    They are actually closely related. The kind of non-realism Gnomon expresses about position and momentum is the same kind of non-realism as in the non-realism / non-locality issue. I actually think the dichotomy of realism vs locality is a bit of a pointless dichotomy because you cannot really choose the non-realism option without an ontology that basically still looks as non-local as the non-local option... for the intents and purposes of commonsense anyway. You would [still] have to talk about non-separable states that exist over space which I would say is about as bizarre as the non-local option.

    The small and the great aren't two different things. You can never find the large without moving through the small if you imagine knowledge as feeling around inside an object. It really should work like a machine: take a particle out of the object and it acts thusly; connect it with the object again and it'sphysics must align with that of either the other particles or the whole. Or which is it? How does one define what a "thing" is, as if it is a number?

    there was already a fine answer to this problem that had been popular for millennia. Aristotle lays it out in the Posterior Analytics and other places. Science deals with per se predications, what is essential to things, not per accidens. This rules out organizing the sciences based on relation (or time/space) because these can involve and infinite number of predications and we cannot consider and infinite number of predicates in a finite time for the same reason that one cannot cross an infinite distance in a finite time at a finite speed. So there can be no science of "biology as studied by men named John" and no "chemistry inside the bodies of cats on the island of Iceland."Count Timothy von Icarus

    There is a biology of humanity since the laws wouldn't exist without that level of intelligence. Without consciousness itself the universe would be a world of a single thing just being, and moving, and being. Pure being. Imagine you lost your eyes. Suddenly youre plunged into darkness, forever.

    If the world wasn't in motion there could not be life. I know there is the block universe idea, but that's more on a metà level for me. Space and time can be understood separately. Space is where motion and the organic thrive. Time is what coordinates the future to the past. Say there is a wormhole: that would mean there are other spacial realities other than ours. If there are other time realities there could be backwards causation and time travel effects. That would be less within our emprical experience though. Even the wormhole is. Again, we know there is motion because there is love and life. Asking whether our senses perceive correctly, however, can indeed be a thorny question. To perceive is to "have before you"

    It seems to be a positive way to express the uncertainty of quantum physics. A particle can be either located in space (position), or measured for movement (momentum), but not both at the same time. Real things can be measured both ways, so what's wrong with quantum particles? Are they not things? Are they not real?Gnomon

    Well it’s not much of a problem per se because this only applies to very small stuff, not our day to day.

    This is something I've wondered about. Is it possible to have a scientific understanding of some aspect of the world without an ontology? Without a story about what is going on? This question comes up in the context of quantum mechanics. Is that the Copenhagen interpretation? Is that enough? If there is no way, even in theory, to verify or falsify the many worlds interpretation, does it even mean anything?T Clark

    The interpretations are just a way to explain the math which is air-tight. The story for science is to assume realism and an external world because otherwise science becomes pointless to perform.

    As I understand it, the question of non-realism vs. non-locality is completely different and completely separate from the question of position vs. momentum, i.e. the uncertainty principle.T Clark
    As I understood it, the question was "how can anything non-local (no measurable position) be real?" I guess it comes down to how you define "real". Some quantum physicists seemed to evade that real-vs-ideal question, by means of the "shut-up and calculate" approach. For example, Quantum Fields are defined as real because they have the potential for producing energy, even though the infinite "points" that make up the field are mathematical instead of material. Is Potential real, or ideal? :smile:


    Do Quantum fields describe reality or are reality?
    https://physics.stackexchange.com/questions/769217/do-quantum-fields-describe-reality-or-are-reality

    Nevertheless, quantum fields must be considered real, as they carry energy and have both calculable and measurable effects on the light and matter within the Universe.

    "The true being of a man is, on the contrary, his act; individuality is real in the deed, and a deed it is which cancels both the aspects of what is 'meant' or 'presumed' to be. In one aspect where what is 'presumed' or 'imagined' takes the form of a passive bodily being, individuality puts itself forward in action as the negative [dynamic] essence which only is so far as it cancels being. Then furthermore the act does away with the inexpressible of what self-conscious individuality really 'means'; in regard to such 'meaning', individuality is endlessly determining and determinable. This false infinite, this endless determining, is abolished in a completed act. The act is [nonetheless] something simply determinate, universal, to be grasped as an abstract, distinctive whole..."

    What's always funny to me is how the classical Newtonian view is held up as the paradigm of "common sense intuitions."

    Is it? It's sometimes claimed that classical mechanics "works perfectly" for medium sized objects, and that problems only show up at very large or very small scales.

    Except it doesn't. Right from the beginning gravity was an occult force acting at a distance, which in turn had to make "natural laws" active casual agents in the world "shoving the planets into their places like schoolboys" as Hegel puts it. The deficiencies of such a model of causation are well highlighted by Hume. Then electromagnetism added another occult force that didn't fit into the "everything is little billiard balls model."

    Nor could/has the mechanistic model, where the billiard ball is the paradigmatic example of all physical interactions, been able to explain life or consciousness, nor was it able to offer up theories of self-organization, except via a deficient view of organisms as simply intricate "clockwork." Nor, in it's classical forms, can it incorporate information and the successes of information theory. We have suggested a long hangover of "Cartesian anxiety," because the classical model required early modern thinkers to excise consciousness, ideas, and freedom from the "physical realm."

    I think the "anti-metaphysical movement's" greatest success has been to keep us stuck, frozen with a defunct 19th century metaphysics as the default, such that it becomes "common sense," to most through our education system. But surely it is cannot be "common sense" in any overarching sense, since it differs dramatically from the more organic-focused physics that dominated for two millennia prior to the creation of the classical model.

    Information reminds me of Kant and his spiritual-metaphysical-psychological-physiological take of space and time and how it interacts with the brain.

  • Count Timothy von Icarus

    It's an interesting question for sure. But against the "information requires consciousness," view we might consider the ways in which information theory informs the biology of algae, viruses, and protists, who I am not sure we want to count as "conscious," even if their behavior is certainly "goal-directed," or "teleonomic."

    Plus, if one buys into something like computational theory of mind (long the dominant paradigm in cognitive science) or integrated information theory, then it would seem that information has to come prior to consciousness (else we have a circular explanation).

    Of course, pancomputationalism is also very popular with physicists, and this would seem to cut the legs out of CTM, in that literally everything is a computer in some sense, making the brain's "being a computer" not much of an explanation of consciousness.

    There is another circularity here. Turing comes up with the Turing Machine model with human computers in mind. Back in his day a "computer" was a person you paid to do calculations. The model is based on what that person needs to do to calculate. The "states" of the Turing Machine are "states of mind" originally. So, we end up explaining consciousness (or all of physics) in terms of a concept whose most popular explanation has a sort of Cartesian homunculus right in the middle of its paradigmatic explanation.

    The Shannon-Weaver model of communications also (often) has an implicit Cartesian homunculus in the "destination" that understands any signal in many contexts as well.

    IDK, it's a tricky area. I think that the solution is likely to involve seeing that life, consciousness, and goal directedness are not binaries, but exist on a sliding scale (contrary opposition, not contradictory) and that semiotic relations need not involved an "interpreter" just an "interpretant" (e.g. a ribosome doesn't "read.")

    Which reminds me of a good quote on this sort of issue:


    If we could ask the medieval scientist 'Why, then, do
    you talk as if [inanimate objects like rocks had desires]?' he might (for he was always a dialectician) retort with the counter-question, 'But do you intend your language about laws and obedience any more literally than I intend mine about kindly enclyning? Do you really believe that a falling stone is aware of a directive issued to it by some legislator and feels either a moral or a prudential obligation to conform?' We should then have to admit that both ways of expressing are metaphorical. The odd thing is that ours is the more anthropomorphic of the two. To talk as if inanimate bodies had a homing instinct is to bring them no nearer to us than the pigeons; to talk as if they could ' obey laws' is to treat them like men and even like citizens.

    But though neither statement can be taken literally, it
    does not follow that it makes no difference which is used. On the imaginative and emotional level it makes a great difference whether, with the medievals, we project upon the universe our strivings and desires, or with the moderns, our police-system and our traffic regulations. The old language continually suggests a sort of continuity between merely physical events and our most spiritual aspirations.


    C.S. Lewis - The Discarded Image

    Of course, theology has had a lasting impact on scientism here, because the move from the universe as an organic whole to one defined by "laws" that are inscrutable, and some initial efficient cause, is not what you get when you simply "strip away superstition," but is rather Reformation theology, whose influence remains potent even in the hands of avowed atheists centuries later.

But does it make sense to extend backwards humanity, as a thought experiment, and think of it with no origin except the ever intermediate subject.

    If the world wasn't in motion there could not be life.Gregory

    I am not so sure if the world is in motion. Because when you say something is in motion, it is moving from and towards a direction i.e. from a to b, or b to a. The world doesn't seem to be moving in that way or physically in motion.

    However, there are changes in the world. The physical objects and life go through changes, and some are in motion. Both change and motion require space and time for their operations. We can see the changes and motions happening in front of us all the time. We can notice also the changes and motions taken place in the past by looking at the history of the world and life.

    The universe seems to be just a container for all the objects, life and events taking place, and then vanishing into the void. We don't know how large the universe is, how old it is, and even how it began. It has a few theories, but none seem to be the definite truth. The universe will always remain as the deepest mystery in which we are born, live and perish into. Is it real? What is real?

    Because, of course there is a problem, it's literally called the "Hard Problem of Conciousness," which cognitive scientists bring up all the time. It has not been "solved." Nor has a satisfactory explanation of emergence, or consensus on if it even really exists, been accepted by most scientists and philosophers. You can find entire academic tomes dedicated to emergence, and many (e.g. the Routledge Handbook) will have to spend hundreds of pages on articles dealing with vagaries and contradictory theories precisely because it isn't something that is "solved."

    Nor is "x is emergent" particularly explanatory or unproblematic. What does it mean for something to be "emergent?" Weak emergence as mere data compression, or strong emergence? (And does the latter require getting "something from nothing?" Does it make whatever emerges in some way "fundemental?")

    These are all questions scientists and philosophers are still exploring. See: https://plato.stanford.edu/entries/properties-emergent/

    When scientists work on these issues they end up having to do philosophy. There is no hard line between "philosophy of biology," and biology at any rate. "What is life?" or "are plant and animal species 'real?'" are questions biologists try to answer for instance.

    Philosophers sometimes err by straying into areas that they don't understand, but this is equally true for people who work in the natural sciences. E.g., Sapolsky put out an entire book on the "science" of free will, which flops back and forth between bigism and smallism as it suits his argument, and he seems to think that action must be "uncaused" to be free or that any self-determining process must break down into self-determining "parts." There are lots of scientific citations in the book (including lots of unreplicatable, highly questionable stuff, such as the "Lady Macbeth effect,") and he's a scientist, but it isn't good scientific/philosophical reasoning, more an ad hoc mashup of datapoints said to fit an unclear thesis.

    This is incredibly common in more theoretical scientific works because you often don't get taught about good argument in undergrad or grad programs in the sciences (at least I didn't). So a lot of popular science seems to mistake lining up an avalanche of citations and referring to how they could fit/be explained by theoretical these, for good argument. This is how you end up with multiple different people who claim to have "solved the Hard Problem" pushing incommensurate theories that nonetheless use all the same landmark studies as their datapoints.

    My quote had mentioned the language of "laws of nature." There is also a great deal of debate in the empirical sciences about how to think about these or how to think of causation more generally. There is not consensus here, nor any sort of "common sense," unproblematic definition of what the "laws of nature" are and how they work. And, like I said, it's a language inherited from a theological context and a certain vision of God; the early modern scientists who created our model didn't separate religion and science in the same way.
