This I don't get. Humans have a long history of making stuff that widens what we can sense. We may not be able to sense a magnetic field but we can build a compass.
[...] Since the brain can process information about its own processing, basically, that processing can then feedback and affect processing in other ways, in other areas, and so on. So that is where the causal efficacy of consciousness comes from.
[...] I think that the phenomenon of consciousness isn't that highly localizable to one part of the brain, but that it's a distributed function that depends on the total overall patterns of activity produced in the brain.
I also think there is a powerful interactive component to it as well, based on the social nature of our species, and the effect that's had on our evolutionary history. (Social forces can place selective evolutionary pressures on us just as well as purely mechanical and consequential environmental factors.) I think an essential component of consciousness is that it takes place between individuals in a social context. Of course, this is essentially an unanswerable question, because we have no way of knowing if someone who would never have any social experiences, any language learning and so on, would possess consciousness.
But, in sum, that's my take on it. Consciousness is a product of both the complexity of the brain causing the development of highly recursive feedback processing mechanisms (70% of all neurons in the brain talk to other neurons in the brain, and only about 30% actually send signals to or receive them from the body), and that this process has also been shaped by our social nature and the effect that social nature has had on our evolutionary history. In short, we've selected ourselves to have consciousness to facilitate social cooperation and productivity, as it also increases our survival as a species.
[...] Because of this, I don't think we'll ever be able to scientifically quantify consciousness or its contents and qualitative experiences. The best we'll be able to do is produce a very high degree of correlation between brain function and what looks like conscious and intentional behavior, which we've already done a pretty good job with. Consciousness, because of its very nature, being subjective, transitory, and ephemeral, means we'll never be able to have a truly quantitative and scientific theory of consciousness.
[...]Earlier attempts to compare the mind to technology were a great deal further off than comparing it to a computer. They are both collections of electronic connections. I'm not certain with current computer tech we'll ever be able to emulate human brains. The limitations of binary alone pose a problem. My understanding is that neurons aren't 'on' or 'off', but more offer various levels of resistance. You could convert that roughly to multiple bits, for instance saying a byte might represent a single synaptic connection. But that leaves you getting not quite what the brain does. I understand some people can hear the difference between the digitized version of music on a CD and from an analogue LP, as an example of that difference. But all of this sort of comes down to 'close enough', where mathematicians can argue that .999999999=1.
The failing of computers in emulating human thinking is, I think, two-fold. First, they don't have the ability to perceive the world the way we do, and second, they do not have the physiological drives that we do. The word 'orange' is just a collection of symbols to a computer. To a human, it's a collection of symbols, that gets you a connection to an entire database of sensory input. It connects to visuals in color, dimpling, and a long line of oranges we've seen in our lives. It connects to our memories of smell, taste, texture, memories of a spray of mist from the skin of the orange squirting in our eyes, and the joy of eating them. For a computer, the word has a definition. For a human, the word is just a gateway into our knowledge of the item as experienced. As omnivores, oranges give us nutrition, and vitamins; things we as organic life crave. We WANT them. That want, powered by biological needs, is something a computer does not know, and honestly, I don't think could ever be taught.
[...] If the human mind is a massively powerful computer used to take sensory input and produce decisions based (in theory) on keeping the organism alive and to motivate it to procreate, then getting a computer to 'think' kind of seems like it'd have to be forced into a situation where it was required to perform the same task. As I'd rather not have Cylon overlords, I suggest we not try.
[...]The German philosopher Immanuel Kant subsequently postulated that causality is a function of cognition. Our minds are structured in such a way that we naturally make connections between spatially and temporally contiguous events and we understand that contiguity as "causation". Evolutionary psychologist hypothesized there should be some kind of physiological function in the brain for this, and cognitive neurophysiologists have confirmed we have a set of functions in the brain where different sets of neurons working together process the temporal relationships between perceptual events and work to associate those events. So we sort of have a "causation perception" function built into the brain. It's very similar to the way that visual motion perception works actually.
The way this cashes out in the sciences in general is the use of models. In quantum physics, we can't directly observe the structure of an atom, the exclusion principle makes that true by definition. So what we do is use analogy and metaphor with things we can directly observe and experience, such as seeing the planets move across the sky so they seem to move around the Earth, and we use that observation to structure our understanding of the atom. Thus we get what is commonly called the "solar system" model of the atom. I'm glossing over a lot of specific details in the argument here, but I think you'll get the idea.
[...] Everything that falls outside our ability to sense doesn't 'exist' to us. There is a great deal of reality that we are simply ignorant of, for lack of the senses to experience it. Even when we make a machine that CAN sense it, we then have to translate that information into a form our senses can take in (usually visual or auditory).

Again there's a long history of discoveries Sure some are by observing direct effect but are the discoveries made indirectly any less valid?Kind of splitting things here (but like this thread is any way on a track )but is my "sensing" of a magnetic field via viewing the needle on a compass or the pull on a lode stone any less valid than if I had iron deposits in my skull that let me know the same thing without the compass If I built a hat with a bunch of hall effect sensors linked to solenoids pressing on my head and wandered around looking silly like that for a few weeks until I no longer really registered the individual pushes as touches but now always knew which way I was facing would that be a more valid "sense" than looking at the compass? Oh uh, now I'm thinking about how I could build the hat I look silly enough as it is!

So what is the most recent thoughts on what's going on with Synesthesia? Some serious wires crossed there.
Also, on language, and animals use of it... and just because I find it highly amusing and moderately cute... the language of prairie dogs.It brings up a good point of the problem of cracking the language beyond a certain level, due to lack of context. This is also true for whale and dolphin speech. Having no context, it's really hard to determine what they're saying. For apes and chimps being so nearly related genetically, I think there are many other species with much more evolved language abilities. I'm not suggesting it comes near to the level of abstraction that humans are capable of, but then again, I'm not certain anyone has ever strapped a bottle-nose dolphin into something to read it's brain activity while it's chattering.
I watched a documentary the other day, 'China's Century of Humiliation'...Hulu - China's Century of Humiliation - Watch the full movie now.And at one point, it was discussing a definition in an old Chinese dictionary for the English word 'Privacy'. I don't remember it verbatum, but it was something like 'The western pride in the sadness of being alone'.
Words can facilitate thought, or limit it, but at least for me, my 'native language' in my brain is usually a flood of images. It then has to go through a filter, where I have to pick the best words to articulate what my brain wants to communicate. If other people experience this as well, I seem to be more consciously aware of it for some reason, like my linguistic translator is a lazy slob who complains when it has to do its job.
I sort of imagine words like paved paths. There are lots of places in between them, but usually there's a word to get you where you want to go. I personally have no problem 'hopping off the trail', in my thoughts. I suspect some people's 'native language' in their brain likely IS language. And I imagine some of those folks hungrily scour their own and other languages, finding new words, and opening up new avenues of thought. Harder for them to 'walk in the grass' off the trails normally provided by words.
While we're hard wired for language, and develop a new one in the absence of one provided, I'm virtually certain people don't build them in their brains the same way. Two people, speaking the same language, likely have two very different means of developing the linguistic software and database to support it. Sorry for all the IT terminology. It's just the most apt words I have. Oh, the irony.So... assuming any of that made any kind of sense...
I don't have anything of substance to contribute to the current discussion right now (nothing new there ), but I just wanted to say thank you to this community, especially Heinz, user24, Lynn and Neil, for this excellent exchange and generously sharing your perspectives and knowledge. It brought me back to college with excited late night discussions of Big Questions.

While I'm an electrical engineer by trade, one of my hobbies is theology. As an offshoot of this, I've done quite a bit of reading/research about the differing social and cultural norms both in the ancient near east, and some representative cultures today.This quote illustrates one of the more basic differences between a collectivist culture like China, and more individualist cultures like most modern, western nations.
Yeah, I've got to say this is one of the more interesting, and least-expected discussions I've seen on the web in some time.
