Biblical Narrative
He was born in the Faiyum oasis of Egypt around the year 882, in a village whose name has not survived, the son of a man named Joseph. By the age of twenty he had completed a Hebrew dictionary; before he was thirty he had written, in Hebrew, a polemic against the Karaite teacher Anan ben David that traveled the trade routes of the Mediterranean and arrived in the academies of Babylon. The rabbis there took note. There was something at work in this Egyptian — a fluency in Arabic and Hebrew, a courage in disputation, a ferocious appetite for system — that the venerable but tired academies of Sura and Pumbedita had not seen in generations.
In 928, when the academy of Sura was on the brink of closing, the exilarch David ben Zakkai called Saadia from his exile in Aleppo and made him gaon — head of Sura — over the heads of older candidates. The choice scandalized some and saved the academy. Within months Saadia had reorganized the curriculum, summoned new students, written new responsa, and begun the work that would define him: the translation of the Hebrew Bible into Arabic, with running commentary. He called it the Tafsir, and for a thousand years it would be read by Jewish children from Yemen to Andalusia as their first introduction to Scripture.
He fought the Karaites who denied the Oral Torah. He fought the calendrical reformer Ben Meir who tried to take Passover-dating away from Babylon. He fought his own patron, the exilarch David, when David demanded a corrupt ruling — and was deposed for two years and excommunicated, and then reinstated and made gaon again because no one else could fill the seat. In the years of his deposition he wrote his masterpiece, Emunot ve-Deot — Beliefs and Opinions — the first systematic Jewish philosophy, in Arabic, modeled on the Mu'tazilite kalam of his Muslim contemporaries.
He died in 942, weakened by the illnesses of a man who had argued with the world for sixty years. He left behind a Tafsir, a Siddur (the first printed Jewish prayer book), a polemic against Anan, the Beliefs and Opinions, a Hebrew grammar (Sefer ha-Egron), and dozens of responsa. He had translated the Bible into the language his people now spoke. He had given Judaism its first philosophical defense in the language of philosophy. The geonim before him had been transmitters; he had made the academy a place where new things could be made — and the long Jewish argument about reason and revelation, an argument that would run from him through Maimonides to the present, opened with his books.
It is necessary that man should investigate every matter, until he reaches the truth — for if he relies merely on tradition, he closes the door before himself.Saadia Gaon, Emunot ve-Deot, Introduction §6

Saadia ben Joseph al-Fayyumi (882-942 CE), known in Hebrew as Saadia Gaon, is the central figure of geonic-period Judaism and the founder of medieval Jewish philosophy and biblical translation. Born in the Faiyum, educated in Egypt, exiled to Aleppo and then to Baghdad, he served as gaon (head) of the academy of Sura from 928 until his death, with a two-year deposition (932-934) over a dispute with the exilarch David ben Zakkai. The standard biography is Henry Malter's Saadia Gaon: His Life and Works (JPS 1921), supplemented by Robert Brody's The Geonim of Babylonia and the Shaping of Medieval Jewish Culture (Yale 1998).
Saadia's Tafsir — his Judeo-Arabic translation-commentary on the Pentateuch — was the first complete Arabic version of the Bible by a Jew. It became the standard Bible of Jews in the Arabic-speaking world for centuries, transmitted in dozens of medieval manuscripts and printed in the Constantinople Polyglot of 1546. The Cairo Geniza has yielded extensive autograph fragments. Modern critical editions include Joseph Derenbourg's Versions Arabes du Pentateuque (Paris 1893) and the ongoing scholarly project by Yefet Ratzaby and others.
His Sefer ha-Emunot ve-ha-De'ot (Kitab al-Amanat wa'l-I'tiqadat in the Arabic original; The Book of Beliefs and Opinions in English), composed in 933 during his deposition from Sura, is the first systematic Jewish philosophical treatise. Drawing on Mu'tazilite Islamic kalam, it covers creation, divine unity, command and prohibition, reward and punishment, free will, the soul, and the messianic future. Saadia argues that reason and revelation cannot conflict and that proper interpretation reconciles them. Alexander Altmann's translation (Yale 1948, abridged) and Samuel Rosenblatt's complete English version (Yale 1948) remain standard.
Saadia's polemic against the Karaites — particularly his Refutation of Anan (Kitab al-Radd 'ala 'Anan) — defined the geonic Rabbanite-Karaite boundary for the next two centuries. Karaism, the movement founded by Anan ben David in eighth-century Babylonia, rejected the authority of the Talmud and held to scripture alone. Saadia's polemic, surviving only in fragments, structured the Rabbanite response. The Cairo Geniza has yielded much of his other lost works, including portions of the Hebrew grammar Sefer ha-Egron, biblical commentaries, and dozens of responsa. Norman Solomon's introduction to the Yale Judaica Saadia volume and Daniel Lasker's articles on Karaite-Rabbanite polemic provide modern syntheses.
Saadia is the hinge of medieval Judaism: behind him lie the Talmudic and geonic centuries; ahead, the philosophical, lexicographical, and exegetical world of Andalusi Jewry. Without his Tafsir, no Maimonides; without his polemics, no Karaite-Rabbanite settlement.Adapted from Robert Brody, The Geonim of Babylonia
