Trivial in the technical sense of not being as real as the objective mechanics which are associated with them. You are saying that it's only the high quantity of neurons and connections between them that makes them real rather than the other way around. To say that subjective qualities are non-trivial would mean acknowledging that it is the subjective qualities themselves which are driving cells, neurons, organisms, and cultures rather than just mechanism. You are saying that hydrogen is non-trivial but yellow is one of an infinite number of possible colors. I'm saying that the visible spectrum is as fundamental and irreducible as the periodic table, even though it may require a more complex organic arrangement to realize subjectively. >Yes, as you say below, it is a result of processing.

Yellow is not a computation. Discerning whether something is a different frequency of luminosity than another is a computation, correlating that to a sensory experience is a computation, but the experience itself is not a computation. I can give you coordinates for a polygon and you can draw it on paper or in your mind but giving you the wavelength for a shade of X-Ray will not help you see it's color or create a color. It doesn't matter how complex my formula is. Color cannot be described quantitatively. It's not a matter of waiting for technology to get better, it's a matter of understanding the limitations of the exterior topology of our universe. >Right, a youtube video is not a person, but I think silicon, or any >appropriate processing system can perceive. I think that anything can perceive, whether it's a processing system or not. Not human perception, but if it's matter, then it has electromagnetic properties and corresponding sensorimotor coherence. All matter makes sense. It's just that the sense the brain makes recapitulates a specific layer cake of organic molecular, cellular biochemical, somatic zoological, neuro anthropological, and psychological semiotic protocols which are not separate from what they physically are. You can't export the canon of microbiological wisdom into a stone unless you make the stone live as a creature. It's not third party translatable. If it were, then every rock and tree would by now have learned to speak Portuguese and cook up a mean linguine with clams. >If red did not look very different from green, to you would fail to pick out >the berries in the bush. That's a fallacy. First you're reducing red or green to a mechanical function of visual differentiation. Such a definition of color does not require conscious experience or vision at all. The bush and the berries could just look like what they taste like. Why create a separate perceptual ontology? You're also reverse engineering color to match the contemporary assumptions of evolutionary biology. We have no reason to suspect that selection pressure would or could conjure a color palette out of thin air. A longer beak, yes. Prehensile tail, sure. You've already got the physical structure, it just gets exaggerated through heredity. Where is the ancestor of red though? >Yes information must be interpreted by a processing system to become >meaningful, but it doesn't have to be a biological organism. Systems don't interpret information, they just present it in different ways. It makes no difference to a computer whether a text is stored as natural language, hexadecimal bytes, or semiconductor states. There is no signifying coherence on the computer level, it's just an array of low level phenomena being used to simulate and reflect high level organic sense. You might be able to build chemo-electronic inorganism which feels and has meaning, but my sense is that it would end up being no more controllable than biological entities. What we want out of a processing system - reliability, obedience, precision, etc, is precisely what is lost when we want to traffic in meaning beyond digital certainties. >> Constructed out of what? >Information and the processing thereof. You cannot construct a color out of information, any more than you can construct dinner out of information. Color is concrete sensory experience - ineffable, idiopathic, self-revealing. There is no information there, no recipe, it's an ontological prerequisite of biological visual sense. >> Why can't we just imagine a color zlue if >> it's not different than imaging a square sitting on top of a circle? >Our imagination does not cause the organization of the color processing >centers of the brain to rewire themselves. If we could rewire our brains we >could experience new colors. If color is purely a mental phenomenon, then why should it require any rewiring? We can only experience new colors if there are new colors to experience. Color could just as easily be as finite and specific as the periodic table and emerge at the subatomic level. We may well be able to see new colors with gene patches or neurotherapies, but it doesn't change the fact that those colors too must be either be part of a larger fixed ontology of possible colors or part of a dynamic color creation schema. Either way it's metaphysical unless you model sense as a function of matter. >You are making assumptions of a direct chemical-to-qualia relation built >into the physics of the universe. It's not an assumption, it's an intentional hypothesis. >You never addressed the evidence I gave regarding how magenta is an invented >color. All colors are invented. Just not by us. Magenta, brown, beige, grey, etc are further evidence that color is not simply visible electromagnetism - it is the sensorimotor interior of electromagnetism. It makes sense to us that black should be the absence of light and white should be the presence of all wavelengths. That sense runs through both sides of vision - the optical exterior and the perceptual interior. It doesn't have to be that way. Black could look like orange and White could like like red-orange and we'd still be able to tell the difference. Black vs white though makes a specific visual sense to us. To anything that can see it. >See this video: >http://www.closertotruth.com/video-profile/What-is-the-Mind-Body-Prob... Ugh. Minsky is wrong. Just because there are more steps involved in perception doesn't bring the mechanism of neural spikes or ion pumping any closer to the experience of perception. He's using complexity as a veil. "Your poor little minds just haven't figured it out yet." It's not complex, it's just looking at the phenomenon from the wrong end. He doesn't see that perception doesn't have to correlate to the mechanics of the brain directly, they both can correlate to different sided of an underlying noumenon. Watch David Chalmers instead. His insights make much more sense to me: http://www.youtube.com/watch?v=kmZaA_xoJiM >We can perceive millions of different colors, but there are not millions of >types of neurotransmitters, nor millions of types of neurons. How does your >theory address this? I'm not suggesting a one to one correspondence of neurotransmitters to colors. I'm saying that the sense of the visual spectrum as we know it is an innate potential of human neurology at the brain level. It may arise at a lower level - maybe at the level of photosynthesis or the level atoms - perhaps at a higher level of astrophysical coherence; nebula etc. Maybe it's woven into the story of the cosmos itself, in the fabric of what separates literal fact from metaphorical meaning. >What, aside from their parts, is different about them? What's the difference between you reading this and being in a coma? What if I could offer the chance for you to have a perfect body, which will not age or die, which will have powerful extensions of physical ability, but there is one catch. You will never be able to experience a single moment that is not filled with blinding, shrieking pain. You will perceive yourself to be terrifyingly ugly and your world will be filled only with the most revolting odors and noises. You will find that you are able to eat and reproduce quite successfully, only your experience of it will be as gagging and writhing in interminable nausea. All you would have to comfort you in your unending, pleasureless misery will be the knowledge that to the outside world you will appear to be a fantastic human being, successful in all areas, even that thought however, will repulse you and fill you with bottomless dread. I'm assuming that you would agree that such a deal would not be worth it, but can you explain why? Why privilege one set of patterns over another? That's what consciousness gives us. Sensorimotive participation. A way to perceive qualitative differences and feel like we can choose to move toward or away from them. This is the basis of life as much as ATP or DNA, but an entirely different topology: forward and back, high/low, right and wrong, pain and pleasure, presence and absence. See?
