 As for epistemology, al-Farabi’s major work on it, the Enumeration of Sciences (Ihsa’ al-‘ulum), about the general contents of linguistics, logic, mathematical sciences, physics and metaphysics, ethics and even Islamic jurisprudence and religion, exerted an important influence over a number of Jewish scholars in the period 1200–1400. Joseph ben Judah Ibn ‘Aqnin (d. 1226), a Moroccan Jewish follower of Maimonides, inserted long sections of the original Arabic text in chapter 27 of his main ethical work, The Medicine of Souls (Tibb al-nufus); in his commentary on the Song of Songs, The Revealing of Secrets (Inkishaf al-asrar), he quoted a number of other Farabian works on epistemology, logic, metaphysics, and even music. Shem Tov Ibn Falaquera inserted a number of its passages (in Hebrew) into his own “enumeration of sciences”, part two of the Beginning of Science (Reshit hokhmah), probably written around 1250 (Efros 1935; Strauss 1936; about Falaquera’s knowledge of al-Farabi’s works, see Harvey 2002). Qalonymos ben Qalonymos translated the whole work into Hebrew in 1314, together with another short “introduction to Aristotle” by al-Farabi himself; rather significantly, he himself inserted into it his own treatment of some subjects which were lacking in the original Arabic text, very probably since al-Farabi rejected them as real sciences: medicine, alchemy, magic. Qalonymos’ version was later quoted by some Jewish scholars, mainly during the 14th and 15th centuries. As far as philosophy in general is concerned, it should be noted that Falaquera made a sort of complete Hebrew abridgement of three main works by al-Farabi, and inserted them into part three of the Beginning of Science: the Attainment of Happiness (Tahsil al-sa‘ada), the Philosophy of Plato (Falsafa Aflatun) and the Philosophy of Aristotle (Falsafa Aristu), so spreading among Jews the knowledge of the general contents of all works by Plato and Aristotle (Strauss 1936; see also Mahdi 1962). Falaquera also quoted a short introductory passage of al-Farabi’s Epistle On the Knowledge of Philosophy in his Book of Degrees (as pointed out in Chiesa and Rigo 1993).
