Richard, I long ago proposed a working definition of intelligence as "Achieving complex goals in complex environments." I then went through a bunch of trouble to precisely define all the component terms of that definition; you can consult the Appendix to my 2006 book "The Hidden Pattern"....
I'm not sure if your "working definition" is supposed to be significantly less ambitious than a philosophical definition or perhaps you even address something like this in your appendix, but I'm wondering whether the hypothetical example of Blockhead from philosophy of mind creates problems for your definition. Imagine that a computer has a huge memory bank of what actions to undertake given what inputs. With a big enough memory, it seems it could be perfectly capable of "achieving complex goals in complex environments." Yet in doing so, there would be very little internal processing, just the bare minimum needed to look up and execute the part of its memory corresponding to its current inputs. I think any intuitive notion of intelligence would not count such a computer as being intelligent to any significant degree no matter how large its memory bank is or how complex and diverse an environment its memory allows it to navigate. There's simply too little internal processing going on for it to count as much more intelligent than any ordinary database application, though it might of course, do a pretty good job of fooling us into thinking it is intelligent if we don't know the details. I think this example actually poses a problem for any purely behavioristic definition of intelligence. To fit our ordinary notion of intelligence, I think there would have to be at least some sort of criteria concerning how the internal processing for the behavior is being done. I think the Blockhead example is normally presented in terms of looking up information from a huge memory bank, but as I'm thinking about it just now as I'm typing this up, I'm wondering if it could also be run with similar conclusions for simple brute search algorithms. If instead of a huge memory bank, it had enormous processing power and speed such that it could just explore every single chain of possibilities for the one that will lead to some specified goal, I'm not sure that would really count as intelligent to any significant degree either. -Ku http://www.umich.edu/~jsku ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=11983
