Abstract [eng] |
The aim of our study is the analysis of Boethius’ solution to the Aristotelian ‘sea-battle paradox’ in his second commentary on De interpretatione. There Boethius offers an original way out of the paradox that contains two conflicting propositions – the principle of bivalence which requires each sentence to have a determined truth value ‘true’ or ‘false’, and the open future intuition according to which more than one future state of affairs is possible. By engaging in the long-lasting controversy about Boethius’ contribution to the tradition of indeterministic logic we argue that the indefiniteness operator – indefinitus – first found in Boethius’ commentary was meant to perform a modal function and in such way enable propositions which are true but not necessary. |
