Posted twice, neither had got through by the time of posting which was at least 14 minutes after the second post, so started a new thread again. It is a continuation of:

Was it that having a look-up table where certain channel values relate to certain words for the purposes of communicating in whatever communication language the software has loaded would prevent it from ever being considered being conscious? If not, then why not assume that it performs whatever behaviour you think it would require. I'll remind you of the robot again.

It has cameras for eyes, with each pixel having three 8-bit intensity values (so a range from 0-255) each represent a colour intensity. These come through 3 channels A, B, and C. Internally, in software ("version 1"), the robot holds a table so to speak of linking words to the colour values. E.g. if channel A has an intensity of 255, and B & C intensities of 0, the robot will use the word "red" to describe the colour if B is 255 and A & C are 0 it will use the word "green" and if C is 255 and A & B are 0, it will use the word "blue" to describe the colour. You can imagine that all its reactions to colour are based off the ABC channel values.

From each pair, one is in a red room with a blue table, and the other is in a blue room with a red table. Do both the Mark 1s (the one with RGB camera eyes, and the one with BGR camera eyes) in the red room with a blue table experience the room with similar red qualia as you would, and the table with a similar blue qualia as you would?

After months and months of my and others trying to answer your questions, interpreting your questions, trying to make sense of them in the best possible light, getting diverted into pointless side issues, finally two or three of your arguments against physicalism have emerged from the mist. And all of them could have been stated up front in your first post. But whenever it becomes clear what you are arguing, and when people critique your argument, you just run off and take refuge in more pointless questions, rather than deal with the arguments that you've coughed up after so much labor.

A sufficiently large collection of components (hand raisers or random electrical gates) or a subset of the collection could, by chance behave exactly as the computer controlling a conscious robot. So consciousness could arise randomly, even say, among an enormous collection of people randomly raising their hands.

A human brain experiencing, say, the sensation of eating a strawberry cupcake, might be produced on an alien world, by an alien artist simply interested in producing a mechanism to control an artistic display of fairy lights, even though the alien knew nothing of humans. And it's obviously absurd that that brain could feel the experience of eating a strawberry cupcake when there are no humans, no strawberries, and no cupcakes anywhere to be seen.

When you say consciousness is not a behavior do you mean it is not something macroscopic and externally observable, like talking, running, grimacing, etc? If that's what you mean, then I agree with you. Or do you mean that consciousness is not something that is even in principle observable? If that's what you mean, then I disagree. Though in either case I'll have no trouble understanding what you mean, as long as you just come out and *say* what you mean.

You could presumably imagine the human in which there are no quantum events corresponding to such a mind/soul but which were just by chance. So the human behaviour was the same, but the explanation different. Whether you can or not I don't know. But if you can then the feature I am talking about are the sensations that the dualists claim are a feature of the mind."

You've asked me for an explanation, and I've given more than one, and that was yet another one. Regarding your first point, are you suggesting that non-dualists are incapable of understanding which features the dualists were suggesting were of the soul/mind and not features of the physical human, and that because you aren't a dualist you are therefore incapable of understanding which features they were?

There are lots of dualists, though, so just to be sure, maybe you should say which features exactly, you think are features of the mind/soul rather than features of the physical human.

All that was required from Penrose and Hameroffs' theory is that there exists a mechanism which allows quantum effects in microtubules to influence neural firing, things like quantum entanglement are irrelevant.

> Dualism, and the particular version espoused by Penrose are not the same thing. In any case Penrose's version still suffers from the problems that afflict all dualist accounts. How does the immaterial mind interact with material particulars to change their quantum behavior? All bringing in quantum mechanics does is hide the interaction between the matierial and the non-material a bit. If the non-material is non-material, how is it localized in space? Why does the mind only effect the quantum behavior of particles within the brain it is associated with? One can wave away all this problems, and if you are unsatisfied with physicalism, perhaps you have no choice but to wave them away, but the dualist account is no more complete than the physicalist account, and intoning the words "quantum mechanics" does not make it any more complete.
>
I didn't think Dualism and what was espoused by Penrose were the same thing. You had said that decoherence was a problem form Penrose's account, but with dualism you change the problem to how "the immaterial mind interacts with material particulars". I'm not a dualist. I'm a monist, in the sense that all there is is mind. I'm not a solipsist, I don't think mine is the only mind. Here is a post with a rough outline, it might not be that easy to follow, and isn't too relevant, other than to point out that dualism isn't the only alternative to physicalism. There is the other side of the dualism.

On my view the qualia of blue is the sum of the following behavior, the firing of blue-receptive cone cells in the retina, the transmission of that signal up the visual pathways, the integration of the color information with the shape and boundary information collected by the rods, the higher level visual processing involving identification of whatever it was that was blue, the modulation of the perception of blue by adjacent colors, the triggering of the word "blue," the associations brought up from memory of other blue things, the interaction of those memories with my current emotional state, any connections to thoughts I'd been having about anything that might be effected by seeing that blue thing. I could go on, but I suspect you get the drift. All those things are behaviors that my brain does in response to the sight of that blue thing, and that's the behavior that I would identify as a qualia of blue.

That is, I am not claiming that statements about sensations and mental images are reducible to or analyzable into statements about brain processes, in the way in which "cognition statements" are analyzable into statements about behaviour. To say that statements about consciousness are statements about brain processes is manifestly false. This is shown (a) by the fact that you can describe your sensations and mental imagery without knowing anything about your brain processes or even that such things exist, (b) by the fact that statements about one's consciousness and statements about one's brain processes are verified in entirely different ways, and (c) by the fact that there is nothing self-contradictory about the statement "X has a pain but there is nothing going on in his brain." What I do want to assert, however, is that the statement "Consciousness is a process in the brain," although not necessarily true, is not necessarily false.'

Having a first person perspective is what I mean by consciously experiencing. So I'd only regard something as consciously experiencing if it had a first person perspective.
So where I had earlier written
"(2) To you a philosophical zombie is something that is being imagined to behave in an indistinguishable fashion from a human while at the same time being imagined to behave differently, and so is just a plain contradiction."
And you in post
https://groups.google.com/d/msg/talk.origins/NRAe8H0KIjs/CUtF0JxeBwAJ replied: "That's correct."
I think you misunderstood what a philosophical zombie is. It would just be a human without a first person perspective. So using your analogy, there would still be the pyramid, but there is only a perspective from the side, and not one from the bottom. So the same behaviour, but no first person perspective of it. So no contradiction. Just an imagining of what the behavioural impact would be if a certain feature was different, in a similar way to how Stephen Hawking & Leonard Mlodinow mention that scientists have done with other features. They mentioned scientists doing such things in "The Grand Design" when they were commenting on Hoyles prediction in 1952 that the sum of the energies of a beryllium nucleus and a helium nucleus must be almost exactly the energy of a certain quantum state of the state of the isotope of carbon formed for resonance.
---
'Hoyle wrote, "I do not believe that any scientist who examined the evidence would fail to draw upon the inference that the laws of nuclear physics have been deliberately designed with regard to the consequences they produce inside the stars." At the time no one knew enough about nuclear physics to understand the magnitude of the serendipity that resulted in these exact physical laws. But in investigating the validity of the strong anthropic principle, in recent years physicists began asking themselves what the universe would have been like if the laws of nature were different. Today we can create computer models that tell us how the rate of the triple alpha reaction depends upon the strength of the fundamental forces of nature. Such calculations show that a change as little as 0.5 percent in the strength of the strong nuclear force, or 4 percent in the electric force, would destroy either nearly all the carbon or all oxygen in every star, and hence the possibility of life as we know it. Change those rules of our universe just a bit, and the conditions for our existence disappear!
...It turns out that it is not only the strengths of the strong nuclear force and the electromagnetic force that are made to order for our existence. Most of the fundamental constants in our theories appear fine-tuned in the sense that if they were altered only by modest amounts, the universe would be qualitatively different, and in many cases unsuitable for the development of life....'

If you were to do a similar thing to those scientists, and imagine a feature to be different, what difference would you be thinking it would make to behaviour if humans, like cups, didn't have a first person perspective?
