as Peirce argues in the Neglected Argument and elsewhere is, first, hypothesis formation (abduction), deduction of the implications of the hypothesis for the purpose of devising a test of it, and, once a test has been devised, finally the inductive experimental testing is made. Lessons are learned.
Thank you. That is exactly the order in my drawing. Since the cycle continues indefinitely, you can begin at any point. (For a copy of the cycle, see http://jfsowa.com/talks/cogcyc.pdf ): 1. The abduction arrow (upper left). 2. Generates hypothesis (crystal at the top). 3. Implications (prediction on the right side). 4. Testing upon the world (lower right). 5. Observation and induction to evaluate prediction. 6. Results of induction go into the soup for further reuse. Jon
perception itself, has an abductive character in Peirce’s analysis
Yes. Modern cognitive scientists agree -- even those who learned the word 'abduction' without knowing anything about CSP. But Peirce also says that the abductions during perception are not major insights. They are rather routine aspects of the observation. The abductions that generate a new hypothesis or theory are far from routine. Jon
induction for [Peirce] is more a final testing than initial conception stage
Yes. That's Gary's point (steps 5 and 6 above). But when you draw it as a cycle, no stage is "initial" or "final". I have been using versions of that cycle -- in one form or another -- for years. And I keep discovering similar cycles from other sources. I extracted a dozen slides from various talks I've presented and put them together in one short sequence: http://jfsowa.com/talks/cogcyc.pdf Slide 3: Quotations by Peirce, Whitehead, and Robert Frost to show why I use the word 'soup' instead of a more "elegant" word. Slides 7 & 8: John Boyd's OODA loop (Observe, Orient, Decide, Act). I had never heard of John Boyd until somebody in one of my lectures said "That looks like the OODA loop by John Boyd." Slide 9: The "Hierarchical Cognition Affect Architecture" by the philosopher Aaron Sloman. Slide 10: The Albus Cognitive Architecture by James Albus, who was a pioneer in using ideas from neuroscience to design AI systems. The similarities in these loops indicates that people who come from totally different backgrounds can independently converge on similar designs. Those slides contain URLs that point to articles about Boyd and by Sloman and Albus. John
