When I perceive a brick in front of me, I have developed beliefs about an object: the brick. This includes the belief, "there is [=exists] a brick at some approximate distance from me". If I close my eyes, I no longer perceive the brick, but my beliefs persist: I continue to belief this brick is there [=exists] at that location. Continued perception is not necessary to maintain the belief. The belief is true because it corresponds to an aspect of reality. You omit belief formation and persistence from your account. This is called object permanence: "Knowing* that objects continue to exist when they cannot be directly observed or sensed." It's a capacity we develop as infants. (See: this) Undoubtedly, you went through this stage of development, and yet you're now expressing doubt about this.when I say that an unperceived object neither exists nor does not exist, I am not saying that objects go in and out of reality. I am saying that outside all possible cognition, conception, designation, or disclosure, there is nothing of which existence or non-existence can be meaningfully asserted. You cannot truthfully say “it exists,” because existence is never encountered except in disclosure. But you also cannot say “it does not exist,” because there is no determinate object there to which the predicate “non-existent” could attach. — Wayfarer
Denying object permanence, which you learned in your first year of life, is a dramatic claim.Accordingly, existence and non-existence are not free-floating properties of a reality wholly outside cognition; they are predicates that arise only within the context of intelligibility. Outside that context, nothing positive or negative can be said at all. It's not a dramatic claim. — Wayfarer
You use "object" in 3 incompatible ways:If you take any object — this rock, that tree — and ask, “Does it exist when unperceived?” you have already brought it into cognition. To refer to it, designate it, or even imagine its absence is already to posit it as an object for thought. The very act of asking the question places the object within the space of meaning and predication. — Wayfarer
I believe the real-world object that we refer to as "the moon" exists when no one is looking at it; this is entailed by my belief in object permanance and my beliefs about this particular object. I believe real world objects have no ontological dependency on being either perceived directly, or remembered.‘Does the moon continue to exist when nobody is looking at it?’ " — Wayfarer
Punshhh
That’s not surprising because I’m in agreement with most of what physicalism says. I was narrowing down what part of existence we know. Existence as a whole and the mechanism of existence is not part of that. So to say;Nothing you've described is inconsistent with physicalism.
Is to conflate that bit which isn’t part of it with the existence we know. The bit of existence which we experience isn’t all of existence and isn’t foundational. This is self evident because we have limited capacities to experience and know things.-that mind is foundational to existence;
Yes, but I’m saying something broader than that. For example in a thought experiment I can say the Earth is a being, Gaia for Gaia the physical world might be like a thin protective layer in her skin, that she is barely aware of and her family is made up of other planets and stars. In conversation what to her is the equivalent of a word spoken in a minute might in our terms be a few million years of seismic events and most of her life is an experience of transcendent realities entirely inconceivable to us. Rather like comparing our lives to that of an individual cell in our bodies. The cell could not comprehend, or understand anything about our lives and yet we share consciousness and there is a germ of being that the cell feels, which we and Gaia also feel in some way.This is a mereological issue. Just because objects are reducible to particles doesn't imply they are not actual, functional entities in the world. By "functional", I mean that they can be analyzed in terms of their interactions with other functional entities.

The question is unwarranted (like 'Cartesian doubt'), so why it was asked is philosophically trivial. In a scientific sense, however, Einstein's question exposes the absurdity (i.e. category error) of speculatively extrapolating – as (scientistic quantum-woo) idealists/antirealists tend to do – properties from unmeasured quantum states to interacting (i.e. measured) ergo decoherent states such as "the moon" – after all, strawberries do not get their flavor from 'strawberry-flavored subatomic particles'. :smirk:‘Does the moon continue t exist when nobody is looking at it?’ Einstein asked Abraham Pais.

Agreed, but that fact does not entail that there are not determinable objects with specific determinable properties in the actual world. By "determinable", I simply mean that the mental object (along with identified properties) corresponds to something in the real world. It seems as if you deny this."determinate object with specific properties" is already a description that presupposes a framework of conceptual articulation. — Wayfarer

You made these assertions that apply to ontology:
1. Mind is foundational to the nature of existence
2. To think about the existence of a particular thing in polar terms — that it either exists or does not exist — is a simplistic view of what existence entails. In reality, the supposed ‘unperceived object’ neither exists nor does not exist. Nothing whatever can be said about it."
Both of these pertain to ontology (metaphysics). By stating them, you are expressing something you believe. Hence, they reflect metaphysical beliefs.
There is no "inherent contradiction" in the concept of a "mind independent object", but I think I understand why you say this: "object" is a concept - an invention of the mind. But this overlooks the possibility that there is a real-world referrent for the "objects"; and that there are good reasons to believe this is the case (irrespective of whether you find these to be compelling) — Relativist
But does "nature of existence" refer to the mind-independent (billions of years old) real world that you acknowledge? Whether or not your inclined to talk about it, the real world is something we can talk about, and we can talk about its "nature". That's an integral part of ontology. — Relativist
The fundamental absurdity of materialism is that it starts from the objective, and takes as the ultimate ground of explanation something objective, whether it be matter in the abstract, simply as it is thought, or after it has taken form, is empirically given—that is to say, is substance, the chemical element with its primary relations. Some such thing it takes, as existing absolutely and in itself, in order that it may evolve organic nature and finally the knowing subject from it, and explain them adequately by means of it; whereas in truth all that is objective is already determined as such in manifold ways by the knowing subject through its forms of knowing, and presupposes them; and consequently it entirely disappears if we think the subject away. Thus materialism is the attempt to explain what is immediately given us by what is given us indirectly. All that is objective, extended, active—that is to say, all that is material—is regarded by materialism as affording so solid a basis for its explanation, that a reduction of everything to this can leave nothing to be desired (especially if in ultimate analysis this reduction should resolve itself into action and reaction). But we have shown that all this is given indirectly and in the highest degree determined, and is therefore merely a relatively present object, for it has passed through the machinery and manufactory of the brain, and has thus come under the forms of space, time and causality, by means of which it is first presented to us as extended in space and ever active in time. From such an indirectly given object, materialism seeks to explain what is immediately given, the idea (in which alone the object that materialism starts with exists), and finally even the will from which all those fundamental forces, that manifest themselves, under the guidance of causes, and therefore according to law, are in truth to be explained. To the assertion that thought is a modification of matter we may always, with equal right, oppose the contrary assertion that all [pg 036]matter is merely the modification of the knowing subject, as its idea. Yet the aim and ideal of all natural science is at bottom a consistent materialism. The recognition here of the obvious impossibility of such a system establishes another truth which will appear in the course of our exposition, the truth that all science properly so called, by which I understand systematic knowledge under the guidance of the principle of sufficient reason, can never reach its final goal, nor give a complete and adequate explanation: for it is not concerned with the inmost nature of the world, it cannot get beyond the idea; indeed, it really teaches nothing more than the relation of one idea to another. — Arthur Schopenhauer, World as Will and Idea

The reason I'm not making an ontological statement, is because I've already stated 'Adopting a predominantly perspectival approach, I will concentrate less on arguments about the nature of the constituents of objective reality, and focus instead on understanding the mental processes that shape our judgment of what they comprise. ...You, however, will interpret that as an 'ontological statement' because of your prior acceptance of the reality of mind-independent objects — Wayfarer
Mind is foundational to the nature of existence
You could have justifiably said that mind provides the foundation for an understanding of existence, but as written, it was an unsupported ontological claim. — Relativist
But the concept of "object" is within minds, and therefore dependent on minds, just as each individual conceptual object (tree, dog, toilet...) is a mental construct.I'm not saying that 'objects are an invention of the mind' but that any idea of the existence of the object is already mind-dependent. What they are, outside any cognitive activity or idea about them, is obviously unknown to us. — Wayfarer
Aren't you refering to the impossibility of a perspective-less account of some named object? Refer to the bold part of my above comment.What 'an object' is, outside any recognition of it by us, is obviously not anything. Neither existent, nor non-existent.
"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

No, it's not because of my acceptance of mind-independent objects. It was because of the words you used*. Can you understand why "mind is foundational to the nature of existence" sounds like an ontological claim? This is the root of what I referred to as equivocation. You don't fully cure this with the disclaimer (i.e. the text I underlined in the above quote) because you are discussing "judgements we make about the world" - and here, you appear to be referring to the real world. Then again, maybe you're referring to "judgements we make about the mind-created world(model)". I'm sure you aren't being intentionally equivocal, but your words ARE inherently ambiguous. Own this- they're your ambiguous words! Don't blame the reader for failing to disambiguate the words as you do. Rather, you should refrain from using terms like "world" and "nature of existence" to refer to the content of minds. It's easily fixed, just as I did when revising "mind-created world" to 'mind-created world(model)" — Relativist
the adherents of correspondence sometimes insist that correspondence shall be its own test. But then the second difficulty arises. If truth does consist in correspondence, no test can be sufficient. For in order to know that experience corresponds to fact, we must be able to get at that fact, unadulterated with idea, and compare the two sides with each other. ...When we try to lay hold of it, what we find in our hands is a judgement which is obviously not itself the indubitable fact we are seeking, and which must be checked by some fact beyond it. To this process there is no end. And even if we did get at the fact directly, rather than through the veil of our ideas, that would be no less fatal to correspondence. This direct seizure of fact presumably gives us truth, but since that truth no longer consists in correspondence of idea with fact, the main theory has been abandoned. In short, if we can know fact only through the medium of our own ideas, the original forever eludes us; if we can get at the facts directly, we have knowledge whose truth is not correspondence. The theory is forced to choose between scepticism and self-contradiction. — Blanshard, Brand - The Nature of Thought,1964, v2, p268

You say I should distinguish between "judgements about the world" and "judgements about the mind-created world(model)." — Wayfarer
Of course there is, as long as one acknowledges that there IS a real-world. And notice that the term "real-world" is not ambiguous. An extreme skeptic might claim that it's inaccessible and therefore a complete mystery, because of the phenomenology/perspective-ness,, but even so - it is something we can refer to.that there is no meaningful way to refer to "the world" apart from how it shows up within some framework of intelligibility. Not because mind creates or invents the world, but because "world," "object," "tree," "exists"—all these terms only have content within a cognitive framework. — Wayfarer
You literally just referred to the "real world". Further, you acknowledged there is a mind-independent reality in your essay when you said: "there is no need for me to deny that the Universe is real independently of your mind or mine, or of any specific, individual mind."I won't adopt your terminology, because it presupposes the very thing at issue: that we can meaningfully refer to a "real world" wholly independent of cognition, and then compare our "models" to it. We cannot. Every comparison is already within cognition. — Wayfarer
This does not imply that correspondence theory should be rejected. The meaning of the word "true" is what matters. The quote merely argues that we can never directly verify the correspondence, which is irrelevant to the concept. Your observations about phenomenology could be treated as an argument against the possibility of knowledge (strict sense) of the real world- which could possibly be rational. But we need a concept of "true". There are other truth theories; correspondence is just the most widely accepted among philosophers (and for good reason).This incidentally harks back to an earlier discussion about correspondence in respect of truth.
the adherents of correspondence sometimes insist that correspondence shall be its own test. But then the second difficulty arises. If truth does consist in correspondence, no test can be sufficient.... — Wayfarer
No, I had understood that you do not believe that. My complaint is that the language you use is prima facie ambiguous in the context of discussing "the actual, real world" - which was what I was discussing.Again, you think that by saying that, I'm claiming that the world is all in the mind or the content of thought. — Wayfarer
I hadn't accused you of saying that, and I agree that perspective is a logical necessity for even entertaining propositions about the real world.

Metaphysical naturalism is a philosophical worldview that holds only natural elements, principles, and forces exist, and the supernatural does not. It is an ontological claim about the composition of reality, asserting that the universe is a unified whole that can be explained by natural laws and processes, such as those studied by science. This perspective excludes the possibility of deities, spirits, miracles, or supernatural intervention.

The epistemic foundation is subjective. But I believe that (mind-independent) objective reality exists - irrespective of whether or not any metaphysical theories are true. Like all beliefs, this belief of mine is subjective. But if the belief is true, then it is the case that objective reality exists; IOW, this would be objective fact.My claim is different: that what we call the “objective world” has an ineliminably subjective foundation—that objectivity itself is constituted through perspectival, experiential, and cognitive conditions. In that sense, the world is not “self-existent” in the way naïve realism supposes; it lacks the kind of intrinsic, framework-independent reality we ordinarily project onto it. — Wayfarer
I don't believe that objective reality is exactly as described by physics either. But I do believe that if one chooses to embrace a metaphysical theory (=ontological theory), that at minimum it must be able to account for all known facts. So in that sense, it must be consistent with physics. This consistency need not include the "ontological models" physicists discuss (including, for example, interpretations of QM).This is not a denial of realism in the sense of stable, law-governed regularity, but a rejection of the stronger metaphysical thesis that the world, as described by physics, exists exactly as it is described, wholly independent of the conditions of its intelligibility (i.e. 'metaphysical realism').
It only does this if one commits to a particular sort of interpretation of quantum mechanics. I am generally agnostic to specific interpretations, because I see no means of justifying a belief in a specific one. AFAIK, the so-called "observer dependent" interpretations have been supplanted by generalizing "observer" to include anything classical (like a measurement device) that interacts with the quantum system.modern physics—especially quantum theory—has undermined the idea of observer-free, self-standing physical reality. Hence Einstein's question!
That's not entirely correct. You are imposing your perspective of what is entailed by my claim. My belief that I am an objective existent is actually a consequence of my reasoning about reality: people, society, and the world at large and considering my role in these contexts. Regarding my relation to people: I recognized that I am similar to other people. I engage in thoughts (and have sensory sensations), and I infer that they do, as well. I also infer that the qualities that comprise my first-person-ness to me, also applies to them: I conclude that everyone is egocentric, so that my own egocentricity is not unique or special.To say of yourself “I am objectively existent” is already to adopt a third-person stance toward your own being and then retroject it into the first-person. In other words, you are importing the conditions under which others know you into the conditions under which you exist for yourself—and that distinction is precisely what the claim glosses over. — Wayfarer
So when you say that ontology can be pursued “in spite of” the phenomenological and perspectival conditions my essay focuses on, what you are really doing is presupposing precisely what philosophical ontology is meant to examine: namely, the conditi
ons under which objectivity, mind-independence, and even “being a thing” are first made intelligible to us. — Wayfarer
You're blending 2 questions:My claim is different: that what we call the “objective world” has an ineliminably subjective foundation—that objectivity itself is constituted through perspectival, experiential, and cognitive conditions.

I don't demand you describe alternative substance; rather, I've asked if you can propose an alternative metaphysical model of reality. It's fine if your answer is no, perhaps because you consider reality to be inscrutable. That seems justifiable. But just because (I assume) you can justify this doesn't imply there is no justifiable basis for another person to think that reality actually does consist of "self-subsisting things".You keep pressing me to affirm some alternative “substance” to take the place of the physical—some immaterial stuff, or “mind as substance.”...My critique targets the shared presupposition of both physicalism and substance dualism: that ultimate reality must consist of self-subsisting things. — Wayfarer

No world view can avoid an epistemological foundation, so of course I have pre-commitments: properly basic beliefs that include the innate trust that our senses deliver a functionally accurate reflection of the reality in which we live. I believe that earlier in life, you shared this innate trust, and wonder why you would abandon it. The mere possibility that we're wrong is not a rational reason to drop a belief. My suspicion is that you abandoned your innate belief because you could think of no rational basis to believe it in the first place. I'll come back to this, below.I’m not trying to be uncharitable but your responses while intelligent and well articulated show some pre-commitments that need to be made explicit. — Wayfarer

Think about Descartes famous Meditation II where he resolves to doubt the existence of the world, which could, for all he knows, be the projection of an 'evil daemon'. This was not an empty gesture. It is the kind of thoroughgoing scepticism which philosophy drives us to consider. But he found that, even though the external world might be an hallucination or a delusion, that he could not doubt that he was the subject of such delusions or hallucinations. Hence the famous 'cogito ergo sum'. — Wayfarer
I haven't asked you to prove to me it's not; I've asked you to identify a flaw in my reasoning - explain why I shouldn't maintain this belief that you once had. I took a guess at why you changed your mind: that it was because you could find no rational reason to believe it in the first place. But if we're the product of either nature, or design, in a world we must interact with to survive, then we would be likely to have a natural sense that the world we perceive is real, at least to the extent to allow successful interaction with it. The belief would not be rationally derived, but it also wasn't derived IRrationally. So I suggest that inertia wins, because the mere possibility we're wrong is not a defeater. There has to be a compelling reason to change a belief; mere possibility is not compelling.In contrast metaphysical naturalism starts at the opposite end. It starts with the assumption that the sensible world is real. Basically many of your questions amount to 'prove to me that it's not'. I don't regard that question as being philosophically informed.
Two issues:Where I'm coming from draws on all of that, but it's informed by cognitive science (hence the references to Pinter's book.) Cognitive science understands that what we take as the real objective world is generated in the brain. — Wayfarer

You have challenged, what I argue to be, an innate belief - not one developed by reasoning from prior assumptions.Not that nothing is real, that nothing matters, or anything of the kind, but again, an awareness that the way that we construe our sense of what is real is always in accordance with our prior conditioning or metaphysical commitments... — Wayfarer

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 (Martinez-Conde et al. 2008). ...
...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 (Martinez-Conde et al. 2008). The structure of the primate visual system has been mapped in detail (Kaas and Collins 2003) 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 (quick, simultaneous movement of both eyes between two or more phases of focal points in the same direction.) 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” (Chalmers 1996). ...There is a plausible functional story for the stable world illusion ...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 (Kaas and Collins 2003). 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. — Subjective Unity of Perception

Consider this: His statement does not account for WHY we believe in our own existence. He was not solving a controversy, in which people were unsure of whether or not they existed. We confidently hold the belief (implicitly) that we exist even without Descarte's identifying a rationale for this belief. A rationale, determined post hoc, does not cause belief. My position is that the cause of our basic beliefs is critical.In Descartes example, to the apodictic truth of his own existence - cogito ergo sum - which then served as the foundation-stone for his philosophy. But notice that the unassailable confidence that one has to exist, in order to even be decieved, is of a different kind or order to knowledge of external objects. — Wayfarer
You miss my point. It's not their naturalistic paradigm that matters, it's that you believe (accept as true) their results. What makes it true? Does it correspond to reality? You can't say it does. It seems to me that you can only accept it as a set of entailments of a paradigm you reject. If you reject the paradigm, you have no basis for accepting those entailments.It is true that cognitive scientists would generally assume a naturalistic outlook. But I anticipated this fact: 'It might be thought that a neuroscientific approach to the nature of the mind will be inclined towards just the kind of physicalist naturalism that this essay has set out to criticize.' — Wayfarer
You're right, but only in the strict sense of knowledge (beliefs that are true, and justified so strongly that the belief is not merely accidentally true). We could perhaps agree that the phenomenology of sensory input and the brain's creation of a world model establishes the impossibility of knowledge (in this strict sense) about the world.Concentrate on the bolded phrase: 'the world we perceive is actively constructed by the brain'. You will say, but there's a world apart from the one actively constructed by the brain.' To which the reply is: indeed there is, but you can never know what it is. — Wayfarer
Evolutionary biology, as a discipline, consists of a set of beliefs - so in that sense, it is epistemic.Crocodiles have survived unchanged for hundreds of millions of years without having to understand anything whatever. Evolutionary biology is not an epistemological model. — Wayfarer
You're referring to his "Evolutionary Argument Against Naturalism". It's described in this wikipedia article. I've read about it, debtated it, and debunked it elsewhere - on the basis that survival entails having a functionally accurate view of reality. All life depends on this. When we evolved the capacity for language, the usefulness of language entailed it's capacity to convey that same functionallyaccurate view of reality; had it not then it would have been detrimental to survival. So our ancestors accepted some statements (=believing them as true), without needing the abstract concept of truth.Plantinga, who you mention, argues on that very basis, that if beliefs are a product of evolutionary adaptation, then we have no warrant for believing them true — Wayfarer

His statement (cogito ergo sum) does not account for WHY we believe in our own existence. — Relativist

You're right, but only in the strict sense of knowledge (beliefs that are true, and justified so strongly that the belief is not merely accidentally true). We could perhaps agree that the phenomenology of sensory input and the brain's creation of a world model establishes the impossibility of knowledge (in this strict sense) about the world. — Relativist
