  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    Well this is interpretation dependentApustimelogist

    It's supported by an argument based on the double-slit experiment. That argument is that the interference exhibits the same wave-like pattern even if photons are fired one at a time. So the 'wave' is nothing like a physical wave, and it doesn't inhere in any medium so far as science can determine. (I put this to PhysicsForum, which said 'Don't be ridiculous, the particle interferes with itself' :lol: )

    This is why the nature of the wave function is contentious - its true nature is a lacuna that appears at the basis of fundamental physics. Sir Roger Penrose can't accept that due to his convictions about the way the world 'should be':

    It doesn’t make any sense, and there is a simple reason. You see, the mathematics of quantum mechanics has two parts to it. One is the evolution of a quantum system, which is described extremely precisely and accurately by the Schrödinger equation. That equation tells you this: If you know what the state of the system is now, you can calculate what it will be doing 10 minutes from now. However, there is the second part of quantum mechanics — the thing that happens when you want to make a measurement. Instead of getting a single answer, you use the equation to work out the probabilities of certain outcomes. The results don’t say, “This is what the world is doing.” Instead, they just describe the probability of its doing any one thing. The equation should describe the world in a completely deterministic way, but it doesn’t.

    Why should it? :brow:

  • The Mind-Created World
    So, irrespective of what anyone else may believe, I am justified in believing there to exist a world external to myself, which I am a part of. If this belief is true (as I am convinced), it is an objective fact, not a subjective fact that is only true for me. It is an objective fact even if everyone else holds a false belief in solipsism.Relativist

    I have taken pains to word the essay we're discussing in such a way as to avoid solipsism and subjectivism.

    I am not arguing that it (idealism) means that ‘the world is all in the mind’. It’s rather that, whatever judgements are made about the world, the mind provides the framework within which such judgements are meaningful. So though we know that prior to the evolution of life there must have been a Universe with no intelligent beings in it, or that there are empty rooms with no inhabitants, or objects unseen by any eye — the existence of all such supposedly unseen realities still relies on an implicit perspective. What their existence might be outside of any perspective is meaningless and unintelligible, as a matter of both fact and principle.Wayfarer

    To quote from Schopenhauer:

    the existence of this whole world remains ever dependent upon the first eye that opened, even if it were that of an insect. For such an eye is a necessary condition of the possibility of knowledge, and the whole world exists only in and for knowledge, and without it is not even thinkable. The world is entirely idea, and as such demands the knowing subject as the supporter of its existence. This long course of time itself, filled with innumerable changes, through which matter rose from form to form till at last the first percipient creature appeared—this whole time itself is only thinkable in the identity of a consciousness whose succession of ideas, whose form of knowing it is, and apart from which, it loses all meaning and is nothing at all.

    Thus we see, on the one hand, the existence of the whole world necessarily dependent upon the first conscious being, however undeveloped it may be; on the other hand, this conscious being just as necessarily entirely dependent upon a long chain of causes and effects which have preceded it, and in which it itself appears as a small link. These two contradictory points of view, to each of which we are led with the same necessity, we might again call an antinomy in our faculty of knowledge… The necessary contradiction which at last presents itself to us here, finds its solution in the fact that, to use Kant’s phraseology, time, space, and causality do not belong to the thing-in-itself, but only to its phenomena, of which they are the form; which in my language means this: The objective world, the world as idea, is not the only side of the world, but merely its outward side; and it has an entirely different side—the side of its inmost nature—its kernel—the thing-in-itself… But the world as idea… only appears with the opening of the first eye. Without this medium of knowledge it cannot be, and therefore it was not before it. But without that eye, that is to say, outside of knowledge, there was also no before, no time. Thus time has no beginning, but all beginning is in time.

    Where I take issue with physicalism is that it accords the objective world with an inherent or supposedly mind-independent reality, so that it would remain just so, regardless of whether any being perceives it or not. Within that framework, the mind is considered a consequent fact, a faculty which owes its existence to the vast prior period of material and biological evolution that preceeded it. But this is dependent on viewing the mind as an object among other objects, so it is a judgement that is implicitly made from a perspective outside of the mind. Which is, of course, an impossibility - the inherent contradiction of materialist theories of mind.

    For heuristic purposes, we can behave as if the external world is mind-independent and exists just it would without us. But that is a methodolical axiom, not an existential fact. The error arises from regarding the contingent facts of scientific inquiry as possessing a form of absolute veracity which they don't have. In Husserl's terms:

    In contrast to the outlook of naturalism, Husserl believed all knowledge, all science, all rationality depended on conscious acts, acts which cannot be properly understood from within the natural outlook at all. Consciousness should not be viewed naturalistically as part of the world at all, since consciousness is precisely the reason why there was a world there for us in the first place. For Husserl it is not that consciousness creates the world in any ontological sense—this would be a subjective idealism, itself a consequence of a certain naturalising tendency whereby consciousness is cause and the world its effect—but rather that the world is opened up, made meaningful, or disclosed through consciousness. The world is inconceivable apart from consciousness. Treating consciousness as part of the world, reifying consciousness, is precisely to ignore consciousness’s foundational, disclosive role. For this reason, all natural science is naive about its point of departure, for Husserl (PRS 85; Hua XXV 13). Since consciousness is presupposed in all science and knowledge, then the proper approach to the study of consciousness itself must be a transcendental one—one which, in Kantian terms, focuses on the conditions for the possibility of knowledge.... — Routledge Introduction to Phenomenology, p144
  • The Mind-Created World
    Truth is not subjective, although there are truths about subjective things. Objective truth: "The universe exists".Relativist

    Agree it's a difficult point to make. I'm saying that there is an implicit subject in every statement about what exists, including what exists in the absence of any observers. It is true that we can model the universe as if there were no observers in it on the practical or methodological level but it's not ultimately the case, because that model is mind-dependent. The universe exists for the subject - as you say, that doesn't preclude the discovery of objective facts about it, but their objectivity is not absolute or stand-alone.

    Physicalism is not a reductive theory. It is a foundational theory that purports to show that the world cannot exist without matter or the physical components.L'éléphant

    I don't think you can have your cake and eat it. Physicalism is reductionist by definition. Why? Because it methodically excludes or reduces what may be deemed anything other than the physical to the physical. Physicalism is 'the view that all phenomena, including complex processes like consciousness, emotions, and social behaviors, can be explained without residue in terms of physical components and laws—typically those of physics and chemistry—without requiring additional principles or explanations'. It is of course true that when it comes to phenomena such as gravity and the composition of massive bodies, then physicalism is a sound assumption (which is the 'methodological' aspect). But the extension of that methodology to the problems of philosophy is what is objectionable about it.

    I suggest that the interference pattern is not caused by a physical wave — because, as we shall see, no conventional physical wave can account for the actual observations.

    It's a philosophical claim in support of idealism. It is developed in more detail in The Mind-Created World OP and its linked essay.

    I see no basis to claim the evolutionary sequence was too fast or "explosive" to be due to natural processes.Relativist

    I didn't say it wasn't due to natural processes. I said it opened up horizons of being and cognitive skills that are different in kind to other species, including abstract reasoning, language, art, scientific invention, moral reflection, symbolic thought, and awareness of mortality. I would have thought this a completely unexceptionable empirical claim, although the implications may not be obvious to empiricist philosophy. I say that amounts to an ontological distinction, a different kind of being. You seem to assume that I am therefore appealing to a 'creator God' but this is something even acknowledged by existential philosophers who are not in the least theistic in orientation.

  • Donald Trump (All General Trump Conversations Here)
    It doesn’t matter if you want to call it a hate rally or a Nazi rally or an authoritarian Lollapalooza. Doesn’t matter if you want to call the speakers unhinged or ill-mannered or fascistic. I don’t care what you call the Trumpian spectacle that unfolded at Madison Square Garden last weekend.

    In this, the blessedly final week of the 2024 presidential campaign, that rally was only the latest s--t stain in a decade-long political career rooted in scapegoating and fear-mongering. After a decade of stoking fear and hatred, we have now reached Peak MAGA.

    What started in the tacky atrium of Trump Tower with a rant about Spanish-speaking immigrants ends with a lame joke by a s--tty comic about Spanish-speaking Americans, with another speaker calling Donald Trump’s political opponent “the antichrist.” We’re ten years into the Trump Era, a decade marked by racist scandal upon sex scandal upon financial scandal upon criminal scandal.

    To say that we’re numb to it all would be an understatement. Another woman came forward last week to allege sexual abuse by Trump (with a cameo by Jeffrey Epstein) this week and it barely got covered. She is the 27th woman to accuse Trump of sexual assault. Nobody cared. We expect these Trump scandals. Worse, too many Americans crave them.

    When he or his surrogates attack Puerto Ricans or Muslims or Black people or legal Haitian immigrants or people from “s--thole countries;” when Trump sits down for dinner with a Holocaust denier; when he refuses to disavow David Duke’s support or when he elevates the bats--t and antisemitic QAnon movement; when he attacks trans people; when he spends day after day spreading lie after lie, he scrapes away, layer by layer, whatever used to pass for American civility until we are left here, a raw and unnerved people looking at our fellow Americans with suspicion and fear.

    He did this.

    In 2015, Trump’s initial candidacy was dismissed as the vanity project of a reality television star. That wasn’t an incorrect assessment, but it miscalculated Americans’ appetite for inauthenticity and vulgarity. It wasn’t that Trump was a reality star whose schtick translated to real America, it’s that real America turned out to be more of a reality show than we were willing to admit. The cruelty, interpersonal conflicts, and erratic personalities that fuel our addiction to bad TV has now become central to an entire half of our electorate.

    The Madison Square Rally rally this week wasn’t an outlier, only a very special episode of The Trump Show.

    It’s been ten f---ing years of this. If, ten years ago, as Trump mulled his candidacy, somebody had sat down to write a satire of what a successful Trump campaign would look like, it would have looked very much like the coverage of the actual event. Consider the following paragraph from the actual New York Times’ coverage: “David Rem, a childhood friend of Mr. Trump, called Ms. Harris ‘the devil.’ Grant Cardone, a businessman, declared that the sitting Vice President had ‘pimp handlers.’ Sid Rosenberg denounced Hillary Clinton as a ‘sick son of a bitch’ for linking the Trump rally and a pro-Nazi event at the same arena decades ago.”

    That’s not even mentioning the fact that Hulk Hogan tried, and for a time failed, to rip off his shirt, the only Black speaker walking out to the song Dixie, and that the rally started with Tony Hinchcliffe calling Puerto Rico a floating island of garbage.

    I’m sorry, but that doesn’t read like a bad episode of Veep? (Actually, that sounds like an awesome episode of Veep but only because Veep is making fun of f---ing idiocy!)

    I don’t know how many felony convictions the collected speakers had between them, but it was a lot. Why? Because sometimes the crooks win. Sometimes, the worst among us convince the rest of us suckers and losers that we’d be better off with them running the show. When people compare Trumpism to Nazism, it isn’t because we anybody thinks Trump is “literal Hitler” as his supporters like to say.

    It’s because Trumpism displays the same hatred and buffoonery of the early Nazis with their bloviating, self-aggrandizing speeches and their cadre of big, dumb goons swinging fists in the streets. It’s because we recognize the same ugly impulses that compelled what was, at first, a minority of Germans to sacrifice their character and morality. It’s because we recognize the fear that caused good Germans to keep their mouths shut and the cold calculations that made powerful German industrialists look the other way at Nazi abuses, and which led them to ultimately collaborate.

    It’s because we know that dehumanizing language about people eventually leads to the state dehumanizing people. Can’t happen here? May I refer to you to Trump’s plan to round up millions of people from their homes and put them in detention camps? May I refer you to the fact that a recent poll found that half of all Americans, including a quarter of Democrats, support such a mass deportation? What does that look like, exactly, when the National Guard goes house-to-house in neighborhoods across the country? I’ll tell you what it looks like. It looks like Nazi Germany in the 1930’s.

    When I sat down to write this column, I thought I’d try to keep it light. But you know what? This s--t is scary. It’s scary because we’re a week away from the close of this election, but I don’t think there’s an American out there who believes that this election will end quietly.

    Drop-off ballot boxes are already exploding. Poll workers are being attacked. After one voter was told she couldn’t wear her MAGA gear into the polling station, she tore off her shirt, pushed the poll worker, and told the worker to “suck her c---.” JD Vance later tweeted about the woman, “what a patriot.”

    That’s where we are. That’s who we’ve become over the last ten years. So yeah, it doesn’t matter to me what you want to call Trump’s rally or Trump’s movement. The name doesn’t matter so much as the human rot that feeds it. For decades, we’ve been wondering how much more divisive American politics can become.

    Now we know. Hopefully next week’s election pulls us back from the brink. But what if it doesn’t? What if Trump wins? Conversely, what if he loses? What feels like the last straw often turns out to be just another straw. How many more straws before he’s broken America’s back?

  • Quantum Physics and Classical Physics — A Short Note
    *1. Heisenberg later stated that "My mind was formed by studying philosophy, Plato and that sort of thing" and that "Modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language".

    Note --- Is his "prerequisite work" good enough for you?
    Gnomon

    To me, he's the most congenial of the Copenhagen scientists, and yes, he was a lifelong Platonist (in fact, a Christian Platonist, unlike Neils Bohr, who professed no religion.) Heiseberg was philosophically both deep and adept, and I think his Physics and Philosophy is still well-regarded. Here's an excerpt from a public lecture of his delivered in the 1950's:

    ...the inherent difficulties of the materialist theory of the atom, which had become apparent even in the ancient discussions about smallest particles, have also appeared very clearly in the development of physics during the present century.

    This difficulty relates to the question whether the smallest units are ordinary physical objects, whether they exist in the same way as stones or flowers. Here, the development of quantum theory...has created a complete change in the situation. The mathematically-formulated laws of quantum theory show clearly that our ordinary intuitive concepts (such as 'it exists' - wf) cannot be unambiguously applied to the smallest particles. All the words or concepts we use to describe ordinary physical objects, such as position, velocity, color, size, and so on, become indefinite and problematic if we try to use them of elementary particles. I cannot enter here into the details of this problem, which has been discussed so frequently in recent years. But it is important to realize that, while the behavior of the smallest particles cannot be unambiguously described in ordinary language, the language of mathematics is still adequate for a clear-cut account of what is going on.

    During the coming years, the high-energy accelerators will bring to light many further interesting details about the behavior of elementary particles. But I am inclined to think that the answer just considered to the old philosophical problems will turn out to be final. If this is so, does this answer confirm the views of Democritus or Plato?

    I think that on this point modern physics has definitely decided for Plato. For the smallest units of matter are, in fact, not physical objects in the ordinary sense of the word; they are forms, structures or — in Plato's sense — Ideas, which can be unambiguously spoken of only in the language of mathematics.
    Werner Heisenberg, The Debate between Plato and Democritus

    Regardless, it is a sad but unavoidable fact that Heisenberg's association with Hitler's nuclear program has tarnished his name. I did read an OP many years ago, which I can't re-locate, to the effect that he was less than a willing participant in this effort, and may even have surreptitiously stalled the program by directing it in ways that he knew would prolong the amount of time necessary to develop it. But the fact still remains.

    It's a philosophical question that I don't trust philosophers to answer.flannel jesus

    Don't know if I agree. In our culture, since the Enlightenment, we've been told time and again that Science is the Arbiter of Truth, that scientists will provide answers that you can't find in the hazy fog of metaphysics, etc. People were willing to shout about LaPlace's Daemon from the rooftops, you'll still find many here today who believe in physical determinism. But when Heisenberg came along and basically torpedoes that idea, well, let's not venture there, you can't do the math!

    I've frequently mentioned several excellent books on meaning of modern physics (see this post.) Yes, they're difficult reads in places, and there are definitely some aspects that are beyond the skills of those without mathematical physics training. But that doesn't kick the whole debate into the long grass.

    Right! Excellent start, and thank you for the acknowledgement. My knowledge of McLuhan is second-hand although I do recognise that he was a pivotal thinker. (Another in that vein is Neil Postman, Amusing Ourselves to Death.)

    Trying to think of a few of the books that influenced my philosophical development over the years: The Tao of Physics, Fritjof Capra; Where the Wasteland Ends, Theodore Rozak; Why Us? James le Fanu; Understanding the Present, Bryan Appleyard; The Sleepwalkers, Arthur Koestler - to name a few. What they have in common is the asking of Big Questions, against a backdrop of history of ideas. Of how the Western worldview developed. I recommend a synoptic and thematic approach - following how ideas develop over history. Actually another book that comes to mind in that respect is Russell's History of Western Philosophy - despite its critics, it is very good at putting things in that historical context.

    So - please do carry on, but try and anchor your insights against sources. There is a practically endless amount of media on YouTube, plus quality publications like Aeon.co, Quantumagazine.org, Ted talks, BigThink, to mention a few.

    Here's the thing, the angst-driven "What do I focus my attention on?" precedes everything.

    If consciousness functions as a boundary administrator, formatting the picture of reality into the physical world of material objects with discrete boundaries in space and time, then there is the suggestion that at the QM scale on down to the Planck scale, an interval wherein, presumably, consciousness is not yet assembled, the state of the system is superposition. If so, then we can associate superposition with Kant's noumenal realm of things-in-themselves.ucarr

    The problem with your ideas is that they are too idiosyncratic, and that they don't reference anyone else's work in philosophy, cog sci and other fields.

Your posts often contain many sweeping statements with deep implications, but that alone doesn't guarantee quality.

  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    My contention is that our perceptions provide a reflection of objective reality, not identical to it, but we can have success at uncovering additional objective truths about reality.Relativist

    Sure, but that doesn't refute the objectivist claim that at a fundamental level, the objects of scientific analysis are 'just so', independently of any knowledge of them. They are not, in that sense, truly mind-independent. That is where quantum physics undermines the intuitive sense of the objectivity of the external world. I'm not denying that there are objective facts - that would be out-and-out relativism - but that objectivity can ever be complete. Consider the titles of three of the popular books I've read about it - Quantum: Einstein, Bohr and the Great Debate About the Nature of Reality, Manjit Kumar; Uncertainty: Einstein, Heisenberg, Bohr, and the Struggle for the Soul of Science, David Lindley; and What is Real?: The Unfinished Quest for the Meaning of Quantum Physics, Adam Becker. Notice the common thread in all these titles. It says something serious about the limitations of objective science and the conundrums that modern physics throw up. And I don't think Armstrong's style of objectivist materialism has the resources to deal with that.

    Of course there's more about reality than we truly understand at this time, and I believe it likely that there are aspects of reality that we will never understand. But just because we don't understand everything about the way the natural world works does not imply there is something unnatural at play in the world. To argue that would be an argument from ignorance.Relativist

    No, it's an argument from epistemic humility.

    It's not true that homo sapiens are the only organisms that think logically. At its core, logical reasoning entails remembering cause-effect relationships. Many animals exhibit behavior that entails multiple steps to achieve an objective. This is basic logical thinking.Relativist

    It is an established fact that the forebrain of h.sapiens evolved explosively over the period from the early australopithecus until the arrival of h.sapiens approximately 100,000 years ago. The neural capacities that this provide are exponentially more powerful than anything possessed by other animals including our simian forbears. My claim is that due to this, h.sapiens crossed an evolutionary threshhold that cannot be explained purely in terms of biological theory, as we have realised 'horizons of being' that are simply not available to other animals. These include abstract reasoning, language, art, scientific invention, moral reflection, symbolic thought, and awareness of mortality, that are all uniquely human. They indicate a qualitative leap, a difference in kind, rather than a mere quantitative increase in cognitive ability.

    (Interestingly there's a 1950's book by one of the founders of the modern neo-darwinian synthesis, Theodosius Dobzhansky, called The Biology of Ultimate Concern, one of many books that address this theme, but notable because of Dobzhansky's status in the formulation of modern evolutionary science. (It was Dobzhansky who coined the phrase 'nothing in biology makes sense except for in the light of evolution'.) This book contradicts Dawkin's type of argument that there is an irredeemable conflict between evolutionary biology and religious philosophy.)

    I say that Armstrong's type of philosophy is hanging on to the remnants of the Christian belief in divinely-ordered nature, sans God, which was replaced with the scientist.
    — Wayfarer
    It's not "hanging on" for the sake of hanging on. It wouldn't make sense to deny the existence of laws of nature just because past natural philosophers identified them as laws ordained by God.

  • The Biggest Problem for Indirect Realists
    I get what Kant was saying hundreds of years ago, but we've learned much more about the brain since then.Philosophim

    I don't think you can deflate Kant's claims so easily. Despite the 'marvellous progress of modern science' there are philosophical issues which will not yield so easily to those clever folks in their white lab coats.

    A scholar named Andrew Brook has published books and papers on the intersection of Kantian philosophy and modern cognitive science, exploring how Kant’s insights align with and contribute to contemporary understanding of the mind. Brook’s work emphasizes that Kant anticipated several concepts central to cognitive science, particularly the notion that cognition involves active processes of structuring and organizing experience rather than passively receiving sensory input. Brook sees Kant as a precursor to theories in cognitive science that propose the mind as a system that imposes order on incoming data, emphasizing the mind’s role in synthesizing raw sensory data into coherent experiences.

    For Kant, as Brook underscores, this means that the mind doesn’t simply react to raw sensory data; rather, it actively organizes and interprets it in line with certain fundamental principles that are implicit in the nature of experience itself. These principles—such as causality, unity, and temporality—are not derived from experience but are necessary for experience to have any coherent form. Brook views Kant’s insight here as crucial: it suggests that experience is structured by inherent cognitive faculties that synthesize sensations into a unified whole, making perception itself possible. This structuring role of the mind underpins cognitive processes, creating a foundation on which experience unfolds.

    That process is what is described as 'transcendental' - not in the sense of 'beyond experience' but implicit in the nature of experience. It is 'transcendental' in the sense that it refers to the conditions that are always operative within experience, shaping it from within, not transcending it in a mystical or otherworldly sense. The transcendental conditions Kant describes, which Brook highlights, operate in a way that is fundamentally invisible to direct introspection. They’re not accessible through casual reflection or even careful self-observation, because they are so ingrained in the structure of experience that we can’t “see” them directly. They function as the very backdrop against which experience is possible, like the frame of a picture that remains unseen because our attention is always focused on the content within.

    One of Brook’s focal points is Kant’s idea of the “transcendental unity of apperception,” which describes the self’s role in providing coherence to experience. Brook interprets this as a fundamental cognitive function: the capacity to unify various sensory inputs and thoughts under a consistent self-conscious perspective. He connects this to modern discussions on self-awareness, suggesting that understanding the self’s role in cognition is critical to grasping how mental states are integrated. Brook also argues that cognitive science benefits from a Kantian perspective in addressing issues like consciousness, self-reference, and the structured nature of perception, showing that Kant’s insights help bridge philosophical inquiry and empirical study, while deepening our grasp of the mind’s foundational structures.

    Kant’s influence persists in social sciences and philosophy precisely because his insights about the mind's role in shaping experience laid the groundwork for modern theories that emphasize the constructive nature of perception and knowledge. Constructivism, for instance, echoes Kant by asserting that knowledge is actively constructed, not merely passively received. Enactivism, with its focus on the dynamic interaction between organism and environment, builds on Kant’s notion that perception depends on structures and activities within the perceiver, rather than solely on external stimuli. Phenomenology also draws deeply from Kant by emphasizing the role of consciousness in constituting the meaningful world around us, exploring how subjective experience shapes our understanding of reality.

    In all these approaches, Kant’s idea that our minds contribute fundamental structures to experience remains a guiding principle. Each tradition takes up Kant’s insight in its own way, exploring how knowledge, perception, and meaning arise through active engagement with the world, rather than as direct imprints of objective reality. This ongoing influence shows that Kant’s work continues to offer essential insights into how we understand ourselves and our place in a world that we, in part, construct through our own cognitive and perceptual frameworks.

  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    My point is that the set of properties that emerge are objectively presentRelativist

    And mine was that they're not objective until they're measured. And even then, there are experiments which indicate that those measurements will vary for different observers, which again throws their objective status into question.

    See Quantum by Manjit Kumar, which is a very detailed account of the Bohr-Einstein debates. Whilst there are many arcane details, the basic point that comes through very clearly is that Einstein held to scientific realism, pretty well exactly in Armstrong's sense, while Bohr challenged that realism, saying things like 'It is wrong to think that the task of physics is to find out how Nature is. Physics concerns what we say about Nature', and 'No phenomenon is a real phenomenon until it is an observed phenomenon.' John Wheeler said of Bohr: 'The dependence of what is observed upon the choice of the experimental arrangement made Einstein unhappy. It conflicts with the view that the universe exists "out there" independent of all acts of observation. In contrast, Bohr stressed that we confront here an inescapable new feature of nature, to be welcomed because of the understanding it gives us. In struggling to make clear to Einstein the central point as he saw it, Bohr found himself forced to introduce the word "phenomenon". In today's words, Bohr's point - and the central point of quantum theory - can be put into a simple sentence: "No elementary phenomenon is a phenomenon until it is a registered (observed) phenomenon".

    there's nothing about the application of logic that is inconsistent with physical mechanismRelativist

    As we ourselves understand logic, we are able to create systems that perform logical operations. But that doesn't mean that the mechanistic analogies for organism or natural thought, such as those often entertained by materialism, provide an account of the nature of logic. Materialists never tire of telling us that the Universe is devoid of logic and that everything we see is a consequence of the undirected physical 'laws of nature'. So how an organism (if that is indeed what we are) which is purportedly a product of those same undirected forces can come to some degree of understanding the Universe is rather a mystery, isn't it? Charles Darwin himself expressed doubt - 'But then with me the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey's mind, if there are any convictions in such a mind?'

    We interact with the world to survive. Successful interaction is dependent on our pattern-recognition capacity which enables us to distinguish types of objects and activities.Relativist

    Right. And practically every other species apart from h.sapiens has survived, often for hundreds of millions of years (such as crocodiles) with no capacity for logic whatever. And trying to account for reason in terms of evolutionary theory reduces reason to an adaptation serving the purposes of survival. But if that is what it is, why do we place trust in reason?

    Empiricism in science leads to theories, established by abductive reasoning. By extension, we can abductively conclude there are laws of nature, on the basis that this best explains the success of science.Relativist

    I've pointed out a number of times that it's not clear that the 'laws of nature' are themselves physical. We never observe the laws, but only predictable outcomes which indicate that they exist. Physics can be carried out without reference to such laws, which is instrumentalism or pragmatism. Some have used abductive reasoning as evidence for a higher intelligence. So the point is, the existence of laws is not evidence for physicalism. I say that Armstrong's type of philosophy is hanging on to the remnants of the Christian belief in divinely-ordered nature, sans God, which was replaced with the scientist. There's another Armstrong, Karen, who has an excellent book, The Case for God, on the way the modern belief in natural law grew out of the faith of early modern science, but eventually gave rise to atheism.

  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    Objects are made of these particles, and each particle has a well-defined set of properties. The existence of these particles were deduced, not perceived by the faculties of our "phenomenal awareness", but over time - their existence has been confirmed through measurements in particle accelerators. So tell me in what sense is this NOT objective reality.Relativist

    The properties of particles are not defined until they are measured. That is the central philosophical problem of modern physics. The Copenhagen interpretation says it's pointless to second-guess what lies behind these measurements as it is indeterminate. The many-worlds interpretation attempts to deflate that mystery but at the cost of infinitely many proliferating universes.

    There's an anecdote, told by Werner Heisenberg, of Neils Bohr giving a lecture to the remaining Vienna Circle positivists in the 1950's (some of their principals having died or retired by then.) Bohr laid out the basics of quantum physics, in line with the 'Copenhagen' approach which he helped define. At the end of his talk, the audience applauded politely but had no questions. It was this that prompted Bohr to say 'if you're not shocked by quantum physics, then you can't have understood it!'

    It's a shame you can only see it through your pre-concieved notion of what a 'religious point of view' must be.

  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    Computers demonstrate that logic can be mechanized, so I don't understand what you see as a problem.Relativist

    Computers don’t come into existence de novo. They are artefacts built by humans according to human aims and purposes. In other words, whatever purposes they pursue are extrinsic.

    Armstrong advocates 'central state materialism' which claims that thought contents simply are brain states - a form of brain-mind identity. But brain states have physical properties (neuron firing patterns, biochemical reactions), whereas propositional content possesses semantic properties (meaning, truth-value). I don't think physicalism can explain how semantic properties emerge from, or are identical to, these physical states without appealing to, or assuming, non-physicalist explanations of meaning. As Feser says 'Brain processes, like ink marks, sound waves, the motion of water molecules, electrical current, and any other physical phenomenon you can think of, seem clearly devoid of any inherent meaning. By themselves they are simply meaningless patterns of electrochemical activity. Yet our thoughts do have inherent meaning – that’s how they are able to impart it to otherwise meaningless ink marks, sound waves, etc. In that case, though, it seems that our thoughts cannot possibly be identified with any physical processes in the brain. In short: Thoughts and the like possess inherent meaning or intentionality; brain processes, like ink marks, sound waves, and the like, are utterly devoid of any inherent meaning or intentionality; so thoughts and the like cannot possibly be identified with brain processes.' And the attempt to infer the relationship of brain states and inferential content can't proceed without relying on the very faculty that you're seeking to explain.

    What's the problem with the way Armstrong appeals to physics? (i.e. the basis for believing there exist laws of nature).Relativist

    It's this:

    When Armstrong refers to "laws of nature", he's not pointing to scientific theories and equations in textbooks. He's referring to something ontological. Physics may approximate the law, or describe it in terms meaningful to us, but those descriptions and equations are not the law. The law is the physical relations that exist between (or among) types of things (a type of thing is a universal).Relativist

    What is that 'something ontological', and how can it be described as physical, when it's not described by physics? It's a bit disingenuous to appeal to science whenever it suits your aims, but then disavow it when it doesn't.

    Besides, physics assumes the order of nature - it doesn't explain it, nor need to explain it. As A N Whitehead puts it in Science and the Modern World, science itself depends on the belief that the natural world follows a regular, coherent structure. This regularity allows science to generalize from specific observations and to formulate laws that describe the behavior of natural phenomena. But, he says, this assumption of natural order is itself a metaphysical commitment, one that exceeds the bounds of empiricism, but is essential for science to proceed. In other words, science assumes the universe is not chaotic or random but instead governed by principles that are discoverable and consistent over time*. All of which is patently obvious in Armstrong.

    This assumption is grounded in the history of Western philosophy, particularly in medieval and early modern thought, where thinkers like Aquinas and Newton envisioned a rational structure to the cosmos, often influenced by theological ideas of a divine order. Whitehead notes that even as science moved away from explicitly theological explanations, it retained this foundational belief in an orderly universe. I think Armstrong's philosophy is built on this ground - a divinely-ordained cosmos sans divine intellect.

  • “Distinctively Logical Explanations”: Can thought explain being?

    Right. But naturalism then presumes that the mind which knows it, is the product of that process it only knows metaphorically.
  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    Armstrong's physicalist metaphysics could be wrong (perhaps the mind isn't physical, or perhaps there are no actual laws of nature), but the same is true of any metaphysical system that has been, or ever will be, proposed.Relativist

    That's not an argument, but an observation. If you're an idealist, then you believe that Armstrong's physicalist theory is wrong, and will argue accordingly. I've presented many arguments against physicalism, which I hope are persuasive. (But then, people do have their predispositions.)

    I think the only thing that a physicalist framework struggles with is theory of mind.Relativist

    I think its failure on that score is beyond reasonable doubt. The crux of that issue is logic itself, reason itself. I don't see how can there be any plausible physicalist account of the nature of reason, which inheres in the relationship of ideas, 'if-then' statements.

    If physicists can't unequivocally demonstrate which interpretation is true, then certainly a philosopher isn't well-positioned to figure it out for themRelativist

    Nor can philosophers then appeal to physics in support of what they describe as 'physicalism'. And if their physicalism is not supported by physics, then why does it deserve that designation.

    I believe that there is some element of consciousness in most if not all living things. I also believe that consciousness is at the heart of reality and that all of us ultimately come from this core consciousness.Sam26

    From a philosophical perspective, it might be instructive to consider the Buddhist view of re-birth. It is often assumed that 'Buddhists believe in reincarnation', but it is not actually true. In the very earliest Buddhist texts, the Buddha firmly rejects the idea of there being a soul, self or person who migrates from one life to another. Yet at the same time, the Buddha is said to have insight into the fate of beings after death, and it is widely accepted that beings are reborn in one of the 'six realms of existence' after physical death.

    It's a hard idea to communicate in a few words, but the basic point is that beings propogate causes during this life, which will give rise to, or manifest as, living beings in future lives. Even though there isn't a kernel of unchanging personality which continues or migrates from one life to another, when a child is born, that child will manifest inherited tendencies, proclivities, inclinations, and so on, which were set in motion in previous lives, as a result of previous actions (or karma). There is a term in some Buddhist schools, 'citta-santāna', translated as 'mind-stream' which seeks to convey this idea. It is sometimes linked to a teaching associated with later (Mahāyāna) Buddhism, of the 'storehouse consciousness' (alayavijnana) which can be compared to a 'collective unconscious'. So the person is more like a process, and indeed there have been comparisons between Buddhism and Western 'process philosophy', which is customarily said to have begun with Heraclitus.

    As to whether this implies that beings 'originate from core consciousness', Buddhism doesn't generally teach in those terms, although East Asian teachings of 'Buddha Nature' might be interpreted along those lines.

  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    Thanks for taking the time! Just for clarity, I will be upfront about my attitude towards Armstrong. When I enrolled at University (decades ago now), he was the Professor of Traditional Philosophy. I never studied under him, but I was aware that his magnum opus was 'Materialist Theory of MInd'. My quest was of a somewhat spiritual nature ('spiritual' is actually not a very good description of my interests, but there are not many alternatives in the current lexicon.) In any case, I identified scientific and philosophical materialism as the opponent, a philosophy that essentially devalued and misunderstood something fundamental about human existence. I've always argued against materialist theory of mind and have devoted time to reading and debating David Chalmers, Thomas Nagel and Bernardo Kastrup, notable critics of it. So that's where I'm coming from.

    What Armstrong is doing is acknowledging a distinction between the actual laws of nature and the academic discipline of physics. Physicists endeavors to uncover laws of nature, and is likely correct in many cases, but ontology is not dependent on them getting everything exactly correct. Isaac Newton's theory of gravitation seemed to be a law of nature for quite a long time, but in fact - it had an error, one that was corrected by Einstein's theory. The law of nature didn't change, but the law of physics did change.Relativist

    But first, what we know of the 'laws of nature' is customarily understood to be the province of natural philosophy (precursor of today's science). So what 'actual laws of nature' there are, would be in science's court.

    Secondly, whether there *are* 'laws of nature' is nowadays contested. See for interest Nancy Cartwright No God, No Laws, where 'laws' can be understood as being prescriptive and determinative of what exists in nature. She argues without them being underwritten by God, then they lack the capacity to 'make things happen' (hence the title. I don't particularly want to pursue that line of argument but it has Armstrong's conception of 'law' in its sights. Nowadays it is common to encounter opinions that the concept of natural or scientific law is obsolete, although I don't agree with that, either.)

    And third, if Armstrong’s metaphysics is founded on the idea of scientific laws as real and necessary features of the world, then one would expect it to appeal to scientifically established theories. Yet by not “being bound by actual physics,” Armstrong’s conception of laws becomes somewhat abstracted from the very empirical framework that supposedly substantiates it. In a way, he’s attempting to have it both ways: appealing to the supposed authority of scientific realism to bolster his metaphysical position while remaining unanchored from science’s provisional and revisable nature (see also Hempel's Dilemma.)

    About ontology - strictly speaking, it is 'the study of the nature of being'. 'Ontology' has uses in current English, for example in information technology, where it refers to the inventory of types of system in a network. But the original meaning was the study of the nature of being (derived from the Greek verb for 'to be'). I've had many a debate here about the implications of this term, because I seek to make a distinction between the 'nature of being' and 'the analysis of what exists'*. The former is nowadays associated with phenomenology and existentialism, while the latter is firmly in the province of the natural sciences. Armstrong would of course claim that the former can be reduced to the latter, which is a foundational move of scientific materialism.

    The state of affairs of a quantum system is perfectly describable as a Schroedinger equation. In that respect, the quantum system evolves in a strictly deterministic way over time.Relativist

    You wonder why, then, Schrödinger published his notorious thought-experiment on the not-dead-or-alive cat. He sought to illustrate the fundamental indeterminacy that characterises the so-called 'fundamental particles' of physics by providing a hypothetical example of their absurd implications were they to manifest on the level of everyday experience. The fact that the equation is accurate is not at issue, as it is firmly established that the accuracy of the predictions of quantum mechanics exceeds anything previously discovered in history. It's what they say, or don't say, about the so-called fundamental constituents of reality that is the philosophical point at issue. In other words, it's the ontological implications that are at issue, not the practical effectiveness. The fact that Armstrong can blithely wave these away says something about his theories, in my view.
    ----
    *Regarding the distinction between the nature of being and the study of what exists, one of my opponents linked an apparently-classic article Charles Kahn 'The Greek Verb "To Be" and the Meaning of Being' which unfortunately for him tended to favour my side of the argument.
  • The Empty Suitcase: Physicalism vs Methodological Naturalism
    When Armstrong refers to "laws of nature", he's not pointing to scientific theories and equations in textbooks. He's referring to something ontological. Physics may approximate the law, or describe it in terms meaningful to us, but those descriptions and equations are not the law. The law is the physical relations that exist between (or among) types of things (a type of thing is a universal).

    So when I said that laws of nature are necessarily natural, if naturalism is true, I was specifically referring to laws as something ontological, not descriptive.
    Relativist

    But if they're not the laws described by physics, then in what sense are those relations physical? What about the relationship between sign and interpreter? I question that declaring everything to be physical, without any reference to physics itself, is even meaningful.

    The essential element of his ontology is that every thing that exists is a state of affairs (a particular with its attached properties and relations). Even quantum fields, or strings, fit this framework.Relativist

    But that is not true. Scientific realists, including Sir Roger Penrose and Albert Einstein, both criticize quantum physics precisely on the grounds that they provide no description of specification of what the 'state of affairs' of a quantum system is, prior to it being measured. This is why they both insist that quantum physics must be in some sense incomplete. Yet it has withstood every test that has been set for it. (I've published a Medium essay on this topic.)
