No sane philosopher or scientist denies that phenomenal consciousness exists; i.e. that your phenomenal (diurnal) consciousness at this moment exists as a bone fide component of reality, in its own right. BUT , that is all that we know about it for certain. As to what its "nature" is, as to what "makes it tick", as to what the "stuff" of phenomenal (diurnal/dreaming) consciousness is ( is it a substance of some kind , for example ?), as to where it came from and how, as to why it "behaves" in the way it does in our lived phenomenal experience, as to why it is "structured"/constituted in the way that it is in lived human experience and for what purpose/s (if any ?), etc; WE HAVE ABSOLUTELY NO IDEA WHATSOEVER. What human phenomenal consciousness is, how and why, etc it comes to be , and so on, is, in short, still a complete and utter, total mystery.
What is mysterious is the ontological consciousness-matter relationship, but the subjective, phenomenological nature or essence of consciousness is not a mystery, since we all know it and are introspectively aware of it by virtue of our direct inner acquaintance with it. However, the question is whether the phenomenological nature and structure of the field/stream of consciousness as revealed to introspection is its
real essence (in Locke's sense of the term). Reductive physicalists reject the dualistic view that there is nothing more to consciousness and its qualia than what is revealed to introspection, because they believe that its real essence is hidden from introspective access and awareness, with its real essence being purely physicochemical. They claim that our inner perception of our experiences is illusory not in the sense that there aren't really any experiences, but in the sense that we don't innerly perceive them as what they really are, viz. purely physical processes in the brain.
"Let me also be clear that in declaring matter to be a natural mystery, and mind not to be, I am not in any way retracting the 'mysterian' position with respect to consciousness. The nature of experience is not a mystery, if by that we are referring to human knowledge of what experience is (its identity, we might say). What is mysterious, according to me, is how consciousness relates to matter. Indeed, we can only appreciate this mystery if we already have a good idea of what consciousness intrinsically is: if we grasped it purely functionally, we would have no deep sense of mystery. So my view, in sum, is that matter is a mystery and the relation of matter to mind is a mystery, but mind is not itself a mystery (in the special sense intended here). Consciousness, I say, is a nonmysterious thing mysteriously related to a mystery."

[McGinn calls matter "a natural mystery", because he's arguing from the point of view of Russellian epistemological structuralism in physics.]

Yes, there are different kinds of conscious contents; and regarding the unity of the field of consciousness, there is a "holistic" interpretation—"the no-experiential-parts theory"—and an "atomistic" one—"the experiential-parts theory":
"How is unified conscious experience structured? As we mentioned in Section 2.1, two incompatible models have some currency at the moment. On the experiential parts view (EP), unified conscious experience includes simpler experiences as parts or something like parts; unified consciousness has a mereological aspect. On this view, when I have a unified experience of a pain and a noise, this unified experience includes an experience of just the pain, and an experience of just the noise. These simpler experiences are the relata of unified consciousness; they are joined as parts of the unified experience of the pain and noise together. Experiences a and b are united in a third experience, c, which is their joint occurrence. On the no experiential parts (NEP) account, the conscious mental act through which diverse contents are presented does not have other conscious states, experiences, as parts. On the first view, when I have unified consciousness of experiencing, I am conscious of many experiences. On the second view, I am conscious of just one experience."

The Unity of Consciousness (SEP)
"It could be argued that our basic concept of consciousness is not the notion of a simple phenomenal state—what it is like to such-and-such at a time. Rather, our basic notion of consciousness is that of a total phenomenal state: what it is like to be a subject at a time. This yields a holistic rather than an atomistic view of consciousness. On this approach, we do not start with basic atomic states of consciousness, and somehow glue them together into complex states. Rather, we start with a basic total state of consciousness, and then differentiate it into simpler states, and ultimately into atomic states."
(Tim Bayne and David J. Chalmers:
What is the Unity of Consciousness?)
"Here it is useful to contrast atomistic theories of consciousness with holistic theories of consciousness. Current theories tend to take an atomistic or ‘building block’ (Searle 2000) approach to consciousness. Rather than account for the subject’s entire phenomenal field at once, they account for only particular conscious states—a pain, a visual experience, a conscious thought—on a case-by-case basis. Atomistic accounts of consciousness posit one mechanism responsible for making mental states conscious and another for making them co-conscious."

Philosophers of mind like Chalmers, the Churchlands, Smart, the dual-aspect theorists, etc; are all equally deluded. These people have wasted/are wasting untold years of their professional careers on what is a fool's errand; they will NEVER solve the "hard problem"; but they just don't get it; they are all suckers for punishment and will not be told, that human phenomenal consciousness is clearly (IMO and that of many others far more intelligent and learned than myself), something that human beings experience of a higher, transcendent (supermundane/supernatural) order, one that wholly eclipses our feeble human reason. Chalmers alone, for instance, has published a huge corpus of literature in philosophy of mind describing his assiduous efforts to try and solve the "hard problem", and guess how much progress he has made over the past 20 years ? I'll tell you; it's a big fat ZERO - NOTHING. He has not even scratched the surface of the problem.
Yes, he has. (This is not to say that his naturalistic dualism offers the best ontological solution.)
I don't see any good reasons to be as pessimistic as you are. As I already said several times, the neuroscience of consciousness is still in its infancy, and the currently available neuroimaging technology is still much too representationally coarse-grained to reveal all the relevant structural and functional details on the molecular level. You mustn't forget that the human brain (with its ~90 billion neurons) is the most complex and complicated physical system in the known universe. So I don't expect neuroscientists to be able to solve the hard problem and to close the explanatory gap within a few decades. Of course, there is no guarantee that they will ever succeed in doing so, but on the other hand there is no justification for the assertion that the hard problem is scientifically unsolvable in principle and that the explanatory gap is scientifically unclosable in principle.
Consciousness doesn't belong to "a higher, transcendent (supermundane/supernatural) order." It is a mundane, natural/physical phenomenon. To be conscious is to have a conscious life, with consciousness being a child of natural biological evolution. It's a natural state of living organisms or their brains. We don't know (yet)
how the electrochemical processes in (central) nervous systems realize conscious states, but there is little doubt
that they do (in a perfectly natural way which is perfectly consistent with the laws of physics.)
"I think at this point the most sane and sober conclusion is that we simply do not know enough to see how experience emerges from the non-experiential, if it does. Admitting ignorance is unsatisfying and perhaps professionally embarrassing for philosophers, but there are times when it is folly or hubris to do more. Let us mention some sobering facts. We have been investigating the human nervous system seriously for a mere one hundred and fifty years or so. The human brain is the most complex object in the known universe and, professional pride of some neuroscientists notwithstanding, we have probably only begun to scratch the surface of what there is to know. I see no reason why a decisive breakthrough is likely to be round the corner in five or ten or fifty years. Perhaps it will be several hundred years before we have even a fair grasp of the detailed facts about how the brain works. Perhaps we will never know because its scale and complexity will defeat our collective intellectual capacity. Perhaps it will require us to come up with concepts of an audacity that rivals that of quantum theory or a complexity which requires us to rely on computers to do almost all of the work before we can adequately capture the facts. In these circumstances, it would I think be presumptuous to suppose that because we are currently unable to see how the emergence might work, that there can be no natural emergence. The emergence of consciousness is arguably the most untransparent transition in the history of the universe: it is uniquely difficult, so to suppose we can from our present state of rather doleful ignorance pronounce the natural emergence of conscious experience from the non-experiential as conclusively impossible is in its own way as presumptuous as those who think we'll have the answer in the next five years."

Since Newton's era it has baffled Einstein, Niels Bohr, Heisenberg, Plank, Hawking and every other brilliant scientist ( and philosopher) to date who has pondered the riddle. A fact which tends ,IMO, to support the thesis that human consciousness is something men and women experience of a higher , transcendent order which we are utterly unable to comprehend.
We human apes might be too stupid to solve the hard problem/to close the explanatory gap, but we don't know if we are before we've arrived at the historical end of science. But science is an open-ended work in progress, and nobody can predict its future successes or failures.
We are all baffled by the riddle of consciousness, but it's a natural/physical mystery. There's nothing supernatural/hyperphysical or "magical" about it. It's made by Nature, not by God! It fully belongs to the immanent order of MEST (the matter-energy-spacetime world). As Donald Williams puts it, "ideas and experience are made of the same space-time stuff as the rest of physical nature."
Dachshund wrote: ↑May 26th, 2018, 2:29 amTo continue; getting back to my example of the "yellow dream bird"...if it is an accepted fact (and, as I say, it is) that dream consciousness EXISTS as a real entity in its own right, that is, that it exists as a bone fide objective component of reality (which almost every scientist and philosopher of minds agrees it does), then the components of the dream you are having of the yellow bird flying across the park are also (logically) real, such as the yellow bird itself, as distinct from the background of the sky and parkland it is flying through . I suppose you could say that with regard to this dream bird, I am a "qualia realist"; I am arguing that the phenomenal bright yellow shades that exist within the changing shapes/sizes of the of the outline of the flying dream bird do genuinely exist as actual "objective" components of reality.
To put it another way, lets say that this bright yellow bird is is made of "dream stuff", OK? Now, whatever this "dream stuff" happens to be ( and we have absolutely no idea whatsoever if it is some kind of substance, for ex, or sometime else altogether) , at least one thing is clear, and this is that it that the " dream stuff" of which the yellow bird is constituted is most certainly and assuredly not IDENTICIAL ( strictly speaking, a la a materialist Identity Theorist like Jack Smart) to some particular region of living neural tissue in your sleeping brain and the firing neurons, etc; it contains. For a start, brain tissue appears - to the naked eye - to look like dull-coloured reddish, purplish/greyish goop; it is not bright yellow nor feathery nor does it have any other bird-like attributes at all;( nor do any such features come to light under the microscope).
First of all, I'm a qualia realist too, a realist about subjective, experiential "impressions" (sensations, emotions) and "ideas" (mental images). Qualia (experiential/phenomenal qualities) are real entities that are constitutive of and essential to conscious states.
Yes, dream consciousness is as real as waking consciousness, being a form of imagination (which I think is the mental simulation of sensation/sensory perception).
There is a relevant distinction between the "transcendent"
intentional object of an act or event of imagining and its "immanent"
content, which consists of mental images in subjects' minds/brains. When you dream of a yellow bird, the intentional object of this case of somniatory imagination is a yellow bird and its content is a mental image or series of mental images of a yellow bird.
Your phrase "dream bird" is ambiguous, because it either means "dreamt-of bird" or "dream-image of a bird". A dreamt-of bird can be a real bird and it can be an unreal, purely imaginary one; but in either case, there is no real or unreal bird in the dreamer's mind/brain
but only a bird-image, which is not a bird.
When you dream of a yellow bird, you imagine a bird by experiencing bird-images. As I already said, I think mental images are simulative/imaginative percepts ("quasi-percepts"), i.e. mental simulations of sense-impressions such as shaped patches of (phenomenal) color, e.g. (phenomenal) yellow.
That is, what you experience when you dream of a yellow bird are imaginative color-qualia such as a yellow-quale.
According to materialist qualia reductionism, all qualia, including all the quasi-visual ones experienced by dreamers, are complex or structural physical properties of the subject's brain. But they certainly don't mean to say that when a neuroscientist sees your brain or processes therein while you're seeing or imagining a yellow bird, it/they will look yellow to him. Of course, it won't. To say that qualia are neurological properties is not to say that there is no difference between
their being experienced or internally (introspectively) perceived/observed by the subject whose brain instantiates them and
their being externally perceived/observed by another subject.
Seeing a physical quale (in a brain) is not the same as
having and
feeling it! Externally perceiving a yellow-quale is qualitatively very unlike experiencing it, because it doesn't itself involve any yellow-qualia. A physical yellow-quale you experience wouldn't look yellow to an external observer or to yourself, if you externally observed your own brain.
The important point is that this perceptual or perspectival difference doesn't entail an ontological difference between qualia and neurological properties. According to (internalist) qualia physicalism, a yellow-quale is a (complex) physical/neurological property of a brain; but this doesn't mean that those neurological properties which are yellow-qualia (or the neurological processes including them) look yellow to external observers.
