Through a BCS mailing list, I came across this web resource which is well worth checking out.
Ashby was one of the pioneers, along with people like Norbert Wiener, John von Neumann and of course Alan Turing, of the notions of cybernetics, systems theory and various related topics that came together to form what we today call the field of AI. Interestingly, many of the original founders in the earlier part of the twentieth century thought of topics like control theory and operations research as quite relevant to the study of intelligence (e.g., Ashby’s homeostat is an excellent early example of an “adaptive control system”). Today, the fragmentation into specialties makes people forget (sometimes, never aware of) many such important connections. We need more people who can emulate the breadth of the early pioneers.
