But this "how it works" is ambiguous because there are many ways of knowing "how it works." Eg, one way to know how something works is describing the underlying implemetnation - for human intelligence, I then have to describe things in terms of neurophysiology. But another, perhaps more illuminating way of describing "how it works" is in terms of the information processing that has to go on to support the activity that is called intelligent. What is sought then is an implementation-free description of "how it works." You might call it a "Knowledge Level Architecture." This would be a level of intelligent system description above the symbol level, but below the KL (as described by Newell). In fact, I *did* call it that in Sticklen, J. (1989). Problem Solving Architectures at the Knowledge Level. Journal of Experimental and Theoretical Artificial Intelligence. 1 (pp. 1-52). ---jon---
