摘要

Our thesis about contradictoriness is a threefold one: it is a relative, theory-dependent concept; it is a synonym of absurdity, which is a constant of falsity; it is to be used as a definiens of sentential negation and truth-values, contrary to its usual presentation. First of all, we review both the motivation of such a thesis and its philosophical consequences about the nature of negation and truth-values. Then we propose a formal background encompassing the relativity of contradictoriness into a set of increasingly complex question-answer games, explicating the variety of its formulations by a variety of available answers that make sense of truth-values.
