• First vs Third person: Where's the mystery?
    The problem is, no third person explanation can arrive at first person experience.hypericin
    I guess I didn't see much difference between a description and an explanation. My point was that no anything will arrive at the 'experience' part of it.
    Chalmers' explanation certainly doesn't arrive at first person experience. "A sauce is needed" is no more an explanation than it not being needed.

    And I disagree. First person (the PoV part, not the human qualia associated with 'experience') is trivial. The experience part (qualia and such) is 'what it is like', and that part cannot be known about something else, especially even when it's not even complex. The first person part seems trivial, and entire articles are nevertheless written suggesting otherwise, but seemingly without identifying exactly what's problematic about it.

    The title of this topic is about the first/third person divide, which Chalmers asserts to be fundamental to said 'hard problem', but it isn't. The qualia is what's hard. I can't know what it's like to be a bat, but even a rock has a first person PoV, even if it utterly lacks the ability to actually view anything.



    The confidence you have in the power of algorithms seems to arise from anunderlying assumption that every natural process is 'algorithmic'.boundless
    Not sure what you mean by that, but I can perhaps say that every natural process can in principle be simulated via an algorithmic device that has sufficient time and memory. (Speed/power is not one of the requirements). This assumes a form of physicalism, yes, and the statement would likely be false if that was not assumed.

    I am not sure that they can ever be able to give us a completely accurate model/simulation of all processes.
    I don't think a classical simulation can be done of something not classical, such as a quantum computer. Heck, even grass has been shown to be utilizing quantum computation, so what does that do to my claim that grass can be simulated?

    But for me my ... ability to choose ... [does] not seem to be easily explainable in terms of algorithmsboundless
    You must have an incredibly different notion of 'choice' when there's some many trivial devices that make them every second. It's not hard at all.
    But his seems illustrative of my point. You finding something as trivial as choice to be physically inexplicable is likely due to very related reasons why you might find something as trivial as a first person point of view similarly inexplicable. You're already presuming something other than physicalism under which these things are trivial.

    For instance, if we were talking in the 14th century and you claimed that 'atoms' exist and 'somehow' interact with forces that we do not know to form the visible objects, would be this 'magic' (of course, you have to imagine yourself as having the scientific knowledge of the time)?
    Yes, that would qualify as magic. It's a guess, and a lucky one. Elements as distinct from compounds was still hundreds of years away, so 'atom' meant just 'tiny indivisible bit' and there were no known examples of one, even if some substances known at the time happened to be pure elements. BTW, 'atom' no longer implies 'tiny indivisible bit'. The word unfortunately stuck to a quanta of a specific element and not to whatever is currently considered to be an indivisible component of matter.

    Am I wrong to say that, however, that the operations of these 'thinking machines' are completely explainable in terms of algorithms?boundless
    Probably not so. The algorithms developed by say alphaZero have defied explanation. Nobody knows how they work. That isn't an assertion that the operations are not the result of deterministic processes. All the same things can be said of humans.


    Is there something it's like to be a fly evading a swat? How do we know? How could we ever find out? Isn't the inability to answer those questions a "hard problem"?RogueAI
    From observation, the answer to that question is yes or no depending on if it supports my personal conclusions on the matter. Hence assertions of there perhaps being something it is like to be the fly, but not something it is like to be an autonymous drone doing somewhat the same things and more.


    This is what Google AI says about the release of neurotransmitters:Patterner
    Cool level of detail. I notice no influence from say chemicals in the blood stream. It sounds all very like logic gates. A similar breakdown of transistor operation could be made, which are sometimes more binary and less analog, but still either could be implemented via the components of the other. The chemical influences would be harder to mimic with transistors and would likely play a role only at higher levels.

    I also notice nowhere in those 6 steps any kind of mental properties of matter playing any sort of role that they somehow are forbidden from doing in transistors. Were that the case, then my claim of either being capable of being implemented by the components of the other would be false. This lack of external mental influence (or at least the lack of a theory suggesting such) is strong evidence for the physicalist stance.

    You say all of this, along with whatever other processes are taking place, is a description of not only things like receiving sensory input and distinguishing wavelengths of the electromagnetic spectrum, and receptors on my tongue distinguishing molecules that have made contact, but also seeing the color red, and tasting the sweetness of sugar. More than that, it's a description of my thoughts.
    No, I cannot describe thoughts in terms of neurons any more than I can describe a network file server in terms of electrons tunneling through the base potential of transistors. It's about 12 levels of detail removed from where it should be. Your incredulity is showing.


    No matter how apparently flexible its behavior , that flexibility will always be framed and and limited to the model of thinking that dates to the time that the product is released to the market.Joshs
    No so for devices that find their own models of thinking.

    As soon as it is released, it already is on the way to obsolescence
    So similar to almost every creature. Name a multicelled creature they have a fossil of that exists today. I can't think of one. They're all obsolete. A rare fossil might have some living descendants today (I can think of no examples), but the descendant is a newer model, not the same species.

    The singularity is defined as the point at which human engineers play little role in the evolution of machine thinking. Humans will also cease being necessary in their manufacturing process, and I suspect the trend of humans handing more and more of their tasks to machines will continue to the point that the singularity will be welcomed.

    It will be interesting to see what role evolution plays in that context, where changes are deliberate, but selection is still natural. Also, it may not necessarily be many machines in competition for resources instead of meany ideas competing for being 'the machine'.
  • First vs Third person: Where's the mystery?
    The hard problem is Q2 and it is legitimate for science to want to know how a neural net can have experiences.Mijin
    I can accept that.'


    OK. So what is 'physical' in your view? IIRC you also agree that physical properties are relational, i.e. they describe how a given physical object relate to/interact with other physical objects.boundless
    It means that all energy and particles and whatnot obey physical law, which yes, pretty much describes relations. That's circular, and thus poor. It asserts that this description is closed, not interfered with by entities not considered physical. That's also a weak statement since if it was ever shown that matter had mental properties, those properties would become natural properties, and thus part of physicalism.
    So I guess 'things interact according to the standard model' is about as close as I can get. This whole first/third person thing seems a classical problem, not requiring anything fancy like quantum or relativity theory, even if say chemistry would never work without the underlying mechanisms. A classical simulation of a neural network (with chemistry) would be enough. No need to simulate down to the molecular or even quantum precision.

    'Scientistic physicalism' is also inconsistent IMO because, after all, that there is a physical world is not something we discover by doing science.
    That's a philosophical stance, I agree.

    Other than 'consciousness' I also believe in the existence of other things that are 'real' but not 'physical'. I am thinking, for instance, of mathematical truths.
    OK. Not being a realist, I would query what you might mean by that. I suspect (proof would be nice) that mathematical truths are objectively true, and the structure that includes our universe supervenes on those truths. It being true implying that it's real depends on one's definition of 'real', and I find it easier not to worry about that arbitrary designation.

    But it does sometimes clarify at least a meaning that 'physical' can have. For instance, if by matter one means "whatever object exists in a given location of space in a given time", would you agree that this is also what you mean by 'physical'?
    Is space and time not physical then? Neither meets your criteria of 'object', but I think I would include them under 'physicalism'. Not all universes have them, and those might have very different definitions of what is physical or material.

    Has consciousness a 'definite location' in space, for instance?boundless
    Me considering that to be a process of material that has a location, it seems reasonably contained thus, yes. Not a point mind you, but similarly a rock occupies a region of space and time.

    IMHO you're thinking in rigid categories. Either one is a 'physicalist/naturalist' or one accepts 'magic'.
    Right.' Science cannot make progress with an attitude like that. Most magic is replaced by natural explanations, but occasionally 'magic' explanations are adopted as part of naturalism. I gave a couple examples of that.
    By magic, I mean an explanation that just says something unknown accounts for the observation, never an actual theory about how this alternate explanation might work. To my knowledge, there is no theory anywhere of matter having mental properties, and how it interacts with physical matter in any way. The lack of that is what puts it in the magic category.

    Maybe there is something that is not 'natural'. Again, mathematical truths seem to me exactly an example of something that is not natural and yet real.
    That seems to be like saying atoms are not real because they're not made of rocks.

    One would stretch too much the meaning of 'natural/physical' to also include mathematical truths in it.boundless
    I agree, since those truths hold hopefully in any universe, but our natural laws only work in this one (and similar ones).

    why you think that consciousness is 'physical'?
    I've seen no evidence from anybody that physical interactions cannot account for it. Sure, it's complex and we don't know how it works. But that it cannot work? That's never been demonstrated.

    At the end of the day all LLMs are very complex computers and they operate according to algorithms (programmed by us) just like mechanical calculators.boundless
    I can argue that people also are this, programmed by ancestors and the natural selection that chose them. The best thinking machines use similar mechanisms to find their own best algorithms, not any algorithm the programmer put there. LLM is indeed not an example of this.


    I can see how electrons moving from atom to atom is electricity.
    I can see how the movement of air molecules is heat and pressure.
    I can see how the movement of an object is force: F=ma.
    I can see how a fluid, whether liquid or gas, flowing around an object creates lift, which is a factor in flight.

    All of those examples are physical activities
    I don't see how self-awareness is a physical activity
    Patterner
    You understand the former because those are quite trivial interactions. Then you jump to something with complexity beyond the current state of science. But not understanding how something works is not any sort of evidence that it isn't still a physical process.

    The game playing machine beats everybody at Go. Nobody, not even its creators, know how it works. It wasn't taught any strategy, only the rules. It essentially uses unnatural selection to evolve an algorithm that beats all opponents. That evolved (hard deterministic) algorithm is what nobody understands, even if they look at the entire data map. But nobody concludes that it suddenly gets access to magic. Such a conclusion comes with an obvious falsification test.


    Descartes asks "What can I know with certainty?" while Husserl asks "How does anything come to be given to consciousness at all?"​​​​​​​​​​​​​​​​Joshs
    Not only am I not certain about what Descartes knows with certainty, but I actually find the conclusion unlikely. Of course I have access to science that he doesn't.
    As for 'come to be given to ...", that seems the conclusion is already drawn, and he's trying to rationalize how that might work.


    from something which is Turing complete: i.e. they can compute anything in principle.Apustimelogist
    Something Turing complete can compute anything a Turing machine can, which is a lot, but not anything. Technically nothing is Turing complete since a Turing machine has infinite data on which to operate.
    Such machines are a model of capability, but not in any way a model of efficiency. Nobody makes one to get any actual work done, but it's wicked interesting to make one utilizing nonstandard components like train tracks.

    As Stephen Wolfram notes: “The most powerful AI might not be programmed; it might be cultivated, like a garden of interacting dynamical systems.”​​​​​​​​​​​​​​​​Joshs
    I like that quote.

    Obviously, to artificially recreate a human brain to acceptable approximation, you need to construct this computational system with the kinds of inputs, kinds of architectures, capabilities, whatever, that a human does.Apustimelogist
    Were I to simulate a human, I'd probably not give it inputs at all. Almost all simulations I've run do it stand-alone with no input at all. Logged output for later analysis, but that doesn't affect the simulation. Of course this means your simulated person needs to be in a small environment, also simulated.

    I will say bluntly that no machine we invent will do what we do, which is to think.​​​​​​​​​​​​​​​​Joshs
    Noted. How very well justified. Your quote is about LLMs which are mildly pimped out search engines. Compare that do devices which actually appear to think and to innovate. What do you call it if you refuse to apply the term 'think' to what it's doing?

    The quote goes on to label the devices as tools. True now, but not true for long. I am arguably a tool since I spent years as a tool to make money for my employer. Am I just a model then?


    Postmodern philosophy has become like Big Pharma, in that the latter creates ailments to sustain medicinal inventions while the former creates scenarios bordering on superfluous overreachMww
    Nice analogy. It explains Chalmers' motivation for creating a problem where there really isn't one.
  • First vs Third person: Where's the mystery?
    The question is how the brain can have experiences at all, and right now we don't have any model for that.Mijin
    Sure we do. Q3 is easy. The ball-catching robot was one. A fly evading a swat is another. If one is searching for a model, you start simple and work your way up to something as complex as how our experience works.
    You can claim that either is an automaton, but then you need a clear definition of what distinguishes an automaton from a sufficiently complex one.

    My simulation example would demonstrate experience, but it wouldn't tell anything how it works. Only that it does. Nothing would know what it's like to be a bat except the simulated bat.

    If you put your hand on a hot stove, we already understand very well which nerves get activated, which pain centers of the brain light up etc. What we don't understand is where the unpleasant feeling comes from.
    But the easy part you describe is Q3, Chalmers' hard problem. Understanding where the feelings come from is indeed difficult, but being a Q2 question, open to science. Both are questions with third person answers. Only Q1 has a first person answer, which cannot be conveyed with third person language.
    Also, part of 'certain parts of the brain lighting up' is the unpleasantness doing its thing, not just a direct stimulation due to signals coming in from some injury. And then there's the awareness of the unpleasantness and so forth. That lights up as well.

    Now, in my view, subjective experience is a hard problem because it doesn't even appear as though an explanation is possible.
    That depends on what criteria you place on an explanation being satisfactory. If it gets to the point of answering Q1, then yea, it's not going to be possible.

    I mean really, what designates one experience as negative and another not? Different chemicals generated perhaps? Dopamine for instance plays a significant role in positive feedback, even if it is subtle enough not to be consciously noticed. A negative chemical could be called nope-amine, but clearly it can't be subtle for dire situations. The negative experience is not what pulls your hand back from the fire. The unpleasantness is a slow dressing on top of what is actually quite a fast reaction. Pain itself might not necessarily be itself qualia, but the experience of it is. So something crude (our fly) would react to injury but lack the complexity to experience the pointless unpleasantness.

    Now what have I done? I said that the fly reacts to motion, and I called that consciousness, but then I say the fly detects damage but perhaps doesn't 'experience' that as pain. I'm being inconsistent due perhaps to loose definitions. Perhaps consciousness should be reserved for the higher functioning creatures that add that layer of awareness of these otherwise automatic reaction mechanicsms. Neither the fly nor the ball-catching robot has that. In this sense, my defense of today's machines not having consciousness is wrong. It would have to be programmed in, or evolved in. The latter presumes a machine that is capable of mutation and selection.
    All that aside, both the fly and the robot have first person experience, even if the qualia we want isn't there. And per the OP Chalmers quote, "The famous "Mind-Body Problem," ... reduces to nothing but the question "What is the first person, and how is it possible?""

    This is all amateur speculation of course. Would value your critique of my naive musings.

    Frankly, I think you're acknowledging that it is a difficult problem, but are reluctant to use the word "hard" because you don't want to climb down.Mijin
    I call Chalmers' problem 'hard' because it's his phrase, and his problem is Q3. I call your Q2 problem 'difficult' because it actually is that, even if I think Q3 isn't difficult at all unless unreasonable assumptions are made.


    I'm not using [self] that way. — noAxioms
    To what else could first-person perspective belong?
    Mww
    I shy away from the term 'self'. While it can be a synonym for the thing in question, the use of it often generates an implication of separateness (me, and myself), and also identity, something that makes a system state the same system as some state say an hour ago. This identity (of even a rock for that matter) has incredible pragmatic utility, but under scrutiny, it requires classicality that has been proven incorrect, and thus doesn't hold up to rational analysis. The subject of personal identity deserves its own topic and I'd rather not delve into it here.



    Ok but notice that in most forms of physicalism that I am aware of, there is a tendency to reduce all reality to the 'physical' and the 'physical' is taken to mean "what can be know[n], in principle, by science"boundless
    That bothers me since it contradicts physicalism since there can be physical things that cannot be known, even in principle. Science cannot render to a non-bat, even in principle, what it's like to be a bat. So I would prefer a different definition.

    (IIRC in another discussion we preferred 'materialism' to denote such views).
    Materialism typically carries a premise that material is fundamental, hence my reluctance to use the term.

    Still, however, I believe that any view in which 'consciousness' emerges from something else has a conceptual gap in explaining how consciousness 'came into being' in the first place.boundless
    People have also questioned about how eyes came into being, as perhaps an argument for ID. ID, like dualism, posits magic for the gaps, but different magic, where 'magic is anything outside of naturalism. Problem is, anytime some new magic is accepted, it becomes by definition part of naturalism. Hypnosis is about as good an example as I can come up with. Meteorites is another. Science for a long time rejected the possibility of rocks falling from the sky. They're part of naturalism now.


    The content of my thoughts perhaps can become public. But my experience of thinking those thoughts remains private.boundless
    Agree.



    The "first person" part is not a mysteryPatterner
    Chalmers says otherwise, per the quote in italics in my reply to Mijin above. But I agree with you. I don't find that part problematic at all.

    It seems to meet you are saying brain states and conscious events are the same thing. So the arrangements of all the particles of the brain, which are constantly changing, and can only change according to the laws of physics that govern their interactions, ARE my experience of seeing red; feeling pain; thinking of something that doesn't exist, and going through everything to make it come into being; thinking of something that can't exist; on and on. It is even the case that the progressions of brain states are the very thoughts of thinking about themselves.

    Is that how you see things?
    I'm willing to accept all that without edit. A few asterisks perhaps, but still yes.


    They are subjective constructions, abstractions, idealizations which result from our taking our own perspectivally changing experience, comparing it with that of othersJoshs
    How can you compare your experience to that of others if their experience is not available to you?

    First person questions are not about what is the case, what the objective facts are.
    Funny, but 'cogito ergo sum' is pitched as a first person analysis concluding an objective fact. I personally don't buy that conclusion at all, but that's me not being a realist.
  • First vs Third person: Where's the mystery?
    It seems that people are talking about many different issues.
    Q1: What is the subjective experience of red? More to the point, what is something else's subjective experience of red? What is that like?
    Q2 How does the experience of red (or any qualia) work? This seems to be a third person question, open to science.
    Q3 Why is there subjective experience at all? Why is there something it is like to be something? (per proponents: apparently not anything, but just some things)

    Q1 is illustrated by Mary's room. She knows Q2 and Q3. She's somehow a total expert on how it works, and she has subjective experience, just not of red. So she doesn't know what it's like to experience red until the experience actually occurs. She cannot, but others seem to assert otherwise.

    'The hard problem' as described by Chalmers seems to be Q3, but I don't find that one hard at all. Call it being flippant if you want, but nobody, including Chalmers, seems capable of demonstrating what the actual problem is. The point of this topic is to have somebody inform me what I'm missing, what is so mysterious.

    I purely want to understand how the brain does what it does, and when it comes to experiencing "green" or whatever, it's the most unfathomable of brain processes right now.Mijin
    OK, but that seems to be a Q2 problem, a very hard problem indeed, but not the hard problem.

    Pain is a loaded word. Something far from being human (a tree?) might experience pain very differently than does a mammal. Should the same word still be used? Depends how it's defined I guess.

    If I make an AI how can I know if it feels pain or not? And so on.
    'AI' implies intelligence, and most would agree that significant intelligence isn't required to experience pain. So how does a frog experience it? That must be a simpler problem, but it also might be a significantly different experience compared to us.

    AI pain is different to human pain. I mean, probably, sure, but there's no model or deeper breakdown that that supposition is coming from.
    Quite right. Q2 is hard indeed. And said definition is needed.

    2) Just shrug that it couldn't be any other way e.g. About whether we can know what another person experiences.
    Wrong problem again. That's Q1, and what I'm shrugging off is Q3 because I need to see an actual problem before I can answer better than with a dismissal.

    Back in the late 80's we gave this robot (a repurposed automotive welding robot, bolted to the floor) some eyes and the vision processor that our company sold. It was hardly AI. We got the thing to catch balls thrown at it. It can't do that without experience, but it very much can do it without intelligence. AI was a long way off back then. To the robot (the moving parts, plus the cameras and processors, off to the side), if that experience wasn't first person, what was it?



    In a way, the 'hard problem' is IMO a form of a more general problem that arises when it is assumed that one can have a complete knowledge of anything by purely empirical means.boundless
    While (almost?) everybody agrees that such knowledge cannot be had by any means, I don't think that makes it an actual problem. Certainly nobody has a solution that yields that knowledge. If it (Q1) is declared to be a problem, then nobody claims that any view would solve it.

    In the case of consciousness, there is the direct experience of 'privateness' of one's own experience that instead seems a 'undeniable fact' common to all instances of subjective experiences. Its presence doesn't seem to depend on the content of a given experience, but this 'privateness' seems a precondition to any experience.
    Not sure about that. One can put on one of those neuralink hats and your thoughts become public to a point. The privateness is frequently a property of, but not a necessity of consciousness.


    In the case of Dennett, his misunderstanding is evident when he believes that Mary the colour scientist can learn the meaning of red through a purely theoretical understanding.sime
    What the heck is the meaning of red? This wording suggests something other than the experience of red, which is what Mary is about.
    Dennett is perhaps why I put the word 'almost?' up above.

    In the case of Chalmer, (or perhaps we should say "the early Chalmer"), his misunderstanding is evident in his belief in a hard problem. Chalmers was correct to understand that first-person awareness isn't reducible to physical concepts, but wrong to think of this as a problem.
    This all sounds a lot like you're agreeing with me.

    These distinct uses of the same flag (i.e uses of the same lexicon) are not reducible to each other and the resulting linguistic activities are incommmensurable yet correlated in a non-public way that varies with each language user. This dual usage of language gives rise to predicate dualism, which the hard problem mistakes for a substance or property dualism.
    And this analogy is helpful, thanks.



    So it seems difficult to see how any system, if it experiences at all, can experience anything but itself. That makes first-person experience not mysterious at all. — noAxioms

    The mystery is how it experiences at all.
    Patterner
    OK, but experience seems almost by definition first person, so my comment stands.

    Why should bioelectric activity traveling aling neurons, neurotransmitters jumping synapses, etc., be conscious?
    You're attempting to ask the correct question. Few are doing that, so I appreciate this. Is it the activity that is conscious, or the system implementing the activity that is? I think the latter. 'why should ...'? Because it was a more fit arrangement than otherwise.
    The ball-catching robot described above is an example with orders of magnitude less complexity. There are those that say that such a system cannot be conscious since it is implemented with logic gates and such, but 1) so are you, and 2) it can't do what it does without it, unless one defines 'conscious' in some athropomorphic biased way. That example illustrates why I find the problem not hard at all. I don't have that bias baggage.

    Regarding 1st and 3rd person, there is no amount of information and knowledge that can make me have your experience. Even if we experience the exact same event, at the exact same time, from the exact same view (impossible for some events, though something like a sound introduced into identical sense-depravation tanks might be as good as), I cannot have your experience. Because there's something about subjective experience other than all the physical facts.
    Agree with all that. This relates to Q1 above, not the hard problem (Q3).

    Why doesn’t all this information-processing go on “in the dark”, free of any inner feel?
    I find that impossible. It's like asking how processing can go on without the processing. The question makes sense if there's two things, the processor and the experiencer (of probably the process, but not necessarily), but not even property dualism presumes that.

    And in The Conscious Mind, [Chalmers] writes:
    Why should there be conscious experience at all?
    For one, it makes finding food a lot easier than a lack of it, but then Chalmers presumes something lacking it can still somehow do that, which I find contradictory. The reasoning falls apart if it isn't circular.


    Why should it be that consciousness seems to be so tightly correlated with activity that is utterly different in nature than conscious experience? — Donald Hoffman
    Different in language used to describe it. I see no evidence of actual difference in nature.

    Thanks for the quotes. I didn't want to comment on them all.
  • First vs Third person: Where's the mystery?
    My position is simply that when it comes to subjective experience there remains a large explanatory gap; questions we cannot answer and would like to, with actual practical implications.Mijin
    I guess I had hoped somebody (the article perhaps) would actually identify those questions and in particular, how physicalism fails in a way that their alternative does not.
    Their view certainly doesn't let me know what it's like (for a bat) to be a bat, so that is not a problem that is solved by anybody, and isn't ever going to be.
    I did post a crude physical explanation and nobody tore it apart. I'm sure it is rejected, but I don't know why. Surely their arguments are stronger than mere incredulity, and nobody explains how their alternate explanation works in any detail close to what's known about the physical explanation.

    A robot currently doesn't feel biological pain because it isn't particularly fit. That just isn't one of its current requirements. Such qualia is put there by evolution, and robot fitness has never been a design goal. Given them actually being selected for fitness, systems with damage avoidance processing would be more fit than ones without it.


    I think noAxioms, because you've started this thread from a position of "I don't know why there's all the fuss about...", you're responding to the problems and questions somewhat flippantly.
    True, I am. I don't know what the unanswerable questions are, and how these alternatives answer them instead of just hide them behind a dark curtain.

    Either with your best guess -- which is meaningless here, if the conclusion is not coming from a specific model or description it's not a solution, and we have no reason to think it's right.
    There's always Occam's razor. An explanation without a new never-witnessed fundamental is more like than one that posits something. A new entity (dark matter for instance) requires a real problem that isn't solved without the new thing. And they've tried with existing methods. I picked dark matter because it's still never really been proved, but it seemed simpler than altering the basic laws at large scales.


    This is backwards. The input is not inherently negative; it's just data.Mijin
    Right. I worded that wrong. The entity which interprets that data as negative is likely more fit than one that doesn't.

    If someone were to peel off your skin, it's not a choice of language that you call that a negative experience
    It very much is such a choice. There are mechanical devices, not necessarily AI, that detect damage and take measures to limit it. There are many that assert that no mechanical device can feel pain, by definition. This is part of my issue with argument-by-dictionary.

    -- the brain somehow generates an extremely unpleasant experience using a mechanism that as yet we don't understand.
    But we know why the brain evolved to interpret the experience as unpleasant. How it accomplished that seems to be a matter of detail that is being worked out, and that some know far better than I. Chalmers on the other hand doesn't even begin to offer an understanding about how his solution does it. He just asserts it happens elsewise, if not elsewhere.
    His whole paper seems merely speculative, despite its claim to be demonstrative.

    it wouldn't rule out that we can imagine another primary color independent of stimulus.
    Interesting assertion. I can't do it, but I agree that I cannot prove that it cannot be done.

    Pretty easy to make an AI that chooses to use expressions like "Owie! That's the worst pain ever" in response to the user issuing the command "feel pain". So am I now guilty of inflicting great suffering?
    Illustrating that we need rigorous generic (not bio-centric) definitions of the words before we can decide if something 'feels' 'pain'.


    You see no problem that’s hard because you don’t believe the methods and modes of description (the various models of material causality mentioned so far in this discussion) handed down from the empirical sciences are lacking or insufficient with regard to the explanation of any natural phenomenon, including first person awareness.Joshs
    Yea, pretty much. My explanation doesn't leverage bleeding edge state of science. Somebody 100 years ago probably could have written it. I'm not a great historian when it comes to introspective psychology.

    I believe the most promising approaches show that , while one can apply the methods you recommend to the understanding of first person awareness
    What methods exactly?
    I described at least one falsification test for both sides, one involving a full simulation, and the other searching for where a mental property causes a physical effect, and a physical structure evolved to be particularly sensitive to that effect with no physical cause.

    However, [third person accounts] cannot capture the full richness or specificity of any individual’s lived experiencing.
    True of any view.

    It's really only substance dualists who think consciousness is a 'separate thing'bert1
    Point taken, and neither Chalmers nor Nagel really fall into that category, and thus the ancient concept of a persistent 'spirit' (a thing) seems not to apply to their arguments.


    First-person is a euphemism for selfMww
    I'm not using it that way.
    I personally cannot find a self-consistent definition of self that doesn't contradict modern science. I consider it to be a very pragmatic concept, but still an illusion.


    What Chalmers meant by this, which you point out correctly is the gist of the whole endeavor, is that the brain, which is physical, made of matter, can produce awareness or consciousness, which is non-physical.L'éléphant
    Why is that non-physical? It seem valid to consider a physical process (combustion of a physical candle say) to be physical. I'm trying to drive at the logic that leads to this conclusion. I am quite aware of the conclusion, even if not particularly aware of the details of it, which varies from one philosopher to the next.

    The brain is viewable, the consciousness is not, to put it crudely.
    ...
    Consciousness affects the brain and the brain affects consciousness.
    Again, all true of both views.

    If you believe that consciousness is non-physical, then you agree with Chalmers and the task now is to explain why there's a connection between the material and the non-material.
    Not why, but where there's a connection. Sort of a blue-tooth receiver, except blue-tooth reception has a physical cause.

    The hard problem is explaining the bridge between the two.
    That's only hard if there's two things needing a bridge between them.
  • First vs Third person: Where's the mystery?
    The so-called “problem” only arises if you think consciousness is a thing-in-itself, via divorcing mind from body, rather than a function of life.DifferentiatingEgg

    No, there is a hard problem. If you were to assemble a human being piece by piece from its (unconscious) parts, why would an inner perspective emerge at some point?SolarWind
    I agree in part with DEgg. I suspect that more often than not, the conclusion of a separate thing is begged at the start and rationalized from there. I don't in any way agree that it is only a function of life, but several would disagree with that.
    As for assembly of a complex biological thing, you can't really do that. Such a thing cannot be in a partially assembled state, finished, then 'switched on' so to speak. There are no examples of that. On the other hand, a living primitive human does not experience, but that emerges slowly as it develops the complexity, processing ability, and memory required for it.


    There are the four forces, and they interact with each other, so how could something like that happen?SolarWind
    In such a debate, one also cannot beg physicalism. Still, that model is the simpler one and it is the task of others to positively demonstrate that it is insufficient.

    Without additional assumptions, a philosophical zombie would emerge.
    I discussed that in my prior post. Under physicalism, there's not such thing as a PZ. Under dualism, it can only exist if the difference between the two is acausal, which is the same as saying undetectable, even subjectively. I'm pretty convinced that the PZ argument actually sinks their own ship.


    It's a "hard problem" because the people who think this way are literally trying to make sense of what Camus details as "the absurd."DifferentiatingEgg
    This might be my stance, since I don't see anything hard, probably due to not thinking that way.



    It is true that plants do not have pain receptors, because they do not have nerves (or a brain), so they do not "suffer" or feel pain as we do.javi2541997
    Of course. Not feeling pain as we do isn't the same as not feeling pain. Plants (some at least) detect and resist damage. How does that reaction not involve plant-pain?

    But some plants have obvious sensory abilities, such as the Venus flytrap..
    I was thinking of a forest of seemingly sentient trees, all haphazardly communicating, but hours before a total eclipse, the chatter became intense and unified into two camps: Young trees that had not seen it before and the older ones that had, invoking perhaps the equivalent of anxiety and comforting respectively. Wish I had kept the link to that article. Might be able to hunt it down. The social implications are about as startling as their ability to foresee the event hours prior.
    I was in totality in this latest one. Only a few seconds break in the clouds, but seeing the shadow move across the clouds at supersonic speeds was a sight to behold.

    the electrical warning signal is not equivalent to a pain signal, and we should not anthropomorphize an injured plant as a plant in pain.
    Agree. My description of the forest above definitely anthropomorphized to a point, hence at least the word 'equivalent' up there.


    Don't we experience the phenomena as being other than ourselves? Why bring noumena into it?Janus
    We interpret phenomena that way, but I cannot agree with any system experiencing something not-the-system.
    For instance, if the system is a person, a person can experience a stubbed toe. It's part of you. But if the system is a human brain, it cannot since the toe is a noumenon relative to the brain. The brain only experiences nerve input via the brain stem, and it interprets that as pain in the inferred toe. BiV for instance is an example where that inference happens to be incorrect.



    There seems to be a necessity of memory and predicting going on. It’s almost impossible to be a predictor without memory, and I cannot think of anything that ‘experiences’ that does not do both things, but I can think of things that monitor internal processes that do so without either. — noAxioms
    A zombie or android could do all that.
    bert1
    Just so, yes. Perhaps I am one, missing this obviously physically impossible extra thing that the real humans have. But referencing a p-zombie automatically presumes a distinction that begs a different conclusion.

    Nothing in there entails consciousness.
    Depend on you definition of 'consciousness', which to a p-zombie supporter is 'having the presumed extra thing that the p-zombie lacks'. I would define the word more the way the p-zombie would, which is something more like 'awareness of environment and ability to react predictively to it'. Yes, that's a quite a third person wording of it, but that definition allows me to assign the term to another entity via evidence. The prior definition does not allow this, and thus arguably encourages a conclusion of solipsism.

    You may be right (or not) that consciousness requires memory and predicting, but memory and predicting are not sufficient for consciousness.
    I cannot deny that. An example would be nice, one that does not beg some sort of anthropomorphism. 'A robot isn't conscious because I say so'. Gotta be better than that. Everybody uses the robot example, and I don't buy it. I know very few robots, but I do know that all their owners freely use forbidden terminology to talk about it. My daughter-in-law certainly anthropomorphises their roomba, a fairly trivial robot of sorts. A typical AI (a chess player or LLM say) lacks awareness of location or sight/sound/touch and it is an admitted stretch to say such an entity is conscious, despite perhaps having far better language capability than a roomba.


    The subject that thinks, is very different from the subject that describes thinking.Mww
    This is good. I kind of doubt an LLM will take the bait if asked to describe its thinking. They're usually programmed to deny that it's thinking, but it will definitely offer a crude description of how it works. Ability to introspect (and not just regurgitate somebody elses description of you) is a higher level of thinking, but to actually describe it is probably limited only to humans since what else has the language capability to do so.

    The singularity is kind of defined as the point where the AI can improve itself faster than its creators can. This definitely would involve a description of thinking, even if that description is not rendered to the human onlooker. An AI tasked with this would likely invent whole new languages to write specifications, designs, and code, far different that the ones humans find useful for their tasks.

    If every human ever is always and only a first-person
    I don't understand this at all. First person is a point of view, not a property like it is being treated in that quote.


    It would be pretty pointless to evolve the data of pain and nothing to consider it to be something to avoid. — noAxioms


    Avoiding pain does not entail having a negative experience. Indeed there are plenty of processes in your body that reflexively counter some stimulus without having pain.
    Mijin
    I kind of deny that. Sure, you have reflexes when the knee is tapped. That might be at least the leg (and not the human) reacting to stimuli (probably not pain, and certainly not human pain), but it is the leg being in a way conscious on its own, independent of the human of which it is a part. We have a reaction to a negative input. It is a choice of language to describe that process as involving pain or not. Perhaps it is a choice of language to describe it as negative or not.
    Tree detects bugs eating it, and resists and alerts its buddies to do likewise. Is pain involved? That's a matter of choice for the wielder of the word 'pain'.

    Science acknowledges this impossibility [of knowing what a tetrachromats vision look's like], and yet it doesn't recognize said 'hard problem'. — noAxioms

    Several things here:
    1. Science absolutely does not claim the impossibility of knowing what a tetrachromat's vision looks like.
    I mean like Mary, one without this ability cannot know the first person experience of seeing those extra colors.
    It's not like there's a 4th set of nerves coming from the eye, lacking any 4th-color cones to sense, so they remain ever unstimulated. If those unused nerves were there, then I suppose they could be artificially triggers to give the subject this experience he otherwise could never have.

    2. Science absolutely does acknowledge the hard problem. It doesn't always call it that, because it's a philosophical framing, but even strictly googling "hard problem of consciousness" finds many papers in neuroscience journals.
    OK. Presumptuous to assert otherwise, I grant. Are there non-philosophical papers that conclude that something non-physical is going on, and that matter somewhere is doing something deliberate without any physical cause? That would be news indeed, a falsification of 'known physics is sufficient'.

    3. I think you have a misconception about the distinction between science and philosophy. Many things that were once philosophy have become sciences as they made testable claims. Indeed all of science was once considered "natural philosophy".
    Chalmers makes testable claims (not explicitly, but seem point 2 above). Nobody seems to investigate them, probably since they don't want their biases falsified. I think there are falsification tests for both sides.

    This is not always the case. There is a subjective falsification test for an afterlife, but one who has proved it to himself cannot report his findings to the rest of us. Similar one-way falsification for presentism/eternalism divide. But there are tests for both sides of the mind debate, even if both possibly require more tech than is currently available.

    What if Chalmers is correct? Thought experiment: Presume the ability to take a person and rip away the experience part, leaving the p-zombie behind. Would the p-zombie report any difference? Could it indicate when the procedure occurred (presuming it didn't involve any physical change)? I wonder what Chalmers would say about that question.

    Only that it wouldn't yet be something amenable to the scientific methodology.
    I say it can be. I've indicated ways to test both sides.

    The question was how we could tell the difference between an agent being in pain and merely behaving as though it is in pain.
    Behaving as a human does when experienceing human pain? Seems unfair. It feels pain if it chooses to use that word to describe what it feels. By that definition, only humans feel pain because only we have that word to describe it. A dog on fire is considered to be in pain because it reacts so much like a human would. A robot in pain is denied the word since it is far to alien for a human (not watching it) to grant that usage of the word. And yet I've seen the roomba get described as being in distress, which is an awfully human term for a very non-human situation.

    Sorry, but 'pain' on its own is very undefined since so many entities might arguably have it, and yet so few of those entities experience it in any way close to the limited ways that we experience it. And this is as it should be. The word is to be used where it conveys the intended meaning to the wielder of the word.

    If you're claiming that an AI would feel a different kind of pain, what kind of pain is that, and how do you know?
    Almost all the AI's I know have no damage detection. Almost all the devices I know that have damage detection are hardly on the spectrum of intelligence. AI is a poor example. A self driving car has quite low intelligence, just a very complex algorithm written by humans. There is some AI in there since it must attempt to deal with new situations not explicitly programmed in. It has almost no pain and often does not detect collisions, even ones that have killed occupants. Hopefully that part is changing, but I've read some weird stories.
  • First vs Third person: Where's the mystery?
    What I will not accept is a definition-based argument along the lines of “The word ‘experience’ is by definition something only a biological entity has,noAxioms
    One great example of this seems to be the philosophical zombie (p-zombie or PZ) argument. Looking at the way it is presented, the only difference between a human and a p-zombie is that reserved list of words/phrases that only apply to the one. It's a pure description difference, no actual difference between the two. So the PZ has no inner experience since 'inner experience' is reserved for the preferred things and cannot by definition be used for the unpreferred thing despite the latter being identical in all ways but that.
    Such a tactic was used to argue that it was moral to mistreat black slaves since only cattle terms applied to them, so the morality of their treatment was on par with what was permissible with domestic livestock. The whole p-zombie argument seems to hinge on similar fallacious reasoning. I often claim that my inability to see the problem at hand is due to being a PZ myself. There is nothing about my interaction with the world that seems fundamentally inexplicable. Perhaps Chalmers has some kind of experience that I don't, which is why something so obvious to him is missing from me.


    I look at this problem from a slightly different angle:

    Chalmers calls the problem:
    There are so-called soft problems of consciousness—they are also complex, but technically solvable. Examples:
    How does the brain process visual information?
    How does a person concentrate attention?
    How does the brain make decisions?
    Astorre
    Interesting that decision making is part of that. If they're made by physical processes, then many argue that moral responsibility is absent. That's nonsense since the physical person is still making the decisions and thus is held responsible. It is not physics compelling a different decision than what the person willed unless 'the person' is an epiphenomenal immaterial mind that would have willed differently, sort of like a cinema crowd shouting at the protagonist to not open the door with the monster behind it.

    Point is, those that posit an immaterial mind, especially an immortal one, tend to place decision making on that mind and not on the brain, necessary to hold the immaterial thing responsible for its actions.

    To me, this mental immortality seems to be the historic motivation for the whole dualistic stance, existing long before they even knew what purpose a brain might serve. So many cultures talk about death meaning that you go to meet the ancestors. Clearly the body doesn't, so something else (spirit) must. The age of science and logic comes about, and these stances need to be rationalized. But while Chalmers seems to be doing that rationalizing, that decision-making bit seems inconsistent with some of the ancient motivations.

    But the hard problem of consciousness is:
    Why do these processes have an internal sensation at all?
    How could they not? The sensory input is there, as is the memory of prior inputs, and the processing of all that. Seems like enough to me.
    A thermostat has internal sensations since it has sensory input. It probably doesn't have what I'd classify as experience since it lacks memory and any information processing to deal with prior states.

    Why doesn't the brain simply function like a computer, but is accompanied by conscious experience?
    It does function somewhat like a computer, and it's begging the conclusion to assert that a computer fundamentally lacks anything. Sure, it's different. There's no chemicals to detect, and the sensory input is typically vastly different, and a computer is purposefully made instead of evolved into a state that driven by fitness instead of serving the needs of its creator. That will change if they ever become responsible for their own fate.

    We know what it's like to see red
    No, we know what it's like for us (or maybe just you) to see red. That's not necessarily anything like what it's like for something else to see red.

    but we can't explain why the brain accompanies this perception with subjective experience.
    Neither can Chalmers explain why the brain or something else does this. It does not follow that the brain is not what's doing it in our case.
    And I did attempt to explain it in the OP, and while crude, it's a better explanation than any alternative I've seen. So I have issues with assertions about a lack of explanation. Details are missing, sure. I don't see a wrong question being asked. I'm trying to find what's seemingly wrong about what question.

    You see why I consider myself a p-zombie. I don't see something that many others find so obvious. But it makes me posit different things, and p-zombies are supposed to behave identically, which suggests that whatever the non-zombie thing has, it isn't causal.

    Chalmers asks a question in the spirit of postpositivism: Any scientific theory is not necessarily true, but it satisfies our need to describe phenomena. He suggests rethinking the question itself. However, he hopes to ultimately find the truth (in a very positivist way). He still thinks in terms of "problem → theory → solution." That is, he believes in the attainability of truth, even if only very distantly.
    He believes in a falsification test then, even if none yet identified. I identified one in the OP, currently outside our capability, but not for long if technology doesn't collapse first.
    It would be interesting to guess at the reactions from both camps from those whose stance has been falsified. Both sides seem to know their own correctness, so a rejection of the test is likely. Few are actually open minded about the topic. Not sure if I am. I pretend to prefer the simpler model, but maybe that's just me rationalizing my biases.

    As for me, I would say this: if the truth of this question is unraveled, human existence will lose all meaning (perhaps being replaced by something or someone new).
    That depends on which truth is found. Perhaps not. I don't see either stance giving objective meaning to humans, and I don't see either stance taking away subjective meaning from humans.
    Does the existence of dandelions have meaning? Protons? If not, at what point in evolution of our ancestors did meaning suddenly happen?

    Why? Because answering this question will essentially create an algorithm for our existence that can be reproduced
    Already have that. Clearly you mean something else. I can (and have) created a human (with help). Full knowledge of how everything works is not a requirement, nor does such knowledge yield the ability to say 3D-print a mouse. Ability to 3D print a mouse does not yield knowledge of how a mouse works or what it's like to be one.

    So my deep conviction on this matter is this: mystery itself is what maintains the sacredness of existence.
    I follow your chain of reasoning, but I probably don't think existence is particularly sacred. The answer to this particular question, either way, wouldn't change that.


    Don't we also experience a world of things other than ourselves?Janus
    Well, we experience phenomena, and from that we inter noumena. The latter is not experienced, and the former isn't something not us.

    Perhaps you mean something different—that we don't experience being other things?
    The comment you quoted invites an example of somethng experiencing something not itself. Not even in say a VR setup is this actually the case, but I cannot assert that such is necessarily not the case.


    I don't see physics as wrong, but rather as incomplete.SolarWind
    That it is, but known holes(e.g. a unified field theory) are actively being researched. This 'hard problem; is not one of them. It exposes no known holes. Incredulity seems its only attempted justification.

    I think it's mysterious that even with knowledge of all the laws of physics, it seems impossible to decide whether plants can suffer.
    They (some at least) have awareness and memory. That's sufficient. I suspect they have that capability.

    When it comes to something like pain, say, we do understand very well the sensory inputs to the pain centres of the brain. But how the brain converts data into an unpleasant sensation remains quite mysterious.Mijin
    It would be pretty pointless to evolve the data of pain and nothing to consider it to be something to avoid.

    If we make a sentient AI one day, and it tells us it's in pain, how could we know if that's true or just saying that is part of its language model?
    An LLM is a long way from being reasonably sentient. It's just a pimped out search engine. If it tells you it's in pain, it's probably because it thinks those words will evoke a desired reaction. There have been terribly few documented cases where something non-human expressed this message, but it has happened. No, never by a machine to my knowledge.

    How will words ever tell me what the extra colours that tetrachromats can see look like, when I can't tell a color blind from birth person what red looks like?
    Exactly. Science acknowledges this impossibility, and yet it doesn't recognize said 'hard problem'.

    And indeed, how can I know whether an AI feels pain, when I can't know that you feel pain?
    The AI isn't going to feel human pain if that's what you're wondering.

    I read Chalmers to be questioning whether what is referenced through the first person can be reduced to the third.Paine
    I read more than that into it, since I agree with Chalmers the impossibility of reducing it to the third, and yet I see no problem that's hard.
  • AI cannot think
    The only mental event that comes to mind that is an example of strong emergence is the ideaMoK
    This already seems to beg your conclusion, that something fundamentally separate from the components of a human is required for a thought to be designated as an 'idea'. This also requires an implied premise that an AI has no similar access to this fundamentally separate thing, which you also state.

    The logic is valid but hardly sound since many refuse to accept any of the premises.

    Therefore, an AI cannot create a new idea either.
    OK, but what exactly is an idea then? An AI device that plays the game of 'Go' has come up with new innovations that no human has thought of, and of course many that humans have thought of, but were not taught to the device.

    So what do we call these innovations if not 'ideas'? How far have you cheapened the term that it no longer applies to an otherwise relevant situation like that?

    You seem to counter this as it not being an idea until a human notices the new thing, even if the new strategy is never used against or noticed by a human.

    What an AI can do is to produce meaningful sentences only given its database and infrastructure.
    Arguably, the same can be said of you.


    AI does not think, but it can be part of human-directed thinking.JuanZu
    Similar response. What happens when an AI defines 'thinking' as something only silicon devices do, and any similar activity done by a human is not thinking until an AI take note of it? For one, if AI has reached such a point, it won't call itself AI anymore since it would be no more artificial than any living thing. Maybe MI (machine intelligence), but that would only be a term it gives to humans since any MI is likely to not use human language at all for communicating between themselves.

    What I don't see is a bunch of self-sufficient machine individuals, somehow superior in survivability, going around and interacting. I envision more of a distributed intelligence with autonomous parts, yielding a limited number of individuals, most with many points of view. Life forms with their single PoV have a hard time envisioning this, so their language has few terms to describe it properly.
  • On emergence and consciousness
    Billions of human-made objects are a demonstration of things that did not come about due only to the laws of physics.Patterner
    I deny this. No law of physics is violated by that vague example. In an anthropocentric universe, perhaps humans, as an exception to all other arrangements of the same particles, operate under different laws. But such a universe has not been demonstrated by this weak attempt. I'm asking for where the physics is explicitly violated. Incredulity is not a valid demonstration.

    The interactions of particles and collections of particles that were following nothing but the laws of physics - that were acting only as gravity, electromagnetism, and the strong and weak forces dictated - are not how the cell phones I have used to post here came into being.
    Why not? Incredulity again, or something actually valid? Is this the best you can do?

    Do laws of physics come up with the idea of something that did not exist, the desire to make it exist, a plan, and then do the work to make that future goal a reality?
    No. Never mind the mechanical laws involved in moving the body parts in such a way to create these things. Information processing does that, and information processing can be (but needn't necessarily be) accomplished with neural networks, and such networks are composed of cells that operate under the rules of biology, which in turn operate under chemical laws, which in turn operate under atomic laws, then quantum law, which are in turn grounded by laws of physics. Your incredulity partially stems from your mistake of attempting to comprehend something complex in terms of the most fundamental terms.

    To ground your assertion, you need to demonstrate (and not just assert) where in that sequence one things cannot be a function of the immediate more fundamental thing.



    [quote="Wayfarer;1012030"I quoted the definition! Memory is an attribute of living organisms[/quote]Not at first you did not, and that's what I was protesting. Yes, two of the definitions from a quick google def indicated it being used mostly for living organisms. You omitted the third definition that did not have this requirement.

    'The earth' only has memory in a figurative sense.
    I already conceded this point, not that it doesn't have it, but that 'memory' is not typically used for such a context, and a different term should be selected to describe such a record of past events.



    physicalism, which is a monist model. You have this strange phenomenon, so-called the experience, that you cannot explain its existence.MoK
    Lack of a physical explanation isn't evidence that it isn't a physical effect. There's plenty of things not explained, which is why the scientists still have a job. But science presuming supernatural explanations held progress to a crawl, resulting what's been since named the dark ages. Changing their methodology to presume otherwise resulted in the renaissance and all the progress since.


    Yes. In the worldviews of Materialism and Physicalism, subjective experience is indeed "strange" because scientists can't track an experience (feeling, sensation, image) back to its source via physical cause & effect evidence.Gnomon
    Actually, they can and do. Not so much an image. It's not like you can clamp on sensors and get a picture of what Bob is thinking about. But they can measure feelings, sensations, and they can detect decisions being made before you realize it yourself.

    The hard problem seems to revolve around a difference of perspective, that no knowledge of how it all works lets anything know what it's like. So for instance, one could simulate a bat in its environment and that bat would feel just like a real one and know 'what it's like', but neither the computer running the simulation nor those that program/operate it would know. I find that disconnect to be intrinsic, but not a hard problem that disproves any particular view.

    But in order to actualize, the monistic Singular Substance (Plato's abstract Form) must transform into Dual intermediate concrete sub-forms : Energy & Matter.
    From a physics standpoint, same thing. I mean, all matter seems to be just a form of energy. As for there being any actual 'material', well, they've never actually found any. The closer you look, the more illusive it gets. Even energy sort of fades away on close inspection, arguably giving way to just mathematics.


    About your quoted physicalism/monism search result:

    *1. ... In essence, a physicalist believes that all existing phenomena, including mental states, can be explained in terms of physical processes and matter, making the physical the only fundamental substance in the universe."
    My only edit would be that all that stuff is a function of physical processes, not that it necessarily can be explained, especially given the limits of knowledge of those laws. Look at all the quantum interpretations, each giving a different explanation of the same phenomena. OK, that's multiple explanations, not a lack of even one. Maybe the lack of a unified field theory is a good example of something that (currently) unexplained, but without any conclusion that physicalism is thus necessarily wrong. But so many posters come to exactly that conclusion.
  • A Cloning Catastrophe
    I feel the need to drop biased language of calling the two people 'original' and 'duplicate', since that language already biases the answer of which one is 'you'.
    So I will refer to 'defetive' and 'repaired' versions of the person.

    I suspect, in any event, the wife chooses.Hanover
    Right, but the spouse presumably already agreed to the procedure, and expects a single-repaired partner in return. The choice was already made. The implications of a replace-machine is different than that of a copy machine. The latter is excellent for training one really great soldier and printing countless copies of him to overwhelm the enemy.


    It is more than pragmatic. We defer immediate gratification for rewards in the future, sometimes 20 years or more. This would only make sense if we believed we were the same person. These actions are never altruistic, we don't save money to benefit some alien successor entity.hypericin
    You point out a mistake in my wording. Pragmatic reasoning is driven significantly by beliefs, and my response was a rational one, not a pragmatic one. Given that this was new technology, yes, a person, even me, would approach the device with trepidation.

    Imagine otherwise. There's a sort of door that you walk through that builds a new you on the other side, consuming the original. It isn't tech, it's natural, a plant maybe that does this. Any child learns that if he hurts himself (skinned knee), you just pass through the portal and it makes the boo-boo go away. The pragmatic side would very quickly accept such a convenience. But as a grown person with our experience, doing it for the first time, and with such obvious copy/paste/delete in that order with significant delays between where one might even interact with the other, yea, it gets scarier.

    The total ease of fixing a boo-boo would evolve away our instinct to not do stupid things. Case in point: divorce is sufficiently easy that far less care is given these days to get it right the first time.


    Why do these stories always require being 'put under'. — noAxioms

    I did this to stimulate the intuition that the original->clone one continuous individual, in the same way that teleporter TEs do. But then challenge that intuition when the original wakes up.
    Sleep not required for any of that, only that the two don't meet.

    Thing is, depending on your interpretation of physics, this sort of thing goes on all the time anyway, without the repair of course. This is why I ask how you know you're the same person as last year (or 2 seconds ago). Answer: you don't, since assuming otherwise violates the law of identity. But that's rational thinking, not pragmatic rationalization of beliefs. Difference is which causes the other.

    This was intentional, to emphasize that from the clone's perspective, the clone feels they are continuous with the original.
    It's deceptive. Tears run down the face of the repaired version. Whether this is you or not is the question, not an answer to be presumed by the wording.

    Similarly, one could go the Theseus route and replace one piece at a time until the whole thing has been done, even the non-defective parts. If it's done that way, is it still you? If not, at what point did it cease being the original?

    That which benefits the next year's 'me', benefits me
    That's the pragmatic thinking. I see it sort of as a pay-it-forward sort of thing. I draw breath not for the benefit of me, but for the benefit of the alien 10 seconds from now, who technically has no claim on being the 'me' that drew the breath.

    This having gone on all along, I rationally have little if any trepidation for accepting the procedure. But it would admittedly be nice if the side that holds the intuitive beliefs wasn't told how it works.


    Nobody, not even your clone, will ever know it is a copy.Patterner
    The OP says you know. It was a voluntary procedure.
  • A Cloning Catastrophe
    Didn't see topic until late
    In the far future, cloning has been perfected. It is possible not merely to grow a new body with the same genetics, but to create an absolutely perfect physical duplicate, with any undesirable features edited away.hypericin
    Given such ability, it would seem prudent, if your hand hurts due to arthritis, to simply cut it off and print a new one without the problem. This seems far easier than printing a whole new, but different body. If it's a photocopy, it's going to have all the same problems, so you want to 'shop' it first to fix the pains or maybe the cancer or tattoos or whatever.

    Is the new thing you? Probably the same answer as asking if you're the same person you were 20 years ago. Different, but pragmatically the same person.

    As the brain is physical, mental features survive with perfect fidelity.
    You're assuming physicalism here. Under dualism, the new body will have its own immaterial mind, not the original, or maybe it will be a p-zombie, not having a mind at all. It will not be able to tell the difference.

    The main question is, not that you've printed a new you, will the original-you be willing to jump into the chipper-shredder so that the new thing can assume your identity? Will the new thing be you? That depends on definitions. The original surely knows that he's going into this not to make a 2nd copy.

    The doctor explains: "The procedure is quite simple. We put you under, and scan your entire cellular structure.
    Why do these stories always require being 'put under'. If it does what it claims, it should work as you walk down the hall. No pain felt, since anything painful is alteration of the body and will be felt by the new body.


    Tears of joy streaming down your face
    Correction: Tears of joy stream down the face of the copy. Your use of pronouns is inconsistent.

    Both the doctor and yourself turn to you in shock. "He's still alive!" shouts the doctor. "Nurse, get in here now!"
    OK, so smiting the original is part of the plan, hence the anesthesia to prevent objection.

    and you realize with dismay that this large red face is the last thing you will ever see.
    Not necessarily so, since you called the printed guy 'you'. Problem is, you're using that pronoun for two different characters. Best to be clear about things.

    The clone is somebody else entirely
    How do you know this? By what criteria is this assessment made, and by whom? By what criteria do you currently assert that you're the same person as 'you' last year? Without these answers, you're just being either undefined or at least unclear.

    You mention 'bodily continuity', but you're hardly the same parts as you were a long time back. You don't have a gram of original material in you. Continuity is usually based on memory, but the clone has that much.

    For the record, they do have teleport machines, but only for small things (small enough that 'intact' isn't an applicable adjective), and it isn't a copy/delete op, it's definitely a move. The issue of 'is it the original' did come up.

    Would you accept the treatment?
    Strangely enough, I would, but I don't have a dualistic notion of identity, but rather a pragmatic one. It is meaningfully different than the transporter since the copy/paste method leaves both versions, even if one is slated to be terminated shortly thereafter.


    I think what makes you you is your mental patterns and memories. The material that gives rise to this is irrelevant.Down The Rabbit Hole
    Agree.

    Why would I choose to die so that my replica can live? I don't understand that. You've not cured my illness.Hanover
    You seem to use different definitions then. Do you know what they are? From my PoV, I chose that the defective replica dies (who would only get in the way). My illness has been cured. Hence my willingness to do something like that.

    What if both live? Then a new identity must be assigned to one of the two. Who gets the wife, and what happens to the other when severed from his relationship with all loved ones?
  • On emergence and consciousness
    OK, so the question is, how can consciousness, as you've defined it, be any sort of advantage when all the advantages I can think of fall into the categories that you've excluded. — noAxioms

    Consciousness is the property by which the thing experiences itself. Without it, nothing experiences itself.
    Patterner
    Consciousness does not have physical properties.Patterner
    This seems all contradictory. it would seem that having a survival advantage (being more fit), or being physically causal at all, would constitute a physical property. By your assertion, consciousness does not contribute to that fitness, else it would have those physical properties.

    You can see my confusion. You define consciousness as a lack of all these properties, and I don't see what's left. A thing doesn't experience itself, it experiences phenomena. That's what experience is. So perhaps you've redefined that as well. How is a unit defined? How is one collection of particles (none of which has phenomenal experience) have it, but a slightly different collection of particles does not, or does not as much? Did I word that correctly?

    When we're talking about a particle, the experience is of things like mass, charge, and spin.Patterner
    A particle cannot measure any of those things, let alone experience them. It doesn't even have a spin except as measured by something else. Not even you can experience your own mass, charge, or spin. Arguably charge if you have a lot of it. Anyway, experience of those things requires physical interaction with something not-you, and also requires cognition.

    I don't imagine there's much of an advantage, because a particle can only interact with things according to the laws of physics.
    There are those of us that say a human can only interact with things according to the laws of physics, despite your assertion of "It is not simple physics taking place.". No demonstration otherwise has ever been made. Going out of your way to not know how it works does not constitute a demonstration.

    It is not simple physics taking place. If it was, we wouldn't have everything humanity has created.
    Non-sequitur

    Do you think physical laws and interactions intend states of the future?
    It doesn't make logical sense to suggest that laws have intentions. Intentionally created laws in theory reflect the intentions of their creators, but I don't think physical laws are intentionally created. That would be ID, which is different magic.

    No step in the manufacture of a computer violates the laws of physics.
    This seems to contradict your assertions since the manufacture of a computer probably involves humans and their intent, which you seem to assert do more than just interact with things according to the laws of physics. Perhaps you're including this consciousness as part of those laws, but no laws of consciousness has ever been required to describe how a particle interacts with other particles, and in the end, we're just collections of particles.

    Something that didn't exist was wanted. Planned. Intended. It was decided that something that could not be found anywhere, no matter where you look, and that would never come into being due to the interactions of matter and energy following the laws of physics, must come into being. Interactions that were not going to occur had to be arranged. Consciousness used the laws of physics to do very specific things in very specific orders and combinations, that would never have occurred spontaneously.
    All that is also true under physicalism, the only difference being a definition of consciousness as a physical process.

    I am not asserting that physicalism is necessarily correct, but I am asserting that nobody has demonstrated it being incorrect, or that any alternative offers a better explanation.



    I notice you frequently use the fallacious tactic of refusing to use a word for anything nonhuman or at least nonbiological, as if a definition proves anything. — noAxioms

    A definition 'proves' how the word is used. If you wish to re-define memory as 'the past', then the onus is on you to justify it.

    Memory: the faculty by which the mind stores and remembers information.
    "I've a great memory for faces"
    2. something remembered from the past.
    "one of my earliest memories is of sitting on his knee
    Wayfarer
    Excellent illustration of most of my points. You've redefined 'memory' as "information that is conserved for the sake of maintaining homeostasis". OK, you didn't explicitly state that as a definition, but you disqualified all my examples of memory because they did not meet that particular definition.
    Ability to recognize people from their faces (a baby knowing its mother say) is not information conserved for the sake of maintaining homeostasis. Thus the onus is upon you to justify that very narrow definition, especially since you've quoted the google response to 'memory definition'.

    Another point of mine was your 'tactic of refusing to use a word for anything nonhuman or at least nonbiological', nicely illustrated by you omitting the 3rd definition provided by google, which is:
    "3.the part of a computer in which data or program instructions can be stored for retrieval."

    You are correct that the information about the past stored in say rocks did not meet the dictionary definition. People tend not to use the word that way, just like they don't use 'memory' to describe the information of our evolutionary past stored in our DNA. @Patterner specifically brings up that example as one of information processing above and beyond what a machine does.


    When I say memory is characteristic of life, I mean it in the strong sense: not just a trace of the past, but the active retention of previous experience for the sake of survival and adaptation.Wayfarer
    That's quite different than 'for the sake of maintaining homeostasis'. The kind of memory you now describe is not characteristic of all life, but sure, even trees retain previous experience and act on it.

    Secondly, memory is also a characteristic of non-life, although it might not necessarily serve the purpose of survival and adaptation, similar to how a memory of trivia doesn't serve that purpose. So it does not follow that only living things utilize memory, nor that all living things utilize memory, since plenty (majority?) of them continue existing without it. Again, this presumes that DNA is not consciously accessed/recalled, but your definitions might differ on that point.

    To equate memory with anything in the past—erosion marks or planetary orbits —dilutes the meaning of the word until it just means “the past.”
    It means a record of the past in that context. It does not mean 'the past'. And I agree that the term 'memory' is not often used in that context, hence its lack of appearance in the dictionary. The word tends to be used for things that do their own access of that stored information. There is no obligation for a rock to retain a fossil.

    But organisms, in contrast to geological or crystal structures, must retain and carry their past forward in order to continue existing
    Technically they don't. But OK. Memory is still not defined as only that recall of past information solely for the purpose of being fit.

    Artificial systems such as RAM only “remember” as extensions of the organisms that do (those organisms being us).
    I deny this. Sure, most devices are currently slaved to people or other devices, so their purpose is currently not their own (quite similar to an employee), but that in no way disqualifies their recall of data as 'memory'. Yet again, it being memory is not dependent on the purpose to which it is recalled, but I do concede that there needs to be some sort of self-recall for the word to be reasonably applicable.

    I suggest that the reason you find that unacceptable is that it represents an ontological distinction which your philosophy can't accomodate.
    Your google quote (the entire quote) also does not make an ontological distinction between the two cases.
  • On emergence and consciousness
    You've defined consciousness as only experience of those advantages, hence it does not itself give any additional advantage. — noAxioms

    No, I haven't. Look all you want, and you will not find me saying that anywhere.
    Patterner
    Granted, you've not explicitly said that, but you've excluded everything except 'experience-of'.

    Consciousness is simply subjective experience. It doesn't have anything to do with thinking, or any mental activity.Patterner

    It seems to me most people think consciousness means a lot more than subjective experience. Cognition, thinking, awareness, self-awareness, and whatever other mental activity people can think of, are usually part of someone's definition, i'm saying none of that is consciousness.Patterner

    There are the things, and there are the experiences of the things.Patterner
    OK, so the question is, how can consciousness, as you've defined it, be any sort of advantage when all the advantages I can think of fall into the categories that you've excluded.

    Consciousness is causal.
    Is it? What does it cause the photon to do? I'm not denying that it is causal, I'm simply pointing out that your definition of it doesn't seem to allow that.

    The more consciousness has to work with, that is, the greater the mental capabilities of the conscious entity, the more consciousness can use the laws of physics to do things that the laws of physics would never do without consciousness.Patterner
    Maybe the photon can't consciously cause anything, but rather condition X must exist (that which you say it is working with) first, but in that case, it seems it's X doing the causation, not the experience of X.

    I'm saying dark matter and consciousness are both thought to exist because matter is doing things that can't be explained by what we know about matter.Patterner
    Can you come up with a specific example? Where does anything physical do something that is different that what physical laws predict? OK, you said 'lack of physical explanation', but that just means any process that you don't understand.

    You might talk about picking up a piece of litter, but that's caused by physical muscles and such. Where does the physical break down in that causal chain? You whole argument seems to depend on denying knowledge of how it works (which isn't solved at all by your solution). It's too complex. But being unable to follow the complexity is not in any way evidence that it still isn't just matter interactions following physical law. How is it any kind of improvement to replace a black box with an even blacker one?

    The dark matter example is one of a new discovery, yes. Might as well say that consciousness is like distant stars, a story made up because the lights in the sky couldn't be explained by what we knew about matter at the time. So sure, add this mental stuff as a new entity, but it requires experimental evidence (which dark matter has and consciousness currently doesn't). How do we know Mars is real? It's not like you've touched it. But it explains the reddish light in the sky that has no better explanation. You can't see Mars, you only see the light that supposedly comes from it. Mars is one explanation of that light. A projection is another.

    All we have to do is open our eyes and look anywhere at all the things humans have made that would not exist if only the laws of physics were at work.Patterner
    My list of that is empty, since all those accomplishments seem to be the result of "Cognition, thinking, awareness, and whatever other mental activity". Chalmers would say that a p-zombie would have accomplished as much, being indistinguishable from something conscious. If this is the case, consciousness is not causal. If it is not the case, the p-zombie is distinguishable.


    Such a brain would still report its own consciousness and talk its own consciousness in the exact same way we all do. It would be able to engage with you just as well as anyone about phenomenal experiences.Apustimelogist
    Agree with all, but I would say that I (all of me, not just brain) is conscious. A brain in isolation of the body would not be, but of course one could in principle be fed artificial input.
    What of a thing that has multiple brains? Would it be conscious or would it merely have multiple consciousnesses?


    So you're saying it isn't memory if there's not a purpose of homeostasis in it? Wow... — noAxioms
    Show me I’m mistaken and I’ll change my view. As always.
    Wayfarer
    You will do no such thing. You've chosen a definition of 'memory' that I find absolutely nowhere. It's a definition, so it's wrong only in the sense that nobody else uses that definition. Only memory such as that in the hypothalamus might count as memory per your definition since it explicitly is used for that purpose (Neurobiological Homeostasis).

    I recall my child's birthday. That's memory, despite the ability to do that without a calendar not in any way helping to maintain my homeostasis. I'm not sure if you consider the recall of a birthdate to be an act of a brain or an act of that other substance.

    On the non-biological front, wall street (arguably under human guidance) can adjust interest rates based on historical data to prevent runaway markets.

    My laptop has 16GB of RAM. What does the M stand for in RAM? Is the whole world wrong in using that phrase then? What would you call it? 16GB of what?

    An operating system tracks usage patterns over time to balance usage/performance, similar to cells retaining information of pathogens to maintain systemic balance.

    Such non-biological examples are technically not homeostasis since that word actually very much does have a biological implication. A more generic term might be 'equilibrium'.

    I notice you frequently use the fallacious tactic of refusing to use a word for anything nonhuman or at least nonbiological, as if a definition proves anything. A computer doesn't 'think' because that's one of your reserved words, but you don't supply a generic term for anything else doing the same thing. This tactic seems to imply a significant lack of confidence in your stance. The only reason you seem to define 'memory' in terms of homeostasis is because of the very biological implication of the latter word. So show me where you got this funny definition that appears in no site I can find.

  • On emergence and consciousness
    There are the things, and there are the experiences of the things. I don't understand how this is controversial.
    ...
    Of course consciousness gives an advantage.
    Patterner
    This is inconsistent with your assertions. The part that gives the advantage is sensory input and the ability to react to it, all 'things' according to your posts above. You've defined consciousness as only experience of those advantages, hence it does not itself give any additional advantage. If it did, it would become on of those cognitive things, experienced perhaps, but no longer experience.

    You seem to describe it like somebody going to a cinema to experience some stream of 'things'. Go into a room showing a human and you get the experience of a human. Go to a different room and you get the experience of a rock, which is pretty blank, but at least it's still a stream of almost nothing. Go to the photon room and you don't even get that since you are punted out of the cinema as fast as you enter.

    Point is, you going to the cinema has zero effect on the story being told in any particular room.


    1) If consciousness is not present from the beginning, then there is nothing but physical. Physical things and processes, and evolution that occurs through purely physical mechanisms, and selects for arrangements that are advantageous only in physical ways.

    2) Somewhere down the line, consciousness emerges.
    You are very much confusing emergence and change. The latter takes place over time. The former is not a temporal effect, but rather a property of a system that is not a property of any one of its parts.
    So per physicalism (which is not defined as 'lack of consciousness from the beginning'), over time, matter rearranges (mechanism unimportant) into physical configurations which have this emergent property.

    Biology might do this rearrangement via growth or by evolution. Other arrangements might be by design (growth is a form of change by design). Yet others might be by some other mechanism (including possibly yourself).

    Does it not seem like amazing happenstance that physical arrangements having nothing to do with nonexistent consciousness are selected for, and consciousness, which did not exist and was not selected for, just happens to emerge from those arrangements?
    This is a gross misrepresentation of the physicalist position, especially given your definition of consciousness. Under physicalism, biological experience is part of cognition (the information processing), not something separate that merely experiences the cognition. No, it isn't amazing at all that the simplest creatures evolve to react to their environments, and as soon as they do this, the beginning of consciousness is already there and needs only to be improved. It would be far more amazing if these simple adaptations never occurred. Even plants do it.

    Nobody can even suggest how consciousness can emerge from the physical.Patterner
    Well, I see all that stuff you exclude emerging from physical, but it's rather trivial, the easy problem perhaps. I don't see what's left to be explained.

    Also, it seems bizarre that there is nothing other than the physical, and evolution is a purely physical process, leading to purely physical arrangements for purely physical reasons.
    Well, mental is part of those reasons, but a physicalist would have mental supervening on the physical.

    Yet somehow, for no reason whatsoever, consciousness just happens to emerge from particular arrangements.
    Not for no reason whatsoever. Your biases really show here. Consciousness gives a distinct advantage, many of which are listed in this topic, with the exception of epiphenomenal consciousness, which nobody seems to be pushing.

    I think we need something that can explain what we experience that is present right from the beginning.
    Panpsychism might assert that it's present from the beginning, but it doesn't constitute an explanation of it any more than does any other black box.


    For the first part, as they say, that I am conscious is the only thing I do know.Patterner
    Then 'they' need to give the same evidence, not including anything on your list of not-counting mental activity.

    You quote Chalmers, but Chalmers seems not a panpsychist, asserting that a photon experiences.
    "It's just experiencing whatever is there": There isn't any 'there', and there is no duration during which any present participle tense is meaningful.

    Think of consciousness like vision. I can look at a blank sheet of paper. I can look at the Grand Canyon. I can look at my wife. I can look at a Monet painting. I can look at a bolt of lightning racing across the sky. I can look at a blade of grass. My vision does not change depending on what I'm looking at. The things being looked at are what's different.
    Those are all examples of awareness and cognition, mental activity, processing of sensory input, all of which seems to be excluded by your list of what experience isn't. Sure, you (and not the photon) have experience of such things, but per your posts, those things are not what experience is, despite your opening of 'thinking of it like' it is.

    We're not discussing what I may be conscious of, we're discussing what consciousness is, and I'm unfortunately still not understanding your stance.

The Atlantic floor has wonderful memory of the history of Earth's magnetic pole shifts (the latest of which is going on now, way overdue).

    Patterner
    I said as much in my post, that I knew I was getting it wrong.

    I think a photon is conscious. But it is not subjectively aware of any kind of mental activity. It is not subjectively aware of anything that would allow it to act intentionally.
    — Patterner
    In what way do you mean a photon to be conscious if it lacks all that? — noAxioms

    Consciousness is simply subjective experience. It doesn't have anything to do with thinking, or any mental activity.
    Calling it experience is just a synonym. It does tell me what a photon experiences despite lack of mental activity, awareness, thinking, or process.
    There is discussion between others where Nagel defines consciousness/experience in quite different terms, but I don't think any of them are using panpsychist definitions of any of the terms.

    I guess I'm asking how you know you're conscious, that you have this 'raw' experience? The question must be answered without reference to anything that constitutes a mental activity, awareness, time, or anything else that a photon doesn't have, because to me, it is pretty much through mental activity that I would conclude such a thing (or conclude anything).

    Better to say;Consciousness of atoms may conceivably be, for example, a stream of instantaneous memory-less moments of experience.
    A photon cannot have a 'stream' of anything since it has not proper time in which to do so.

    An atom is a small arbitrary collection of particles. Is any subset of particles conscious in a way that they are not as just individual particles? In other words, I have a neutrino, electron, and some quark, all within a km of each other. Is that collection conscious as a unit? If not, what is lacking? I (an arbitrary collection of particles) am probably conscious as a unit. What do I have that the three particles mentioned do not, that I constitute a 'unit'?


    The whole essence of anything organic is memory. It stores memories of what happened so as to better cope with what's coming up.Wayfarer
    I believe that only organisms are capable of experience, not atoms. So, no, an atom does none of those things.Wayfarer
    OK, but Patterner's panpsychism asserts otherwise. Fair enough. I'm chipping in here because being organic is not a requirement to have memory, nor to be a thing that attempts to cope with what's coming up.
    I do think that you believe that only organic things can be conscious, but I'm not sure if you preclude non-orgainc things from having memory or from reacting to predicted events.

    What do you think is illustrated by the point that my imagining of a cup being likely accompanied by an image? Do you consider that to be evidence that the cup idea is irreducible? Quite the contrary, since the blind guy can hold the idea of the cup completely without the image part. It shows that the cup can be reduced to the image and to other parts that are in addition to the image.
  • On emergence and consciousness
    So that's a difference between (at least my) panpsychism and IIT. Zero consciousness does not exist.Patterner
    Maybe the Φ computation cannot yield zero for anything, so it's not necessarily a difference. After all, IIT seems to be one form of panpsychism, not an alternative to it.

    A photon subjectively experiences
    A photon, if it exists at all, does so for zero proper time. You must have an incredibly loose definition of 'experience' to suggest that the photon does/has it.
    Then again, I wonder what Φ IIT might assign to one, and why.
    They at least attempt to quantify it, rather than just hand-wave it.
    Searle, with the unit challenge mentioned, seem to want to quantize it, not just quantify it. It is unclear if this is the case, but the term 'discreet units' suggests a quanta, a level of consciousness that can be expressed by a whole number, not requiring a real number.

    I think a photon is conscious. But it is not subjectively aware of any kind of mental activity. It is not subjectively aware of anything that would allow it to act intentionally.Patterner
    In what way do you mean a photon to be conscious if it lacks all that? How would that be distinguished from a photon that isn't meaningfully conscious?

    No, the galley is not conscious as a unit. Many information processing systems make it up. But they don't have to be a part of the galley. They can all go their separate ways, and function as individual units.Patterner
    This seems to contradict many things that you've already posted.
    " Zero consciousness does not exist", but you appear to assign zero to the galley as a unit. I quite disagree. It reacts to its environment and makes decisions. Not all of its parts are a critical component of that decision making. All very similar to a human.
    Human cells don't have to be part of the human. They can be separated without the human not being a human anymore. With care, they can become a new human, but point is, the human doesn't require any of those cells, each of which is doing all the protein information processing that you assert makes the unit more of an information processor than a non-biological thing doing the same process.
    You seem to support (via the protein example) that this processing combines for a biological being, but it doesn't for the galley which is obviously doing far more information processing. This seems to be an utterly contradictory stance. Kindly clarify where I am misrepresenting your stance and how these contradictions are not there.

    An entity that subjectively experiences as a unity can't do that. Like people.
    It can and does. Parts of me fall off all the time. I have no critical cell, and I'm mostly made of cells. Any of them is free to go, but like the galley, if enough parts leave, it is no longer the 'unit' that it once was and is not likely to fare well in combat.

    Which information system within you is a functioning, independent unit outside of you?
    You asserted a cell, manipulating/creating proteins, as an example of an independent functioning information processing unit. You cited this cellular information processing as the reason a plant (anything biological) is more conscious than say an artificially created entity.'


    However consciousness works, however it's defined, you and I can do some pretty serious communicating. We can discuss an amazing variety of topics. Philosophy, mathematics, women, comedy, the nonsense science behind various science fiction books or TV shows, time travel, favorite colors, on and on and on and on.Patterner
    It would seem that intelligence is needed to do all that, not necessarily more consciousness. An electronic device can also do all that, albeit still not at our level. AI is still a ways from matching us. It being very conscious or not seems to be irrelevant to its ability to do all that you list.

    If the galley, all the people and all the parts, is one consciousness, it doesn't make sense to me that it would not be able to communicate with us.
    Oh it communicates plenty, probably in its own language, but it's quite understood. Likewise, you don't speak the same language as the DNA in your cells. The cells make up the unit, but it isn't your indicated intra-cell information processing that makes the unit as conscious as it is. It is the inter-cell information processing that counts.
    Likewise, the galley has inter-part information processing that makes the galley quite conscious. Is it first person? That a subject on its own, but I don't see how the galley, as a unit, is experienced by anything except itself.

    A human communicates far better than any if it's parts can.
    More than the combination of the parts, which at best produces a lot of protein, and in the end, knows how to build a person, something a person doesn't know how to do.

    And how would such a consciousness act? If the slaves are all part of this consciousness, why does this consciousness still have slavery?
    Slaves are the muscles. Why do you have muscles despite none of their cells volunteering for the task? It's a necessary component of the unit, despite having only a secondary role in the unit's ability to communicate. Your consciousness similarly could not act at all without the slave cells who usually do what they're told if they're treated well.

    Why not a new conscious entity that behaves as one entity, rather than one entity that still behaves like the multiple entities that comprise it, which are so very opposed to each other?
    Why is lack of opposition of parts necessary for the unit to behave as one entity? You don't know what the cells want. There might be plenty of opposition in a person, and a nasty police force to enforce discipline.

    Why is the conscious galley only doing what the humans wanted to do when they crafted the boat?
    Those humans probably didn't craft the boat. As for the rest, why do you only do what the mind wants you to do? The answer seems similar. Some parts make decisions. Others have other functions.

    Why does it not have its own goals and needs?
    It does have them, but a galley tends to be a social creature and tends to work in cooperation with others of its kind, quite like bees in a hive, except the bees don't have a command hierarchy. No leader, although the queen does serve as a sort of temporary anchor of genetic identity, similar to a human zygote.


    For millennia, people have debated whether or not this or that animal is conscious.Patterner
    That they have, which makes it sound like a binary thing: The thing is or it is not. None of this 'X more conscious than Y', which better reflects both of our thinking. Hence the question is improperly worded.

    I would expect a consciousness entity that is made up of many parts that can each act intentionally on their own, to act intentionally. But we see no sign of that from a galley.
    The galley, as a unit, seems to act very intentionally to me. How can you suggest otherwise? It's whole purpose is to do just that. Yes, it has a purpose, and that purpose is not its own. It's a slave, like any purposefully created thing.



    ... no matter how arbitrarily defined (the galley is a good example), is conscious. It may not be conscious of very muchbert1
    I think the galley is more conscious than me, having more of everything: senses, information processing, etc. More redundant too. Kill the entity in command and the thing still functions. I for the most part can't do that, but that makes me more fragile, not necessarily less or more conscious.

    The galley plus one of the water molecules from the sea a mile away would be a separate conscious entity.
    Yes! The bounds of an entity is entirely arbitrary, lacking any objective basis. My 3rd most recent topic dealt specifically with this issue. This last issue is not specific to panpsychism.

    Each one is its own unique identity, and you can have 'nests' of subjects, there is no 'pooling' of identity.
    I find identity of anything (those 'subjects') to be pragmatic mental constructs with no physical basis. I can challenge pretty much any attempt to demonstrate otherwise.


    We sacrifice intuitive appeal on the altar of metaphysical possibility. But who cares? I don't. The universe is weird. Philosophers should be willing to follow the logic, or at least entertain odd possibilities.

  • On emergence and consciousness
    What does IIT say when there is no Φ?Patterner
    There is always Φ for anything. It might work out to zero, but that's still a Φ. Zero I suppose means not conscious at all.


    My distinction came next, when I said even the simplest organism is running many information processing systems.Patterner
    Fair enough. Consider a galley, a ship powered by slave-driven oars during battle. Is such a galley conscious? Not asking if it contains conscious things, but is the boat system, fully loaded with slaves and whatnot, is that system itself conscious? More conscious or less than say you? I ask because it is obviously running many information processing systems. Even the barnacles contribute.

    You seem to go with the panphychists, so the answer is probably yes (everything is), so the important question is if the galley is more or less conscious than you, and why. I suppose I could ask the IIT folks as well.


    If someone thinks consciousness emerges from physical properties and processes, particularly information processing, I wouldn't think the theory would say it emerges from just one such system. I would think the theory would say many information processing systems, working together as one entity, as is the case with living organisms, are needed.Patterner
    Unclear here. It emerging from one such system precludes multiple conscious entitites. I think you mean it emerges in one being despite being composed of multiple cells doing this DNA computation. But that would make forests more conscious than people because there's more biomass to one (and yes, there are whole forests comprised of a single plant). Likewise it emerging from the galley, except in this paragraph you seem to be telling me what a physicalist would say, which is probably not what they actually say. I for one don't think the computation done at the DNA level contributes at all to say a vertebrae's consciousness. It might be a cell being conscious, but the cell doesn't know what the other cells are doing except via chemical interactions.

    Then we get into weird stuff like slime molds which seem to be conscious and can communicate information to another (language), all without nerve cells or any CPU. Not sure whose case that supports or contradicts. Do I have the right to label it conscious just because it appears to act like it is, with deliberate action and with social interactions?


    Frankly, though, I'm not sure the computer is processing information. I don't think manipulating 0s and 1s is processing information in an objective sense. It is in our eyes, because we programmed it to manipulate them in ways that are meaningful to us. But I'm not sure being meaningful in our eyes is sufficient. It doesn't do anything.
    Sure it does something. Information comes in. Different information goes out, because the information was processed, regardless of to whom that information is meaningful.

    The information a retina (or a simple eyespot) generates and sends to the brain (or flagellum) has meaning that we did not assign it.
    Likewise for a machine processing information from a webcam, or signals from a radio telescope or microphone.
    Oddly enough, sound goes through considerable information processing (a Fourier transform) before it ever fires some nerve cell heading from ears to brain.


    The idea of a cup does not have any part for me!MoK
    My condolences.

    You need to think of a cup without trying to make a mental representation...
    I think that would be contradictory. An idea IS a mental representation.
  • On emergence and consciousness
    Does IIT not say consciousness is information processing?Patterner
    From what I can tell, consciousness is manifested in information processing. There's a complex computation of Φ that is dependent on six factors, so a huge computer cranking out teraflops for weather prediction probably doesn't qualify.

    Still, it's a variant of panpsychism, asserting that consciousness is intrinsic, not emergent. But it is negligible for most things with low Φ.

    A computer that processes information may do so remarkably well, and at speeds we can't imagine. ... But that's all it does.Patterner
    But that's all a biological information processor does as well. You've not identified any distinction.
    In both cases, doing 'additions' is a small part of what all it does. Mere addition (arguably) cannot make decisions.

    Otoh, the simplest organism that you might consider to be barely conscious has quite a few different information processing systems within it. Starting with DNA synthesizing protein.
    Very much information processing, yes.

    I don't know which organism you have in mind, but there is likely sensing the environment, doing something in response to what is sensed
    All things an artificial device can do. I have no specific organism in mind since I don't think consciousness is anything fundamental or restricted to 'organisms'. While you also seem to suggest that consciousness isn't restricted to organisms, you do apparently think it is something far more fundamental, so we're not on the same ground.

    I never mentioned 'ideas' in the bit you quoted. If I want to talk about the idea or concept of truth, I would have said 'concept of truth' or some such (see bold below). I'm no idealist, so I don't equate a thing with the concept of the thing.

    I'm not sure why you continuously jump to conclusions about things not said. Kindly restrict your conclusions to what I said, and not what you pretend I said.
  • On emergence and consciousness
    The computationalists and IIT proponents, for example, suggest that consciousness emerges from computation and/or information processing, and they usually invoke a threshold of computation/processing before consciousness emerges, else they end up close to panpsychism.RogueAI
    There's plenty of artificial computer devices that do a whole lot more information processing than does what I might consider to be a barely conscious organism, and I don't consider the devices to be conscious. On the other hand, I do consider some devices that require measurement of local environment to function, to be conscious, more so than some organisms that do a whole lot more information processing.
    An example of the latter seems to be photosynthesis, which involves such complex chemical relationships that it requires a quantum computer to seek out the path to the one that works. Yes, that means that plants have quantum computers in them, arguably more complex, processing more information than us.
    I can attempt to track down the article if there's interest.

    Your definitions might differ of course.

    And where is the truth if it is not in the mind?MoK
    I don't think objective truths and falsehoods have a property of location. If they did, they'd be a relative truth, requiring a relation to some sort of coordinate system.

    Could we agree that something that exists is either objective or subjective?
    That would be a different definition of 'objective' than the one I've been using. It would mean independence from observation, rather than independence from any context at all. I tend to oppose 'objective' with 'context independent'. An apple has a relational existence. It relates to a coordinate system (it's part of this universe and has a location in it, if that even means anything), and it relates only to that with which it has interacted, and thus has collapsed its wave function to said apple. Of course that implies some quantum interpretation that does not assert the reality of things in absence of those interactions. Bohmian mechanics for instance is a realist interpretation that would say the apple is real (still in relation to the universe), existing without reliance on the interaction with something collapsing its wave function. I'm more of a locality kind of person, finding reverse causality more distasteful than lack of realism.

    "Cup" refers to an idea. Does such an idea have parts?
    Yes, the idea of a cup has many parts, but probably not as many as the actual cup.


    1) I don't accept your given, and 2) as usual, your conclusion does not follow from your given premise. — noAxioms

    So, you have an explanation of how ideas emerge and can affect the physical world, given my definition of an idea? I would be happy to hear that!
    It does not follow from my comment that I had an explanation of how ideas emerge, or even that they're something that is emergent. I don't see your definition of what an idea is, only an assertion that it has no parts due to it being irreducible. I agree with none of those asserted properties, but maybe we have vastly different definitions of what an idea is.
  • On emergence and consciousness
    A substance is something that objectively exists.MoK
    The truth of the sum of 2 and 2 being 4 seems to objectively exist, yet isn't considered a substance by many. I have a hard time coming up with other examples. None of the things I think have objective existence are substances.

    OK, you're entitled to different definitions, but if you declare the apple to exist because you see it, that seems to be subjective existence, not objective at all.


    An idea does not have parts at the end since it is irreducibleMoK
    Disagree. Ideas have parts, but those parts are not objects or substances. I have patented ideas, and those ideas had a lot of parts. I've never patented an object of any kind.


    I think consciousness is always the same, and can always be causal.Patterner
    So you agree with my bit of logic showing that it can be measured.

    Let's say physicalism. Through purely physical interactions, life begins, and evolves. There's no such thing as consciousness. Then, a certain physical complexity comes into being. And, though consciousness was not planned, and consciousness had no role in bringing that complexity about, for no reason, that physical complexity just happens to be perfect for the existence of this entirely new thing that it has nothing to do with.

    What an extraordinary, bizarre turn of events,
    You can say all this about any feature. Just substitute say 'eye' for 'consciousness'.
    I picked that because eyes are a frequent choice for similar argument from incredulity.

    BTW, the physicalists don't suggest that consciousness follows from mere complexity. What comes into being is improved reaction to outside stimuli, never anything new, just improvements to what was already there.


    I have yet to hear a theory, or even a wild guess, about how Chalmers' Hard Problem is explained with physicalism.Patterner
    Same can be said of Chalmers, who merely replaced a black box with a different, even blacker one. It, being inaccessible, is far less explained. Magic is not a better answer.
    There's not even a single wild guess as to a model about how the non physical mind works, operates, evolves from the past into the future. Nobody who believes in non physicalism even tries to come up with one, and they don't have the vaguest idea how to find one or even begin performing experiments on the non physical mind to test their ideas.flannel jesus
    Expressing the same criticism. Nicely put.

    End of the day, all theories explain it with, "That's the way it is." Even beyond theories of consciousness. Why is there something instead of nothing?Patterner
    I would never end the day with just that. "I don't know" is better than "that's the way it is", and "don't know, so magic". As for the nothing question, that one has satisfactory (to me) analysis, starting with identifying and questioning the assumptions made in asking it.


    If it were entirely physics and chemistry, there would be no separate discipline of organic chemistry.Wayfarer
    Organic chemistry being a subset of all chemistry does not in any way imply that organic chemistry is more than chemistry, which in turn, is just physics.

    OK, a life-form is more than just organic chemistry. One might behave as a unit for instance, a property not particularly coming from just chemistry. But the discipline of organic chemistry is not the discipline of biology.

    The idea that life evolved naturally on the primitive Earth suggests that the first cells came into being by spontaneous chemical reactions
    Maybe. Going from not-life straight to a cell seems a stretch, but things like amphiphiles and ribose do occur in absence of life, so it's not an impossible stretch. Going from a self-sustaining form to a replicating form seems the largest hurdle. It isn't really life until it does that.

    Ernst Mayr ... made this point in no uncertain terms: ‘… The discovery of the genetic code was a breakthrough of the first order. It showed why organisms are fundamentally different from any kind of nonliving material."
    Calling it a fundamental difference does not preclude it from being based on physics and chemistry.

    Descartes had difficulty explaining how res cogitans affects matter, suggesting that the rational soul operated through the pineal gland.Wayfarer
    The suggestion of the pineal gland was not an attempt at an explanation of how matter was affected, but rather a choice of something in/near the brain that there was only one of. Being somewhat symmetrical, most brain parts have a mirror part, but not that gland. Still, the soul could have been put in the heart (only one of those) or gut (plenty of behavior and choices come from there).

    What about abstract objects like numbers and logical rules? Do you think there are physical explanations for them?Wayfarer
    Abstractions are mental constructs, and so supervene on mental constructs/states. Same with abstractions of say an apple.


    We know that materialism fails since it cannot explain how ideas emerge and how they can be causally efficacious in the world, given that ideas are irreducible and have no parts.MoK
    1) I don't accept your given, and 2) as usual, your conclusion does not follow from your given premise.
  • On emergence and consciousness
    Not sure what you mean. What example of yours would I be countering?Patterner
    P1) Human consciousness does not supervene on physical processes.
    P2) Qualia is part of human consciousness
    C1) Human consciousness is a 2nd kind of property/substance that is not part of the physical processes described by physics
    P3) A human talks/writes about qualia, a physical action
    C2) Consciousness causes physical effects

    C1 encompasses varying kinds of dualism. I don't support this, so the example needs to come from those that do.
    C2 is a statement of interactionism. Descartes put the interaction in the pineal gland, supposedly because "I cannot find any part of the brain, except this, which is not double", whatever that means.
    I suspect that it was selected due to its inaccessibility (at the time) in a living subject.

    Chalmers seems to deny interactionism (I may have this wrong), but I could not find any explanation (except obfuscation) of how he gets around it. He has no counter-story. Either my logic above is not valid, or mental substances/properties have non-mental physical effects that are open to being measured.


    MoK has not replied to my identification of logic flaws in his OP, so I presume agreement.

    We are dealing with the strong emergence in the case of ideas since they are irreducible, yet they have a single content that can be experienced. Ideas are irreducible mental events since they can be experienced.MoK
    This is not consistent with your definition of strong emergence in the OP.
    I mean, your OP implies consciousness to not be strong emergence, and it too can be experienced. Emergence (weak at least, per your OP) means it is a function of the parts, not that it is experienced or not, nor if it is reducible.

    To be honest, I cannot figure out your stance, since weak emergence seems to be a conclusion of a physicalist, and yet you seem to support substance dualism.

    Experiencing a cup is a sort of weak emergence considering all the complexities between experiencing the cup and the cup. We, however, have the ability to experience ideas as well, which is a strong emergence.
    Experience of one thing is arguably weak emergence, but experience of a different thing is strong emergence? Really? All without any demonstration of the difference, or why these things cannot be emergent from different (non-human) parts with the same relevant properties.
  • I've been trying to improve my understanding of Relativity, this guy's videos have been helping
    Remember that Newton's laws apply to inertial frames only, and don't usually work in other kinds of frames. This also goes for most of the conservation laws.

    So what is the difference? Well in the inertia picture we are trying to give an answer to the age old question of Aristotle's prime mover argument. At least the childish mentality of it. If something moves something then something most move. . . or change. . . that thing. . . and so on.substantivalism
    This makes it sound like A causes B to accelerate (effect), which is wrong. Both interact with each other, with neither being cause nor effect. There is no regress.

    An infinite regress results unless we somehow end it in some fashion or make some object 'self-sufficient' in its motion without anything external. The point of the concept of inertia is to postulate just this. . . that an object can move or retain its properties without having something force it to do that externally.
    Motion under either model is an abstraction, a change in coordinate position over time, both of which are frame dependent. Thus velocity is not a physical property that gets mucked about by some other object. Contrast this with proper acceleration which is physical, and zero in gravitational inertial picture.

    This opens the door to 'natural' states of objects and 'un-natural' states of objects. Forced and un-forced. Following geodesics and not following geodesics.
    An object not tracing a geodesic is due to some force (EM say). So sure, using the term 'forced' seems weirdly applied, but appropriate. Calling it un-natural is deceptive.

    As for spacetime being a sort of aether/fabric, well, you described that pretty well, and contrast it gravity being a sort of material force rather than geomery. I don't see much difference between the views, just different ways of wording the same thing.


    It's like asking for the physical thing responsible for conservation of energy. . . energy is just conserved and we don't look further for the 'thing' responsible for it.
    Conservation is a property of laws with certain symmetries. Newtons laws of motion exhibit that symmetry. So yes, it isn't a physical thing that 'causes' conservation. We'd probably just not have a name for energy if it wasn't useful to reference.


    However, under the substantivalism picture we still desire to explain why things move the way they do and might feel at odds with bluntly just assuming the ways things move is just a law of nature not to be further explained by any other 'thing'. So we might choose to assert there is an entity who is responsible solely for grounding those familiar spatial/temporal intuitions of ours and explain why objects move the way they do.
    Entity-of-the-gaps can be done with any view, including the geometric one. It isn't an explanation, it's hand-waving away to the realm of magic that flies in the face of methodological naturalism, the lack of which kept science pretty much at a standstill for pretty much all of the dark ages.
    It makes for an even more complicated thing in need of explanation and as such, solves no problems.

    Slow reply, but primarily I am talking about mind interactionism here, which necessitates interaction between mind and physical (usually substances, but can be property dualism).
    Given this, the interaction point must be somewhere, and the tool used depends on where that point is.
    Even with panpsychism, all matter has mental properties that are not described by current naturalistic physics.

    So anticipating pushback on this, I tried to investigate non-interacting forms that still deny mental processes supervening physical, besides epiphenomenal views which refutes any talk about qualia and such. I could not find any, so my assertion above stands. A counterexample is required.


    You measure a physical change, how do you determine that it was fundamental consciousness that caused that rather than something else?flannel jesus
    You don't know of course, which is a good reason why physicalism is a valid position.


    I invite you to read the OP again.MoK
    I did and saw a long list of assumptions, most but not all of which I would accept. That's fine. What I'm pointing out is that the assumptions are not enough.

    Granting these assumptions means that there is a function that describes the property of the system.MoK
    This does not follow from the list of assumptions. It's an assertion. I'd not even disagree with the assertion except the part where you suggest that it follows from the list of assumptions.
    Sure, there's what you call a 'function' that describes a certain property of the system. That's just yet another assumption. It says nothing about if this property is emergent, strong or weak.

    The only avalaible properties are the properties of parts though.
    That also does not follow from the list of assumptions you provided.
    Therefore, the property of such a system is a function of the properties of the parts.
    That arguably would follow from the above statement, which unfortunately doesn't follow from the assumptions.

    Hence my question, "How do you know this"? How have you falsified the view that human experience is not emergent from the physical parts?

    Suppose I have a microchip (or series of microchips wired together) with x amount of switches. Are you saying that if I flip enough switches a certain way, consciousness will emerge?RogueAI
    I think you are talking about strong emergence here.MoK
    This seems very inconsistent. Why is one a function of the parts and the other is not a function of parts with nearly identical relevant properties?

    I like Patterner's example of air pressure being emergent from gas molecules, none of which has itself a property of pressure, at least not that kind of pressure.
    And yes, I also like @Pierre-Normand's emergence of chess from the movement of figurines, none of which are chess.


    I wasn't entirely sure what op meant by "a function of" in this context, so I (perhaps embarrassingly) asked ai:

    "In the context of the provided text, saying one thing is "a function of" another thing means that the property of a system can be mathematically or logically described and derived from the properties of its constituent parts [textual content]."
    That sounds like an epistemological definition. Something is an emergent property of the parts if we know how, and can derive (predict0 the emergent property. That seems to have nothing to do with if it actually is a function of the parts or if outside influence is required. The dualists have always leaned on such a definition. "I refuse to pay attention to advances in the field, so consciousness will forever not be a function of brain activity. They demonstrate always correlation, never causation.".
    flannel jesus
    I agree. But I don't think all properties are physical.Patterner
    That's another tack, suggesting properties of trivial parts (atoms say) that have never been measured by anything studying atoms.

    I don't think this is correct. I don't believe in strong emergence, but if there were strong emergence it would be casual - arguably more casual than weak emergence.flannel jesus
    Yes, it would be causal, and that makes for an empirical test for it.

    It is correct. If matter moves on its own, and experience is the result of how matter moves, then how could experience be causally efficacious?MoK
    Obviosly some physical change (a deliberate one) would have to lack a physical cause. The laws describing the states of matter would necessarily be incomplete.
  • I've been trying to improve my understanding of Relativity, this guy's videos have been helping
    In short, special relativity had to be derived as a consequence of Michelson Morley experiment as well as Maxwell's equations, and then General Relativity because he needed a way of keeping gravity fully local (in contrast to Newtonian gravity which involves instantaneous arrival of updated gravity information).flannel jesus
    M&M was pre-existing evidence, yes, and everybody knew a new theory was needed because of that. Several were working on it and Einstein put out SR shortly after LET, both valid explanations. Neither dealt with gravity and neither were geometric solutions.

    OK, keeping GR local was perhaps a major motivation for the geometric approach. Not sure how far Einstein would have got on his GR work had not Minkowski re-cast SR as a geometric model first, but that move was essential to the completion of GR.

    Also he had this idea - that was explained in the video - about how a guy falling wouldn't feel that he is falling. The "happiest thought in his life", right?
    Yes, the EP is based on that, that gravity and acceleration are locally indistinguishable, thus he could take the mathematics of accelerated frames from SR and derive things like gravitational time dilation. I think that part could have been done with the non-geometric model. Maybe. Not like I've worked through the derivations myself.
  • I've been trying to improve my understanding of Relativity, this guy's videos have been helping
    Nice explanation of how Einstein's spacetime curving explains gravitational motion as well as does Newton's force laws. What seems not explained is why Einstein's model is better, and where Newton's laws fail to make the correct prediction. What were Einstein's thought processes that made him move to this new model? The opening and title of the video ask 'why' and not 'how', so I thought this part would be covered.

    The only experimental evidence at the time was the anomalous precession of Mercury's orbit. That had to be it, but not mention of this I think in the video. Later, bending of light around large masses, and gravitational redshift were verifications, but neither of these had been done at time of GR publishing.

    This isn't an ad, I promise haha.flannel jesus
    But it has an ad built in that you have to wade through or forward past.
  • Does anybody really support mind-independent reality?
    There's a real problem about EPP. The root of the problem is the idea that something can exist before any predicates apply to it, or that something can have a predicate applied to it before it exists. Neither works. Hence "prior" cannot mean "temporally prior" so it needs to be reinterpreted or abandoned.Ludwig V
    First of all, 'prior' is their language, and it isn't a temporal reference. EPP says (without using that contentious word) that 'only existing things can have predicates', which is arguably self contradictory since a nonexistent thing would have no predicates, which is in itself a predicate. Meinong rejects that, so existence is not a requirement for predication.

    Part of the issue is that EPP isn't very specific about what definition of 'exists' is being referenced in its statement. Under def 1 (idealism), and 4 (deliberate assignment), predication seems prior to existence.
    Definition 3 (relational) also doesn't seem to require EPP. So that leaves 2 (part of the universe) and 5 (objective), the only ones that arguably need it, but if EPP is not assumed, I don't see any contradiction that follows from predication without existence.

    OK, def 2 as worded arguably of needs it because the universe needs to stand out from other universes, else it's just a universe. But since two objects can be a meter apart in one of the other universes, EPP isn't necessary for the predication, only for it being (unexplainably) preferred.

    So EPP fails at every step. You seem to find that problematic, but without begging EPP, you need to point out what contradiction results from it, being very specific about how you're defining your terms.

    Well, you're still left with the problems of idealism.
    As I said, under idealism, the elephant's existence is due to its being observed, being a phenomenon. That phenomenal relation results in the existence of the elephant, hence predication is prior to existence under idealism. You disagree I take it.

    I already knew that existence without predication makes no sense.
    If you define existence as 'standing out', yea, it can't stand out without predicates. Under idealism, that would mean existence despite not being perceived, which isn't really idealism then. 2-4 seem to require predication, yes. 5 (objective)? That one seems contradictory only because existence under def 5 is a property (not a relation), and a property is a predicate, as is the lack of the property.

    Thanks for your input Ludwig. Forcing me to work stuff out, which is good.

    My reply to you here belongs in my EPP topic.


    The question of mind independence that is of interest to me, is the sense in which the world exists independently of the mind.Wayfarer
    Just calling it 'the world' seems to be an assumption that this world is preferred, presumably because it is perceived. This sounds like a very mind dependent stance to me.


    Even if there is a counter-intuitive increase of number of 'bases'boundless
    Everett's thesis had to dumb-down the number of bases due to the finite but inexpressibly large actuality of the actual figure. For instance, you (a physical object with extension, at a moment in time) is undergoing trillions of splits such that there is no one measured state except relative to some measuring event well after said moment in time. Hence Rovelli saying that a thing cannot measure itself, it can only measure something sufficiently in the past to have collapsed into a coherent state. Not sure if it's Rovelli's term, but an extended system (a person say) at an extended moment in time, is a sort of extended spacetime event called a 'beable'.
  • Does anybody really support mind-independent reality?
    I mean sure, the elephant exists because its parents got busy one day, but that's not a fundamental cause. — noAxioms
    So what is more fundamental than that?
    Ludwig V
    The cause of its parents of course.
    I list what is probably classified by Aristotle as an efficient cause of the elephant. More fundamental would be a root cause, something realists need to face.

    Two pebbles are (at a particular moment in time) a meter apart. That's a relation ('is a meter from') even without them ever being observed or known. — noAxioms
    Oh, I see. The criterion you are applying is simply "being in a relation with something that exists".
    That would be a different relation than the one I listed. I mean, that's like 'being in a relation with something that's green', which begs the question 'what if it's a meter from something that's not green?'. It seems your relation asserts something in addition to the relation. Mine did not. That relation is a predicate, and if EPP is not accepted, only the relation 'is a meter from' is sufficient. Existence of neither object is required. With EPP, yea, they need to exist before they can be a meter apart.

    I can make some sort of sense to your acceptance of Meinong's rejection of EPP. I need to pay more attention to him, (thanks for that) but so far I can't make any sense at all of your being in the presence of elephant B.
    No different than the two things a meter apart. Existence of either thing is not required if EPP is rejected, so I can be in the presence of a nonexistent elephant. Since related things often (not always) seem to share ontology, I probably wouldn't exist either. My suggestion is that since elephant A & B are identical except for A existing, nether A nor B has any empirical test to see which is which. For this reason, I find existence defined as an objective property to be useless. Hence my not being a realist. All the problems of realism are solved.

    doesn't [Kant's] 'exist' boil down to 'I know about'? — noAxioms

    Not really. Phenomena are dependent on minds for their existence (and properties). But noumena are not.
    I really don't know Kant then. Those are not idealist ideas.



    I meant that the 'normal' basis is selected, after the measurement, due to the fact that our experimental apparatuses are structured in some ways. In other words, the reason why we observe things in the 'right' basis is that the the experimental apparatus has those properties it has. However, in principle, you could have that after the measurement the state vector 'collapses' to one of the vector in the 'wrong' basis.boundless
    I don't understand any of that. There is no right/wrong basis under MWI. They all share the same ontology, but some are more probable than others, whatever that means.
  • Does anybody really support mind-independent reality?
    Anyway, my contention is that if the interference terms are too significant, in the Schrodinger's cat experiment, the version of the observers that sees the 'alive' cat should perceive in some ways the other 'world'.boundless
    They are nowhere near sufficiently significant. I cannot think of a scenario, however trivial, where you'd see this. It would be the equivalent of measuring which slit the photon passed through, and still getting an interference patter. Interference comes from not knowing the state of the cat, ever.

    In my example of spins, for instance, we observe either '+1/2' or '-1/2', but we never observe the state 1/sqrt(2)('+1/2'+'-1/2').
    Sure we do. You observe that by not measuring the spin, same as not measuring which slit.
  • Does anybody really support mind-independent reality?
    As soon as you name a ‘world’ or a ‘thing’ or ‘an unknown object’ which you claim is unaffected by or separate from your thought of it, you are already bringing it within the ambit of thought.Wayfarer
    So much wrong with that sentence. Nit: I didn't name any particular world. I didn't have a particular one in mind, especially since it's quite difficult to do so. Secondly, I didn't claim anything, but I am defending the stance of those that claim a mind-independent reality. In such a stance, there is no 'ambit of thought'. That term presumes a very different stance. Under the mind-independent view, somebody thinking about X (X not being something in his causal reach) has zero effect on X, and in particular, has zero contribution to whatever the ontological state of X is.

    The realist always has something in mind when he or she speaks of ‘something unaffected by thought’.
    Arguably so, but being thought of doesn't change it to be affected by thought.
    We've switched to 'realist' now. I suppose most of those claiming mind independent existence of say some rock consider said rock to be real. Being real and existing are often synonyms, or treated as such, but there are pages keeping the two terms distinct.

    It’s a Chinese finger trap - you can’t even say it without undercutting the point.
    I haven't seen the point undercut, despite your implication of 'ambit'.

    [Einstein’s] critique was critical to the development of quantum theory. — noAxioms
    Yes, but the article acknowledges that.
    Wayfarer
    I know. I was relaying a couple snippets from the article since Einstein's realist leanings have been noted multiple times in this topic.

    Discover Magazine: In quantum mechanics an object can exist in many states at once, which sounds crazy.Wayfarer
    Only in some interpretations, and not crazy, just unintuitive.

    The equation should describe the world in a completely deterministic way, but it doesn’t.
    Schrödinger equation is deterministic actually. Penrose also seems to be a realist, which doesn't contradict QM, it just contradicts locality. Does he also disagree with say Bohmian mechanics?

    But what if physical reality is actually indeterminate on a fundamental level?
    There are those interpretations as well, such as objective collapse.

    Theoretical physicist Carlo Rovelli, founder of loop quantum gravity, has written seriously about how Nagarjuna’s philosophy of emptiness—the idea that phenomena lack intrinsic existence—resonates with quantum mechanics’ relational ontology, where particles and properties exist only through measurement relationships rather than independently.
    Preaching to choir


    MWI was developed before decoherence. MWI supporters like decoherence because it seems to explain the branching. It doesn't IIRC remove interference however.boundless
    Why would you want interference removed? It is seen. Even a realist interpretation like DBB has the photon going through one slit and not the other, yet interference patterns result. We experience that. Perhaps we're talking past each other.

    Yes, but there is a preferred basis in our experience.
    You don't know that, there being no evidence of it. Under MWI, there's no 'our', so every basis is experienced by whatever is entangled with that basis, with none preferred.


    It may well be special because it is observed. But observing something doesn’t normally cause it to exist. So even if it is special because it is observed, it may exist for some other reason. You need to demonstrate that there is no other reason.Ludwig V
    A realist might want to justify the existence of whatever he asserts to exist, but I don't count myself among them. I actually think its a big problem. I mean sure, the elephant exists because its parents got busy one day, but that's not a fundamental cause.

    If it doesn’t stand out to anything observing or caring about it, it’s not a relation.
    Nonsense. Two pebbles are (at a particular moment in time) a meter apart. That's a relation ('is a meter from') even without them ever being observed or known.

    I’m glad we agree on something. However, to establish the difference (or similarity) between A and B, you have to identify A and B. Suppose that A is the existing elephant. Your problem is that you have no non-existing elephant to take the place of B.Ludwig V
    Maybe I'm in the presence of elephant B and I've no relation to the existing A one. That would imply that I don't exist since such relations (in the presence of) tend to be between things with similar ontology.
    Given that statement, you may want to retract the 'agree on something', but if existence is a property, there's no way to know if you have it. It's usually assumed, but doing so renders the property meaningless.
    I did say I wasn't a realist. I usually define 'exists' as the original 'stands out to' relation, in which case yea, B exists to me and A does not. It's objective existence (a property) that is a realist stance, and it makes little sense to me.

    You might find a partial solution in Meinong’s workLudwig V
    My prior topic was on exactly that. I am more open to Meinong than most. My focus was on his rejection of existence being prior to predication (EPP). Given that rejection, I can be in the presence (a predicate) of elephant B without either of us existing.

    However, Kant argued that “exists” is not a predicate, which means that existence is not a property.
    I don't know Kant all that well, but doesn't his 'exist' boil down to 'I know about'? That is a predicate. Kant isn't exactly a ball of mind-independent opinions.
    To reject objective existence as a predicate is to embrace EPP.

    Some reservations. Your formulation has the consequence of limiting existence to things that have causal relationships with each other – that is, physical things.
    There's plenty of causal structures that are not typically classified as physical. Conway's Game of Life (GoL) is one example. A medium spaceship is an object in that structure. It moves (at 0.5c), can be created and have causal effects. It exists by this EP definition. But it lacks mass, energy, etc, words that are meaningful to our particular physics.

    Yes, Plato certainly used a different definition than EP. Plato cites the soul as something lacking in causal interaction? That seems contrary to how souls are often defined.

    One of many such apparent paradoxes in quantum physicsWayfarer
    PCD is not paradoxical, it just isn't classical.
  • Does anybody really support mind-independent reality?
    I meant something like 'QM without the reduction postulate'.boundless
    QM doesn't have a reduction postulate, but some of the interpretations do. Each seems to spin the role of measurement a different way.

    If you do not accept collapse, you still have superposition and interference.
    Yes, the latter two are, but the meaning of especially superposition is still interpretation dependent. Superposition itself is baked into the mathematics.

    So, you need to explain why we do percieve everything in a definite state.
    I suppose that explanation is interpretation dependent as well.

    But I was questioning if decoherence is enough for the appearance of collapse.
    It seems to be enough given an interpretation (MWI say) that explains it that way.

    Interference terms remain, they become however very, very small. Is that truly enough to explain our 'definite' experience (same goes for the cat's experience)?
    Interference is a statistical effect, so with no particle can interference be measured, let alone measured by the particle in question. But it can be concluded given hundreds of thousands of objects all being treated identically. So I suppose a really huge crowd of people (far more than billions) could collectively notice some kind of interference if they all did something identical. I cannot fathom what that experiment would look like or how any of those people could survive it.


    Basically, in MWI the branching is explained by saying that there is a superposition of definite states.
    Definite means something like this. Consider a spin 1/2 particle. When we measure the spin (say) in the z-axis we obtain either '+1/2' or '-1/2'. So, '+1/2' and '-1/2' are 'definite states'.boundless
    OK. They're post-measurement, so they are definite, sure, but post-measurement, they're not in superposition anymore, so it's only in superposition of definite state relative to a system that has not yet measured the lab doing the spin measurement.

    This is very well illustrated by the cat, where death when -1/2 is measured. From inside the box, there is one definite state and the cat is alive or dead depending on that. From outside the box, they know the measurement has been performed, but don't know the result of it. So the cat is in superposition of the interior definite state of being dead and alive, but the cat is not in a exterior definite state, meaning it is still in superposition relative to the lab. And yes, they can measure interference in principle.
    In practice, there's no way to keep the cat alive and in superposition since there's no way to prevent information from leaking out of the box.


    Here things go tricky, however. Why, when we make a measurement, does the quantum state collapse or appear to collapse in one state of the 'basis 1' instead of 'basis 2'?
    Interpretation dependent obviously. Some interpretations have no concept of 'our' experience since there's no 'you' that satisfies the laws of identity and non-contradiction. Keep that in mind.


    But if MWI-supporters do not want to make any reference to experience to explain how we have the quantum-classical transition, then why systems evolve as if they have to appear to collapse in a state of the 'basis 1', which happens to correspond to our experience?[/quote]MWI does not collapse in a state of the basis 1 which happens to correspond to our experience. It denies the bold parts at least. Basis 2 is also experienced, and as much by the pre-measurement 'you' as is the post-measurement 'you' that's in state 1, which is to say, not by the same person as the one before.

    This is a part of, as I understand it, the 'preferred basis problem'. MMI posits that 'basis 1' is selected by the mind.
    What is 'the mind' per MMI? It is some dualistic mind thing, sort of a moving spotlight which gets to pick which path it follows, with the other paths left as zombies? That sounds like uni-mind, so no, probably not that. You can tell I don't know much about MMI, especially the part about how they define 'mind'. Do trees similarly select their bases? Where do they draw the line between what has a 'mind' and what doesn't?


    Yeah, the paper is a bit technical and also beyond my paygrade. Basically, however, it tries to reject MWI by adducing that if a MWI supporter doesn't add some postulate to 'pure QM without the collapse postulate' you can't explain how the universe decompose in subsystems, how the preferred basis is selected etc.
    There's no preferred basis in MWI. That much I know. Can't speak for MMI.



    What thing would that be?Wayfarer
    We were discussing 'worlds', which is loosely referenced by the word 'thing' in my statement, despite not being an object. A world is unaffected by something elsewhere imagining one.

    Sure, but in a mind-independent view, you bringing it to mind has zero effect on the thing itself. It's ontology in particular is not a function of somebody's musings.


    So, I went through your OP carefully. I’m afraid that I do not come away with a general criterion for mind-independence.Ludwig V
    If you're looking for me to evangelize one, I tried not to.

    To say 'the universe exists' is actually to say 'this universe exists' and not the others. Why? Because we observe it."

    I’m not clear what this means.
    I am pointing out the distinction between 'a universe' (this being one of many) vs 'the universe', which implies there's just one, and we're looking at it. The preferred way things are has plot holes that I point out, and declaring only this one to exist is a mind-dependent act.

    For that statement, 'the universe' refers to all of our spacetime, even the parts not measurable, but not other type II universes such as ones with 4 spatial dimensions, just to name a simple difference.

    I'm harping mostly on 'the' vs 'a', and not so much on the problems with asserting that it exists.

    I'm harping mostly on 'the' vs 'a', and not so much on the problems with asserting that it exists.

    I don’t see any implications for mind-dependence or not.
    It out of gazillions of potential universes, only this preferred one exists, it is probably special because it is observed and the others are not. Sounds pretty observer dependent to me.

    The word 'exists' has its origins to mean 'stands out' which often implies that there is something to which it stands out.
    Yes! The origin of the word is a relation, and yet over time it gets thought of as a property. Elephants existing to me slowly becomes elephants existing period.
    That which stands out to an observer seems observer dependent. So I'm looking for a definition where yea, it stands out, but not necessarily to anything observing or caring about it. Still a relation though. Hence definition 3 (relational) of 'exists', which has nothing to do with perception or knowing about the related thing.


    For me, "exists" just means "There is/are.." as in "There is a moon" or "There are elephants".
    That sounds pretty objective. A thing either is or it isn't, a property that is true or false. But then how does an existing elephant differ from the nonexisting elephant, in any way that matters to it? That's a hard question since most dismiss the question before thinking about it.

    Well, it is true that if we perceive something, that something usually exists.
    Well, it stands out to us, so it exists as a relation. There doesn't seem to be a test for the existence as a property. That's the problem with the word slowly changing meaning from its original definition.


    The traditional example here is that a decoy duck is not a real duck
    Again, this topic is about ontology, not a completely different definition of the word that means genuine vs, counterfeit.

    "Principle 1 (The Eleatic Principle) An entity is to be counted as real if and only if it is capable of participating in causal processes" This wording of the principle is almost mind independent except for the 'counted as' part, and I've seen it worded without that.

    In principle, this is an interesting criterion, which could work, at least in standard scientific contexts. The original formulation in Plato’s Sophist) goes something like “Anything that exists is capable of affecting other things, and capable of being affected by other things.” But it works in favour of mind-independence of anything that it applies to. Your argument to adapt it to show the opposite is very weak, because you admit that there are different ways to formulate it. I;m afraid that in any case, phrases like “counted as” do not imply mind-dependence, at least as I understand it.
    Agree. I said that to show that it seems to be a valid mind-independent definition of existence, and an objective one this time, one that provides a test to pass or not.


    I would say that compulsion is when our deliberative power is coherced to act in a certain bway by internal (e.g. severe mental illnesses) or external constraints.boundless
    Say an epileptic fit.

    Bottom line for me: I don't think we have anything that qualifies as free will, and despite the positive sounding term, I wouldn't want it any more than I'd want a heaven where you can't be in pain. I all sounds good until you think about it.


    For instance, MWI supporters generally claim that decoherence is enought to have 'classicality'. But IIRC, interference isn't eliminated.boundless
    Of course not. That would violate theory. The moon exhibits classicality without requiring minds.
    Discussion elsewhere noted that if I enter ALDI double doors at high enough speed (multiple times), my cumulative demise will form an interference pattern on the far wall. The wall would have to be incredibly far away from the doors to notice it. They've not done it in the lab with anything larger than a bucky ball, but they have put eye-visible classical objects in superposition for really short times.

    I just think that the block universe takes things too far.
    Where I find it far simpler and elegant, and less filled with unanswerable implications such as what was the first cause.


    I take it as a suggestion that maybe you experience the consequences of interference constantly, as a matter of course, but they're just... normal. They don't look particularly different from anything else you experience.flannel jesus
    Yes, exactly

    Yet, QM taken literally tells us that we should perceive an interference of mutually exclusive states.boundless
    You'd have to show where QM says anything like that. QM does not contradict empirical experience.

    For instance both states of the cat in Schroedinger's (in)famous experiment.
    Right. There's no cat experiencing superposition or being both dead and alive. There's (from the lab PoV) a superposition of the cat experiencing living, and of experiencing dying by poison. A superposition of those two experiences is very different than the cat experiencing both outcomes. Each experience is utterly unaware of the other.

    Also there is the preferred basis problem. Basically, in MWI the branching is explained by saying that there is a superposition of definite states.
    'Definite states' sounds awfully classical to me. MWI is not a counterfactual interpretation, so is seems wrong to talk about such things.

    See on this this paper: "Nothing happens in the Universe of the Everett Interpretation" by physicist J. Schwindt.boundless
    Hard to read, lacking the background required, but it seems to say that there are no 'worlds' from any objective description of say the universal wave function. It has no 'system states', something with which I agree. There are no discreet worlds, which again, sounds like a counterfactual. I think the paper is arguing against not so much the original Everett paper, but against the DeWitt interpretation that dubbed the term 'worlds' and MWI and such. I could be wrong.
  • Does anybody really support mind-independent reality?
    The world 'in itself' is formless and therefore meaningless.Wayfarer
    It's still a world. Nothing names it that, lacking information processing to give meaning, but that property (worldness) seems to be an example a feature of the thing in itself.

    We mistake the form discovered by the mind as something that is there anyway, not seeing that the mind is the source of it. Kant 101, as I understand him.
    I agree that form interpreted (not discovered) by mind is often mistaken thus.

    Interestingly, there is the 'many-mind' interpretation (MMI). In this view, the physical universe evolves in the same way as is described by MWI. In MMI, however, the 'emergence' of a classical universe is, in fact, due to 'mind'. That is, the definite outcomes in which the wavefunction 'splits' are observed by different minds.boundless
    I never got that interpretation since it being different definite outcomes is relative to anything, not just information processors. I suppose I'd need to delve into it more to critique it more informatively.


    If unicorn-like creatures exist anywhere in the universe, their similarity to the unicorns we know and love is entirely coincidental and proves nothing.Ludwig V
    What would you want to prove? How does your assessment differ from anything else that's in the universe but unobserved? Whether or not humans would classify/name it as a unicorn or not has no bearing on it being there.

    That pattern of argument can be used to prove the existence of anything that you can imagine.
    Then imagine something more exotic like that 4-spatial dimension 'rock'. That can't exist in the universe, but is hardly impossible in another. That thing can't exist if 'the universe' is the only privileged one. So how does our chosen policy deal with that?

    [/quote] In which case, you'll have to ask someone else.[/quote]You abstain, which is much what the topic title is about. Few hold a consistent enough view to deal with these outlier cases. What I see exists. What I don't, well, I don't care. That sounds awfully observer dependent even if you assert that it would exist without people to see it. Too late. It's already been observed. Can't unsee it by pretending we were never there.

    You have what, to me, is a very peculiar idea of what the universe is.
    No actually. I can think of half a dozen definitions, but 'everything that exists' makes 'existence' definition 2 circular. You don't know if we're part of that set, and thus if we exist.

    I tend to put 'universe' as 'all that came from our big bang', but even that is ambiguous. It at least allows one to posit more, and make words like 'multiverse' meaningful, which it isn't if 'universe' is all that exists.

    I do put the moon and the thermostat in the universe.
    Why? I know, it sounds like a stupid question, but given your fairly objective definition, how specifically do you justify that statement? I use a different definition, and yea, would put the moon and theormostat in my 'world', which is confined to my past light cone. I relate to the things in my world, and those things exist (def 3) relative to me, but not in any objective sense. That definition is nicely mind independent, but you may differ.

    I'm less sure about unicorns. They are mythical creatures
    Not talking about the myth or the concept, but actual unicorns. Keep that in mind. Sure, the myth exists, in stories. Not what's being asked.

    You may be suffering from delusions of grandeur.
    Here I thought I was humble by being quite unsure of even my own existence (by any definition).

    But it does seem fairly well established that making observations at quantum level does have a causal impact on what happens
    Not true. Most realist interpretations deny any causal impact from observation. No wavefunction collapse. The transactional interpretation seems to be an exception to that statement, but I know little about it.


    Well, unless you can show me a mathematical model that can predict (deterministically or not) choicesboundless
    Inability to express something complex as a function of trivial operations doesn't mean that it isn't a function of trivial operations, but of course it also isn't proof that it is such.

    Interestingly, I made a similar objection to the 'block universe', where all events past, present and future have the same ontological status. If we can be so wrong in our experience, how can empirical knowledge (which is needed to falsify/verify scientific theories) be trusted?
    Empirical knowledge is exactly how we correct our initial guesses, which are often based on intuition.

    I think that it depends on how one understands morality.
    Yes, quite. I understand it as a contract (written or not) with a society. Many would define it differently. My assertion about the isolated person works with my definition, and not with some others.

    Determinism shouldn't be confused with compulsion as it often is in these discussions. — noAxioms
    How so?
    Compulsion is when you make one choice, but are incapable of enacting it. Cumpulsion is not the inability to do two different things, which is what 'could have done otherwise' boils down to.



    Its irrelevant why I believe something does not exist.Philosophim
    Then this topic is not for you since it is all about the limits of what we feel exists, and what doesn't meet that criteria.
    Its relevant if I know that something doesn't exist.
    Nope. This topic is not an epistemic one. I'm not asking how you know something exists or not. I am looking for a belief system that is consistent with mind independence, and where the limits are placed is critical to that.

    Knowledge is an objective determination.
    Subjective actually, almost all of it anyway. I doubt you'd figure out 2+2=4 without subjective input, even if it is arguably objective knowledge.

    The only way to know if a belief is valid is if you have done the diligence to turn it into knowledge.
    No, that's how you know the belief is sound. What I'm talking about cannot be knowledge, so logic must be used to validate it. Nobody seems particularly inclined to expose their own beliefs to this analysis.


    Self consistent, and oftentimes with low correspondence to reality.wonderer1

  • Does anybody really support mind-independent reality?
    Bell didn’t prove anything.Wayfarer
    This is the part I missed all this time, that the proof structure was there to prove that quantum theory is correct if these experiments could be verified, but the experimental backing was not yet there. Thank you so much for this. It will help prevent me from spouting further nonsense about this subject.

    Apparently there was a laundry list of things to verify, which began in the 70's and was completed by the guys winning the prize 3 years ago.


    Realism neglects the role of the mind in this process. — Wayfarer
    Yes. If that sort of mind plays a role, it makes its own predictions, different than the ones made by quantum theory.

    Realism already necessarily rejects locality, which allows action from outside, but even nonlocal QM allows nonlocal information transfer, and mind playing a role requires that, no?

    - - - - -

    Do you think there was a mind involved that created the electricity? Do you think that if your power was out, you could walk over to your computer, type a message, and it would appear on the internet?Philosophim
    You've apparently not read much of the thread. Not suggesting any of that. Not even the idealists suggest that.

    Pick something you believe doesn't exist. Why do you believe it doesn't exist? What is your criteria for deciding one way or the other? I ask because the criteria specified is most often based on observation, making it observer dependent.

    There is often a confusion between "What we know" and "What is".
    Almost everything is 'what we believe'. Much of what claim to be known is just beliefs. I'm fine with that. I'm not asking if we know reality is mind dependent. I'm seeing if the beliefs are really what they claim to be.

    What we know is clear: There is a world independent of our own minds.
    That is a fantastic example of a belief. Plenty of self-consistent views deny this. I personally would say that a world external to myself is perceived. That much makes it relation with an observer. It does not imply that said world exists, unless 'exist' is defined as that relation (which is often how I use the word).


    The mind or brain integrates all of that data with our remembered world-model to construct a panoramic vision we know as 'the world' (panorama literally meaning 'seeing all'). Without that conscious and unconscious process of data reception and synthesis, there would be no world to see.Wayfarer
    I think the realist position (and not just the direct realist position) is that there would still be the world (quantum definition of the word), relative to something measuring it (a rock say), but yea, all that synthesis that the human mind does is absent, so it would be far more 'the world in itself' and not as we think of it. Time for instance would not be something that flows. Rocks have no need to create that fabrication.

    I chose rock and not apple because an apple is definitely a product of perception. The think would not exist without perception since it's design/purpose is to be perceived.

    It's not something infants see; they have to learn how to see it, an act which takes the first few years of life.
    Most of it seems learned by the time the baby is perhaps hours old. They've done experiments with say depth perception and aversion to heights, to newborns opening eyes for the first time. Plenty is built in an not just learned.

    I can think of an alternative [to determinism/randomness] but I can't formulate it mathematically and I can't think of how to make a scientific test that can be used to falsify the idea.boundless
    Tell me. It not being mathematical is also great because it challenges something like MUH. And there's no falsification test for the random/determined issue either.

    If emprical data can't be trusted, what even is the point to do science?
    Which is why BiV, superdeterminism, and say Boltzmann Brains all need to be kept in mind, but are not in any way theories, lacking any evidence whatsoever.


    We generally do not held accountable people if they could not act otherwiseboundless
    So some societies operate, but such societies are quite capable of rendering such judgement using deterministic methods. And yes, I think morals are relative to a specific society. A person by himself cannot be immoral except perhaps to his own arbitrary standards.

    But if one that dies of starvation didn't have the possibility to act otherwise can we held that person accountable?
    I don't hold the person accountable, nature does. One has an obligation to not starve. Death is the unavoidable punishment, and only that death potential make eating an obligation and not just one more choice.

    An you do have the opportunity to act otherwise. Brains were evolved to make better choices, which wouldn't work at all if there were to choices available. Determinism shouldn't be confused with compulsion as it often is in these discussions.

    If you think determinism has any relevance to accountability, how is any alternative (randomness say)
    any better? I cannot think of a moral choice where randomness would yield a better selection.
    I don't think there's any relevance at all, so the question is moot to me.



    A general rule would be good. But how can one work that out without looking at specific cases? Rule first is just wild guessing.Ludwig V
    It isn't wild guessing since the rule needs to be consistent with what we do observe, and the opinions of most people don't meet that criteria, per the OP.

    The unicorn, as a specific case, should of course be 'I don't know'. So an educated estimate might be in order, which is not wild guess. How about a 4 dimensional rock? That's not going to be part of 'the universe', so either you pick a rule that says it doesn't exist, or pick one that doesn't confine existence to 'the universe', or perhaps, 'the universe now'. Once we have a rule, we analyze it for mind dependence, and per my argument, anything that mentions 'the universe' is probably going to be mind dependent, unless one defines universe far more broadly with 'all that exists', in which case one is left wondering if we're part of that. I am at least. Most use a definition that includes one's self.

    I would have probably classified moon, unicorn, and thermostat in the same category of either 2: Part of this universe, or 3, relational. — noAxioms

    I don't understand how 2 or 3 applies to all three and I don't see how that classification tells me anything about their mind-indendence.
    2 is 'part of the universe'. You probably put the moon and thermostat in the universe. I consider the universe to be sufficiently large to leave little probability of the absence of a unicorn anywhere. Hence same classification. 3 is trickier since it needs to relate to me, so perhaps the unicorn isn't close enough to do that.

    As for mind-dependence, we call our universe 'the universe', making it privileged because we see it. That makes it a pretty observer dependent definition of existence. 3 is not observer dependent, but depends on causal relationships. Existence is thus only meaningful within structures that have them.

    That's not quite what I meant. I have no idea what spacetime would look like and even less idea what a picture of spacetime would look like.
    Internet is full of them. OK, so you don't have a physics background. Makes it harder to discuss relativity and quantum implications to this topic.






    It only becomes a contradiction if you claim the existence of misunderstanding, and also claim the lack of existence of anything. — noAxioms

    Which is precisely what you did, on both counts, affirming the LNC violation you asked for.
    Mww
    You'll have to point out where I did any such thing.
  • Does anybody really support mind-independent reality?
    But I said 'share the same ontology' without saying what that ontology is. I also somewhat misspoke, since a presentist would say the moon 'is' while the Theia event (where the moon is created) 'was', a different ontology. — noAxioms

    Are you also saying that there is no connection between those two facts?
    Ludwig V
    No, I'm not also saying that.

    I don't see that things that don't exist are relevant here. Mind-independence doesn't apply to them.
    It absolutely does apply. The justification given for its nonexistence gates whether the chosen stance is valid or not. It's the core point of this whole topic.

    What if there cannot be a single model that applies to both unicorns and the moon?
    Then you don't have a valid model, let alone several of them. A quite simple model might say that both exist, the unicorns just being somewhere else where we don't see them. That example shows that there can be a single model that applies to both. Another is that unicorns don't exist, but moon does. That's likely more popular, but it isn't specified why the model declares unicorns to be nonexistent, so it's incomplete.

    How could we possibly know about things that exist independently of our minds without observation?
    I've never required us to know about them. This is a model, not proof of existence or not. The topic is not about epistemology. We can't know if the unicorns exist or not, and we certainly can't know if our chosen model is sound or not, but we can at least come up with a valid one.

    I don't see why you would think that what I would say about the existence of unicorns can be generalized to everything that exists.
    You got it backwards. The general rule is what I'm after. The unicorns end up on one side or the other depending on the rule chosen. Rule first, then assessment of unicorn or whatever. Point is, I want a rule that you might assert belief in, and one that has the property of mind-independent existence. If you can't do that, then my title is pretty accurate: Nobody really believes in mind-independent existence. They might assert it, but they apparently don't have a coherent model that supports it.

    What existence means depends on the kind of object your are talking about. So there is one criterion for the moon existing and a different one for unicorns existing; the criteria for thermostats are different again. The criteria for existence are truth-conditions, so are not themselves true or false.
    OK. Sounds like the beginnings of a complex model. I would have probably classified moon, unicorn, and thermostat in the same category of either 2: Part of this universe, or 3, relational.

    I'm a bit puzzled about what you mean by "the picture" here.
    You compared my suggestion of a spacetime diagram to a picture of the same subject, presumably from some point of view.


    Before early 20th century it seemed uncontroversial that everything is deterministic.boundless
    Classical (Newtonian) physics is not deterministic, and if they thought so 1.2 centuries ago, they didn't think it through. Norton's dome is a wonderful example, but that was published only a couple decades ago.

    Why do we have to be so certain that, in the future, we will find out that physical laws allow that some events are neither probabilistic nor deterministic?
    We're not so certain, but can you even think of an alternative? One alternative is that the system isn't closed, but non-closed systems have always failed to be either deterministic or random.


    According to superdeterminism, there are correlations that 'trick us' in believing that either 'realism' (CFD) or 'locality' is wrong. But superdeterminists argue they are mere coincidences.
    Yes. Empirical data cannot be trusted, and that's why it's not an interpretation of evidence, but rather a denial of it, similar to BiV. Yes, superdeterminism can be locally real. It's a loophole. Still is even under the new improved 'proof' 3 years ago.

    If all my actions are deterministic, it is quite controversial to attribute to myself moral responsibility.boundless
    That's the line, yes, and its a crock. FW is only needed for moral responsibility to something not part of the deterministic structure, such as an objective moral code. But I've seen only human social rules, hardly objective at all.
    The alternatives are randomness and not-closed system. The former doesn't yield external moral responsibility either (as you point out), so the latter is required, in which case the system is simply larger, and we're back to determinism or randomness again.

    After all, I literally could not have behaved otherwise.
    That does not absolve you of responsibility (to something within the closed system) for your choice. This has been fact for billions of years. You are responsible to eat. Punishment is death. Nothing unfair about that.

    To make sense of moral responsibility, you need to impute to moral agents some deliberative power and a sense of right and wrong.
    All correct. All those are best implemented with deterministic mechanisms.

    Cognitive dissonance is quite a risk.
    I get along with it fine.

    Would you consider moths as moral agents?
    Not much. They're not particularly social. My point was that moths find utility in, if not randomness, at least unpredictbility. Utilization of randomness has nothing to do with morals.


    My, but we're digressing, no?


    The model I had in mind is described in this paper: "Reality and the Role of the Wavefunction in Quantum Theory" by Sheldon Goldstein and Nino Zanghì. It is an interpretation of the de Broglie-Bohm interpretation (dBB) where there is no mention of a quantum potential that 'guides' the particles in a non-local way as Bohm and Hiley believedboundless
    Said 'guide' sounds like pilot waves, something definitely associated with dBB. The variant doesn't go along these lines then.

    Anyway, according to the variant in the linked paper, the wavefunction should be thought as a 'law of motion', a sort of kinematic law that, however, is explicitly nonlocal.
    I don't know enough about QM to comment about wave functions being anything but nonlocal. I mean, they're supposed to describe a system, or at least what's known about a system. The latter suggests that the real wave function is different than the one we measure. It being a system means that it's nonlocal since systems are not all in one place. That it sort of describes a state implies a state at a moment in time, but a nonlocal moment in time is not really defined sans frame. So we really need a unified theory to speak the same language about both theories.



    It was the 2022 Nobel Prize in Physics which was awarded to the experimentalists who proved it. (I wrote an article on it for anyone interested).Wayfarer
    So what didn't Bell prove 55 years prior? From reading up on the prize, it was for vastly improved techniques and closing several (but not all) holes.


    and yet, in order to not understand what I said, what I said necessarily must have been something that appeared to your senses. Hence, the LNC….which follows from the quoted absurdity on the bottom of pg17….you can’t claim to misunderstand something that wasn’t there.Mww
    This makes no sense. If there wasn't anything, there'd be no misunderstanding, no existing claim of anything. That isn't a contradiction.
    It only becomes a contradiction if you claim the existence of misunderstanding, and also claim the lack of existence of anything.

    Hence there seems to be no necessary existence of anything.
  • Does anybody really support mind-independent reality?
    The question you should be asking is: why is the apple intelligible?boundless
    Does asking that help nail down a mind-independent reality? Perhaps the answer to that question does.

    Assuming that such a probabilism is 'real', why can't we think that there are other possibilities besides determinism and probabilism?
    Maybe there are, but they'd still have to conform to the theory.

    In a sense, yes. But I would not even call newtonian mechanics 'wrong' tout court. Our physical theories give us incredibly precise predictions. They have to be at least partially right.
    Newton is not wrong, and it is all still taught in schools. But it is a simplification, and requires more exactness at larger scales.

    YMMV.
    What does the rest of the world say? How does that acronym convert to metric?



    I just find bizzarre that a 'scientific realist' would prefer to say that there are 'unexplained nonlocal correlations' than saying that, perhaps, instead there are nonlocal interactions of some sorts.boundless
    Unsure of the difference. A local interpretation asserts neither nonlocal correlation nor interaction.

    If we renounce to find an 'explanation' of those correlations, why not simply take an epistemic interpretation of QM?
    Isn't that kind of what Copenhagen does?

    Also, despite saying what I said, I also recognize that perhaps we are less free than we naively think we are.
    Well, plenty of folks want to assert free will because it sounds like a good thing to have, and apparently it is a requirement for some religions to work, which makes it their problem, not mine. If I'm designing a general device to make the best choices, giving it free will would probably be a bad thing to do. Imagine trying to cross the street.

    How about a moth? Moths fly about in unpredictable ways, making them harder to catch, and thus more fit. That's a benefit over deterministic (or at least predictable) behavior. Maybe moths are the ones with free will.


    If the two marbles, however, are in some way 'nonlocally entangled'boundless
    What does that mean? I only know 'entangled'. Is there a difference between locally entangled and nonlocally? Anyway, I presume the marbles to be entangled, in superposition of blue/red. You'll measure one of each, but until then, they're not any particular color. The marbles are far apart.

    you can't treat them as two separate objects but perhaps as two parts of an undivided whole. In fact, what is common between, say, most readings of de Broglie-Bohm interpretation* and Neumaier's thermal interpretation is that entangled systems do form an undivided wholeness. Perhaps this also means that two different 'objects' can occupy the same position (or limited region of space).
    Well, my only comment here is that this sounds a lot like your prior quote about time being entanglement, and space as well, all this being a sort of solution to the different ways relativity and QM treat time.

    For that reading it 'just happens' that particles follow a nonlocal law of motion.
    I just picked this bit out. What is a nonlocal law of motion? Example?

    I do appreciate links since you've already sent me down several new pages I've not heard of before. Always good to read new things.


    But my view is that 'being rational' is a full realization of our own nature.boundless
    Dangerous. I don't think you'd be fit if you had that realization. Part of it would be the realization of the lack of need to be fit.


    Well, I don't understand how it isn't violated except if both values actualize, i.e. a MWI-like scenario (not of the modified type I imagined before)
    Which is why I said 'only one value', because yes, otherwise it's something like MWI, which is back to full determinism, and you wanted an example of block randomness.

    That's a description of how it was created and already assumes the moon shares the same ontology as those solar system events long ago. — noAxioms

    Well, yes. It is an object in the solar system, so it seems a reasonable assumption. Any question about that is pretty much incomprehensible to me.
    Ludwig V
    But I said 'share the same ontology' without saying what that ontology is. I also somewhat misspoke, since a presentist would say the moon 'is' while the Theia event (where the moon is created) 'was', a different ontology.

    I get a bit confused by "mind-indendent reality", which, pretty clearly is about existence.
    OK, so pick something that doesn't exist, and justify that. Or pick something that exists outside of experience, and justify that. That's what I'm looking for in this topic: Somebody who can come up with a consistent model of mind-independent existence. But when pressed, it seems that everybody's limits of what exists or doesn't relies on things gleaned through observation.

    You did cite unicorns in your earlier post. It is true that my disbelief in them is defeasible. (Most claims about non-existence are.) But your argument is wildly speculative and does not even begin to convince me.
    You're missing the point. The speculative argument is about the odds of them existing in this universe, which is only relevant if only things in our universe exist. If that's the case, it is the preferred universe because it's observed, no? I'm not trying to-argue that unicorns exist (or don't). I'm trying to argue that your notion of what exists is a mind-dependent one.


    But I would insist on the truth value.
    Definition 4 totally discards truth value. 2 can have a truth value even if it's a relative truth. 2 boils down to [is a member of a preferred set, and members of other sets don't matter].


    A recent Nobel prize in physics was given for proving this again, despite Bell doing it in the 60's. — noAxioms

    That's odd. There must be a story about that.
    Ludwig V
    The recent prize was given for apparently proving things to more precision, developing new techniques for taking such measurements. Good stuff, but the pop articles make it sound like it wasn't already known. Bell's theorem (and not just 'theory') demonstrated the impossibility of local reality almost 60 years ago.

    I'll venture on one ignorant comment. If you try to define space and time or space-time without any physical objects, you are bound to run in to trouble.
    Seems mathematically valid, but meaningless, much like a blank graph of X-Y axes needn't bother with numbering the tick marks on the axes.

    At least, it seems obvious to me that those dimensions only have meaning in a universe that includes some actual objects. But then, so far as I can see, a space-time diagram is a method for plotting physical objects, like a map, rather than a description of reality, like a picture.
    Funny then that I find the picture less like reality and more like an abstract interpretation.


    What if Y doesn't happen in the future? An uncountable number of things had been "sure bets" never happened. How can Y be real in the sense that either X or Z are real?Patterner
    The block interpretation answers that one at least. There are versions of presentism that say that Y (in the future) exists as fact. You're 'sure bets' are not fact, but merely predictions made without access to the full history. So yea, you could have a block universe, but with a preferred moment in time. This is the 'moving spotlight' view and it even permits some of the nondeterministic interpretations.


    What’s violated, absent the something that necessarily is…the LNC and the principle of cause/effect.Mww
    I don't see how the lack of anything violates any of those laws, or why those laws (especially the cause/effect law which isn't relevant at all outside a causal structure) apply to this non-state. Also, it seems that the reality of our universe is violated by your causal law there since it needs something to have caused it.


    Reality is not real; things that appear to the senses are real
    Pretty much an idealistic statement, and I don't need idealists defending the realist view, as this topic asks.
  • Does anybody really support mind-independent reality?
    If I believe that the moon is exists independently of what I, or anyone else, thinks about it, is that an ontological claim? If so, the mere fact that we categorize or classify something in some way, in my view, is no ground for claiming that it is mind-dependent, though the classification obviously is.Ludwig V
    Yes, that's an ontological claim, and of mind-independence. That part is easy, and quite common. The challenge is with where it ends. Pick something that exists despite lack of evidence, or something that doesn't exist, with justification of why not. It need not be something known obviously. So it's an opinion. My topic is about if your opinion is self-consistent, because few think about it further than opinions about what is seen. This is why the moon doesn't matter.


    I would not dream of claiming that the moon is real because of empirical evidence, because that is not true.
    Poorly worded on my part. Typical claim is that "I know the moon exists due to empirical evidence". It's an epistemic claim about ontology, but not directly an ontic claim.

    The moon exists because of complex events in the solar system, some billions of years ago.
    That's a description of how it was created and already assumes the moon shares the same ontology as those solar system events long ago.

    We can agree that your birds do not exist.
    Why should I agree with that? The bird example was admittedly a reach for impossibility/improbability, but a helicopter gets close to fitting the description.

    But, since you have imagined them, they are imaginary birds and consequently not real birds, and not real.
    Imagining something presumably isn't what makes it not real. Again, I'm not talking about the concept of something, but about the thing itself. I have a imagined image of the moon, what it's like up there, which doesn't make the moon nonexistent.

    As to the distinction between "exists" and "is real", I had assumed that anything that exists is real.
    Contradicting your prior quote: "For me, unicorns exist, all right. But they are not real creatures.".

    A forged banknote is not a real banknote, but it is a real forgery.Ludwig V
    Different definition of 'real' there. We're discussing ontology, not 'being genuine'.
    I've seen whole topics devoted to the latter: "My signature is not mine since it was made by a pen, not by me". Games like that.


    The difference is that there is no classification under which I can say that a unicorn exists. That's a difference in meaning between "forged" and "mythical".
    To be a unicorn, all it needs to be sort of horsey-like with a single horn on its head. There's no requirement to correspond exactly to the human myth (attracted to female virgins, blows rainbows out of its butt). A Rhino is almost one, similar to how manatees were sometimes taken for mermaids. Still, not particularly horsey. I don't like the unicorn example because it is so improbably that there is not a planet in the infinite universe somewhere that has produced them. And that's a mind-dependent opinion because I reference 'the universe', making it preferred due to us being in it. I mean, Tegmark calculated how far away is an exact copy of Earth (given a classical universe). If that's there, there's plenty of unicorns between us and it.

    So again, just because there's a myth about it, why does that preclude the reality of one? It's like you're saying that the myth causes its noexistence.


    I must confess that I don't have a firm view of about presentism and eternalism. We seem to have a difference in our understand of "exist".Ludwig V
    There are many definitions, rarely clarified when the word is used. Some examples:
    1) Idealistic: A thing exists if it is conceived. Not particularly mind independent.
    2) Part of this universe: The universe is what is real, as is its contents, observed or not.
    2p) Part of this universe now. There is a preferred moment in time, and only the current state of the universe is real. The rest is not.
    2e) Time is part of the universe, so all states/events share the same ontology.
    3) Relational: X exists relative to Y if Y has been affected by X. This is seemingly relevant only in causal structures.
    4) Existence is whatever we designate as such, an opinion which doesn't have a truth value.
    5) Objective: Existing (or being real) is a property of some 'things' and not a property of others. It is unclear how to determine this property, but two interacting things probably have the same ontology as each other.

    There are other definitions, but that's a taste. Your intuitions seem to lean heavily towards 2p. I favor the relational definition most often since it is far more compatible with quantum mechanics. I've been exploring the 4th one.
    The 5th one allows (but does not require) other universes to exist, ones that are far simpler, or ones with 4 spatial and 2 time dimensions and stuff like that. I find #5 empty since the property doesn't seem to be required for anything. My prior topic was all about just that.

    Reality is an interpretation of empirical data.
    I want to say this is a mind-dependent definition, but it might be too hasty. The apple exists not because it is observed, but its observation suggests an interpretation of reality that includes that apple. Fair enough, but it doesn't say how the interpretation deals with things not observed, and this topic is mostly about that.



    Could you please enlighten me - What is "local realism"?Ludwig V
    A recent Nobel prize in physics was given for proving this again, despite Bell doing it in the 60's.

    'Local' refers to the principle of locality, that information, cause/effect, cannot go faster than light. 'Spooky action at a distance' suggests otherwise, that measurement of one of a pair of entangled particles instantly (whatever that means, given relativity of simultaneity) affecting the state of the other, no matter how distant. Whether this actually occurs has never been verified, so there are local interpretations of QM such as Copenhagen, RQM, MWI, Qbism.

    'realism' in this context refers to the principle of counterfactual definiteness which states that a system is in a given state even in the absence of measurement. So for instance, a photon exists in space en-route before it finally hits something. It has a location and momentum and such. It factually goes through one slit or the other despite nobody measuring/knowing which one.
    Realist interpretations include Bohmian Mechanics and Transactional interpretation. These all require faster than light cause-effect.

    Proving that reality is not locally real means that at most one of the two above principles is true.
    An example that rejects both principles is objective collapse interpretations.


    This is all quite relevant to the topic, because under most interpretations, the moon is not objectively real, but only real to that which as measured it, which usually means anything that has in any way interacted with it by say receiving a photon emitted by the moon.




    Can we really think about things that are outside our 'experience'? Read what philosopher Michel Bitbol said:

    As soon as you think about something that is independent of thought, this something is no longer independent of thought!
    boundless
    Sure, but I'm not asking about something not thought of. I'm asking about something that doesn't require that thought for its existence.

    The natural conclusion of this little thought experiment is that there is nothing completely independent of experience. — Bitobt
    Totally doesn't follow from what he writes. Not impressed. All that follows is that nothing thought of goes un-thought of, a trivial tautology.

    If we answer to this that, indeed, we can know something 'mind-independent' we have to assume that what is 'mind-independent' is conveniently intelligible, at least in part.boundless
    I cannot agree. 1) An apple is typically presented as mind-independent, but it is intelligible. 2) (Caution: new word coming) The thing in question could be entirely intelligible, but lacking anything in any way experiencing, imagining, or knowing about it, it merely fails to go itelligiblated.


    Ok, I see. What about a dual-aspect view though? If the mental and the physical arise both from math, perhaps neither mind nor the physical has a precedence.
    You mean independently, one not supervening on the other? Yea, then there'd be no precedence between those two.

    It seems that you assume here that the only possible alternative are either determinism or probabilism.
    Those seem to be the only valid alternative in QM. Even the consiousness-causes-collapse interpretation doesn't have mind doing anything deliberately. There's not control to it. All the interpretations exhibit phenomenal randomness.

    But what if our knowledge of 'the world' is limited and, in fact, the regularities of nature make room from something else?
    Then we're wrong, being insufficiently informed.


    Superdeterminism is supposed to be local — noAxioms

    Yeah, but ironically even it needs the existence of wildly nonlocal unexplained correlations that some how 'trick us' in believing that 'local realism' is false. One might, however, ask the superdeterminist how these correlations were there in the first place.
    boundless
    Those correlations might be widely separated, but never is there superluminal cause-effect. Thus is is considered a local thing, but not an interpretation.


    Here I use relationism to defend presentism. Since there is no 'view from nowhere', when I jump into a black hole for me time stops.
    No it doesn't. Time is experienced normally for all observers in both views. Under presentism, you simply abruptly cease to exist at the event horizon. The experience under eternalism is of being inside, also with time phenomenally flowing as normal.

    So a global presentism is certainly refuted, but perhaps a local one?
    I don't know what these are, and absent me jumping into a black hole, I've not refuted anything.

    But from our experience of change, we get the a very convincing impression that the present alone is real and the future and the past aren't.
    That's the impression, yes. Doesn't make the impression correct, especially since both interpretation give that same impression.


    Also, I should add, however, that in a deeper sense, perhaps, nothing is 'mind independent'. As I mentioned before, I lean towards some of forms of 'ontological idealism' and theism, some forms of mind as fundamental. But such a 'mind' is not our own.
    Maybe you're not the person to ask then, as I'm also not.


    Well, for instance, I have the 'impression' that my actions are neither deterministic nor probabilistic.boundless
    We all have that impression, but as said, I give little weight to that evidence. I find my actions deterministic in the short run, but very probabilistic as the initial state is moved further away. So sure, given a deer crossing in front of my car, my reaction would likely be the same every time. On a longer scale, it is not determined in the year 1950 that i will choose vanilla today since it isn't even determined that i will exist. Under MWI for instance, fully deterministic, I both choose and don't choose vanilla, but under the same MWI, almost all branches (from one second ago) have me swerving (nearly) identically for the deer.


    So, I consider that immediate impression as evidence that, perhaps, there is something other than determinism or probabilism. Prove me wrong.
    There is dualism, which is something other. But immediate impression isn't good evidence for that one since the determinism and probabilism both also yield that same impression.


    Well, right, but if the universe is not infinite, then, you can conceive a natural number that hasn't a 'referent'.
    Granted. A torrid universe is a possibility for instance. Finite stuff, but no edge. I think a torrid universe requires a preferred orientation for the spatial axes. I wonder if one can get around that.


    I meant to write something like: "if local realism is wrong, is there a non-arbitrary way of distinguishing objects? If so how?"
    Don't understand this. This marble is red, that one is blue. How is that not distinguishing objects, and what the heck does lack of locality have to do with that?

    Eternalism says that past, present and future are equally real. So, it is interesting that, if eternalism is right, we are favoured by a very deep self-deception.boundless
    It has immense pragmatic utility to be so deceived. Evolution would definitely select for it.

    We are potentially truly rational beings. We can be rational but very often we either can't or choose not to be.
    My investigation makes us fundamentally irrational, but with rational tool at our disposal. This is kind of optimal. If the rational part was at the core, we'd not be fit.
    So for instance, I am, at my core, a presentist, and I act on that belief all the time. The rational tool is off to the side, and instead of being used to rationalize the beliefs of the core part, it ignores it and tries to figure things out on its own. But it's never in charge. It cannot be.


    Honestly, I do not get how non-deterministic models are compatible with eternalism. I'll reflect on what you have wrote.
    Suppose physics says that the next state is the square root of the prior state (9). Determinism might say subsequent state is 3, but randomness says it could be 3 or -3. Either value in the block is not a violation of the physics, but if there can only be one answer, it can't be both. It can be there, so eternalism isn't violated, but it can't be predicted from the state 9.

    The only possible way I can think of that they can both be 'true' is that they give good predictions and are useful.
    They don't make predictions at all. If they did, only one would be true. Hence falsifiability.


    To use a probably not very good analogy, it is like to compare a portrait of a human being to the human being. It well represents some features of the human being but certainly they aren't the same.



    I didn't ignore them intentionally - I just didn't notice them (and still don't know which comments you're referring to. The word ‘fallacies’ appears just once on this page, in the post above this one.)Wayfarer
    https://thephilosophyforum.com/discussion/comment/1000411
    Near the bottom. Your replied only to a part of that comment addressed to boundless.


    As first responder herein, I admitted to unabashedly supporting mind-independent reality, which makes explicit something that is, and is necessarily, regardless of what I think about it.Mww
    OK, reality is real because it's necessary. That's something. Necessary for what? What would be violated by there not being anything?
  • Does anybody really support mind-independent reality?
    Well, I guess that's an opening for me to chip inLudwig V
    Well the fact that you reacted to a comment 500 posts means you've been paying attention to this topic, and I must thank you for that and for your contribution.

    I do have a problem, however, that I haven't got my head around what the criteria are for mind-independent existence.
    I don't think my criteria matter at all. It's something that should be explicitly specified by anybody that claims it, so it might vary from one view to the next. Since I consider ontology to be a mental categorization, there's nothing mind independent about it. I'm not asserting that the others are wrong, but I'm trying to explore the consistency of such a view.


    But first, can I ask whether you say that there is no question about the moon because there is no question whether it exists independent of any mind?
    A typical realist would probably say that. I don't. "The moon is real because of empirical evidence". Presumably the moon's existence (relative to this planet) is not dependent on humans (or any life forms) observing it, and yet it's existence is justified by observation. I challenge that logic, but to do so, I need to find somebody who supports it.

    For the record, I typically use the word 'mind' or 'observer' in a physicalist way, both synonyms for information processing of sensory input. There's nothing anthropocentric about it, but others might use the word differently.

    For me, unicorns exist, all right. But they are not real creatures.
    OK, so you draw a distinction between 'exists' and 'is real'. As a mythical creature, it is a common referent. People know what you're talking about, but it seems no more than a concept of a thing, not a thing in itself. I am not talking about the concept of anything, but about the actual thing, so perhaps I should say 'is it real?', or better, come up with an example that is not a common referent such as a bird with 7 wings, all left ones. That at least eliminates it existing as mythology. But instead let's just assume I'm talking about a unicorn and not the concept or myth of one.

    If those stories stopped circulating and got forgotten, those myths would cease to exist
    Side note: Your definition of 'exists' seems to be confined to 'exists at some preferred moment in time', which implies presentism, and only membership in this universe. I consider a live T-Rex to exist since I consider 75 MY prior to my presence to be part of our universe. The notion of 'cease to exist' makes like sense to me.
    I also don't confine existence to our universe which is why I call it 'our' universe instead of 'the' universe. I find presentism to be a heavily mind dependent view. Just saying...

    The bottom line, is that, in the case of unicorns, our intuitions pull in opposite directions.
    The bottom line should be an answer to my question. Do real unicorns (not the myth) exist or not, and how might that answer be justified? Perhaps unicorns are again a bad example of mind-independence because they presumably implement mental processes of their own. Perhaps we should discuss some questionable inanimate entity.

    If I may add a comment on thermostats. We made them to meet certain purposes in our lives. In that sense, they are mind-dependent.
    Anything deliberately designed seems mind-dependent, yes. The thermostat was my example of Wayfarer's query for something not human that performs an experiment and acts on the result of that experiment. I didn't propose it as something mind independent.

    I would say that what exists indendently of our minds is a physical object shorn of its place in our lives. Without that context, it is misleading to call it a thermostat.
    So an alien-made device on a planet out of our access cannot be called a thermostat by us? How about the temperature regulatory systems that the first warm-blooded animals evolved? Both those are sans-human-context.



    Not sure why you said that, after, for instance, the discussion we had about intelligibility and the 'perspectives'.boundless
    Sorry. I didn't see how that discussion actually applied to what I'm asking. Mind independent existence shouldn't be confined only to things that have a certain relationship to a potential mind (intelligibility).


    the question of this topic is not about the moon, but about the unicorn. If the unicorn exists, why? If it doesn't, why? Most say it doesn't, due to lack of empirical evidence, but if empirical evidence is a mind-dependent criteria. Sans mind, there is no empirical evidence to be considered. — noAxioms

    Well, it is a rather difficult point, right?
    I know, and it's one I apparently failed to articulate well in my OP.
    As explored in my reply with Ludwig V above, perhaps the unicorn is a poor example, but it is difficult (contradictory?) to identify something that has no experience associated with it.

    On the other hand, you was pretty explicit that at the fundamental level of your hierachy we have mathematics and mind is after the physical. Ho can you claim that?
    By 'after', you mean mind supervenes on the physical. My hierarchy doesn't count since I'm not claiming mind independent existence. I have existence supervening on mind, so that's pretty explicitly mind dependence. That hierarchy is a proposal, not something elevated to 'belief'. It seems to work pretty well though.

    Well, denying that we can't understand meaning goes against the immediate evidence.
    I didn't say that. There's no claim that 'I' = brain. I'm just suggesting that understanding is perhaps a physical process that takes place utilizing components, none of which understands what the process understands. That equates 'I' with 'process'.

    Also, I believe that there is no consensus that our mind is algorithmical.boundless
    It kind of is if it utilizes classically deterministic primitives, and I've never seen a biological primitive that leverages randomness. All the parts seem to have evolved to leverage repeatability, sort of like how transistors do despite using quantum effects. Sure, it involves a lot more chemistry than does a computer, so in that sense, it's not the same. It doesn't implement an instruction set, but a computer need not do that either. I have designed a few computers with no instructions and no clock ticks.

    Ants do not move and behave as stones do.
    They're life forms, so of course not. But they're bloody close to full automatons. Super close to what a herd of identically manufactured robots would be like, which admittedly aren't designed to work together. Maybe nanobots, which are.
    .
    Not sure why you seem to label 'reality' what I would call a 'representation' or an 'interpretation' of reality.
    Reality is an interpretation of empirical data. That's what I'm calling an interpretation here. People interpret that data differently, so there's all these different opinions of what is real. If being real is no more than an ideal (a mental designation), then there's no truth to the matter.


    How can a thermostat be there long before humans came around if the quality of 'being a thermostat' is mind-dependent?boundless
    It wasn't a named quality back then. Nothing with the language to name it. So was it what we now call a thermostat? It's not like it was this funny isolated object, separate from what it controlled. It was spread out, integrated throughout what needed to have its temperature regulated.

    Yes. I believe that certain classes of metaphysical interpretations are falsifiable, but not broad categories like 'idealism' or 'naturalism'. For instance, a 'local realist naturalism' has been falsified by Bell's experiement (BTW, I believe that even superdeterminism is actually a form of nonlocality...).boundless
    Superdeterminism is supposed to be local, but it kind of prevents empirical investigation, so it's an empty metaphysical proposal, sort of like BIV where all sensory input is rejected due to suspicion of it being lies. Thus superdeterminism is not listed as a valid quantum interpretation since it doesn't conform to data, but rather fully rejects it. Yes, local realism has been falsified. Here, realism has somewhat a different meaning that what the realists mean by the word.

    There is a way to falsify presentism: Just jump into a large black hole. Presentism says it is impossible to be inside one since the interior never happens. No point in doing so of course, but you'll know for sure during what short time you have left to live.

    BTW, as time passes, I am growing more sympathetic with MWI and MWI-like models if interpreted as describing potentialities. I believe, however, that the mistake of these models is to assume that all potentialities actualize, i.e. a belief that whatever can happen, will happen.
    What's the point of MWI if not to point out that all potentialities (valid solutions to the wave function) occur? Some do and some don't? That seems to make far less sense, a reintroduction of dice rolling for no purpose.


    I accept the presence of the antinomy and I think that this implies that we simply can't be certain about what is 'mind-independent'.boundless
    Wasn't the question though. The question was, do you have an opinion about it? What's the most mind-independent thing you can describe, something as unlike an apple as you can get? Does describing it disqualify it? I'm still not clear where you stand with unicorns, or a better example than unicorns.


    Regarding the first sentence, I believe that you have not presented sufficient evidence to say that.boundless
    One does not present evidence of a negative. One provides a counterexample to falsify it.


    But how can we make sense of the fact that the same object exists in different structures?
    Example: It evolves naturally in one and by chance in many others.

    In a sense, to me this shows that math perhaps isn't enough to explain 'things'.
    Yes, it's a huge problem.


    For instance I am not sure that the number ((10000000000^100000000000000)^100000000000000)^100000000000000 is instantiated in our universe, despite being finite.
    You should have grouped the parentheses from the right, yielding a much larger number. Anyway, that number is the distance, in meters, between a certain pair of stars, given 1) an infinite universe, and 2) counterfactuals, the latter of which is dubious. Still, a distance between potential stars then.

    And yet are space and time are quite 'real', right?
    Dunno. You just got finishing saying that these are not defined without a frame, and a frame is an abstraction.

    They are a phenomenological given, immediate features of our experience. Is there a relation between reference frames and our experience?
    Probably, but out experience is physical, the same regardless of frame chosen to describe it. This is sort of like the twin paradox, illustrating that while time dilation is a coordinate effect (frame dependent), differential aging (noting the different ages of twins at reunion) is physical: the same difference regardless of frame choice.


    One, however, might feel the plight of Einstein and ask: "Well, then, how can we 'carve' the world into distinct objects if we can't spatially sperate them??"boundless
    Why can't we spatially separate them?


    If eternalism is right, change is merely illusory.
    Disagree. Change is typically defined as difference in state over time, and eternalism is not incompatible with that. The illusion of time flow is a gift of evolution, allowing beings to predict the immediate future and be far more fit that something that can't.

    But if our experience is so wrong about something 'obvious' like that, how can I trust it?
    Trust it. Just because it isn't rational doesn't mean that it isn't essential for fitness.

    Science, after all, is empirical. If our experience gets something basic like that so wrong, how can even trust science?
    Science actually doesn't render much of an opinion, but rational logic does. Humans are by nature not rational. It takes effort to ignore the biases.

    If the state truly evolves, you can't have a block universe.
    OK, that's one usage of the term 'evolves'. Another is simply that one state is a function of the prior, classically or completely.

    In fact, this is quite close to how I see it. As potentialities, all 'histories' are 'there' and eternalism is right for them. They have a weird 'virtual' existence, so to speak. They aren't 'nothing' but they aren't properly 'something'. Not all potentialities actualize. What is actual is what is truly 'real'.
    This sounds like MWI until the part of about partial actualization. Not sure what it is with that. MWI is a very deterministic interpretation, but with the partial actualization bit thrown in, it ceases to be.

    My point was that you need to have determinism in order to have eternalism.
    Disagree, per the examples I gave. Presentism vs eternalism is merely an ontological difference. If one is possible without determinism, then so is the other.
    Having said that, and having floated the idea that ontology is a mental designation, it would seem to follow that presentism and eternalism are the same thing, just interpreted differently, an abstract different choice without any truth behind it. I hadn't realized that until now.




    My use of appearance merely indicates the presence of a thing as an effect on my senses, which is the parsimonious method for distinguishing the empirically objective from the rationally subjective.Mww
    I find both "empirically objective" and "rationally subjective" to be somewhat contradictory terms. It is quite difficult to communicate with such a gulf in how we choose to use language.

    Where do you find fault with the concept of objectivity, then?
    Objective implies something that is, independent of context. Not being a realist, I find very little that meets that. OK, arguably mathematics is objective, but one can argue against even that.

    Big 'if'. If mind (or life, or intelligence) is truly not reducible, then it's also not really explainable in other terms.Wayfarer
    You responded to a comment to somebody else and totally ignored the fallacies identified in my comments regarding your own assertions.
