  • Being? Working? Both?
    Being is dynamism or chance constrained. Steady existence is what you get once a process has gone to an equilibrium balance and now simply persists in spite of any microscopic shifting about.
  • A particle without a top or a bottom?
    An atom was uncuttable matter. But it still had a shape or form. It still had a location and so a potential for motion. Relatively speaking, it could have a top and bottom from some point of view.

    It depends how you are thinking of top and bottom. Are they actually parts or contextual and holistic properties? Are they parts of the material being or parts of the atom’s form?
  • Commonsense versus physics
    So your pure data vs empirical data distinction is less equivocal here?

    You would have to explain.
  • Commonsense versus physics
    It sounds a little bit contradictory to say that physics does not aim at the literal truth, but perhaps I'm being unimaginative. Anyway, is it really the case that modern physics undermines commonsense?jkg20

    A way of looking at it is that commonsense supports an objective notion of realism. We naturally believe that we exist in a world of "medium-sized dry goods", to use the metaphysical phrase. The world is composed of material, mind-independent, objects like cats, chairs, mountains, stars.

    But physics itself is a disguised idealist, or internalist, project as it accepts that minds only model realities. So there is a world "out there", but we only gain knowledge of it via the rather particular thing of a pragmatic modelling relation.

    This epistemology puts us somewhere in-between the two extremes being suggested - either that physics sees things as they really and truly objectively are, or that instead physics simply spins some essentially arbitrary human fairy tale.

    This in itself ought to be obvious, not a surprise.

    So what then becomes interesting is the particular distortions that may arise due to this being so. What is physics getting righter than "commonsense" and its object-centric notions of reality, and what might it be getting wronger to achieve that?

    One of the big issues would be the way that physics made its quick gains by leaving the observer out of its models. The conscious self was made a mystery because physics became a model of an observer-free universe. It became a story of deterministic matter - parts in motion following laws.

    As I say, that was a pragmatically realistic way to go. It defied commonsense - the kind of commonsense that used to believe in a nature that was animistic and divine - in a way that seems deeply right. The universe does appear to be objectively composed of particles and forces. But then, with quantum mechanics in particular, the observer turned out to matter.

    Much progress had been made in squeezing the mind out of the physical picture. But in the end, we still need a theory large enough to account for the presence of mind - or some physically general notion of observers and points of view - along with the objectively robust looking observables.

    So the situation really is that commonsense just takes a baseline biological view - the way the world would look to a species that just has to move about, mate, find food, get by. It is a pretty physics-free view. We just need an intuitive sense of how heavy objects behave in contrast to light ones, and how inanimate objects react compared to live ones. We need to make useful distinctions in heuristic fashion. End of.

    But physics took on the task of separating out the distinctions in a robust dichotomous fashion - along the lines suggested by metaphysical thought.

    A first such rational distinction was between animate and inanimate. It kind of seemed obvious that lions and boulders were different in some deep way. Eventually that became the dramatic difference of mind vs matter. And physics reduced everything it could towards the material pole of being ... as us humans could then supply all the mindfulness, or understanding and purpose, needed to animate the states of matter.

    So physics clarifies things in the fashion we find most useful. And it is a trade-off. We make part of our reality - the mindful part - more mysterious, or more contingent and free, to the degree that we make the other - the material part - subject to fixed and explicit laws, or objective notions of existence.

    Thus commonsense was a kind of self~world division - the one that evolved as a neuropsychological level view of reality. And physics is a systematic development of that which worked by making a very strong division between the self and the world.

    And key here is not to get hung up on the idea that physics has thus left out the "mystery of consciousness" - the soul, the spirit, the ineffability of qualia, etc.

    There is psychological science, after all. There is information as well as matter, complexity as well as simplicity, to consider.

    So where physics does make strong contact with the "mindful" aspect of nature is its fundamental mathematical patterns - the symmetries and symmetry breakings that have turned out to be the deep ontic structure of reality.

    We discover the world of mathematical "objects" through rational exploration. And for physics, they are real, not subjective. So physics is more balanced than its arch-materialism might first suggest.

    It is still targeting an observerless or objective view of reality. But this does include the world of Platonic form as much as the world of material things. There is a reduction going in both directions. Or rather, a dichotomisation - a separating out - that places us ever more explicitly poised between two polar extremes of conception.

    So commonsense is the rather tame and biologically adaptive view of reality. It is the simplest way to for a smart primate to make ecological sense of its perceptual environment. We just have to be able to tell boulders from lions in terms of the way these kinds of things might behave. We just have to be able to make our way in a reality imagined in terms of a clutter of medium-sized dry goods.

    And then physics divides this view as sharply as it possibly can. We get a pretty much complete separation in terms of material actions and formal organisation. We conceive of reality in terms of these complementary categories - material/efficient causes opposed to formal/final causes. We generalise the matter~mind divide so that it becomes a division between the naked materiality of quantum action and the pure form of mathematical structure.

    Now which is the "real" view of reality - the rather humble evolved view of commonsense neuropsychological mechanism, or the rather exalted view of mathematical physics which sees everything in terms of structured excitations?

    Well, both would be that in-between thing of being simply the pragmatic view - the modelling relation that produces the greater thing of a "self" and "world" in productive interaction. But the commonsense view would be the rather embedded biological view - what you really need back in the ordinary world of boulders and lions. And the physics view is the sweeping view that may deliver some extraordinary new benefits - of great use to humans with an interest in controlling their worlds - but which might also be criticised if it tips over into the unpragmatic.

    In the end, physics is only a human endeavour. And so it becomes an issue if it pretends to be an actually objective and detached exercise.

    What I am saying is that physics has to include the realisation that it exists as part of a modelling process. It has to strike a balance that neither pretends to be a completely human-less and objective thing, and alternatively, a completely human-centric and subjective thing.

    Again, the usual epistemic quandry is whether physics is realist or idealist, a fact of the world or an artifact of the mind? But it is this third thing, this in-between thing, of being an example of a pragmatic modelling relation. And that is how its truth claims - especially versus those of commonsense phenomenology - need to be judged.

    We use grammar in a way that seems to point to mental furniture; but that is an artifice of our grammar.Banno

    Back to front. We use the structure of language to constrain our phenomenological state so that it has “mental content”.

    That is, the way to avoid the dualism of idealism vs realism is to recognise that language creates the self that has the point of view along with the mental furniture it now appears to be observing.

    A relation that starts in an embodied or enactive fashion - out in the world as a habit of interpretance or behaviour - is internalised as a meta model of a self that is in interaction with the world.

    The human mind comes to experience the world as a place with ourselves in it. The animal mind only experiences the world, with any selfhood as merely a running intentional context, not a further “mental object”.

    So language use and truth telling rely on this semiotic displacement. There has to be a model of the modeller. We have to form a (social) concept of “our self” - the self whom experiences the observable facts - to be public creatures having private states.

    That’s what’s funny about your naive realism here. It has to combine a naive realism about the mental furniture - pretending it doesn’t exist, the facts just are - with a naive realism about the self. You argue the self has to drop out of the picture because it is private, yet the self is the socially constructed bit, the necessary creation of the public discourse.

    Check out symbolic interactionism or Vygotskian psychology. The pragmatist cleared all this up ages ago.

    You can have all the phenomenal states you like. I'm pointing out that if they are private, then they are irrelevant; and if they are public, they are just the everyday stuff we already talk about - colours and beliefs and such.Banno

    So what is this public state but the belief that the private state is sufficiently shared?

    Is there a public state unless you have phenomenology in play? It you talk to the wall, is that a conversation? If you talk to the cat, is that some kind of conversation? If you talk to yourself, is that not a kind of public act too?

    So the I or the we doesn’t fall out of the picture. The whole point of the deal is this tricky relation between what you call the private and the public.

  • The Body as a Diagram of Forces (with Diagrams!)
    Again that is half the story - the dynamical bit. The other half is the informational bit - the regulation or semiosis that switches logarithmic growth processes off and on.

    That was one of the points about effective field theories. They model a hierarchical or fractal development of scale - the bit that renormalisation describes as a homogenous ground state. Yet - rather artificially - limits must be inserted to prevent infinities that would blow things up. Some kind of "regulator" - like the imposition of a lattice, fractional dimensions or mass cancelling particles - has to be added to the ontology.

    So nature is growth plus switches. Bodies are formed by dynamical and self-organising growth processes. But genes need to provide the schedule that knows when to turn the growth on and when to turn it off.

    You forgot to mention the "irreducible, invisible thing-in-the-mind" which is a sense of things being surprising or unsurprising in relation to "heaviness" revealing behaviour.

    If someone is asked to lift a fake weight, will they show they had a belief in terms of a state of trust not being maintained? (As @javra very astutely points out.) And if the weight is as heavy as it naively looks from experience, will there instead be a sense that things are just how they were conceived?

    I conceptualize nonlinguistically and find myself searching for words to express those concepts.Hanover

    Yep. And for those pushing a tight identification of thought/belief :) with the human-only power of grammatical speech, that question usually leads to the argument that there is a further hidden level of mentalese - https://en.wikipedia.org/wiki/Language_of_thought_hypothesis

    But the alternative - some kind of Hebbian or Behaviourist associationism - has its own serious problems. The "nonlinguistic" part of your searching for words has to have some flavour of a Hebbian network competition. And that we would have completely in common with animals.

    Yet neither extreme could get it right all on its own. Hence why a semiotic approach is needed which can marry the two halves of the puzzle.
  • More Is Different
    But I do not find the criticism "context invariant" as damaging to a method of explanation, such as the reductionist's. This does not weaken their theory. Why not? It's because context-driven explanation must necessarily use some form of reference point to relativize. And this point of reference must necessarily come from the fundamental laws themselves, which the reductionist had already set out.Caldwell

    The problem is that regular reductionist physics targets equilibrium descriptions of nature - nature that has "emerged" in the sense of crossing a critical threshold and now seeming utterly stable. The dynamics are so dead that any source of change or individuation has to be imposed as a further cost or effort.

    And that is fine. The contextual or the relational drops out of the picture in terms of accounting for the proximate causes of change. It simply becomes an inert or a-causal backdrop. The taken for granted reference frame.

    But the physics that is interesting to emergentists is the physics of the boundaries, the critical thresholds, where the dynamics are still poised or unstable - and hence, switchable. The zone of non-linear instability is where interesting things can happen because that is where information can start to insert itself into the process and control the bifurcations or symmetry breakings for its own reasons.

    So there is a whole physics of instability - and the distal causes that can regulate that. And that kind of holistic physics is what can be made large enough to include complexity in general, and also in particular, as the complexity that has the autonomy of life and mind.

    In other words, it becomes a physics that includes both information and matter. Where things are materially wobbling on the cusp, that is where information - or semiosis - can insert choices about which way to wobble things.

    And it is not as if quantum theory - as our most fundamental theory of materiality - isn't already telling us just this. It is all about the instabilities that get regulated by a mysterious "collapse" - the insertion of an "observer" asking questions that stand for some particular point of view.

    So all our best physical theories are completely mechanical and observerless - right until we get to the point where the fundamental instability and contextuality of nature can no longer be ignored in our theory building.

    Holism has already beaten reductionism at the level of metaphysical generality.

    Reductionism is the most efficient, or least information-requiring, way of modelling a material reality where all the symmetries have been broken to the point that the system has gone to stable equilibrium and all the contextuality can be summed up by a simple macro-state number.

    But science keeps developing. Over the past 50 years, it has started to get its head around the more general case of modelling a non-linear and relational world.

    It's kind of like how the Euclidean presumptions of Newtonian cosmology turned out to be a highly particular view of the total physics that was possible. Non-Euclidean geometries were the more generic physical model in fact.

    So yes, we must impose a stable reference frame to allow some system of measurement - a firm base on which we can construct a story of local deterministic causes acting in an a-causal void.

    But it will always be revealed that this in itself is a choice made by an observer. And so it can't be the largest model of the physics if it doesn't also include that observer.

    Which is why we need the kind of holism that is about information or semiosis regulating the inherent instability of nature. Biology, for one, is on to it.

    How do we normally use the word concept?Sam26

    Normally it means an idea - particularly an abstract idea or an idea that is a mental picture of a set of relations.

    For example, a "right angle" is a concept. Giving it a name, and even that name a definition, doesn't seem to be enough. You would need go draw it, measure it, experience it in enough contexts, to really get the idea involved.

    Now pigeons can be taught to recognise the concept of right angles. They can indicate which of two images is of a more "right angled world".

    And certainly in cognitive psychology, a concept or schema is understood as the abstract or general structure that we impose to create organisation in our states of impression. It is standard linguistic practice within the relevant science to think that animals are conceptual in that fashion.
  • What is Scientism?
    The second point is that, scientism is inherently anti-philosophical in nature. It poses as philosophy, and adopts philosophical rhetorics, but ultimately it seeks to undermine philosophy by only admitting what can be definitely known, measured and assessed. The point about the Western philosophical tradition is that there has always been a place for the unknowable, for aporia, questions which really can’t be neatly resolved but need to be asked nonetheless. Whereas scientistic positivism declares all such questions out of bounds.Wayfarer

    I would say the difference lies more in the quality of the evidence being accepted.

    Mystics are quite happy to claim proof of their theories in terms of feelings, intuitions, revelations and surprising coincidences. You, for instance, regularly cite oceanic experiences as proof of transcendent being. All “philosophy” is empirical in the sense that the structure of explanation involves relating the particular to the general. We have a broad belief because it appears to account for many and varied impressions.

    Dig into scientific positivism or instrumentalist enough and I would argue that you discover the underlying pragmatism that in fact sees even “measured evidence” for what it really is - the reading of numbers off dials.

    So it is all experiential. But then it is experience rendered in mathematical signs. And this in turn is secured in the western philosophic tradition by our recognition of the unreasonable effectiveness of mathematics.

    You are always pointing out how Platonism seems to be trying to tell us something deep. Science actually relies on the language of numbers, the rational structure of mathematical relations. That is what it uses to harden empiricism and give experience some actual kind of transcendent status as a form of evidence.

    What you feel is what you feel. It lacks objective distance as evidence. It lacks disambiguation,

    Science employs number as a rational structure that gives that safe distance. It is the general of a mathematical structure that becomes related to the particular of some act of counting. And so it’s empirical evidence both accepts the subjectivity of our reality models, but also deals with that in the best quality way possible.

    The fact that science wants to give everything a number rather than a feeling is the feature, not the bug.

    And that was always what was distinctive about the Western metaphysical tradition that arose out of the universalisation of mathematical structure in Ancient Greece. What you call Scientism is simply what has worked best for understanding reality ever since then.

    And I agree as usual that Scientism has the flaw nevertheless of being overly enamoured with bottom up construction - bottom up construction being the way mathematical operations generally have to work. Another issue.
  • Belief
    I'm increasingly convinced that beliefs are a folk-psychological back-construct; that they are an invention that serves, however poorly, our attempts to explain what we do; but which does not correspond to anything real.Banno

    The mental reality is of course often much vaguer or more indeterminate than the words called forth to account for it.

    That just is a consequence of the human mind being composed of two levels of semiosis - the neural and the linguistic. Language imposes it’s more definite structure on the inherently less definite neurological goings on.

    So a belief described to another in words takes the form of some overly concrete set of reasons.

    And that linguistic sharpening shows here in your own post. You - due to linguistic habit - reject vagueness as an option. It has to be a case of either/or. Hence if you can’t believe that our words describe some actual mental object, the only dialectical possibility is that there are no mental objects in any sense.

    Yet ambiguity is part of the whole business, as we know. In practice, we have the art to navigate the gap and talk about our beliefs as if they were communicable objects while also retaining their individually experienced ineffability.

    So you are imposing a false dichotomy on the situation. We regularly navigate the difficulties involved in using language to sharpen cognition. Our actual thinking copes well with ambiguity of reference.
  • More Is Different
    It's important to note that this is entirely implausible on any reasonable reading of M-P, who spends page after page in the Phenomenology arguing against such a view.StreetlightX

    Hah, yes. I admit that saying M-P was veering right towards a sense-data view was a wild exaggeration on my part. M-P's basic gestalt approach is of course very good - exactly the systems causality I would argue. And Brender gives a wonderfully clear account of that.

    So I am thinking more of the ambiguity that Brender identifies....

    Merleau-Ponty distinguishes his position from transcendental idealism by insisting that form does not require a consciousness to constitute it. But in order to distinguish his position from materialism, Merleau-Ponty argues that physical form is a perceptual being, “conceivable only as an object of perception.” (SB, 144) Even if we understand perception as a bodily rather than an intellectual activity, this formulation seems to reinscribe the logic of transcendental idealism at the level of vital behavior, placing us right back in the old antinomies:

    https://philpapers.org/archive/MOSSAS-2.pdf

    ...so the issue is there according to the paper.

    And Brender argues that Thompson rescues M-P from this veering into a idealist grounding. Although I then agree that M-P is always aiming at an essentially logicist account, a structural account, in intuitively understanding that the forms of nature are emergently self-organising. They will snap into place holistically in gestalt fashion.

    Really, the paper is very good. And rereading it with more time, I can see better now how it addresses a weakness in the Peircean story. It allows one to place a sign in the mediating zone that is behaviour.

    The relation between consciousness and nature is split in two by the appearance of behaviour as a mediating term...

    From a more strongly logicist view, a sign can seem like a token, a static symbol. It is hard to see how "a mark" can stand for an actual lived connection with the world. It sounds too much like still being an idealist and representational approach to the issue.

    But behaviour puts the sign out in the gap between the mind and the world. It can be a two-way connection.

    And so we can understand the sign as in fact a switch or gestalt-driven bifurcation. This is what Brender makes clear in discussing dynamical systems theory and autopoiesis. What we call the sign is really the mind is putting out there a binary choice - a suggested instability that represents a dialectical choice as to which way to jump. And then the world bumps up against this neurally-encoded suggestion and tips the balance one way or other with gestalt counterfactual definiteness.

    So a sign is not something already an object in a single definite state waiting to be read. A sign is a binary choice being suggested - an instability that must have its poised symmetry broken in one direction or the other.

    Do I see a cat? The image of whatever it is must be resolved decisively by some set of binary perceptual judgements. Its ears are pointy and perky enough not to be a dog or a rat. Its face is flat enough not to be a fox. Its tail is not too bushy nor too hairless.

    So the signs aren't representational in themselves. They represent dialectical switches going off - logically-sharp hypotheticals about the world that then get nudged just enough to trip them decisively and result in a stable interpretation.

    The larger story is that the world itself is formed - by its own much longer run history - of a whole concatenation of such symmetry-breakings. So the mind is only reflecting the dynamics of the world in a modelling relation based on this rapid fire Bayesianism. We are seeing in a flash - by throwing out there a whole set of super-sensitive switches - the history that produces "a world of objects, a world of medium size dry goods".

    So what on one view seems like mere data processing - imposing a conceptual framework on arriving sense data - would be the more profound thing of recreating in a flash the entire casual history of a process that must lie behind the steady objects of experience. A cat is seen as a cat in a way that truly reflects the ontology of nature. The context, the constraints, that would be needed to conjure up a cat in a place at a time are part of what we perceive.

    And of course the enactive turn in psychology captures that probing nature of signs very well. Unless there is "behaviour" - a move that reveals an effect - then there is nothing to connect the mental to the physical, the model to the world.

    This in itself is hardly an original thought. It was prominent in Russian neuropsychology - the post-Pavlovian work on the orienting reflex. And also in cybernetics. See perceptual control theory in particular - https://en.wikipedia.org/wiki/Perceptual_control_theory

    But it does give a better understanding of a semiotic sign as being a behavioural switch. It is not a sense-data - a passive element already inscribed in some mentalese - but a choice of which way to jump put out there in the world as an active uncertainty. Only the reality of an interaction can nudge matters one way or the other. So the sign represents a dichotomy, a possible symmetry-breaking, rather than a point of reality, a bit of information, that somehow - magically - finds itself crossing the gap between the world and the mind.

  • More Is Different
    Have you read the paper by Noah Moss Brender that StreetlightX linked to recently (Sense-Making and Symmetry-Breaking, Merleau-Ponty, Cognitive Science, and Dynamic System Theory)?Pierre-Normand

    Just read it quickly. I like the phenomenological slant. And I like the nice summary of symmetry-breaking as differentiation or individuation.

    The point of my last long post is that symmetry-breaking is really a dynamical process. Traditional physics has only focused on the EFT view - where the dynamics have gone all the way to equilibrium or heat death. Asymmetry has been achieved for good in that the locally emergent forms have become now the universalised rule - a habit to be taken homogenously for granted.

    But a biological or semiotic view sees the larger reality - the one in which the dynamism is still in play for the world. Now contextuality is a living parameter. The rule of some collective form applies only in some relative degree. And it is the hidden non-linearity of that phase transition which makes it eminently "switchable".

    If change was always boringly linear and gradual - adiabiatic - the Cosmos would never have been anything other than a cooling~expanding bath of thermal radiation. Complexity - with all its own emergent properties and laws - depends on the orthogonality of abrupt ruptures.

    Again, emergence seems mysterious to reductionists as its essential story is hidden off at right angles to the universal gradualism that bottom-up summation or construction can imagine. But sudden transitions are completely natural. Non-linearity is more fundamental than linearity - a dynamicist would say.

    So once instability (as in quantum indeterminism or Peircean tychism) is understood as the more fundamental condition of nature, then the best explanation of nature is the pan-semiotic one - the one that speaks directly to the context that controls the abrupt switches in global state.

    The cosmic issue is not how does change happen in an essentially timeless and changeless world, but how can unbound change become so firmly regulated? It is all about the emergence of downward acting constraints. The meaningless fluctuations can pretty much be taken for granted.

    On Brender's paper, what made me think was the contrast between the phenomenology of Merleau-Ponty and Peirce.

    One tries to assimilate ontology to the fundamentals of sense-knowledge. The other instead tries to assimilate it to the fundamentals of logic or rational inquiry.

    I think Peirce goes directly to the issue of form - the structure of intelligibility itself. That is why he shines for me. It is phenomenology. But it aims for that general structural logic.

    While the Merleau-Ponty school is headed towards a sense-data view - one that risks takes qualia too seriously as drops of conscious experience.

    So yes, you can pull back from that and steer the phenomenology towards a modelling relations view. You get back towards a semiotic story. You can understand how it fits with an enactive approach to cognition, or Rosen's relational biology.

    But that makes this route - veering towards the senses and away from logic - a rather indirect way to get to the ultimate destination of a process view of structure and form, a metaphysics based on existence as intelligible organisation.

    Still a nicely argued paper though.
  • More Is Different
    Yeah. But how do you not understand symmetry breaking? :)

    You are an engineer. You must be familiar with classic examples like the magnetisation of a bar magnet, or an Ising model.

    What about a buckling beam? Or the onset of turbulence? These are very concrete examples.
  • Is dark energy the outflow of dark matter from a universal black hole?
    But blasting dark matter out to create "cosmic voids" doesn't connect with a dark energy story of a faint added accelerative repulsion that is part of the void itself.

    It just spreads the gravitating mass about. It doesn't create a new generalised source of "antigravity".

    And there is no reason to think it would create an anisotropy. Why would these supermassive blackholes be distributed in a non-random fashion? What extra factor are you claiming would be in play?

    Again, I don't see the dots being connected. You would have to provide the motivating argument.

    Now it is also quite possible that a belief in dark energy is wrong. It is merely an optical effect - http://www.canterbury.ac.nz/news/2017/uc-cosmologists-reframe-dark-energy-debate-with-new-supernova-study.html

    But of course we do have a missing mass problem. And more than that, dark energy ensures the Universe - being apparently so evenly balanced - could defeat the prospect of a gravitational collapse. So - like inflation - it is a useful idea to be true.

    You seem to be headed towards a hypothesis that creates more problems than it would solve. So there would have to be good evidence of an actual anisotropy to want to go there.

    Just saying. Physics would accept weaker evidence for an effect that reduces complexity - like dark energy or inflation - than for an effect that would increase it.

    Hence you have to provide a good motivation for why the way you are heading would simplify anything for cosmology.
  • More Is Different
    I find Crowther’s presentation very confused - upside down indeed.

    But anyway, the essential point about superconductivity is that QM gets restored as having an effect at low temperature.

    Electrons themselves emerge as the universe cools enough for them to pop out of the quantum foam as classical point particles with individual momenta or incoherent kinetic energy. They are fermionic and disentangled. So in EFT fashion, symmetries are broken and new universalised properties are established. Electrons become a universal thing described by their own emergent EFT - as in classical electrodynamics.

    But cool down their world even further - and make it the world of a confined metalic lattice, another pretty arbitrary and non-universal or non-holonomic constraint - and you get a recovery of a quantum possibility. You can get point particles behaving like collective phonons with bosonic statistics. The asymmetry, or broken chiral symmetry, of being a fermion can be reversed by teaming up as "Cooper pairs".

    So a general rule of the quantum level - Pauli's exclusion principle - becomes again explanatory of what is going on at a "super-classical" level. Electrons could be melted back to pre-fermionic matter - effectively - by travelling back in time to the white heat of the Big Bang. And they can also lose their fermionic identity at the end of time, when things get so cool that pairs of electrons can find it easy to entangle as symmetry-increasing combos. They may still have some individual kinetic momenta, but that is now so weak it can't combat the stronger urge to unit as a way to meet the energetic constraints imposed by a motion through a metallic lattice.

    This all makes BCS a bad example of a "tower of EFTs". It kind of combines two different things at once. And that is confusing.

    Let's step back a bit.

    The key thing about EFTs is they are about a collective mode of organisation being spread out absolutely everywhere and so becoming a “law”. It is about a phase transition that occurs when a limit is "crossed".

    For example, in a world of gaseous H2O, it is the law that the molecules behave everywhere and at all times like a liquid when the temperature and density crosses a critical threshold. The collective behaviour - due to weak van der Waals forces - overcomes the individual kinetic energies of the molecules. And so a new state of matter arises - one that itself has new relevant properties, like being a reasonably universal solvent, and having an unusual latent heat capacity, that are very relevant to explaining chemistry and even life itself.

    So emergence is all about a collective mode of organisation becoming a universalised property. And it is "a property" - something that justifies "more as different" - from the point of view of the further complexity of which it becomes the generalised platform.

    In a weakly emergent way - a supervenient way - water is just water. It is nothing more interesting than a form of organisation where an integrative force has taken over from a previously differentiating one. I mean water doesn't even seem an unpredictable surprise if you know that the same H2O molecules have both a kinetic energy and a van der Waals attraction as properties. We ought to be able to calculate "wateriness" from first principles knowledge of what was already lurking in the background - a suppressed integrative urge.

    But then water, once it forms, becomes a generalised substrate that reveals it itself to have unpredictable properties - like being just right as a medium for complex organic chemistry and life. Higher level theories discover these properties in water. It takes further levels of context to give water these new measurable qualities. The emergence is essentially semiotic.

    This gets to one of my discomforts with Crowther's presentation (which I only skimmed through, I admit). As a hierarchy of emergence, it doesn't start from the simple and move towards the complex - the natural or systems way of thinking about emergence. Instead it confuses things by trying to stick to the emergence of the simple from the simple - the "simple" meaning whatever is cosmically and universally the most simple condition given the time since the Big Bang.

    Now this is a useful view. But it depends on accepting the reality of a thermodynamic direction to time. And of course, standard reductionist or mechanical physical models deal in laws that are fundamentally reversible or time-symmetric. They thus hardwire in a presumption of linearity. Going forwards and going backwards are two views of the same thing. There just is no room for the non-linearities that are these abrupt phase transitions, these sudden changes in state, when a collective mode spreads exponentially across a system to become a new universalised property.

    Mechanical models that wire in time-symmetry cannot see emergence for this reason. Which is why collective modes of behaviour seem so spooky or epiphenomenal - not properly physical, causal and real.

    In the big view, physics is working towards a directional understanding of a temporal cosmos. The Universe begins in a "pure" quantum state at the Big Bang. And it is headed towards a "pure" inverse of that state at the Heat Death. Everything will become quantum again - an undifferentiated sea of fluctuations - but the other way round. All that was as hot as possible will be as cold as possible. All that was as small as possible will be as large as possible.

    Complexity and classicality are thus something that arise in the middle of it all. It is rather like a Benard cell.

    What many don't tell you is that a Benard cell only appears briefly. You have to keep the oil in the pan at precisely the right "boiling" point to see a simple pattern of convection currents. Keep heating and the hexagons break up into turbulence.

    So simple global order is what you get at the edge of chaos. The starting of a flip, the beginnings of an inversion, the middle of the change. It is the first big fluctuation that heralds the descent into that kind of fluctuation erupting fractally over all available physical scales.

    Again, EFTs don't really capture this. They do describe fluctuations in the infinite limit. So they do describe the world that has gone to maximum fractal turbulence and now looks - if we could stand outside it - to be a flat and simple surface. A platform with universal properties that is now suitable for the next level of more complex hierarchical organisation, based on the further use of those properties.

    So EFT thinking is good for accounting how the quantum realm becomes thermodynamically cohered at a certain physical scale and takes on the universal properties of the classical realm. And then in turn, biophysics is now investigating the nanoscale quasi-classical scale (of water as a solvent matrix) and showing how its hidden non-linearity is a resource of the semiotic properties that life needed to exist.

    So you have the sweeping view of physics where all the quantumness of the cosmos can get brushed under the carpet when things get large and cold enough for electrons and protons to be modelled in terms of individual particles with particular momenta and forces.

    The quasi-classical nature of the electron only becomes an issue again when electron behaviour has to be explained in the highly atypical scenario of a chilled metal lattice. Or when we roll forward to the end of time when quantum effects find a way to decay all matter back to cosmic radiation.

    And then biology has to get interested in the particular and atypical scenario that is the quasi-classical scale of water. Life depends on the fact that it can insert itself into the zone of criticality, or the edge of chaos, where things are not generally stable but generally poised on the edge of instability. The whole point now is that the EFT outcome - the hitting of a universalised limit - hasn't happened. Instead, life is playing around at the point where it is in-between - like a Benard cell. The collective mode is only being expressed in a fractured or fractal fashion. It is a bit quantum and a bit classical. And so the emergence of a property is this very in-betweenness - this lability, this instability, this duality, indeed this liveliness.

    So again, an important distinction that Crowther's presentation brushes over it seems.

    There is EFT emergence - where a system has just gone to the limit and universalised a collective mode as a system-wide homogenous property. A phase transition has happened and there is no going back.

    Well, reheating or depressurising the system can reverse its state. Water can re-evaporate. Particle accelerators can melt individual particles. But generally - if we are talking about the fundamental laws of a universe - then the direction of time itself locks in the transitions. EFTs seem the rule because they can safely presume symmetries have been broken, lines have been crossed, and there is no general way of ever going back. The general change is now dead and buried, safe to encode as an emergent law.

    Then there is this other kind of emergence that is becoming now really important for understanding complexity. Instead of wanting a world that is fundamentally dead and stable, it needs a world poised on the brink of change. It needs instability - as that then becomes the something that it itself can exist to control. If the world is poised for bifurcation - ready to go either way towards begin fully a gas or fully a liquid - then there is room to insert "intelligence" or semiotic mechanism in that gap and mine it in useful fashion.

    This was the dream of Maxwell's demon, by the way. And life - as negentropic or dissipative structure - can behave in that fashion, adding Benard cell like order that manages the transition from smooth flows to turbulent ones.

    So yes, emergence is a tricky subject as Crowther says. But I am against the idea that it is essentially pluralistic. Let's not leap straight from the one to the many.

    For me, a pan-semiotic metaphysics does bring all the strands of the story together. A triadic or hierarchical ontology makes complexity itself irreducible. And spontaneity or instability is part of that irreducible triad.

    So between the one and the many is the three-ness of actual hierarchical causality - the true systems of holistic view. This is where it is all leading as you muddle through "more is different" and the move away from an essentially dead and timeless, reductionist or constructivist, physics.
  • Is dark energy the outflow of dark matter from a universal black hole?
    Yep. So at best, this is an ongoing controversy. The consensus continues to advise caution.

    chief scientist from WMAP, Charles L. Bennett suggested coincidence and human psychology were involved, "I do think there is a bit of a psychological effect; people want to find unusual things."

    Sorry to be harsh, but the title of your OP suggests some half-baked thinking.

    "Is dark energy the outflow of dark matter from a universal black hole?"

    You might need to refine your terms. What is this dark matter such that its outflow would cause a general cosmic acceleration rather than a localised gravitational deceleration?

    If it is powerful enough to account for "70% of the missing mass", why does its flow from one place to another create such a remarkably insignificant cosmic anisotropy?

    What is a universal black hole here? Supermassive black holes are located in places within the universe. It sounds as you may be wanting to make some kind of "we are trapped inside a white hole" story that explains cosmic dark energy acceleration ... with a faint anisotropy. But why would that generalised hole even have an anisotropy?

    If you can put all the bits of the puzzle together, that would be interesting. So far I'm not seeing a well-motivated thought at the back of your OP.

    I'd be happy enough to be proved wrong, of course.
  • Is dark energy the outflow of dark matter from a universal black hole?
    How is that particular claim bearing up?

    Thus, we conclude that there is no significant evidence for anomalous dipole anisotropy in the LSS....

    https://arxiv.org/pdf/1606.06751.pdf
  • Is dark energy the outflow of dark matter from a universal black hole?
    Nope.

    Whatever dark energy is, it would have to be distributed absolutely evenly across every point of space (to match with the astronomical observations that identified its existence as a faint repulsive pressure present in the fabric of the void itself).

    Respectfully, the idea of "human potential" is so tainted with economic ideology that there's hardly any way of conceiving of what human potential might actually be independent of it.darthbarracuda

    That is a bit defeatest. The very fact that we can see we have allowed the economic machine to take over our lives is already the start of imagining what could be different. And we have plenty of folk trying to invent a better world right now.

  • How the idea of human potential is thrown around
    but we aren't indifferent to life as living itself requires axiological assessments,schopenhauer1

    Well yes. And through our actions we can make choices too.

    So why would we make a general choice of being a pessimist rather than an optimist? That is the issue here.

    You are saying there is no other sane choice but pessimism. Our optimistic pursuits lack "reality" for some reason. And it is at this point that a whole bunch of contradictions appear in your argument.

    Though the metaphysical claim might be true....schopenhauer1

    Well you just said that nature is indifferent. Hence neutral. So any valuing is ours.

    Now you have to explain why we then have no choice about that valuing. Or why a positive valuing is "secretly faking it" ... as a metaphysical truth.

    Bear in mind that optimism doesn't have to pretend everything is always wonderful. Just that goals are good and their satisfaction a possibility. And the naturalism I advocate is not even an optimism opposed to your pessimism. I am saying that nature does have preferences which shape us. If we want to locate meaningfulness, there is a larger story.

    So whichever way your argument leads you, it winds up in a contradiction. Either pessimism is a free human choice, and so optimism is the more sane option. Or else the world is really some way, and we ought to recognise that - and at worst, the world is only indifferent on your own admission.

    I can see you want to arrive at the naturalistic argument that we have evolved to be miserable. Whether by accident or design, we are just trapped in a state of being self-aware of a life that can only be dominated by suffering and pointlessness.

    But while that is indeed how many people may feel, it has to be stacked up against the psychological evidence. And the evidence says there are ways out of the trap. It just doesn't have the universality you want to claim. And from there, the ethical obligation is on you to make an effort, not wallow in misery and build a philosophy around bringing everyone else down to the same level.

    Indeed it is important to me, but no one has to live up to being a perfect pessimist ideal.schopenhauer1

    So why do you suffer in public and not in silence? What is the point of arguing your case so doggedly?

    Is it about convincing yourself? Is it in fact evidence of how our identities are socially constructed through our interactions and so you need the Pollyannas to give sharp definition to your own choice about a worldview?

    It sounds like you are saying either that "we must contribute to the system which created us" or "the system will provide the tools for living a happy life", then I think you are being naively dismissive of the situation.schopenhauer1

    If you present me as saying such naiveties, then yes, I certainly sound naively dismissive.

    But that's not what I said.

    You are so ready to frame my thoughts with your own construction of Enlightenment "isolating of humans from cosmos/god" and Romanticism's "rebellion of the individualistic human hero"...schopenhauer1

    Thanks for the credit. But this Enlightenment vs Romanticism is a well-advertised and self-proclaimed opposition in modern Western culture.

    I mean it's been defining what's cool, and what's not, since cool got invented. ;)

    Unless you really fully try to internalize the idea of "vicious absurdity" and the awareness of this, then it will be lost.schopenhauer1

    So we are back to your self-contradiction on the issue of whether you are speaking of nature or individual belief.

    Why would I want to "fully internalise" an attitude that is either a) not metaphysically real, or b) not subjectively ideal?

    What is this flourishing you speak of? It sounds a bit... Romantic!schopenhauer1

    I agree. But I could talk more dryly of how it would cash out in measurable and naturalistic psychological models.

    It is just that given you are speaking in the language of Romanticism here, it is useful to remind that even Romanticism recognises there are alternatives to believing life is one great unflushed toilet of woe.

    We are trapped with our own survival, trapped with our own maintenance, trapped with our own pursuing of X, Y, or Z avenues to what we think to be happiness. By framing it as "opportunities", the fact that it could never not be the case, was glossed over.schopenhauer1

    Trapped in being alive, hey? How utterly ghastly! Forever condemned to the hedonic treadmill.

    Columnar basaltT Clark

    Nice. Cooling causes contraction. Hexagonal cracking expresses the outcome which distributes the effort of rupture in the most symmetric or general fashion possible. The highest number of the smallest sides - given the cooling is slow enough, the liquid even enough, not to insert any local preferences into the story.
  • More Is Different
    Likewise, Crowther provides an examples of relative independence between pairs of domains that are both being governed by quantum mechanics.Pierre-Normand

    [Apologies. This is a bit roundabout as an actual response, but I started so I finished...]

    The philosophical tension here would seem to be the issue of how closely do our models of the world match the actuality of the world. And - in the name of pragmatic efficiency - would they even want to mirror that actuality? Does the map need to be like the territory, or is the whole point that it is not, which is why you can fold it up and stick it in your back pocket?

    But I would argue that our hierarchical approach to scientific modelling - starting off with the "fundamental" and building our way up to the messy complexity of actual reality - does deeply mirror reality in being about symmetries (a generalised lack of constraints) and symmetry-breaking (the addition or emergence of constraints).

    And then a further wrinkle, symmetry-breaking itself halts - and forms a hierarchical level - when it reaches an equilibrium condition. A new symmetry emerges when - as in an ideal gas - differences no longer make a difference. Macroscale order rules once the internals of the system are reduced to a statistical noise so far as the world is concerned.

    This is why more can be ontically different. The internal parts that construct the system have lost any power to disturb the general state of the system. As an equilibrium balance, its fluctuations don't count. And so now - when nature goes searching for symmetries to break, and we go searching for breakings to describe - it is the macrostate that forms the new hierarchical level, the new platform, for any breaking.

    That is a roundabout way of getting at the fundamentality of quantum mechanics. QM is a highly general view that includes "everything" by removing every symmetry-breaking and just talking nakedly about the statistics of fluctuations or individuations. It forms a ground zero at the point where indeterminism itself is constrained to produce determinism.

    So it arises from considering what could be the barest kind of intelligibility imposed on an unorganised possibility. And it discovers that any definite answer, any act of particularisation, must have the dialectical or complementary form of a dichotomy. To ask a symmetry-breaking question of nature, it must be posed as the either/or of two polar limits.

    This is just a principle of logic. To be A with complete definiteness, you have to be not not-A. And the quantum issue is you can't ask both questions - the questions being diametrically opposed - at the same time. Hence you can ask about location, but then you must lose sight of the complementary thing of momentum. The duality is baked in by the complementary nature of the questions you must ask to pin something down in a particular fashion when its existence is itself relative to the context of these two limits that must be "far out of each other's sight" to be real themselves.

    So quantumness itself arises due to the requirements of contextuality or holism. For even a fluctuation to have counterfactual definiteness, it must be placed relative to a context. And the barest context is already an asymmetry - a broken symmetry - in being formed by dichotomous boundary conditions. It has to be "world" that is described by logically complementary limits to being.

    So while reductionism/constructionism is based on the maths of bottom-up addition or summation, at the heart of holism is the maths of reciprocal or inverse relations. A-ness is defined in terms of its lack of not-A-ness. And not-A-ness in turn is defined by its lack of A-ness.

    To be located is to lack momentum. To have momentum is to lack location. Each stands as the other's ground of measurement. And as a reciprocal relation, that yields the uncertain curve. Shrinking the uncertainty concerning one leads to a matching increase in the uncertainty of the other.

    Anyway, our notion of the quantum arises by asking the deep question of what would the most general symmetry-breaking look like? And logic tells us that it is the bare reciprocal. It would have to be a world where the question was being posed in terms of the most fundamental complementary pair of properties. Dialectics would rule.

    So quantum mechanics describes that bare state. Well, it is not completely bare as QM has to presume a backdrop dimension of time which can make the simultaneity of the question-asking a thing. If the most global logical constraint is we don't get to ask two opposed question in the one act of measurement, then there has to be a passage of time to underpin that.

    A theory of everything, a theory of quantum gravity, of course hopes to get past that and show that time too is an emergent phenomenon of some kind.

    But that is what quantum theory does. It sets a baseline on intelligible existence. It is the minimal view that arises when we start not with some reductionist view of existence as a brute state, but a view of existence as a self-organising semiotic process of inquiry. If anything is to have definite existence, it would have to start with the dichotomy that is its boundaries. The symmetry-breaking kind of has to exist before the symmetry it breaks.

    This is an argument for strong holism, then. Or ontic structural realism. It is pretty Platonic in fact. A bootstrapping ontology. It says that it is the possibility of being organised that produces the material needed to construct the organisation. So not just "more is different", but it is the more that differentiates.

    Finally getting back around to the examples like phonons and superconductivity, science then adds further mathematical or Platonic structure to this fundamental quantum generality.

    What condensed matter phenomena, like phonons, demonstrate is that nature, at the quantum level, does not distinguish between solitary and collective excitations. It is not a fundamental fact that matter has to be atomistic. It is a more fundamental fact that matter has to have organised form. What makes the difference is the "shape" of the excitation, not the "number of parts" it seems to be composed of.

    So collective excitations of matter can have exactly the same quantum weirdness as individual particles. Nature sees no essential difference - as the complementarity of any fundamental "question asking" is the thing. Individuation is individuation. And QM is the general rules of the most primal possible acts of individuation.

    To break nature's indifference to fundamental level "excitations of a field", the world has to cool and expand. Bosons must become actually different to fermions in their statistics because something happens to break the symmetry of their spin and expose a handedness or chirality that adds a new level of anti-symmetric possibility. Once left looks different from right, another level of structure can arise as there is now a solid basis for a constraint that differentiates one vanilla excitation from another.

    Getting back to how closely our models of reality actually match that reality, I think what I have shown is that the bottom-up constructive view is really the view of things which is pretty much exactly back to front. It works because it is the formal inverse of "what is really going on".

    Holism is then more correct as it says form conjures matter into being. Reality bootstraps because there are mathematical-strength regularities it can't escape. Quantum mechanics is our picture of the first step at which this inevitable organisation - the one that is forced on indeterminate possibility by the very nature of a determining question - arises. And once that game has started, more specific constraining questions can follow. You get the cascade of further symmetry breakings which produce all the quantum particles of the Standard Model for a start.

    This is the thesis of Ontic Structural Realism. It was vogue as the bootstrap model - Chew's S-matrix model - of 1960s. John Wheeler said it nicely in his "it from bit" papers. The quantum reconstruction and quantum information approaches are reviving it currently.

    But still, I admit there is a problem. Even a completely formalist and logicist approach - one that says it is constraints all the way down to the bottom - has to grant some reality to materiality somewhere.

    Ontic Structural Realism or a Theory of Everything can shrink the notion of a bare action - a primal material/efficient cause - to practical invisibility. But a complete metaphysics still would want to say something about this complementary aspect of reality.

    Once holism has explained everything in terms of the constraints on fluctuations, there will still be the fluctuation itself to be explained.

    (Even if - as in the theory of spontaneous symmetry breaking - "anything" would start the tipping. A pencil will not stay balanced on its tip forever because anything and everything could shake it. And so a primal fluctuation would have no particular nature that had a "constructive" impact on the world it happened to produce. The mystery of the first fluctuation would become the least kind of possible mystery on that argument.)
  • An attempt to clarify my thoughts about metaphysics
    This is what really helped me in the Anderson paper - the discussion of reductionist vs. constructionist views.T Clark

    Yep. Reductionism can mean two different things.

    All modelling involves a reduction of a world to a model. So even holism is a reduction of the lived, messy complexity of the world to the abstracted simplicity of a model.

    But then holism is opposed to reductionism as reductionism is about bottom up construction, and holism adds the other countering thing of top down constraint.

    In reductionism, global organisation can emerge, but it is just a sum of all the parts. Nothing new of different arises. We might describe the global organisation with higher level macro laws. But in principle, the real explanation is all the detailed mechanics going on down at the base level.

    It is like freewill. It can’t be real - according to bottom up construction - as ultimately it is the result of a whole mass of completely deterministic atomic actions.

    But holism - as argued with mathematical clarity in hierarchy theory and cybernetics - says global organisation is a real level of causation as it has the power to bear down and shape the very parts making the whole.

    The world on the microscale is actually pretty irregular, indeterminate, unconstrained. Global order then arises by constraining those parts so they are simplified and regularised in a way that makes them all fit.

    You can think of a bee honeycomb. To squish a whole lot of wax tubes together, they must become hexagons. Maybe they could be all sorts of flattened shapes in principle. Triangular, octagonal, some kind of irregular never repeated lattice like your Mayan stone wall. But through the principle of least action, the regularity of a hexagonal pattern is the simplest way to tile that space.

    And hexagonal patterns are what we see emerging in the classic examples of self organising chaos, or dissipative structure, like the hexagonal convection currents of Benard cells -https://en.m.wikipedia.org/wiki/Rayleigh–Bénard_convection

    So more is different gets at this constraints based view. Hierarchical organisation develops because higher levels can simplify the world enough to shape the parts, regular and numerous, needed to construct them.

    It is cybernetic feedback. The system emerges from the noise as it tunes into its own grounding simplicity or regularity.
  • An attempt to clarify my thoughts about metaphysics
    So there's a collision between the traditionalist understanding and the Enlightenment mentality - this is what arguably underlies the 'culture wars'.Wayfarer

    So Aristotle did argue against atomism and in favour of a full "four causes" systems ontology. And atomism then made its roaring return as Enlightenment science.

    In terms of metaphysics, that was its own culture war. And Newtonian physics was seen to defeat Aristotelian physics - for the time being at least.

    But theistic metaphysics was its own dualistic thing. It stood against Aristotelian hylomorphism and immanence to bring in a transcendent and immaterial "mind". It was Platonic. So that led to the culture war that was not holism vs reductionism, but the Enlightenment vs Romanticism.

    Of course, if we are talking "traditional", then animism would be the original generic metaphysics. And the general materialism of Ancient Greek philosophy - coupled in uncertain fashion to the shock that mathematics could have an axiomatic basis - was the initial culture war against that.

    Step back and you can see the bigger story is of metaphysics finding it always wants to split in two. Some, indeed most, then take this as a sign it should be utterly split - resulting in a war. Some, always a minority, see that the split itself is what the holism of the metaphysics needs to embrace.

    So that is where the "meta-cultural war" takes place. Between the reductionists who are happy with opposed worlds, and their opposing world-views, and the holists who see division or symmetry-breaking as the creative step that produces a world in the first place. It takes yin and yang to tango. :)
  • An attempt to clarify my thoughts about metaphysics
    I doubt any biologist thinks of herself as practicing a branch of physics.T Clark

    Yes and no. Biology is my training. And I've seen it become normal to think of life as an essentially thermodynamic phenomenon.

    So back in the 1960s, life would have been seen as a chemical phenomenon. There was a reason organic chemistry was pretty mandatory. Biology 101 focused rather a lot on metabolic equations.

    Schrodinger's What is Life? was famous for spelling out that biology was in fact really about dissipative structure. The duo of negentropic order and the entropy it can produce.

    And this was good for the biologist's ego. It said not only was biology well-founded on deep cosmic principles, but biology was showing physics needed re-writing in a substantial fashion. Biology - because it understood this new nexus of information and dynamics - was the "larger view".

    So physics was really a simpler and less complex branch of biology, if you like. ;)
  • Space and Time, Proteins and Politics
    The philosophical relevance of this is that, when it comes to protein folding, space and time carry information, or rather, spacing and timing, specific geometries and specific timings have effects that cannot be 'read off' primary structure alone. Another way to put this is that spacing and timing are material: they are not idealized 'forms', but forces in their own regard, worldly 'contents'.StreetlightX

    So this is arguing a constraints-based or pan-semiotic view. But it wants to reject the reality of forms and talk about the reality of materiality.

    I would instead argue for the complementarity of the two. A systems approach would see each as equally real in their own way. And progress would be making that explicit in the scientific modelling of the situation.

    This was of course exactly what Pattee (Rosen's colleague) did with his epistemic cut approach to protein folding in particular. It is why the kind of biophysics described by Hoffman is so significant. We can see how life is the semiotic combo of information and dynamics, or formal cause and material cause. With a new understanding of the biophysics of the quasi-classical nanoscale, we can even see how biological information arises because the differences between kinds of material entropies disappears. Materiality can be regulated because it cost essentially nothing to switch it from one track to the other. Materiality becomes programmable.

    And this is a fact about spatio-temporality. It is due to there being a symmetry-breaking transition between a quantum state of materiality and a classical one at a certain distance and energy scale.

    So Kant is a bit irrelevant. He was only thinking of the classical conception of materiality that seems necessary - as an informational constraint - to make the world appear comprehensible to the senses. And that was an essentially "dead" framework. It reflected the Newtonian view of time and space as a backdrop a-causal frame.

    We already know from quantum theory that even spacetime is "lively" - observer-dependent in some important fashion. And this essentially informational view is being cashed out through holography and dissipative structure theory. The backdrop is causally involved in its own creation. Physics is arriving at the pan-semiotic view argued by Peirce.

    So yes. Information is alive and active everywhere in the Universe. But at the same time, the Universe has a hierarchical organisation of constraints. You can't just simply reject a global backdrop view and replace it by some story of absolute local contingency. A bricolage. That is leaping from one extreme to the other.

    The pan-semiotic approach, the holographic approach, the hierarchy theory approach, the infodynamic approach, are all ways of saying the same thing. Reality is an emergent equilibrium balance of its own internally opposed tendencies. It is formed by its dichotomous actions - in particular, the tension between global integration and local differentiation.

    So a globalised view - one that sees space and time as a dispassionate or a-causal container - is not the sole story. But nor will any completely local and contingent view - one that invokes an infinite variety of particular individuated causes - be either.

    The art of telling the story of existence lies in seeing how at every scale of being it is expressing the balancing of its formative tensions.

    And that too is a metaphysics with its political implications of course. :)
