A Comparative Study of Ibn al-Muqaffaʿ and Porphyry’s Isagoge

One of the important voids in Iranian, even World, logical Studies is absence of a comprehensive History of Islamic Logic. The works has been done in the East and West hitherto are steps for peregrinating a long road which should be continued many years. Writing a history of Islamic Logic naturally should be begun by the study of the development of Porphyry’s Isagoge, a book that always was the first part of all logical writings in the history of Islamic Logic. Doing this, in turn, should be begun by the study of Ibn al-Muqaffaʿ’s Isagoge, a paraphrase that firstly introduced Porphyry’s Isagoge to the Islamic World.
