    There is no activity in the Rods and Cones when Dreaming. Eye movements don't create Visual Scenes. Something at a further stage of the processing seems to be creating the actual Visual Images that we see when we are Dreaming or when we are Awake.SteveKlinko

    It is true that we do not have a proof about the activity of rods and cones in the retinas during the REM. For that, we would need a human subject + fMRI... :)

    However, we are running in circles... :) Despite all of the evidence that there is no a totality of visual experiences within the brain -- you are coming back to your hypothesis... :)

    Now, give us a proof that the totality of visual experiences is hidden somewhere in the brain... :) But, that's rhetorical... :) I'm sure that you will not find a paper... :)

    Alternatively, consider a reverse path of signals from the rest of the brain --- to the retinas during imagination or sleep... :)

    There is no paper on how Consciousness is produced from the Neural Activity in the Brain. The Retina is just an extension of the Brain and the Rods and Cones are specialized Neurons. If your speculation is that the Visual Images that we see are strictly generated by the Retina then the question is how does the Retina generate the Visual Images that we see? That is the Hard Problem of Consciousness.

    While we are awake, the retina does not generate images. It simply contains the totality of visual sensations. Retinal pre-processing turns this totality of visual sensations into abstracts of "what is what" giving us the fast and pretty accurate navigation through the infinity of visual impressions... :)

    While dreaming (REM) this is reversed. The rest of the brain generates abstracts of "what is what" sending them to the retinas. And the retinas provides the rest of simulated visual experiences... :)

    While we are awake, consumption of hallucinogens (like mescaline, for example) reduces the impact of abstracts of "what is what" resulting in an overwhelming infinity of visual impressions. (See "The Doors of the Perception".) :)

    But when I look at a particular scene in front of me How is that Scene Image presented for me to See it? It appears that the scene I am looking at is painted on a kind of Screen that is embedded in the front of my face. All the Colors are painted there and are overlaid on top of the Physical World scene that I am looking at. The painted Image is a very good representation of the Physical World scene. I am looking at a Surrogate for the Physical World scene that is created by my Conscious Mind. Also what is the "I" that is Seeing that screen? These are the Deep Philosophical questions that we need to answer.

    When awake, visual sensations have many layers... :) The most fundamental is an infinity of visual sensations, but without "what is what". In other words, we are lost, without "what is what" layers... Subsequent layers are "what is whats" - that dull the infinity of visual sensations...

    I read articles summarizing the Book. I know that's not like reading the whole book, but I got a good feel for the book. I did not see from the summary at least how the book was going to solve the Hard Problem. The book just talked about enhanced perceptions and philosophical realizations. Could you possibly give a summary of How the book explains the Hard problem? The Hard Problem is: How does the Neural Activity (using drugs or not using drugs) produce the Conscious experience?

    The hard problem of consciousness is the problem of qualia or Husserl's hyle?

    There is simply a prior, non physical, phenomenal aspect that no understanding of the physical will ever give rise to: for such an understanding would have to suffice to replace it, which is utterly impossible, and is completely incommensurate with its object, and is bombastic in even a consideration.

    This is not said nowadays because people are scared of being called a theist or, even worse, NOT ATHEIST! HOW SCARY!

    As if such a statement says anything further!

    Quite correct. But I still think that the non-Physical will be understood by Science someday if only they would sit back, relax, and think more Deeply about it.

    What bothers me so much is this aversion to what cannot be empirically distinguished, such to be defined like an atom can be, or a neural impulse. It is really sad; this pop-atheist, pseudo-philosophical simulacrum disguised as philosophical discourse today. And I'm talking about Dawkins, Sam Harris, Daniel Dennett , and others. Many others. Its just tasteless.

    There is visual stuff when you close your eyes. They are called phosphenes. Have you heard of this? I, personally, have a theory about how sleep begins, with regard to phosphenes, and subjectively I have proven it, because it always works.

    Again. Neural activity does not produce conscious experience. But, we are getting back to neuronal activity (not retinal activity) again --- as if we never discussed it. I will, therefore, stop repeating myself... :)

    I may have forgotten to mention that the Rods, Cones, etc. of the Retina are considered to be specialized Neurons. The Retina is just an extension of the Brain and so you can say that the external Light impinges directly on the Brain. It's all just Neural Activity. You want to give more importance to the Retina and that's ok and may be true. Neural Activity and the Conscious Visual experience are two different Categories of Phenomena. How does the Neural Activity of the Retina produce a Conscious Visual experience?

    We do not See things in the external World, but rather we Detect things by using internal Conscious processes that we are born with. We all have a personal Conscious Light Screen (CLS) that we use to detect what is happening in the external World. If we try to describe where this CLS is located it seems to be embedded in the front of our faces in some way. The CLS is vaguely horizontally rectangular with ambiguous edges that are hard to locate exactly. The screen seems to just fade into nonexistence at the borders. But wherever you look, that screen is there showing you with Conscious Light what is in the scene you are looking at.

    To understand this better close your eyes and observe what you See. At first there may be various After Images that represent remnants of what you were looking at, but eventually these fade away. What is left is not totally black. Note that you might have to put your hand over your eyes if you are in a bright place in order to cut off external Light from leaking through your eyelids. Most people will notice a background that has a vague grainy noise almost like the video snow noise that used to appear on old analog TVs. Let's call this Conscious Light Noise (CLN). This noise effect is also called Phosphenes. It is due to random Retinal and Cortical firings. CLN really is the background noise in your Visual detection system. Most people easily perceive that this CLN, and possible After Images, are close to the front of their faces. If you move your head around you will See the CLN, and After Images, move around with your head to keep them in front of your face. If you move your eyes up, down, left, or right, the CLN and After Images will seem to be displaced a little in those directions but will still basically be located in front of your face. It is interesting to note that After Images will always look close even if the scene element that caused the After Image is far away. Now you know where your CLS is located.

    When you open your eyes the scene that you are looking at is painted onto your CLS and it is harder to perceive that the Conscious Light making up the image is still close to your face. Your Visual system tries to give you the illusion that there are things that are far away and things that are close. If you look through only one eye the depth illusion is less pronounced. But the Conscious Light that the scene is painted with is actually still located close to your face and is at the same distance as the CLN. The illusion of distance is absolutely necessary for moving around in the World.

    It should be mentioned that the things and scenes you See while Dreaming are also painted onto your CLS. The CLS is a general purpose Visual Display Device for all Conscious beings, whether Human or Animal. We walk around all day long looking at our CLSs which are embedded in the front of our faces. We cannot See the CLSs of other people but if we could it would be as if everyone was wearing Virtual Reality goggles. But instead of goggles it would be Conscious Light Screens. We think we are Seeing the external World directly but we (our Conscious Minds) are always just looking (in some Conscious way) at our own CLSs.

    You should see the phosphenes when you close your eyes in darkness while your brain is on LSD or psilocin, or any psychedelic substance. Extraordinary colors, patterns, fractals, zooms, geometry... Even colors that you never see otherwise.

    Actually - I said that... :)

    There are two effects of the retinal activity. The totality of visual experiences and hints and edges that travel through the optical nerves to the rest of the brain... :)

    How does the Neural Activity of the Retina produce a Conscious Visual experience?SteveKlinko

    Neural activity does not produce a "Conscious Visual experience"... :) Only a combination of the totality of visual experiences and retinal activity (sketchy images) produce a "Conscious Visual experience". For example: If we are born blind there would not be "Conscious Visual experience"... :)

    When we are born - we are almost blind and need to learn "what is what"... :)

    When the "what is what" is diminished (under the influence of a drug, for example) the totality of our visual experiences dominates... :)

    Without LSD I can See some things that are more than random noise. For example I can See Vortices where there will be a small circular section in the Phosphenes spiraling around and into a center. This is usually after dozing off for a moment so it is probably partially a Dream experience.

    exactly! I have seen what you have seen without any mind altering substance as well. But I will remark again on the extraordinary effect the safe psychedelic substances can have on perception and experience, as well as the brain, which already have endogenous hallucinogens and hallucinogenic tendencies that represent certain neural components, neurotransmitters and synaptic receptors whose function and effect are correlated with a fine mechanism of consciousness, feeling, sensation and understanding. But I degress.
    These light shows as I call them represent an extraordinary system, display or paradigmatic system of consciousness and organic life. They are amazing and the beauty they show of our own very experiences makes life ever more fascinating.

    You are still saying that the Neural Activity happens and that Explains everything. It is mind boggling to me that you cannot realize the thing that is missing in your explanation. The thing that is missing is the Red experience itself and the 440Hz Tone experience itself.SteveKlinko

    >From my perspective, once the mechanical process is outlined, something is explained. I think we've gone through this cycle of disagreement before, but I get the sense you want or expect something more than an explanation of function. I believe that's all there is, and different conscious experiences just seem so extravagant and profound, that its hard for our minds to except an explanation.
