I’m not sure what you mean. Qualia clearly exist. You’re having them right now. Whatever they are, they’re also “components of programs”. That’s just what qualia look like from the outside—there is no separation. I am by no means a dualist—I think consciousness and information processing are the same exact thing.
I’m not convinced that statements like “qualia clearly exist” are informative. It feels like a ‘poisoned idea’, e.g. because of the connection with ‘p-zombies’.
AFAICT, qualia isn’t equivalent to, e.g. being able to ‘see’ or perceive the ‘color red’ (i.e. distinguish ‘red’ from other possible ‘colors’). It’s something else – the ‘quality of redness’.
It seems like people are referencing their feelings, from ‘the inside’, but also claiming that there isn’t any way to ‘externally observe’ from ‘the outside’ whether any particular entity has qualia.
It seems to me to be too suspiciously reliant on communication via human language.
But, to the degree that ‘qualia clearly does exist’, I wouldn’t expect it to also be the kind of thing that either ‘exists’ (in some entity) or doesn’t.
Do cockroaches have qualia? Do bacteria? Viruses? Rocks?
If “consciousness and information processing are the same exact thing” what do you think is a ‘rough OOM’ of “information processing” that implies qualia?
If there is evidence for qualia, you should believe in qualia, irrespective of the consequences. The “poisoned idea” idea suggests that it’s OK to reject evidence in order to preserve theories. In the form of “fossils were created by the devil to delude people”, that’s the height of irrationallity.
‘Evidence’ doesn’t imply any particular degree of certainty, e.g. “should believe”.
But I wasn’t in fact denying the existence of qualia as much as thinking that we’re ‘confused’ about the thing we’re gesturing at, hence the ‘poison’.
I agree that there seems like something ‘special’ about, e.g. why the color ‘red’ also ‘looks red’ (and maybe ‘looks’ differently to someone else). But I’m (thoroughly) confused about whether it is special, or whether it’s natural and expected, ‘from the inside’, for any sentience/consciousness to think that (without it also being necessarily ‘true’).
I’m not even sure that what I think is my own qualia is what other people mean by ‘qualia’! How could I know? It seems like the only way for ‘qualia’ to even possibly be referring to the same thing is via communication with and among similar beings as myself.

That means you don’t have an explanation of qualia. Which is fine, you are not supposed to. But lacking an explanation is not a good reason to reject the whole topic.
I’m not even sure that what I think is my own qualia is what other people mean by ‘qualia’
The same could be said of terms like “consciousness” and ” sentience”, yet you have been using them. In fact, the term. “Qualia” comes from an attempt to clarify “consciousness” .
That means you don’t have an explanation of qualia. Which is fine, you are not supposed to. But lacking an explanation is not a good reason to reject the whole topic.
That’s not my only evidence for why it might be sensible to “reject the whole topic”. I would expect a good explanation, if one existed, to be NOT confusing for LOTS of people, not just its proponents.
I suspect that it’s the kind of confusion where we (eventually) realize that ‘qualia is a thing’ isn’t ‘even wrong’.
My current very-tentative/very-weakly-held hypothesis for ‘qualia’ is that it’s nothing in particular, i.e. that there’s no sharp delineation between ‘qualia’ and ‘information processing’ (‘computation’) or ‘things with qualia’ and ‘things without qualia’.
I think we can in fact look at other entities, ‘from the outside’, and make reliable estimations as to their likely ‘qualia’. I think ‘having qualia’ is ‘sentience’ and that sentience is a spectrum spanning (at least):
Photons – basically no qualia
Rocks – also basically no (interesting/complicated) qualia
Viruses and rocks – a kind of ‘minimal’ qualia maybe? They do seem to have a minimal degree of sensation/perception[^1] and, being ‘life’ (maybe), they do have a kind of un-conscious/fixed/hard-coded memory/history that they encode/‘remember’
Lots of animals – definitely some kind/degree-of-quality of qualia. Lots seem able to track and predict other entities and have some kind of ‘temporal qualia’ maybe too. They also seem to mostly have ‘real’ memory that isn’t encode/fixed/hard-code, e.g. in their DNA.
Animals with communication – ‘social qualia’
Us and maybe a few other species? – ‘conscious qualia’, i.e. ‘self-aware qualia’
I’m guessing that ‘consciousness’ starts at [5] – with basically any kind of communication, i.e. being able to be any kind of a ‘storyteller’.
I think we – and maybe some other species – are at the ‘next level’ because our communication is ‘universal’ in a way that other animal’s communications are more static/fixed/repeating/nested, but not more complicated than that.
[^1] I can’t see much of a definite clear line delineating/classifying/categorizing ‘sensation’ versus ‘perception’. They both just like a ‘kind of computation’ we can somewhat reliably recognize.
That’s not my only evidence for why it might be sensible to “reject the whole topic”. I would expect a good explanation, if one existed, to be NOT confusing for LOTS of people, not just its proponents.
Theres not supposed to be a good explanation of qualia , in terms of what they are and how they work. “Qualia” is supposed to point to the heart of the problem of consciousness. There may also be confusion about what “qualia” points to as a prima facie evidence … but it may be motivated, not genuine.
My current very-tentative/very-weakly-held hypothesis for ‘qualia’ is that it’s nothing in particular, i.e. that there’s no sharp delineation between ‘qualia’ and ‘information processing’ (‘computation’) or ‘things with qualia’ and ’things without qualia
You are doing that thing of treating qualia as objective, when they are supposed to be subjective. It makes a big difference to you whether you have surgery under anesthesia or not.
Yes, I defy the assumption that qualia are “supposed to be subjective”. I would expect ’having surgery under anesthesia or not” to not be entirely subjective.
How do you know if you don’t what “qualia” means?
What do you mean by “know”?
I think that what other people mean when they say or write ‘qualia’ is something like ‘subjective experience’.
I think ‘having qualia’ is the same thing as ‘sentience’ and I think ‘sentience’ is (roughly) ‘being a thing about which a story could be told’. The more complex the story that can be told, the more ‘sentience’ a thing has. Photons/rocks/etc. have simple stories and basically no sentience. More complex things with more complex sensation/perception/cognition have more complex stories, up to (at least) us, where our stories can themselves contain stories.
Maybe what’s missing from my loose/casual/extremely-approximate ‘definition’ of ‘sentience’ is ‘perspective’. Maybe what that is that’s missing is something like a being with qualia/sentience being ‘a thing about which a story could be told – from its own perspective’, i.e. a ‘thing with a first-person story’.
‘Subjective experience’ then is just the type of the elements, the ‘raw material’, from which such a story could be constructed.
For a person/animal/thing with qualia/sentience:
Having surgery performed on them with anesthesia would result in a story like “I fell asleep on the operating table. Then I woke up, in pain, in a recovery room.”
Having surgery without anesthesia would (or could) result in a story like “I didn’t fall asleep on the operating table. I was trapped in my body for hours and felt all of the pain of every part of the surgery. …”
I don’t think there’s any good reason to expect that we won’t – at least someday – be able to observe ‘subjective experiences’ (thus ‘sentience’), tho the work of ‘translating’ between the experiences of ‘aliens’ and the experiences of people (humans) can be arbitrarily difficult. (Even translating between or among humans is often extremely difficult!)
In this extremely-rough model then, ‘consciousness’ is the additional property of ‘being able to tell a story oneself’.
Theres not supposed to be a good explanation of qualia
That’s a perfect example of why it seems sensible to “reject the whole topic”.
I’ve already explained why that’s an anti pattern. If you had rejected the very idea of magnetism when magnetism wasn’t understood, it would not now be understood. Or meteorites, which actually were rejected for a while.
That’s just picking ‘worship’ instead of ‘explain’.
There’s not supposed to be a good explanation of qualia currently.
Qualia aren’t supposed to be inexplicable, just unexplained. It’s not like there are just two states “hopeless woo” and “fully explained right now”.
Yes, I defy the assumption that qualia are “supposed to be subjective”. I would expect ’having surgery under anesthesia or not” to not be entirely subjective.
So it’s still subjective, so long as subjective means “not entirely objective”.
I don’t think there’s any good reason to expect that we won’t – at least someday – be able to observe ’subjective experience
Who said otherwise? You seem to have decided that “qualia are subjective experiences and we don’t understand them” means something like “qualia are entirely and irredeemably subjective and will be a mystery forever”.
It’s almost always the case that claims come in a variety of strengths … But outgroup homogeneity bias will make and it seem like your outgroup all have the same, dumb claim. If you are attacking the most easily attackable form of qualiaphilia, you are weakmanning.
Maybe we will have qualiometers one day, and maybe we will abandon the very idea of qualia. But maybe we won’t, so we have no reason to treat qualia as poison now.
I’ve already explained why that’s an anti pattern. If you had rejected the very idea of magnetism when magnetism wasn’t understood, it would not now be understood.
I’m rejecting the idea of ‘qualia’ for the same reason I wouldn’t reject the idea of magnetism – they both seem (or would seem, for magnetism, in your hypothetical).
I’m rejecting ‘mysterious answers’, e.g. “Theres not supposed to be a good explanation of qualia”.
Who said otherwise? You seem to have decided that “qualia are subjective experiences and we don’t understand them” means something like “qualia are entirely and irredeemably subjective and will be a mystery forever”.
Sorry – that’s not what I intended to convey. And maybe we’re writing past each other about this. I suspect that ‘qualia’ is basically equivalent to something far more general, e.g. ‘information processing’, and that our intuitions about what ‘qualia’ are, and the underlying mechanics of them (of which many people seem to insist don’t exist), are based on the limited means we have of currently, e.g. introspecting on them, communicating with each other about them, and weakly generalizing to other entities (e.g. animals) or possible beings (e.g. AIs).
I also suspect that ‘consciousness’ – which I’m currently (loosely/casually) modeling as ‘being capable of telling stories’ – and us having consciousness, makes thinking and discussing ‘qualia’ more difficult than I suspect it will turn out to be.
Maybe we will have qualiometers one day, and maybe we will abandon the very idea of qualia. But maybe we won’t, so we have no reason to treat qualia as poison now.
What I’m (kinda) ‘treating as poison’ is the seemingly common view that ‘qualia’ cannot be explained at all, i.e. that it’s inherently and inescapably ‘subjective’. It sure seems like at least some people – tho maybe not yourself – are either in the process ‘retreating’, or have adopted a ‘posture’ whereby they’re constantly ‘ready to retreat’, from the ‘advances’ of ‘objective investigation’ and then claim that only the ‘leftover’ parts of ‘qualia’ that remain ‘subjective’ are the ‘real qualia’.
I’m rejecting the idea of ‘qualia’ for the same reason I wouldn’t reject the idea of magnetism – they both seem (or would seem, for magnetism, in your hypothetical)
Seem what?
I’m rejecting ‘mysterious answers’, e
The lack of explanation for qualia is not intended as an answer.
I suspect that ‘qualia’ is basically equivalent to something far more general, e.g. ‘information processing’,
If you could show that , that would be an explanation. Staring that an A is, for no particular reason, a B is not explanation.
What I’m (kinda) ‘treating as poison’ is the seemingly common view that ‘qualia’ cannot be explained at all
You say it is common , but no one in this discussion has made it , and you haven’t named anyone who has made it. And inexplicability is not part of the definition of “qualia”.
Winding back:-
I’m not convinced that statements like “qualia clearly exist” are informative. It feels like a ‘poisoned idea’, e.g. because of the connection with ‘p-zombies’.
Theres nothing about inexplicability there , either. But there is something about wrongthought ,.ie.zombies.
So it’s still subjective, so long as subjective means “not entirely objective”.
Everything in the universe is (arguably) physical—there is nothing that exists that’s not entirely objective and entirely accessible to external inquiry.
To the extent that qualia are subjective, their subjectivity needs to be an entirely objective property—otherwise it wouldn’t exist.
Everything in the universe is (arguably) physical—there is nothing that exists that’s not entirely objective and entirely accessible to external inquiry.
That’s true only if the evidence supports it.
To the extent that qualia are subjective, their subjectivity needs to be an entirely objective property—otherwise it wouldn’t exist.
That’s the opposite of rationality. In rationality, evidence determines theories,not vice versa.
I actually am a panpsychist. I literally mean that all information processing is consciousness. I even sort of suspect that consciousness and irreversible processes might be identical, even more generally, and that literally everything that occurs is a physical process from the outside and a conscious experience from the inside—but most of those “insides” lack memory, agency, etc and are just flashes of awareness without continuity, like extremely deep sleep, which is basically unimaginable to humans and of minimal moral relevance. But that’s my opinion; I can’t possibly prove it of course.
So, complexity of qualia, together with continuity as some kind of coherent “entity”—which appears to rely somehow on complexity of data structures being manipulated over time in a single substrate, with every processing element causally linked to some extent with all the others, that isn’t changing “too quickly” (for some unknown value of “too”—is someone the same person after resuscitation from brain death? I don’t know) - would then be the correlate of moral relevance, and I think that itself correlates very, very roughly with number of synapses or synapse-like objects (meaning that some plants may score higher than animals without nervous systems such as oysters, given the existence of the “root brain” and various other developments in plant cognition science).
More specifically I think Integrated Information Theory is at least part of the way there (it’s not really synapses directly so much as the state spaces generated by the whole brain’s activities), and the Qualia Research Institute’s hypotheses (which compare brain states to acoustic waves and suggest that “consonance” and “dissonance” may correspond to high and low valence) show some promise. Probably both are ultimately wrong and reality is far stranger than we expect, but I think they’re also both in the right general vicinity.
I think I’m now (leaning towards being) a ‘panpsyhcist’ but in terms of equating information processing with sentience, not ‘consciousness’.
‘Consciousness’ is ‘being a storyteller’.
A (VERY rough) measure of ‘sentience’ tho is ‘what kind of stories can we tell about what it’s like to be a particular thing’. The ‘story’ of a photon, or even a rock, is going to be much simpler than the same thing for a bacterium or a human. (It’s not obvious tho that we might ‘miss’ some, or even most, ‘sentience’ because it’s so alien to our own experiences and understanding.)
I don’t think ‘consciousness’ can exist without ‘temporal memory’ and ‘language’ (i.e. an ability to communicate, even if only with oneself).
So, along these lines, non-human primates/apes probably are somewhat conscious. They can tell ‘lies’ for one. Evidence for their consciousness being more limited than our own is that the ‘stories they tell’ are much simpler than ours.
But I think one nice feature of these ideas is that it seems like we could in fact discern some facts about this for particular entities (via ‘external observation’), e.g. test whether they do have ‘temporal memory’ or language (both evidence of ‘consciousness’) or whether they have ‘experiences’ and respond to features of their environment (which would be evidence of ‘sentience’).
I’m with you on information being key to all of this.
We’re using words differently. When I say “consciousness”, I mean “there being something which it is like to be a thing”, which I think you mean by “sentience.” What I would call the thing you call “consciousness” is either “sapience” or “sophonce”, depending on whether you consider self-awareness and agency an important part of the definition (sophonce) or not (sapience). The difference is that I expect tool / non-agentive AGIs to be sapient (in that they can think abstractly), but not sophont (they are not “people” who have an identity and will of their own).
“There being something which it is like to be this thing” is a characteristic I consider likely to be possessed by all systems which are “processing information” in some way, though I am unsure exactly what that means. It certainly seems to be something all living things possess, and possibly some nonliving ones—for instance, it has recently been demonstrated that neural networks can be simulated using the acoustics of a vibrating metal sheet (I read about it in Quanta, I’ll give you a link if you want but it shouldn’t be hard to find), meaning that for the duration that they are being used this way, they (or rather, the algorithm they are running) are as conscious as the network being simulated would be.
I think that photons do not have this characteristic—they are not sentient in your terms—because they aren’t interacting with anything or doing anything as they float through the aether. Possibly sparks of qualia exist when they interact with matter? But I don’t know the physical details of such interactions or whether it is possible for a photon to remain “the same photon” after interacting with other matter—I expect that it is a meaningless concept—so there would be no continuity of consciousness / sentience whatsoever there—nothing remotely resembling a being that is having the experience.
A rock on the other hand maybe would have a rather continuous experience, albeit unimaginable to us and extremely simple, due to the coherence of its physical form and the fact that acoustic vibrations (which maybe are a kind of computation or information processing, in a sense?) are traversing it. But if information processing means something more than that, then rocks wouldn’t either. I’m really not sure about all that.
Yeah, my current personal definitions/models of ‘consciousness’ and ‘sentience’ might be very idiosyncratic. They’re in flux as of late!
I think photons are more complicated than you think! But I also don’t think their ‘sentience’ is meaningfully different than from a rock. A rock is much bigger tho, and you could tell ‘stories’ of all the parts of which it’s made, and I would expect those to be similar to the ‘stories’ you could tell about a photon; maybe a little more complicated. But they still feel like they have the same ‘aleph number’ in ‘story terms’ somehow.
I think what separates rocks from even viruses, let alone bacteria, is that the ‘stories’ you could tell about a rock are necessarily and qualitatively simpler, i.e. composed of purely ‘local’ stories, or for almost all parts. The rock itself tho is, kinda, in some sense, a memory of its history, e.g. ‘geological weathering’.
It’s hard to know, in principle, whether we might be missing ‘stories’, or sentience/consciousness/qualia, because those stories are much slower than ours (or maybe much faster too).
Viruses, bacteria, and even probably the simplest possible ‘life prototypes’ all seem like they’re, fundamentally, ‘just’ a kind of memory, i.e. history.
‘Rocks’ have stories composed of statis, simple fixed reactions, and maybe sometimes kinds of ‘nested explosions’ (e.g. being broken apart into many pieces).
‘Life’ has a history – it IS a history, copying itself into the future. It’s on ‘another level’ (‘of ontology’? of ‘our ontology’?) because it’s the kid of thing capable of ‘universal computation’ based on molecular dynamics.
We’re a kind of life capable of cognitive (and cultural) ‘universal computation’ – there might be a LOT of this kind of life beyond our own species; maybe most things with something like a brain or even just a nervous system? Humans do seem ‘programmable’ in a way that almost everything else seems ‘hard-coded’. Some other animals do seem to have some limited programmability; maybe not ‘universal programmability’ tho?
I think we (humans) are, or many of us anyways, ‘universally programmable’ via, e.g. culture, or (‘conscious’) ‘reasoning’.
A definition of ‘sentient’:
able to perceive or feel things.
‘Perceive’ seems relatively ‘sharp’ for us; and this site generally. (Do you disagree?)
‘Feel’ I think could be helpfully sharpened to ‘can react to specific things’. I think it’s sensible to think that we can ‘feel’ things that we’re not consciously aware of. (We probably can’t consciously report those feelings tho! Or not easily.)
Tho maybe ‘feel’ reasonably requires ‘consciousness’, i.e. the ability to tell a story about feelings, i.e. tell a story about our internal subjective experience.
I think it makes sense for us to tell a story about a, e.g. lion, being ‘scared’ or ‘afraid’ while being attacked by a pack of wild dogs. I’m less sure that it makes sense to think that the lion itself ‘feels’ those emotions? What do we, what could we, mean by that?
I don’t think there’s any evidence that lions can themselves ‘tell a story’ that mentions that fear. I wouldn’t guess that there’s anything going on in the lion’s brain/mind that’s at all like telling itself “Oh shit oh shit oh shit”. I don’t think there’s anything remembering the fear, and its context, or any of the relevant associations. I don’t think it’s just that we can’t know whether the lion ‘feels’, from ‘the outside’, because the lion can’t communicate with us. I don’t think the lion can communicate the fact of its specific fear to other lions either. Nor do I think it can ‘tell itself’ of that specific fear.
It ‘feels’ the fear, but afterwards that fear is ‘gone’. (The effects of that fear can of course persist, even in its brain/mind. But there’s no ‘pointer’ to or memory of that specific fear anywhere in particular.)
I think consciousness is basically ‘being able to tell a story’ and it’s just a kind of ‘convergent inevitability’ that we should generally expect consciousness to also entail/imply ‘being able to tell a story about itself’, and thus also ‘know of itself as a thing in the World’.
The historical connection between “qualia” and the p-zombie thought experiment is extremely unfortunate IMO. We did not need a new term for experience, especially when we already had “phenomenon”.
I’m not sure what you mean. Qualia clearly exist. You’re having them right now. Whatever they are, they’re also “components of programs”. That’s just what qualia look like from the outside—there is no separation. I am by no means a dualist—I think consciousness and information processing are the same exact thing.

Evidence implies updating by a non zero amount.

I suspect that ‘qualia’ is basically equivalent to something far more general, e.g. ‘information processing’, and that our intuitions about what ‘qualia’ are, and the underlying mechanics of them (of which many people seem to insist don’t exist), are based on the limited means we have of currently, e.g. introspecting on them, communicating with each other about them, and weakly generalizing to other entities (e.g. animals) or possible beings (e.g. AIs).
I also suspect that ‘consciousness’ – which I’m currently (loosely/casually) modeling as ‘being capable of telling stories’ – and us having consciousness, makes thinking and discussing ‘qualia’ more difficult than I suspect it will turn out to be.
What I’m (kinda) ‘treating as poison’ is the seemingly common view that ‘qualia’ cannot be explained at all, i.e. that it’s inherently and inescapably ‘subjective’. It sure seems like at least some people – tho maybe not yourself – are either in the process ‘retreating’, or have adopted a ‘posture’ whereby they’re constantly ‘ready to retreat’, from the ‘advances’ of ‘objective investigation’ and then claim that only the ‘leftover’ parts of ‘qualia’ that remain ‘subjective’ are the ‘real qualia’.
Seem what?
The lack of explanation for qualia is not intended as an answer.
If you could show that , that would be an explanation. Staring that an A is, for no particular reason, a B is not explanation.
You say it is common , but no one in this discussion has made it , and you haven’t named anyone who has made it. And inexplicability is not part of the definition of “qualia”.
Winding back:-
Theres nothing about inexplicability there , either. But there is something about wrongthought ,.ie.zombies.
Everything in the universe is (arguably) physical—there is nothing that exists that’s not entirely objective and entirely accessible to external inquiry.
To the extent that qualia are subjective, their subjectivity needs to be an entirely objective property—otherwise it wouldn’t exist.
That’s true only if the evidence supports it.
That’s the opposite of rationality. In rationality, evidence determines theories,not vice versa.
So, for that to be otherwise, people would need to find that the (human) brain breaks the laws of physics. Otherwise it’s true.
Fundamental subjectivity can exist without breaking physics.
But not subjectivity that wouldn’t be fully objective at the same time.
Subjectivity that is not also objectivity is what I meant by fundamental subjectivity.
I actually am a panpsychist. I literally mean that all information processing is consciousness. I even sort of suspect that consciousness and irreversible processes might be identical, even more generally, and that literally everything that occurs is a physical process from the outside and a conscious experience from the inside—but most of those “insides” lack memory, agency, etc and are just flashes of awareness without continuity, like extremely deep sleep, which is basically unimaginable to humans and of minimal moral relevance. But that’s my opinion; I can’t possibly prove it of course.
So, complexity of qualia, together with continuity as some kind of coherent “entity”—which appears to rely somehow on complexity of data structures being manipulated over time in a single substrate, with every processing element causally linked to some extent with all the others, that isn’t changing “too quickly” (for some unknown value of “too”—is someone the same person after resuscitation from brain death? I don’t know) - would then be the correlate of moral relevance, and I think that itself correlates very, very roughly with number of synapses or synapse-like objects (meaning that some plants may score higher than animals without nervous systems such as oysters, given the existence of the “root brain” and various other developments in plant cognition science).
More specifically I think Integrated Information Theory is at least part of the way there (it’s not really synapses directly so much as the state spaces generated by the whole brain’s activities), and the Qualia Research Institute’s hypotheses (which compare brain states to acoustic waves and suggest that “consonance” and “dissonance” may correspond to high and low valence) show some promise. Probably both are ultimately wrong and reality is far stranger than we expect, but I think they’re also both in the right general vicinity.
I think I’m now (leaning towards being) a ‘panpsyhcist’ but in terms of equating information processing with sentience, not ‘consciousness’.
‘Consciousness’ is ‘being a storyteller’.
A (VERY rough) measure of ‘sentience’ tho is ‘what kind of stories can we tell about what it’s like to be a particular thing’. The ‘story’ of a photon, or even a rock, is going to be much simpler than the same thing for a bacterium or a human. (It’s not obvious tho that we might ‘miss’ some, or even most, ‘sentience’ because it’s so alien to our own experiences and understanding.)
I don’t think ‘consciousness’ can exist without ‘temporal memory’ and ‘language’ (i.e. an ability to communicate, even if only with oneself).
So, along these lines, non-human primates/apes probably are somewhat conscious. They can tell ‘lies’ for one. Evidence for their consciousness being more limited than our own is that the ‘stories they tell’ are much simpler than ours.
But I think one nice feature of these ideas is that it seems like we could in fact discern some facts about this for particular entities (via ‘external observation’), e.g. test whether they do have ‘temporal memory’ or language (both evidence of ‘consciousness’) or whether they have ‘experiences’ and respond to features of their environment (which would be evidence of ‘sentience’).
I’m with you on information being key to all of this.

We’re using words differently. When I say “consciousness”, I mean “there being something which it is like to be a thing”, which I think you mean by “sentience.” What I would call the thing you call “consciousness” is either “sapience” or “sophonce”, depending on whether you consider self-awareness and agency an important part of the definition (sophonce) or not (sapience). The difference is that I expect tool / non-agentive AGIs to be sapient (in that they can think abstractly), but not sophont (they are not “people” who have an identity and will of their own).
“There being something which it is like to be this thing” is a characteristic I consider likely to be possessed by all systems which are “processing information” in some way, though I am unsure exactly what that means. It certainly seems to be something all living things possess, and possibly some nonliving ones—for instance, it has recently been demonstrated that neural networks can be simulated using the acoustics of a vibrating metal sheet (I read about it in Quanta, I’ll give you a link if you want but it shouldn’t be hard to find), meaning that for the duration that they are being used this way, they (or rather, the algorithm they are running) are as conscious as the network being simulated would be.
I think that photons do not have this characteristic—they are not sentient in your terms—because they aren’t interacting with anything or doing anything as they float through the aether. Possibly sparks of qualia exist when they interact with matter? But I don’t know the physical details of such interactions or whether it is possible for a photon to remain “the same photon” after interacting with other matter—I expect that it is a meaningless concept—so there would be no continuity of consciousness / sentience whatsoever there—nothing remotely resembling a being that is having the experience.
A rock on the other hand maybe would have a rather continuous experience, albeit unimaginable to us and extremely simple, due to the coherence of its physical form and the fact that acoustic vibrations (which maybe are a kind of computation or information processing, in a sense?) are traversing it. But if information processing means something more than that, then rocks wouldn’t either. I’m really not sure about all that.
Yeah, my current personal definitions/models of ‘consciousness’ and ‘sentience’ might be very idiosyncratic. They’re in flux as of late!
I think photons are more complicated than you think! But I also don’t think their ‘sentience’ is meaningfully different than from a rock. A rock is much bigger tho, and you could tell ‘stories’ of all the parts of which it’s made, and I would expect those to be similar to the ‘stories’ you could tell about a photon; maybe a little more complicated. But they still feel like they have the same ‘aleph number’ in ‘story terms’ somehow.
I think what separates rocks from even viruses, let alone bacteria, is that the ‘stories’ you could tell about a rock are necessarily and qualitatively simpler, i.e. composed of purely ‘local’ stories, or for almost all parts. The rock itself tho is, kinda, in some sense, a memory of its history, e.g. ‘geological weathering’.
It’s hard to know, in principle, whether we might be missing ‘stories’, or sentience/consciousness/qualia, because those stories are much slower than ours (or maybe much faster too).
Viruses, bacteria, and even probably the simplest possible ‘life prototypes’ all seem like they’re, fundamentally, ‘just’ a kind of memory, i.e. history.
‘Rocks’ have stories composed of statis, simple fixed reactions, and maybe sometimes kinds of ‘nested explosions’ (e.g. being broken apart into many pieces).
‘Life’ has a history – it IS a history, copying itself into the future. It’s on ‘another level’ (‘of ontology’? of ‘our ontology’?) because it’s the kid of thing capable of ‘universal computation’ based on molecular dynamics.
We’re a kind of life capable of cognitive (and cultural) ‘universal computation’ – there might be a LOT of this kind of life beyond our own species; maybe most things with something like a brain or even just a nervous system? Humans do seem ‘programmable’ in a way that almost everything else seems ‘hard-coded’. Some other animals do seem to have some limited programmability; maybe not ‘universal programmability’ tho?
I think we (humans) are, or many of us anyways, ‘universally programmable’ via, e.g. culture, or (‘conscious’) ‘reasoning’.
A definition of ‘sentient’:
‘Perceive’ seems relatively ‘sharp’ for us; and this site generally. (Do you disagree?)
‘Feel’ I think could be helpfully sharpened to ‘can react to specific things’. I think it’s sensible to think that we can ‘feel’ things that we’re not consciously aware of. (We probably can’t consciously report those feelings tho! Or not easily.)
Tho maybe ‘feel’ reasonably requires ‘consciousness’, i.e. the ability to tell a story about feelings, i.e. tell a story about our internal subjective experience.
I think it makes sense for us to tell a story about a, e.g. lion, being ‘scared’ or ‘afraid’ while being attacked by a pack of wild dogs. I’m less sure that it makes sense to think that the lion itself ‘feels’ those emotions? What do we, what could we, mean by that?
I don’t think there’s any evidence that lions can themselves ‘tell a story’ that mentions that fear. I wouldn’t guess that there’s anything going on in the lion’s brain/mind that’s at all like telling itself “Oh shit oh shit oh shit”. I don’t think there’s anything remembering the fear, and its context, or any of the relevant associations. I don’t think it’s just that we can’t know whether the lion ‘feels’, from ‘the outside’, because the lion can’t communicate with us. I don’t think the lion can communicate the fact of its specific fear to other lions either. Nor do I think it can ‘tell itself’ of that specific fear.
It ‘feels’ the fear, but afterwards that fear is ‘gone’. (The effects of that fear can of course persist, even in its brain/mind. But there’s no ‘pointer’ to or memory of that specific fear anywhere in particular.)
I think consciousness is basically ‘being able to tell a story’ and it’s just a kind of ‘convergent inevitability’ that we should generally expect consciousness to also entail/imply ‘being able to tell a story about itself’, and thus also ‘know of itself as a thing in the World’.
The historical connection between “qualia” and the p-zombie thought experiment is extremely unfortunate IMO. We did not need a new term for experience, especially when we already had “phenomenon”.
Agreed
