Definition of bivalence in English:



  • The existence of only two states or truth values (e.g., true and false)

    • ‘In this case, the semantic theory used incorporated the principle of bivalence: every sentence was assigned either the value true or the value false.’
    • ‘Against both Epicurus and the Stoics, Carneades argued that no deterministic consequences follow from the principle of bivalence (the principle that for any statement P, either P is true or P is false).’
    • ‘So we may represent the Aristotelian solution as one which rejects the law of bivalence.’
    • ‘Against the Stoics he argued that a commitment to bivalence and the principle that every action has a cause does not entail that all actions are fated.’
    • ‘Provided that Diodorus accepted the principle of bivalence, these definitions, too, satisfy the modal requirements to above, as can be checked easily.’
