I should think it would be clear that if I were not enjoying this discussion, I would not continue it.

Bill, your point is well made, and I plead guilty to asserting a generality. However, just for example, if you look at Skinnerian reasoning, his effort to reduce all mental processes to S==>R complexes is a classic example. Marvin Minsky is another, although he is less dedicated to S-R than he is to software subroutines. To me, looking at this torturous analyses, the simple use of ability and perception is like the elephant in the parlor that no-one talks about. Very Victorian.
