This article explores the rhetoric of medieval rabbi and philosopher Saadya Gaon, arguing that Saadya typifies what LuMing Mao calls the “interconnectivity” of rhetorical cultures (Mao 46). Suggesting that Saadya makes use of argumentative techniques from Greek-inspired, rationalist Islamic theologians, I show how his rhetoric challenges dominant works of rhetorical historiography by participating in three interconnected cultures: Greek, Jewish, and Islamic. Taking into account recent scholarship on Jewish rhetoric, I argue that Saadya's amalgamation of Jewish rhetorical genres alongside Greco-Islamic genres demonstrates how Jewish and Islamic rhetoric were closely connected in the Middle Ages. Specifically, the article analyzes the rhetorical significance of Saadya's most famous treatise on Jewish philosophy, The Book of Doctrines and Beliefs, which I argue utilizes Greco-Islamic rhetorical strategies in a polemical defense of rabbinical authority. As a tenth-century writer who worked across multiple rhetorical traditions and genres, Saadya challenges the monocultural, Latin-language histories of medieval rhetoric, demonstrating the importance of investigating Arabic-language and Jewish rhetorics of the Middle Ages.
