The principle of bivalence
WebbWe would then give up the principle of bivalence, that every sentence is either true or false, and accept more alternatives, e.g. that (30) is neither true nor false. This will or will not save Davidson's biconditional (1), depending the choice of three-valued semantics. WebbFor given the identification of truth with supertruth, the law of bivalence becomes: Bivalence: For every meaningful sentence P, either P is true in every admissible interpretation or P is false in every admissible interpretation, and we have just seen that this has counterexamples.

WebbIn 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. A logic satisfying this principle is called a two-valued logic or bivalent logic. WebbAs for the principle of bivalence, it does seem likely that it cannot be a theorem of a verificationist theory of meaning (if only because it cannot be expressed therein), but this needs argument and, besides, the principle of bivalence, while …

Webb14 dec. 2004 · The principle of bivalence basically says that implies P is false, or rather, that if P is not true, then it is false (and vice versa). This is a slightly stronger condition. If we say that "this statement is false" is a proposition (which is arguable), then the LNC simply says that it is not both true and not-true. solution focused therapy scalingWebbrejected the principle of logic bivalence, while the Stoics accepted it and strongly advocated determinism [4, p. 8].
