They exist as useful abstractions, but not as physical objects (which is what we practically deal with when we talk about computers).

Indeed, I believe mind is all there is, so necessarily computers are an aspect of mind and are even conscious in a sense already.

OK. We have a problem of level here. On some level, computers can emulate everything atoms can do computationally, I'll admit that. But that's simply the wrong level, since it is not about what something can do in the sense of transforming input/output. It is about what something IS (or is like). A boulder that falls on your foot may not be computationally more powerful than a computer, but it can do something important that a computer running a simulation of a boulder dropping on your foot can't - to make your foot hurt. Even if you assume we could use a boulder in a simulation with ourselves plugged into the simulation to create pain (I agree), it still doesn't do the same, namely creating the pain when dropping on your physical foot. See, the accuracy of the simulation does not help in bridging the levels.

Nope, since for the computer no experimental ways exists if we haven't determined a program first.

Yes, but how to determine that with a computer? If you program it to embrace bad axioms that lead to bad theories and don't have a lot of use he will still carry out your instructions. So the computer by itself will not notice whether it does something useful (except if you programmed it to, in which case you get the same problem with the creation of the program). Jason Resch-2 wrote: > > If the computer program had a concept for desiring novelty/surprises, it > would surely find some axiomatic systems more interesting than others. Sure. But he could be programmed to not to have such a concept, and there is no way of determining whether to use it or not if we haven't already programmed an algorithm for that (which again had the same problem). In effect you get an infinite regress: How determine which program to use? ->use a program to determine it But which? ->use a program to determine it But which? ->use a program to determine it ....

"How" may be the wrong question, since it would seem to impy that there is a algorithm that we use for that.

Idealism (which really isn't a theory of consciousness, more a stance). It is better than computationalism because it explains why we don't subjectively perceive ourselves as computer or doing computations (we aren't), and it explain where computations come from in the first place (from subjective meaningfulness) and it explains why there is any experience at all (it is irreducibly existent) and it spiritually meaningful (all there is the infinite profoundity of experiencing that isn't constrained by objective pre-defined things). Your argument against idealism isn't valid, since idealism explain why we observe a physical universe that follows certain laws (approximatly): Because order (that can be described using laws) and matter are subjectively meaningful. Jason Resch-2 wrote: > > Do you, like Craig, believe that certain materials have to be used in the > construction of a brain to realize certain mental states? I think the question is invalid. A brain doesn't realize mental states. It appears in our mind (and has some correlation to our mind). Experience can't be attributed to any entity or thing or activity. Just on a relative level they can be, but then we are talking about "mental states" and not really the experience itself. On this level, we can also attribute mental states to computers (we already do).

So you are actually agreeing with me? - Since this is exactly the point I am trying to make. Digital models exist on a different level than what they represent, and it doesn't matter how good/accurate they are because that doesn't bridge the gap between model and reality.

If we let a computer compute and don't look at what it does, than as far we can see, it doesn't generate anything.

I can't actually find something that produces it. I can only imagine that. As far as I am concerned, the brain just manifests and represents subjective processes on a objective level inside a skull, they aren't made there (no evidence for that or any reason to believe it is so, or is even meaningful). Yes, the computer can do that as well (though on a different level, if only because its representation is different).

Yet they have meaning in the context of your brain. No, the squirting has measurable objective qualities like energy (a symbol doesn't have that becaues it isn't a unique physical entity).

I am a bit sorry for you if that is the most elemental form of meaning for you. Often closing your eyes and stopping comparing and symbolizing can be much more meaningful and fullfilling.

I mean it is literally entangled with the rest of infinite existence, not just our universe. Really even according to the multiverse theory it is. There is no absolute decoherence in it and there are infinititely many universes.

Well, OK, it doesn't really matter (though I don't buy into many-worlds much more than I buy into single world). The thing is that a perfect simulation of entanglement still wouldn't be actual entaglement (since it requires there to be no gap of level - a classical computer simulating entaglement is not actually entangled with its surroundings). benjayk -- View this message in context: http://old.nabble.com/Simple-proof-that-our-intelligence-transcends-that-of-computers-tp34330236p34343299.html Sent from the Everything List mailing list archive at Nabble.com. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
