Galen’s Institutio Logica and al-Farabi’s Logic. A Reassessment of Parallelisms that Show a Possible Influence

The aim of the following paper is to evaluate a possible influence of Galen’s Institutio logica on al-Farabi’s logic, following Zimmermann’s and Lameer’s evidence for certain parallelisms between them. Among the scholars of al-Farabi’s logic, we find at least two authors that affirm such a textual relation, Zimmermann (1981) and Lameer (1994). However, this influence is explicitly denied by at least another study on al-Farabi’s logic, Hodges (2020). This paper then will focus on establishing what are the arguments for this influence, in Zimmermann’s and Lameer’s terms, to then re-evaluate, comparing al-Farabi’s and Galen’s writings if we can still defend that this is the case.
