• Is there an external material world ?
    'm still unclear on what you mean by 'inherent or intrinsic reality'.Isaac

    Doesn't physicalism/materialism say that objects possess inherent reality, that they're real irrespective of your or my observation? And isn't that assertion central to the gist of the whole debate?

    Recall that passage I quoted from Pinter:

    Common sense leads us to assume that we see in Gestalts because the world itself is constituted of whole objects and scenes, but this is incorrect. The reason events of the world appear holistic to animals is that animals perceive them in Gestalts. The atoms of a teacup do not collude together to form a teacup: The object is a teacup because it is constituted that way from a perspective outside of itself.

    Pinter, Charles. Mind and the Cosmic Order (p. 3). Springer International Publishing. Kindle Edition.

    Pinter is not saying that the object does not exist, but that it's identity qua 'cup' is imputed to it by us. He extends that argument to all of the objects we perceive. This, and many of the points being made by others here, are very similar to arguments from the Buddhist philosophical teaching of 'emptiness' (śūnyatā) which likewise says that particulars have no intrinsic existence but exist in relation to other things ('arising due to causes and conditions') and their reality is imputed by the observer. Whereas the whole thrust of materialism or physicalism and in some ways naturalism is to insist that the objective domain has an intrinsic reality which is not connected to anything we think about it. (I should note I did an MA in Buddhist Studies about 10 years ago.)

    Notice also this issue is central to interpretations of quantum physics. It is why Einstein was compelled to ask the question 'doesn't the moon continue to exist when we're not looking at it?' I'm not going to argue that it does or doesn't, but point out that Einstein was compelled to say this by what was happening in physics during the 1920's, which threw his kind of scientific realism into doubt. That was essentially the background of the Einstein-Bohr debates which occupied many later decades (see Manjit Kumar 'Quantum: Einstein, Bohr and the Great Debate about the Nature of Reality'. Within that milieu, Heisenberg functions as a kind of modern representative of Platonism.)

    I asked that way round because I'm already aware of things you think are inherently/intrinsically real (numbers, lass of logic) but I still can't see from those examples alone where you're drawing the line between real and not-real.Isaac

    This is a very tricky point, because whereas above, we're discussing something very like relativism, and also touching on Buddhist philosophical ideas, this kind of thinking is much more associated with Platonism and the broader tradition that flows from it (including Aristotelianism).

    In ancient and medieval philosophy it was assumed that there was a 'scala natura', which is that the world has an hierarchical structure, with matter at the base and the divine Intellect at the apex. So the reason that numbers and geometrical forms were 'higher' is because they were further up the scale - nearer to the source, as it were. It is of course true that this understanding was essentially abandoned in the transition from medieval to modern, in which the whole idea of there being a qualitative dimension or 'scala natura' was rejected along with Ptolmaic cosmology and Aristotelian physics.

    But in any case, what I've come to understand is why the pre-modern or classical tradition esteemed mathematical and rational truths. It was because they retained a sense of them being 'higher' or 'nearer to the source' than material objects. Notice this paragraph from the Internet Encyclopedia of Philosophy:

    In contrast to contemporary philosophers, most 17th century philosophers held that reality comes in degrees—that some things that exist are more or less real than other things that exist. At least part of what dictates a being’s reality, according to these philosophers, is the extent to which its existence is dependent on other things: the less dependent a thing is on other things for its existence, the more real it is.

    Now, I think that is a sense which overall has been lost to modern and certainly to analytical philosophy. During my studies I've been piecing that story together. I notice that there is a controversy (hardly noticed outside academia) about the status of numbers, whether and in what sense they're considered real. That's the debate over Platonism in mathematics (see SEP). But that's a subset of a much larger debate over the nature of reality - whether it can be understood in terms of objects, or relations (e.g. ontic structural realism) or numbers (e.g. Max Tegmark).

    The way I've begun to integrate these ideas is in line with a kind of analytical idealsm, in which maths and what the medievals called universals are uniform structures of reason. That is they're not material in nature, nor derived from or supervening on the physical. but they're real as the constituents of rational thought. It is not quite the same as conceptualism, which holds that all such things are in individual minds, because I believe that they are the properties of any and all minds.

  • Is there an external material world ?
    I've only read that Quanta interview I mentioned but it makes a lot of sense - knowledge of physics notwithstanding.

    If one wants to argue (as some do) that there's no external world,Isaac

    It's not so much that there's no external world, but that the perception of what is external is itself a neural activity. That book I keep mentioning, Mind and the Natural Order, shows how we see everything in terms of a neurally-generated matrix of gestalts - meaningful wholes.

    I don't know if 'idealism' is the right term for it. It might be closer to 'critical realism' because it doesn't question the existence of an external world, but says that how it occurs or appears to us, is a product of the brain - so in that sense internal to thought.

    //ps// no, it's not 'critical realism'. My view is close to idealism but I don't understand that to mean that objects don't exist, but that they are lacking inherent or intrinsic reality.//
  • Is there an external material world ?
    1) a Bayesian predictive modelling stage where the cause is inferred based on prior expectations (and, importantly) data is filtered according to those prior expectation as means of noise-reduction)Isaac

    Are you familiar with quantum bayesianism?

    Along with the researchers Carlton Caves and Rüdiger Schack, he interpreted the wave function’s probabilities as Bayesian probabilities — that is, as subjective degrees of belief about the system. Bayesian probabilities could be thought of as gambling attitudes for placing bets on measurement outcomes, attitudes that are updated as new data come to light. In other words, Fuchs argued, the wave function does not describe the world — it describes the observer. “Quantum mechanics,” he says, “is a law of thought.”

    Quantum Bayesianism, or QBism as Fuchs now calls it, solves many of quantum theory’s deepest mysteries. Take, for instance, the infamous “collapse of the wave function,” wherein the quantum system inexplicably transitions from multiple simultaneous states to a single actuality. According to QBism, the wave function’s “collapse” is simply the observer updating his or her beliefs after making a measurement. Spooky action at a distance, wherein one observer’s measurement of a particle right here collapses the wave function of a particle way over there, turns out not to be so spooky — the measurement here simply provides information that the observer can use to bet on the state of the distant particle, should she come into contact with it. But how, we might ask, does her measurement here affect the outcome of a measurement a second observer will make over there? In fact, it doesn’t. Since the wavefunction doesn’t belong to the system itself, each observer has her own. My wavefunction doesn’t have to align with yours.

    It aligns near enough to all practical purposes, but they're still subjective, to some degree.

    The concept of existence is a concept. It does not follow that existence is a concept.Cuthbert

    I think it is. Anything that we deem to exist, does so by virtue of its identity - it is something (or some being) which 'stands apart' - which is what 'exist' means. This doesn't mean that absent the observer, the universe is non-existent, as non-existence is also a concept. You can imagine a universe devoid of observers, but even there the imagination provides a framework. You can't imagine a universe from no perspective.

    @Darkneos did mention somewhere that this is 're-hashed Buddhist philosophy'. Whilst that is rather a condescending expression, there is some truth in it. Buddhist Madhyamaka philosophy says that nothing possesses 'own-being' (svabhava) or intrinsic existence (reference.) This is the well-known 'doctrine of śūnyatā ('emptiness') associated with Mahāyāna Buddhism.

    In a world stripped of concepts, there is no existence as existence is itself a concept. Therefore, a fundamental prerequisite for existence is the existence of concepts. Concepts however cannot exist without a conceiving entity. Therefore, existence requires consciousness.

  • A universe without anything conscious or aware
    The natural conclusion is that either universes cannot exist in any other way but one that leads to an observer, or the observer has always been there (enter theology and/or panpsychism), and that life is simply the most physical and particulate (individual) state to date through which said observer or observers exist.Benj96

    I've been reading a very interesting book, Mind and the Cosmic Order, Charles Pinter, who's a maths emeritus. The very first paragraph says this:

    Let’s begin with a thought-experiment: Imagine that all life has vanished from the universe, but everything else is undisturbed. Matter is scattered about in space in the same way as it is now, there is sunlight, there are stars, planets and galaxies—but all of it is unseen. There is no human or animal eye to cast a glance at objects, hence nothing is discerned, recognized or even noticed. Objects in the unobserved universe have no shape, color or individual appearance, because shape and appearance are created by minds. Nor do they have features, because features correspond to categories of animal sensation. This is the way the early universe was before the emergence of life—and the way the present universe is outside the view of any observer.

    Pinter, Charles. Mind and the Cosmic Order (p. 1). Springer International Publishing. Kindle Edition.

    He goes on to develop his argument, based on neuroscience, evolutionary and cognitive science, that we (and other animals) see gestalts, meaningful wholes, as a matter of adaptive necessity. But the crucial point is that there are no such meaningful wholes in the absence of an observer.

    Common sense leads us to assume that we see in Gestalts because the world itself is constituted of whole objects and scenes, but this is incorrect. The reason events of the world appear holistic to animals is that animals perceive them in Gestalts. The atoms of a teacup do not collude together to form a teacup: The object is a teacup because it is constituted that way from a perspective outside of itself.

    Pinter, Charles. Mind and the Cosmic Order (p. 3). Springer International Publishing. Kindle Edition.

    This book has made a lot of things I've been mulling over clear to me. In relation to your OP, what I'd say is that nothing exists outside a perspective or point-of-view. That doesn't mean that, sans an observer, everything vanishes, but that any conception of what exists always contains an implicit point-of-view or perspective. Imagining the early universe prior to h. sapiens having evolved is a valid thought-experiment, but again the observing mind provides the framework within which the concept is meaningful. You can't get outside or escape from that, although we imagine we can.

  • Welcome Robot Overlords
    There's an excellent essay on The New Atlantis, by Steve Talbott, a favourite author of mine, which starts with some reflections on so-called AI. It says that in the 1970's, researchers were very confident that a truly 'thinking machine' would be feasible 'within the visible future'. But:

    The story is well-told by now how the cocksure dreams of AI researchers crashed during the subsequent years — crashed above all against the solid rock of common sense. Computers could outstrip any philosopher or mathematician in marching mechanically through a programmed set of logical maneuvers, but this was only because philosophers and mathematicians — and the smallest child — were too smart for their intelligence to be invested in such maneuvers. The same goes for a dog. “It is much easier,” observed AI pioneer Terry Winograd, “to write a program to carry out abstruse formal operations than to capture the common sense of a dog.”

    A dog knows, through its own sort of common sense, that it cannot leap over a house in order to reach its master. It presumably knows this as the directly given meaning of houses and leaps — a meaning it experiences all the way down into its muscles and bones. As for you and me, we know, perhaps without ever having thought about it, that a person cannot be in two places at once. We know (to extract a few examples from the literature of cognitive science) that there is no football stadium on the train to Seattle, that giraffes do not wear hats and underwear, and that a book can aid us in propping up a slide projector but a sirloin steak probably isn’t appropriate.

    We could, of course, record any of these facts in a computer. The impossibility arises when we consider how to record and make accessible the entire, unsurveyable, and ill-defined body of common sense. We know all these things, not because our “random access memory” contains separate, atomic propositions bearing witness to every commonsensical fact (their number would be infinite), and not because we have ever stopped to deduce the truth from a few more general propositions (an adequate collection of such propositions isn’t possible even in principle). Our knowledge does not present itself in discrete, logically well-behaved chunks, nor is it contained within a neat deductive system.

    It is no surprise, then, that the contextual coherence of things — how things hold together in fluid, immediately accessible, interpenetrating patterns of significance rather than in precisely framed logical relationships — remains to this day the defining problem for AI. It is the problem of meaning.

  • Understanding the Law of Identity
    What can be its significance?Art48

    The 'law of identity' is the most truthful, possibly the only completely truthful, instance of 'is' or 'equals'. If you trace the western philosophical tradition back to Parmenides, as that quote you mention suggests, the idea is that only 'what is' truly is, and cannot be otherwise. The reason this perplexed that ancients, is that all of the objects of perception - the denizens of the empirical domain - constantly change, decay and turn into something else - so what are they really? Is there anything about them which is real or are they merely illusory?

    Those kinds of questions are a long way removed from the attitude of modernity. I'm no expert in any of it, but am trying to re-trace the steps, so to speak, to understand the issues. It should be said that Parmenides and his contemporaries are representative of what is called the 'axial age' philosophies, which also include the Buddha and Lao Tzu. 'The term 'Axial Age,' coined by German philosopher Karl Jaspers (1883-1969), refers to the period between 900 and 300 BCE, when the intellectual, philosophical, and religious systems that came to shape subsequent human society and culture emerged.'

    There's an interesting and little-known philosopher with the unusual name of Afrikan Spir, a German-speaking Russian (actually Ukrainian) neo-kantian. I notice the Wikipedia entry on him summarised his ontology thus:

    For Spir the principle of identity is not only the fundamental law of knowledge, it is also an ontological principle, expression of the unconditioned essence of reality (Realität=Identität mit sich), which is opposed to the empirical reality (Wirklichkeit), which in turn is evolution (Geschehen).[26] The principle of identity displays the essence of reality: only that which is identical to itself is real, the empirical world is ever-changing, therefore it is not real. Thus the empirical world has an illusory character, because phenomena are ever-changing, and empirical reality is unknowable.

    I've actually found a very good PDF of Afrikan Spir's book wherein this is developed, although I haven't tackled it yet.

    That's what Yockey says is undecideable. (Hubert Yockey wrote a landmark text called Information Theory, Evolution and the Origin of Life.)

    It seems to me a problem very specific to post-Enlightenment culture, in some ways, because of the way that science has ostensibly replaced religion. There's a tendency to try and identify an origin which is commensurable with the idea of a creating God, but which can be understood naturalistically. I'm sceptical about that, but I'm not advocating for any form of intelligent design, either. But I do think that as a matter of definition it is something outside the domain of natural science.
  • The Interaction problem for Dualism
    At some point, there was a spark that produced an "inside" and an "outside", a perception that perceived a subject and a verb. It's hard to think about this, but what do you think could have been that first primordial and irreducible unit of consciousness?Watchmaker

    Subjective and objective things.Count Timothy von Icarus

    Consider that in the very simplest life-forms, characteristics emerge which are not discernable in any inorganic process. In all life-forms, there is the ability to seek homeostasis, to maintain a state of equilibrium whilst exchanging both nutrients and information with the environment, and to heal, grow, reproduce and evolve. Living things, as I've learned from Apokrisis, embody a semiotic dimension at the most fundamental level - which is what differentiates them from anything in the inorganic domain (including crystals or other repeating inorganic structures; see this reference, which suggest, among other things, that the origin or source of whatever this is, is formally unknowable in the same sense that there are propositions of logic that are undecideable.)

    So, isn't it feasible to consider that the 'interaction problem' manifests in at least a rudimentary form right at the origin of life itself? And further, that this is another aspect of the problem of comprehending the nature of subjective experience from an external perspective (referred to as 'the hard problem of consciousness'?)

    I maintain the problem of understanding the nature of mind is that we're never outside of it - it's never something that appears to us as an object, whereas that is precisely what all of the objects of the natural sciences do. To bring something within the domain of natural science is to objectify it. The problem with Descartes' model of res cogitans is that it lead to the conception of the mind as a potential object of analysis, as some existent thing (after all, 'res' means 'thing'). But no such 'thing' can ever be demonstrated to objectively exist - hence the ridicule heaped on dualism and the 'interaction problem', derided as the ghost in the machine by analytical philosophy, all of which grows out of a grotesquely mistaken caricature of the nature of life and mind in the first place.

    To understand this approach requires a different perspective - not a different conceptual framework but a different stance or attitude towards it, which we see emerging in enactivism and 'embodied cognition'.
  • A Newbie Questions about Wittgenstein’s Tractatus Logico-Philosophicus
    Such things are not to be said, but shown.Banno

    It kind of torpedoes the whole idea of philosophy as dialectic, doesn't it?

    There are sometimes comparisons made between Wittgenstein and Zen Buddhism, particularly Wittgenstein's metaphor of his work as a ladder which is discarded when it's served its purpose. But where the two differ is that Zen Buddhism is grounded in a spiritual and philosophical tradition, whereas Wittgenstein was situated in the halls of academia, where there was no similar milieu.

    The net result is that, whilst it's all well and good to gesture towards 'action not words', Wittgenstein often becomes a wet blanket to throw over the suggestion of anything whatever that is profound in philosophy.

    Maybe that's why some of his immediate successors converted to Roman Catholicism.

    The fact-value distinction creates an apparently insuperable obstacle for philosophers, but not for ordinary people.Srap Tasmaner

    Of note is the fact that it was first articulated by David Hume, the godfather of positivism and one of the leading lights of the Scottish enlightenment. So I would respond by situating the issue in the context of the history of ideas.

    One of the many authors I've discovered only recently, but who might be well-known to others here, is Alexander Koyré, philosopher and historian of ideas, and an influence on later philosophers of science including Thomas Kuhn.

    One of his books was adapted from a lecture series, and was a study of the momentous changes in worldview that characterised the scientific revolution and the advent of modernity. He says:

    This scientific and philosophical revolution - it is indeed impossible to separate the philosophical from the purely scientific aspects of this process: they are interdependent and closely linked together - can be described roughly as bringing forth the destruction of the Cosmos, that is, the dissappearance from philosophically and scientifically valid concepts, the conception of the world as a finite, closed and hierarchically ordered whole (a whole in which the hierarchy of value determined the hierarchy and structure of being, rising from the dark, heavy and imperfect earth to the higher and higher perfection of the stars and heavenly spheres), and its replacement by an indefinite and even infinite universe which is bound toether by the identity of its fundamental components and laws, and in which all those components are placed on the same level of being. This, in turn, implies the discarding by scientific thought of all considerations based upon value-concepts, such as perfection, harmony, meaning and aim, and finally the utter devalorisation of being, the divorce of the world of value from the world of facts. — Alexander Koyré, From the Closed World to the Infinite Universe

    In effect, what occured was the abandonment of any idea of there being Capital T Truth, which is, of course, too contaminated by association with religious ideas to withstand the acid of Enlightenment materialism. What was lost, in fact, was the sense of there being a scale of values, the idea that there could be anything better or worse outside individual opinion or social consensus. The reason that is an insuperable obstacle is because to challenge the consensus view that the Universe is, in fact, devoid of intrinsic meaning, is to be stereotyped as religious, which more or less disqualifies one from participation in secular culture.

  • Speculations in Idealism
    Another problem of considerable interest to me is the fact that animal vision is invariably in the form of comprehensive, integrated perceptual groups or scenes — never of isolated single objects. In fact, when vision of extended displays fails, this is a token of severe pathology. This aspect of animal vision — the fact that multiple objects are perceived simultaneously — is profoundly mysterious, and has been almost entirely neglected in current research. — Charles Pinter (personal website)


    There are intractable problems in all branches of science; for Neuroscience a major one is the mystery of subjective personal experience. This is one instance of the famous mind–body problem (Chalmers 1996) concerning the relation of our subjective experience (aka qualia) to neural function. Different visual features (color, size, shape, motion, etc.) are computed by largely distinct neural circuits, but we experience an integrated whole. This is closely related to the problem known as the illusion of a stable visual world.

    We normally make about three saccades per second and detailed vision is possible only for about 1 degree at the fovea. ...There is now overwhelming biological and behavioral evidence that the brain contains no stable, high-resolution, full field representation of a visual scene, even though that is what we subjectively experience. The structure of the primate visual system has been mapped in detail and there is no area that could encode this detailed information. The subjective experience is thus inconsistent with the neural circuitry. Traditionally, the neural binding problem concerns instantaneous perception and does not consider integration over saccades. But in both cases the hard problem is explaining why we experience the world the way we do. As is well known, current science has nothing to say about subjective (phenomenal) experience and this discrepancy between science and experience is also called the “explanatory gap” and “the hard problem”. There is continuing effort to elucidate the neural correlates of conscious experience; these often invoke some version of temporal synchrony as discussed above.

    There is a plausible functional story for the stable world illusion. First of all, we do have a (top-down) sense of the space around us that we cannot currently see, based on memory and other sense data—primarily hearing, touch, and smell. Also, since we are heavily visual, it is adaptive to use vision as broadly as possible. Our illusion of a full field, high resolution image depends on peripheral vision—to see this, just block part of your peripheral field with one hand. Immediately, you lose the illusion that you are seeing the blocked sector. When we also consider change blindness, a simple and plausible story emerges. Our visual system (somehow) relies on the fact that the periphery is very sensitive to change. As long as no change is detected it is safe to assume that nothing is significantly altered in the parts of the visual field not currently attended.

    But this functional story tells nothing about the neural mechanisms that support this magic. What we do know is that there is no place in the brain where there could be a direct neural encoding of the illusory detailed scene. That is, enough is known about the structure and function of the visual system to rule out any detailed neural representation that embodies the subjective experience. So, this version of the neural binding problem really is a scientific mystery at this time.

    Note that what is referred to above as the 'stable world illusion' is what we generally and uncritically think of as 'reality'.
  • Speculations in Idealism
    I shelled out for the Kindle edition. But as I said before, it's a very concise book, I found it very easy to read, it doesn't get bogged down in a lot of speculative analysis. I wrote to him to tell him I liked his book and got a nice reply. His site is here https://charlespinter.com/

    What art do you like?Jackson

    I am not sufficiently educated in the subject to identify any particular artist or school. As the saying goes, 'I don't know much about it but I know what I like.' I like the Impressionists. I like Marc Chagall. I don't much like abstract modernism. I like some classical works but I understand that they belong to a different historic period. As you mentioned a lot of 'pop art' is ephemeral trash. But I don't want to derail the thread.
  • Speculations in Idealism
    Is there any way at all, to reconcile the glaring contradiction in that statement?Mww

    I'll quote this passage in full to convey what Pinter is getting at:

    In the absence of features of any kind, it is impossible to describe individual objects and characterize them. What can be done instead is to compare things with one another and define them in terms of each other. For example, a straight line looks a certain way to the human eye—a way that makes us recognize it as ‘straight’—and a heavy object makes itself known to our senses by being hard to lift. But the ideal of objectivity requires that we reject these interpretations of physical phenomena, because they rest on the idiosyncrasies of sensory impressions. Instead, we must treat the objects of study in a neutral fashion, based on the way they relate to one another. For instance, we perceive a straight line as the shape of a dangling plumb line. The path of an object in free fall is also a straight line, and so is a taut string. In order to be “neutral”, you take the notion of straight line to be an undefined concept, and record the fact that taut strings, plumb lines and the paths of objects in free fall are straight lines. If you aim for objectivity, you must then go one step further: When you speak of a straight line in science, you must suppress the image of the taut string in mind. You must force yourself to forgo any mental picture of what a straight line looks like, and instead, think of it as nothing but an empty word. When you use that word, you may hold the image of the taut string in mind, but that’s for your own benefit: It may guide your intuition but should not participate in your reasoning. In order to carry out such a program, it is essential that the basic notions (distance, mass, and so on) be treated as undefined concepts related to one another by formal relations. Within the confines of scientific reasoning, these entities must have no meaning. If you yield to the temptation to imagine them in mind with a concrete meaning (for example, to imagine a line as the shape of a taut string), you must be careful not to allow the meaning to slip into your reasoning and play a role in your conclusions. For suppose you slip, and continue to identify a straight line with a taut string. Suppose furthermore that you make use of your mental image in scientific reasoning, so the validity of your conclusion rests on the intuitive image. If that were permitted, then the laws of science would depend on the meanings we attach to concepts—on the mental images we hold in mind.

    Where I see that converging with the meaning of 'noumenal' is in the definition of the term, which is 'In philosophy, a noumenon (/ˈnuːmənɒn/, UK also /ˈnaʊ-/; from Greek: νoούμενον; plural noumena) is a posited object or an event that exists independently of human sense and/or perception. ...The Greek word νοούμενoν nooúmenon (plural νοούμενα nooúmena) is the neuter middle-passive present participle of νοεῖν noeîn "to think, to mean", which in turn originates from the word νοῦς noûs, an Attic contracted form of νόος nóos[a] "perception, understanding, mind." A rough equivalent in English would be "something that is thought", or "the object of an act of thought". ' (wiki)

    In this context, noumenon means 'object of pure thought' i.e. something known directly by reason or nous, but not by way of an image or likeness - the word is derived from 'nous'. (This is actually different from how Kant uses it, but then this is something for which Kant has been criticized, by Schopenhauer, among others.)

    I do see what you're saying is a contradiction, but there's a tricky point here, which is that the noumenal 'exists independently of human sense or perception'. But that is rather different from the idea of a thing that exists independently of human sense or perception, is it not? Because, insofar as it is a sensable object, then it is (according to Pinter) a gestalt which is generated in the mind of the perceiver, not an indepently-existing object. Whereas, as Pinter is saying, the formal objects of science are defineable only in terms of undefined objects formally related (and described in quantitative terms, I would add.) As such, they are independent of sensable perception as a matter of definition, yet can be discerned by scientific analysis and measurement.
