The title of her talk: Medieval Aristotelian Logic: the syllogism according to Radulphus Brito (1290s) and John Buridan (1320s)
ABSTRACT
This presentation summarises the findings of three papers on medieval Aristotelian logic (2021, 2024 and 2025). First, I show that medieval Aristotelian logic is best understood as a theory of scientific methods. This theory encompasses a formal enterprise, but is not centred around it. Medieval Aristotelian logic is, rather, a theory of the syllogism, with the syllogism being understood as a tool for producing and transmitting scientific knowledge. I then focus on two pivotal authors from this period: Radulphus Brito and John Buridan. Radulphus Brito presents the most coherent version of thirteenth-century Aristotelian logic, offering a pragmatic perspective on the syllogism. John Buridan, in turn, introduces significant changes to the medieval logical tradition. Among other things, he does this through his 'substantial form of the syllogism', which amounts to the reification of syllogistic form. This represents a radical departure from Brito and the thirteenth-century tradition, which considered syllogistic form merely as a 'mental consideration'. Buridan's approach must be viewed as a subtle yet significant advancement in the history of logic, marking a shift towards considering logical form as an abstract entity and establishing logic as a formal discipline.
