Hello Dr. Sizemore, "Glen M. Sizemore" < in message news:<[EMAIL PROTECTED]>... > GS: Teleological? There is nothing teleological about explaining some > phenomenon by pointing to events in the past. Evolution does exactly that. > It would be teleological if I explained some phenomenon by reference to the > future as is done when cognitive "science" and philosophy talks about > expectations, purposes, etc. Eray: I think I've used the wrong term, although I had the right idea on my mind. What I meant was "cause and effect explanation". You are right, teleology is concerned with ends. Although it still makes sense if you think of the current behavior as the end, and the behavior as the designing process, the end doesn't have to be in the future with respect to our present being. GS: Can't say that I follow this, Eray. Eray: The philosophical problem that I see should be reformulated as follows: the behavior of an organism is caused by its mind first and foremost. It doesn't matter whether this has been created by God or learnt. Everything has causes, and you can take that chain of causes as far as you would like to; what has caused a particular change in mind (environment or something else) is not the direct cause of behavior at an instant itself. GS: Yes......of course I am familiar with this position. It is simply Newtonian Determinism (despite the gratuitous mentalism). You want to claim that your vision of science is correct, and the things that I say are not scientific because I do not point to causes that are temporally contiguous with their effects. The problem with this view is that we cannot currently do much with it. This might be too pragmatic for you, so let's examine it from another point of view. The immediate cause of behavior - at least that portion of behavior that is constituted of movement is produced when certain biochemicals occupy post-synaptic receptors at neuromuscular junctions. Would you have it that what has caused this secretion is not the cause of the behavior? BTW, where does the "change in mind" occur in this chain? What would we measure (other than behavior) to know that the alleged "mind" had changed? Eray: There is a trivial thought experiment that demonstrates this: a child can pop out of nowhere, with no causation at all and start behaving. Here, there is a child that just appeared in a flash, and he can read all right. How can you explain the origin of child's behavior? I think you will not be able to explain it, the only course now is to denythat such a thing can happen. GS: This misses the point. The point has nothing to do with whether or not we can conceptualize a person or animal as a machine, the point is that we cannot look inside the machine and see the selective forces that produced its characteristics in cases where the thing did not "simply pop into existence." Even if your thought experiment could be real, it doesn't change the fact that real people do what they do because they have been exposed to contingencies of reinforcement. This POV will, in fact, become obsolete if we are able to give people extensive behavioral repertoires, without arranging contingencies, simply by directly messing with nervous tissue. Let me know when this happens, OK, Eray? Because right now it isn't science at all - it is science fiction. Eray: That is why it seems behaviorists are attributing behavior itself an assumed metaphysical role. I can see no scientific or philosophical reason why we should take that as the principal substance of our mental processing because as the thought experiment shows, denying the possibility of the thought experiment is the sole resolution for the radical behaviorist and in doing so you will have made behavior some kind of forbidding God. (However, it is very fruitful to accept the environment as the fuel of psychology, without a complex environment there is a low limit to the complexity of the individual) I can imagine that one could say "but this isn't impossible in the physical world, so it must be an invalid thought experiment". However, you should take into account the fact that if we make an AI that does not learn, but is completely designed by engineers and knows how to read and write, a behavioral explanation will get unnecessarily complex. In fact, I think it will get so complex that it will lose its persuasive power which may hold in some cases. It will be especially hard to talk of reinforcement learning in a cognitive agent that cannot learn. GS: I have already dealt with most of this as irrelevant to the issue, because the issue is how contingencies of reinforcement alter behavior and how this effect is mediated by the nervous system. In any event, though, I doubt that we will ever produce AI that can do a lot of things without making it "trainable" but, again, that isn't the issue. Eray: Let's ask the readers if they "can explain a child's reading by pointing to the educational practices that produced it." GS: Are you saying that people do not attribute a child's ability to read to its exposure to - at least in part - a history of educational practices? Eray: Will they find it doable? GS: I must be missing your point because it seems silly to argue about whether or not a child reads because - at least in part - of exposure to certain educational practices. Eray: I also think this kind of explanation explicitly disallows one from explaining creativity or consciousness which are not fictious entities, even if they are misunderstood to a large extent. GS: Well, you would have to make an argument for me to respond. I can, however, respond that I see no evidence that "creativity" and "consciousness" are things. Certainly not in the sense that one can point to evidence that, say, atoms are things. These are terms that appear to be used when certain sorts of behavior is observed. Later, because of indoctrination into mentalism, we simply claim that they are hypothetical things. But nothing changes the fact that they - from a scientific standpoint - are simply inferences* from behavior, that have no other characteristics, that are used to explain the behavior from which they are inferred. If you would tell me how to measure these things independently of behavior than we will talk about their being "entities." And, no, you don't just get to point to physiology and say that it is "mind." Eray: I have tried to clarify a little. I hope my objection is more comprehensible now, sorry for the confusion in the previous post. I did my best for 6:00 am. GS: I think I see most of what you are driving at here.
