    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

    I agree. The interesting part is which items qualify as mind-independent and under what criteria.
    Ludwig V

    For me anyway, the only mind-independent items are those I don’t think about, either particularly, from the lack of occassion yet for which an experience is nonetheless possible immediately upon such occassion, or, generally, from the impossibility of a conception sufficient to represent them, for which there can never be an experience at all.

    This relates iff mind-dependence begins at intuition, not perception, insofar as, with respect to criteria, at intuition is the first representational construct, which replaces the empirically real of things effecting the senses, in a theoretical point of view regarding the human intellectual system.

    I’m not a fan of the concept of mind; all that is mind can be replaced by reason. The explanatory power of mind I can do without; of reason I cannot.

    A thermostat reacts. It doesn’t decide. It compares a set input (say, 22°C) to the ambient temperature and triggers a mechanism based on that difference. It operates entirely within a pre-defined causal structure: stimulus → comparison → output.

    When we perform an experiment, we ask a question about the world and design a process to answer it. There's intentionality, inference, and anticipation involved
    — ChatGPT
    Indeed, there is no decision. There is only one possible course of action, and the thermostat cannot not take it.

    What if a tiny critter has a sensor for food, a sensor for poison, and flagella to take it toward food and away from poison. The sensors weigh which sensory input is stronger, and the stronger gets control of the flagellum.

    So a decision is made.

    Yes, that's an ontological claim, and of mind-independence. That part is easy, and quite common. The challenge is with where it ends. 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.noAxioms
    I think I understand that. So "unicorn" is not an irrelevant example. I like it just because it is not straightforward, but requires some thought. That's much more instructive than the moon.

    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.noAxioms
    OK.

    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.

    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.noAxioms
    You are right. It is curious that we talk of the imaginary friends that some small children have, meaning that they do not exist. Yet it is perfectly possible to imagine something that is real - such as a friend who is absent. My grounds are precisely the ones that you were reaching for - improbability or impossibility. Those grounds are defeasible, but the implausibility of the idea means that it would not be easy to convince me of the opposite - especially in this age of deep fakes!

    As to the distinction between "exists" and "is real", I had assumed that anything that exists is real — Ludwig V
    Contradicting your prior quote: "For me, unicorns exist, all right. But they are not real creatures.".
    noAxioms
    Sorry. I meant to explain that.
    My model for "real" relies on the common use of the word, in which something that is unreal under one description will (normally) be real under another. This contradicts the common assumption that "real" and "unreal" are exclusive, which neglects the fact that many things we would describe as unreal do in fact exist and are real under a different description. Hence "A forged banknote is not a real banknote, but it is a real forgery."

    As I was writing, I realized that unicorns and mythical creatures and 7-winged birds are imaginary creatures and "unicorns are real mythical creatures" and "7-winged birds are real imaginary creatures" seemed malapropisms. But unicorns and 7-winged birds do not, to put it this way, have the same mode of existence as forged bank-notes and industrial diamonds.

    Different definition of 'real' there. We're discussing ontology, not 'being genuine'.noAxioms
    True. I get a bit confused by "mind-indendent reality", which, pretty clearly is about existence.

    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.noAxioms
    If I write something like that, you can be pretty sure it is a joke.

    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 .... 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. .....noAxioms
    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. Until there is better evidence, I shall continue to classify them as mythical and claim they don't exist, except in the way that mythical creatures (Pegasus, the Gorgons, etc.) exist and not in the way that horses exist.

    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.noAxioms
    I see your point. Compare "imaginary". My reply is the same.

    There are many definitions, rarely clarified when the word is used. Some examples:- ..... 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.noAxioms
    Thinking about it, I'm really not content to say that past events and future events don't exist. It makes sense to say that all events, past, future and present exist, but in different modes. "X event happend in the past", "Y event will happen in the future", and "Z event is happening now" are all true and all those events are real, hence exist. So I don't accept 2p.
    I've worked with 4) most of the time, though I would resist the apparent arbitrariess of "whatever we designate" and substitute "whateven the language we are involved in specifies". But I would insist on the truth value. I've talked about different modes of existence in this post. That reflects the effect of context on the meaning of "exist" .

    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.noAxioms
    I don't think you've got that quite right. Surely, the data are also part of reality? Also, on the face of it, it looks as if you are saying that reality is not (directly) observed, so your problem disappears. I'm not sure about reality, but I'm pretty sure that what counts as real depends on the context. "Real money", "Real food", "Real champagne" all have different definitions.

    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.

    Edit. Text deleted here.

    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.noAxioms
    Thanks very much for that. It was very helpful.

    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.noAxioms
    Yes, I've gathered that modern physics seems to have become something that Bishop Berkeley would have approved of, - apart from the refusal to include God. But there also seems to be very little consensus.

    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. 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.

    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.

    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.

    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.

    Yes, it is tempting to treat the future differently from the present or past. Perhaps the ground is that the the future is undetermined while the present and past are determinate and can't change. But one needs to show that this is quite different from the generalized uncertainty that would point out that our belief in X or Z is also defeasible. The determinism, whether logical or causal, will chip in to demolish us completely.

    Well, if all my actions are deterministic, it is quite controversial to attribute to myself moral responsibility. After all, I literally could not have behaved otherwise.
    Probabilistic choices are no better. Yes, I could have acted otherwise but, again, how can I be blamed if, ultimately, my choices are a result of a blind mix of deterministic and probabilistic mechanism?

    To make sense of moral responsibility, you need to impute to moral agents some deliberative power and a sense of right and wrong.

    Of course, ethics is something external to physics. But I would like that my 'worldview' is something coherent, a stable unit. It is difficult to 'believe' to have free will half of the time becuase I have to assume it to have a coherent concept of moral responsibility and in the other half 'believe' that I have no free will.

    Well, Rovelli proposed that in reconciling GR with relativity, the spacetime of relativity gets quantized because it is the gravitational field and like other fields become quantized. However, 'time' as a measure of change remains. Same goes for space, if it is interpreted as a relation between things.

    So, perhaps uniting GR and QM resolves the 'tension' between the apparent denial of the 'flow of time' and our experience.

    It is good to hear that, thanks. 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 believed (and was the concept that inspired Bohm to have more speculative ideas like the 'implicate order', 'active information' and so on that also have been adopted by Hiley) and the somewhat more 'restrained' but still different versions of dBB by people like John Bell and Antony Valentini, who treat the wavefunction as a physically real field that guides the particle but make no mention of the quantum potential. 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. There is no explanation of why particles move in they way they move. They just move that way. The only advantage with respect to a 'Copenaghen-like' view is that here you can easily visualize 'what happens'. But there is absolutely no explanation of why particles behave the way they behave.

    Suppose you started with recognizing two facts. First, we sometimes act freely. Second that the world appears to be deterministic. The only problem is to develop an account of those two facts that recognizes both. Doing that will require rejecting the concepts that are taken for granted in formulating the problem. For example, free will is defined in opposition to determinism, so we need to get rid of that concept. It doesn't make any sense anyway. Determinism, on the other hand, is treated as if it was true. But if it is true, it is empirically true, and I don't see how we can possibly know that, so we need to think that through again.

    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.

    Yes. How did you type your response and send it over the internet to me? 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? Reality constantly smacks us in the face with a two-by-four with contradictions daily to what our mind wants to believe is true.

    There is often a confusion between "What we know" and "What is". What we know is what can be best reasoned with the limited information we have. But even that knowledge could be contradicted one day if we haven't yet encountered everything that involves the knowledge claims reasonableness.

    What we know is clear: There is a world independent of our own minds. Does that mean we've grasped that world accurately? What does accurately mean? To create a concept of the world that when applied is good enough for most purposes. Gravity accelerates at 9.8 meters per second on Earth. For most calculations, this gets us the outcome we predict consistently. And in this regard we have what could be considered an accurate assessment of reality independent of a mind. We didn't set gravity to accelerate at 9.8 meters per second on Earth, we discovered it.

    Mind independence doesn't mean what we might think it means. When talking common-sense realism: of course the moon exists when nobody is looking, and the tree falls in the forest where nobody can hear. And on a common-sense level, that is quite true.

    But the question of whether things exist independently of the mind, is not the question of whether they exist whether or not you or I, in particular, are aware of them. The question arises from the realisation of the role of the mind in perceiving what we know to be the external world. The brain and the central nervous system are in contact with the world through the sense-faculties of sight, hearing, touch, taste and smell. 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. It's not something infants see; they have to learn how to see it, an act which takes the first few years of life.

    'Sure', might be the response 'but even if you're not conscious or not there, "the world" continues to exist.' And in one sense, it does - but again, we only know that, because we're able to consciously contemplate it. We have an innate sense of its existence, and all of the empirical data indicates that it existed before we, as individuals, were born, and will continue after we die. But that knowledge is still grounded in our 'mind's eye', so to speak - even our knowledge of what it is.

    Realism neglects the role of the mind in this process. It takes the world as given, without considering the role the mind plays in its construction. That is the context in which the idea of mind dependence or independence is meaningful.

    This is a bit of a distraction. However, let me say that I think that most philosophers do actually decide to live with the dissonance. Perhaps they actually prefer the argument and would be disappointed if they couldn't have it.Ludwig V

    Ok, but I think that 'truth' is not contradictory. Philosophers seek truth and I would assume that there is a way to reconcile these things. If determinism and probabilism can't give a reasonable account of moral responsability it is quite a deep problem.

    Suppose you started with recognizing two facts. First, we sometimes act freely. Second that the world appears to be deterministic. The only problem is to develop an account of those two facts that recognizes both. Doing that will require rejecting the concepts that are taken for granted in formulating the problem. For example, free will is defined in opposition to determinism, so we need to get rid of that concept. It doesn't make any sense anyway. Determinism, on the other hand, is treated as if it was true. But if it is true, it is empirically true, and I don't see how we can possibly know that, so we need to think that through again.Ludwig V

    Not sure about your point here. Are you saying that we can still 'believe' in free will even if all empirical evidence goes against it because, even if there is no free will, we can't be certain of it?
    To me that would be self-deception.

    We generally do not held accountable people if they could not act otherwise (e.g. for instance, one might be regarded as 'not guilty' due to reason of insanity - the assumption here is that the transgress didn't have the capacity to act otherwise).

    Right, if closed systems are either deterministic or probabilistic nothing really changes. I think that it is a questionable assumption but I respect it. After all, there are good reasons to regard it as true so it's not irrational. I do believe, however, that a more 'complete' picture that gives the due importance to ethics suggests that such an assumption might not be valid. Or at least that there are heavier consequences than what it is generally assumed.

    Yes, sorry for that. But I don't treat different areas of culture as separated from each other. Scientific knowledge isn't something that has no effect on ethics and vice versa. Both are quite important and if they contradict each other there is something amiss in one or the other. From a practical point of view, I would say that ethics is even more important. So, I don't think that we should ignore the fact that some of its constitutive assumptions seem to be in tension with what science tell us.

    But yes, it is off-topic.

    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.

So we really need a unified theory to speak the same language about both theories.noAxioms

    In the 'wave function as a law' model the laws are simply descriptive. There is no 'pilot wave' that guides them, no causal agent for their motion. That's why I said it is a kinematic model. Both the Bohm-Hiley and the Valentini-Bell variants do have a dynamics. In the first, there is a 'quantum potential' that depends only on the form of the wavefunction (that's why in later years Bohm thought that it is a kind of 'informatiuon pool' and the particles have some kind of ability to decode information) that act on the particles with a 'force' which in turn causes an acceleration - all is described as in classical physics with second-order time derivatives. The other 'realist' model doesn't use the quantum potential. It is also a model that uses only first derivatives of positions and, according to Valentini, it is a very big difference with respect to classical mechanics.
    Still, both models treat the wavefunction as a causal agent. This isn't true for the 'wave function as a law' model. While the latter is better than superdeterminism, it is still curious that one wants to make a CFD model without a dynamics.

    Well, Bell proved mathematically that no 'local realistic' theory can make the same predictions of QM (outside some problematic loopholes like superdeterminism). In itself it is a powerful result. Of course, the 'experimental proofs' came later. The first experiments however were made in the 80s and Bell was still alive.

    Nice article BTW.

    Realism neglects the role of the mind in this process. It takes the world as given, without considering the role the mind plays in its construction. That is the context in which the idea of mind dependence or independence is meaningful.Wayfarer

    Right. Honestly, part of the problems in these discussions is that 'realism' is often assumed to be the position that there is something that exists even in the absence of our minds. This of course gives an incredible amount of 'realisms'. Physicalism is a type of realism. But also theism is. But even epistemic idealism is a form of 'realism' becuase it doesn't say that reality is only minds and mental contents.

    'Realism' is, however, also an epistemic position. It claims that there is a reality different from minds and mental contents that can be known by mind as it is. Of course, even with this definition realism covers a lot of positions. But with this definition realism excludes an epistemic idealism or a skeptical position where nothing outside minds and mental contents, representations etc can be known and also an ontological idealism where there is nothing outside minds and mental contents ('weaker' forms of ontological idealism, which claims that fundamental reality is mental but do not deny the existence and the knowability of something different from minds and mental contents however are in fact forms of realism).

    In order to prove 'realism' in this sense one should be able to identify what can, with certainty, be said to be different from minds and mental contents (including representations). That is, one should be able to distinguish 'what pertains to reality as it appears to us' and 'what pertains to reality as it is itself'. Contrary to appearances, when one considers the regulating role that the mind has in ordering our experience it becomes quite hard to just do that.

    Yes - "too compromised" means "not working as it should or normally does." If their mental state was normal, we would hold them responsible. Yet a deterministic account cannot point to any significant difference between those states. Compromised state and uncompromised state are all the same to it. So our judgement is made in a different framework or category. In practice, when people are behaving normally and their mental state is not compromised, we do not bother with the causal, deterministic level of explanation. We only pay attention to it when things have gone wrong, and those normal explanations don't apply.
    Let me offer you this. It seems to me that there is no problem whatever in seeing rational action as entirely compatible with determinism, because calculating machines can perform calculations and yet we know that they are also behaving deterministically. But we only pay attention to the deterministic level of explanation when the machine is not functioning properly. When it is working properly, we have no doubt that it showed the result 4 because it was asked 2 + 2. We don't appeal to its causal states, because they cannot distinguish between correct and incorrect answers, so causal explanation wouldn't explain anything.
    Okay, it's not freedom. But it is a step in the right direction. The key is the recognition that actions, as opposed to events, are explained in a different category from events.
  • boundless
    555
    Honestly, I do not find that convincing at all.

    If our actions are truly deterministic and we could not have acted otherwise, the only way I can think about 'ethics' is being exactly like medicine. So, we act wrongly and we are held accountable and get punished in order to 'get well' later on. I guess that upo to a certain point I agree. In fact, I am ok with the classical 'virtue ethics' where good act are good because they fulfill our nature. So, in a sense, yes, I agree to treat ethics in a medicinal way. But, as always with analogies, we also have to avoid to take them too far. When we do wrong it is not that we were coerced by internal or external constraints to act in that way. We are influenced by those constraints, but there is a 'window' of freedom that we can't ignore and that 'window' is what makes 'accountability', 'culpability', 'moral responsability' meaningful.
    So, yeah, I guess that my view is that compatibilism gets something right but can't tell the whole story.

    Also, if we were not free, I even doubt we could consider ourselves as distinct beings from the 'rest of the universe'.

    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.
