wikipedia:: Principle of bivalence |
In logic, the semantic principle (or law) of bivalence states that every declarative sentence expressing a proposition (of a theory under inspection) has exactly one truth value, either true or false. [1][2] A logic satisfying this principle is called a two-valued logic[3] or bivalent logic.
the Polish formal logician Jan Łukasiewicz proposed three truth-values: the true, the false and the as-yet-undetermined.
