Looking at it “retrospectively” (ie: knowing the better answer), I disagree. “Emergence”, even if it moved at all, does not beget computation, and even if it did, it wouldn’t beget optimization, and even if it did… well then it might beget consciousness, but not without first going through computation and optimization.
So eliminating “emergence” is actually quite correct.
But there’s still the problem of noticing when you’re ignorant. Given the computational theory of mind, knowing that information is very likely built into the universe just like mass-energy (and that computation is thus built-in as well), it’s easy to look at someone getting the wrong answer and laugh at how wrong he is.
What’s harder is looking at a problem and noticing how you kinda-sorta have the tools to tackle it, but you don’t really.
I think you may be talking past one another. In Jim’s view as I understand it (and also, for what it’s worth, in mine) the computational physicalist theory of mind is a special case of “emergence”, and what’s wrong with “emergence” as an answer to the question “where does consciousness come from?” is not that it’s false but that it’s uninformative.
All “emergence” means on this reading is something like “consciousness is something that happens when the right sorts of physical processes do”, which I think is correct (at least as regards our consciousness; perhaps there could be non-physical processes that also produce consciousness; or perhaps not) and which I think is what Fodor says Strawson strenuously denies.
It’s like eating a tasty cake, and asking: “How did you make this cake?”, and receiving an answer: “It’s made of atoms.”
The answer is completely useless for cooking, and doesn’t explain anything about how the person actually made the cake. If someone is using this as an explanation in a cake-making course, they should be fired, because they don’t provide useful knowledge.
Technically, the answer remains true.
Also, consciousness has emerged from the interaction of atoms. But without more details, this answer is useless for any practical purpose. Yeah, there are atoms everywhere, and they interact all the time. Sometimes, consciousness emerges. Most of the time, it doesn’t. The important question is what makes the difference.
Luckily with consciousness, we have a broad idea of how it emerges: The processing of information (a physically measurable property) by certain structures with many feedback loops (particularly brains) causes the emergence of consciousness; and in particular saying that it’s emergent tells us that consciousness relates to the structure AND dynamics of the brain, and not to some intangible glob of soul attached to it.
So saying “emergence” plus the one sentence above actually gets us really far out of the land of mysticism.
This is a statement of materialism, not evidence or an argument that it is true.
The evidence for consciousness being a material phenomenon—the only evidence, as far as I can see—is the remarkable correspondence observed between physical brain phenomena and mental phenomena. But we have no knowledge of how matter produces consciousness. The hard example against which materialist woo (not all woo is mystical woo) generally fails is, “does this purported explanation predict the absence of consciousness in the cerebellum and motor control?”
ETA: Compare this with the materialist claim that the heart is a pump. Leonardo da Vinci could see that that it’s a pump just by dissecting it. We can see the mechanism, model it, show how electrical signals trigger the beats, understand dysfunctions like fibrillation, implant artificial pacemakers that work pretty well, and use external pumps to take over the function during heart surgery. We know how the heart works to produce the “emergent” property of pumping blood, and we can make pumps to perform the same function. All of this is so far missing from our knowledge of consciousness.
The evidence of the materialist view seems very strong to me; in particular, pretty much all of neuroscience bears it out; as you note there is:
the remarkable correspondence observed between physical brain phenomena and mental phenomena
And I disagree that it fails at
“does this purported explanation predict the absence of consciousness in the cerebellum and motor control?”
Comparative neuroscience between species or patients with certain types of brain damage really does give us a concrete idea of how “more complex” and “higher-order” cognition, at the very least part of the puzzle of consciousness, correlates with the presence of certain types of anatomical structures.
Is the brain much more complex than a pump? Sure. Does that mean that any hypothesis is anywhere near the purely materialist one? No. And even weird quantum effects, though there’s no strong evidence for them, still fall under the umbrella of materialism.
Just to be clear, I’m not arguing against materialism, just pointing out that we have no idea how it works.

A catalogue of brain regions that do correspond to conscious experience and those that do not does not amount to an explanation of how those that do, do, and those that don’t, don’t.
A catalogue of brain regions that do correspond to conscious experience and those that do not does not amount to an explanation of how those that do, do, and those that don’t, don’t.
Not just a catalogue; an understanding of their anatomical differences at the macroscopic and microscopic level, detailed studies of their electrical activities, and soon enough a neuron-level connectome to complement ever-more-fine-grained monitoring of electrical activity. This would provide the means to match more and more experiences to specific neuronal activity (or large complex—but still quantifiable—patterns of neuronal activity), including activities like deep introspection, meditation and creative work.
In the more distant future, a brain simulation that behaves like a person would be very strong evidence of the materialist view. If the only Chinese Room or Philosophical Zombie objections remain, then I’d consider the question of consciousness solved or at least dissolved.

You can make the same argument about radios or other devices that are relays for information. Without understanding how a radio works it’s really hard to know that the content that the radio plays isn’t an emergent phenomena.
You can make the same argument about radios or other devices that are relays for information. Without understanding how a radio works it’s really hard to know that the content that the radio plays isn’t an emergent phenomena.
When a radio is damaged, all that is affected is the clarity or the presence of the material that is being transmitted. There is no damage to a radio that would make spoken word material sound just the same, except that all nouns naming animals were garbled. The material coming over the radio has aspects to it that malfunctions of the radio may obscure but never manipulate.
In contrast, the correspondences found between brain damage and phenomena of consciousness suggest a very broad connection of the brain to the hypothetical soul, a connection so broad that there seems little work left for the soul to do. “Brain as the antenna of the soul” is at present looking very like “God in the gaps”.
I wouldn’t see the names of animals as phenomena of consciousness. I would rather label them mental phenomena.
I don’t know what distinction you’re drawing there. I cannot find different meanings to attach to the phrases “mental phenomena” and “phenomena of consciousness”.
Plenty of people meditate in an effort to raise their level of consciousness and transcend the mind that goes around and labels and judges.
I don’t know what “raise their level of consciousness and transcend the mind” means either. Labelling and judging are ordinary functions of the mind. I can grok that the name is not the thing without having to regard “naming” as some sort of newage sin.
I don’t know what “raise their level of consciousness and transcend the mind” means either.
That’s the point. If you are not familiar with the meaning of the terms that the other side of the debate uses, it’s hard to understand arguments.
Labelling and judging are ordinary functions of the mind.
The mind is generally considered as something distinct from consciousness by those people who meditate a lot and have developed a certain kind of self awareness in the process.
I don’t think that’s a gap of understanding that can be fixed easily, because it’s about gathering reference experiences.

Well, I have tried. None of the descriptions that I have read of the results of meditation match up to anything I have experienced. The various things I’ve read do not seem to agree with each other either. Do these people who meditate a lot even know what the others are talking about? Or am I looking at the equivalent of cryptozoologists describing the characteristics of the Loch Ness Monster?
Another point:
If you ask a bunch of people on this forum to describe what they mean with rationality, utility and uncertainty the descriptions that you will get are not identical. That doesn’t mean that those words have no meaning.
Talk about meditative experiences faces a difficulty not faced by those topics. We can all agree on what Bayes theorem and the VNM theorem are and that they are theorems, that the conjunction fallacy is a fallacy, that entanglement with reality is a necessary condition of acquiring knowledge about reality, and so on. There are open issues, such as whether utilitarianism, and if so what sort, is either descriptively or normatively sensible for humans or AIs, but it is easy to discuss such things and agree on what we are talking about, even if we do not agree about what is true about them. Even if we are drawing lines on our maps differently, we can discover that fact, and align them for the purposes of any particular discussion. LessWrong could not exist in the form it does if this were not so. Instead, it would be nothing more than Eliezer’s personal gurublog, and the bragging threads could not exist.
None of this is true of meditation.
Meditation explores the inside of one’s own mind. This is also something that objectively exists, but each person’s is private to them, and they cannot exhibit to anyone else what they find there, only talk about it in terms that may not map well to anyone else’s experience. There are no theorems, and few empirical observations to agree on, which makes it rich terrain for cultivating woo. As an anti-woo touchstone, “How does this putative guru lead his everyday life?” is a start, but doesn’t go beyond eliminating some of the junk. Is there any meditation forum that has a regular bragging thread, for people to announce the awesome things they did recently as a result of their practice? The mind boggles (but does so in a place where no-one else can see it).
One example of apparently differing experiences. A frequent observation made in what I have read is that the self is an illusion and with practice one can penetrate this illusion. That is the direct opposite of what I experience when I meditate. So, which of us is doing it wrong and becoming more mired in illusion, and which is doing it right and perceiving more accurately? This is not something I am willing to take an “outside view” on, i.e. to reject both my own experience, and the very idea of discovering the truth of the matter, in favour of going along with what other people say about theirs.
While I find the subject interesting, I have never yet found anything in other people’s material to repay that interest, even from the intersection of the meditative and rationalist communities.
Yes, you are right that talking about meditation is hard and might be harder than what we are doing here.
On the other hand imagine someone without any math background at all reading our discussions about Bayes theorem and the VNM theorem. Do you think that person would get the impression that we all basically agree?
On the other hand imagine someone without any math background at all reading our discussions about Bayes theorem and the VNM theorem. Do you think that person would get the impression that we all basically agree?
There’s plenty we do all agree on, such as what the VNM theorem says. And there are things we don’t, such as whether VNM implies we all really have utility functions. If someone is reading LessWrong without the background to meaningfully participate, that’s their problem, not ours. But they can solve that problem simply by reading up on the background, just as you or I can if some empirical subject comes up here that we aren’t familiar with.
But how would one get “up to speed” on the subject of meditation? I have read, I have practiced, I have meditated with others. But still, my experience does not join up with anyone else’s that I know of. I might as well be exploring a different continent. How many different continents are there in this space? Does anyone even know?
Imagine that human colour vision was highly polymorphic, with different people having different sets of colour receptors, sensitive to different wavelengths anywhere in the range from infrared to ultraviolet, and no one version being preponderant. Communicating what it is like to experience different colours would be difficult, but even there it would be easy to objectively demonstrate differences. Some people would, and some would not, be able to distinguish various pairs of objects. In the real world, how would one go about testing a hypothesis of mental polymorphism?
I personally started with meditation 10 years ago by reading a book from the Aikido master Tohei. It was good enough that I continued the practice from time to time.
Two and a half years ago I started attending group for somatic-psychoeducation regularly. It’s a framework developed by a Frenchman called Danis Bois. The interesting thing about Danis is that even being accomplished in teaching meditation and bodywork he thought that a lot of the esoteric crowd was too dogmatic and close minded so he went to university studying academic pedagogy. He’s now a professor at a Portuguese university.
I learned a lot in those 2 1⁄2 years. When I read the book that supposed to be an introduction into the method half a year into it, I couldn’t do much with it. Now the book makes more sense. I do know from experience that the process isn’t easy. This year I think I got a grasp about what Buddhist might mean when they say Karma and how Karma fits into a framework where everything is to be supposed to be accessible through direct experience.
If you can find someone doing somatic-psychoeducation I recommend it, but quick Googling shows nobody in Norwich.
As far as the Indian tradition goes, they do something called Satsang. Good satsang teachers usually have a kind of charisma that the average person can perceive and that’s impressive to some people who do feel emotions naturally. If you aren’t neurotypical get a neurotypical person along to see whether they feel the charisma. A teacher without his own spiritual experience who just reiterated what he read somewhere won’t have that charisma.
If you can find a good Satsang session sitting in and asking questions with a goal of trying to predict answers, might be a good way to learn the framework even if you don’t completely take it for yourself.
I don’t subscribe to perennialism according to which all spiritual tradition say the same thing. At the same time there are things that are common over multiple traditions.
As far as written descriptions go, a written description of the nature of the color red doesn’t give a blind person a real idea of what red looks like even when it’s written in braille.
I don’t think that any decent spiritual tradition works simply through reading descriptions. Most have a least some instance of teaching via questions & answers.
You can make the same argument about radios or other devices that are relays for information. Without understanding how a radio works it’s really hard to know that the content that the radio plays isn’t an emergent phenomena.
I do not get this analogy. We know quite a bit about how the brain work at the neuronal level. A rigorous program of research exists that should gives us an understanding of increasingly coarse modules over time. Simulating a brain in silico is an eventually-achievable method to extensively test almost any hypothesis we could develop.
When I say consciousness is emergent I’m saying that I believe neuroscience will eventually be able to pinpoint the mechanisms of almost any type of higher-order thought, and come up with as-useful-as-is-possible a definition of things like qualia and self-awareness, and that these mechanisms will all relate to complex, dynamic neuronal and chemical behavior in the brain.
An example non-emergent explanation of consciousness would be “the brain is an antenna for ethereal souls”, which would be hard to test but would have to be given consideration if the program I outline above completely fails to fully account for thoughts and experiences above a certain complexity.
Simulating a brain in silico is an eventually-achievable method to extensively test almost any hypothesis we could develop.
You just assume that’s true. Before we actually do run that simulation in practice we don’t know whether that’s true.
When I say consciousness is emergent I’m saying that I believe neuroscience will eventually be able to pinpoint the mechanisms of almost any type of higher-order thought
Yes, and other people do believe in souls and God. We don’t have evidence that proves either hypothesis.
An example non-emergent explanation of consciousness would be “the brain is an antenna for ethereal souls”, which would be hard to test but would have to be given consideration if the program I outline above completely fails to fully account for thoughts and experiences above a certain complexity.
Yes, and the brain as an antenna hypothesis is basically what parapsychologists like Dean Radin advocate these days. We don’t have yet evidence to prove it wrong.
Saying we could in theory run experiments that if those experiments turn out a certain way would prove our theory right is not the same thing as arguing that there evidence for your theory.
Science lives from distinguishing what you know and what you don’t know.
I am making predictions, but they are predictions that a concrete, existing program of research (the field of neuroscience) is trying to test.
I obviously can’t conjure this evidence out of thin air, because it doesn’t yet exist (and, sure, may never exist). But I am outlining why I believe that calling consciousness emergent is a perfectly valid, predictive hypothesis in the context of neuroscience (saying ‘phenomena X is emergent’ is, I believe, not an empty statement at all but instead more-or-less equivalent to saying “The question ‘What singular external thing causes phenomena X’ should be dissolved’; with panpsychism being the anti-emergent hypothesis in this case).
And I also believe that emergent consciousness is more likely to be the correct view, and I hope I’ve given clear reasons why that’s so.
If I made an in silico simulation of a human brain that could convincingly match human cognition, what would stop you from believing that it was also conscious?
I wouldn’t say it wasn’t and I wouldn’t say it was.
A functional duplicate of a qualiaphile would report qualia, even if it didn’t have them, and a functional duplicate of a qualiaphobe would deny it had qualia even if it did.
Eta:
In other words, everything is predictable from who’s brain is emulated. We need some other test.
Still, isn’t “emerges” even there a shortcut for “then it somehow happens… but I don’t know how specifically”?
To rephrase what you wrote:
If information is processed by certain structures with many feedback loops (like brains) then… sometimes… I am not sure what specific conditions are necessary… consciousness happens.
Of course it feels much less convincing when written this way. As it should. Because it honestly admits that I actually don’t know the details, and maybe some critical part is still missing.
Concretely, this hypothesis tells us to look at physical structures and neuronal activity in the brain and compare them across individuals and species, and that this
The field of neuroscience seems to bear this out. Our perceptions and emotions are accounted for by brain activity. Seemingly deeper issues like memory formation and temporal perception, have been successfully localized and understood to a great degree.
In particular, even though we don’t understand there’s no obvious gaps. The phenomena we still don’t understand seem hard to understand because they are high-level or occur very diffusely, not because they aren’t generated by the activity of neurons in the brain (hypothetical contradictory evidence would be people reporting some type of highly distinctive experience [say out-of-body, or less mystically deja vu] while an MRI shows no deviation from normal resting activity).
By perceptions I mean our senses and by emotions I mean broad emotions like sadness, anger and excitement.
These sorts of lower-level experiences, which are also present in animals, are fully accounted for, correlated with AND explained by neural and chemical activity in the brain. By reading the electrical activity of your neurons, I could figure out what you were seeing. By electrically stimulating a certain part of the brain, I could make you feel angry or happy or sad.
This level of deep mechanistic understanding seems to be coming for other phenomena, but yes that is a prediction of the future so no I can’t prove it right this second.
Looking at it “retrospectively” (ie: knowing the better answer), I disagree. “Emergence”, even if it moved at all, does not beget computation, and even if it did, it wouldn’t beget optimization, and even if it did… well then it might beget consciousness, but not without first going through computation and optimization.

The comment has about emergentism, but your reply was about soul theory, which is quite different.
Strong emergentism is notoriously badly defined, but a typical version might include:
1 mental phenomena are irreducible, or have an irreducible component
2 mental phenomena are not predictable from neural activity by standard physical laws
3 mental phenomena phenomena are related to neural activity by special psychophysical laws
Note that 3 guarantees a close relationship between neural activity and consciousness.

Is anyone claiming to have found any yet?
No, but that’s another issue, again.
I do not get this analogy. We know quite a bit about how the brain work at the neuronal level. A rigorous program of research exists that should gives us an understanding of increasingly coarse modules over time. Simulating a brain in silico is an eventually-achievable method to extensively test almost any hypothesis we could develop.
When I say consciousness is emergent I’m saying that I believe neuroscience will eventually be able to pinpoint the mechanisms of almost any type of higher-order thought, and come up with as-useful-as-is-possible a definition of things like qualia and self-awareness, and that these mechanisms will all relate to complex, dynamic neuronal and chemical behavior in the brain.
An example non-emergent explanation of consciousness would be “the brain is an antenna for ethereal souls”, which would be hard to test but would have to be given consideration if the program I outline above completely fails to fully account for thoughts and experiences above a certain complexity.
You just assume that’s true. Before we actually do run that simulation in practice we don’t know whether that’s true.
Yes, and other people do believe in souls and God. We don’t have evidence that proves either hypothesis.
Yes, and the brain as an antenna hypothesis is basically what parapsychologists like Dean Radin advocate these days. We don’t have yet evidence to prove it wrong.
Saying we could in theory run experiments that if those experiments turn out a certain way would prove our theory right is not the same thing as arguing that there evidence for your theory.
Science lives from distinguishing what you know and what you don’t know.
I am making predictions, but they are predictions that a concrete, existing program of research (the field of neuroscience) is trying to test.
I obviously can’t conjure this evidence out of thin air, because it doesn’t yet exist (and, sure, may never exist). But I am outlining why I believe that calling consciousness emergent is a perfectly valid, predictive hypothesis in the context of neuroscience (saying ‘phenomena X is emergent’ is, I believe, not an empty statement at all but instead more-or-less equivalent to saying “The question ‘What singular external thing causes phenomena X’ should be dissolved’; with panpsychism being the anti-emergent hypothesis in this case).
And I also believe that emergent consciousness is more likely to be the correct view, and I hope I’ve given clear reasons why that’s so.
You’re using “emergent” to mean “reductiomistic”, which is pretty much the opposite
I think you don’t understand what emergent means. Traffic jams emerge from individual drivers’ behavior for instance.
Emergent has more than one meaning.
Are you actually confused by my terminology (in which case I’ll clarify) or are you just being pedantic?
I am pointing out something which may stop you getting into pointless discussions with people who use the word differently.
Cognition is the Easy Problem.
If I made an in silico simulation of a human brain that could convincingly match human cognition, what would stop you from believing that it was also conscious?
I wouldn’t say it wasn’t and I wouldn’t say it was.
A functional duplicate of a qualiaphile would report qualia, even if it didn’t have them, and a functional duplicate of a qualiaphobe would deny it had qualia even if it did.
Eta:
In other words, everything is predictable from who’s brain is emulated. We need some other test.
Still, isn’t “emerges” even there a shortcut for “then it somehow happens… but I don’t know how specifically”?
To rephrase what you wrote:
Of course it feels much less convincing when written this way. As it should. Because it honestly admits that I actually don’t know the details, and maybe some critical part is still missing.
It’s incomplete, but that’s okay.
Concretely, this hypothesis tells us to look at physical structures and neuronal activity in the brain and compare them across individuals and species, and that this
The field of neuroscience seems to bear this out. Our perceptions and emotions are accounted for by brain activity. Seemingly deeper issues like memory formation and temporal perception, have been successfully localized and understood to a great degree.
In particular, even though we don’t understand there’s no obvious gaps. The phenomena we still don’t understand seem hard to understand because they are high-level or occur very diffusely, not because they aren’t generated by the activity of neurons in the brain (hypothetical contradictory evidence would be people reporting some type of highly distinctive experience [say out-of-body, or less mystically deja vu] while an MRI shows no deviation from normal resting activity).
“Accounted for” is ambiguous between “correlated with”, and “explained by”.
By perceptions I mean our senses and by emotions I mean broad emotions like sadness, anger and excitement.
These sorts of lower-level experiences, which are also present in animals, are fully accounted for, correlated with AND explained by neural and chemical activity in the brain. By reading the electrical activity of your neurons, I could figure out what you were seeing. By electrically stimulating a certain part of the brain, I could make you feel angry or happy or sad.
This level of deep mechanistic understanding seems to be coming for other phenomena, but yes that is a prediction of the future so no I can’t prove it right this second.
Train a blind from birth person in your technique.
Hand them a braille readout of the neural activity of someone looking at a tomato.
Would they now know how red the things look to a sighted person?
Yes, they could easily tell the distribution of color receptor activation.
Not what I asked.
Then what are you asking. Please, precisely define what it would mean to “know how red the things look”.
Look at a tomato.
That’s how a red thing looks.
