Don't let contrarian posts deter you. He's probably been imbibing too much of his namesake beverage. Which makes everything seem pointless. :joke:Yeah, Seneca, Cicero, Aristotle - all hacks. I'm wondering why I bothered posting it. — Wayfarer
That description may be true of many people, who accept what they think they see as what is real. But to skeptical scientists and philosophers, and some poets, it does make a difference to know what is real and what is illusion. A major feature of wisdom is to know what you don't know.It strikes me that if the "real snake" (or whatever it may be) cannot be known, the mental representation snake is what is of significance to us. It doesn't matter what the "real snake" is, nor does it matter if our snake is a mental representation. — Ciceronianus the White
I haven't seen the article, but I have read the book. So, I'd say that the difference that makes a difference, between imaginary snakes and real snakes, is the practical distinction between Concrete and Abstract. Concrete things have physical properties, such as poison, that can have physical effects, such as death-by-snake-bite. But Abstract things, have their physical properties abstracted (pulled out), so what remains are ethereal meta-physical qualities (MPQ). MPQ are not inherent in snakes, but attributed by the observer. And one of the MPQ of both snakes-in-the-flesh and snakes-in-the-mind is that they can cause the real physical responses we call "fear". You may mistake a garden hose for a snake, but the fear-response will be the same. And some people have dropped dead from fear --- yet the cause was not bio-chemical toxin, but bio-mental shock.So a simple fellow like me may be inclined to ask what, if that's the case, they "really" are if they're not a snake and a train, and what the difference is between the snake and the train (or what we only "think" are the snake and the train) and what the snake and train "really" are. If there is a difference, how does that difference affect what we do with what seem to be snakes and trains? — Ciceronianus the White
I'm not sure what your point is -- other than a snarky remark -- but Potential is the difference that makes THE difference between something and nothing. It's what makes thermodynamics dynamic. It's what differentiates positive directional change from random non-directional disorder.↪Gnomon
I wonder if there can be a more compelling example of a difference which makes no difference. — Ciceronianus the White
Touche! You've made it murkily clear that, for you, there is no "substantive basis" for any ideas that don't fit into your subjective view of objectivity. Touche! :joke:↪Gnomon
Well, you've not challenged me on a substantive basis, so there's that. — 180 Proof
Yes. Hoffman is saying something much more significant and revealing than "subjective is not objective". :smile:What does he think is difference between the reality "out there" and the ideas about reality "in here"? If he says the difference is that one is "out there" and the other "in here" I'm not sure he says anything of note, so assume he says something else. — Ciceronianus the White
Quasi- and Contra- are in the eye of the beholder. maybe what you mean is contra-180proof. I would call Hoffman's analogy of concepts with computer icons to be an update of both Kant and Plato.Hoffman's quasi-Kantianism is contra-Platonic. — 180 Proof
Unfortunately, your Ideal "Realist" world would be a world without Homo Sapiens -- a world without Selves -- just TV cameras recording reality without meaning.By "anti-realist" I understand subject-dependency (i.e. conflation of ideas (maps) with facts (territory)) that is disputed by the Private Language argument and self-refuting Protagorean relativism. — 180 Proof
Is that another "truism", or merely an opinion? If your worldview is holistic, then everything that is not simplistic and reductive is more than its constituents. Sounds like we agree on something. But I'm not sure what we are disagreeing about. :wink:... ^ideas are "mental-constructs"; knowledge is more than it's constituent ideas. — 180 Proof
If the questions are misdirected, it's only because the target is fuzzy, or moving around. For example, what do you mean by "idealist (anti-realist, subjectivist) "reasoning"? That's not a rhetorical question. I offered "spiritualism" , but you are welcome to present other examples of "idealist reasoning".Too many misdirected and rhetorical questions. — 180 Proof
That's a neat black & white worldview : " Idealism versus Realism". But is your world really that simplistic, and devoid of ideas about things that could be, but are not? Are pre-suppositions idealistic while post-suppositions are realistic? Aren't hypothetical presuppositions a necessary first step toward empirically "proven" theoretical models of Reality? I doubt that you are really dead-set against human imagination, as a tool for learning. Instead, your dichotomy may be better summarized as Spiritualism versus Materialism. Where would we be now, if Einstein had never imagined himself, counter-factually, riding on a beam of light? ( (rhetorical questions) )I only denigrate idealist (anti-realist, subjectivist) "reasoning" and agree with you that philosophy and science taken together can be quite synergetic. — 180 Proof
No. I actually agree with you, that the job of science is to test & "prove" hypothetical (philosophical) conjectures & factoids, in order to turn them into reliable & settled knowledge that can be used to predict the course of Nature. Unfortunately, scientific "facts", while temporarily "adequate for some particular task", remain subject to change over time. The scientific "facts" of Newton are now referred to as "classical physics", because they have been found to be inadequate at the quantum scale of reality.↪Gnomon
Philosophy doesn't "disagree" with science (or history) over "the facts" because science (or history) provides philosophy with "the facts". You and I, however, disagree over whether or not philosophy determines "facts" – I say philosophy doesn't, and only proposes ideas about or interpretations/evalutations of facts (as well as other ideas and interpretations). Only idealists seem to conflate ideas with facts so promiscuously and then leap to the conclusion that "philosophy is a/the science". For me, a realist, philosophy is not theoretical or a science. (Witty). — 180 Proof
Yes. But, there is a wide range of those uncertain "overlaps" between "known" or "proven" facts, and "received opinions" or "heresies". The Scientific Method is a set of guidelines, intended to prevent scientists from confusing little "F" facts that are "adequate for some particular task", and capital "F" Facts that are True, now & forever, here & there. Philosophers have also devised long lists of Fallacies, to deter them from stumbling into the pitfalls of False Generalization from "known facts".↪Gnomon
Philosophers talk about (understanding) ideas and possibilities and scientists talk about (knowing) facts and probabilities, no? The latter propositions and the former suppositions, right? Yeah, in practice there are overlaps but the respective functions (i.e. epistemology & epistemes) are distinction. — 180 Proof
Yes, but the problem with any true/false dichotomy is "who says", and "whose facts". The current issue of SKEPTIC magazine has a Conspiracy Theory article entitled : "The fringe is mainstream". Professional skeptics have been struggling for almost 60 years to definitively define the Paranormal (weird, but not exactly super-natural), and to draw a line between fringe (presumably false) beliefs, and Normal/True/Mainstream worldviews.Or is it more accurate to say that some people have false beliefs. I wonder if using the word facts here blurs the issue. There have always been people who held false beliefs, assuming them to be facts. — Tom Storm
That's why most of the assertions on a philosophy forum should be taken with a grain of salt. Unlike physical scientists, philosophers -- and theoretical scientists -- are not bound by proven physical facts. Instead, they are free to suppose -- to say "what-if, given a few assumptions, X is true?" This is how Einstein discovered the physical implications of living in a relative, rather than an absolute & deterministic, world. Hence, most modern scientific "facts" are relative to a point-of-view or frame-of-reference. And they are provisional, given certain presumed preconditions.To my mind, a philosophical expression amounts to a supposition – 'Suppose X, then possibly Y' – that is, a proposal for reflective consideration (e.g. dialectics, gedankenexperiment, daily (fitness / therapeutic) praxis, etc) tested only by its comparatively rational adequacy for some reflective task, and not a proposition asserting what is or not a fact of the matter. — 180 Proof
The current issue of SKEPTIC magazine has an article debunking the modern-day belief that Giordano Bruno was a martyr to Science, as opposed to myth-based religion. In fact, his notion of many other inhabited worlds out there, was at the time, not Science but science-fiction, since he had no evidence to support that imaginative scenario. Ironically today, a primary focus of "scientific" off-world exploration is to discover tangible evidence of life on other planets, such as Mars. And the faith that life is ubiquitous & cheap, rather than rare & precious, remains an article of motivating faith in search of facts. Bruno's mistake was not in speculating that stars might be suns with solar systems of their own, but in stubbornly insisting on that 17th century fiction as a matter of faith, for which he was prepared to die.Or is it? I think the above needs to be qualified and that It is a case of the magic being in the eye of the beholders — Jacob-B

That ever sifted the best from the rest: Sapiens! — PoeticUniverse
The "belief" that Self is more important than Other seems to be inherent in how sentient beings perceive (awareness) their environment. All of our senses, including the extended sensing of Consciousness, are rooted in the brain & body of the sentient organism. And the primary purpose of sensation is to distinguish Self from Other. Once that dichotomy is established, the next determination is between Food and Self-sustenance. However, that Predator vs Prey relationship can also be reversed, as when the little fish is swallowed by a larger fish. So it's also important for survival to distinguish between Self-interest, and the interest of other Predators & Prey. Yet, it's only natural for personal interests to be most important to the self-centered Self-conscious organism.Yeah, the consequences of such believe might be very devastating; makes me wonder why such a believe would ever arise under evolutionary constraints. — Daniel
Any Self has special status in its own eyes. The fat cat purring in your lap may be thinking that you exist only to serve her own needs & purposes. Any organism capable of a self-image would presumably place its own Self at the top of the value scale. Unfortunately, we can't read the minds of all those other self-centered beings. So, we point the finger of blame at the over-weening minds that are capable of expressing their smugness in words as well as deeds.Man, it seems to me, gives itself a special status among existing things; special in the sense that Man thinks Man, somehow, is more particularly unique OR essential (OR divine) compared to other existing things. — Daniel
A pragmatic accommodation to that inherent weakness of top-down planned economies may be why China has quickly converted from a purely Socialist economy to a Mixed economy. That switch has allowed them to become an economic powerhouse. But the political ideology is still basically Marxist & Communist, which tends to minimize political independence, and to mandate Unity (collectives, communes), which minimizes Diversity, and suppresses minorities. So, they have adapted to the practical requirements of a complex economy, even as they are reluctant to follow the West into their currently chaotic social systems, pitting individual rights against collective rights, and the few rich against the many poor.History taught us that there was a fatal systemic deficiency within all Communist forms of government. Communist governments' centralized planned economies simply could not produce enough quality goods and services to meet even the basic needs of their citizens/subjects. — charles ferraro
Again, you seem to be talking nonsense : "disorder that organizes". That paradoxical notion goes right over my pointy little head. It sounds like the "emptiness of space that is full of energy" in the quote below.Just look in the mirror at the increasing disorder that's organizing you, Gnomon! From what you've written, it appears you profoundly misunderstand (or "metaphysically" deny) entropy. And btw, I'm not a "reductionist". — 180 Proof
Oh! I thought you were proposing some novel form of energy. :smile:Nope, just dark energy. Phantom energy is something on top of that, that may or may not exist. Dark energy definitely does. — Pfhorrest
I understand that you don't agree with my holistic & positive assessment of the direction of evolution. But how did you come-up with that Big Brother oxymoronic assertion? I assume you are thinking of Entropy as merely a mathematical description of the energy availability in a system. How can you equate "order" with "disorganization"? Is that how the world looks from a reductionist perspective?Instead, the universe seems to be gradually maximizing order and organization. — Gnomon
This makes no sense; in fact, it's contradictory. According to thermodynamics: order is DISorganization ... DISorder is organization. — 180 Proof
My personal cosmology is just the opposite of maximizing Entropy. Instead, the universe seems to be gradually maximizing order and organization. But, since we are currently at the You Are Here mid-point (in the graphic of my last post about the Big Rip), the amount of order right now is roughly equal to the amount of disorder.And so a universe that began as literally just an empty set, a zero, one black pixel, evolved more dimensions, larger dimensions, and more and more complex structure, because that became the best way of increasing entropy. — Pfhorrest
I just came across the term "phantom energy" which seems to be what you are talking about. If such inflationary energy actually existed, it would result in a sudden "Big Rip", which sounds more dramatic (and unpleasant) than the current projection of a "Big Sigh" during the prolonged "heat death" of the universe. This reminds me of Woody Allen's quip : "I'm not afraid of death, I just don't want to be there when it happens". :joke:So, could perhaps the second law of thermodynamics itself therefore be responsible for the creation of new energy via the expansion of space, which in turn undermines the effects of the second law on the universe as a whole? — Pfhorrest
See my reply to for an introduction to Don Hoffman's answer to your question.I just wonder what the implications are of this and:
-how much of our world view is stuff we invent ourselves
- how much control we have over our world view — John Paterson
Don Hoffman was a close associate of Francis Crick, and they worked together for years. But Hoffman was a lot younger, and began to diverge from Crick in his basic worldview. Crick was a fairly traditional reductive-materialist-classical scientist, and famously said "you are nothing but a pack of neurons". Yet, over time, Hoffman's views turned toward more holistic Eastern models of reality, in which "You" are more than your physical structure. He also was influenced by the contra-classical findings of Quantum Theory -- including the role of the observer in constructing models of reality. And I wouldn't be surprised, if Crick lived long enough to read Hoffman's latest books, that he would find his ideas "radical". Nevertheless, Hoffman remains respectful of his mentor's contributions to science.didn't know Hoffman had discussed his ideas with THE Francis Crick? I'm not surprised he was a critic.
I take it Hoffman is a lot more radical than the rather tame view that reality and our perception of it are not one and the same? — Down The Rabbit Hole
FWIW, here's my blog review of Hoffman's book, and its thesis of Model Dependent Realism.I think the most popular is Donald Hoffman's The case against reality. — Down The Rabbit Hole
It wasn't exactly a "claim", but just an observation. I don't know much about either theory. But after reading descriptions, the "principle" seemed to be more general in application than the "theorem". In any case, I concluded that the PLA would have the opposite effect from "efficiently" Increasing Entropy. Instead, it would tend to conserve available Energy, acting as a brake on the dissipating effects of energy decay -- the end result of which is the projected Heat Death of the universe.I don't see how you're getting that claim. I am both talking about the Principle of Least Action, and also talking about Noether's Theorem, but I don't see why you'd say one is a special case of the other. — Pfhorrest
Again, I'm not qualified to comment on the mathematical or physical aspects of your proposed symmetrical relationship between Space & Time, or between Free Energy & Spatial Expansion. But, I am interested in the Philosophical and Cosmological implications of the proportional relationship between Energy and Entropy.As though the conserved quantity is not just energy per se, but free energy: so as some energy becomes unfree as entropy increases, there's a commensurate creation of new free energy to keep the total free energy constant, which new energy is added everywhere equally, manifesting as an expansion of space. — Pfhorrest
Not necessarily new. I'm not a physicist, but I am interested in the symmetry between Energy & Entropy. Apparently, the universe began with all the energy it would ever have. But energy is a shape-shifter, in that it is constantly changing form, from potential to kinetic, from energy to mass, and back again. The traditional list of energy forms -- chemical, electrical, radiant, mechanical, thermal and nuclear -- may need to be updated to accommodate "Dark Energy" and "Dark Matter". But the general rule seems to be : "conserve energy, because it doesn't grow on trees". Therefore, despite speculations about "continuous creation", or "exchanging energy between mini-verses in a multiverse, our world still remains a closed system. But it's a dynamic system, and cybernetic system. So, it's a slippery bar of soap, for physicists to pin down. :smile:By our current best understanding of physics, the universe as a whole is not a closed system, because there's new energy being created everywhere all the time by the expansion of space. . . . what the corresponding symmetry to conservation of free energy would be. — Pfhorrest
:up:If you had only reason and no passion, you would be a computer. If you had only passion and no reason, you would be an animal (sorry animals, I couldn't find a better example). — TheMadFool
I tend to equate the human science of Mathematics with knowledge of the Logical structure of the universe. In mathematical analysis, we are describing certain logical relationships between things. And one result of those "equations" is a unified & holistic view of otherwise independent parts of reality. The physical parts of reality are visible and tangible. But the web of interrelationships is invisible, except to rational minds. So, Mathematics is essentially a form of Mind-reading, in the sense of Hawking's quote about knowing the mind of God.I have searched on and off for years on what philosophical movements promote, or are in agreement with, the idea that everything in our experience can be interpreted/translated as mathematics. — Paul Fishwick
OK. You have made your semantic point. But my semantic point is that "Probability" is Virtual, not Actual ; Potential, not Real ; Future, not Here & Now. :smile:Logic is empirical — RussellA
Those hypothetical dimensionless mathematical points do allow predictions that can be empirically tested. But the "objects" themselves are Theoretical, not Empirical ; Possible, not Factual. That's all I'm saying. I have no problem with hypothesis or conjecture per se. :cool:They're used to make empirical predictions. How much more factual do you want? — Kenosha Kid
Yes. Potential Energy is Virtual Energy. And unhatched eggs are virtual chickens. :joke:Potential energy is still energy. You can weigh it, for instance. — Kenosha Kid
Teleology is an inference from observation of tendencies in natural patterns. If you watch a landslide, the only "intention" (tendency) you will see is that of gravity. Which dictates that an object with no means of self-movement will be caused to move by the outside force of gravitational "attraction". In this isolated case, we don't say that gravity is an "intentional" agent, but it is a "causal" agent. However, if you add-up all the uni-directional patterns in physics, you may notice that the current state (pattern) of causal change points back to what cosmologists call a "Singularity", where the causal lines disappear into the black-hole (metaphor) of Infinity.However, I don't understand the mechanism for teleological "intention". — RussellA
I respect Koch's authority in neuroscience, but I disagree with his philosophical interpretation of the universality of Consciousness**. That's because I reserve the "C" term for the only psyche we know directly : self-consciousness. All other forms of information processing are hypothetical. Panpsychism has the "virtue" of minimizing the importance of humanity. And a bit of humility in science & philosophy is necessary to avoid over-generalizing ideas (abstractions) beyond their proper scope. On the other hand, I assume there is a hierarchy of Consciousness, with atoms at the bottom of the pyramid, and humanity at the peak -- but with more evolution to come. :cool:He is a panpsychic: "Koch has come around to the view that all forms of life — from apes, dogs and dolphins all the way down to microbes — possess a modicum of consciousness. — Pop
Exactly! According to Einstein, the potential energy of a rock (uranium for example) can be converted into actual energy by deconstructing (disintegrating) its atoms. :nerd:Mass is indeed a property of matter. But, in that stable form it is no longer the same as dynamic Energy. — Gnomon
I think the distinction you're after is potential energy, which it has by virtue of its position in spacetime, and its mechanical energy, such as momentum and spin. — Kenosha Kid
Yes. Virtual particles are theoretical objects that are used to make logical, not yet factual, predictions. Both the particles, and the prophesied future are imaginary until actualized in the real world. :smile:Or predict future empirical observations, such as the decay chains of the Higgs boson involving W bosons (which are virtual particles). — Kenosha Kid
I agree with last two assertions. But I think you are using the term "empirical" to mean "real", rather than "verifiable" or "testable". In definitions, "empirical" is usually contrasted with "theoretical" or "logical". Logic is indeed an inherent (real) aspect of Nature. But it is associated with metaphysical relationships, rather than with physical, empirically verifiable, objects. So Logic is more like a mental Theory about Reality, than a material Thing in the real world. :smile:I would argue that logic is empirical, as logic cannot exist in an empty domain.
There is no instance where a logical truth doesn't correspond with the world
]IE, ignoring coincidence as an answer, logic is empirical because logic is an intrinsic part of nature. — RussellA
Yes. Like Dark Matter, Virtual Particles are imaginary objects created from logical reasoning to explain otherwise puzzling empirical observations. And I don't doubt that they are useful constructs for the purposes of science. But I'm also aware that ancient people imagined invisible human-like agents to explain the otherwise inexplicable manifestations of invisible energy. For example, lightening reminded them of spears from heaven, so they assumed that someone was throwing them at specific targets, such as humans who offended the gods.There seem to be many measurable physical effects that seem to point to the existence of virtual particles, but "virtual particles" are not the only possible explanation of these measurable effects. — RussellA
