You missed the point. I didn't refer to Aristotle as an authority on storage batteries, but as the guy who originally defined the terms "Potential" & "Actual"*1. Of course, Voltage is a measure of Energy, not energy per se. And the measurement is expressed as a ratio between Zero now and some Potential value in the future. A battery contains no Actual Energy, only Potential Energy*2. That's why you can touch both poles and not get shocked. Aristotle's definition, in terms of existence, is pertinent to the OP topic of Reality. :smile:Aristotle is probably not the best source, regarding the nature of batteries. Also the subject was potential energy. Voltage is not energy. — wonderer1
Sounds good to me. But how do you determine the accuracy of fit for a world model? Since many of the controversies on this forum revolve around the physical foundations of the world (e.g. matter particles vs mathematical fields) , I tend to rely on Quantum Physics as the most appropriate resource.Well, I find it to be a matter of skill in considering things, to be able to look at things from different perspectives, so I'm apt to apply the sort of modeling that seems most usefully accurate for what I am considering, whether that be particles, or fields, or whatever. It doesn't make much sense to call a model "Real" though. It makes more sense to me to consider the degree to which a model is accurate, and not confuse the model for that which is being modeled — wonderer1
Yes. Although my post contrasted Potential with Actual, and Real with Ideal, not Potential Energy with Reality, as you mis-construed it. For example, a AAA battery has a potential voltage of 1.5V, but until it's plugged into a complete circuit, that potential is not realized. Any potential thing or action is not yet real (i.e. not materialized), until actualized*1 in a system. Do you disagree with my list of opposites in this context? If so, in what sense is Potential real?*2.So potential energy is not real? — Banno
Are you accusing me of "dismantling the apparatus of physics"? Or merely of being "crass" enough to mention an alternative (non-mechanical) mechanism? Could you be more specific? Which "apparatus" am I tearing down? Newtonian Mechanics?*3 Actually, it was the pioneers of Quantum Theory who crassly deconstructed Newton's machine with "spooky action at a distance".But of course, you did not mean that. It would be crass for someone to suggest that we ought dismantle the apparatus of physics because it does not meet your exhortation. — Banno
Just as Space would not exist without Matter, Time would not exist without Change. They are two sides of the same coin. Which Einstein curiously labelled "space-time", as a four-dimensional continuum, not of Being, but of Potential. :smile:Time is a special dimension that only occurs in relation to change happening in space. If we take space away (all three dimensions) would time exist or would it be meaningless to talk of time in such a hypothetical situation? — simplyG
Thanks for the correction. I had never heard of Austin, before reading the Philosophy Now article. And my comments are based on the article, not from personal familiarity.J. L. Austin, you mean. Not to be confused with John Austin, the esteemed (by me) legal positivist. — Ciceronianus
Unfortunately, such a bureaucratic conceit would stifle the most creative philosophers. For example, I tried to read Whitehead's Process and Reality --- in which he conceived of a new school of Process Philosophy --- but found its novel technical terminology hard to follow. That's one reason I provide an extensive glossary & footnotes in my thesis and blog*1.It strikes me that if we're going to accuse philosophers of conceit, that accusation is more properly brought against those who disregard the meaning of a word, creating their own meaning for self-serving purposes. — Ciceronianus
To the contrary, I was distinguishing between Nature and Culture, not Nature and Reality. Nature got along for eons without Culture or Language, until artificial "human nature" -- in the last few ticks of Time -- began dominating natural Nature. Do you think humans are nothing-but Nature? In what sense is Culture or Language Real? Certainly not in the sense of this thread's topic, implying that Real is the opposite of Ideal, which is the exclusive purview of human thought, language & philosophy. :smile:But Language is the essence of human Culture, and hardly Real, in the sense of Natural*3. — Gnomon
You don't think we're part of nature? Or you think we're not real? — Ciceronianus
Thanks. I suspect that will applaud your succinct appraisal of my Synthetic assessment of Austin's Linguistic analysis of Philosophy's verbal non-sense about what's real & what's not. :smile:T.L. Austin — Gnomon
Hmm. — Banno
OK. What kind of philosophical world model, based on what kind of scientific evidence, are you willing to accept as Real? Is that less confusing --- or more? :smile:So, what kind of evidence are you willing to accept as Real : physical/material Objects, or mathematical/immaterial Fields? — Gnomon
You seem to be confusing evidence with ways of modeling things. Your question doesn't make much sense to me. — wonderer1
Yes. That was the point of my introductory remarks in the post. Since each "subset" is based on different axioms & assumptions, we need to specify which world-model of Reality we are arguing from. Failure to do that leads to fruitless talking-past-each-other on such general topics as Reality. Unfortunately, the tinted lenses of our partial worldviews are often taken to reveal the world as it really is. So, we are surprised when others don't see it as we do.It seems the word real has many meanings depending on which subset of philosophy you wish to answer it from. The empirical or the speculative metaphysical are equally correct and the issue only arises in under certain dualities for example is light a wave or a particle? The duality of light challenges the notion of reality by having the observer involved whereas in actuality light is both a wave and and a particle by behaving as such. — simplyG
Is it? I've never seen, tasted, or touched an electron. All I know about those invisible entities is the published interpretations of quantum physicists*1. 17th century physicists had no concept of an electron, but they imagined fundamental particles of matter, that everyone had agreed on since the 5th century BC*2. Besides, its properties depend on how you look at it*3. Is that a "literary" interpretation? Unlike the simple atoms of Classical Physics, quantum-scale particles are subject to various interpretations*4. Is that still "hard" Science, or is it "literary" Philosophy, or both? :smile:But I assume that no one would object to the "is," that everyone would agree that an electron is, at least, a something. Yes? No? — tim wood
In Science, what is Real & Physical & Actual is what is not Ideal or Imaginary or merely Potential. Yet in Philosophy, we don't concern ourselves with real things, but with imaginary ideas about things : i.e. hypotheses & theories & possibilities. Unfortunately, Quantum Science opened a worm-ridden can of rotten peaches, when it realized (pun) that the foundations of Reality are literally & physically Uncertain*1. That's what the Copenhagen interpretation asked sub-atomic scientists to believe, or else "just shut-up and calculate"*2.And how can you know that for real? — A Realist
For the purposes of this forum, Ideas are the non-things (non-stuff) that we argue about in threads such as this. And for the most part, Ideas are limited to a tiny clique in the universe, consisting mostly of the upright animals we label as homo sapiens ; implying that other animals are not wise enough to debate about the meaning of ideas. Hence, in the Real world, no questioning humans, no ideas, no philosophy ; just atoms whirling in the void. What makes ideas moot is their immaterial "substance". Material objects are seldom the topic of TPF threads. :smile:I do not know what an idea is, but I account them as existing and in a sense real. — tim wood
It's also the lack of material evidence for thingness, that limits Ideas to the central focus of philosophical forums, and only peripherally for scientific forums. The latter are supposedly reserved for those who "shut-up and calculate". And feckless philosophers are not welcome to blab on & on about Qualia which cannot be Quantified. :wink:Or the challenge: to exhibit as "stuff" any idea that requires a mind to have it - no mind, no idea. Or for anything, to exhibit conclusive evidence as to its existence as a thing. — tim wood
Gladly! The term "quantum" was introduced into the vocabulary of science to represent the aspects of reality that were assumed, by Classical Physics, to be continuous, but in sub-atomic experiments returned dis-continuous results. The quantum pioneers didn't describe those results in terms of Magic, but of "Nature exposed to our methods of questioning" (Heisenberg). In order to deal with both the continuous and the discrete nature of sub-atomic Nature, the pioneers re-introduced philosophical methods into empirical numerical science. That qualitative method of interpretation*1 had been banished centuries ago as too entangled with Religion & Magic. Quantum physics is unavoidably statistical, returning not absolute either/or answers but relative BothAnd percentages, :cool:Your use of "quantum" I could use some clarification on. That is, I think things happen, and of things that happen, they happen either for a reason (as caused in some way) or for no reason or because of magic. — tim wood
Feynman "did not know" what quantum duality meant, because he was looking for absolute Either/Or answers, not Einsteinian BothAnd relative approximations. His attitude of "shut-up and calculate" --- while avoiding the philosophical problem --- is what has allowed modern science to produce the 21st century technology, such as atomic bombs, cell phones, and Twitter gossip, that we enjoy today --- but would have seemed magical in the 17th century.That is, imho, the correct response to quantum weirdness is not to super-impose great edifices of additional weirdness as account, but rather instead to say, as with Feynman, it works but we don't know how. — tim wood
I view Mathematics as the meta-physical structure (inter-relationships, ratios, proportions) of the physical universe (objects, things). In other words, Mathematics is the Logic of Reality. In that case, the math (logic, design) is prior to the material implementation (stars, planets, plants, animals). Math doesn't "supersede" the matter, but it necessarily preceded the Big Bang execution of the program of Evolution that produces the Reality we see around us. Hence Math/Logic may be the abstract invisible essential ding an sich that makes concrete substantial things what they appear to be to our senses. :smile:Or is maths completely independent of the physical universe and it just so happens that some mathematics is good at describing some aspects of the physical universe and in fact supersedes it? — simplyG
Since I have no formal training in Philosophy, I won't presume to comment on the arcane discussion in the video, as it's mostly over my pointy little head. Instead, I'll merely note that the opposing worldviews, classified under relatively new labels of OOO or Speculative Realism versus Subjective Idealism, are extant on this forum under the more general & traditional categories of Materialism/Physicalism/Realism versus Metaphysicalism/Idealism.In Harman, the "essence" of an object is always "withdrawn" or "hidden" such that it cannot be interacted with. Therefore, it cannot be defined, but its influence is felt through its causative interactions with other objects, so we know there is an echo of "something" within the object that "Makes it that object" — schopenhauer1
My point was just to see if you were arguing from a well-thought-out personal worldview, or just parroting a party line (or template). For example, for all practical purposes (e.g. science & technology) I could be placed under the heading of "Materialist". But, for theoretical purposes (e.g. philosophy & ethics) I might fit better into the category of "Idealist". That's because the non-human material aspects of the world have no Ideas (words, concepts) for us to argue about : either it is, or it ain't.And that seems to me pretty clear in itself - is there something about it you did not understand that I could clarify? Why would you need a superfluous label, or template, to consider it? Or more simply, what's your point? — tim wood
Are you using Wittgenstein as an authority to justify an evasive non-position on a philosophical question? Does that side-step imply that you have no philosophical worldview, or just that you don't want to expose your subjective personal "template" to objective critical analysis? I too, am wary of being dismissively labeled, but it's a risk I'm willing to take, in the interest of refining my beliefs in the give & take of philosophy. Perhaps you would be willing to deny the labels that don't apply to you?Would you characterize the world model described above as "Materialism", or "Physicalism", or merely "Atheism"? No information, no patterns, no interrelationships, just atoms whirling in the void? — Gnomon
I wouldn't characterize it. I have a memory of something read that I think came from Wittgenstein, that all theories are templates placed over the world, and not to be mistaken for the world itself or how it works. And buying that, I have no urge to resort to templates - except of course when my human business requires me to. — tim wood
One interpretation of "politics" is "polarized people" : Lords vs Commons, Republican vs Democrat, us vs them ; friends vs enemies ; Good vs Evil ; our people (NAZI volk) vs aliens (Jews, etc). That rational (non-emotional) assessment sums up why I am literally apolitical. It's not that I have no interest in the issues being argued, but simply that I'm not prepared to choose-up sides and fight for my values. My personal values are multivalent, and are found on both sides of most either/or, two-value party lines.I’ve recently discovered this term “apolitical” and since political opinions are tied to values most of the time, I was wondering what an “apolitical” person without values would be like. It's obviously impossible for a human to completely lack values and political opinions, but what I mean is someone who would actively try to minimize/ignore them. — Skalidris
My two bits worth :Do laws govern the universe? Of course not; how could they, the universe primordial to any law? — tim wood
Would you characterize the world model described above as "Materialism", or "Physicalism", or merely "Atheism"? No information, no patterns, no interrelationships, just atoms whirling in the void? The missing element is Meaning, which is significant only to evolved creatures capable of knowing, and knowing that they know, hence possessing a Self Concept, and the concept of Other Minds.My view is that the world knows nothing of information, knows nothing of anything. It exists as the stuff in it that constitutes it. These things interact in certain ways and not in others. And thus the world goes from this moment to the next. No information, no patterns, just immediate continuous evolution. — tim wood
Another term for that "cottage industry" you mentioned is Philosophy. And yes, Philosophers & Scientists do indeed "define information in peculiar ways". One of those ways is to create imaginary "models" of reality, that are not in themselves real, but ideal*3. Another term for a mental model of reality is Theory. Do you know the real world directly, or only by means of models & theories (a la Kant)?*4a whole cottage industry arises that replies to the world and insists that it must work on models we create, on the basis of information, even to the extent of saying that the world itself just is information!
And the only way that makes any sense is by defining "information" in very peculiar ways, such that "information" and information no longer share meaning. — tim wood
To be clear, the "immaterial power" I was referring to is Logical Reasoning (including mathematics), which seems to have reached its pinnacle of evolution (to date) in the homo species. When we begin to allow non-human posters on this forum, I might need to be more circumspect in my language. :smile:My disagreement with philosophical Materialism is that it ignores or trivializes the immaterial power that allows homo sapiens to post on forums like this. — Gnomon
:lol: That is preposterous that an evolved species would think itself the ultimate ruler of the universe and so they make a god in their own image. — Athena
Plato & Aristotle apparently used abstract non-anthro-morphic notions of "Logos & Prime Mover" intentionally, to avoid implications of the humanoid deities of their day. Similarly, when I occasionally use the term "G*D" when referring to an unknown & unknowable creative/causal power behind the Big Bang, I often use un-gendered pronouns, such as "he/r" and "s/he". But I do so with tongue in cheek, imagining the "huh?" question mark above the head of the reader. :joke:Exactly, however, it might help if we resist using human pronouns when referring to logos or a prime mover. — Athena
If the "detail" you're looking for is empirical evidence, it's probably not forthcoming. Mathematics is a language for science, not an object to be studied under a microscope. Likewise, Energy is an intangible invisible force that is observed only in its physical effects, not as a ding an sich. Both Math & Energy are now regarded, by scientists & philosophers, as forms of Generic Information. Basically most of the referenced links in my posts are philosophical/theoretical generalizations & opinions, not empirical evidence. So, the bottom line is : do you trust these theoretical scientists to know what they are talking about?↪Gnomon
Thank you for the references. I think if you read/listen to them critically, they omit just exactly the detail needed. For example, on the assumption that information is an efficient cause, then how can that work? — tim wood
Yes. The meaning of immortality would be just the sum of meaningful experiences of the observer. Yet the perspective of infinite experiences might eventually merge into a single undifferentiated blob of memory. But, is the whole more than the sum of its parts? Wait and see. :smile:Would life as an immortal real be with less meaning? Can't we just invent it as we go in any event? — TiredThinker
Slightly off-topic : If you will think of Mathematical relationships as A> a form of Information, and B> Information as "the power to enform a mind", plus C> Energy as the power to enform matter (as in E=MC^2), then the notion of a Real universe consisting of mathematical (structural) & informational (meaningful) relationships might begin to make sense. Of course, it's a great leap from Atomism & Materialism.but I think math is the reality, — flannel jesus
I invite you to think about your own remark and the difficulties of it. What if anything can you imagine that would make math more than, other than, just descriptive and give it causal efficacy? — tim wood
JG, I'm not picking on you by posting long dissertations to your name. It's just that I'm on a roll here, expanding the topic of Quantum Entanglement is Holistic. And your math background may allow you to hold apparent paradoxes (counterintuitive results) in your mind, while keeping an open mind --- pax . For example, math has Paradoxes of infinity ; of set theory ; Probability theory : https://en.wikipedia.org/wiki/Category:Mathematical_paradoxes . But those "non-commutative" sub-sets don't invalidate the consistency of mathematics in general. Note --- I'm using that term in an unconventional way.The interplay is certainly interesting. — jgill
Yes. I think you could safely say that Mathematics is a mental philosophical language that is used by Science to describe it's sensory observations precisely. Ancient math concepts were originally devised by desert civilizations -- Egyptians & Mesopotamians -- in order to understand why the stars (gods?) formed patterns that reminded men of terrestrial things & events : Astrology. Later, Greek logicians (e.g Euclid), with cloudier skies, refined geometry to make it more abstract and less subject to variable interpretations : Astronomy."this is the idea that mathematical truths are a byproduct of our linguistic conventions". — Gnomon
The interplay is certainly interesting. — jgill
Yes. That seems to be the point that Heisenberg was making when he said " . . . . it's a question of translation : the conventional language of physics is fashioned according to the world we experience". But most of us don't directly experience the world on the subatomic level. So, it's an abstruse language for sophisticated initiates into the mysteries of the foundations of Reality. And easily misconstrued*1. The current issue (157) of Philosophy Now magazine has an article about Solving The Mystery of Mathematics. For the purposes of this article, the author -- Jared Warren -- rejects the Ideal definition of math as presented by Plato, and also the Real definition of math as "like the physics of this reality". Instead, he prefers a linguistic definition : "this is the idea that mathematical truths are a byproduct of our linguistic conventions".That's nicely done. I suppose my point is that QM is all sophisticated mathematics and equally sophisticated experimental processes. — jgill
Thanks for that quickie quantum update. I assume the article is interesting to Theoretical/Mathematical Physicists. But, can you tell me, in a few jargon-free words, what that account means -- in the real world -- to a non-mathematical layman, or to an atom-smashing CERN physicist, or to a matter-molding Chemist?Here's a quick look at ground zero in quantum studies by Mark John Fernee for Quora: — jgill
After Quantum Physics introduced Uncertainty into Science, and substituted Virtual Particles for Real Atoms, I suspect that quite a few disillusioned undergrads dropped-out of their physics programs. The most famous expression of the "switch" you noted is Feyman's "shut-up and calculate" quip*1. Since then, physics divided into large teams of experimental scientists (atom smashers) and a few individual philosophical (theoretical) scientists. But both groups are "chasing rainbows" that are more & more elusive. Also, the empiricists are typically distrustful of un-tethered Philosophical Reasoning for epistemological knowledge of Material Reality.↪Gnomon
My best friend, who passed away seven years ago, was a physics major up until the required introductory senior level course in quantum theory. He switched to mathematics and retired a fellow professor. A very bright guy - certainly smarter than me - but math made more sense at the time, easier to understand.
I think dropping a physics major at this crucial point of transition in thinking happens fairly frequently. Some become engineers, a profession using physics that moves along Newtonian lines. Well, maybe not so much electrical engineers.
It's a shame the forum doesn't have quantum physicists who might elucidate better than philosophical minded novices. But this is not a physics forum. Our best is not good enough. — jgill
I agree : picture-taking is an observation/intervention, that -- like silver & vampire -- is incompatible with mystery-shrouded superposition. And the irrational "arbitrariness" of the symbol/article juxtaposition is exactly why I started this thread. I was not trying to assert --- as some posters have assumed, and the quoted article seems to imply --- that Yin Yang is a "hard" scientific concept, instead of a "soft" philosophical conjecture.You wouldn't. By the time you can take a picture of something, the quantum superposition has already decohered.
It's good to see you've accepted the arbitrariness of the yin yang symbol in the context of this experiment. — flannel jesus
I didn't "misinterpret the paper", and I didn't "interpret the paper", because I didn't read the technical paper. I did request that others, more qualified, would interpret the significance of the symbol relative to the experiment.Do not assume that just because you managed to misinterpret the meaning of it, that it was MEANT to be misinterpreted. You said yourself that you're not qualified to interpret the paper. — flannel jesus
Thanks for that information. I asked TC where he got the information to support his assertion that the Yin Yang image was both input & output, and he did not respond. I guess I was supposed to take his word for it. But he didn't state his qualifications as an expert on the subject.You posted your opinion implying that the common Yin Yang symbol was used as input... — Gnomon
Have you looked at the original paper? (Which T Clark linked early in the thread.)
I just took a look and the caption under the only picture of the Yin-Yang symbol says:
a, Coincidence image of interference between a reference SPDC state and a state obtained by a pump beam with the shape of a Ying and Yang symbol (shown in the inset). The inset scale is the same as in the main plot. b, Reconstructed amplitude and phase structure of the image imprinted on the unknown pump. — wonderer1
I did not say that. Ignore my evidence if you want, make up your own fantasies about little fairies dancing on the taiji, but don't misrepresent what I wrote. I always thought you were a little goofy, but I didn't think you were dishonest too. — T Clark
My question was not a dichotomy. Merely an incomplete list of unknown possibilities. Maybe they are Alien beings trying to sow discord among PF posters . . . :smile:Did you interpret the symbolic image as an error of judgment, or a deliberate hoax? — Gnomon
Isn't that a false dichotomy?
Maybe a stunt to get a lot of attention to their paper? Maybe one of the researchers is into Taoism? Maybe a target that was handy and interesting enough? — wonderer1
Unfortunately, Logos and Prime Mover might be rejected by Materialists*1 as unprovable Transcendent beings or forces. For me that's not a problem, because they are merely hypothetical philosophical conjectures (thought experiments) or Axioms*2, with no need for empirical proof, only logical consistency. And, since they have no "favorite people", they provide no reason for slavish religious worship. They also have no need to "violate" natural laws, since they are essentially the LawMakers. :smile:Thank you so much! I think our discussions would be much improved the the notions of logos and prime mover. And from there, even the gods were subject to logos. — Athena
Thanks for the reference. The technical stuff is beyond me too. But the references to three different "states" provides fodder for speculation. The "unknown state" must be the entangled photons, and the "quantum state" might be the mathematical wavefunction. But the "reference state" is a mystery.Frankly, I don't know what's going on here. But at the beginning of the paper
: Here we introduce biphoton digital holography, in analogy to off-axis digital holography, where coincidence imaging of the superposition of an unknown state with a reference state is used to perform quantum state tomography.
This stuff is way beyond me. — jgill
didn't respond to my request for the source of his information/opinion about the intentional use of the YY symbol as input instead of as output of the holographic method. Will you post where & how you determined that is the case? Did you interpret the symbolic image as an error of judgment, or a deliberate hoax?The input to the experiment was the image of the yin/yang symbol — T Clark
Seems to be the case as far as I can determine. Difficult reading. — jgill
Since you are reading-into the "4mm", a prejudiced meaning which is not expressed in the image, who should be ashamed? If you can produce evidence to support your "reading", I will retract my attribution of "prejudice". :smile:Maybe, maybe not. The 4mm may be measuring the object under scrutiny, or the photographic image produced by the equipment. Some labels would help. — Gnomon
No sense going on any further. You should be ashamed of yourself. — T Clark
Yes. Materialists, for doctrinal reasons, typically lump Energy into the same ontological category as Matter. Admittedly, Energy is essential to Physics & Chemistry --- and I mean that literally. The common definition of Energy is "ability", but I think "potential" is more accurate : Energy is the potential to cause change in matter. And Potential (not-yet-actual) is by definition, immaterial and unreal --- although its effects on matter are immanent. Energy is indeed a Phenomenon, in the sense of an interpretation of sensory impressions. But the thing being interpreted is itself a Noumenon.Great question. Because that's not what the measurements indicate. Good science shows that these phenomena are part of the material world, but energetic in nature; immaterial.
What's really exciting about all of this, is that the immaterial aspects of this world are present, just waiting to be rediscovered. That is what entices me, as an individual. — Bret Bernhoft
Yes. I had imagined quantum entanglement as random noise, and the dis-entangled particle as a recognizable image. It never occurred to me that a tangle of photons would look like a Taoist symbol. :smile:Yet, this is not the point. We are talking about just a visualization. Nothing more. — Alkis Piskas
Maybe, maybe not. The 4mm may be measuring the object under scrutiny, or the photographic image produced by the equipment. Some labels would help.Here's a figure from the article from which you've clipped your yin/yang symbol. It shows the black and white input image and the colored output. Note the size, measured as 4mm, or about 1/4 inch. This does not show entangled photons, it shows the recreation of an image. — T Clark
