Aww, shucks. It's mutual. I usually feel as if I'm second fiddle when we're in the same conversation.
…then you’d be one of the first ones here who’s actually agreed with the conclusions of those neuroscientists I’ve quoted.
Point one: It’s a provisional conclusion (as I’ve repeated ad nauseum).
Point two: What is consciousness? What is it that actually does arise from the brain?
Point three: There are valid reasons to believe the issue may be far more complicated than that. Not least of all being the fact that the brain is effectively the most complex object in the known universe and consciousness is all-but the greatest scientific mystery there is (for reasons that will not be explored here).
An example of what this implicates can be found with Cristof Koch who regards ‘consciousness’ as some variety of extra-corporeal generic reality.
Wikipedia said:Koch advocates for a modern variant of panpsychism, the ancient philosophical belief that some minimal form of consciousness can be found in all biological organisms, from single cells to humans, and in appropriately built machines.
Generally speaking, consciousness is regarded as a range of behavior. Another poster…well-known for his materialistic POV…vehemently insisted that something is conscious if it demonstrates conscious behavior. Thus, computers are conscious.
When pressed to present a definitive list of these so-called conscious behaviors (so we can recognize when something is, or is not, conscious) he quickly vanished. No list ever materialize, and none ever will until we can either explicitly adjudicate subjective experience (consciousness) or until we can explicitly understand how the brain generates it.
Your interpretation may be correct. First of all, it is…and can only be…an interpretation. You have a grand total of absolutely zero ways of verifying it.
Secondly…your interpretation may not be correct. Perhaps the patient is experiencing some variety of authentic event, whether it is artificially stimulated or not. We still have no way of verifying it.
One of the most hilarious hypocrisies I encounter in this whole debate is the degree to which many skeptics summarily dismiss these anecdotal reports based on the fact that anecdotal statements (self-report, personal observations, etc.) do not qualify as a legitimate form of evidence…
….yet at the very same time they are far more than legitimate enough to qualify as confirmation of a hallucinatory event (is there any other way to confirm that someone has had a hallucination other than for them to describe the thing?).
Science is not the only valid epistemology. I’m sure you’re aware of that.
The POV often taken here is that…if a phenomenon cannot be credibly adjudicated by science…then there must be some variety of limitation in the phenomena.
Nope, there is a limitation in the science.
I’ve no doubt that just about everything about an individual can be altered by brain damage in one way or another. You keep saying this as if it somehow makes all those other issues go away.
What it comes down to is the very simple question: What is a human being
Science currently does not come anywhere close to having a definitive answer.
…and the fact remains…that subjective experience has evidentiary primacy.

Even us second-stringers get the occasional moment in the limelight. Like in Star Trek, when Ensign Jenkins actually got to fire his blaster once.
And then died.
The whole premise seems to be:
We all know nothing therefore anything may be true, along with a lot of attitude.
Excellent post all around, but this bit struck me. Are you suggesting that annnnoid has (a) not read (b) not understood or (c) misrepresented something he referenced? I am shocked.--snip--
Flatly wrong. Likely based on a complete lack of understanding of what is actually being said by the Wikipedia article on Christof Koch:
Koch does not regard consciousness as an "extra-corporeal generic reality", which is a meaningless phrase. He regards it as an emergent property of certain systems, and theorizes that it is present in more systems than most would readily admit.
So it is either a straw man or a complete lack of reading ability. Either way, wrong.
--snip--
Taken literally, panpsychism is the belief that everything is “enminded.” All of it. Whether it is a brain, a tree, a rock or an electron. Everything that is physical also possesses an interior mental aspect. One is objective—accessible to everybody—and the other phenomenal—accessible only to the subject. That is the sense of the quotation by British-born Buddhist scholar Alan Watts with which I began this essay.
I will defend a narrowed, more nuanced view: namely that any complex system, as defined below, has the basic attributes of mind and has a minimal amount of consciousness in the sense that it feels like something to be that system. If the system falls apart, consciousness ceases to be; it doesn’t feel like anything to be a broken system. And the more complex the system, the larger the repertoire of conscious states it can experience.
...experience is a fundamental aspect of reality and is identical to a particular type of information—integrated information. Consciousness depends on a physical substrate but is not reducible to it. That is, my experience of seeing an aquamarine blue is inexorably linked to my brain but is different from my brain.
Any system that possesses some nonzero amount of integrated information experiences something. Let me repeat: any system that has even one bit of integrated information has a very minute conscious experience.
IIT makes two principled assumptions. First, conscious states are highly differentiated; they are informationally very rich. You can be conscious of an uncountable number of things. Think of all the frames from all the movies that you have ever seen or that have ever been filmed or that will be filmed! Each frame, each view, is a specific conscious percept.
Second, each such experience is highly integrated. You cannot force yourself
to see the world in black and white; its color is an integrated part of your view. Whatever information you are conscious of is wholly and completely presented to your mind; it cannot be subdivided. Underlying this unity of consciousness is a multitude of causal interactions among the relevant parts of your brain. If parts of the brain become fragmented and balkanized, as occurs in deep sleep or in anesthesia, consciousness fades.
To be conscious, then, you need to be a single, integrated entity with a large
repertoire of highly differentiated states. Even if the hard disk on my laptop exceeds in capacity my lifetime memories, none of its information is integrated. The family photos on my Mac are not linked to one another. The computer does not know that the boy in those pic-tures is my son as he matures from a toddler to an awkward teenager and then a graceful adult. To my computer, all information is equally meaningless, just a vast, random tapestry of 0s and 1s. Yet I derive meaning from these images because
my memories are heavily crosslinked. And the more interconnected, the more meaningful they become.
That piece goes to how consciousness arises.Integrated information makes very specific predictions about which brain circuits are involved in consciousness and which ones are peripheral players (even though they might contain many more neurons, their anatomical wiring differs). The theory has most recently been used to build a consciousness meter to assess, in a quantitative manner, the extent to which anesthetized subjects or severely brain-injured patients, such as Terri Schiavo, who died in Florida in 2005, are truly not conscious or do have some conscious experiences but are unable to signal their pain and discomfort to their loved ones [see “A Consciousness Meter,” Consciousness Redux; Scientific American Mind, March/April 2013].
Quite clearly a refutation of the idea that there is a universal consciousness.IIT addresses the problem of aggregates by postulating that only “local maxima” of integrated information exist (over elements and spatial and temporal scales): my consciousness, your consciousness, but nothing in between. That is, every person living in the U.S. is, self by self, conscious, but there is no superordinate consciousness of the U.S. population as a whole.
Ah; I thought I'd explained fairly clearly that it is - and in particular, the memories that he refers to:Nonpareil said:Forgive my slowness, but what are my memories of vivid dreams supposed to be evidence of - other than vivid dreams being memorable?
Annnnoid insists that memory is not fallible.
... It is well established that episodic memory is unreliable, including autobiographical memory. That doesn't mean you forget vivid experiences (although you may), but that, if you recall them, the content is likely to be unreliable. So it's likely that my current recall of the dream may not correspond precisely to what I dreamt, or how I would have described it the morning after. For most memories, especially dreams, it doesn't really matter.
There is also the possibility that I never had the dream at all, and have unwittingly incorporated it from other sources or confabulated it. This kind of thing has been shown to occur, but seems unlikely in this case, as I have other memories of describing it at various times, including shortly after.
Heh! me too! especially when half the time I don't understand what people are talking about here...Aww, shucks. It's mutual. I usually feel as if I'm second fiddle when we're in the same conversation.

Let’s try again: The majority here agree to varying degrees that consciousness is not separate from brain and that the evidence for such is definitive. The majority here agree to varying degrees and with somewhat varying wording that there is no definitive evidence regarding exactly how consciousness arises. If you’re interested in my personal position with a bit more precision, I defer to MuDPhuD. He is the resident expert for purposes of this thread.
Try this one simple paper. Of course, you are likely to say it doesn’t “definitively” discern anything, but that’s not your claim here.
http://wagerlab.colorado.edu/files/papers/Emot_ch_R1_opt.pdf
More importantly, it remains irrelevant to whether or not consciousness is separate from brain.
"subjective experience has evidentiary primacy" is annnoid's core position. Even the post picked out above on this page is just cover for this one thing.
He thinks that his experiences are the reality, and everything else is inadequate approaches to explaining his experience.
To me, his foundation is dissolved by the fact that two people in the same place and time can experience two different versions of the objective situation.
Does he think "reality" is in a constant unopened Schrodinger's Cat box condition? We each have a universe in our skulls?
I challenge annnoid to write a short story, or a novel, depicting the reality he believes takes precedence over the objective world we address through science. If he can work it out convincingly in a story, addressing the problems with the mentality (i.e. the integrity) of a serious sf writer, I will gain some modicum of respect for his thinking, which respect has been completely removed by reading the half-baked assertions he passes off as "arguments".
That's a serious challenge. It might illuminate his ideas' shortcomings to himself.
Take yourself seriously, annnoid. Think it through!

But that's only for the careless and incomplete reader.

Summarydodge:
Drifting slightly off-topic, I do think it stretches the boundaries of consciousness some way beyond what most people would accept, and in doing so, makes it even less easy to grasp. It's reminiscent of Pixymisa's past musing on minimalist consciousness on these forums - I'm wondering if that's more than a coincidence...It is not Panpsychism that Koch espouses; it is Integrated Panpsychism.
Can't bring yourself to admit that you've adjusted your claim?Summary:
Many of those who have been arguing the positions you (Garrette) are arguing have posted no evidence. They have constantly insisted that they have. If you want to go and find the evidence, be my guest. I am going to waste no more time on them.
Thank you, thank you. I'd also like to thank the Academy, my parents....annnnoid said:Some people have posted evidence. Congratulations.
I've never suggested you did. I honestly couldn't parse that statement in a way that made sense. That's why I called it nonsensical.annnnoid said:I have never suggested that science explains nothing or that anything is possible. I have repeated this frequently. Strange that there are those who continue to insist that this represents my position. Science has enormous explanatory power (but it is not the primary human epistemology) and I simply reference the facts as they can be examined.
Nope. Doesn't fly. It was in response to me, and the phrasing indicated you thought it led to a definition of definitive. It's a minor thing in the scheme of things, though, and I hold no one to standards of perfection.annnnoid said:The reference to ‘google it’ was probably more intended for Nonpareil since it was exactly that variety of ‘evidence’ that he would frequently present.
Okey dokey.annnnoid said:I don’t care what the rest post here. You can assume that I am only interested in the opinions of those I reply to.
You first. Are you willing now to backtrack on your claim that no technology in "any way shape or form" can determine the type of mental event that occurred?annnnoid said:Okay then. Given that paper…and however many others you are or are not aware of. What, specifically, could be determined?
Depends which issue you mean, as you continue to conflate them.annnnnoid said:The error you folks make is that you think this issue is simple, straightforward.
You misinterpret then.annnnoid said:You seem to have little appreciation for the almost incomprehensible complexity involved.
Not my first mental rodeo, son.annnoid said:Not to mention...that, in this singular case, the object of scientific inquiry is the exact same phenomenon that is conducting the inquisition (you can think about that later...eventually the implications will begin to appear).
I suggest you not mix the terms. Stick with consciousness.annnnoid said:The complexity is compounded by two massive and intractable problems.
The first is the fact that human nature (consciousness) is not understood.
Back to the car analogy. There are engines with carburetors, engines without, piston engines, Waenkel engines, gasoline engines, diesel engines, electric engines, solar engines, hybrid engines, 8 cylinder, 6 cylinder, and more.annnnoid said:What it is, what constitutes ‘normative’, the all-but infinite range of variations and nuances involved.
The sun has gone again from the sky and with it the heat. It has ever been thus, yet I cannot tell you that the heat upon which we survive is a product of the sun for I do not know its workings.annnnoid said:The second is the all-but incomprehensible complexity of the brain itself. It is not for nothing that it has been described as the most complex object in the known universe.
Which gets us exactly back to where you keep denying you are:annnnoid said:If you read that paper you cannot help but run into these two singular issues…not just in every paragraph, but in every sentence, and almost in every single word.
. Neuroimaging of Auditory Hallucinationsannnnoid said:I haven’t read the entire paper yet…and it’s clearly an example of the evolution and development of scanning capabilities. But they would still be utterly incapable of determining whether or not such an event were authentic or hallucinatory. Not even conditionally incapable…utterly incapable.
What does meaning have to do with the question of whether consciousness is separate from brain?annnnoid said:And it is the definitive part that is relevant. What you have to understand is that there are TWO phenomenon occurring here. One is the electro-bio-chemical neural activity. The other is the subjective experience. You. Koch refers to that very thing in his statements. What science is currently doing is adjudicating the phenomenology of the former… simply because it has absolutely no ability to deal with the latter with any degree of coherence or precision.
How do you measure meaning?
Human nature. Not consciousness. That conflation belongs to you. Not also the use of "likely," for which you have excoriated others' links here.annnnoid said:It is as Noam Chomsky once said: ‘ …everything ultimately gets reduced to human nature…where our knowledge is thin, and likely to remain so…’
My day will be full of weeping.annnnoid said:Regrettably, your ‘respect’ does not even begin to be worth the time it would take me to earn it.
I know Nonpareil quite well, thank you, and I knew him just as well in all his previous JREF/ISF incarnations, and I can say that I do trust him immensely.annnnoid said:I’d say the ‘careless and incomplete reader’ had better start thinking on what I said earlier. Your eagerness to expose my flaws is touching, but perhaps you’d better have a look at this link before deciding whether Nonpariel (Argent in the link) is the kind of individual you want to be trusting:
http://www.internationalskeptics.com/forums/showpost.php?p=6938370&postcount=2043
. No. Not in the slightest. It would have done (or at least close enough for our purposes here) had you left out the extra-corporeal bit. Koch is abundantly clear on that topic. Care to retract?annnnoid said:In reference to universal consciousness, panpsychism, whatever-sim.
…yet more silliness. Quite obviously, this is not a field in which any variety of scientific or semantic consensus has emerged (why does that sound familiar?). If you note the second sentence…the one you DIDN’T highlight, it quite clearly describes what I was referring to.
Yes. And it's corporeal, not extra-corporeal.annoid quoting Koch said:Any system that possesses some nonzero amount of integrated information experiences something. Let me repeat: any system that has even one bit of integrated information has a very minute conscious experience.
Not relevant to the question of consciousness as separate from brain. Do try to stay focused.annnnoid said:The frontiers of physics are currently in the process of grappling with theories that describe the universe in holographic, uni-dimensional or multi-dimensional (depending on who you talk to) terms where-in the basic elements are informational (quite literally… ‘bits’ of information).
"could very well be."? Another phrasing of the type you excoriate in others? Surely you can do better.annnnoid said:Thus…we have information processing as the very heart of reality. What Koch refers to as nonzero amounts of integrated information could very well be the fundamental conditions of everything.
Absolutely not. For the irrelevant bit about information being fundamental, it does not imply that all information is conscious.annnnoid said:…thus…everything is some variety of consciousness. EXACTLY what Koch was talking about.
Try again, sir. Reading is fundamental.annnnoid said:Quite clearly…a refutation of the refutation of the idea that there is a universal consciousness.
I agree it stretches the definition/application of consciousness, and I am insufficiently familiar with the details of the theory (and will likely always remain so as the details probably require reading of real science as opposed to really good simplification of real science) to determine to what extent I agree.Drifting slightly off-topic, I do think it stretches the boundaries of consciousness some way beyond what most people would accept, and in doing so, makes it even less easy to grasp. It's reminiscent of Pixymisa's past musing on minimalist consciousness on these forums - I'm wondering if that's more than a coincidence...
If consciousness is proportional to a measure of the integration of information, it raises questions of precisely what qualifies as integrated information (i.e. structure & function outside of the information-theoretic calculations of Φ they propose), and what is minimal integrated information, i.e. where does minimal IIT consciousness begin? For example, is it 'like something' to be a smartphone? (I don't know the Φ for a typical smartphone, but it is a network of causally interacting parts and rich in information).
As I currently see it, IIT is a good framework, but II is a necessary but not sufficient condition for consciousness (i.e. conscious awareness). I think information needs to be integrated in particular kinds of ways to have/produce consciousness. But I guess it depends how you define consciousness and integrated information; there's the problem of circular definition - if consciousness is integrated information, then it's not II if it's not conscious, and it's not conscious if it's not II... ?
