Query: A Canonical Fuzzy Logic   A presentation is provided of the basic notions and operations of a) the
propositional calculus of a variant of fuzzy logic -- canonical fuzzy logic,
CFL -- and in a more succinct and introductory way, of b) the theory of fuzzy
sets according to that same logic. The propositional calculus of bivalent
classical logic and classical set theory can be considered as particular cases
of the corresponding theories of CFL if the numerical value of a specific
parameter $w$ is restricted to only two possibilities, 0 and 1.
