Well that was brainless. No link; no help. :-/ http://www.ecs.soton.ac.uk/~harnad/Hypermail/Foundations.Cognitive.Science2001/0158.html Thanks to Joshua Allen for pointing that out. Just a note on Harnad's commentary and we can take this private because this isn't particular to XML. On the other hand, I think the symbol grounding problem undergirds many of the discussions of WFness and the utility of schemas, the need to have a means to declare semantics, and why in some applications, predicate logic has to be augmented with other means. I think Harnad does not want to make a simplifying assumption: it does not matter to the Turing Test that we know if the computer simulation "feels". It matters that it can effectively use the symbols we recognize, the signs, and provide the illusion. The Turing Test has the problem of the grounding of the tester. One can fool some of the people some of the time, and empirical evidence with people who are not already grounded in computer technology shows this. Often, they react and expect human behavior and are only surprised when they don't get it. Competence in the simulation cannot be judged independently of the tester. I believe it is the layering of the simulation that must be accounted for. Harnad makes the mistake that for example, love is a thing we feel. Love is a verb. It is also a thing we do. Emotions are active but not necessarily intelligent except insofar as they are sign producing actions. They are not simply reflexive, as Gudwin points out, but are mediated by experience, by a local grounding in episodic memory. In the Peircean model, they are close to the real time interface between the external and internal systems of the environment and the semiote. If we compare the human to the computer, we make a mistake. If we compare the human to a network, we are closer to the physical reality of how humans process communications. Emotions create the right amount of chaos for the semiote to become creative. Those who look for reductionist means to make them predicatble will be disappointed. Those who observe them to see if they can produce novel behaviors will be delighted. len
