Truth and Borderline Cases

摘要: According to the principle of bivalence, truth and falsity are jointly exhaustive mutually exclusive options for a statement. It is either true or false, not both, even in borderline case. That highly controversial claim central epistemic theory vagueness, which holds that cases distinguished by special kind obstacle knowing truth-value But this paper defence theory. If bivalence holds, it presumably does so as consequence what separately are. One may therefore expect be derivable from combination some principles characterizing other falsity. Indeed, such derivations easily found. Their form will course depend on initial characterizations falsity, all permit derived. This focusses relation between its derivability about Borderline vague expressions primary examples an urgent challenge bivalence.
