Workshop on the History of Arabic Logic

May 7 - May 8

Event Navigation

The Workshop on History of Arabic Logic has two main aims: to make better known the richness and importance of Arabic logic, that is, logic developed and studied in Arabic-speaking lands from the 8th to the 15th centuries CE; and to provide a forum for interaction and discussion by scholars of Arabic logic.

Since the last century, scholars have acknowledged the original and relevant contribution of medieval Arabic philosophers and thinkers to the development of medieval Western logic and, more generally, to the history of logic.
The study of logic in Arabic began with the translation project undertaken in the eighth century CE during the Umayyad era, and fostered by the Abbasid Caliphate, whose capital was Baghdad, to make the great works of Greek science, including those of Aristotle, accessible to the Arabic world. The study of Aristotle led in time to important and original creations by such figures as al-Farabi in the tenth century and Avicenna (Ibn Sina) in the eleventh, Fakhr al-Din al-Razi in the twelfth, and al-Tusi in the thirteenth. Avicenna, in particular, introduced novel ideas on the hypothetical syllogism, and on modal and temporal logic. A modified Avicennan logic took the place of Aristotelian logic in Arabic studies of the subject after his time.
Arabic logic had a strong but largely indirect influence on Latin medieval logic. Although translations of small parts of al-Ghazali’s and Avicenna’s logic (in a broad sense) were transmitted in Latin, the influence came mainly through translations of the Aristotelian commentaries of Averroes, who was working in Cordoba in Muslim Spain in the twelfth century, in close contact with Christendom.
