Moses ben Maimon was born in 1138 CE in Córdoba, the same city that had produced Averroes twelve years earlier. His father Maimon was a judge and scholar; young Moses grew up in the golden twilight of Andalusian Jewish culture. But in 1148, the Almohads conquered Córdoba and ended the tolerance. Jews faced conversion, exile, or death. The family chose exile.
For years, they wandered — through Spain, perhaps through Provence, eventually to Fez in Morocco. The Almohads ruled there too, but enforcement was laxer. Maimonides studied secretly: Torah, Talmud, philosophy, medicine, astronomy. His father wrote treatises encouraging Jews who had converted under duress. It was a precarious existence — living as hidden Jews in a hostile empire.
Around 1165, the family moved again: to Palestine (briefly — the Crusader states were no haven), then to Egypt, settling in Fustat (Old Cairo). The Fatimid caliphate tolerated Jews; Maimonides could live openly. His brother David became a merchant, supporting the family while Moses studied and wrote.
Then catastrophe. Around 1169, David drowned in a shipwreck in the Indian Ocean, taking the family fortune with him. Maimonides was devastated. He wrote that for nearly a year, he lay sick with grief, boils, fever, unable to function. When he recovered, he had to support David’s widow and daughter as well as his own family. He turned to medicine.
His medical career flourished. He became court physician to al-Fadil, Saladin’s vizier, and later to Saladin’s son. His days were consumed: traveling to the palace, treating the royal household, returning exhausted to find crowds of patients — Jews and Muslims — waiting at his home. He doctored until nightfall, ate lying down from fatigue, and then turned to his real work: answering legal questions from Jewish communities across the world, and writing philosophy.
His legal masterpiece, the Mishneh Torah, was fourteen books codifying all of Jewish law — the first comprehensive code since the Talmud. Systematic, clear, written in elegant Hebrew, it aimed to make the oral law accessible. Controversial, too: he omitted sources, deciding cases definitively rather than presenting debates. Some saw this as arrogance; others as necessary clarity.
His philosophical masterpiece, the Guide for the Perplexed (Moreh Nevukhim), was addressed to a student torn between philosophy and faith. Written in Arabic (in Hebrew script), it harmonised Aristotelian philosophy with biblical religion through careful interpretation. God is unknowable, describable only through negation: not corporeal, not multiple, not limited. The Torah speaks in “the language of human beings,” using anthropomorphisms that the wise interpret allegorically. The law’s commandments have rational purposes, even when not obvious. The goal of human life is intellectual perfection — knowledge of God to the extent possible.
The Guide was explosive. Traditionalists banned it; philosophers treasured it; communities split. But it shaped Jewish philosophy permanently. When Aquinas cited “Rabbi Moses,” he meant Maimonides. When Spinoza wrestled with Jewish thought, he wrestled with Maimonides.
Maimonides died in 1204 CE, exhausted, mourned throughout the Jewish and Muslim worlds. The saying arose: “From Moses to Moses, there arose none like Moses” — from the biblical Moses to Maimonides, no one comparable. His tomb in Tiberias remains a pilgrimage site. His works remain studied, debated, lived.
