Taffy,
In order for a machine to exhibit human "consciousness", it would have to be constructed using reference from homology, not from analogy. The homology of human consciousness remains a topic of wild speculation. Ierrellus PAX |

Humans are almost consciously unaware of their low level processors. This in fact does not mean that the human is unconsciously not-blind to its parts.
Again you fellas (no women) are being selective in your connotations. You are all basing your replies on the assumption that the only things that perform acts of consciousness are conscious. You ignore completely the supporting staff of consciousness. Again I will quote from nature. We are blind to how the eyes see, we are not conscious of the mechanisms of sight, we are not conscious of the means of sight. However this does not imply that the mechanism of sight is blind to what it is doing, or what it is seeing, BUT, it can report conditions of itself, conditions of its network, conditions of its topology... Suddenly your eyes hurt, start to fail, but, you were never conscious of the cause, how can this be? Sammi Na Boodie (I am b ack) |

Tron,

Here, let me make it plain, the brain and body are part and parcel of an organism. Now, if you create, somehow, a human style brain and put it in a human body, you may have created human intelligence. If you create a machine of electronic components, that becomes, one way or another, self aware, you may have created some type of machine intelligence. Will the machine have feeligs comparable to the human? I really don't know why I bother. Do you have even a incling about the structure and function of the autonomic nervouse system? Will your machine breath? Will it know the feeling of asphixiation? The unconscious, so let's see, you'll provide the capacity for emotional trauma and let your machine develope phobias. This is part a survival mechanism that predates brains of any sort. Do you think it depends mathematical algorithims? Talk about a laugh. Why not go and actually think about your position before posting nonsesne. Why is it not clear to you that human style consciousness requires a human style body?(Just like bat style consciousness requires a bat style body, no?)

Sammi,

I would add that the sensations involved are specific to a biological organism. If they can be reproduced, or even approximated, by a different type of "machine", well that would be a pretty difficult proposition to support. SB |

John Searle says some things relevant to your claim about computation. In his book The Rediscovery of the Mind, Searle has a discussion of computation in which he points out how the concept implies 'multiple realizability'. He says "To find out if an object is really a digital computer, it turns out that we do not actually have to look for 0's and 1's, etc.; rather we just have to look for something that we could treat as or count as or that could be used to function as 0's or 1's. Furthermore, to make the matter more puzzling, it turns out that this machine could be made out of just about anything." Searle thinks that multiple realizability implies universal realizability. He says: Quote:

You have not justified this assumption, you have merely put forward as a matter of fact that there is something (what it is you don't say) about biology that permits consciousness, something that other sorts of organization cannot emulate. Hey Taffy, thanks for bringing up this point!: Quote:
When he asserts that we could find a pattern of molecules structurally isomorphic to a computer program in a wall, I cannot help but wonder how the wall manages recursive feedback and functional quirks of a computer program. How exactly would we go about finding this isomorphism? Searl doesn't clarify what he means in the quote at question. The devil, in this case, is most certainly in the details. Let us imagine we are something very near gods. We pick out a few trillion air molecules to emulate a brain. Since their movement is quite chaotic, we need to invoke our super-intelligence and come up with a fantastically complicated procedure to translate the movement of these molecules into sensible, coherent cognition. Now here is the devil: the procedure by which we interpret the air molecules as a brain will itself be far, more complex than the system of air (or the wall), indeed, FAR more complex than the brain itself! Now I wonder, at this point, how much of this computation is really a function of our vastly convoluted interpretive mechanism, and how much of it is the chaotic movement of air molecules, or the slow oscillation of our wall? How much of Michelangelo David is marble, how much of it is the work of Michelangelo? ------ Searl's conception of computation being relative to an observer is not without merit. We can treat natural events as decision algorithms, for example flipping a coin. However, he places undue stress upon the observer being conscious, a well evolved observer. Functional proccessing occurred for billions of years in functional nervous or chamical systems in small animals and cells before we observers ever came onto the scene. Regards, Synaesthesia |

Can other types of matter acheive consciousness; I guess so, but no one has seen it yet. Will it's nature be different than biological consciousness, think the answer has to be yes. I guess that I could go on to say that the sensations of biological creaturs will differ from the sensations experienced by non biological creatures. Further, I would say that whatever "feelings" or sensations that may be experienced by non-biological creatures, would be unrecognisable, as such, to biological creatures. Why? Because feelings are inseperable from changes in physiological states.

snatchbalance, permit me to quote myself:

Now, what if we start in on your brain? If we gradually replace each neuron in your brain with machines that simply mimic the operation of organic neurons, down to their responses and production of neurotransmitters, will you still be human? Yes. If it's done well enough, you won't even notice. If we then do away with hormones and neurotransmitters, with each artificial neuron transmitting to a computer which then simulates their action and feeds the result to the other artificial neurons will you still be human? Yes. Again, if it's done well enough, you won't even notice. Now, if we gradually replace each artifical neuron with a computer simulation, will you still be human? Yes. Yes again, if it's done well enough, you won't even notice. So, what do we get if we put these two scenarios together? We get you living entirely within a machine, and you didn't even notice. Exactly how are the brain and the body part and parcel of an organism now? Quote:

Taffy Lewis, I never claimed that the brain was a digital computer, which makes most of your post pointless. Everything that the brain does could be done by a digital computer, but the brain itself is not a digitical computer.
