Moses Maimonides's Moreh Nevukhim (Guide for the Perplexed), completed around 1190 CE in Cairo, is the greatest work of medieval Jewish philosophy and one of the most influential philosophical texts of the entire Middle Ages. Written in Arabic (in Hebrew script) and addressed to his student Joseph ben Judah, who was 'perplexed' by the apparent conflict between Torah and Aristotelian philosophy, the Guide constructs a rigorous philosophical interpretation of Judaism that shaped Thomas Aquinas, Nicholas of Cusa, Spinoza, Leibniz, and the entire tradition of Jewish rationalist thought down to the present.
The Thinker and His Work
Maimonides (Rabbi Moses ben Maimon, 1138-1204) was the foremost rabbinic authority of his age, the leader of the Jewish community in Egypt, a practicing physician whose Treatise on Asthma was read by Arab and European doctors alike, and a philosopher of the first rank. His earlier Mishneh Torah had codified the entire oral Torah in Hebrew; the Guide was his attempt to resolve the crisis posed by the absorption of Aristotelian philosophy (mediated through Arabic commentators, especially Avicenna and Averroes) into the educated Jewish world. The Guide is esoterically written - Maimonides explicitly warns that not everything in it is to be taken at face value, and there is ongoing debate about what he actually believed versus what he thought was safe to say publicly.
Biblical Texts Engaged
Genesis 1 (the creation account) is the subject of Maimonides's most careful philosophical analysis. The account of the first six days, he argues, is not naive cosmology but a philosophical account of the structure of being, written in language accessible to ordinary readers but concealing deeper truths about matter, form, and the nature of divine creation. He agrees with Aristotle that the universe is probably eternal - there is no philosophical proof of creation in time - but argues that Torah teaches creation ex nihilo and that this is consistent with the evidence. The Maasseh Bereshit (Work of Creation) is one of the two great esoteric topics of the Guide, not to be taught publicly.
Exodus 3:14 ('I AM WHO I AM') is the basis for Maimonides's negative theology - the most philosophically original contribution of the Guide. God's response to Moses's question about his name is, for Maimonides, a philosophical statement: God's essence is pure existence itself, identical with being, and cannot be described by any positive predicate. To say 'God is wise' attributes to God a quality - wisdom - that is distinct from his essence, which would imply composition and limitation in God. Therefore all positive attributes of God must be understood as either attributes of God's actions (God 'acts wisely') or as negations (God is 'not ignorant').
Ezekiel 1 (the chariot vision, Maasseh Merkavah) is the other great esoteric topic. Maimonides reads the bizarre imagery of Ezekiel's vision - the four living creatures, the wheels within wheels - as a philosophical account of the structure of the cosmos: the four creatures represent the four elements or the four sublunary spheres; the wheels represent the celestial spheres. This reading demonstrates Maimonides's conviction that the prophets were philosophers who communicated metaphysical truth in the language of imagination.
Core Argument
The Guide has three main philosophical theses. First, the names of God in Scripture are all either homonyms (sharing a name but not a meaning with creaturely attributes) or negations. This preserves divine transcendence while allowing religious language. Second, prophecy is a natural phenomenon: the prophet is a person of extraordinary intellectual and imaginative development through whom the Active Intellect (the lowest of Aristotle's celestial intelligences) illuminates the passive human intellect. Third, the purpose of the commandments (mitzvot) is partly philosophical - to promote correct beliefs and proper dispositions - and partly political - to regulate the community and eliminate idolatry.
Intellectual Context
Maimonides was working within the tradition of Islamic Aristotelian philosophy (kalam and falsafa), engaging with al-Farabi, Avicenna, and Averroes. He was also responding to the kalam tradition of Islamic theology, whose methods of philosophical argument he criticized as starting from assumptions rather than evidence. His synthesis was unprecedented: a rigorously philosophical interpretation of Torah that neither compromised philosophical standards nor reduced Torah to mere allegory.
Reception and Critique
The Guide was controversial from its first circulation. Some rabbis in Provence and Spain burned it, fearing that its rationalism would undermine traditional observance. Nachmanides and later anti-Maimonidean polemicists argued that philosophy cannot be the criterion for interpreting Torah. Aquinas read the Guide (in a Latin translation, as Dux Perplexorum or Rabbi Moyses) and cited it repeatedly in the Summa Theologica - particularly on negative theology, the attributes of God, and the interpretation of Genesis 1. Spinoza, who was excommunicated by the Amsterdam Jewish community, had read Maimonides deeply; his naturalistic interpretation of prophecy in the Theological-Political Treatise is a radicalization of the Maimonidean account.
In the twentieth century, Leo Strauss's Persecution and the Art of Writing (1952) argued that Maimonides was a thoroughgoing Aristotelian who concealed his true - and irreligious - views under an esoteric surface designed to protect himself and protect ordinary believers from destabilizing truths. Strauss's reading has been enormously influential and enormously contested.
Legacy
Maimonides established negative theology as the dominant mode of philosophical theology in the Abrahamic traditions. His insistence that predicating human attributes of God is philosophically incoherent influenced Meister Eckhart, Nicholas of Cusa's docta ignorantia, and the entire apophatic (negative) theological tradition. His naturalistic account of prophecy provided the template for modern biblical criticism's attempt to explain prophetic phenomena without supernatural causation.
Key Passages
'All we understand is the fact that He exists, that He is a Being to whom none of His creatures is similar, who has nothing in common with them, who does not include plurality, who is never too feeble to produce other beings, and whose relation to the universe is that of a steersman to a boat.' (Guide I.58, trans. Friedlander)
Contemporary Relevance
Negative theology has experienced a remarkable renaissance in contemporary philosophy of religion and continental philosophy. Derrida's readings of Pseudo-Dionysius, Meister Eckhart, and negative theology in How to Avoid Speaking (1987) bring the apophatic tradition into contact with deconstruction. The question of whether God-language is cognitively meaningful - Maimonides's question - remains central to analytic philosophy of religion and theology. His synthesis of philosophical rigor and textual fidelity makes him a model for contemporary Jewish, Christian, and Muslim thinkers trying to integrate their traditions with modern intellectual standards.
