It is the pairedness of the two."] qualities, at spatial and temporal boundaries of emergence, not unrelated to the very brief exchange Joe and I had a week or so back on ontological/metaphysical asymptotes, so to speak. The very fine introduction to RLT of Ketner and Putnam spells it out fairly succinctly.   Thank you so much.  I just placed an order for that collection.  I unfortunately only have the Essential Peirce at home. Does he arrive at a scheme of fuzzy logic akin to Zadeh's? That is, even from my readings I can see how Peirce's thought entails fuzzy logic.  Due to his doctrine of continuity and vagueness if nothing else.  I just wasn't aware how explicit he made this logically.
