could it be so simple ?"
I think that it could be so simple, Ringo. Although I don't necessarily agree with some of your details or descriptions.

" To me the real question to ask is this; why it is that neither of us (and nobody else) can prove our case about the relationship between consciousness and brain?"
I think it is because we are making some false, implicit, unacknowledged assumptions. Some of you assume that there is nothing in reality outside of the physical world, and most of the rest of you assume that consciousness, if not actually seated in the brain, is associated in a more-or-less one-to-one relationship with the brains of live humans as well as maybe some, or many, other animals.
I propose that we consider both of these assumptions to be suspect, deny them, and then try to come up with a hypothesis that might offer answers to all the questions you have been debating in this thread. I have made a modest attempt to do that and I'll try to explain it here.
Along the lines of Ringo's proposal, I propose that consciousness is something completely separate from the physical world, that comes into contact with the physical world via brains. (I am indebted to Gerben for this particular wording.)
Gerben said:
" You propose that consciousness is something completely separate from the physical world, that comes into contact with the physical world via brains.
ok
and then?"
And then we proceed to flesh out the hypothesis. In order to be clear about what it means to be separate from the physical world, we must be clear about what we mean by 'the physical world'. For the purposes of this post, let me define the physical world to be the familar 4D space-time continuum which is more-or-less accessible to our senses and instruments, along with its contents of fields and/or particles which might be there. Now, if string theory is correct, and there are additional dimensions, then we would have to discuss whether or not the extra space-time which comes with them is also part of the physical world.
This is strictly a semantic question. If we say that all those extra dimensions are part of the physical world, then if indeed consciousness were seated in those extra dimensions but not present in our 4D space-time, then we would have Ringo's conditions, consciousness would be inaccessible to conventional experiments, and yet consciousness would still be part of the physical world.
If we say that those extra dimensions are not part of the physical world, then we are denying the truth of string theory without any real justification for doing so.
Either way, my proposal is that consciousness is seated, i.e. resides or exists, wholly outside of our 4D space-time continuum in some sort of space-time environment spanned by extra dimensions. (Incidentally I think that those dimensions are astronomically large and that there is no cogent reason to suppose that they are curled-up, as they are commonly considered to do. I have discussed this point in another thread and received no convincing rebuttal.)
Next, I propose that consciousness comes into contact with brains in a way similar to the way in which a human listener comes into contact with a human speaker. Or in a way similar to the way in which two cell phones come into contact when a call is established between them.
In all these cases, the contact is established via some sort of wave that propagates information transfer between the two parties to the communication. In the case of speech, the waves are compression waves in air; in the case of the cell phones the waves are EM waves; in the case of communication between consciousness and the brain I can only guess. My guess is that, in the environment offered by those additional dimensions, there may be additional fields, analogous to electric, magnetic, or gravitational fields, which serve as the medium for the waves. The analogy doesn't have to be very close but instead it might be something completely new, just as the probability density waves of QM aren't very much like the familiar EM or sound waves.
In short, I see the brain as analogous (try to imagine a diagonal frog) to a cell phone. Cell phones these days can produce not only sounds from a distant source, but also images. It's not much of a stretch to suppose that the cell-phone-brain can not only transmit perceptions to the remote consciousness, but also receive willed instructions from consciousness which initiate and drive physiological processes such as muscle movement and hormone secretions.
In other words, living bodies are physical vehicles which are driven by a remote consciousness with a two-way communication path allowing for the consciousness to perceive the sensory impressions of the body and for the consciousness to deliberately cause willful and purposeful activity of the body.
I think this proposal suggests answers to nearly all the hard questions being discussed here. What I would like to solicit is any cogent reason why this proposal could not be true. In the meantime, let me take on some of those questions.

"What is so special about the particular arrangement of matter in our brain that prohibits simulation? We could simulate a pendulum, a solar system, gas in a container, but not this? Why?"
The same thing that prevents the simulation of a cell-phone by, say, a Martian who might have taken one of ours back to Mars to investigate it. Without the working cell-phone system of towers, transponders, relay stations, and EM field, not to mention another cell-phone on the other end with someone to talk to, the Martian investigator would get nowhere examining that cell-phone in all its detail down to the quarks and leptons.

Good point! Take a cell-phone slice and examine it the same way and show me a sound or the residue of a conversation, please.
StatusX said:
" Just on a side note, those of you who claim all these functions of the brain, like knowledge, thought, etc., are a result of non-physical consciousness: what is the brain for?"
The brain is a communication device that connects consciousness with a body. It performs the same vital function as the transponder and computer inside a UAV (I think that's what they call those remote controlled airplanes) that enable a pilot many miles away to "fly" the airplane and be aware of what the airplane is doing and what the environment looks like from the perspective of the airplane.
StatusX said:
"All that happens is photons hit our eye and cause a chemical reaction which causes electrical impulses in our brain. These impulses gives rise to conscious experience. I think the brain is the only place we should look to if we want to find the cause of consciousness."
I don't think that's "All that happens". I think you will have trouble trying to explain the "gives rise to" part. I think that looking only at the brain to explain consciousness is like looking only at one cell-phone in order to explain its function and capability.
Fliption said:
"If we cannot explain how the brain produces consciousness then how the hell are we going to explain the how the brain produces the illusion of it? I'm not even sure what the difference is. It seems the same problems remain. I always thought certain aspects of illusions were a function of consciousness to begin with. How can you have an illusion without consciousness? Who is it that is experiencing the illusion? And how do they experience it if consciousness is just an illusion? This one just seems messy to me."
I think my proposal clears up the mess completely. First, we cannot explain how the brain produces consciousness because it doesn't. Now the brain probably (in fact I think almost certainly) can produce illusions simply by distorting some of the sensory perceptions before transmitting them to consciousness. As you point out, only consciousness can experience an illusion. In my view, the illusion that is going on here is that consciousness, in some circumstances, has the illusion that it is seated in a human brain. In the same way, I suppose that the remote pilot of a UAV during a period of intense concentration on an intricate maneuver might seem to be actually seated in the airplane.
Olde Drunk said:
"Consciousness is the ability focus my mind and or spirit on my experiences."
I agree. In my view, however, we have to be careful about the use of the word 'my'. In my scheme, mind, spirit, and consciousness are all remote, not only from the body and brain but from the physical world itself. The experiences, on the other hand, happen to the physical body but are known only to the consciousness.
Les Sleeth said:
"I believe as experience integrates, it establishes a non-intellectual certainty with past events we call knowing. "
I agree. It is the consciousness which knows the past events of experience.
Les Sleeth said:
"So experience is what we are talking about that defines consciousness, while awareness is simply the ability to detect information."
Not quite -- in my scheme. I haven't yet defined 'consciousness', but I would say that experience is the history of a body as reported to, and perceived by, consciousness. Awareness is the ability of consciousness to know that history, and, yes, consciousness acquires that knowledge by detecting information transmitted by the brain.. (I deliberately left out the word 'simply' because I consider this ability to be profound.)
Les Sleeth said:
"Experience is self awareness, that is the definition of experience. That's what you can't explain functionally, physically, etc."
I agree that you can't explain experience or self awareness functionally, physically, etc., but using self awareness as a definition of experience begs the question of what we mean by 'self'.
Les Sleeth said:
" It seems to me that this integrative quality of consciousness is what most establishes self, or subjectivity. (A computer can do all the rest, but not that.) Examining humans, it seems there is a very high realization of the integrative thing because we can function single-pointedly doing complex tasks. It's like all that's integrated into consciousness is right there guiding the focused human even though he might not be thinking about everything that's contributed to his knowing pool."
I agree. I think you put it well. In my view, however, keep in mind that the integrative quality and consciousness itself are outside the brain and the physical world.
Les Sleeth said:
"I say there is no possible way to know anything without being conscious...The experience of knowledge is precisely what we are talking about."
I agree. In fact, if I had to pick the one attribute which I think most completely describes consciousness, I would say it is the ability to know.
Les Sleeth said:
"The integrative function is absolutely the most crucial factor of consciousness because it creates the singular aspect which comes to control, oversee, know . . . and one of the things it "knows" is that it exists! That is what self/subjectivity is: self knowing."
I agree completely. I like the way you put it. I especially like your choice of the word 'singular'. It suggests what I think is an important question: How many distinct consciousnesses are there? Is there one for each living brain? Is there one for each brain that ever lived? My answer is that, no, there is only ONE consciousness in all of reality. That one consciousness drives all the bodies of all organisms and always has.
StatusX said:
"But what if you could create some kind of link, so that you could access any part of their brain, and they could do the same to you? I think any separate individuality would disappear, and the consciousnesses would merge into one. This is highly speculative, and I don't expect anyone to buy it with what little argument I've provided here, but I just thought of it and I'm still working it out. Basically the conclusion is, there is only one consciousness, but it is divided up among the different systems. If you could join the information flow of two systems, the separate consciousnesses would disappear, and if you could somehow join all systems, there would be one consciousness remaining. Well that's all I have for now. I'll try to build on this (or realize how wrong it is) later."
I think you're close here, StatusX. In my view, your first sentence would make sense if by "you" you mean the one consciousness, and by "their" you mean individual human bodies. Then the answer to your "What if" question is that you would get something very like my proposal. You would get a single, non-physical consciousness accessing and communicating with organic brains via some kind of link. And, with this mechanism, the consciousness would be in a position to deliberately drive each organism through its history of physical experiences.
In this case, as you say, any separate individuality would disappear, not that "consciousnesses would merge into one", because there is only one consciousness. There would still be individuality among the various human bodies, but there would only be one self if by 'self' we mean qualities or attributes of consciousness.
Anuj said:
"To understand consciousness, we first need to understand how do we ourself work. Human brain is that biological body part which drives our life"
I agree with both assertions. I'm not saying that I understand how our self works, but I think that my proposed hypothesis provides a way to come up with a logical and believable explanation.
Les Sleeth: "Introspectionists should make sense."[/QUOTE said:
I'll try to make sense of this explanation. Just as in a cell-phone, there is some specific part of the structure which generates the EM radiation which encodes outgoing information, and another specific structure which can detect incoming information from EM waves, there are probably corresponding structures in the brain. And, just as in a cell-phone where you would be able to locate and identify those specific circuits without the involvement of EM radiation, I think it should be possible to locate and identify specific structures in the brain which generate outgoing signals and which detect incoming signals. In my view, Hammeroff and Penrose have suggested the most promising possibility. I think the "antennas" are the dimers in the microtubules in the neurons. These little things can flip between two stable states in response to the local state of nearby dimers, but more importantly, in response to supposedly random quantum events. In my humble opinion, and I think this is in line with what Einstein thought, these events are not truly random but instead can be influenced by some hidden variable. I propose that the hidden variable is the deliberate action of the one consciousness which causes certain waveform collapses to occur in such a way as to start a cascade of classical particle interactions starting with the subatomic constituents of the dimer atoms, and ending with the flexing of muscle cells. Of course, it continues beyond that to, say, the pressure applied to the accelerator pedal, but those consequences are well known.
StatusX said:
" One way around this is to say that these random collapses aren't truly random, but are affected by our consciousness. This is a very interesting idea, and I definitely accept it as a possibility."
Hmmm. Sounds like there is a possibility you might buy into part of my proposal, StatusX.
