The Andalusian-Egyptian Jewish philosopher and physician whose Guide for the Perplexed reconciled Aristotelian philosophy with rabbinic Judaism and whose Mishneh Torah remains the most systematic codification of Jewish law ever written.
maimonides
Andalusian-born rabbinic codifier, physician, and Aristotelian philosopher (1138–1204) whose Mishneh Torah systematized the entire halakhic tradition and whose Guide for the Perplexed offered the deepest medieval Jewish engagement with Greek and Arabic philosophy.
Life
Mosheh ben Maimon — known in Hebrew acronym as Rambam and in Latin as Maimonides — was born on 30 March 1138 in Córdoba, the Almoravid Andalusian capital. His father Maimon ben Joseph was a dayyan (rabbinical judge) of the Córdoba community. The family's life was transformed when the Almohads, a Berber dynasty enforcing a rigorist Islamic orthodoxy, captured Córdoba in 1148 and gave non-Muslims the choice of conversion, exile, or death.
The Maimon family chose exile, moving first within Andalusia, then to Fez in Morocco around 1160, where the young Maimonides studied medicine and continued philosophical and rabbinic work — most likely while outwardly conforming to Islam, a controversial period addressed in his later Epistle on Forced Conversion. Around 1166 the family left Morocco for Palestine, then settled in Fustat (Old Cairo) under the more tolerant Fatimid then Ayyubid regimes.
The death of his younger brother David in a shipwreck on the Indian Ocean — David had been the family's source of livelihood as a gem merchant — left Maimonides responsible for the household. He took up medical practice. Within two decades he had become physician to the Ayyubid vizier al-Qāḍī al-Fāḍil and then to the family of Saladin himself, while serving simultaneously as nagid — the recognized head — of the Egyptian Jewish community. Maimonides's medical writings — including ten treatises in Arabic surveyed in Fred Rosner's translations — are largely synoptic and practical; his philosophical and legal work was composed in the rare hours when his medical duties allowed.
He died on 13 December 1204 in Fustat. His body was carried to Tiberias, where his tomb remains a place of Jewish pilgrimage to this day. The epitaph reads: From Moses to Moses, there arose none like Moses.
The Mishneh Torah
Completed in 1180 after ten years of work, the Mishneh Torah (Repetition of the Torah) is a fourteen-volume Hebrew codification of the entire halakhic tradition — biblical, Talmudic, Geonic — organized topically rather than by Talmudic tractate. Maimonides wrote it, as he explained in the introduction, so that a reader could know the law on any matter without working through the complex argumentation of the Talmud.
The work was controversial from its appearance. Its omission of cited sources — Maimonides simply stated the law without identifying the Talmudic passages or Geonic authorities from which he derived it — drew sharp criticism. Its inclusion of philosophical material in the Book of Knowledge (the opening volume) and its rationalist treatment of topics including the Messiah and resurrection generated continuing dispute. Yet the Mishneh Torah became one of the foundational texts of subsequent halakhic literature, taught and commented on continuously from the thirteenth century to the present.
The critical edition by Yohai Makbili (Yad Peshutah, Or Vishua, 2009–) builds on a long tradition of textual work; Eliyahu Touger's English translation (Moznaim, 1986–2007) is the standard accessible version.
The Guide for the Perplexed
The Dalālat al-Ḥāʾirīn (Guide for the Perplexed) was composed in Judeo-Arabic between roughly 1185 and 1190, addressed to Maimonides's student Joseph ben Judah ibn Shamʿun. Its express purpose: to address the perplexity of a religiously committed Jew who has also studied Aristotelian philosophy and finds the literal reading of Scripture in tension with philosophical truth.
The Guide proceeds in three parts. Part I treats the language of Scripture, arguing that biblical anthropomorphisms (God's hand, God's anger) must be read non-literally; develops the doctrine of negative theology — that nothing can be predicated positively of God; and discusses the divine attributes. Part II treats creation versus the eternity of the world (Maimonides defends creation in time but acknowledges that the philosophical arguments are inconclusive), prophecy (a naturalized account developed in conversation with Avicenna and al-Fārābī), and the relation of human intellect to the Active Intellect. Part III treats the reasons for the commandments (taʿamei ha-miṣvot), the problem of evil (Maimonides rejects the view that evil afflicts the just), divine providence (a graduated account: the species is governed by general law, individuals to the extent that they have actualized their intellects), and the human end — the perfection of the intellect culminating in love of God.
The interpretive controversies are extensive. Leo Strauss's Persecution and the Art of Writing (1952) argued that Maimonides deliberately concealed esoteric views behind exoteric statements, leading generations of readers in two opposed directions. Shlomo Pines's introduction to his translation (The Guide of the Perplexed, University of Chicago Press, 1963) is the standard scholarly account of the text and its philosophical sources. Recent work by Sarah Pessin, Kenneth Seeskin, Daniel Davies, and Josef Stern continues to debate the relation of Maimonides's stated and concealed positions.
The Philosophical Position
Maimonides's philosophy is Aristotelian in framework, mediated through the Arabic Aristotelians — particularly al-Fārābī, whom Maimonides praised as the only philosophical writer he could fully recommend, and to a lesser extent Avicenna. The metaphysical position holds that God is the necessary being, prime mover of the celestial spheres, source of the procession of intelligences that culminates in the Active Intellect — the same Avicennan cosmology, though Maimonides hedges on its full demonstration.
Negative theology distinguishes Maimonides sharply from earlier Jewish thought. No positive attribute applies to God, because every positive attribute would imply composition in God, contradicting divine simplicity. Even "existence," "unity," and "eternity" can be predicated of God only in a sense entirely distinct from what they mean of created things. The proper language for God is negative: God is not multiple, not corporeal, not contingent. This doctrine, Pines and others have traced through al-Fārābī to Plotinus and the Arabic Plotinus tradition.
Prophecy, as Maimonides treats it in Guide II.32–48, requires a triple perfection: of the rational faculty, the imagination, and the moral character. Most people lack one or more; some possess intellectual perfection without imaginative perfection and become philosophers; some possess imaginative perfection without intellectual and become diviners. Only the person who possesses all three becomes a prophet — and the highest prophet, Moses, achieved a degree of intellectual reception requiring no imaginative mediation at all. This account, naturalist in form, accommodates revelation as a natural rather than miraculous phenomenon.
The Maimonidean Controversy
The reception of the Guide was bitter. Within two decades of Maimonides's death, the rabbinic communities of Provence and Catalonia were divided over the legitimacy of his philosophical project. Solomon ben Abraham of Montpellier, a traditionalist rabbi, banned the study of the Guide and other philosophical works around 1232. David Kimhi and other Provençal rabbis countered with their own bans on the bans. The controversy intensified when the Maimonidean works were burned by the Dominicans in Paris in 1232 or 1233 — a Christian intervention that horrified all parties and helped restore an uneasy peace.
A second controversy erupted in 1303–05, when Abba Mari of Lunel and Solomon ben Adret (the Rashba) of Barcelona proposed banning philosophical study before age twenty-five. The controversy produced significant literature on both sides and ended without decisive resolution. The Provençal rationalist tradition that defended Maimonides — Levi ben Gershom (Gersonides), Moses Narboni — kept Maimonidean Aristotelianism alive in Jewish learning through the fifteenth century.
Influence Beyond Judaism
The Latin reception of Maimonides began with a translation of the Guide in the 1240s. Aquinas cites Rabbi Moyses over eighty times in the Summa and treats his arguments on creation, providence, and divine attributes with care. The position Aquinas adopts on creation in the Summa — that creation in time is a matter of revelation, not philosophical demonstration — follows Maimonides closely.
Spinoza, educated in the rationalist Sephardic milieu of Amsterdam where Maimonidean texts were familiar, both built on and broke with Maimonides. The Theological-Political Treatise (1670) cites and engages Maimonides repeatedly, accepting the rationalist framework while pushing the critique of revelation further than Maimonides would allow. The Maimonidean roots of Spinoza's biblical hermeneutics have been argued by Warren Zev Harvey, Steven Nadler, and Carlos Fraenkel.
Modern Jewish philosophy from Mendelssohn through Hermann Cohen, Yeshayahu Leibowitz, Lenn Goodman, and Menachem Kellner continues to treat Maimonides as the philosophical center of the Jewish tradition.
Significance
Maimonides is the central figure of medieval Jewish thought by any measure. The Mishneh Torah is the most systematic and continuously studied legal work in the Jewish tradition; the Guide is the most ambitious philosophical-theological synthesis attempted in medieval Judaism; and his integration of philosophical learning with rabbinic authority defined the possibility of Jewish intellectual life across the centuries that followed. The Thirteen Principles of Faith he composed for the introduction to his commentary on the Mishnah — translated into the Yigdal hymn sung in synagogues weekly — remain the closest thing Judaism has to a credal statement. He shaped not only Jewish thought but Christian Scholasticism, modern philosophy through Spinoza, and the rationalist current in Jewish learning that persists in his name.
