I'm sorry, but it doesn't address what I said about brain agency.
Is there an "electricity gene" that produces the electrical properties of the brain?
Ryan said:Finding neural correlates to the consciousness is very important and sought after in the science of consciousness, and probably the most important and sought after thing.
I hope you don't mind me snipping this single point to respond to. I think it's the key one but if you feel shortchanged, I'll return to the others later.
Here's my problem, and I think, the problem for science: There is a problem of other minds which hasn't, to my knowledge been resolved. I think this matters, conscious experience is a private experience that it is assumed that we all have. The problem is that we are all inferring that from a single case and as philosophers like Wittgenstein have pointed out, we really cannot even know that it is the same case across people as we, individually and collectively, have no criterion for judging how similar our experiences are, beyond the judgements we express in words. That's one reason why linguistic behaviourism isn't flat out ridiculous - we really don't know that others are conscious, just that we judge ourselves to be conscious, a judgement that people like Dennett assert is an indefeasible error such that judging ourselves, in language, to be conscious is all there is to consciousness, the position he holds in Consciousness Explained.
I mention all this just to really make it clear that the only example we have of putative mental lives is our own. Now, the next step concerns the methodology of science. At the heart of science are the axioms that all experiments have to be repeatable by anyone and objective. My individual conscious experience is not only not objective, it's not even intersubjectively verifiable, hell, it's barely subjective as what seems to me is indefeasible rather than factual. As for repeatable? my conscious experience isn't, nor is yours and the notion that we all have the same experience is an act of faith that doesn't bear up to even the most cursory of inspections.
I'm red green colourblind - I didn't even realise until I was seventeen and even then all I knew about is my discriminatory abilities, no one can know how much my experience varies, (See all of the 'inverted qualia' argument) just that there are some colour distinctions I can't make and some colours that I cannot distinguish well when superimposed. The point here is that no one knows I'm colourblind unless I tell them - I can use colour language better than most (I like being a psych test subject and my alma had a huge vision department - who never noticed I was colour blind while running experiments on qualia - I was a partial colour zombie and no one noticed - my heterophenomenology, aided and abetted by a degree of expertise and perfectly good hue and saturation detection meant that my few errors were outriders and not noticed. Yeah, I didn't let on, because I was blinding them as much as they were blinding me, so as to speak.
However, there's a remarkable postscript, because my color blindness isn't dependent on a lack of ability to discriminate, but in a processing issue in which my eye doesn't filter wavelength gradients properly. Last year I was given some glasses that literally cure my sort of color blindness by the simple expedient of blocking critical chunks of wavelength to allow my brain to process the overwhelming majority of the signal in a opto-neurotypical manner. As a result, I'm in the rare position to know that even if I'm still not seeing what the opto-neurotypical see I'm seeing the colour difference between twilight and midday with every berry on a holly bush (rather than being a vague shadow) picked out in psychedelic relief. Yet still, in ordinary communication you wouldn't notice the difference (and again, I repeat, that's merely discrimination, that is clearly different. No one can tell if my mental experience is the same, merely that I will use the word 'scarlet' under certain conditions, I, as Wittgenstein pointed out, learned the grammar of Scarlet, not the phenomenal and entirely personal reality. (notice how much metaphorical language I needed just to communicate the possibility of such a difference.
So consciousness isn't objective, it isn't reproducible and as for falsification and the null hypothesis, how exactly would you put forward a falsifiable account of your own, let alone another's private experience? Whenever someone tells me they are looking for correlation or more between the mental and the physical as an empirical project then all I think they need to have a think about the scope, limits and methodologies of science. If they want to say it's a metaphysical or philosophical project then I want to hear about the project in detail - it's easy to be right, you only have to be sufficiently vague, or anecdotal...
There's a faint hope we might be able to correlate the neural correlates of nociception and discrimination in as much as they are not mental events, but the raw feels of consciousness - science has no way of proving they exist, let alone correlating physical events and mental events. That's phenomenology, when it gets to intentions, you have a very different and even more perplexing problem, But that's enough about this, I have a very silly Christian to school on motor mechanics and evolution yet! (and it's bed time, my best mate is over from Magyaristan and I have to set up a bass guitar for him before I go to bed).
Careful not to get infatuated with older "teachings" like from Wittgenstein. Science as you know moves relatively fast and philosophy even makes progress every once in a while.
That said, I will respect everything from the past until "better" logic is applied.
If you are interested, you can critique a specific method from the NYU report I linked, here again http://www.nyu.edu/gsas/dept/philo/faculty/block/papers/final_revised_proof.pdf . It applies a relatively new "method" called "signal detection theory".
Or you can critique the author's justification here (NCC = Neural Correlates of Consciousness),
"Can the phenomenal NCC be studied empirically?
Doubts about whether phenomenal consciousness
(and hence its neural basis, the Phenomenal NCC) can
be studied empirically are common (see also Box 2), and
often based on the idea that ultimately, introspective
reports, that is, reports about one’s conscious experience,
are the fundamental epistemological basis of theories of
consciousness, the ‘gold standard’. [7,41,42]. Reports are
not supposed to be infallible, but any discounting of
reports as reporting too much or too little, will supposedly
have to be based solely on other reports. Reports inevitably
reflect the Access NCC, not just the Phenomenal NCC:
when people tell you about their conscious states, you only
hear about the ones that have won the winner-take-all
competition. Hence we can only study ‘access to consciousness’
[7], that is, access to experiential content, not experiential
content itself. I do not agree with this methodological
view for several reasons.
First, observed electrons can provide evidence about
electrons that cannot in principle be observed, for
example electrons that are too distant in space and time
(e.g. outside our light cone) to be observed. Why should we
suppose matters are any different for consciousness?
Second, there is no gold standard of evidence, here or in
any area of science. ... "
Something to work with.

I don't see why. I'm currently basing it on methodological problems, I can also go on to base it on metaphysical issues, but we haven't got to that point yet.will supposedly have to be based solely on other reports.

You completely miss the point.
There are genes that create structures, cells, that can create electricity thus allowing a brain to have electrical properties.
It would be the same for quantum properties.
You would have genes that create structures that somehow utilize quantum properties.
You would not have genes that create quantum properties.
What you fail to add is the most important part....the blogger is talking about a paper by neuroscientist Peter Clarke with quotes and references. The blogger is not important. The blogger is irrelevant. The necessary information is provided in reference to the neuroscientist and his paper;
Here is the paper from the link in the blog page, the blog page, if you like, being merely a conduit to the article;
Neuroscience, quantum indeterminism and the Cartesian soul.
Clarke PG1.
Abstract
Quantum indeterminism is frequently invoked as a solution to the problem of how a disembodied soul might interact with the brain (as Descartes proposed), and is sometimes invoked in theories of libertarian free will even when they do not involve dualistic assumptions. Taking as example the Eccles-Beck model of interaction between self (or soul) and brain at the level of synaptic exocytosis, I here evaluate the plausibility of these approaches. I conclude that Heisenbergian uncertainty is too small to affect synaptic function, and that amplification by chaos or by other means does not provide a solution to this problem. Furthermore, even if Heisenbergian effects did modify brain functioning, the changes would be swamped by those due to thermal noise. Cells and neural circuits have powerful noise-resistance mechanisms, that are adequate protection against thermal noise and must therefore be more than sufficient to buffer against Heisenbergian effects. Other forms of quantum indeterminism must be considered, because these can be much greater than Heisenbergian uncertainty, but these have not so far been shown to play a role in the brain.
I see that this was written in 2013 and it mentions, "To date, there is no evidence that such quantum processes are involved in neuron-to-neuron communication or brain function."
But in 2014 evidence was found by Hameroff and Penrose and found and confirmed later again by a university in Japan in 2016.
And it was also written after Fisher's 2015 research article that suggests the theoretical possibility of quantum coherence using entangled Posener molecules.
No it wasn't. If you consider the problem of physics of scale you'd realize that the macro brain does not work according to quantum principles, wave collapse, scale, etc. The brain is a macro scale structure where the role neurons, support cells and connections, signals between cells, etc, determines function and output
As I've pointed out numerous times, all brains have the same underlying quantum substructure, cat brains, dog brains, mouse brains, horse brains, human brains and so on....all with their underlying quantum substructure, yet all producing sets of behaviour not according to their quantum substructures but their macro scale architecture, their size and wiring and the information they acquire through memory and learning, each according to species and range between individuals, some smarter, some not.
That is where quantum consciousness fails.
I'm sorry, but it doesn't address what I said about brain agency.
I don't much like Ned Block's terminology, but it will do as setting up the target. Obviously I say no.Can the phenomenal NCC be studied empirically?
and

consciousness, the ‘gold standard’. [7,41,42].
This is misleading, saying the gold standard implies that some other standards are available. They are not. The only way we can get at our experience of our inner mental life is behaviour. That's it. I also note that the phrase 'the fundamental epistemological basis of theories' is a very odd clause indeed. Ontological, sure, epistemological, less so.
Reports are not supposed to be infallible,
No, but they are indefeasible, ...
non repeatable ...
and entirely subjective.
Again, this is just misleading, that's just not the problem for our verbal reports of subjective mental experiences. I've explained the problem clearly twice now: for science they are the worst sort of indefeasibl+e anecdote.but any discounting of reports as reporting too much or too little,
Reports inevitably reflect the Access NCC, not just the Phenomenal NCC:
There are two problems here. First no one has ever reported their NCC of anything.
Rorty has a go with his 'Antipodeans' paper, but he's being sarcastic throughout. Just think what a neural correlate is, it's a brain state and no one is reporting brain states, they are reporting experiences (Phenomenal) and words (access). The idea that they report brain states seems fanciful even for a mature science of the mind, let alone the current situation. Block is just being unforgivably untidy with his language. He's a philosopher and he really should know better.
And the second is a point which will trip the unwary. Access and phenomenal consciousness are Ned Block's very own terms and his very own distinction. It's a good distinction and one that I am very happy with, In fact , the first time I met him, at Turing 90 if I remember correctly, I was introduced to him as someone who held a similar position on the bicameral nature of consciousness.
Thanks for this critique. Although you know that I must critique your critique and you will probably do the same. I will skip what I don't feel strongly against.
Before I start, I just want to explain that this is more of a "soft" science like sociology (which many argue isn't a science either). But this is a science; we just have to accept more controversial premises than the more exact sciences use.
I think you are interpreting his phrase the wrong way, from Oxford Dictionary, "Epistemological: Relating to the theory of knowledge, especially with regard to its methods, validity, and scope, and the distinction between justified belief and opinion."
Ryan said:Reports are not supposed to be infallible,
Sub said:No, but they are indefeasible, ...
so are scientific observations used for research
Sub said:non repeatable ...
Of course they are repeatable and are repeated.
Sub said:and entirely subjective.
Ryan said:Then what scientists understand science, observations, research, etc. to be is also subjective. We must assume certain premises.
Sub said:Again, this is just misleading, that's just not the problem for our verbal reports of subjective mental experiences. I've explained the problem clearly twice now: for science they are the worst sort of indefeasibl+e anecdote.but any discounting of reports as reporting too much or too little,
Again, I don't see indefeasibility as an issue for reasons already given.
Ryan said:Reports inevitably reflect the Access NCC, not just the Phenomenal NCC:
Sub said:There are two problems here. First no one has ever reported their NCC of anything.
Ryan said:To report on something is not meant to provide the thing being reported on. The report of a conscious experience is an effect from the conscious experience like an electron's photon emission (as Ned might say) is an effect reported by the photon. Except it is not matter being transmitted through space, it is the intentionality of the consciousness being transmitted.
Sub said:Rorty has a go with his 'Antipodeans' paper, but he's being sarcastic throughout.

I'm not sure this answer can be a response to what is quoted above it? If it is then it's begging the question or circular, because if you are reporting your NCC then your NCC are correlating with our NCC and that's looks like a circular denial of the mental as all you would have ios the neural correlates of the neural correlates. I'd look at what you were responding to again, because it's an odd response.I disagree. It seems sufficient.
I gotta go to bed. I will try to finish tomorrow.

One word 'emergence'.

That is one word.
But the ability of matter to have quantum properties is not something that emerges. It is inherent to all matter.
Of course all biological entities and all their structures have "emerged".
