 Al-Fārābī’s intellectual background was not so much Aristotle himself. Rather it was the Aristotelian part of the syllabus of the Neoplatonic school of philosophy that flourished in Alexandria (in Egypt) in the fifth and sixth centuries (see D’Ancona 2017). Al-Fārābī tells us that eventually “instruction was moved from Alexandria to Antioch” (in Syria), until the last members of the school scattered “taking their books with them”. He says that he himself studied with one of these last members, Yūḥannā bin Ḥaylān, and together they read Aristotle up to the end of Posterior Analytics. He adds that the Alexandrian school came to describe the part of Aristotle’s Organon from modal logic onwards as “the part that is not read”, since under the Christians the modal material had been kept hidden. (Al-Fārābī’s account is in a lost work quoted by the historian Ibn Abī Usaybi‘a [‘Uyūn 604f]; see the translation in Fakhry 2002: 159.)
