    We can use our models and shared language to report the state of our models and shared language. Saying "Ah, but your conclusion is just a model too" isn't sufficient on its own to undermine anything.Isaac

    Our models and shared language include private and subjective. The mental talk is part of ordinary language. What's ironic here is that ordinary language philosophy in the form of a certain interpretation of Wittgenstein is being used to discount the ordinary talk of mental states.

    Can computers describe their own calculations in detail, bit by bit? Or do they only report the results of theses calculations, at points specified in the program? It makes a difference.Olivier5

    I don't see what that's got do do with the metaphor. All I'm saying is that computers can use their internal calculation mechanisms to report the state of that same mechanism.

    To a degree. The only thing I'd say is that I don't consider the 'thing in itself' to be beyond our reach. I think a model is us reaching it. There's no more 'it-ness' than the impact on our models. Not like there's a 'really real' tree out there and all we have is approximations to it. Out approximations are the tree, the 'really real' one, the hidden states that cause us to model a 'tree' are revealed to us by our sense organs as they 'really' are. We might not be able to sense all there is to be potentially sensed, but that doesn't make what we do sense less real.

    I'm not arguing that mental states aren't real, only that they're socially constructed (to the extent that I'm arguing, anyway).

    — Luke

    No you don't. You think and wonder using neurons. You talk using language.
    Isaac

    Well, it seems to me like I think and wonder in language, if that's any different. I'm never aware of myself thinking and wondering using neurons.

    what I'm consciously aware of does not have the nature of, or is not in the form of, a brain signal
    — Luke

    It obviously does.
    Isaac

    How is it obvious? I know what I'm consciously aware of and it isn't brain signals. And neither is it in the form of brain signals.

    But you seem to be missing the point I raised a few posts back (Shakespeare/Milton example). Common use of 'about', or 'of' when it comes to awareness assumes one can be wrong in identifying the object.Isaac

    I think there are two different meanings of "awareness" at work here, and both are "common use". You want to restrict "awareness" to mean (only) "knowledge", such as with your Shakespeare example. Although I do find the question "Are you aware of the works of Shakespeare?" somewhat odd. It seems more natural to ask "Do you know the works of Shakespeare?" Nevertheless...

    On the other hand, I'm using "awareness" to mean "present to mind" or simply "conscious (of)". I don't believe this is an uncommon usage. Merriam-Webster defines "conscious" as "perceiving, apprehending, or noticing with a degree of controlled thought or observation". The Wikipedia article on Awareness opens with: "Awareness is the state of being conscious of something."

    Yet here you want to say that whatever you think is the object of your awareness just is, purely by virtue of the fact that you think it is. That seems contrary to the way we use the expression in all other areas.Isaac

    In terms of conscious awareness, the fact of the matter is whatever is present to one's mind or whatever one is conscious of, including one's own sensations/feelings/perceptions. It needn't be public knowledge nor amenable to public correction.

    But I said "...because they're connected to the part of your brain for which activity therein is what we call 'conscious awareness'". That's how.Isaac

    All you have done here is to identify brain activity with conscious awareness; it doesn't explain how you are conscious of your brain activity. As I said earlier: "The awareness of my arm movements might be the result of my brain function, but that doesn't mean I have awareness of my brain function".

    The process by which you become aware is as described, but it is absolutely evident that it is not 'your arm' that you become aware of.
    — Isaac

    Then what is it that you are aware of?
    — Luke

    We could say neural signals, or we could perhaps also talk about models, or features of perception to get away from neuroscience terms.
    Isaac

    Since you didn't actually apply any of this to your arm example, I don't see how it helps. Clearly, the person is aware of - that is, conscious of - their arm being in a particular location, even though their arm isn't in that location. Otherwise, what did you mean by the italicised part of "you think your arm is doing one thing, but it's actually doing another"?

    Well, it seems to me like I think and wonder in language, if that's any different. I'm never aware of myself thinking and wondering using neurons.Luke

    No, I don't suppose you would be. I don't suppose you're aware of your kidney's functioning either, but that doesn't mean they don't. again, what you have to take on board (if you agree with the science of course - it is speculative after all), is that what you think is happening is a post hoc narrative put together after the actual event. Let's take a really simple example - turning a light switch on. When you switch the switch you no doubt think that you switched the switch, then you saw the light come on. You didn't. You saw the light come on before you felt you'd switched the switch. The signals from your finger took longer to get to your brain than the light took. Your occipital cortex processed the data from the light bulb before it even received the data from your finger. It sent signals to the parts of your brain dealing with object recognition and spatiotemporal response, all before the signal from your finger had even arrived. These even reached the same areas of your brain usually involved in conscious processing...then the data from your finger arrived. this new data was sent to the part of your brain dealing with sequencing (episodic memory). It then sent backward acting neural signals which suppressed sequencing data in the original message coming from the occipital cortex. It changed the story to make it seem like you saw the light after you switched the switch, because that's what you were expecting to see (based on what you know about switches and lights, cause and effect).

    So what actually happens in areas we know deal with specific sub-parts of processing the stream of conscious awareness is not what you later recall happened. If we artificially interrupt this sequence we can get you to think the initial sequence is what happened. It did enter your conscious steam of thought, you just revised it a few milliseconds later. Your introspection does provide you with an accurate picture even of your stream of conscious awareness. It provides you with a heavily filtered, selective and occasionally flat out made-up narrative of what just happened. Most of that re-telling of the story is affected by models picked up in childhood - ie culturally mediated, public data.

    It seems you think in language because you've been enculturated into modelling your thoughts that way. Whatever goes on in your brain, you're going to post hoc re-tell the narrative to fit the model you're expecting it to fit, in this case "all my thoughts were words". It may or may not work with you, but one introspective exercise that sometimes is revealing is to work out some relatively complex strategy - say how you're going to negotiate an obstacle course, or solve a bit of first order logic. Then try to recall (if you really think in words) the exact sentences you used to think that through, word-for-word. Most people can't.

    You think too fast to form full sentences, but we're so embedded in language that the language centres of our brains convert the stuff we think into words as we go assuming we might need to communicate it at any moment. Since the thoughts are too fast, it only has time to select a few key words - hence the incomplete sentences. Your brain (if it has been enculturated to do so) interprets this association as 'thinking in words' and so it suppresses the data with the alternate sequencing because it's not expecting it. You end up with the narrative that you thought in words.

    I think there are two different meanings of "awareness" at work here, and both are "common use".Luke

    Yes. I've not made clear what I was trying to do there. I'm not disputing that your use is common. What I was trying to highlight is the (what I believe is unjustified) special pleading with which 'awareness' os used differently with regards to the mind than in all other cases. I don't dispute it's common use, I dispute it's revealing anything useful about the way the mind works. It's a comforter, not an insight.

    All you have done here is to identify brain activity with conscious awareness; it doesn't explain how you are conscious of your brain activity.Luke

    This is another way in which mind-talk uses 'special pleading'. If you ask me how the petrol gets to the engine in a car, a description of the fuel pump and line is usually considered to have answered the question 'how?'. Maybe a description of pressure in a closed space might be added if necessary. Whenever minds are introduced, suddenly any description of process has no longer answered the question 'how?'. it's like one can forever ask - "but how does all that lead to conscious awareness?" and absolutely anything said will be unsatisfactory. What would an answer look like, to you. Give me an example answer to the question "how are you conscious of your brain activity?" that you would accept as a satisfactory series of steps.

    We can stipulate in the code (or add in some parallel code) one or several reporting routines that regularly outputs a certain data set, following certain milestones. So the CPU can be monitored through regular reporting of some data set eg 10 times per second, but one cannot access the actual electric currents inside the CPU that produce these data sets, as they happen. Of course one could hypothetically reconstruct them by parsing together the reported data, but not empirically record the physical events in the CPU. At least not in your random PC. Whether the technology exists in the lab, I am not aware of it.

    To my mind this is important because I actually find useful the computer metaphor for the human mind. Not that people are just computers but they are also computers. We human beings can compute, in fact we invented computing in a way, and then taught it to machines.

    So what does this mean for the mind-body problem? Maybe that our consciousness cannot access the physical, neuronal processes underlying it; it can only access periodic reports from such neuronal processes. Eg visual, audio or pain reports.

    — Olivier5

    Isaac

    Well, glad that's clarified.

    Come to think of it, the original metaphor was made here:

    It always baffles me that this this is seen as some coup de grace. "But the study of social constructs is itself just a social construct", "You're using rationality to work out the origin of rationality", "All metaphysics is nonsense is itself metaphysics"...

    It's just not the logical flaw people seem to assume it is. I can ask a computer to print out the actual binary of its last calculation. There's no problem at all ... Psychology's models of how the brain works (including that we model the world) is itself just a model of the world (in this case the brain bit of it). So what? What's the killer blow we must now succumb to because of that insight?
    Isaac

    The killer blow is that: IF the study of social constructs concludes that social constructs are possible, reasonable, useful and improvable (the Collingwood project if I understand well), then there is no problem, but IF one concludes from the study of social constructs that they are on the whole unreasonable fancies, then one has a problem of self-contradiction. Because the study of social constructs is itself a social construct, and if social constructs are fancy, the idea that they are fancy is itself fancy.

    Likewise, "all metaphysics is nonsense" is reflexive, and thus it is a self-contradictory statement. You will have recognized the paradox of the liar. We already spoke about it.

    And therefore... If models of how the brain works are in themselves just mental models (or social constructs), a model of how the brain works that concludes that mental models and/or social constructs are illusionary, fanciful or epiphenomenal is contradicting itself. Only neurological models that recognise (or better, explain) the utility of conscious human thoughts and social constructs can be asserted without running into internal contradictions.

    This is like saying humans can't fly. Sure, they can't without any mechanical help, but they can with mechanical help. Our consciousness can access the underlying physical processes with a little mechanical/electronical help, by observing (a conscious activity) MRI images of our brain.

    One could also say that humans can't communicate without help of ink, paper, computers and air.

    It basically comes down to being a realist or solipsist

    Either there is a causal relationship of your mind with the world or there isn't. If there is then the relationship between cause and effect is information and effects (the state of your mind) carry information about their causes (the state of the world just prior to some mental state like the state of some internet philosophy forum post as you begin to read it).

    Either your internet forum post contains information about one of your prior mental states or it doesn't. If it doesn't then we're not communicating and you are just a figment of my imagination.

    This is the “killer blow” so far missed. It is human reason itself, the ground of everything human, that is intrinsically circular, therefore susceptible to an illusory conclusions. It is the nature of the rational beast, inevitable and irreconcilable, possible only to guard against, but never to eliminate.

    Science as a doctrine sets the ground for trying, but it is always a human that does science, so.....just more potential circularity.

    Mental models for brain workings that determine that mental models are impossible......is contradictory.

    Indeed, but "all metaphysics except this is nonsense" is not, which is more the equivalent we have here.

    We have some really good neurological models. To discard them would require we discard some fairly fundamental models of the physical world and how we interact with it.

    The problem is those models don't match with the models of our own mental processes we developed prior to being able to examine the workings of their physical substrate. So the job is to make a better set.

    It's not about saying things are 'illusions' because they're models. It's about saying things are illusions because they're bad models.

    That is the first option: the attempt to makes sense of social constructs (or mental processes) is potentially useful because social constructs (or mental processes) are sometimes reasonable, useful and improvable. In other words, we are talking of a non-eliminative theory of social constructs (or non-eliminative neurology).
