  • Are words more than their symbols?
    I get subtle movements, which could be described as shivers as you say. Is this what they mean by thinking in words or an inner monologue, where neither the act of speaking nor any actual words are involved?NOS4A2

    It's what they mean by "sub-vocalisation", at least.

    There is nothing occurring that I could call a voice.NOS4A2

    Why not, if it resembles speech in respect of its graph of intensity against time?

    Only some people have it.frank

    I think they are either confused by the unwarranted emphasis on sub-monologue to the exclusion of sub-dialogue (far more typical I expect) or they are reacting consciously or otherwise against the unwarranted inference to actual internal speech.
  • Are words more than their symbols?
    Don't you have brain shivers that appear to rehearse likely conversations with other speakers?

    I mean, don't you find your brain rehearsing the kinds of shivering by which it might recognise and respond effectively to other speakers' likely comments about views you hold? Shivers that tend to proceed with time-intensity envelopes fairly analogous to word-sounds?

    So, I mean, monologues aside, don't you even have quote internal dialogues unquote? (Not actual ones, agreed. Probably.)
  • How Do You Personally Learn?

    As those cats would no doubt advise: the best possible method of learning is play, but at the same time it's crucial that newly acquired knowledge be consolidated through sleep.
  • Poll: Evolution of consciousness by natural selection
    Do you believe that billiard balls experience impacts in the same sense that football players experience impacts?petrichor

    In the more mundane of the two senses which you are right to separate, yes. (The sense of "undergo".) Balls and players both.

    Are you sure that sense is irrelevant? Couldn't it be the ground of your incredulity here?

    I can't imagine how, if there is actually no experience, there could be a situation where it nevertheless seems that there is an experience.petrichor

  • Poll: Evolution of consciousness by natural selection
    I have a hard time with eliminativism or illusionism. I can't imagine how, if there is actually no experience, there could be a situation where it nevertheless seems that there is an experience.petrichor

    Experience is undeniable, yes. But unconscious billiard balls can experience impacts, and unconscious computers can experience changes in state or configuration, analogous to our messier brain shivers.

    What is deniable is that a shiver experienced by the brain is ever actually accompanied by a corresponding picture in the brain, or world in the brain.
  • Could we be living in a simulation?
    More generally, there is a literal world of difference between a matrix world in which real humans are immersed in a digital world that they believe is real, and a simulated world with simulated humans -unenlightened

    Then again, it's conceivable that simulated humans could be real AI's, immersed in a virtual digital world. Conceivably, they might be fooled.

    (Though, more realistically, they would probably need to interact with a real environment in order to develop a proper semantics, and be fooled about anything, in what we ought recognise as a conscious, and hence relevant, way.)

    I do agree that a literal world of difference remains, though, between that conceivable scenario, and simulation hypothesising (Bostrom et al), in which fictional worlds with fictional humans magically become real.

    There can be no escape from the simulation for simulated persons, if such are possible, and since for them it is their only world, for them it is reality, and the programmer is God.unenlightened

  • Reading "The Laws of Form", by George Spencer-Brown.
    (you don't have to agree, I'm just giving shape to the way the axioms work with a familiar example.)unenlightened

    I get a different shape? More like, axiom 1 is about saying a thing (e.g. "Romeo!")... which, if you do it again, is only to reinforce that first statement (or state-naming!).

    While, axiom 2 is about changing sides on the issue ("rather, thou art some other, that smell as sweet")... which, if you do it again, is only to undo that first change. And probably end up where it started.

    Assertion and negation, basically?

    A semantic grammar is a semantic syntax. So not necessarily a true semantics. Not necessarily joining in the elaborate social game of relating maps to territories. Not necessarily understanding. Possibly becoming merely (albeit amazingly) skilled in relating maps to other maps.
  • Is indirect realism self undermining?
    whether or not we should describe perception as "seeing representations" or "seeing the external world stimulus" is an irrelevant issue of semantics. It's like arguing over whether we feel pain or feel the fire.Michael

    So it's a crucial issue of semantics. Should the psychology admit internal representations, as well as external representations and internal brain shivers?
  • Is indirect realism self undermining?
    Yes. The broken leg is the trauma. The brain activity (or the mental phenomena it causes) is the pain.Michael

    Ok. The broken leg is trauma. The brain activity (the recognising the broken leg as an instance of trauma) is the feeling pain.

    And yet as I said we can recognise trauma without "feeling pain" (e.g. congenital insensitivity to pain)Michael

    Sure. The associations effected by merely intellectual recognition of the trauma hardly overlap at all with the associations we are inclined to call "feeling pain", which are informed directly by stimulation of nerves in the site of the trauma.

    and we can feel pain without recognising trauma (e.g. headaches).Michael

    Sure. We can recognise wrongly.
  • Is indirect realism self undermining?
    Hmm so you were distinguishing neural alarm from bodily trauma?
  • Is indirect realism self undermining?
    We don’t just associate pain with trauma; we feel pain in response to trauma. They are two separate things.Michael

    I'm suggesting the pain is the recognition of the trauma as an instance of a kind of thing, e.g. of trauma. It is the association. Sure it's separate from the trauma. It might be caused by the trauma. But not from or by the pain. It is the pain.
  • Is indirect realism self undermining?
    I don’t need a language to be in pain. Pre-linguistic humans had headaches.Michael

    They suffered the trauma. My car suffers trauma. And pain, but only metaphorically. They, though, probably also had enough symbolic ability to associate it with trauma in general. Which is how we suffer pain literally. Perhaps. Plausibly.
  • Is indirect realism self undermining?
    Sure. I'm not totally averse to saying that mental phenomena just is brain activity. What I'm averse to is the claim that being in pain has something to do with me saying "I am in pain"Michael

    But then, applying that to the snooker balls, you're averse to saying that seeing the ball as red has something to do with associating it with red surfaces generally? For example by reaching for the word "red". I thought you might be. Slightly surprised that you reply with "sure".

    If you're not totally averse to that, though, how about that being in pain is associating the bodily trauma in question with bodily trauma in general? For example by reaching for the word "pain".
  • Is indirect realism self undermining?
    would that be tantamount to accepting that gravity is mystical?frank

    There's mystical and there's mystical. There's an invisible pull between two bodies proportional to their masses, and there's a picture show in the head.

    As for SDR, I'm not at all sure I'm on side with any brand of realism, inasmuch as they mostly seem to discuss the possibility of some kind of inner ghost making contact with the outer world.
  • Is indirect realism self undermining?
    You don't have to think of experience as a collection of ghosts, though. You can just note that you do see red, and leave it unexplained exactly how.frank

    That seems tantamount to accepting the ghost as ghost? Which could turn out to be appropriate, of course. I'm just pointing out an alternative.
  • Is indirect realism self undermining?
    You put a red ball and a blue ball in front of me. I can see that one is red and one is blue. I don't need to do or say anything that you can interpret as me "seeing red" or "seeing blue".Michael

    But perhaps you need to have brain activity that succeeds in associating the red ball with red surfaces generally, and the blue ball with blue surfaces generally?

    Having red or blue mental images in the brain, to meet that purpose, is kind of having a ghost in the machine.

    Having the brain reach for suitable words or pictures, isn't. And, even better, it suggests a likely origin of our tendency to imagine that we accommodate the ghostly entities.
  • Is indirect realism self undermining?
    read this.Michael

    pdf, anyone?
  • Is indirect realism self undermining?
    Again, you seem to fail to understand the use-mention distinction.

    But this isn't the main point.
    Michael

    Perhaps yes it is, and no we don't fail. We, the people disputing the reality of private experience, understand that seeing colours is using (hence reaching for) words and pictures in order to mention (refer to, and thereby identify, classify, compare and order) visual stimuli.

    This symbolic skill does tend to thrive on casual confusion of symbol and object, such as the kind usefully diagnosed as use-mention, but also (by the way, just saying...) the kind that confuses either symbol or object with brain shiver.

    Without language, your target image might illicit responses that deserved classifying as a nascent form of recognition or comparison or classification of colours. Perhaps an animal would be reminded (as it were) of a face, in response to the whole set of local contrasts. But to imagine that all of the concentric rings would be identified as instances of separate classes of stimuli... That implies language, proper.
  • Exploring the artificially intelligent mind of GPT4
    Searle argues that even though the person in the room can produce responses that appear to be intelligent to someone who does not understand Chinese,Bot to Banno

    Searle's requirement, to the contrary, that the room should convince even Chinese speakers, always seemed somewhat audacious. Until now?

    While the person in the Chinese Room follows a static set of rules to manipulate symbols, GPT-4's neural network is capable of generalization, learning, and adaptation based on the data it has been trained on. This makes GPT-4 more sophisticated and flexible than the static rule-based system in the Chinese Room.Bot to Pierre-Normand

    Did Searle concede that the rules followed were static? If so, was 'static' meant in a sense contradicted by the present (listed) capabilities? I had the impression it would have allowed for enough development and sophistication as to lead exactly to those capabilities, which would be necessary to convince a semantically competent audience. For 'static' read 'statistical'?

    Then GPT-4 is nothing not envisaged in Searle's account.
  • Who Perceives What?

    Does the camera, producing the photo, directly perceive the tree?

    Also.

    Is it different for words? When you see the name "Fido", do you indirectly perceive the dog?

    Or is it more relevant to ask: when you read a description of Fido, do you indirectly perceive the dog?
  • Who Perceives What?


    I'm not sure. I recall @Terrapin Station arguing for that kind of direct realism, and likening the alleged directness of his alleged mental representations awareness to the fidelity commonly attributed to photos over and above hand-drawn painting. If I read him right.

    I'm curious whether the OP's point is the same (boo) or different (hooray).

    can be prevented from arising, at least within discourse referring to the story. You might say that a feature of fantasy as a specific genre is that such a protest can be suppressed indefinitely. The discourse (the variety of things it's helpful to say about the story) can be shielded from normal influences and standards of conduct. Selectively, that is. Shielded from normal standards of evaluating existence claims, but thereby enabled to apply normal standards of inference about certain events in the story.

    But fiction generally, and even fantasy to some extent, seems to have things to say about things outside of it. Consequently, interpretations of sentences, such as your formal paraphrase of a sentence, are likely to be judged with some degree of reference to real-world criteria.

    Then your question, how the fictional sentence should be interpreted, is fair, and I think there are two kinds of answer: half-measure and full-measure.

    Half-measure is some way of relativising the statement to the story. To talk about the fiction-related discourse from outside. E.g. qualify statements by way of disclaimers like "in the story" or "fictionally speaking".

    Full-measure is to seek to reconcile the truth of the fictional statement with that of factual statements. The popular way to do so is to treat the statement as on a par with conditional or hypothetical statements: so that they might paraphrase along the lines of, e.g. "suppose for the sake of argument that there exists an x such that..."; or "consider the set of possible worlds in which there exists an x such that...".

    Less well known is Goodman's approach, in which the story is acknowledged literally false, but allowed to be metaphorically true in a manner that has the novel advantage of being about the real world.

  • Why is the Hard Problem of Consciousness so hard?
    for example, we experience visual sensations: the felt quality of redness,Nagel/Chalmers

    We prepare to point appropriate symbols at the stimulus: pictures of just the right shade, words selecting the right pictures. And we prepare to point other symbols at the biological activity that we infer effects the process of preparation. We find it useful, and generally harmless, to equivocate (in talk and in thought) between word, picture, stimulus, associated stimuli, and neural process. Unsurprisingly we often have to unpick an apparently reliable (because habitual) account alleging that a picture glows, somewhere inside our head.

    the experience of dark and light,Nagel/Chalmers

    The need to prepare to select pictures having the right luminosity when illuminated, so as to associate the stimulus with an appropriate range of stimuli, and of words and of objects.

    the quality of depth in a visual field.Nagel/Chalmers

    Pictures satisfying learnt pictorial conventions of perspective.

    Other experiences go along with perception in different modalities: the sound of a clarinet,Nagel/Chalmers

    Not another experience in the sense of another wonderful ghostly correlate of neural activity, but another (wonderful) physical process of readying to select among sounds to associate with the presented sound, thereby contributing to an ongoing classification and ordering of the world of sound events. A process soaked in the same multiple confusion of use with mention: reference to stimulus with reference to symbol; symbol with neural readying for use of symbol; stimulus with neural readying for use of symbol.

    the smell of mothballs.Nagel/Chalmers

    Where the associations may be especially deep and cross-modally disruptive.

    Then there are bodily sensations, from pains to orgasms;Nagel/Chalmers

    There is physiological trauma and convulsions, and there is interpretation of these through language and other symbol systems. And with the interpretation, endemic intellectual confusion, and habitual implication of an internal observer.

    mental images that are conjured up internally;Nagel/Chalmers

    In a manner of speaking, which benefits from translation into literal analysis, in terms of preparation to manipulate and interpret diagrams and visual talk.

    the felt quality of emotionNagel/Chalmers

    The physiological turbulence, and then the interpreting it through language and other symbol systems, especially (and usefully and often truly) with respect to social and physical threats and opportunities.

    and the experience of a stream of conscious thought.Nagel/Chalmers

    The tendency to confuse the continuity of actual scenery with the continuity of an internal picture show.

    what unites all of these states is that there is something it is like to be in them.Nagel/Chalmers

    There is a topography of more and less appropriate linguistic (and otherwise symbolic) interpretations and reactions to the situation in which the organism finds itself.

    All of them are states of experience.Nagel/Chalmers

    But not of a ghost in the machine.
  • The "self" under materialism
    On the surface level, if we have a "self" in the materialist worldview, we inevitably run into the "Ship of Theseus" problem.tom111

    Yes, and I don't see any deeper issue.

    So why is it, when I look back at photos of myself from 5 years ago, I feel like the same person?tom111

    Well, why is it that when you look back at photos of your ship from 5 years ago, you feel like it's the same ship?

    This is likely due to the fact that you have inherited memories from this person,tom111

    And likewise you have memories of the earlier ship.

    What we are (in the materialist view) are simply piles of carbon,tom111

    Or living flesh, why not? Does a materialist have to be exclusively a physical chemist?

    using past memories and ideas to compile a constant "self" that simply doesn't exist;tom111

    Agreed, if self is soul. But why can't it be the animal?

    a human being is empty of essence.tom111

    Agreed.

    Upon thorough examination, the idea of a "self" is as arbitrary as the idea of a "chair", or any other object.tom111

    Wobbly, sure, with no solid foundation. But not entirely arbitrary, surely? You have the vehicle's service history?

    In a purely material world, concepts like these simply don't exist worktom111
