Titolo / Title: Epistemic Sophisms, Calculatores and John Mair’s Circle
Abstract: This paper focuses on the early sixteenth-century epistemic logic developed by John Mair’s circle and discusses iterated epistemic modalities, epistemic closure and Bradwardinian semantics related to the logic of epistemic statements. These topics are addressed as part of setting up and solving epistemic sophisms based on traditional scenarios which can be traced back to fourteenth-century British epistemic logic. While the ultimate source for the debate appears to be the second chapter of William Heytesbury’s Regule solvendi sophismata, the immediate source is the Italian editorial, commentarial and philosophical tradition, notably Paul of Venice and Cajetan of Thiene.
Keywords: Oxford Calculators; John Mair’s circle; epistemic logic; epistemic modalities; sophisms; scholastic logic.
