Řešení sémantických paradoxů v De vero et falso Stanislava ze Znojma

Miroslav Hanke

This paper deals with the solution to semantic paradoxes proposed at the beginning of the fifteenth century by the Czech philosopher and theologian Stanislaus of Znaim (d. 1414) in his treatise De vero et falso. Stanislaus distinguishes among various meanings of the terms "true" and "truth", of which the semantic concept of truth is crucial as far as paradoxes are concerned: truth is defined in terms of correspondence with an objective state of affairs, while falsity in terms of failure of such correspondence. Paradoxes are conceived as paradoxical deductions of the falsity of propositions from their hypothetically assumed truth and vice versa. According to Stanislaus' solution, no genuinely paradoxical situation is acceptable and the existence of implicit and hidden meaning of potentially paradoxical propositions is required. Given these assumptions, potentially paradoxical propositions are regarded as true and according to different and unconnected meanings. These results, despite their atypical theological formulation and substantiation, remind one strongly of William Heytesbury and Pierre d'Ailly, and hence the hypothesis of their impact on Stanislaus suggests itself.
