@Wayfarer @javra So I've now taken some time aside after finishing
Metaphors We Live By from George Lakoff & Mark Johnson,
The Philosophical Impact of Contemporary Physics by Milic Capek, and an article titled
Naturalism, Quietism, and the Threat to Philosophy by Thomas J. Spiegel & Schwabe Verlag. I've also consulted some articles from the Stanford Encyclopedia of Philosophy and also some articles from the pseudoscientific paper posting hotspot called
viXra.org. If that looks familiar, yes, its just the rather more heavily relaxed and non-mainstream equivalent of
arXiv.org. I've decided to jump on giving a summary of what I've learned so as to hopefully generate novel discussion or questioning. Though, I'm doubtful I will do all this exquisite work any profound justice. This will be long and for that I apologize.
Something that underlies all these articles from the non-Mainstream to these dissident philosophical perspectives is a clear feeling of disenfranchisement from the establishment. There is something that is lacking among these 'ivory towers' which misses the core point of why one philosophizes to begin with, how one constructs scientific explanations, what it means to be scientific, or what deserves to be called a 'fact'. The dramatic displays of scientific rigor and success in documentaries or interviews is seen as increasingly suspect. Something to be ripped a part from analyzing the ambiguities of the language used and show how their own layman speech betrays them intellectually speaking. Each of the works listed explicitly above attempt to synthesize a solution, as is always done, to the perennial conflict of old.
--------
In
The Philosophical Impact of Contemporary Physics this message is front and center throughout the entirety of the work as Milic emphasizes the
non-visual nature of how one can come to understand nature without the same perennial errors of those who came before. Such errors revolving around identity, the spatialized language with regards to time, the supremacy of the
corpuscular-kinetic modeling of phenomena, the reign of determinism, certain properties of space, and an inherent splitting of nature into primary/secondary qualities.
A key point being the 'subconscious' element of Classical thinking which pervades all of modern physics despite their claims to the contrary. Even in antiquity, the attempts to circumvent perennial issues were rather devoid of rational teeth because the visual thinking they used had them imported in to begin with. An example of this is in the responses to the Eleatic problem of change and Zeno's arrow paradox. I.E. how can something change/move if its only ever composed stage wise of unchanging/un-moving instants? The mathematicians/theoretical physicist solution to this, in line with the Achilles tortoise paradox, ignores the perennial issue at its heart for a purely computational solution in terms of real analysis or limits. However, the usual solution to this from esoteric philosophies of old usually meant abandoning 'instants of time' for 'atomic intervals of time'. This, however, didn't deal directly with removing instants from our thinking as an 'interval' begs the question of a beginning and an end. Those edges being then instants in their own right even if only realized as limits. Further, this doesn't seem to have solved the perennial problem of change as we've rather substituted instantaneous moments for extended unchanging moments thereby still committing us to some peculiar view of nature in which change is. . . illusory or some purely mental phenomenon.
This is because the analogies that one visually conceives of when thinking of time itself, or space/causality/matter/motion, are fundamentally static in nature. Such as a block conception of time that views it pictorially as a collection of instantaneous NOW slices all stacked on top of each other similar to projector slides. That or put into analogy with a film strip whereby the change we perceive is, by the analogy itself, tricking us into thinking it's illusory as the real world doesn't yield true qualitative change but is unchanging fundamentally. I.E. its our consciousness that snakes up our worldline but not do to any 'internal' change of the worldline itself.
The Aristotelian notion of 'gunk' or matter that is not atomic but infinitely divisible is not deemed utterly irrational but rather stripped of much rationale to begin with as the change in size, weight, mass, momentum, energy, heat, or any other qualitative change is found in the unchanged. Heat is not some irreducible qualitative element of nature but a side-effect of the re-distribution/collisional interaction of the unchanging atomic constituents of reality. Any change in volume is by virtue of its 'parts' the result of them being moved farther apart or squished together and not some inherent qualitative change of the property of volume it possesses.
This idea of getting to the unchanged or fundamental then leads to a similar abstracted version of this which is the idea of looking for fundamental particles in nature. Even when Aether's were proposed by their originators to be 'fluidic' and a return to Aristotle's qualities in a sense they were then contradicted by those same physicists claiming this Aether actually had atomic parts. The only difference between this new Aether and the atomism before being the mere sheer number of atoms postulated. This thinking sinking deep into seeing phenomenon such as the Lorentzian contracted of electrons as not indicating qualitative change of fundamental elements but rather that our models indicate that the electron is itself not fundamental.
There must be some more fundamental truly unchanging parts which explain how this electron gained or lost its volume! As the admittance of qualitative change in things would seem as if we've postulated the acceptance of 'something from nothing'. Whatever it is that atoms possess and what they are is unable to be changed including their shape or internal properties. In this sense, even if we attempted to undo the Classical biases of before by adopting a 'fluidic' Aether we'd still have to deal with the skepticism of others subconsciously that we have rejected the dictum
ex nihilo, nihil fit.
Space is without boundary and fundamentally three-dimensional in nature. It being most importantly homogeneous, isotropic, casually inert, continuous, and
Euclidean. There are esoteric philosophies which grabble with the Aristotelian idea of there being no space outside his spheres by using this pictorial imagery of throwing a spear or extending ones' arms beyond this outer most sphere. You can always imagine a more zoomed out view of an object of it sitting in a further, vaster, void and anything moving away from this thing still being 'in space'. The notion of a boundary of space, a hole, or a non-Euclidean nature being virtually ruled out fundamentally by such visual biases.
Further, space is itself not able to be influenced by physical things nor influence them as its core role is some vague logical differentiation of qualitatively similar atoms. It can be zoomed out as far as one pleases or zoomed in and similar to nesting dolls we can find universes within universes that themselves look eerily similar but just smaller. Ergo, the popular Rutherford analogy of an atom in complete similarity to our solar system. This is also dubbed the
relativity of magnitude rather than mere continuity. Finally, space may serve the role of differentiating qualitatively similar atoms but its only matter itself that serves to distinguish a part of space from another and not space itself. Only the relative variation of atoms by separation and their motions serving to distinguish one place from another.
Another note is given about how this Classical line of thinking doesn't allow for one to leave the dichotomy of fatalistic determinism or random indeterminism. I.E. when one thinks of different frames of a universal 'movie' its either fully determined how it will all play out before you hit play or you could put in one frame after another with each being fundamentally disjoint/disconnected. The only reason then that this momentary blinking present has any sense of continuity or coherency being some great miracle of nature.
How does one circumvent this all? What interpretation should one then give special/general relativity which isn't one characteristic of a 'block' spacetime? What the true interpretation of the Heisenberg uncertainty principle?
Well, its to subvert everything brought about in the entire corpuscular-kinetic picture of the world including the usage of pictorial language. While the Classical picture separated out space from matter the lesson to be learned from General Relativity is one in which the two are rather actually conjoined. This means it becomes rather vague and uncertain fundamentally where space ends or matter begins. It also means to regard space as not homogeneous in the sense that its non-Euclidean of a certain sort. To regard it as discontinuous on some fundamental level similar to theories of quantum gravity which atomize space BUT without the problematic visual biases here so perhaps particles could in some sense be 'gaps' in space. Given matter is seen as another side of the coin of spacetime then this means it's not casually inert anymore but rather actively plays its own role.
The biggest change being to institute, via inspiring work from Bergson or Whitehead, a fundamental notion of change/time that is in no way reducible to the unchanging. Its an acknowledgement of the irrationality of such a pursuit and an admittance of what needs to be done. Here is where a clarification is in order as to how one should interpret Special Relativity and its relativity of simultaneity. Contrary to wide-spread belief there is actually nothing really shocking about what SR has to bring to the table as what becomes relativized in the theory. These being temporal measurements we ascribe intervals of time and casually un-related events.
Events which are casually related cannot be made to happen in a different causal order by frame changes. They are in fact topologically invariant and so while it might be relative how long we ascribe metrical units. . . the 'flow of time' is in fact not so relative. The 'movement' from the 'future' to the 'past' is left untouched.
Our notion of an instantaneous NOW is left in shambles without instantaneous actions at a distance and with that our notion of NOW is inexorably intertwined with HERE. I.E. there is now only the HERE-NOW and the THERE-THEN where the notion of THERE-NOW is left in an undetermined or vague sense. Asking such a question as what its like THERE-NOW being as nonsense as saying we are interacting with them right here when in fact we are not.
Despite the claims to the contrary that one either accept a spatialized block interpretation of SR or some highly solipsistic presentist strawman we should admit to the best of both worlds. That the future is left indeterminate or in Aristotle's words filled with potentiality which awaits actualization in the present to then be shrugged off into the determinate past. A concept of time that is 'thick' and begets true 'novelty' in nature as the indeterminate future filled with potentialities talks to the present as the present does to the past in a strongly casual manner but one which allows for true variation in the world. One which cements the irreducibility of the arrow of time and scoffs at the idea of eternal recurrence.
A cohesive and beautiful orchestra of distinct voices which form a coherent whole yet remain distinct. Notes which lose their reality if you analyze them in too short an interval of time and whose reality isn't really so unless you hear their full beat. This usage of musical metaphor being what Milic and those he credits with process philosophizing use rather than pictorial or spatialized ones in getting at these esoteric notions of reality.
There is another characteristic of the approach here which is to regard quantitative ascriptions as something required by our need to manipulate nature but ill-equipped to deal with nature on its own terms. We yearn for boundaries, clear separations, static states, patterns, continuity, etc. However, it seems that nature begets both this quantitative view and the visual analogies we use which force such concepts on us to begin with. Our quantitative manipulations may be useful but their universality is itself the illusion.
What language do we use then? How can we un-visualize our language for the purposes of physics which doesn't fall into mere mathematical symbolism?
--------
It's not that quantification is either simply abstract or entertaining, but that it's exact. Insofar as you can quantify, you can predict and control. One of the prime factors in the success of science is the increasing scope and accuracy of measurement. In Plato there is recognition of the exact nature of arithmetical proofs, which are contrasted with value judgements about the sensory domain, hence dianoia, arithmetical reasoning, being judged higher that sense experience; when you know an arithmetic proof, you know it with perfect clarity and without reference to anything else. The Galileo quote you refer to was 'nature is written in mathematical language, and its characters are triangles, circles and other geometric figures, without which it is impossible to humanly understand a word; without these, one is wandering in a dark labyrinth.' Hence the fundamental significance of quantitative data in science, and the division I mentioned in the earlier post between primary (measurable) and secondary (subjective) attributes. — Wayfarer
I would feel then that in line with Milic the only direction to go would be to one of a highly metaphorical or esoteric sense of philosophizing which also acknowledges the fallibility of such an approach or its limitations. That way we, as Milic feared, neither fall into some esoteric animisim of old or be accused of seeing math in nature (panmatheism)
--------
Are you equating these models to what science in essence is? If you are, you then seem to disagree with my appraisals of what empirical science consists of. No biggie, but I am curious. — javra
More playing devils advocate here. Course, its not too far from the Stanford Encyclopedia article's on science to think that true scientific explanation is to be found in visual analogical modeling. Especially given most of scientific theorizing is merely mathematical modeling, visual analogical modeling, and metaphorical prose. Its just a question of intuitive primacy as to which of these aspects should be emphasized more and what we think an explanation amounts to philosophically speaking.
Math for example makes for a rather good description of nature. . . but an explanation?
When I stated that the data remains, I was addressing the verifiable results which are for example obtained from the delayed-choice quantum erasure experiment—which pose serious problems either for classical notions of causation, for classical notions of physical identity, or else for both. And I so far understand both these classical notions to be requisite for any mechanistic account, even more so for any "highly mechanistic" account of the world in scientific philosophy. — javra
So did GR. . . and Quantum mechanics. . . or any physics which has come before. Experiments do not decide interpretations in any determinate sense but rather can remain stubborn biases without proof or dis-proof or in lieu of apparent dis-proof. Take the idea of talk about fundamental particles or constituents of reality which is a stubborn assumption of a Classical mentality. No amount of scientific argument or experimentation could settle the rationality of such a doctrine as either the particle is split showcasing its not fundamental, its postulated it is fundamental if it meets certain requirements, or if those requirements aren't met then its assumed to be not fundamental. ITS NOT TESTABLE!
Again, taking the example of the Lorentzian contraction of an electron. This doesn't have to imply a disproof of the corpuscular model but rather a proof of its non-fundamentality model-wise.
You don't falsify the corpuscular-kinetic biases of old and also don't falsify the conception of energy conservation. You don't falsify Classical mechanics or prove an indeterminate reality from Heisenberg's uncertainty principle. Its only on higher order philosophical intuitions that this is done.
The replicable data obtained from this experiment, then, will yet need to be accurately accounted for regardless of the implemented models, mathematical or otherwise; regardless of the philosophical explanations which inevitably make use of metaphysical assumptions regarding the nature of space, time, and causality; and so forth. As to the mathematics involved, it is directly related to the data—such that were the mathematical system implemented to be contradicted by empirical test, it would hold no scientific value. Here, for example, thinking of the classic tests which were accordant to Einstein's theory of general relativity; were these test to have not so been, the mathematical system/theory would not have held water. (Related to this, because string-theory is currently not falsifiable via tests, this mathematical system is argued by some to be non-scientific—even if other speculate that M-theory can be further developed into a unified theory of physics.) At any rate, while explanations and models for the acquired data can change, the data nevertheless remains. — javra
Exactly, the
epicycles of the day and the things they model remain unchanged as they are correct by coincidence but if shown wrong then the math is MODIFIED to account for this. You may claim its not done so in the sense of curve fitting but its fitting nonetheless and this may be curve fitting which takes into account more than the data itself. Its still just theory fitting.
Math is ambivalent to interpretation and can beget ANY interpretation.
For example, does General relativity make gravity not a force? According to Einstein's field equations it does not but according to a mathematically equivalent version which predict all the same things, teleparallel gravity, its more akin to a force or a change of torsion rather than curvature. This is similar to how Newtonian gravitation can be geometrized into what is called Newton-Cartan gravity which removes the force from gravity to make it a part of the curvature of space mathematically speaking.
