Solutions to the Knower Paradox in the Light of Haack’s Criteria

Abstract The knower paradox states that the statement ‘We know this is false’ leads to inconsistency. This article presents a fresh look at and some well-known solutions from literature. Paul Égré discusses three possible modal provability logic provides for by surveying comparing different interpretations of modality, originally described Skyrms, Anderson, Solovay. In article, background explained clarify Égré’s solutions, all which hinge on intricacies its arithmetical interpretations. To check whether are satisfactory, we use criteria paradoxes defined Susan Haack propose refinements them. aims describe what extent can be solved using proposed in literature satisfy Haack’s criteria. Finally, offers reflections relation between knowledge, proof, provability, as inspired solutions.
