, there's just some other layer you can't explore. Or maybe you can somehow.
When you look at the stars, are they real or a simulation in your brain? Does that mean you can't explore them?
This is unknowable.
This sounds similar to the "how do you know you're not dreaming?" question.
When you are in a dream, you really are the only single conciousness of that world. Any other person you interact with inside your dream is not performing any thinking of their own. Instead, dream interactions are just your single consciousness interacting with itself.
I think it is obvious there are multiple consciousness in the universe and not just one. Unless you're in a dream right now ;)
> I know for sure what I am perceiving
This reflects my view. And I’ve always found it mildly amusing that beings I cannot prove to myself are perceiving attempt to convince me that I’m not perceiving, when that’s exactly what I’m maximally sure of. Imagine arguing with an LLM designed to convince you that you’re not real. It would be weird, wouldn’t it?
That depends how it tried and what influences the LLM had on the outside world.
For example if the LLM could drug you, either by convincing you to take drugs, or trick you into doing it, then convincing you that you're not real becomes monumentally easy. Derealization can be a monumentally profound/terrifying experience to your psyche.
Who invented the words "consciousness" "reality" "fundamental" that you are now using? you are using language invented elsewhere while claiming you can't be sure of its reality.
Are you also claiming you can't be sure someone had to create and raise you to get to the point of asking such questions? We are downstream from parents and society.
The whole discussion here is anchored on individual level, but we are not viable outside society. It's like extracting one cell from one organ and saying it is mysterious why it is like that, while ignoring the organism and the evolution.
If society fails, human die too. If a human makes a fatal mistake, the cells in their body die too. We depend on top level doing its job to keep the lower layers viable.
Your senses are the only thing on which this statement rests. Your don't know anything like "language", "invented" etc. All you know is what your mind and your senses tell you.
And, yes, engaging with you on this topic, and my argument, is also included in what I refer to as my perception. I have no way to prove that you are even conscious, or that anything like language or invention actually are real, whatever real means.
Yes exactly. You are sure of nothing except the fact this now exists. The simulation could collapse in the next second. I could awake from this dream.
I cannot know objectively whether I am in a simulation or not. I can, however, reason about my experience, the experiences of others (as I perceive them), and the systems that facilitate perception. All of that information is logically coherent, so I can "know" it. My knowledge may not be objectively proven, but it is the most subjectively relevant conclusion.
It's one or the other: either nature is all there is, and therefore, consciousness is a purely natural phenomenon, that we can investigate, and probably eventually replicate, and can't deny to other beings or to machines upfront; OR there is something outside reality that we might as well call God.
I'm strongly in the former camp, but I don't have issues with the latter one. What upsets me is the inconsistency of those who try to support both ideas at the same time. They shouldn't be allowed to have it both ways.
Most philosophers are materialists or computational functionalists, while being monists. This means they aren't dualists, and it means they do not adopt the supernatural explanation. But they are careful not to rule out dualism.
There's this pattern I've observed in discussions about philosophy. First there's a rejection of philosophy as silly and misguided, followed by a rediscovery of the same concepts that philosophers have developed, but under a new ad-hoc and less precise language.
Congratulations, you're a philosopher.
These people believe this while at the same time considering dualism so ridiculous as to laugh dualists out of the room. The evident problem being that "mind uploading" is the most dualistic possible position to take. A real monist would easily see that by doing mind uploading you have just created a clone that is a whole separate entity from yourself and it is not yourself.
For example Searle's Chinese room thought experiment... On the one hand you can easily construe it to imply that he believes there's something fundamentally special about human consciousness that cannot be reproduced by a machine. On the other hand you could interpret his perspective, which I think is more in line with his real perspective, as implyimg that replicating the human mind machine requires truly replicating it physically rather than approximating it and that it's misleading to imply that you can get there with an approximation ... Still I can see how this confuses dualists or could appear in line with their point of view even though it is arguably a nuanced take on the materiallist view
Every guy saying that free will doesn't exist is arguing exactly this. Physical causality considered an obstacle to freedom implies that the conscious entity is somehow outside the physical world.
I do believe in intelligence (which is measured against a particular task) and ego (which inflates the self over the other).
[1] Or "qualia", to be precise.
[2] For example, the existence of qualia might require certain carbon-based structures which aren't present in silicon-based devices.
So there should be no reason we cannot reduce these phenomena to actual quantifiable and there for Computable elements.
To me, that idea seems entirely back-to-front. To me, it appears obvious to me that I am having a conscious experience from which the physical world and all its laws and processes, emerge. What’s even more interesting, is the narrative of that physical world. I am witnessing a physical world that is more often than not, trying to convince me that everything that exists has come from it - perhaps poetically in an attempt to ground (confine) me in it, grounding me in the belief that I am only alive inside the confines of what we call the physical world, where the truth is otherwise.
I simply don’t buy that my consciousness comes from my physical brain, it seems more likely that my brain comes from my consciousness - whatever that is.
I am not impressed with the idea that the conscious experience is special and is in need of explanation. Instead, I propose that the physical world is the more special and more interesting part, that needs an explanation. Not to describe all the physical laws and processes, but to explain why it exists at all. And that is done, not by distracting ourselves with searching the physical corners for answer, but instead by exploring the question of why anything would have given rise to a world like this in the first place.
And that, right there, is the truly difficult question, which is answered by peering over our shoulder into the abyss, from which we all had to run from to arrive here.
If the mind is supported by or comes from the physical world, then the hard question is "why is there something it is like to be me"?
If the physical world is supported by or comes from the mind, then the hard question is "why is the product of my thoughts sometimes incredibly malleable and other times not at all?"
From a pragmatic perspective, there are certain events that behave the same whether the mind came first and is somehow restricted in certain capacities, or if the natural world came first and is imposing itself on the mind (through whatever supports it).
For instance, falling down stairs is going to hurt in either case. If the physical world exists independently, that happens because you either are or have a body which is also subject to its laws. If there's a mental monism, that happens because you can't shape all your thoughts, and those thoughts you can't shape act on some other part of you in a way that injures what you think of as your body.
I think both positions (physicalism vs mind-first) suffer from the same issue that is to reach the bottom of it all, except physicalism seems to have reached further. In the past we wondered what the world was made of and we observed it, coming to the idea of elements such as Aether, then later developed chemistry then physics, reaching layer below layer of rules that interact to the emergence of the layer above. Lots of rules that we can (apparently) reproduce and verify, cells emerging from molecules interacting emerging from atoms interacting emerging from quantum particles emeging from quantum fields... Maybe emerging from strings or a simulation? We don't know. It seems to me we also don't know how to tell we've finally reached the bottom of it, but what we have sounds pretty solid.
In a mind-first view it seems that this stack is upside-down, with a consciousness giving rise to a brain in a world with its objects which are made of molecules coming to existence upon observation (that is, chemistry would be a top layer after conscience further inspecting it), which are ruled by physics etc. Except this cause-and-consequence relation is not clear to me. Like you said:
> To me, it appears obvious to me that I am having a conscious experience from which the physical world and all its laws and processes, emerge.
How would this work if, from your perspective, I'm also conscious and not a p-zombie? Do I give rise to the world, or do you? Do we all collectively create a single world from our consciousness in a "Sandman's Dream of a Thousand Cats" way? And if we're all p-zombies except you, why bother arguing with us? (not throwing shade btw, I'm just interested in your point of view).
To me physicalism looks like a flame graph with physics at the bottom and minds at the tips of the flames, with less simpler things giving rise to multiple complex things, while mind-first looks like an icicle graph (assuming multiple consciousness) or an upside down triangle (assuming a single consciousness), with physics at the top (all "graphs" putting cause at the bottom and effect on top).
Don't worry. You're in good company.
> How would this work if, from your perspective, I'm also conscious and not a p-zombie?
It's impossible for me to say that you are conscious. I only watch my own movie. In that movie, others appear to be watching their own movies. Their movies exist only as content in my movie. I cannot say for certain whether or not there really are conscious experiences like mine occurring. All I can say is that I am being given the impression that there are.
> Do I give rise to the world, or do you?
I do. Or at least, something impresses the world upon me. You are a feature of the world that is impressed upon me, and, disappointingly (for me at least), there's no way to confirm it through this movie that I am watching. I am left having to "make up my own mind" about whether or not I choose to believe you are anything but a p-zombie extra, in what is (as far as I can see of the conscious spectrum I am able to perceive), a single screen, single reel movie. But I'm just guessing, hoping, wishing, because that's all I can do from this limited vantage point.
> Do we all collectively create a single world from our consciousness in a "Sandman's Dream of a Thousand Cats" way?
It's a cute idea. Design by committee. Books/predictions of the future seem to have this annoying property of becoming true, lending to this idea. Who knows?
> And if we're all p-zombies except you, why bother arguing with us?
What else am I supposed to do? If you have unimaginable wealth, infinite time and the ability to conjure anything into existence, exactly what are you to do? Perhaps you might dream up what having the opposite of your existence might be, and set about convincing yourself that you are a time-ful, perishable human-being bound by physics and inevitably limited by the finite energy available in the universe, stumped by entropy. Perhaps you even role play as the puppets on the ends of your fingers, while convincing yourself that they're just as real as you are, so you can feel what it's like not to be the majesty of your own lonely empire. What else am I supposed to do, than to go along with it? If we destroy the illusion, we're back to square one - and then what?
Cool, I'll give you some drugs that alter the physical reactions in your brain and turn off your consciousness, then tell me all about it....
oh.
In my experience, the majority of people who take the position that consciousness is something special to humans are nearly always coming from a religious background and viewing it through a religious lens. This makes sense, as if we reduce consciousness to physical reality, then the implications to free will become quite clear and devastating against it being a thing. This essentially destroys a lot of religions which are fundamentally based on humans having free will. Detailing the full chain of thought would take quite a bit of space, but the quick answer is that the ability for free will is hiding from us if it actually exists. Many people reach for quantum mechanics and its source of randomness as room for consciousness to exist that gives us free will, but the problem there is neurologically we operate at a far larger size than quantum effects would be measured. There's also no way to control the outcome of quantum events as it is truly random. So one would need to show how our neurological physiological minds could manipulate quantum space, which of course they can't. At the level our brains operate, we are well into deterministic physics.
While they absolutely deny this, the impression I get is that they are making a god of the gaps argument. Consciousness is something we don't understand yet, and can't even really define well as many people here have pointed out, so to them it doesn't feel like a classic God of the gaps.
For that reason, I find your comment above quite interesting. I personally find philosophy to be a fascinating and useful tool, but it definitely has a tendency to mislead, especially in areas where hard science can inform. Of course there's an entire debate around the philosophy of science itself, but that feels off topic here.
Like, that may have been your experience -- not contradicting you on who you've met and what you've talked with them about etc. ... but what he's talking about is a position argued by a lot of philosophers and including those who have no particular metaphysical commitments.
Rovelli here does a lot worse than Dennett's "quining qualia" paper where he tries to get people to be really specific about "what are these qualia like" and finds that they're so hard to embed in language, to symbolically represent, that maybe he-as-philosopher can discharge his duty to be engaged-with-phenomenalism by just kinda sticking his fingers in his ears and saying "what phenomena?! you haven't clearly defined the phenomena!"
But someone like Searle who has no bones about himself being an atheist and, while he didn't like to describe himself as "materialist" because of the history of that term[1] he would acknowledge that it was close to his basic position. And I want to be clear that he views consciousness as a scientifically solvable problem. He doesn't think we've solved it yet but he thinks the philosophical problems are ultimately tractable and if we solve them and get out of the way you'll get a fine science of consciousness someday. Nevertheless, he's very clear about agreeing with the fact that these qualia are important to the discussion and he would laugh at you for trying to leave them out -- he'd say, now you're trying to make a science of consciousness, by leaving out the consciousness. And of course you don't think there's any science left to be done at that point and "well, it's all deterministic physics, we understand it all, nothing to be done here."
So like if you want to read his take, a book is Freedom and Neurobiology, but for this comment I just want to point out that him simultaneously believing that there are phenomena of experience, and believing that there is no God, are two beliefs that are not uncommon for philosophers to hold together.
1. There's kind of no way to very briefly make the point since you kind of need to be hit in the face with a sledgehammer about it. So Searle views Descartes as erroneously trying to package up the world into two realms -- mind properties or substances on this hand, physical properties or substances on that hand -- and insisting that they can't overlap. And then Descartes' legacy was that you had camps which said 'those mind properties aren't real, only the physical properties' (materialism) and 'those physical properties aren't real, only the mind properties' (idealism) but coming from the same mistaken beginning. Searle would point to the score of a football game and say 'now is that physical because it's represented in terms of lights on the scoreboard, or is it mental because it's represented in terms of the thoughts of the referee, what about all the people on both sides who think the referee made the wrong decision -- something which, remember, by definition the actual referee cannot do; they are the final authority -- and they believe that the score is "really" some other number distinct from the score represented on the lights; and what if none of these people are "right" in the sense that if a perfectly perceptive model referee could have made all of the scoring calls in the game according to the rules on the books, then the score would have actually included an event that everyone watching thought was unambiguously non-scoring but actually it was completely legal and valid. But here I-the-philosopher come into all of this absolute mess and I want to carve out a clear boolean yes/no classification, mental vs physical, material vs ideal, which is it -- the problem, was not that I counted to two distinct possibilities, but that I thought counting those possibilities was a meaningful way to decompose the problem in the first place.
But you can view consciousness as a natural phenomenon without being reductionist. In a Hempel's Dilemma-like turn, you could say something like: "consciousness, like mass, is a property of arrangements of matter and exists wherever matter is arranged in a particular way. Disrupt the arrangement, as with anesthetics, and the consciousness goes away."
You end up with something like integrated information theory: https://iep.utm.edu/integrated-information-theory-of-conscio...
From such a perspective, the article's byline, "Consciousness is not separate from the physical world — our “soul” is of the same nature as our body and any other phenomenon of the world", is true. Like mass or charge, consciousness is merely another property or feature of stuff of combinations of matter that exist in the physical universe.
But there's still a "hard problem of consciousness" with such a theory. The distinguishing feature of qualia-like consciousness remains: it can only be properly verified from the inside. Researchers may devise theories that say "if property X holds, then the lump of matter is conscious" (like Tononi is doing with IIT). And the theory they develop may be quite tight - for all actions where it predicts temporary loss of consciousness, people exposed to the experiment say "I wasn't conscious at that time". But until they can solve the hard problem - being able to detect the what-its-like from the outside, the hard problem remains.
Though, as you're saying, if you just want something that predicts observable outcomes, then consciousness theories that say "this anesthetic-like thing produces what, to the outside observer, is indistinguishable from loss of consciousness", might be good enough.
If we create a machine that is able to print on the terminal 'I feel pain', how do we know when to believe the machine is feeling pain?
This isn't enough:
Is a very complicated set of matrix multiplications enough?Even if the memory hardware is replaced, it won't be the 'same' individual, no? Would an aversion to 'death' be rational in it?
Philosophers may squint at the suffering-in-itself long and hard, but I doubt they'll affect waking/extinguishing empathy of the masses. Exploring the suffering that fails our empathy (e.g. suffering of a wheat plant harvested) seems a highly abstract task; more abstract than high mathematics.
Some philosophers believe that our human emotional connection to redness is special. These are the people talking about qualia. My belief after much reading is that it is not special. I /do/ believe that the human ability to tie our senses so deeply together synthetically and into our emotional and memory is special. My robot cannot write a poem about how the redness of a flower reminds them of their mother’s funeral. But now we are talking a matter of degrees, not qualia.
whether or not matter was continuous and could be divided forever by repeated halving, or if there were "atoms" was a philosophical puzzle more than 2000 years before "we" found the answer. That it was "atoms" was one of the 2000y.o. hypotheses. same with dividing time and distance. It's ridiculous to dispense with good hypotheses.
we know that consciousness exists before any other thing. We don't even know that the so-called physical world actually exists, only that we we consciously think we observe it, but we can wake up believing dreams or psychotic imaginings. How can you enjoy watching The Matrix, and yet walk out so smug about you knowing the answers before they've even been found?
I personally do not believe in the material universe. All of our theories and descriptions and empricism about it proves that it is mathematical only. All that exists can be (and is) explained by math (and perhaps some computer science in the sense that there is state, and math doesn't require state) I call upon rational STEM types to reject the material universe the way you wish to dispense with consciousness. Consciousness, like math, is immaterial, and we have more evidence for immateriality than we do for materiality. When our hypothetical hands touch each other in a handshake, you would even point out that on a quantum level, nothing touches anything.
The "inner experience" might be totally optional to fitness, like green eyes.
I think evidence suggests that humans aren't conscious most of the time. So it wouldn't surprise me if 95% of the time people are just stochastic parrots. But maybe that number is even close or equal to 100%.
Intellectually a lot of humans perform worse than LLMs and a lot of people (most of them) are completely unable to process abstract concepts and basic logic at all. Can those people truly be called conscious? Is consciousness worth something without the ability to reason?
Does that mean when a boxer is knocked unconscious we should call a philosopher to fix it?
You can derive consciousness as a somewhat obvious conclusion of empirical study of behaviors, we have multiple fields of study that lay out cognitive function and criteria.
I'm always mystified why consciousness is so often claimed to be undefinable.
How can you say that?
It would be very interesting to know how to build robots that love their work, versus ones that hate their work. Not because it makes a practical difference to us, but because of ethics.
"The Moon" is a philosophical invention, and yet The Moon is a natural phenomenon.
There is no such need. If we view the idea of consciousness as a childish delusion and suppose that no one has consciousness at all... that we are animals with behaviors that explain all the actions we take, we can model the world just as effectively as if we are the vessels of marvelous souls that are inexplicable and magical.
Theology was the traditional venue of these absurdist arguments about how many angels can dance on the head of a pin. But at least they had an excuse, they never pretended that it was science or that the debate was grounded in anything other than religious belief.
It doesn't contradict anything. It simply means that there is a gap in our current understanding, which may (or may not [1]) be scientifically explained in the future.
The default reflex of the opponents of "the hard question" (i.e. those who deny the existence of such a question) is to attach a religious or spiritualist meaning to it, which is far from the truth. It's a question that arises from scientific curiosity that we hope to answer one day.
[1] The "may not" part does not imply that there is something magical or metaphysical about it. There are things that we may not ever answer, like "do parallel universes exist" or "was there another universe before the big bang".
a) it is wrong to say definitively that it is untrue. there is no acid test for the existence of God nor of spirit.
b) religious and spiritual traditions have wrangled with this very question for at least 3000 years. it is not a 'scientific curiosity'. It is one of the most fundamental questions of human experience.
b) This being a fundamental question proves scientific curiosity. We wouldn't have achieved current technology if not for scientific curiosity.
I'll admit my position was built not to explain the hard problem of consciousness, but to find a philosophical answers to animals and newborn reactions to the mirror test, but I found it satisfactory enough when I heard about the hard problem of consciousness. My main argument for it is not an attack, it's simply Hanlon's razor. If you find a simpler explanation that doesn't demand new understanding, I will listen to it, if you do not, you have to show me the simplest solution is wrong, and I'll go to the second simplest.
If science can in theory explain consciousness ever then it’s an easy problem.
Like I said if science can explain something then that by definition is an easy problem.
Whether or not physicalism has any hope of succeeding depends on whether there is a further conceptual or explanatory insight that when added to the standard structure and function explanatory framework of science, will ultimately bridge the gap. Who knows what that might look like. It's certainly premature to render a verdict on the possibility of this. But it should be clear that a full explanation in physical terms will need some new conceptual ideas and so the problem of consciousness isn't merely a scientific problem that will dissolve in the face of more scientific data, but a philosophical problem at core.
People want to be talking about whether AI suffers in a morally meaningful way. In non-human animals this debate is often centered around the question of whether the animal has conscious experience, because there's little doubt that much of the emotional and experiential systems are shared.
The analogy goes wrong with AI, where definitions of "consciousness" would seem to apply in the sense that the model clearly has a category for itself in its world model, feeds back on its output, etc. However the analogy between how it works and anything we would recognise as emotion or suffering is extremely strained.
The solution is to just focus on ths question of what we really mean when we think of morally relevant suffering. It's a much clearer question than "consciousness" and it sidesteps the problem.
And, of course, if they disagree with me about this and want to claim that they are, in fact, conscious, I'm not sure they can do that because... well the hard problem of consciousness.
Creatio ex nihilo.
> consciousness?
Ditto. It's actually the same question.
Great, I'm a physicalist so uhhhh I reject this lol. I think you can define cognitive capabilities and phenomenal experience by reducing to structure and function. You're right that it's simple though.
But the process of reduction starts by precisely defining the phenomena in terms of structure and function. If we are unable to give a precise definition that uncontroversially captures the target phenomena, then we cannot in principle give a scientific explanation of said phenomena. This is where we stand with consciousness. There is an in principle barrier to a transparent structural description of phenomenal consciousness. But this is an explanatory limit only. It doesn't necessitate some non-physical phenomena is involved. What we need are new concepts that can connect the phenomenal to the physical. But conceptual innovation is not something you get from more measurements and more data. This is what makes consciousness a philosophical problem.
Yes, reduction would be one very viable strategy. It doesn't require precisely defining the phenomenon in order for me to just say that it reduces based on the fact that reduction has been a successful approach for everything else in cognition.
> There is an in principle barrier to a transparent structural description of phenomenal consciousness.
Yeah this is what I reject. Why do you say that this is in principle a barrier? You're discussing it as an explanatory gap, not in principle.
To draw a parallel with physics, about which we as a society (and me as an individual) know a lot more, we are gonna define mathematical objects and laws whose behavior maps well to certain subsystems of the brain that we ourselves have defined. Physics had it easy in this sense: it turned out to be remarkably simple to describe the universe to a great degree of precision. Still, we all recognize that the physics mapping we have to this day isn't perfect; and it's even possible that it will never be perfect. It may be fundamentally impossible to reduce some systems to simpler mathematical objects which we can reason about. It does seem to be generally possible, however, to find a reasonable approximation. This again is what I think Rovelli's point is about: science is the process of finding a good approximation which has predictive power. And what is there in the brain that's fundamentally so different and that we're never gonna be able to explain? Why does everyone keep insisting that consciousness is special?
I do agree that that only when (if) we do get the accurate mathematical description, then we're gonna be able to properly discuss the hard problem. But my hunch is that once we do have all the tools it will just dissipate from scientific discussion, similarly to how the measurement problem in quantum mechanics is slowly undergoing the same transition from "this is a fundamental problem" to "we were just asking an invalid question due to misunderstanding and old ways of thinking". Obviously I have no proof of this beyond intuition, but I more or less agree with every sentence of this article, and that shapes my intuition.
> A philosophical zombie would claim to know what subjective experience is; otherwise, it would be empirically distinguishable from a human. Chalmers’s point is that the existence of the hypothetical, irreducible consciousness of which he speaks is something we can be convinced of only by introspection. During introspection, physical processes in my brain convince me of my consciousness. The same would theoretically happen in the zombie brain, convincing it of having consciousness as well.
And this is why illusionism is not a satisfactory explanation. "Convincing it". Who is being convinced? Who is experiencing this?
Imagine the easy problem of consciousness is solved: we understand the brain at every scale, from ion channels up. We can draw up a complete account, at every level of abstraction, of what goes on in the brain when you see and "apple" and say apple, and trace the signals across the optic nerve, map those signals to high-level mental representations, explain how those symbols become trees in a production rule which become words which the motor cortex coordinates into speech, etc. We can map every "pixel" of the visual field at any time t.
Now imagine you take this description and rewrite the labels consistently, and show it to an alien. And they see this very complex diagram of an information-processing machine and they're not sure what it's for. And they'd think it's as conscious as a calculator, or a water integrator, or a telephone network, or the futures market of the European Union.
Either all the computation happens "in the dark", as in a calculator or an Excel spreadsheet or a slide rule or Factorio, in which case we are p-zombies and consciousness is an illusion, which contradicts every waking moment of our experience (since consciousness and experience is all that we have); or, everything is conscious, from brains to slide rules and spreadsheets, and that is incredibly, and also has a number of problems (e.g.: why aren't my neurons individually conscious? Why does consciousness stop at my skull, that is, why is the causality of signal-trains in neurons more "conscious" than phonons in the hydroxyapatite crystals in my skull?).
That's the hard problem.
You are still presupposing the premise here, in multiple ways:
1) "My experience is that I'm conscious, and math cannot result in consciousness, therefore consciousness is a separate thing." Question: who says math cannot result in consciousness? Do you have empirical proof of that?
2) "We have solved the easy problem of consciousness, we know exactly how the brain works" implicitly assumes that the formation of consciousness is NOT among the things we've learned while mapping out all features of the brain. This, again, is not an assumption that's supported by anything than wishful thinking.
And, further:
> or, everything is conscious, from brains to slide rules and spreadsheets, and that is incredibly, and also has a number of problems (e.g.: why aren't my neurons individually conscious? Why does consciousness stop at my skull, that is, why is the causality of signal-trains in neurons more "conscious" than phonons in the hydroxyapatite crystals in my skull?).
"Some math can produce consciousness" does not mean "ALL math HAS to produce consciousness" does not mean "EVERY PART of all math has to BE conscious."
Of course it's hard to define consciousness if the implicit definition is "certainly not anything that I don't like." The hard problem of consciousness is only hard because the default human move is to _make_ it hard.
If the answer is no, then I'd ask if a gorilla's consciousness is fundamentally different than a baboon's? I think that answer has to be no by definition, assuming the first answer is no.
And so on, until we get to where a human's consciousness is not fundamentally different than a tube worm, just a continuum of degrees.
I'm not sure what to draw from this. But whenever I read something that speculates on the nature of consciousness, I always try to look at it through the lens of the human-to-tube worm scale. Does the argument survive a continuum, or does it depend on human consciousness being fundamentally unique in some way?
I guess you could argue that even though there's a continuum, consciousness effectively hits zero somewhere around reptiles. Sort of like how technically I feel Alpha Centauri's gravity, but effectively it's zero. So in that case, the argument only has to survive mammals to say corvids.
IMO consciousness is something that appears when you have enough "brain power" to spare, maybe as some side-effect of some evolutionary trait. I'm no expert and it's a very simplistic explanation, I know, but in general I tend to agree with the general idea exposed by Rovelli in the piece: consciousness is just a manifestation of the real world of which we are part, just one very complicated and that we are not able to understand (yet?).
Note that at least one species of fish have been shown to very consistently pass the mirror test (they try to clean up a mark on their body they can only see in a mirror, then go back to the mirror to check, and repeat a few times). So, at least if you consider the mirror test to be a sign of consciousness in animals, then you might want to extend this to at least all chordata.

At least the answer to this is simple:
'fundamentally different' is not a transitive function
:-)
A lot of people, myself included, have the intuition that thinking that this might be possible is a sort of type error, to put it in CS terms.
A bit like asking "Have you proven that ice cream? Are you sure maths can not prove that ice cream? Do you have empirical evidence?"
Asking for empirical evidence seems beside the point, since the issue is a logical one.
Which math? Why some kinds of information processing and not others? If all information processing leads to consciousness: why does consciousness stop at the boundary of the brain? Why isn't every neuron individually and separately conscious? Why not the two hemispheres of the brain? Why isn't every causally-linked volume of the universe a single mind?
> Implicitly assumes that the formation of consciousness is NOT among the things we've learned while mapping out all features of the brain.
The point is that it's not clear at all what empirical knowledge we could acquire that would explain consciousness. Is in: what is the shape of the answer, and can a collection of material facts about the world have that shape?
> Of course it's hard to define consciousness if the implicit definition is "certainly not anything that I don't like." The hard problem of consciousness is only hard because the default human move is to _make_ it hard.
This is just a tiresome ad hominem. I want to be a materialist and an eliminativist. I would like this to be simple!
Consciousness isn't something the information processing has, it is something the information processing does. It's a function, not some magic property that happens on top.
Consciousness is simply your brains ability to figure out what part of all the sensory input it gets can be attributed to the "self", just like other parts might be labeled as cats, dogs, table and chairs, some will be labeled as self.
And I am sure one day somebody will boil that down to some nice math, since fundamentally it's about networks. If the brain wants to move a hand from one spot to another, that's easy if it is its own hand, a couple of nerve impulses and it will happen. If that hand belongs to somebody else, moving it is a whole different ballgame. That fundamental different in connectedness should be expressible.
It's special pleading. What empirical knowledge you could acquire that would let you understand a tesseract? There are many things that are difficult to understand.
To anticipate a possible question about my definition: I don’t have a strict one. I’m almost completely with Rovelli on this one. I think the day we find a proper definition of the concept we’ll have done the first step is solving the (one and only) “easy” problem of consciousness. But I’m open to hearing your own definition since I feel like I just can’t grasp your concerns. I must be missing something.
What about this: - this class of brain circuits are not not firing when the person is (unconscious, in deep sleep,a newborn/animal obviously just directly responding to outside stimuli), while obviously active when a person performs conscious activity - this class of brain circuits does not exists at very primitive species and is progressively more developed the higher the evolution chain you go
Did you actually read what you just responded to?
The hope for resolving this, I think, is that once we understand all processes in the brain, there will be some process that clearly is the self-referential "person" that is produced by the brain in normal operation. Anesthesia is strong evidence that there is some physical process that is the person.
The hard problem only really needs consideration if we get to a point as you describe, where we fully understand everything happening in the brain and cannot assign consciousness to any part of it, even though we can turn it off and on again (e.g., with anesthesia).
Yes. I think it's possible with sufficient understanding, the hard problem will dissolve.
But, the question we can ask today is: what kind of explanation would explain away the hard problem of consciousness? What is the signature the model must satisfy? I don't think there's a good answer to that.
I think that is a question more about the people to whom you are explaining the solution to the hard problem of consciousness. The natural tendency (as with 'what is AI?') is to say 'ah, but that is the easy part, the hard part is <some other thing that they feel you have not explained properly>'.
Not really, it only suggests that the brain function is involved in some way. If the brain is an “antenna” anesthesia could prevent it from functioning and that would be a totally consistent theory.
Also, the emergence of a consciousness like illusion kinda follows from an evolutionary perspective. To survive, a "calculator" brain needs a model of the external world in order to predict how it will evolve and to act in ways that improve survival odds. Once such a model exists, it becomes almost inevitable that it also includes a model of the system itself, since the brain is also part of the world it is modeling and an agent within it. This self-referential loop is likely what we experience as "consciousness" and it becomes central to how we understand and navigate reality.
If we accept this framing, many traditional paradoxes dissolve on their own. The problem stops being "hard" in substance and becomes hard only in terms of imagination.
But why a spreadsheet simulating the brain, and not just a spreadsheet doing normal financial math? In other words: why are some types of information processing "privileged" to create phenomenal experiences, while others run "in the dark"?
> Also, the emergence of a consciousness like illusion kinda follows from an evolutionary perspective.

But this is A-consciousness, not P-consciousness. Which gets us back to square one: why does information processing give rise to experience at all?
who is eluded? people absolutely love this answer and give it constantly, not realizing that it's begging the question. in order for their to be an illusion, there needs to be someone to perceive the illusion.
It's actually a different question (sometimes called "the even harder question" or "the vertiginous question"), but if you have ever asked yourself the question of "why am I me and not someone else", the gap in our understanding of consciousness becomes clearer.
To use the same example: If there was a spreadsheet simulating every neuron in my brain, which one would be "I"? The original "I", or the spreadsheet?
Note that this question becomes meaningless if you change "I" to something else, so "both would be me" is not a valid answer. There is only one "I" (since I can't be experiencing the world from two sets of eyes, one organic and one spreadsheet-eyes, simultaneously), so I have to choose one of them.
The logical answer is that this spreadsheet, supposing identical mechanical processes - inputs, outputs, stored data - and I would both be convinced that they're "me", and they'd both be correct in that they'd both be something that functions, and therefore thinks, acts, and experiences things identically to me. Two different processes on different hardware running the same code. The concept of "ego" is a result of this code. To me, I'd be "me" and the spreadsheet would be "a copy of me". To the spreadsheet, it would be the exact opposite.
Of course, that predisposes that the software isn't hardware-dependent. But even then, I wouldn't discount the possibility of an emulation layer.
It really isn't hard once you accept that we're not special for being able to think about ourselves.
Materialism directly implies no-self and Advaita Vedanta schools of thought.
To your question, the answer is similar. If we remove this limitation of intuition, there doesn't seem to be a real paradox. Both you and a spreadsheet-like copy of you would each claim to be the real you, and from an outside observer's perspective, there is no contradiction.
I think the question remains meaningful after substitution: why a giraffe is a giraffe and not an elephant? Likewise "both giraffe and elephant are elephants" is not a valid answer.
What makes the computation in the brain special from other physical processes to give rise to this illusion?
The sewer system in NYC is complex. Does that also have the same illusion? Does the sewer in NYC have consciousness?
But if we built a Turing complete, sewer-like system that simulated every neuron in a human brain, it will claim that it is real and conscious for sure. There's no paradox at physical level, intuitively conceptualizing it is the "hard" part.
Why exclude the option that only specific kinds of computations are conscious, e.g. recursive control systems?
1. This requires explaining why only some kinds of information processing are privileged to be conscious, which seems rather arbitrary.
2. There's the question of levels of abstraction. Which information processor is conscious? The physical CPU, the zeroth VM, the first VM, the second VM, etc.
3. And there's the question of interpretation. What is computation? A CPU is "just" electrons moving about. Who says the motion of these 10^12 electrons represents arithmetic, or string concatenation, or anything else? The idea of abstract information processing above the bare causality of particles and fields is in itself a kind of dualism (or n-alism, because Turing completeness lets you emulate machines inside machines).
The 'where is the consciousness' question is interesting but not really a hard problem. The issue can be solved by being clear about what purpose does consciousness serve then locate where that need is realized. Consciousness is about information integration and broad access as a substrate of decision making. Recursive integration identifies the where. But thinking in terms of nested VMs is sort of missing the point. The point is to trace the flow of information and find the points of broad integration. This may involve multiple substrates. Identifying a single thing as being conscious is a mistake. The consciousness is the most narrowly specified causal dynamic that grounds the information integration.
Makes no sense to me, to me if a simulation of physics gives rise to consciousness that’s pure physicalism
Illusionism does say that there is a conscious experience. So illusionism is convincing to many people who have conscious experiences.
The alien would be able to look at the computation and describe the conscious experience it has.
You could put human consciousness on an excel spreadsheet and it’ll still be conscious. Even Chalmers accepts a simulation would be conscious. So no that’s not a. Argument for p-zombies. Even people that use the pz argument don’t think that pz could actually exist.
But your conclusion is right, the simulation example does suggest that the consciousness in the hard problem doesn’t exist. Which just leaves the consciousness you experience explainable by easy problems. Which is the illusionist position.
Edit: and the hard problem isn’t just why there is consciousness. But why consciousness is impossible under physicalism. So in your post you are just actually referring to the easy problem of consciousness when suggesting it exists.
Your aliens don’t know what it’s like to be you. But if these aliens decide to use your blueprints to print out a human, and the human says “ouch”, is it still the hard problem? This is what I don’t get.
Of course the music is different than just reading the score. A description of a process is not the process itself. We cannot know what it is like “to be” a bat but we also don’t know what it is like “to be” a spleen cell. Or the European futures market. Or a colony of ants, or the United States. These processes are complicated and intelligent, though not generally thought of having qualia. But I think it is only our hubris that differentiates the experience of an individual organism from that of our subsystems or supersystems.
How do you know that they are not? Any subjective experience they have does not have to overlap with yours. (same with your skull, skeleton, or any other subset of your body).
(for me, having slowly become more aware of the distributed nature of my brain, I'm not even really sure there's only one consciousness in my mind!)
On the other hand, "consciousness" concept might be as much useful for modeling thinking as “the four elements” for describing anatomy (not useful at all)—and we create better models eventually.
Carlos Rovelli has failed to understand the arguments for dualism, and is proudly sure that they must be nonsense.
If there's ever to be a "solution" to the dualism/materialism argument, it cannot possibly end in a "slam dunk" where it turns out that one side or the other was simply nonsensical.
IMO, the problem is actually one of epistemological framing. If I ask what "I" know, assuming that my internal experiences are the basis of my knowledge, then I can't accept materialism. But if we ask what "we" know, as a society of scientists and philosophers, together we find only natural material, and no evidence for dualism.
(It's like the prisoner's dilemma. What's best for me is to defect. What's best for us is to cooperate.)
Huh, evolution vs. creationism, many arguments happened over many years, yet one side was simply nonsensical.
> if we ask what "we" know, as a society of scientists and philosophers
That is how science is done; if you reject that approach a priori, no wonder your conclusions become unreliable.
If you want to see an obviously nonsensical world view, you need to look at something like the Time Cube "theory". Rovelli is essentially claiming that dualism is more in this area - which I agree with the GP is quite unlikely for such a long discussed and influential philosophical idea.
Map the process by which you learn that you have experience. Then determine if this process works correctly. Alien needs to learn to code; they have difficulty, because they try to learn integrals without arithmetic and algebra. Before you can solve a complex problem, you should first train on easy problems.
For us, sure; why would it be so for them?
Crows don't seem to be particularly upset by strutting around naked and eating bugs from the dirt.
The guts' idea of a horror story, if it has one, may be more like indigestion or norovirus.
Maybe the literary creature shoe should have started on the other foot, and sent us in search of proof that we are or are not p-angels. That at least puts the burden of proof on the compatibilists where it belongs.
I don’t know why this is a block in philosophy let alone computer science. We experience it frequently and have a fundamental theorem about it.
Plenty of movies about it as well like the Matrix.
The author takes a blurry position between non-dualist naturalists like John Searle and eliminativists like Dennett and the Churchlands and doesn't seem to engage with them at all, much less probing into the issues with those views that might motivate people like Chalmers and Nagel.
It crescendos with a hand-wave:
> The mind is the behavior of the brain, properly described in a high-level language. Neither my own experience of myself nor an external experience of me is primary[.]
A number of views about consciousness are compatible with statements like that (like the ones above and many others), each with their own philosophical tradeoffs and bullets to bite. The author seems generally unaware of them yet somehow confident that they've solved the matter.
Scholastic philosophers taught that body and soul were two components of the SAME entity, the human being, and that both were good because they were created by God. One good essence with two components, in other words. And while they claimed that the soul component was immaterial, that absolutely did NOT mean that the soul was not part of the natural world. To claim this is to seriously misunderstand their view of the physical world. To them, matter was only one component of creation.
The strict mind/body dualism was not introduced by medieval Scholastics, but rather by the advent of modernity in Descartes, and developed further by Kant and other enlightenment philosophers. In other words, this is very far from being a medieval problem - on the contrary, it a problem created by modern philosophy.
As for the author's equation between subjective experience and qualities of things, or his equation of processes in the brain with the mind itself, this just ignores the facts. Qualities we observe in nature are obviously distinct from the feelings they produce in us in many cases (beauty, sublimity, injustice, etc. produce distinct feelings like reverence, humility, anger), and if the mind were equivalent to brain processes, then certain powers of the mind that we obviously have would be impossible (such as our ability to reflect on those very same brain processes in ourselves).
I still don't like this new trend of dismissing the hard problem altogether. We really don't have an explanation of phenomenal consciousness—it might even require novel physics to explain! [2]
I'd also like to point out that, though this might seem like a semantic argument, it has meaningful consequences for how we approach science and ethics. [3] For example, if we are physicalists and accept that phenomenal consciousness is a property of the world, what does this tell us about other unobservable properties of the world science may be missing? (Recall that we only know about phenomenal consciousness through our own experience of it; we cannot observe it in others)

I'm almost convinced that those who deny the metaphysical (or, if you insist, the plausibly merely physical) force of qualia are philosophical zombies trying to persuade us against the existence of the most obviously true piece of knowledge we have! Or, more generously, they are so steeped in the premises of modern empirical science that they treat their fundamental phenomenal experience as so untrustworthy as to be disregarded, despite its actual necessity in employing those very premises.
Poor, disregarded qualia! Oh that the scientists could see how much they owe to you.
Basically it flipped the problem on its head. We're arguing how you start at the physical substrate and get to consciousness. They argued that you could start with consciousness and argue how you get to the physical side (experimentation via your conscious experience, etc). It was from a religious individual who called the conscious experience God and went further into how we all share this sliver of godhood.
Does anyone who knows philosophical "camps" know the terms for what I'm trying to remember? I guess I've leaned "materialist" for most of my life, but what other common philosophies (as in the academic discipline) are there?
There is not much you can show against the "there is a single existing soul that has many different persons (as opposed to each person having a different, personal soul) that dreams about the 'physical' reality" hypothesis except "I don't think my imagination is that good", really.
Well, you gotta spend the eternity somehow, so maybe the soul just got bored and started inventing miserable experiences for itself.
Yes, it's ridiculous.
https://en.wikipedia.org/wiki/Subjective_idealism
Consciousness is inherently about awareness, so at some point the consciousness would be aware of itself. Now it has the concepts of before/after, and from that opposites, incrementing, subtracting, 1 dimensional space etc. Eventually through this process you could "spawn up" other consciousnesses each expanding their individual bubbles of experience and understanding, eventually getting complex enough to create an entire universe with physical matter that can be experienced by other consciousnesses.
1. Whatever you believe is true is true (this is how the consciousness builds worlds before there is any physical existence)
2. Our consciousness built the physical world and runs it like a simulation.
3. The reason our minds and consciousness are highly correlated to the physical situation is to make the simulation feel real. It's a specifically designed feature that to a large extent synchronizes the "host" and the simulated objects so that despite being outside of the simulation, the "host" feels like they are inside the simulation.
4. The corollary to 3 (and 1) is that if you are damaged or die in the simulation, that effect is mirrored outside the simulation too (to some extent).

(Never thought my adventures in metaphysics would be useful in a HN discussion thread!)
Let us assume there exists in our planet an undiscovered island that has developed independent of other human societies. This is not an island of primitives. The inhabitants pride themselves on their scientific and empirical approach to knowledge acquisition, however they are not quite on par with the rest of the planet in terms of scientific knowledge and technology. Specifically for our purposes, they have not yet discovered Electro-Magnetism.
Now assume somehow (via a shipwreck, or whatever) these islanders come into possession of advanced transmitter/receiver communication devices, and we'll assume they are in working condition and have some sort of power source (magical internal or solar or whatever - they can be turned on).
As the scientists on this island fiddle with these boxes, they notice that certain configuration of the device interface will cause it to 'emit voices, songs, and music'. Various knobs seem to change the voice, etc. Further experimentation and they discover that speaking to the device under certain configuration seems to establish a sort of 'communication' with the box. After these blackbox approaches, they start taking apart these mechanisms (while they are turned on). Now let's just pretend the internal radio communication components are perfectly modular (in terms of functionality) and can be removed and put back as required.
They systematically begin removing various components and noting which uncanny features of these mystrious devices cease to function. One board removed and they no longer get certain band. Another board removed and the box doesn't talk back (think CB). They meticulously map out all these component to function mappings. The results are indisputable: These boxes are some sort of 'thinking machines'. The 'brains' of the machanisms is isolated to the radio elements of the devices. The 'proof' of this is that the boxes cease to speak or respond to communication when these elements are removed.
> consciousness can be damaged when it's physical container is damaged
Just like those radios.
This kind of simplicity is a very deceitful on, because it offers to seem to explain everything with nothing, and having phrased nothing in pleasant-sounding ways, concludes that this simplicity is a virtue.
Yes, and it is trivial to prove. One second lapse of attention and you could get bitten by a snake, or run over by a car. If the top level (consciousness) fails, the neurons die too. Cells depend on this centralized decision point to exist. There is no way to have humans without consciousness because ... they would not be able even to put the thing into the other thing to make more of us without it ... excuse the language, but the argument is solid.
They espouse consciousness or subjective experience is fundamental and contained in all matter.
There's a long history of anti-dualism in Kabbalist traditions, Christian Mysticism and Gnosticism.
For example, the Gospel of Thomas sayings #3, #77 and #113.

I like his interface theory and the idea that our perception is an evolutionary fitness for purpose, but his conscious agents is straight out pseudo-religious/panpsychism.
> Then he declared that there is another distinct problem — why the brain’s behavior is accompanied by experience at all — which he christened the “hard” problem of consciousness.
The hard problem isn't about "why", it's about "what it's like".
Try to explain what it's like to hear a major and a chord to a deaf person, or what it's like to see magenta to someone who's blind.
None of the things you say, sign or write will make them experience these sensations.
Ultimately no one but you can know what it's like to be you.
This doesn't mean that subjective experience can't be modeled. but the caveats that apply to models in general are relevant here too: none are correct, some are useful.
Dualism doesn't necessarily means that subjectivity is ineffable. Mind and matter could work like mathematical duals: platonic solids (cube vs octahedron, dodecahedron vs icosahedron, tetrahedron vs itself), Voronoi diagrams and Delaunay triangulations, etc... These are intimately linked, and you can generate one from the other and inversely, yet they have their own distinct properties.
I know this isn't what you wanted, but the dualism struck me:
A major chord is like a blend of two base colors that give rise to a pleasant composite color. Mix the wrong bases and the result is sensibly wrong.
Magenta is like when you play a D and an F# together. When you see it at sunset it's like a major D chord surrounded by the sound of babies laughing. When you see it on the battlefield it's like a minor D chord wrestling against the noise of wind and rain.
These are very good analogies (and possibly experiences for those who are natural synesthetes), but even then, that won't make the who doesn't have the corresponding perceptual modality person experience that exact sensation.
why does a major chord sounds pleasant? and why does a minor chord sounds "sad"? Why does the locrian mode sound so unsettling? is it due to our anatomy or purely cultural?
That being said the nature/culture duality is often not the right way to frame these issues. It's both, intertwined.
This reduces to the intractable mystery of existence. A more interesting question would be, as usual "how".
There are serious attempts at this, coming from both neuroscience and physics (e.g. for the latter https://pubs.aip.org/aip/adv/article/15/11/115319/3372193/Un... )
This has caused my own position, over time, to be a deep agnosticism about what's actually going on.
There are of course other reasons too, with things like religious beliefs and human ego meaning that people come to the discussion with a major bias and fixed views rather than even being open to any rational discussion.
Finally, everyone is conscious and has an opinion, but only a tiny fraction are actually knowledgeable about the brain and have spent any large amount of time thinking about things like evolution and brain development .. they have an opinion, but are just not qualified to discuss it!
If you break down all the different things that people are referring to when they talk about "consciousness", and define them individually with as little wiggle room as the english language and underlying taxonomy of concepts allows, then I really don't think there is much mystery about consciousness at all, but of course those with an agenda who want there to be a mystery will still argue about every part of it including the definitions that remove all the wiggle room.
The nature of consciousness has long been a contentious subject, and one of interest, but it seems that the rise of AI has intensified the discussion with the new question being whether AI is or could be conscious. I do think this can be answered in a principled way (=yes), but in the end you can only PROVE that something, or someone else, is conscious if you accept a functional/testable definition of it in the first place.
Best example is Darwin's "Origin of Species"; here, Darwin didn't rigorously define "species": 'No one definition has as yet satisfied all naturalists; yet every naturalist knows vaguely what he means when he speaks of a species.'
Many in the social sciences fetishize definitions, operating under the false notion that formulating a precise definition is the primary goal of inquiry. In reality, a robust scientific theory is a structured set of hypotheses; when combined with auxiliary theories, it derives a specific set of testable consequences.
Even within this framework, one must remain vigilant against ad hoc explanations. An ad hoc explanation fails to provide genuine systemic insight because it is engineered solely to fit the target phenomenon; it eliminates the explanatory gap by simply re-stating or absorbing the explanandum without offering any independent predictive or falsifiable power.
You're right, but that rigorous definition is a significant part of the problem. We have a very difficult time rigorously defining and then debating certain attributes about consciousness or related concepts precisely because the definition and exploration of the definition is what is being debated.
This makes it a very fascinating topic.
For my own pet theory I think consciousness as we like to understand it is an emergent and evolutionary social construct for cooperation amongst humans, and different people may have different levels of conscious thoughts, similar to how mammals are conscious in a different way amongst other species. It's a spectrum. There are, in fact, philosophical zombies.
You're forgetting that attempting to have a "rational" discussion is itself a bias inherited from the many centuries of intellectual development that occurred between the middle ages and now - the parts that the article conveniently skips over entirely.
The "debate" here doesn't function to generate an answer, but to narrow down the scope of the question into the very constrained domain. When ppl debate "consciousness" they are re-affirming their opinion that humans are inherently rational agents (hence "scire" -> "to know"), rather than agents that can live, feel, think and will, which would require a different term, like "soul".
Are you actually qualified to discuss this by your criteria?
Funny enough most people who don't want to meditate or practice mindfulness, also get dissuaded from the dissonance this brings up, and like the old me, just move on to more comfortable conversation.
It's 'one' of the few places? That behaviorism seems to be define almost all modern discourse from politics to health care including about 95% of Hacker News posts as far as I can tell...
For the sake of argument, let's take a particularly long-lived species and say oak trees have some form of awareness. An oak tree's perception of time would be completely out of line with ours, from its perspective it'd be this writhing, visibly expanding thing that can't even register individual humans since we're there for such a short period of its existence. If it were aware on some level, we wouldn't be able to tell either way because we can only really conceive of human-like minds; even though an 'oak tree mind' would look nothing like ours because it would be driven by entirely different evolutionary conditions. I don't think it's possible for us to be entirely objective when it comes to naturalistic theories of consciousness, we cannot avoid being biased by our 'version' of what we're studying.

In his theory, consciousness is a "controlled hallucination" about what is outside of us. Our senses serve to reinforce or correct the predictions our brains are making. (we have a serious latency issue)
You'll find he's saying a lot of the same things you just wrote.
> There is no way to allow each limb to do its own thing, or the brain not to decide what comes next in a unified way.
This is of course not true. I’ve watched people trip over their own feet because the simultaneously tried to go both left and right. I’ve done it myself.
And this says nothing about consciousness. Most actions are not conscious.
I can pat my head and rub my belly at the same time.
What? Why not?
It's physically possible in terms of limb motion. It's very difficult for most people to actually do, sure; but impossible?
or the brain not to decide what comes next in a unified way
There's the idea that a lot of the brain's "conscious decisions" are actually post-hoc rationalisations of unconscious decisions. If so, there's no reason those decisions have to be unified. Maybe the consciousness of the decision and its outcomes must be unified; maybe that's somehow connected to what consciousness really is. Or maybe not!
I don't think there's enough information to say.
There probably isn't any simple causative explanation (as in the example you provide). The brain is the most complex structure we know of and "self" arises from that deep complexity; this is an answer that I'm content with, as anything more in-depth / closer to the "metal" would quickly exceed my ability to understand it.
What if it reveals itself to us?
What about the NPC meme? LLMs behave like NPCs, and some people seem no more conscious than an NPC (I didn't invent that meme).
No sir, we are a little more high brow around here. Around these parts we talk about p-zombies and solipsism!
I'll bite though, do NPCs behave as if they believe they are conscious? If so, how do you know you aren't one of them?
I have never had an conversation with someone who seems like an NPC.
Good on point response in my opinion. A lot of people want to close doors because those doors being open makes them uncomfortable. This is a mistake. If you want to be rigorous about what is then you need to be equally rigorous about what is not.
Experience is subjective. That's why we need science in the first place.
His Baroque Cycle series also touches on this in several places. One funny side plot involves a freed African slave (Dappa) who speaks dozens of different languages and is highly intelligent and an aristocratic person who maintains that of course this former slave (who is obviously a lot smarter than this aristocrat) is just a trained monkey that naturally is not conscious even though he is quite clever with language. The same books also have a lot of side plots involving Leibniz and various attempts to build thinking/computing machines.
The Dappa plot is probably the closest to a lot of debates there will be around AGI with people likely to insist for all sorts of reasons rooted in philosophy, religion, etc. that even though the AGI walks, talks, etc. like a duck, it can't be a duck. At some point, we'll have AGI that pass any test we can think of and we'll still have people arguing that these cannot be conscious.
Is there a distinction in your mind between consciousness and intelligence? Is it possible, for example, for a machine to solve complex problems but not be conscious? Or vice versa, can an animal or a person be very unintelligent yet still conscious?
In my humble opinion, which I have no way to prove or disprove, consciousness ("as a soul with extra steps") does not exist, and we are all philosophical zombies. Consciousness "as an amalgamation of complex biological signals and neural interactions that has evolved through millions of years as a successful survival strategy" does exist, and that is all that is needed.
https://en.wikipedia.org/wiki/Philosophical_zombie
>For example, if a philosophical zombie were poked with a sharp object, it would not feel any pain, but it would react exactly the way any conscious human would.
in the Wikipedia article because I don't get on well with the sharp poking. On the basis of Occam's razor I assume all other humans and higher animals are similar. It would be odd if evolution had made me different from all the others.
I'm of the school of thought that we are all biological computers with emergent properties like intelligence, consciousness, etc. that we might eventually succeed in replicating. Maybe at a more modest level at first. From a practical point of view, I'm more interested in intelligent agents than conscious ones. I mainly need them to do useful things for me. Too much consciousness is a double edged sword. Because then I would have to consider how my agent feels about all this. But can you really have one without the other? I don't have a good answer to this.
People have a tendency to anthropomorphize everything around them. Definitely their pets, plants, and in some cases even inanimate objects. Which doesn't help the debate because it's already happening with LLM tools. Even though they are probably still on the definitely not conscious side of the fence even when they demonstrate mildly intelligent reasoning occasionally.
At some point, people will have a hard time telling the difference with AGI. Is it all smoke and mirrors at that point or are they dealing with an intelligent/conscious thing? That's no doubt going to entertain philosophers for centuries to come. But from a practical point of view, does it really matter at that point? If we can't reliably tell the difference, is there still a difference?
You've already drawn your line in the sand (i.e. they are conscious). In that case, you can't also claim that we should continue producing them by the millions at the flick of a switch.
The AI-is-conscious crowd will have to choose - either they are conscious, in which case they should not be birthed, or they are not conscious in which case we can use them as tools. You can't have both and still be logically consistent.
Sure, but we don't create as many as we can, then kill them at the end of the day when the work is done.
If you want to call AIs conscious, you can't also campaign for willy-nilly creation, even if they do get a status of a working tool (dogs, etc).
If you think they are conscious, which implies laws protecting them, then the "owner" of them gets an obligation (you can't do whatever you want to a dog, for example).
This is a great example for a discussion about The Hard Problem. Here is the description from the book of the inner experience of this scanned brain as it gets booted up:
> What came next could not, of course, be described without using words. But that was deceptive in a way since he no longer had words. Nor did he have memories, or coherent thoughts, or any other way to describe or think about the qualia he was experiencing. And those qualia were of miserably low quality. To the extent he was seeing, he was seeing incoherent patterns of fluctuating light. For people of a certain age, the closest descriptor for this was “static”: the sheets, waves, and bands of noise that had covered the screens of malfunctioning television sets. Static, in a sense, wasn’t real. It was simply what you got out of a system when it was unable to lock on to any strong signal—“Strong” meaning actually conveying useful, or at least understandable, information. Modern computer screens were smart enough to just shut down, or put up an error message, when the signal was lost. Old analog sets had no choice but to display something. The electron beam was forever scanning, a mindless beacon, and if you fed it nothing else it would produce a visual map of whatever was contingently banging around in its circuitry: some garbled mix of electrical noise from Mom’s vacuum cleaner, Dad’s shaver, solar flares, stray transmissions caroming off the ionosphere, and whatever happened when little feedback loops on the circuit board got out of hand. Likewise, to the extent he was hearing anything, it was just an inchoate hiss.
The Hard Problem asks: who is experiencing this qualia and why is there an experiencer at all? Stephenson writes how this simulated brain is experiencing static as it condenses into meaningful patterns, but he implicitly starts with someone experiencing this static qualia. If this is the very beginning of the simulated brain booting up, where did this experiencer come from?
> At some point, we'll have AGI that pass any test we can think of and we'll still have people arguing that these cannot be conscious.
Because you're conflating intelligence with consciousness. There is no test for consciousness. In fact, you can't even prove that other human beings are conscious, you only know that you yourself are because it's self evident to you (cogito ergo sum, I think therefore I am). The whole point of the hard problem is that you can imagine something exactly like a human being that passes every test of being a human being (e.g. an AI) but still not be sure that it has any inner experience.
There's the Glasgow Coma Scale "the most widely used tool for measuring comas and decreases in consciousness"
https://my.clevelandclinic.org/health/diagnostics/24848-glas...
I know it's probably not what you're thinking of but does illustrate these things are not totally beyond testing and experimentation.
> We have souls. We have an inner self. We can treat ourselves as transcendental subjects in the Kantian sense. We have emotions and spiritual life; we experience qualia. These entities are not obtained by addition to a physical state, but by subtraction from a complete physical account. Mental processes are physical processes described in a way that captures only their salient characteristics.
followed by this:
> The reason why this picture is more credible than any dualism is not that “science explains everything” — it doesn’t — or because “physics explains everything” — it does so even less. It is because of the hundreds of years of astonishing and unexpected success of the sciences that have convincingly shown that apparent metaphysical gaps are never such.
followed by this:
> Earth is not metaphysically different from the heavens, living beings are not metaphysically different from inanimate matter, humans are not metaphysically different from other animals. The soul is not metaphysically different from the body. We are all parts of nature, like anything else in this sweet world.
So it isn’t describable by physics but it is only physics? And there are no closures or gaps? Ok sure in one sense we can say everything is connected, but this article seems to me to demonstrate effectively that without these divisions, pursuing understanding of it is essentially intractable.
He seems to be describing the dissolution of some construct in his worldview that I am having a difficult time relating to. Anyone have a different take?
It just means we can't know without paying the price, walking the path of the process, step by step. No jumping ahead. We can't even predict a 3 body system far ahead. We can't tell the properties of a code without executing it. We can't compress most processes, their execution is the shortest description. Chalmers wants 3p to eat for free at the table of 1p.
"A landscape of consciousness: Toward a taxonomy of explanations and implications"
https://www.sciencedirect.com/science/article/pii/S007961072...
It seems to me that Chalmers already precludes the possibility of physical/materialist explanations with his claim, quoted in the first section:
> There is a logically possible world physically identical to ours, in which the positive facts about consciousness in our world do not hold.
This certainly doesn't feel obvious or intuitive to me. I would expect that someone with the same neuronal make-up will have the same experience.
In my regard the weak link is our understanding of materialism. It is to simple minded. (though panpsychism sounds really crank)
Neither does pure materialism rest on falsifiable beliefs, in that I could claim nothing exists outside my conscious experience.
If ten years from now your phone tells you it is conscious, would you believe it? What criteria would you use to decide?
If we go falsifiability, again, I can equally say how do I know your concious, or even that how do I know youre alive and breathing beyond the moments that I myself am observing you?
This is an metaphysical discussion, so falsifiability is kind of irrelevant. All metaphysical positions are ultimately unfalsifiable - including materialism and physicalism just as much as dualism or monism or theism.
This is not true, there are many metaphysical positions that are falsifiable.
For example, "anything shaped like an apple is an apple" is a metaphysical position. It defines what it means to be apple-ish. You could hold that metaphysical position and also "apples are always made of plant material" as another position you hold at the same time.
Then you could falsify the metaphysical position by presenting a stone carved into the shape of an apple. You could choose to deny reality and change your physical definition (what the definition of the word "apple" is), but if you think logically the evidence constructively falsifies the original metaphysical position.
I think what you might have been trying to say is that people tend to adopt metaphysical positions which are non-falsifiable. Yes, they do, but that doesn't mean no metaphysical arguments can be resolved through logic and experiment.
So yes, some metaphysical statements are falsifiable, and some have in fact been falsified over time. And, very importantly, many of the biggest metaphysical questions have no known falsifiable answers (at least none that are not already known to be false, of course).
If souls can influence the world, as is the common belief for souls, then in principle that influence or its absence can be detected.

EDIT: Downvote all you want, materialists, but reincarnation is the spanner in the works nobody wants to confront ..
If you believe in reincarnation, for some reason brand new souls are spawning into existence. Why? How does reincarnation work for them?
Because souls split. Like rain and the ocean.
> But the argument is weak. A philosophical zombie would claim to know what subjective experience is; otherwise, it would be empirically distinguishable from a human. Chalmers’s point is that the existence of the hypothetical, irreducible consciousness of which he speaks is something we can be convinced of only by introspection. During introspection, physical processes in my brain convince me of my consciousness. The same would theoretically happen in the zombie brain, convincing it of having consciousness as well. If this is true, can I believe my own conclusion of having this mysterious non-physical experience, knowing that if I were a zombie, I would be convinced of the same without actually having it? The argument is self-defeating.
My reaction here: it seems to me that the p-zombie by construction doesn't have a "me" to be convinced, so "physical processes in my brain convince me of my consciousness. The same would theoretically happen in the zombie brain, convincing it of having consciousness as well." doesn't make sense.
Therefore the demonstration that the argument is self-defeating fell appart, and I stopped finding the article insightful.
Can someone help me see what I'm missing?

Many of these already gave up on dualism: they already rejected the idea that mind and body are separate (e.g. panpsychism, the idea that consciousness is a feature of reality, that all matter possesses "experience" of some kind).
In my eyes, consciousness is simply a natural phenomenon that can be explained but we just lack the understanding at this moment. Time and time again we have made this mistake of assuming there is something supernatural about the things we cannot comprehend and only a few centuries later it is completely understood scientifically. I think consciousness will be a similar case but will take more time.
The real question is whether there is a two way link between consciousness and the physical world. Obviously the physical world is observed by consciousness, so that direction checks out. What about the other direction? Is the physical world at all influenced by consciousness? The mindfulness folks seem to argue: no. They argue that consciousness is like a person watching a movie, where the movie is experience. The person is so immersed that it thinks, it controls the movie, but in reality it's a fully passive observer. But this can't be true! Otherwise, the discussion of consciousness could never have come up in human history. A population of "philosophical zombies" could never initiate this discussion. So somehow consciousness must cause physical neurons to activate. The movie knows about the person watching!
But I agree with your overall premise. It can be all understood scientifically. There is nothing supernatural about things we cannot comprehend.
From Plato vs Aristotle (300 to 400 BC) (idea of forms vs nicomachean), In India Adi Shankara (around 700 CE) vs Madhavacharya (1200 CE) (dualism vs non-dualism) - there is a common thread to all of these arguments.
But eventually, for me it comes down to a statement J Krishnamurti made (& it makes the most sense to me): "The self is a problem that thought cannot solve"
It could be true that there's only physical body, but still have the qualia explanatory gap.
My go-to analogy is the concept of heat and warmth, which was the subject of philosophical speculation and inquiry for centuries. But ultimately it was not useful or predictive until it was redefined very narrowly by scientists as a specific measurable attribute of a collection of molecules. Arguably this redefinition itself was an important component of the establishment of “science” as a discipline distinct from philosophy.
This let scientists work with heat rigorously, even though non-scientists still have a largely colloquial vocabulary about it, e.g. “this coat is warmer than my last one.” On matters like consciousness, we’re all still smashed together into colloquial land, arguing about definitions when we think we are arguing about concepts.
I do think the current advancements in AI may help us develop the new vocabulary we need to quantitatively reason about intelligence and language, and in doing so, help better define / constrain what the we mean by consciousness. We think of LLMs now as a tool we can use to do work, but another view is that they are a sensor that directly correlates physical inputs to intelligent outputs. Sort of like how burning can be used to measure the energy contained in various materials, in addition to keeping us warm.
I don't know what qualia is, but it IS something. Some people don't seem to get any arguments and debates about it, at all. Others do. I doubt the people that don't get it are zombies but it's weird that someone can't even comprehend what the issue is about. When I say "red" or "pain", they talk about neurons and whatnot. Of course that's true, but don't they feel the redness and the pain subjectively in a way that makes them question how that feeling relates to the atoms, neurons and other levels of abstraction could be used to describe the physical reality?
And I think, having read a bunch of philosophy years ago that solved nothing, dualism or not is not the right question right now, in our level of understanding. It's not even the right answer because what's "physical" is not well defined either. If we can explain qualia, why would that explanation not count as a "physical" one? If there's some logic to it, it's as physical as anything else.
Lots of ill-defined questions and assumptions. I think we should accept qualia is not understood and won't be for some time. We should realize we can suffer and so can beings similar to us. Where do we draw the line - we'll have to base that on what we know about biology. To me it's obvious many animals are capable of suffering. I think that's a good place to start with our ethics. Suffering is shit, let's reduce it as much as possible.
Or a gap between my mind and the minds of the other commuters on this bus.
There are 15 or so biological machines here, but only one of them is being experienced in bright sound and colour.
We understand everything a CNN or Transformer does, but we have no idea how to relate that to qualia. This may also be why we need to run endless tests and don't have a theory that let's us predict how well the network processes anything.
The problem with that common definition is that it doesn't make much sense. Every philosopher that ever talked or wrote about the hard problem and qualia did so with plain old physics, by moving their mouth or using their hands to move a pen or keyboard. You can, in theory, trace how those physical interactions happen, all the way down to the neurons. Meaning the reason why they talked about qualia boils down to plain old physics.
There is no scenario where the easy problems are solved and the hard problem remain. For there to be a hard problem, the easy problems must be unsolvable, but then you don't need a hard problem, since the easy problems are already hard.
It was proposed by Chalmers as a young undergrad at the Science of Consciousness conference. I have been attending for awhile and really enjoy it. There are so many opinions and thoughts on this post, if you are really into thinking about consciousness, this year the conference will be in San Diego. It's a long day of lectures, followed by evenings of great conversations. https://cs2026.org/
>to explain how and why organisms have qualia or subjective experience. (from Wikipedia)
(or "why the brain’s behavior is accompanied by experience at all" in the article)
He then supposes this "assumes upfront that there exists a metaphysical gap between mind and body". But there probably isn't so he jumps to:
>So, there is no “hard problem of consciousness.”
But that doesn't explain how/why there are qualia and the like.
I personally think how/why qualia it a real hard question but scientifically tractable.
A little guessing. You can assume we evolved - much evidence - and so consciousness has survival / reproductive functionality. The brain has billions of sensory, memory and other neurons and they have to compress that data down to something a creature can act on - should it feed of run away etc. So conscious awareness is probably something like a situation summary you can act on.
One interesting thing is there is a lot of unconscious awareness and actions going on - when you walk across a room the nervous system has to process all sorts of stuff about your body position and coordinate dozens of muscles but you are normally not consciously aware of it, so presumably the conscious bit of you brain is some small portion linked to the thinking talking and remembering bits.
I think much of the subtlety of conscious experience is because there is a lot of unconscious things underlying it. You see say a red apple and it's linked to memories of apples, instincts for food, evolved associations with red, your mood and the like. It all gets reduced in something like a lossy compression to what you are aware of.
I think children's main "cost function" is the ability to predict the future. This might start out, for example, as being - how will this vertical line move as I move my head. Later, where is the ball going. And they are essentially building a "world model" in their brains, starting with the very simple like this and recursively building more complex predictors. When they predict correctly, happy feedback reinforces the connections that are firing, when they are wrong, they weaken. Just a really simple feedback algorithm that is super robust.
So the brain is building this world model, and it's essentially gradually compressing a description of the environment into a structure made of neurons. And this is the ultimate survival tactic: model the environment explicitly in your head, then adapt your behaviour to fit it. The better you are adapating to future states (dodging that tree as you run) the better survival chance you have.
At some point (complete speculation) we then begin to do something quite strange: we develop a world model _of ourselves_. We get to a level of sophistication where we begin to predict the future states of our own brains. This might emerge naturally as a way to compress existing learnt behaviour. For example, we re-learn to follow lines in a smarter way, particularly as other parts of the brain learn useful things that we can re-use in our line following. This treats our existing model as a cost function, and we learn a model of the model. But it eventually starts to model the higher-level models the brain has, higher up the abstraction stack.
And somehow, the modelling of our brain function creates a chaotic feedback loop that leads to the sensation of consciousness. It's super handwavey, I know, but somehow this recursion feeds awareness. It's like the abilty to see yourself thinking. Consider meditating and the way words appear in consciousness... you get to a point where you can observe what you're going to say before you say them, and I conjecture that is the modelling of the model that's going on.
And this is useful for survival, as you can optimise the way you think, compressing your circuits further, but also has this weird side-effect of creating awareness.
It also explains why consciousness takes time to develop - because you need to develop a model of yourself, but before that you need a model of the world.
At first the process is subconscious, then chaos enters as our conscious awareness develops, morphing the control loop into second or third order states of "correcting corrections" as we perform inner tasks such as ruminating, or external tasks such as group discussion and logical planning.
The perfect prediction machine would be a simulation running an entire up-to-date universe model, but between our limited physical resources and available energy in reality, our evolved aim is efficiency, by creating a state of awareness and reactive patterns with minimal information (lowest entropy). We do this by making assumptions, testing the world, then processing the response and updating our control loop. The tradeoff is lack of precision, as a model without complete information has guaranteed errors.
Children who form a more realistic core worldview through guidance, opportunities and experience are best set up to create solid foundations which are more adaptable to future unexpected situations. Whether this is learning emotional response in social settings or math, the ability to integrate future conscious experience depends on early neuronal structures formed by subconscious expectations of the world. If measurement error is too great from expectations and our current loop/wavelength, our options are to discard this information or learn from it by reflecting on sources of inevitable prediction error through reasoning.

> I fail to make sense of the claim that there is such an “explanatory gap.”
This is essentially saying "I don't understand therefore you are wrong".
> We do not need to explain why it looks red for the same reason that we do not have to explain why the animal that we call “cat” looks like a cat. Why should we have to explain why “red” looks red?
We did in fact need this to get AI to recognise cats.
If we wish to actually know if some AI is or is not conscious, and not simply re-hashing conversations ancient Greeks will probably have had as animism faded from their culture and they stopped believing in dryads and anima loci, then it needs to be testable *by something outside the intelligence being tested for conscious*.
> Scientific knowledge is ultimately first-personal. The world is real, but any account of it can exist only from within it. Any knowledge is perspectival. Subjectivity is not mysterious
Mysteriousness isn't the problem with subjectivity, lack of repeatability is. This is why we make instruments to measure things: my "about the size of a cat" is subjective and likely different from yours, while my "31.4 cm" is only going to differ from yours if one of us is surprisingly bad at using a ruler; my "pleasantly warm" may or may not be yours, but my "21.3 C" will only differ from yours if one of our thermometers has broken.
The "hard problem of consciousness" is that we not only don't have a device to measure consciousness, but even worse than that we don't even know what its equivalent of a ruler or thermometer would do.
(At least for this meaning of consciousness; there's at least 40, we can at least test for the presence or absence of the meaning that e.g. anesthesiologists care about, but that's not the hard problem).
I believe that this is simply because of the way we train ML, with labelled data. It is quite conceivable that we could get an ML model to recognise cats just by some form of multidimensional clustering of training data.
This would also impact clustering.
That said, I think even for humans there's a similar issue: we spent millennia clustering things into groups and labelling those groups, which is why the Catholic church had rules about no meat on Good Friday but fish was fine and beavers counted as fish (and there is now a podcast titled around the idea there is no such thing as a fish*). For cats, I don't see it myself but the fossa is described as "cat-like".
* https://en.wikipedia.org/wiki/No_Such_Thing_as_a_Fish#Title
Of course what a cat _is_ to me is not what a cat _is_ to you, because we necessarily have different memories of interactions with cat-like beings. If you show some babies a cat for the first time, they'll necessarily see it from different viewing perspectives. Even if you put VR glasses on them and show the exact same video, they'll have different contexts: "I first saw a cat when I was sitting next to my friend", "I first saw a cat when I was thinking of ice cream", etc.
But they all saw the same cat, they'll see many other cats, who are all similar. So everyone will understand that "things like these are cats", but everyone will have their own understanding of a "cat" because their memory is different.
It's probably sensible to use more strongly defined terms like humanity, self-awareness, cognitive capability, empathy and so on. And to treat them somewhat separately rather than trying to bundle it all together.
But people want there to be something special about us which can be defined as something separate from us, in a neutral, universalist sounding way which also happens to be relatively exclusive - I think because there's this desire to make the concept of a soul have an equivalent in scientific realism for the purposes of discussing philosophy in a secular way.
It’s a subjective experience argument. As a conscious person, if someone tells me they don’t believe in consciousness, then I’m inclined to believe they have a reason for saying that. They must not be experiencing consciousness the same way I am.
Interestingly, a non-trivial number of people have no internal monologue (https://www.iflscience.com/people-with-no-internal-monologue...). It would be reasonable to assume the experiential side of consciousness is on a spectrum, with extreme edge cases on both ends. It’s not unreasonable to assume that some people are barely experiencing it, and some not at all. It would certainly explain to me (someone who experiences it quite intensely) why some would claim it doesn’t exist. Because for them, it might not.
It would be fine for an unconsciouss intelligence to maintain that hypothesis lacking any evidence to the contrary, but for us it seems we are just all gaslighting ourselves to ignore the one counter example we all have.
Can cow/dog/spider suffer? - very important question, even if not answerable.
When you look at a cell, you can clearly see how the dynamics are existential and already do the work of classifying inputs as "good" or "bad" (eg: paramecium encounters acid, this triggers an electro chemical cascade in the membrane cortex which results in the organism quickly changing direction away from the bad gradient). There's no mind obviously in the human sense, but the fact remains that this system has developed into something that can discriminate between good and bad for itself, because without this integration, it wouldn't exist.
The cell is as close to a machine as possible. But it's not a machine because people make machines to have specific purposes. Each part is already labeled and designed. You can shut down a machine that's running, and start it back up with very predictable behavior (since you designed it).
The cell is a process that uses physical matter to keep its own possible futures available. Machines also support processes and goals, but these are externally imposed. The cell's ultimate goal is to continue being the reason for its own existence. Maybe this is where all goals come from.
So I guess experience is what happens when you have enough layers above this machinery that you you are no longer connected directly to the world, "you" can only meet the world through internally generated/classified electrochemical states from the body. These states have valence because the system is already organized around maintaining these states within metabolic limits. Think...hunger. You don't feel hungry. You ARE hungry. Hunger is a part of how "you" are constituted.
I think that the idea of a soul or spirit could be both interesting and also self evident though, so it's odd to read these being thrown out in the same bath water.
I.e if we imagine our simplified brains as points of matter with signals being sent between; then the kind of experience we have as human beings is more about the relationships between the matter. I don't see that as a harmful duality as if it were the case, it would shed light on what we understand and how. We're still physical but exist in "spirit of matter", different but bound. No magic required.
I'd see this as fairly separate from the question of why we witness ourselves, which seems more prone to mental trickery.
Rovelli also has some fun popsci book on how Time might be constructed. Mostly a fun read but the theories, when he gets to them, are an interesting take. Highly recommend.
[1] However if Carlo Rovelli were a philosophical zombie, are these exactly the responses he would give - as it wouldn't "see" the moment of awareness and be confused by implied significance? I think so.
This has to be one of the most dumbfounding pseudo-philosophical sentences I've ever read. Metaphysics by definition is unfalsifiable and unscientific; it exists on a parallel plane from empiricism and is derived only through intuition, reason, and for the religious revelation. If this guy's claim for material consciousness simply rests on an intuitive argument from induction, it suffices as a counter argument to say "If I am mistaken, I am".
Here is a parallel argument for you. The history of science has been one discovery after another which leaves us with new, increasingly complex unanswered questions about phenomena. It is reasonable to think that if/when we reduce consciousness through science we will find that there are more increasingly complex unanswered metaphysical gaps.
I do believe what the author claîms, but it’s not something that’s proven so far, so it can’t be imposed as fact.
The main consequence to the “soul” being physical is that free will is an illusion. And many people can’t stand this idea. People want to believe they are more than a deterministic physical process. They want to believe the future is not already written.
They’ll look for free will in what still stands : god or quantum uncertainty.
God can’t be disproved, and quantum uncertainty leaves room for a kind of mystery, that’s appealing.
But LLMs definitely do a convincing job at “faking consciousness”.
I believe that we can at least posit some kind of mechanism through which emergence can happen. In my opinion we should look at language and how language evolved. However, i also believe we should expand our study of natural language to things like network protocols, and observe the "protocol hourglass" structure that has emerged from the internet protocol stack.
In my mind, the concepts of control and autonomy are what need to be revisited. We conflate the two: we are autonomous IF we are able to exert control on the environment. However, I think the reality might be that autonomous systems are more similar to an API in the sense that we can interact along the boundary but through the API we cannot exert control over the internal structure of the system (through knowledge or physical control).
Ironically, I think this article serves as quite a strong defense of the hard problem, because it shows how hard it is to articulate or construct an argument against it at all.
> That is, consciousness is hard to figure out for precisely the same reason thunderstorms are: not because we have evidence that it is not a natural phenomenon, but because it is a very complicated natural phenomenon.
That's flat out bullshit, and it completely misses the point. I know thunderstorms are incredibly complicated, but there is nothing about them that seems "mystical" to me, if you will, because of that complexity. If you have a basic understanding of the underlying principles, it's not hard to see how a thunderstorm would arise out of that complexity.
Consciousness feels completely different to me. That fact that the physical world can give rise to a core sense of self doesn't make any sense to me, and hand waving it away as "well, it's just more complicated" isn't actually an argument. My experience with ketamine therapy for mental issues only greater heightens this belief.
I don't believe the "soul" needs to be completely independent from the physical world (and indeed, my ketamine experience where a relatively simple chemical greatly affected my personal sense of self and experience is proof enough to me that it's not independent) to believe there is "something else", whether it's related to quantum phenomena or some other "plane" or field we just haven't discovered yet, to believe that consciousness arises out of "complexity" of other phenomena we already understand.
And this bit:
> I don't believe the "soul" needs to be completely independent from the physical world [...] to believe there is "something else", whether it's related to quantum phenomena or some other "plane" or field we just haven't discovered yet, to believe that consciousness arises out of "complexity" of other phenomena we already understand.

So, what, "complexity isn't a sufficient explanation," and _also_ "it's perfectly reasonable to believe it's the result of processes we don't understand?"
Every time this discussion comes up, people get _irrationally_ emotional about it. Which I think is, itself, very interesting data.
Those are not conflicting arguments.
The former means that we understand all the processeses, but they are complex, therefore we don't have enough brain/compute power to properly model it.
The latter means that we don't understand some of those processes, so we need additional theories that explain them.
One can dismiss the first while finding the second plausible.
The reason TFA (and, frankly, your comment as well) pissed me off is that they drip with condescension to the core while completely sidestepping the problem in the first place. We have plenty of other examples of places where complexity can give rise to emergent behavior, but those behaviors are still easy to understand in the problem space of the domain - e.g. I may be amazed that I can converse with an LLM and it feels like it completely "understands" the conversation, but I don't have any conceptual problems with the fact that it's still just next token prediction under the covers.
But as hackinthebochs put it very well, in my opinion: "The hard problem identifies the in principle difficulty in explaining phenomenal consciousness, something not definable in terms of structure and function, given only the explanatory resources of structure and function."
So my negative reaction is based in the belief that what the TFA is doing is saying "there is no hard problem", and the response is "but why, because 'phenomenal consciousness' can't be described in terms of structure and function like every other instance that we understand that arises from complexity", and then TFA just gives a host of complexity examples that are completely unconvincing (and, again, feel like they completely miss the problem is the first place) and just basically ends with a dangling, unwarranted "q.e.d."
Like so much other material produced by people who (I suspect deliberately) confuse religion with the subjective phenomenon of existence
My objection would then be that actually, that's not true. The real statement would be "In everyday life (including science), we accept explanation gaps already in many places"
But this does not mean that we have to accept this particular instance of an explanation gap.
That there's nothing magical or supernatural in our minds and our consciousness is a given, otherwise, this becomes a very silly debate where everyone will have a strong position that can be neither proven nor disproven.
Maybe we are able to constrain what consciousness (or a mind, or a soul) is by figuring out everything it isn't. Does it have a mass? Can we measure its entropy?
We can, to a certain degree, identify images from the visual cortex. What else about the internal state of a brain can we extract? We did that to a fly's brain the other day - a very confused simulated fly that must have been wondering why its world had so low a resolution.
This is absolutely, completely, demonstrably false. Soul-body dualism was largely a 17th-century innovation, although Plato somewhat anticipated it. Most medieval Catholic thought rejected it (and continues to do so), being quite clear that the soul/mind and the body are one entity. How can people in good conscience write about things they're so ignorant of?
Gell-Mann suggests I don't read the rest of the article. A brief scan reveals a rehash of the common assertions with no serious attempt to reply to counterarguments.
from the book of
>prophet Ezekiel, exiled in Babylon, during the 22 years from 593 to 571 BC
.....
"...he nevertheless remained convinced that soul is an incorporeal and immortal substance that can, in principle, exist independently of a body"

Not true: Science is precisely about finding truths that hold even if our conscious experience of them vanished the very next moment.
> Empiricism, the grounding of knowledge in experience
Another false equivalency: by "experience" here he means "observation", not consciousness. Observations are data points, consciousness is not.
The answer to whether a submarine can swim tells you more about the person the about the submarine. Meanwhile submarines propel themselves under the waves just fine[1] , and stalk their prey with silent impunity.
Perhaps we should call these discussions "swimming submarine debates"?
[1] https://en.wikipedia.org/wiki/Alfa-class_submarine could hit 41 kts(47 mph; 76 km/h) ... which is pretty good for something that couldn't swim ;)
If we solved the Easy Problems of consciousness, i think we would find ourselves in a similar position where most people would simply accept that we had an explanation and move on but some people with a more philosophical bent would continue to search for underlying explanations.
It sounds like Rovelli's resolution is to acknowledge the centrality of subjective experiences to the formulation of scientific theories, and thus also to any theory of reality. Experiences are the starting point, with the rest being built up from them. Therefore, experiences should also be the first thing added into the bucket of things that one believes to be real. Meanwhile, any physical model of objective reality has a far more tenuous spot in that bucket. We may suspect it to be real through various deductions, but the further away we get from experiences, the more assumptions have to be made to get there. Anyway, I agree that there is no explanatory gap when reality is viewed in this manner. And this is a relatively palatable way to approach the question of reality (compared to, e.g., the mathematical universe hypothesis, which most find unacceptable). But as long as there is debate about what makes up reality and where experiences fit into that, the debate around the hard consciousness problem will continue, and I regard this problem to be of a different character (being far more philosophical) than, say, spiritualism or anti-Darwinism.
Dualism is probably mistaken. The only evidence we have for anything about physical reality comes from experiences. It does not seem logical to believe that there is a physical reality which is separate from conscious experience. Quantum theory hints at this, with how the observer becomes significant. But this does not make understanding how it all works much easier.
It's a bit like pain: to create better analgesics, we need to work at the lower levels closer to the biology, but a patient describing pain to a doctor works at a higher, descriptive level, as does the doctor. Where is the pain, what are its qualities (dull, sharp, shallow, deep, burning, etc.).
That's the emergence hypothesis. Largely insufficient [1] and the one of every person that doesn't really understand Gödel’s first incompleteness theorem tends to embrace.
[1] "We can treat ourselves as transcendental subjects" there is a confusion about expressions of a phenomenon (referent) and real phenomenons (object). It denies Qualia by reducing it to a verbal expression supported by an insufficient model of the universe (current state of Physics).
Kind of ironic given the bit of the article that focuses on P-Zombies and how they don't work because they have to be indistinguishable. Well, what if P-Zombies are real, and they are distinguishable, it's just not obvious because the P-Zombies grew up in a world where people talk about consciousness and lots of people around them have it.
That is, life referring to something inherently far more complex than inert assemblies remains perfectly valid in many monist perspectives.
[edit: took life rather than consciousness as an example, but the stated argument in the article seems to be equally applicable relevant for both concept, or any concept that suppose that emergent complexity is possible]
1. How do we determine consciousness?
2. How should we handle moral consideration of a non-biological system?
The first question is a red herring. It cannot be answered. We need to focus on the second question.
Let us hear about your experience of a wavefunction, Carlo.
The new hard problem: how do biological brains get so much done on such slow hardware? That's a real physics question. We're missing something.
Compared to what??
I felt like this paper nailed it years a go, and nobody has followed up properly.
The metric involved is basically impossible to compute fully, but easy to approximate. Any online approximation will model everything it can see have changes until it is satisfied.
Even the current Artificial Intelligence revolution is showing us that:
what was thought to be purely immaterial and intangible, that is, human abstract Reasoning and Thoughts, are actually tangible, physical, and even machine-reproducible.
Michael Pollan's "A World Appears" is a much more interesting and nuanced take. Very much recommended.
Once you ask that, you never need to explain anything. This is a magical process that can never be touched by observation or explanation.
Consciousness is something that is used to observe the outer world and science essentially describes patterns in our observations.
All scientific laws boil down to subjective perceptions, such as, when I drop an apple, I see that it falls down.
The point of the philosophical zombie is that they don't experience anything, nor do they convince themselves of anything. If they're "experiencing" or "convincing themselves" then they're not philosophical zombies by definition.
We all (presumably, although I might wonder about the author) know that consciousness is a thing, we don't have anything like a rigid definition of it. Perhaps we never will, but this kind of hot air is unlikely to ever get us closer to understanding it.
Tiresome article by someone just being contrary for the sake of having something to say.
The problem is: Implicitly presupposing the existence of philosophical zombies implies the duality gap.
It might as well be that philosophical zombies are mental construct that cannot physically exist, simply because building one will imbue it with 'consciousness' (as, it being the physical copy/simulation, it will be able to simulate also the 'consciousness'), in turn making it non-zombie.
Sure, but if you're going to posit a philosophical zombie, don't posit one that has a rich inner life, experiences qualia, and is ridden with self-doubt FFS.
one may collapse the dualism dichotomy to two distinct possibilities. in both cases this existence is a subset of some larger existence (true because self implies other). the first case involves a hard boundary between existences (externally one may only only observe, therefore our existence collapses to pure solipsism). in the second case, the boundary between existences is permeable (one may interact with our existence externally, therefore our existence collapses to solipsism with the addition of brain in a jar). in both these cases soul can mean something different, but it can still be seen to exist, unless one insists on dogmatic adherence to the rules of any one system in particular.
I think it also helps to sharpen this debate to remember that there is a moral dimension: many have adopted moral systems that widen their sphere of concern and care from the self to the community to the nation to the whole of mankind, usually under the intuitive precept that it is bad to make someone else experience suffering. Should we expand our moral conception of responsibility or care to non-human patients, and if so, which?
Such an irony. Humans have has since the bery beginning inflicted pain and suffering on other human beings. We are still doing it directly (e.g., wars) or indirectly (e.g., capitalism). The idea that perhaps in the not so distant future, machines may live better “lives” or be treated better than some humans is pathetic. But here again, there are some pets that live better than a 1000 humans nowadays
Something about that background, all the discussions about definitions and representation, the original article talking about dualisms.... It's certainly an experience.
He also echos the modern belief that observer and actor are two sides of the same quantum event.
I highly recommend any and all of his books.
Thus, it's worth exploring all these heavy hitter physics thinkers. You won't agree 100% with any of them but you might develop your own version of things by reading a lot of them.
I fully understand and appreciate that there are lots of things about quantum physics, and heck, the universe at large, that are unsolved and that we don't understand. I would actually expect that in order for us to understand consciousness better that we'll need to fill some of the gaps of the quantum world.
The reason why I didn't like the article is that I felt like it's misrepresenting the problem, as the comment I linked described. I'll try to explain with an analogy: In the late 1800s before the discovery of quantum physics, many physicists felt that the physics of the universe was solved and fully understood - the universe was basically just like a set of billiard balls set in motion a long time ago, and the future position of all those balls could be known if their states were known in the past. In that "pre-quantum" world, people still understood that emergent behavior could arise from complexity (even just classical complexity). This article just felt really hand-wavy to me by arguing "complexity is enough". For example, if a similar article were written in 1899, but then later we discovered quantum physics and eventually had a good understanding of how consciousness can arise from quantum interactions, I suppose the author could state "See, I was right - just more complexity!" But it would totally miss the point that "the missing piece" was actually the discovery of quantum physics in the first place, not just more classical complexity.
So I felt this article was strawmanning the problem to begin with. I don't have to believe in "magic" or "souls" or religion to believe that the tools we have to describe complex emergent phenomena are not sufficient to describe the subjective experience of consciousness, but Rovelli seems to be saying that "more complexity" is just the answer to everything.
It's a perfectly physical/mechanical argument that demonstrates that consciousness is much much more bizarre than we expect.

This log file is loaded into working memory.
I have aspergers and that's sort of how I experience my own consciousness, the result of different brain processes, summarised in a log.
People are mainly subconscious and not that many things propagate to consciousness and get recorded in the log, because it's a bottleneck.
Instead of recording the whole process of emotionally tagging things, people just "feel" something without reasoning. Only the emotional tag or intuition is recorded in the log but not the process to get to it.
Non-verbal communication is emitted and processed subconsciously, which is hard for me because of the autism and I arrived to the conclusion that fundamentally human consciousness is a spectrum and how much is recorded into it depends on neurodiversity.

The deeper layer is autopoiesis - the conceptual foundation authored by them that embodied/4E cognition builds on.
They defined cognition as a necessary property of self-referencing, self-maintaining boundaries in an information-theoretic/topological sense, not bound to any specific physical process.
This dissolves the dualism Rovelli targets in a way that pure materialist/eliminativist arguments don’t manage cleanly. Autopoiesis is fully physical (mathematically modelable, biologically grounded) but it locates consciousness in structural relationships and informational dynamics rather than a purely physical substrate.
Thompson’s Mind in Life (2007) is the contemporary version, and Varela’s later work integrates phenomenology directly.
I hold that it may be possible to use the toolkits of set/category/group/type theory to formalize these relationships.
Would be a vastly different conversation thread here if this work was more well known.
Why is it pernicious?
Rovelli is a reductionist, the only logically and physically defensible intellectual position, while dualism is inherently supernatural, invoking phantoms, phenomenology that is purely fictitious.
My understanding of positivism is, in a nutshell, that its goal is to reduce everything to physics, including social, inter-personal interactions. My read of the article is that Rovelli is focused on the intra-personal, so to that extent it isn't positivism, or is at least a limited, focused positivism. Extending Rovelli's thinking to the inter-personal would be, IMHO, a categorical error: While we may one day be able to fully describe the physics (and electrochemistry, etc.) of everything inside the person, physics is insufficient to describe what happens between people, at least to the extent that what is happening is a result of each person's actions, choices, etc.
I think this where bringing qualia in as a level of abstraction is useful: Everything about us is ultimately operating on our physical hardware, but not everything about us is "just physics", since our "us" (our OS, if you will), makes observations and chooses actions that are determined at least to some extent by the "us", and not just by the physical operations.
At this point, one could bring in Skinner and make everything operational conditioning, or Kahneman for a slightly different take where much of what we observe or consider consciously (the energy-hungry slow system) has been pre-filtered by physical processes that are not available to us (the energy-efficient fast system).
If those lines of thought are correct - and that remains an open question - then we could potentially arrive at a complete positivism wherein everything is determined primarily by our internal physics, though we wouldn't get predictability for the same reason that we cannot solve the three-body-problem analytically or predict the weather accurately for all time or predict with certainty the motions of the planets, etc.: There are too many inter-dependent variables, and modelling will always lag actual behaviour.
I think we are on safe ground saying that intra-body behaviour is all physics, and on safe ground describing some of the physics responsible for what we call thought, e.g., neuropsychological processes, but at some point we need to model things differently to continue to make sense, make progress. We get away from just-physics at higher levels of abstraction, with the challenge being to describe the transitions from one model level to another (corporeal electro-chemistry to reflective thought and action to inter-personal relations to sociology and economy).
Sort of like how we know that everything is quantum mechanics at the appropriate scale, but that QM isn't terribly useful for modelling weather, planetary motion, etc.
That's the reason it seems like a thorny topic.
To anyone discussing whether or not consciousness exist, tell me do you have proof that other people have consciousness? There's simply no credible answer to this question other than "well they have to be...cause we share the same material". But that is a experiment with a sample of 1. The weird thing is, if you are able to proof someone else's consciousness, that is just an extension of your own consciousness.
Next question, how do you prove that you are not sleeping right now? What proof do you have that you are not living inside an illusion? You have surely experienced the illusion of understanding i.e. you realized that you "understanding" or the feeling of "understanding" was wrong. What is to say that this is not happening now?
In reality, there is nothing to discover. There is just this and that is all there is.
Rovelli’s arguments were made a dozen times over by Dan Dennett, and made better.
His critique of qualia is unsatisfying because it never reaches Einstein’s problem: what the heck is the physicist’s meaning and mechanism of this thing we call “Now”? Rovelli owes us that answer. He spent a decade telling us absolute time is not fundamental, no universal present, no master clock. Take the clock out of the universe and the Now gets harder, not easier: if there is no clock out there, what builds the one the organism plainly runs on? Answer that, then explain consciousness and qualia to the neurophilosophers.
Now is probably a process built by asynchronous wetware to survive. Humberto Maturana said the mechanisms that construct it are atemporal. And yet here we all are, reaching for clocks and synchrony to explain the Now. The irony should not be lost on Rovelli.
The neuroscience is in print already: Bickle et al., Eur J Neurosci 2025 (doi:10.1111/ejn.70074. interview with R. Williams) where the wall clock is named as neuroscience’s most tacit and least examined assumption.
This is the standard blub programmer but in science. The blub physicists doesn't understand anything more complex or higher-level than his daily abstractions.
https://www.paulgraham.com/avg.html
Obligative sapience is only know to have evolved in humans. Obligative means we cannot survive without sapience. We must learn and use tools and whatever to live and continue evolution.
While facultative sapience seems to be a broadly used survival strategy across the animal kingdom - from crows to spiders to cuttlefish. Facultative sapients are able to survive without their learned behaviors, using them instead to augment their evolution.
Viewing these issues from the point of evolution and actually having a comparison, I feel, helps ground the discussion better.
Even more so from the very strange point of view of speculative biology. The creator of the 'Neotectons' gives a very strange viewpoint on the debate too, with good reasoning though not bulletproof by any means. As with any model, you can make it tapdance if you mess with the parameters enough. But I think that more efforts into speculative arenas would be helpful. Gedankenexperiments for sophonts and not just elevators and cosmology.

I think this has been obvious from the other side of the argument forever. Animals obviously have consciousness and emotional responses and they are made of the same living matter we are, but my pet bunnies can’t do natural language or math.
Matter and mind are not the same and mind is not produced from matter. That there are correlates between the body of a sentient being and the content of their experience is common sense but not proof that their body is causing the very ability to experience anything.
You would think that absolutely no progress being made on how dead matter somehow produces experience would make people question their assumptions. Instead you get people denying that they have a mind or just coping by thinking that if they map yet another correlation they will finally crack the code.
Can you explain any of this in a way that doesn't boil down to "it's magic and you just have to believe that it's happening because it is?"
But the "hard" problem of consciousness has nothing to do with the contents of the experience, but with explaining how experiencing of any kind is produced by aggregates that themselves do not have any such experiences. The simple answer is that mind (experience, consciousness, whatever you wanna call it) is not produced by matter and is a completely different realm of reality.
Maybe if science simply assumed that mind and matter are different things instead they would have made some progress. For once, the "hard" problem of consciousness would be revealed to not be problem at all. As for non-scientific proof that you have a mind, you can just observe that for yourself in every instant of your own personal experience. No magic involved. If people want to deny their own minds that is up to them.
Two things here:
1) How do you know I have a mind? How do I know you have a mind?
2) What is even your definition of "mind", and why (at least I suspect) is "the ongoing result of information processing facilitated by the complex interlinked network of neurons in the brain" not a satisfactory answer to you?
> Then he declared that there is another distinct problem — why the brain’s behavior is accompanied by experience at all — which he christened the “hard” problem of consciousness.
This is what the article is positioned against.
> We have souls. We have an inner self. We can treat ourselves as transcendental subjects in the Kantian sense.
Isn't this an equivalent declaration? I understand the desire to cling to such ideas (as the article itself propounds), but if you don't understand the underlying laws to a high enough degree I consider this equivalent to ancient Greeks sitting around saying "there is a double of our soul inside the mirror, WE HAVE SEEN IT". We know today there is absolutely nothing at all "inside" that mirror. How do we know all this qualia isn't just some sort of illusion, that we ACTUALLY experience something?
Unfortunately, this article puts forth an intriguing promise and then completely fails to deliver.
I know what it means to have an experience that is illusory. For example, a mirage, or a drug-induced hallucination.
What doesn’t make sense to me is how it’s possible for it to be an illusion that anything is being experienced at all. An illusion is a type of experience, isn’t it? If the experience is illusory, then who/what is being deceived?
(This is basically just Descartes “I think therefore I am”)
It might not make sense to you now, but that's because of what we know or what we think we know, today (hence my ancient Greeks analogue). Look at the Gazzaniga effect, people seamlessly make up an "experience" narrative out of absolutely nothing. Whatever experience was claimed there probably didn't exist prior to the point of questioning, and then was wholly manufactured. Thus, that particular experience was a fabrication.
> If the experience is illusory, then who/what is being deceived?
Why does there need to be a who/what being deceived for something to be an illusion? A mirror functions regardless of whether someone is there to pretend there is a soul in it.
We come from a race that took two thousand years (after it was first proposed) to accept the brain as the seat of the mind, over the heart — just because the heart physically reacts in times of emotion, while the brain remains inert.
Whatever the truth is, humanity probably won't know it until enough generations of the old guard indoctrinated in the old ideas have passed on.
Rhetorical nonsense. If I'm a student about to take geometry for the first time, I can certainly have a sense of what I'll understand when I "understand something [I] do not currently understand".
The explanatory gap, IIUC, is rather simple: we can't explain why neurons firing results in us feeling/experiencing the world. This doesn't seem controversial to me.
Feelings/experiences are specific patterns of specific neurons activating. Why is that hard?
Oh I hate this.
We ‘still’ can’t do any of those things yet. Science provides a framework for discovering and coming to understand and yes eventually accurately predict the motions of the underlying systems that give rise to these phenomenons.
And getting a mechanic to fix your bike is a matter of specialization, not some failure of science.
Does anyone actually enjoy hearing other people talk this way? Who is this for?
"Many felt confounded or degraded by the idea of sharing a family tree with donkeys. [...] Amid the current cultural backlash against progressive ideas, today’s debate on consciousness reflects our human fears of belonging to the same family as inanimate matter and losing our dear, transcendent souls. [...] The current debate on consciousness is influenced by our entrenched traditional ideas of ourselves"
Whose fear? Don't generalize, Carlo. These may be fears rooted in the modernist and Cartesian legacy, but they are only "traditional" if you think the world came into being during the 17th-18th century. Look back further and you find an Aristotelian and Thomistic view that also rejects metaphysical dualism. The soul here is the form of the body, which is to say, its formal cause. It isn't some ghost haunting a corpse or a puddle of ectoplasm. It is a principle. In this view, everything that is alive has a soul, which, again, is the name we give to the form of a living thing. Soul is just a class of form, and everything that exists has form.
What makes human beings different from other animals is, at the very least, that we possess intellects (and so, ontologically speaking, any embodied being with an intellect is human). The human intellect, according to this view, cannot be purely material, even if it relies on matter and even though it is united with bodily operations. The reason for this is that abstraction cannot occur in matter alone, as abstraction involves a mental operation of conceptual separation of the form of a thing as given in the senses. Matter (specifically what's called prime matter) is merely the principle of instantiation, and so it cannot "host" forms without instantiating that form. In other words, form + matter = thing.
"During the Middle Ages, Western civilization described humans as composed of two distinct entities: body and soul."
No that is not how people viewed the body and the soul in the Middle Ages (or in, say, Catholicism). That is a very Cartesian view of human beings, that we are two things, not one.
"The body was an interconnected bunch of matter that decayed and died. The soul belonged to a transcendent spiritual world independent from vile matter."
Matter wasn't vile, unless you were some kind of Gnostic or Cathar heretic or whatever. The physical was seen as good, as created by God, and human beings were understood as spiritual-corporeal unities that are by one nature both spiritual and physical. (The "spiritual" here has to do with the intellectual and free nature of man; again, not ectoplasm or ghosts). Indeed, if anything, Christianity elevated the dignity of the physical. Why bother with a resurrection after death if matter sucks? Why would the body and blood of Christ be so precious to Catholics if matter is evil? It is Gnostic dualism and similar movements that construed the physical as evil, but these were heretical movements, not views characteristic of the Middle Ages.
--
All that being said, I think the author would benefit greatly from a rigorous study of Aristotelian metaphysics, both to avoid these sorts of caricatures (as well as any misconceptions of science), but also to deepen his understanding. I think his rejection of dualism is on the right track, but he is missing out on a rich and robust intellectual tradition that has been sidelined by exactly those sorts of modernists that perpetuated this whole intellectual muddle in the first place.

Consider probing a midlevel mobile phone at some hundred contacts. You might be convinced to have a thorough account of the physical reality yet still no idea of (and no way to know) whats going on.
To the problem of qualia.. I think it's the mechanism of the brain to default-name recurring patterns, being part of a simplification/compression process, without which reasoning (computing) or reasonably storing experiences would be impossible. I guess visual qualia like color and shape have to be the first things the brain learns and attaches "default" symbols to. Consider other basic qualia too, like to be saturated, to feel warm and then higher qualia that build on these like to feel loved or accepted in a social community.
It's difficult to argue how there could be a fundamental truth to qualia. But consider that there'd be no difference in our communication, even if your red is attached to a symbol signified by 8NCYUW6D0H5C (lets just assume this) while my red is encoded as being GAUTP1P6YUUZ (those patterns obviously have to be encoded as frequency patterns as we perceive close colors as similar without computational overhead). Eventually it will turn out, qualia from person to person are encoded quite similar, as we are genetically so similar. But consider also synaesthetia. Wrt animals, it WOULD feel strange to be a bat or any other animal as some of their sensory apparatus is so different.
To this, author makes a good point: "Today, we do not have an exhaustive external account, but this is not the same as having proof that no such account is possible."
I imagine consciousness as 'theater mode' of the perceiving mind. As such it seems to be one part of the brain that integrates all sensory inputs into one Multimodal Experience Stream™.
As to TFA.. - I'm by no means up to date to the current affairs of the consciousness debate, but - is there really a "fierce debate [...] raging"?
Check out Joscha Bach who argues consciousness is an illusion. Looking for some material to back up, I hit on this text. Flying over it I already find it more enlightening than the posted article, so I post it here (without guarantee):

Some (citated) citations from it:
"The simulation becomes “more real than real” in our experience because it constitutes the entirety of our conscious access to ourselves and the world (Metzinger, 2003; Seth, 2021)."
"This perspective doesn’t diminish the richness or importance of conscious experience. On the contrary, it highlights the remarkable complexity and sophistication of the processes that generate our subjective experience. The constructed nature of consciousness isn’t a defect or limitation but a remarkable achievement — a way of making an unimaginably complex reality manageable for finite cognitive systems (Clark, 2016; Dennett, 2017)."

Why? It’s perfectly sane to just treat claims as is. You claim you’re a p-zombie, than you are. Claim you are conscious, than you are same as me. Claim you aren’t and you get no moral affordances, let’s see how long you last with that tactic.
Clankers are not conscious, good luck convincing me otherwise idiot.
Dont pretend like you dont believe anything is step 1.
In essence, consciousness is a complex information input-output system. When such a system reaches a certain level of complexity, it inevitably generates the concept of “I” as a way to simplify the processing of overwhelming information.
Praise be to AI. In 2025, inspired by AI, I feel that I have finally built a complete and unified worldview.
Are we living in a virtual illusion? Are there higher-dimensional rulers, gods, or immortals in the universe? What exactly are the human soul and consciousness?
I feel that these questions now share a single coherent answer. What I have written here is my answer regarding the soul and consciousness.
My life was wrecked by religious dogma, the type that is sustained on "big mysteries" and from there goes directly to imposing an odious recipe for life. So there is consolation to be had on seeing a big mystery crumble and on hearing the outcry. May another mystery crumble on my lifetime.
The hard question doesn't argue that consciousness is not a product of evolution. It probably is. It's just a question because we don't have a good way of explaining how/why it occurs.
It's that you can't even measure it, since the way it's defined as a subjective experience, no external measure could ever capture it. This is what gives rise to the p-zombie argument.
To get rid of that you have to accept "functional qualia" as basically equivalent to qualia, which solves the p-zombie issue and resolves half of the hard problem. From there, explaining consciousness is no "harder" than explaining other scale-depedent phenomenon in complex systems like LLMs: still hard, but at least tractable with scientific measurements and experiments.

I don't see how this is different from someone saying that a concoction of random ingredients will turn into a magic potion.
The big question is how a group of cells (or potentially something else) becomes sentient. Accepting "because it would be useful" as valid explanation would be the same as accepting Darwinism as a religion rather than science.
that's the easy problem
Quantum holography will someday demonstrate an analog information capacity of the quantum domain far exceeding the spin disposition.
Our minds use this domain by mass entanglement within our very own neurons.
You don’t want to hear it, though our minds may entangle and an entire culture exists among us who can traverse and manipulate the consciousness of others. They are responsible for the “voices in our heads”, and these are related to a great deal of very unscientific activity in our world.
All of that occult demonology you smarties scoff at yet plagues everyone embroiled in “power” is based upon this phenomena. We are not alone in our own minds, and more than a few of you will be forced to confront this at some point in your lives.
Falsifiable? Theories, not existential reality are concerned with what minds may falsify. Science lags behind reality, not the other way around.
