If we were all incapable of communication, suspended brains linked to bodies totally comatose for example, we might also wonder how there can be 'anything it is like' to be said brains with comatose bodies, after all, we'd only see neurons firing. It's the fact that communication exists, that we can act that gives us first person reports that there are things going on in other people that go on in ourselves, and that these things we've categorised, partly, as 'being these things'. I am interested in the whole question of being, and its metaphysical status, at the moment I'm inclined to think its just the brains way of understanding its surroundings and its own state changes. It being awesomely complex, it would come as no surprise that said state changes when the brain is working holistically generate the self from that, the self being a concept the brain uses to continue processing its environment in a way beneficial to its survival. |

Let's get to the point. What do you qualia supporters argue for, exactly? I mean, how do you see qualia, and its implications about reality? As some kind of spiritual dualism, or what? What do you think is going on here? I'm curious how you think reality is. Do you think we are disembodied souls linked to physical bodies, or what?
For some reason, this conversation is getting me to think of Zen Buddhism. Now we are asking what is the "I" that is having the experiences... The Zen Master would say, there is no "I" and it is but an illusion. If you peel the onion, eventually you might think you would get to the essential thing that is at the core of the onion, that gives it its "onion-ness." But the Zen Master would say, no, you only end up with nothing, but a pile of discarded layers of onion. |

The difficult issue is how and why we have sense data at all. The senses cannot be explained, even in principle, by any known physical laws. Nor do materialists have any explanation for why we have these senses. In a materialist model, all of our behaviors can be accounted for merely by our having the necessary information. Why does this information take the form of qualia? Quote:
The conscious subjective self consists, basically, of qualia plus memory. Neither of these are physical. I don't want to get into possible unconscious levels of the self. Quote:
In other words, how do we know that there aren't mentallings without physical processes? (And how would ever find them if you define mentallings as physical processes in the first place?) Quote:

Now physical processes become mental processes as well. It is a complete change in our understanding of matter. If certain physical processes in the brain are consciousness, then is it not also theoretical possible that certain physical processes in the sun are also consciousness? We cannot ask the sun if it is conscious, but that is hardly proof that it is not. On the contrary, we have to include that as possibility within the system you have proposed. Materialists don't want to have to do that. That is why the search for a reductive explanation of consciousness in material terms is so important to them. If you have a reductive explanation of consciousness you would be able to say the sun is or is not conscious. Quote:

I don't know much about animism but I don't think it is dualistic. Certainly dualism is not the basis of Western religion. In fact, it is more closely connected to secularism. True, Descartes included an argument for god in his meditations, but Descartes set himself up as the final judge on statements of truth. He would accept nothing that wasn't a clear and distinct idea in his own mind or that he could not establish through his own reason from those clear and distinct ideas. His position was very modern in this respect and a complete break with medieval thought. But here is the problem. A materialist vocabulary presupposes that materialism is true. But a proof that assumes what it sets out to prove is no proof at all. So a materialism cannot be proven to be true using a materialist vocabulary. All that a materialist vocabulary can do is smuggle in mental concepts using materialist terms. This obsures the mental component and that is why I claim that such an approach in obscurantist. That is precisely what the identity theory does. Since a reductive explanation of consciousness cannot be produced, identity theorists have tried to substitute a materialist vocabulary. But that doesn't change the meaning of the term. A first person report is still a subjective report. And a subjective report is still a mental report. |

I have no idea what the future holds. But when in comes to a materialist explanation of mind, every materialist I encounter suddenly becomes a psychic. The chances are just as good that future scientific discoveries will lead us farther away from such a solution as that they will lead us closer. Quote:

I have already dealt with the point of obscurantism in my previous post. I don't think I need to add anything here. Quote:
So this isn't just about philosophy of mind or just about neuro-science. It's about an entire world view. And it's about academic authority, tenure, selling books, defense contracts, and a whole lot of other things both noble and mundane. |

To anyone interested.
I'm having computer problems so I may be off the net for a few days. This has been an interesting discussion, but it may be nearly played out by now anyway. Thank you all for your participation. Boneyard Bill |

I have no problem with the term mind/matter, because I see no principled distinction between mind and matter. Mind is organised matter. The delusion that mind is someething special is human hubris. Quote:

"why does it take the form of qualia" has been explained on numerous occassions now; that is the brains subjective experience of processing inputs. Computers would have exactly the same experince of variables being shunted around their processing space too - except not, for design reasons (i.e. computers are not evolved and are not real time).

Remember that obscure investigations are not the only variety - as mentioned before, we can saw peoples heads open and compare the observed responses with the subjective experience. We can model transfere of energy via cat scans and see differential brain activity. The claim that we cannot correlate physical process with subjective experiencenis false. Quote:

That is all. Equally, you do calculaus to catch balls without ever doing it consciusly. Your conscoiusness is only one component of the brains apparatus. Quote:

I don't think there is any basis whatsoever for claiming that qualia are non-physical, or inadequately explained by physical process. Please expand on your basis for so claiming. |

I think memory involves physical codes that are encoded and decoded by a physical system. There is a pattern linking a code to its meaning or function/purpose and the physical encoding/decoding mechanisms translate inputs into the code and translate the corresponding outputs from the code. I guess I think memory is a functional property of certain physical systems - like how rotation can be a property of certain physical systems... Quote:

That stream of information that is processed and analysed by the "central executive" area (which may be in fact smeared across the brain - not localized) is the mental report. People ask why the mental report exists, so materialists like myself are trying to come up with an explanation... to do that involves referring to the original question (the existence of mental reports). |

I take it you're not equating the senses with physical systems. Quote:

But what I still want to know is how drinking alcohol can impair your thought process. Is it because thinking is done by the brain, although some other stuff is still done immaterially? Or is it because thinking is done by an immaterial mind, but there is a fundamental law which states that if alcohol affects your brain, that your mind should be affected in a specific way? Is there really a fudamental natural law to do with alcohol, or is there some more general law of which this is an application? |
