Looks like we'll go around and around about this,so I'll reiterate the points that I feel have been glossed over so far before we go on:
1.DD's eliminative materialism denies that qualia exist.This is self contradictory because he tries to explain them.If they don't exist there is nothing to explain.
2.The term "illusion" is meant to be something false and unreal.
But:
If only material brainstates are real and an illusion is really a brainstate then illusions are real.
Unless:
There can be false or unreal brainstates
An extra comment:
Of course there is such a thing we call an illusion but they are still real conscious experiences no matter what the philosophy.A brain has it's place in the causality of an event that we call an 'illusion' ..but so does the world in what ever it's true form may be.Just as there is no finishline in the brain (something I agree about) there is also no starting line in the world that we can pinpoint either without being arbitrary.If you're open to explanations for illusions in a context other than a prop to support materialism, I recommend reading here:
Illusions are experiences that exploit nature's rules for construction of the world:

3. I wrote earlier:
Why should some event determined at the big bang match the 'illusory' sense of will at any particular moment? If it is an illusion then nature should not care.And like I said an illusion (internal) should have no ability to affect brain matter if we're consistent....So there's no reason for nature to evolve or naturally select such a glucose wasting brain function.An organism needs only to respond to it's environment in the rightway,reflexes will do just fine for this,no need for consciousness or illusions of agency and will....
To be clear,above I use the word illusion in the sense that you and DD use it as something false.
OK there's alot to respond to,I'll start with what jumped out at me:
SL:
"Brain damage in different areas can often result in the loss of different conscious experiences... loss of types of recognition etc. etc. "
Jeff:
This is true.This is another subject but I'll say for now that consciousness can be the knower of a damaged brain.Consciousness and it's content could be distinuished.
SL:
" An example is when you touch a boiling hot pan and your hand instantly moves away. The reflex action is unconscious. "
Jeff:
Dude,this is a spinal cord reflex so that's a total strawman! Nobody believes the conscious mind is responsible for that behavior.However,there is a sense of ownership,which is a separate issue.
SL:
"It's pretty simple. Inside a computer, you examine the circuitry and you won't find any evidence of pictures, films and the many other forms of data that it has saved. Yet, when you turn it on, the screen will show a clear picture (translation/interpretation) of what is being stimulated inside (and electricity is making all the difference). The brain is just a more advanced computer - a supercomputer - of a biological nature."
Jeff:
And is a computer aware of it's content and meaning? How does consciousness, a sense of self and freewill emerge from an arrangement of hardware or electricity? Why should this be an article of faith? If a brain is a computer then all of nature is too.This still leaves qualia and consciousness to be explained.
SL:
"It could be that they don't represent themselves in a similar way that a computer won't represent its binary code unless you tell it to. The codes, instead, are assigned to represent many meaningful associations and the relevant concepts arise."
Jeff:
Yes,minds create the code and assign meaning.We tell computers what to do.You almost make my point.... and concepts arise in mind.Neurons and electrochemicals do as the laws of nature compel.We exploit these laws to outsource information processing.
SL:
"Quantum mechanics are not necessarily required even though many seem to think so. We don't yet understand enough of quantum mechanics so that is also moot."
Jeff:
Fair enough.But any complete picture of reality must ultimately include QM.To say that it doesn't apply to macro objects is just not true.There is a "correspondence principle" and QM is the most successful theory of matter and energy.It is certainly relevant if certain interpretations have ontological status.
SL:
"Only there is no little green man... "
There is no 'green' except in the mind.Green is real.
SL:
"The brain bases its best guess of what is going on in the world on the information it is currently receiving from the senses. When asleep, the brain acquires little information from the senses. Therefore, the information most readily available is what is already inside our heads - memories, expectations, fears, desires, and so on. I believe that dreams are a result of our brains using this internal information to create a simulation of the world."
Jeff:
I believe this is a complete mischaracterization of reality.I'd like to make a post all it's own on this one..LOL! In a nutshell this would require neurons to be intrinsically creative,not to mention the representation and self reference problems.And as I said,they act as the laws of nature compell them to.Futhermore this is false.I have experienced veridical content in the phase that was never entered through my conventional senses.Of course you and DD are both free to ignore this.
