Medieval Logic
The scholastic and Islamic logicians: supposition theory, modal syllogistic, and the bridge from the ancients to the moderns.
- The problem
- How do words refer inside arguments, and how should necessity and time enter the syllogism?
- The turning point
- Theories of supposition (reference) and a developed modal–temporal syllogistic, with Avicenna and Ockham at the summit.
- An open question
- How much medieval and Arabic logical insight remains untranslated and unread by the modern field?
The Canon
- al-Shifāʾ: The Logic c. 1027
