    The argument that consciousness is an illusion actually has some interesting subtlety to it that most people miss when hearing about it.

    The claim is that our introspection misleads us into attributing phenomenal feels to experience. It seems like we have the ineffable, intrinsic, private and immediately apprehended qualia which is so hard to reconcile with any scientific account. But instead what we have is a quasi-phenomenal redness of red. The quasi part means a distortion of the actual biological mechanisms which create experience. It's a simplification of a complex process represented in a way that seems phenomenal.

    This means that the philosophical zombie argument is mistaken, because there would be something it is like for a zombie, which is the illusion of having qualia. However, zombies are supposed to be "all dark" inside, so the zombie thought experiment is making a mistake which a better understanding of neuroscience would show to be impossible. If the zombie is physically the same us, it undergoes the same illusion about being conscious. The what it's like is introspection telling the zombie there is something it's like to see red or be in pain, and that introspection is itself a functional process. Thus, illusionism is not denying there is something it's like. That's the illusion.

    This argument also has a good reason motivating it. If we do actually possess phenomenal consciousness, then how do we know about it? How is it represented in memory, and how do place it into language? Those are understood to be neurological functions. Which would mean the qualia is somehow being accessed by the brain. Wittgenstein's beetle-in-the-box deserves a shout out here as well.

    The advantage of illusionism over outright eliminativism is that it acknowledges we do very much seem to have these rich phenomenal experiences, leading to the concept of qualia. But our introspection is unreliable. Colors, sounds, feels, etc. are useful fictions consolidating an overwhelming amount of information and processing into something an organism can easily act upon. And this is why consciousness seems to be so hard to explain.

    The remaining difficulty for the illusionist is providing the mechanism for the introspective illusion of qualia. Which presumably neuroscience will uncover at some point, if the position is correct.

    I'm loathe to use terms like "fiction" and "illusions" when it comes to consciousness. I don't understand how a "fiction" is useful for anything but entertainment, and a mirage would be an illusion within the "illusion" of consciousness, which doesn't make any sense. How does natural selection filter out or promote these introspective fictions and illusions? Are there "fictions" and "illusions" that are more useful than others? How and why? To say that one "illusion" is more useful for survival is saying that it is less of an illusion than some other concept. For something to be useful, it has to have some sort of connection with real states of affairs in the environment.

    How does the brain introspect, and when a brain introspects, why doesn't it experience an arrangement of excited neurons rather than the qualia of colors, shapes, sounds, etc.,? Does it make sense to say that a brain can think about thinking? If it can do that, then is "thinking" (I think therefore I am) an illusion? How do you know where the illusions stop and reality begins to even say "I think, therefore I am"?

    Good to know about this analogy. I had always thought of the subjectivity of experience, mostly of colour and that there was no way to deduce that my image of colour green is remotely similar to someone else's image of the colour green.

    This is what I would choose as an alternative to functionalism and panpsychism ; that consciousness arises from the processing of huge amounts of information in the brain. It is intuitive and won't lead us to conclude that everything has some essence of consciousness. The obvious problem however, is that we don't have the slightest of clue how such a process results in the experience of qualia

    I'll second here. You'll have to first define illusion in a way that makes sense when inside the mind. What's the difference between experiencing the illusion of qualia and experiencing qualia themselves? What difference does it make in any practical capacity?

    The what it's like is the illusion that we have qualia. So we are having an experience that seems to be what it's like in the sense of the hard problem. It's a powerful illusion.

    I admit this isn't entirely convincing. The crux of the argument is whether one can present this in a way where the illusion isn't itself phenomenal.

    But what it is doing is attacking the notion that we can just take our introspective judgement of consciousness at face value. What if we're wrong?

    I hear this a lot. But I wonder how, and even whether, it is meant to deflate qualia talk and Cartesian theatre talk. A visual interface is pictures we look at, and locating them in the head implies a homunculus to view them, whether or not they are to be read as depicting realistically or figuratively.

    Kind of an own goal.

    True, but it's also being used as a metaphor. Illusionists aren't saying there's literally a computer-like graphical display in the brain. Also because vision is just one of the senses, and we should be mindful not to base too much philosophical argument based on vision alone, as that can be misleading.

    However, to your point, I do wonder about dreams and day dreams, which very much seem like a theater or movie playing in the head. It's weird to me how the hard problem is super-focused on perception, when I think the hardest part is the non-perceptual experiences, because those aren't originating from outside. A dream is almost entirely a product of the brain (setting aside occasional external stimulus making their way into the dream). And that presents a problem.

    That's more of a model, or representation. I don't think "illusion" or "fiction" would be the proper terms to use here. The illusion would be to mistake the representation for reality, just as a mirage is to mistake the behavior of light over a heated surface for a pool of water.

    and a mirage would be an illusion within the "illusion" of consciousness,

    Marchesk

    Illusions are a mistake in judgement, or the wrong interpretation. The qualia that create the mirage is real. It is what you would expect to see if we see light, not objects (just as we see bent straws in water - we see light, not the actual objects). The part of the mind that interprets the qualia uses past experiences to interpret current experiences. The mirage looks like a pool of water and is interpreted as such - hence the illusion. The illusion is broken when you realize that the pool of water moves and your past experience is that pools of water do not move. More observations make better interpretations. Visual illusions are usually based on the mind believing that it is seeing objects and not light.

    Inference to the best explanation, given the overwhelming data from studies, experiments and various medical cases we have now.

    Science is not compatible with the world being colored in, full of sound, feels, etc. But this was known to an extent in ancient philosophy. Full-blown naive realism just cannot be the case. Now maybe a sophisticated version of direct realism can work, but not one that places our perceptual sensations out there in the world.

    Marchesk
    This is a contradiction, as I was trying to point out before. If you're going to claim that our mind is an illusion and that naive realism cannot be the case, then how can you even claim that brains exist, as brains are concepts that stem from our experience with the world? You can't have your cake and eat it too.

    How can you even claim that science has provided answers if we don't get at the real states-of-affairs of the universe in some way? Direct and indirect become meaningless if we get at the answers of the universe. Effects carry information about their causes - no matter how direct/indirect the causal relationship is. Each effect carries information about all subsequent causes - just as your visual experience (the effect) carries information about the ripeness of the apple, the amount of light in the environment and the state of your visual system. The eye doctor asks you to read a chart that is the constant where each patient is the variable. The eye doctor isn't testing the light or the chart when he asks you to read it. He's testing your visual system, as the light and the chart are the constants.

    Why would the doctor reference your illusion to test your visual system?

    Our perceptual sensations are out there in the world if there are other minds. If you were to call them other "illusions" wouldn't make much sense. Those "illusions" have causal power. Think of Beethoven and Picasso.

    The self is is itself a useful fiction. Don't Buddhists consider it to be an illusion?Marchesk

    The short answer is: when asked straight out or not if the self existed, the Buddha would not answer (ref). This is because, He said, to answer 'no' would be to side with nihilists (which would include any of today's physicalists.) To answer 'yes' would be to side with the eternalists (who believed there was an eternal self that could be reborn in perpetuity.) But the subtleties of Buddhist dialectic is well outside the scope of the discussion.

    Look again at the question I asked - who is the 'I' or 'we' which any kind of illusionism posits is subject to illusion? Because, an illusion is a mistake, right? Illusion only exists in contrast to reality, it is something that only exists in a conscious mind; there are no illusions possible outside that domain. It implies a mistaken judgement.

    And this is the contradiction at the basis of any such arguments: they want to say that what is real, is only the neural systems that give rise to 'the sense of being'. But the being that is the supposed 'illusion' is the only one who can make such a judgement!

    I've probably already posted this Schopenhauer quote about it, but it can't hurt to say it again:

    [Materialism] seeks the primary and most simple state of matter, and then tries to develop all the others from it; ascending from mere mechanism, to chemism, to polarity, to the vegetable and to the animal kingdom. And if we suppose this to have been done, the last link in the chain would be animal sensibility - that is knowledge - which would consequently now appear as a mere modification or state of matter produced by causality. Now if we had followed materialism thus far with clear ideas, when we reached its highest point we would suddenly be seized with a fit of the inextinguishable laughter of the Olympians. As if waking from a dream, we would all at once become aware that its final result - knowledge, which it reached so laboriously, was presupposed as the indispensable condition of its very starting-point, mere matter; and when we imagined that we thought matter, we really thought only the subject that perceives matter; the eye that sees it, the hand that feels it, the understanding that knows it. Thus the tremendous petitio principii reveals itself unexpectedly. — Schopenhauer

    'Petito principi' is a fallacy in which a conclusion is taken for granted in the premises; begging the question.

    This criticism applies to all such arguments; once you realise this, you will not be able to entertain them any further. It is a mistake, as the ancient aphorism says, 'like the hand trying to grasp itself or the eye trying to see itself'.

    Our perceptual sensations are out there in the world if there are other minds.Harry Hindu

    "Out there in the world" is understood to be mind-independent. Naive realism assumes that objects have all the properties we perceive them to have, the way we perceive them. That has been shown to be wrong. The mind-independent world is not simply a reflection of our perceptions. Not unless you're a subjective idealist.

    How can you even claim that science has provides answers if we don't get at the real states-of-affairs of the universe in some way.Harry Hindu

    Of course I'm assuming science is providing answers based on some correlation with the real world. But there is a long standing problem of perception. Which is why skepticism never completely goes away, and people come to different metaphysical conclusions about the nature of reality.

    An indirect realist understands that objects have properties that our perceptions represent. If you understand causation, you understand that effects are not their causes. No, the apple isn't red, it is ripe. I get at it's ripeness (property of the apple) by experiencing redness (property of my mind). It doesn't make sense to talk about direct vs. indirect if I can get at the truth - which the state of ripeness of the apple. If you had direct access, and I had indirect access, but we both realized the apple is ripe, then what exactly is the meaningful difference?

    Think about this:

    How would camouflage evolve if visual experiences were merely illusions, or fictions, and didn't play a causal role in nature. Just as predators and prey have a causal relationship in each other's evolution, camouflage and visual experiences play a causal role in the evolution of better ways to avoid visual detection and better visual systems to detect hidden objects.

    The mind and "physical" bodies play a causal role in each others' evolution. In this sense, "physical" and "mental" categories become meaningless. It is all information.
