Truth is not subjective, although there are truths about subjective things. Objective truth: "The universe exists". — Relativist
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 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
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.
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

I don't see that as inconsistent with the fact that from the perspective of phenomenological inquiry what is fundamental for us is what we are and can be aware of. I don't agree with the kind of thinking that counts what is fundamental for us as being fundamental tout court. Such thinking is too human-centric for my taste. I view it as a conceit. — Janus
"Supposedly" a mind-independent reality?! Do you really doubt there exists a mind-independent reality? I read the following statement as indicating you agree there is a mind-independent reality: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... — Wayfarer

I know that, but I was explaining why I believe there is an external world: it is necessarily the case that our perceptions provide some access to this world that is at least functionally accurate.. So, even though your are rejecting solipsism, you seem overly skeptical that we can know something about the external world. I fully accept that our image of the world is rooted in our human perspective, but that fact doesn't imply our understanding is false or even suspect. I think it just means we need to take ourselves, and our perspective, into account when seeking objective facts about the world.I have taken pains to word the essay we're discussing in such a way as to avoid solipsism and subjectivism. — Wayfarer
Taken literally, I think this is absurd - it contradicts my view that there is an external world, that we have a functionally accurate image of it through our senses, and that this provides a foundation for learning objective facts about the world.Thus we see, on the one hand, the existence of the whole world necessarily dependent upon the first conscious being, — Schopenhaurer
Why think this is not an existential fact? Why think our inherent belief in a world external to ourselves is false or completely inscrutable?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. — Wayfarer
I completely agree with this statement, because "meaning" is a term that pertains specifically to conscious beings.the world is opened up, made meaningful, or disclosed through consciousness. — Routledge Introduction to Phenomenology, p144
Dualism could be true. We could be descended from ancestors who were directly created by a God, and it doesn't change anything: there is still an external world and our senses deliver a functionally accurate understanding of it.

It is naturalism (or physicalism) that is human-centric. Why? Because of having excluded the subject from consideration of what is real and declaring the measurable attributes of objects the sole criterion for what exists, as if that has philosophical significance, independently of any perspective whatever (something that the ‘measurement problem’ has made explicit.) — Wayfarer

Behind the Blind Spot sits the belief that physical reality has absolute primacy in human knowledge, a view that can be called scientific materialism. In philosophical terms, it combines scientific objectivism (science tells us about the real, mind-independent world) and physicalism (science tells us that physical reality is all there is). Elementary particles, moments in time, genes, the brain – all these things are assumed to be fundamentally real. By contrast, experience, awareness and consciousness are taken to be secondary. The scientific task becomes about figuring out how to reduce them to something physical, such as the behaviour of neural networks, the architecture of computational systems, or some measure of information.
This framework faces two intractable problems. The first concerns scientific objectivism. We never encounter physical reality outside of our observations of it. Elementary particles, time, genes and the brain are manifest to us only through our measurements, models and manipulations. Their presence is always based on scientific investigations, which occur only in the field of our experience.
This doesn’t mean that scientific knowledge is arbitrary, or a mere projection of our own minds. On the contrary, some models and methods of investigation work much better than others, and we can test this. But these tests never give us nature as it is in itself, outside our ways of seeing and acting on things. Experience is just as fundamental to scientific knowledge as the physical reality it reveals.
The second problem concerns physicalism. According to the most reductive version of physicalism, science tells us that everything, including life, the mind and consciousness, can be reduced to the behaviour of the smallest material constituents. You’re nothing but your neurons, and your neurons are nothing but little bits of matter. Here, life and the mind are gone, and only lifeless matter exists.
To put it bluntly, the claim that there’s nothing but physical reality is either false or empty. If ‘physical reality’ means reality as physics describes it, then the assertion that only physical phenomena exist is false. Why? Because physical science – including biology and computational neuroscience – doesn’t include an account of consciousness. This is not to say that consciousness is something unnatural or supernatural. The point is that physical science doesn’t include an account of experience; but we know that experience exists, so the claim that the only things that exist are what physical science tells us is false. On the other hand, if ‘physical reality’ means reality according to some future and complete physics, then the claim that there is nothing else but physical reality is empty, because we have no idea what such a future physics will look like, especially in relation to consciousness. — The Blind Spot

A human being is a part of the whole, called by us "Universe", a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest — a kind of optical delusion of his consciousness. The striving to free oneself from this delusion is the one issue of true religion. Not to nourish the delusion but to try to overcome it is the way to reach the attainable measure of peace of mind. — Albert Einstein, Letter of condolence sent to Robert J. Marcus on the death of a son

My issue with dualism, in the Cartesian sense, is that it tends to reify consciousness, treat it as a spiritual 'substance', which is an oxymoronic term in my view. I think some form of revised hylomorphic dualism (matter-form dualism) is quite feasble, one of the reasons I'm impressed with Feser's 'A-T' philosophy. I'm impressed by many of his arguments about the nature and primacy of reason, such as Think, McFly, Think. But he is critical of Cartesian dualism, at least as it has come down to us, and I think the 'Cartesian divide' is the source of many of the intellectual ailments of modernity. — Wayfarer

Why does this matter? No metaphysical account of the mind is without flaws, and none can be proven as true. A person could practice psychology without a metaphysical account of the mind. On the other hand, neurology depends mostly on the physical - but often relating it to the "magic" of behavior (both physical and mental). But even here, a metaphysical account doesn't contribute to the practice of the discipline.To put it bluntly, the claim that there’s nothing but physical reality is either false or empty.

For me the idea of explaining the nature of the subject in physicalist terms is simply, under a certain conception of the nature of the subject, a misunderstanding of what could be possible in attempting to combine incommensurable paradigms of thought. — Janus

Everyone knows that the earth, and a fortiori the universe, existed for a long time before there were any living beings, and therefore any perceiving subjects. But according to Kant ... that is impossible.'
Schopenhauer's defence of Kant on this score was [that] the objector has not understood to the very bottom the Kantian demonstration that time is one of the forms of our sensibility. The earth, say, as it was before there was life, is a field of empirical enquiry in which we have come to know a great deal; its reality is no more being denied than is the reality of perceived objects in the same room.
The point is, the whole of the empirical world in space and time is the creation of our understanding, which apprehends all the objects of empirical knowledge within it as being in some part of that space and at some part of that time: and this is as true of the earth before there was life as it is of the pen I am now holding a few inches in front of my face and seeing slightly out of focus as it moves across the paper.
This, incidentally, illustrates a difficulty in the way of understanding which transcendental idealism has permanently to contend with: the assumptions of 'the inborn realism which arises from the original disposition of the intellect' enter unawares into the way in which the statements of transcendental idealism are understood.
Such realistic assumptions so pervade our normal use of concepts that the claims of transcendental idealism disclose their own non-absurdity only after difficult consideration, whereas criticisms of them at first appear cogent which on examination are seen to rest on confusion. We have to raise almost impossibly deep levels of presupposition in our own thinking and imagination to the level of self-consciousness before we are able to achieve a critical awareness of all our realistic assumptions, and thus achieve an understanding of transcendental idealism which is untainted by them. — Bryan Magee, Schopenhauer's Philosophy
