 Little is known about Isaac Albalag. All that we know about him is that he lived in the second half of the thirteenth century either in Catalonia or Provence (Sirat 1985: 238). References to Albalag in the medieval Jewish literature indicate that he was not a figure of favorable reputation. His name appears in a number of Jewish writings usually in association with humiliating accusations of heresy. The Kabbalist Shem Tov Ibn Shem Tov (d.1440), for instance, accuses Albalag of heresy for advocating a heretical view regarding the fate of the human soul (Sefer ha ʾemunot [the Book of Beliefs], I:1). In Sefer Neveh Shalom (Indwelling of Peace), the fifteenth-century Spanish thinker Abraham Shalom attacks Albalag for eliminating the doctrine of creation by radically naturalizing the account for celestial motion (Vajda 1960: 271). Albalag’s worth as a philosopher did not go unnoticed, notwithstanding. Isaac Polqar (14th century), the author of ʿEzer ha-dat (The Support of Faith) holds Albalag in great esteem and cites him approvingly in dealing with the controversial issue of the origin of the world (ʿEzer ha-dat: part II: p.46).
