Literally just mainlining marketing material straight into whatever’s left of their rotting brains.
so i know a lot of other users will just be dismissive but i like to hone my critical thinking skills, and most people are completely unfamiliar with these advanced concepts, so here’s my philosophical examination of the issue.
the thing is, we don’t even know how to prove HUMANS are sentient except by self-reports of our internal subjective experiences.
so sentience/consciousness as i discuss it here refers primarily to Qualia, or to a being existing in such a state as to experience Qualia. Qualia are the internal, subjective, mental experiences of external, physical phenomena.
here’s the task of people that want to prove that the human brain is a meat computer: Explain, in exact detail, how (i.e. the procsses by which) Qualia, (i.e. internal, subjective, mental experiences) arise from external, objective, physical phenomena.
hint: you can’t. the move by physicalist philosophy is simply to deny the existence of qualia, consciousness, and subjective experience altogether as ‘illusory’ - but illusory to what? an illusion necessarily has an audience, something it is fooling or decieving. this ‘something’ would be the ‘consciousness’ or ‘sentience’ or to put it in your oh so smug terms the ‘soul’ that non-physicalist philosophy might posit. this move by physicalists is therefore syntactically absurd and merely moves the goalpost from ‘what are qualia’ to ‘what are those illusory, deceitful qualia decieving’. consciousness/sentience/qualia are distinctly not information processing phenomena, they are entirely superfluous to information processing tasks. sentience/consciousness/Qualia is/are not the information processing, but internal, subjective, mental awareness and experience of some of these information processing tasks.
Consider information processing, and the kinds of information processing that our brains/minds are capable of.
What about information processing requires an internal, subjective, mental experience? Nothing at all. An information processing system could hypothetically manage all of the tasks of a human’s normal activities (moving, eating, speaking, planning, etc.) flawlessly, without having such an internal, subjective, mental experience. (this hypothetical kind of person with no internal experiences is where the term ‘philosophical zombie’ comes from) There is no reason to assume that an information processing system that contains information about itself would have to be ‘aware’ of this information in a conscious sense of having an internal, subjective, mental experience of the information, like how a calculator or computer is assumed to perform information processing without any internal subjective mental experiences of its own (independently of the human operators).
and yet, humans (and likely other kinds of life) do have these strange internal subjective mental phenomena anyway.
our science has yet to figure out how or why this is, and the usual neuroscience task of merely correlating internal experiences to external brain activity measurements will fundamentally and definitionally never be able to prove causation, even hypothetically.
so the options we are left with in terms of conclusions to draw are:
- all matter contains some kind of (inhuman) sentience, including computers, that can sometimes coalesce into human-like sentience when in certain configurations (animism)
- nothing is truly sentient whatsoever and our self reports otherwise are to be ignored and disregarded (self-denying mechanistic physicalist zen nihilism)
- there is something special or unique or not entirely understood about biological life (at least human life if not all life with a central nervous system) that produces sentience/consciousness/Qualia (‘soul’-ism as you might put it, but no ‘soul’ is required for this conclusion, it could just as easily be termed ‘mystery-ism’ or ‘unknown-ism’)
And personally the only option i have any disdain for is number 2, as i cannot bring myself to deny the very thing i am constantly and completely immersed inside of/identical with.

Why not? I understand that we cannot, at this particular moment, explain every step of the process and how every cause translates to an effect until you have consciousness, but we can point at the results of observation and study and less complex systems we understand the workings of better and say that it’s most likely that the human brain functions in the same way, and these processes produce Qualia.
It’s not absolute proof, but there’s nothing wrong with just saying that from what we understand, this is the most likely explanation.
Unless I’m misunderstanding what you’re saying here, why is the idea that it can’t be done the takeaway rather than it will take a long time for us to be able to say whether or not it’s possible?
and the usual neuroscience task of merely correlating internal experiences to external brain activity measurements will fundamentally and definitionally never be able to prove causation, even hypothetically.
Once you believe you understand exactly what external brain activity leads to particular internal experiences, you could surely prove it experimentally by building a system where you can induce that activity and seeing if the system can report back the expected experience (though this might not be possible to do ethically).
As a final point, surely your own argument above about an illusion requiring an observer rules out concluding anything along the lines of point 2?
Why not?
because qualia are fundamentally a subjective phenomena, and there is no concievable way to arrive at subjective phenomena via objective physical quantitites/measurements.

this is not true. for example, take the example of a radio, presented to uncontacted people who do not know what a radio is. It would be reasonable for these people to assume that the voices coming from the radio are produced in their entirety inside the radio box/chassis, after all, when you interfere with the internals of the radio, it effects which voices come out and in what quality. and yet, because of a fundamental lack of understanding of the mechanics of the radio, and a lack of knowledge of how radios are used and how radio programs are produced and performed, this is an entirely incorrect assessment of the situation.
in this metaphor, the ‘radio’ is analogous to the ‘brain’ or ‘body’, and the ‘voices’ or radio programs are the ‘consciousness’, that is assumed to be coming form inside the box, but is in fact coming from outside the box, from completely invisible waves in the air. the ‘uncontacted people’ are modern scientists trying to understand that which is unknown to humanity.
this isn’t to say that i think the brain is a radio, although that is a fun thought experiment, but to demonstrate why correlation does not, in fact, necessarily imply causation, especially in the case of the neural correlates of consciousness. consciousness definitely impinges upon or depends upon the physical brain, it is in some sense affected by it, no one would argue this point seriously, but to assume causal relationship is intellectually lazy.
because qualia are fundamentally a subjective phenomena, and there is no concievable way to arrive at subjective phenomena via objective physical quantitites/measurements.
Having done some quick reading, I can see that qualia are definitionally subjective, but I would question how anyone could assert that they possess internal mental experiences that “no amount of purely physical information includes.”, or that such a thing can even exist with any level of confidence. Certainly not enough confidence to structure an argument around. The justification seems to be the idea that because we cannot do something now, that thing cannot be done. I don’t find that convincing.
This might be going too far into the analogy, but I think the problem with a comparison to a radio is that if you examine the radio down to its smallest part, and then assemble a second radio, that radio will behave in the same as the first.
Presumably as well, with enough examination, it would come to be understood that the voices coming from the radio are produced somewhere else, and there would be no reason for anyone to think that the voices themselves are appearing from an intangible and inherently subjective origin. If consciousness is essentially a puppeteer for the physical human body, that doesn’t preclude consciousness existing physically somewhere else, and that the “broadcaster” isn’t something capable of examination or imitation.
The whole argument seems to boil down to “maybe consciousness doesn’t work the way science would currently suggest it does.” but doesn’t present any evidence that the consciousness is somehow unsolvable.
but to assume causal relationship is intellectually lazy.
Instead, assuming that an undetectable intangible and fundamentally improvable mechanism is behind consciousness without proof is worse than lazy, it’s magical thinking. While I don’t think you could ever prove that that wasn’t the case, it should only seriously be entertained once every other option has been thoroughly exhausted.
(Reading this back, this feels quite confrontational. I don’t intend it to be, but I lack the ability to word it in the tone that I would prefer.)
If what you’re saying is true for human consciousness though, then it means that there are other undiscovered factors (invisible non EM airwaves, astrology, aliens etc) which influence our mood and state of being. Which I’m not even arguing against, but it would be a revolution in science
there is something special or unique or not entirely understood about biological life (at least human life if not all life with a central nervous system) that produces sentience/consciousness/Qualia (‘soul’-ism as you might put it, but no ‘soul’ is required for this conclusion, it could just as easily be termed ‘mystery-ism’ or ‘unknown-ism’)
This is just wrong lol, there’s nothing magical about vertebrates in comparison to unicellular organisms. Maybe the depth of our emotions might be bigger, but obviously a paramecium also feels fear and happiness and anticipation, because these are necessary for it to eat and reproduce, it wouldn’t do these things if they didn’t feel good
The discrete dividing line is life and non-life (don’t @ me about viruses)
central nervous systems are so far the only thing we almost universally recognize as producing human-like subjectivity (as our evidence is the self report of humans), so i restricted my argumentation to those parameters. for all i know every quark has a kind of subjectivity associated with it, it could be as fundamental to reality as matter. and for all i know a paramecium responds to its environment with purely unconscious instinct (or if that terminology is inaccurate, biological information processing) without an internal experience. we don’t really understand how subjectivity is produced well enough to isolate it for empirical study in humans, let alone mammals, let alone microbes - but i personally think it is plausible that all life if not all matter has some kind of subjectivity.
and for all i know a paramecium responds to its environment with purely unconscious instinct (or if that terminology is inaccurate, biological information processing) without an internal experience
unicellular organisms have been shown to learn. It’s literally the same thing as a vertebrate, just less complex
I don’t find that obvious at all. I agree there is nothing special dividing vertebrates from unicellular organisms, but I definitely think that some kind of CNS is required for the experience of emotions like fear, happiness etc. I do not see at all how paramecium could experience something like that. What part of it would experience it? Emotions in humans seem to be characterised by particular patterns of brain activity and concentrations of certain molecules (hormones, etc). I really cannot see how a unicellular organism has any capacity to experience emotions as we do. I would also argue that there is no dividing line between life and non-life. Whether something is alive or not is quite nebulous and hard to define. As you say, viruses are a good example but there are many others. Eg. a pregnant mammal. The foetus does not fill the classical, basic conditions of life that are taught in school (MRS H GREN, or whatever acronym) but does it really make sense to say that it is not alive? How many organisms are there when we look at a pregnant mammal. It is not clear.
but I definitely think that some kind of CNS is required for the experience of emotions like fear, happiness etc.
okay, so when a scallop runs away from you it doesn’t feel fear?
and when a paramecium is being ensnared by a hydra or some weird protist on your microscope slide, and it’s struggling to get away, it doesn’t feel fear? lol
Obviously every moving living thing can feel fear, that’s why they’re moving living things and that’s why they run away from predators
I would also argue that there is no dividing line between life and non-life. Whether something is alive or not is quite nebulous and hard to define
With a few exceptions like viruses, it’s pretty obvious. Rocks don’t make more rocks, nor does water
It seems by your periodically hostile comments (“oh so smug terms the ‘soul’”) indicates that you have a disdain for my position, so I assume you think my position is your option 2, but I don’t ignore self-reports of sentience. I’m closer to option 1, I see it as plausible that a sufficiently general algorithm could have the same level of sentience as humans.
The third position strikes me as at least just as ridiculous as the second. Of course we don’t totally understand biological life, but just saying there’s something “special” is wild. We’re a configuration of non-sentient parts that produce sentience. Computers are also a configuration of non-sentient parts. To claim that there’s no configuration of silicon that could arrive at sentience but that there is a configuration of carbon that could arrive at sentience is imbuing carbon with some properties that seems vastly more complex than the physical reality of carbon would allow.
i think it is plausible to replicate consciousness artificially with machines, and even more plausible to replicate every information processing task in a human brain, but i do not think that purely information processing machines like computers or machines using purely information processing tools like algorithms will be the necessary hardware or software to produce artificial subjectivity.
by ‘special’ i meant not understood. and again, i submit not that it is impossible to make a subjectivity producing object like a brain artificially out of whatever material, but that it is not possible to do so using information processing technologies and theory (as understood in 2023). I don’t think artificial subjectivity is impossible, but i think purely algorithmic artificial subjectivity is impossible. I don’t think that a purely physicalist worldview of a type that discounts the possibility of subjectivity can ever account for subjectivity. i don’t think that subjectivity is explainable in terms of information processing.
here’s a syllogism to sum up my position (i believe i have argued these points sufficiently elsewhere in the thread)
Premise A: Qualia (subjective experiences) exist (a fact supported by many neuroscientists as per one of my previous posts wikipedia quote)
Premise B: Qualia, as subjective experiences, are fundamentally irreducible to information processing. (look up the hard problem of consciousness and the philosophical zombie thought experiment)
Premise C: therefore consciousness, which contains (or is identified with or consists of or interacts with or is otherwise related to) Qualia, is irreducible to information processing.
Premise D: therefore the most simplistic of physicalist worldviews (those that deny the existence of Qualia and the concept of subjectivity, like that of Daniel Dennett) can never fully account for consciousness.
thats it, nothing else i’m trying to say other than that. no mysticism, no woo, no soul, no god, no fairies, nothing to offend your delicate aesthetic sensibilities. just stuff we don’t know yet about the brain/mind/universe. no assumptions, just an acknowledgement that we do not have a Unified Theory of Everything and are likely several fundamental paradigm shifts in thinking away in many fields of research from anything resembling one.
Premise B is where you lost me.
The premise of philosophical zombies is that it’s possible for there to be beings with the same information processing capabilities as us without experience. That is, given the same tools and platforms, they would be having just as intricate discussions about the nature of experience and sentience. without having experience or sentience.
I’m not convinced it’s functionally possible to behave the way we behave when talking & describing sentience without being sentient. I think a being that is functionally identical to me except that it lacks experience wouldn’t be functionally identical to me, because I wouldn’t be interested in sentience if I didn’t have it.
Little late to the thread but really enjoying your posts. Curious on your thoughts if you don’t mind:
As a philosophy newbie myself, could it be a lot of this discussion/debate is due to people having no exposure to the metaphysical concepts of objectivity/subjectivity? It seems a bit portion of your argument is that people who believe we can achieve ai sentience are already committed to a (leap of faith) absolute belief in the “physicalist” model/understanding of the universe?
Also regarding the idea of a “Unified Theory of Everything”, do you believe in this as a possibility? Is having that as a goal or destination in of itself a representation of a particularly misguided “physicalist” way of thinking that many people are already committed to/trapped within?
