João Mair e a teoria tardomedieval da consequência lógica

This paper approaches the reception of the late-medieval account of logical consequence in John Mair (†1550). The paper briefly compares Mair’s account of formal consequence with Buridan’s, and it aims to revisit the characterization of a Parisian and a British tradition concerning the division of formal and material consequence. Although Mair clearly incorporates Buridan’s account, I aim to show that Mair’s Liber Consequentiarum points towards original developments within that tradition.
