Fuzzy logic (Zadeh, Kosko, etc) developed up to its more simple version of it: YinYang Fuzzy Bipolar Equilibirum (Zhang).
The problem that fuzzy logic overcomes is that the so called «Formal» logic is trying to be «The parent logic of all logics» by meaning that any dualism is necessarily adversarial (truth or false) while it can’t prove it (i.e. this phrase and its language is false). So since we can’t find such an issolated 1 and we need it to see it realtive to another in a relation, a relation of 2 is the minimum unit we can reasonable approach. More exactly speaking, since elements are relative within the relation, a final more clear relation (or unity) is a total of all relations within elements of a set, and not only the ones following some ranks or linearity in there. I.e. One accurate unity is the outcome of a retrograde relation between 2 (i.e. niyan). All 6 replies from this test about ranks are equally true (there are not ranks of truth for them).
Dual should simply mean that there are 2 parts (of a united constant) in a temporarily reducted whole. Dual doesn’t and shouldn’t mean that the relation is rival-adversarial or each one of the 2 are static or absolute, just because in essence they are always relative, and so are just different (maybe opposed-antagonist but not rival) poles. This is why some people use Bipolar instead of Dual, for meaning that Bipolar is not Rival, but we should risk in bringing back the reminder of: «Dual can be antangonist, but not even that is necessarily adversarial».
Within any duality, we will always find aesthetics that will help us to differentiate the properties of each of the two polarities. Since dualities are scalar and grown out from the same essential simplifiable mechanism, aesthetics differentiate the poles always in the same basic way.. I.e. when a dualism gets complexer, one pair will still be Yin (Femenine) and the other Yang (masculine), same for the seconds and the thirds of a triad.
So «dual fuzzyness» or «dual constant» are the better terms to use when we talk about the relation within a duality, or the most simplified form of truth.
Fuzzy is parent and or primary pole of cartesian dualism for logic, just because a duality seems realer when it is interpreted as a fuzzy constant.
