How the hell you "measure the consciousness"?
That's a circular argument.
Basically the only consciousness you can "measure" is your own, and then you infer that things that appear like you are also conscious. That's the logic.
But the basic problem is this: in what respect?
And nobody knows the answer.
So, your fact is no fact, and to claim it is a fact is a piece of pseudo-science.
Quantum mind is one theory, and it ought to be taken seriusly, as it makes perfect sense. If you ask me, it's the most appealing option, but this my subjective opinion.
Calling quantum theories of consciousness "supernatural" is beyond ridiculous. These models are 100% naturalist, based on, for Christ's sake, an interpretation the best verified scientific theory (QM) in whole human history!

But none of that was in there. Hameroff and Penrose may have even written the original article, I don't recall, that other sites then simply borrowed from.
I think the articles themselves even included mention of Orch OR in the headline or subtitle.
Ok. I have only read Penrose's Emperor's New Mind and the article I gave the link to and couple of its reviews. So I am no specialist. So I got you somewhat wrong. In any case they base their evidence on some findings in quantum biology concerning photo-synthesis and more directly some research on microtubulars, if I remenber correctly, which falsify the argument based on decoherence.
Personally, I used to believe the theory was an error because of the decoherence argument, but now it seems that I have to reconsider it.
I am not a Believer, and obviously the theory can be false. In any case, I respect it as a good guess.
I read their brief summary of the theory as part of a wider range of contributions in the excellent book "Explaining Consciousness: The Hard Problem" by Johnathan Shear. I don't reject Orch-OR because honestly, I just don't understand it really. And while Penrose is unquestionably a brilliant physicist, I have my doubts about Hameroff. I don't like that he seems overly enthusiastic about pushing his theory into almost cultist, unscientific territory, such as that of "quantum healing," which I don't think offers any validation to his ideas and somewhat discredits him (in my mind).

Yes, it's impossible to appraise that stuff without profound knowledge of QM and neurophysiology. I am not a physicist nor a neuro- physiologist, and all that molecular stuff in particular goes over my head, and the physical ideas I can understand only on a superficial level. My "real" knowledge is limited to the basics of QM and the philosophical ideas behind the various interpretations. So, I have no idea how valid the Penrosean interpretion is; but as he has worked with guys like Stephen Hawkins and as his model is considered respectable by mainstream physicists, it would be a folly to claim it makes no sense. I also share your doubts about Hamerhoff. Obviously he is what is called "an enthusiast". But flirting with new age can only tell that he is only a curious and open-minded person who can perfectly well distinguish hypothesis from fact. It's hard to tell. In any case, even if is a newager, his theory can still be valid. Just think W. Pauli. It's not too uncommon that excellent scientists are "enthusiasts"; actually the aggressively "naturalist" types are seldom on the top of their fields.

What are the criteria for establishing that a given physical structure is conscious? What evidence will be accepted? If you dare even to answer, I guarantee you'll define mind in terms of physical correlates, like brain waves or blood flow, and not in terms of qualia.
If one has thus to cheat on a semantic level to fit reality into his model, then the model is insufficient. And that's why physical monism fails.
"We don't yet have an answer" is not equivalent to "It's a failure".
I would accept a physical structure as conscious by its behavior, not by particulars of its structure.

And I didn't say physical monism fails because it hasn't yet explained why mind exists rather than not. I said it fails because talking about mind in a physical monist model requires defining mind as what it is not: chemistry, blood flow, etc. That's not what mind is. Mind is the subjective experience of qualia. The other things are correlates that we have chosen to look for, because we have no good way to determine what structures are/aren't experiencing qualia.
Quote:I would accept a physical structure as conscious by its behavior, not by particulars of its structure.
That's right. You have to, because nobody can see or interact directly with a mind, and you don't want to do science about fairies, IPUs, mind, or other intangible things that nobody can even see. The problem is that as mental beings we do in fact know that minds exist. It's not the mind's fault that a particular world view cannot readily adapt to its reality and obvious existence. But you have a problem: some things may behave in ways that make them seem human (or will, very soon, with AI); also, some beings experience which exhibit no noticeable behaviors at all-- some coma patients, for example.
Quote:Physical monism is the only theory with any supporting evidence. Nothing else has any at all.
That sounds great until you realize that you are talking about a standard of evidence which requires everything being defined in terms that fit into the theory you are supposedly using the evidence to investigate. That's exactly the definition of "begging the question."
Again, the fact that some things are not well-suited to be obects of scientific study is not their failure. The instistence that they be redefined to "fit in," however, is a failure-- to accept reality. There's irony there, because science is supposed to be a tool for objective inquiry-- not the imposition of philsophical beliefs on direct observgation.

How does QM solve the binding problem? Again, nobody can use QM to fully explain an electron pair but some want to jump straight to solving the problem of consciousness.
I have no problem with the implications of dualism. I have a problem with the lack of evidence for dualism and the fact that all dualist explanations make the system more complicated. We don't need an out of body mind to explain what we observe. Could there be? Who knows at this point, but evidence suggests no and I don't have to take it seriously until evidence is produced to suggest I should. A few loud adherents is not evidence.

Your going to have to explain why this is relevant. We only observe consciousness in a narrow description of existents. Assuming that non-living existents could have consciousness because we can't develop a test for something that is outside our experience is getting close to "what if D-O-G really spelled cat". I think we should figure out how the consciousness we can observe works before trying to determine what tickles a rock.

It would have been easier to type "I have no evidence". You are free to believe in ghosts if you wish, but until you provide a compelling reason for the rest of us to do so we really don't have to take any of this seriously. You can't just wave your hands and eliminate the need for evidence by stating that we are imposing philosophy on observation. Where's the evidence?

Give me an example of a non-physical structure which actually experiences qualia, rather than just seeming to. In fact, you can't demonstrate a non-physical structure that just seems to. Just one example that supports my position is that my grandfather's experience of the taste of meatloaf disappeared when his brain died, unless you are going to make the argument that his experience is disembodied and floating around in the proverbial ether.

Maybe you should define what evidence means to you. What nature of evidence would you consider relevant to the OP, or to the past few posts?

I haven't made any statements of faith, so you are wrong to use the word "again."
Science can mean a lot of things, but I assume we are all in this thread talking about science as it is practiced now: physical observation, hypothesis, and experimentation or other methods of confirming the hypothesis. And-- most importantly-- the ability for others to independently reproduce the observation and confirmation.
Some things are not observable by others. For example, my qualia are real and easily identified-- by me. You, however, cannot ever have access to my "what it's like to drink cocoa" sensations. At best, you can correlate someone's verbal descriptions with physical markers, like blood flow or brain wave measurements. Qualia themselves are therefore outside the sphere of science, because they cannot be observed, directly interacted with, or even confirmed to exist. Correlations between reported qualia and the brain, on the other hand, are within the sphere of science, because verbal descriptions are sharable, as are brain scans. The problem is that people are not careful in distinguishing between the two.

How do you know your grandfather wasn't a philosophical zombie? You know what words came out of his mouth, the look in his eyes, the way his limbs moved; you might have had access to fMRI or other brain scans. His qualia, if he actually had any, are for you only a matter of philosophical assumption.
Now, let's consider the OP proposition. How would you know whether an atom, or a star, or the galaxy has some kind of awareness-- its own kind of qualia? You can't-- because you never had access to qualia in the first place. An atom won't produce words about meatloaf or have shaky hands, or show any of the physical markers that make you feel justified in making your philosophical assumption about people's minds.
