  1. countableuncountablemathematicsA form of reasoning, derived from fuzzy set theory, whereby a truth value need not be exactly zero (false) or one (true), but rather can be zero, one, or any value in between.

    Whereas ordinary logic deals with statements of absolute truth (such as, “Is this object green?”), fuzzy logic addresses sets with subjective or relative definitions, such as “tall,” “large,” or “beautiful.”
