Critical Preface: The Paradox of Two Legacies

THE PARADOX: History’s Most Influential Forgotten Philosopher

Abu al-Walid Muhammad ibn Ahmad ibn Rushd (Latinized: Averroes, 1126-1198) occupies a unique position in intellectual history. In medieval Christian Europe, he was simply “The Commentator”—his interpretation of Aristotle was THE standard for 300+ years. Thomas Aquinas cited him hundreds of times. Dante placed him in Limbo with history’s greatest philosophers. Universities required his commentaries.

Yet in the Islamic world where he lived and wrote, his philosophy was largely forgotten within a century of his death.

Two Radically Different Legacies:

In Latin Christian Europe:

• The authoritative interpreter of Aristotle
• Read, debated, refuted, celebrated for centuries
• Sparked the “Averroist” controversy
• Influenced virtually every major scholastic philosopher
• Standard curriculum at Paris, Oxford, Padua until 1600s

In the Islamic World:

• Largely ignored after 1200
• Few manuscripts preserved
• Not studied in madrasas
• Philosophical tradition he represented declined
• Remembered more as jurist than philosopher

Why This Happened:

1. Timing: Al-Ghazali’s critique of philosophy gained dominance
2. Geography: Ibn Rushd lived in Muslim Spain/Morocco (periphery)
3. Politics: Almohad persecution of philosophers late in his life
4. Intellectual Climate: Philosophy increasingly seen as dangerous to faith
5. Translation: His works translated to Latin but not widely copied in Arabic

What We Know with Certainty:

HISTORICALLY VERIFIED:

• Born 1126 CE in Cordoba, Al-Andalus (Muslim Spain)
• Family of prominent judges (qadis)
• Served as qadi in Seville, then Cordoba
• Court physician to Almohad caliphs
• Wrote extensive commentaries on Aristotle
• Wrote The Incoherence of the Incoherence defending philosophy
• Fell from favor late in life; books burned
• Died 1198 CE in Marrakesh, Morocco
• Left approximately 80-100 works (most survive)

PRIMARY SOURCES:

1. Ibn Rushd’s Own Works – Survive mostly in Latin/Hebrew translations (Arabic originals often lost)
2. Contemporary Biographical Notices – Limited but reliable
3. Later Biographies – Al-Ansari, al-Marrakushi (13th-14th centuries)
4. Court Records – Documented his positions as qadi and physician
5. Dante’s Testimony – Places him in Limbo (Divine Comedy, Inferno IV)

SOURCE PROBLEM:

Unlike Ibn Sina, we have:

• No autobiography
• Limited contemporary biographical material
• Many works survive ONLY in Latin/Hebrew (Arabic lost)
• Details of personal life sparse
• Political downfall poorly documented

But we do have:

• Dated manuscripts
• Clear attribution of major works
• Extensive corpus (commentaries, original works)
• Documentation of public positions

This Document’s Approach:

Focuses on:

• Verified biographical facts
• Major philosophical contributions
• The Aristotle commentaries
• Defense of philosophy vs. al-Ghazali
• Dual legacy (Islamic/Christian worlds)
• Why he matters for understanding medieval thought

Part I: Life and Historical Context

Al-Andalus: The Western Edge of Islamic Civilization

Historical Setting:

Ibn Rushd lived in Al-Andalus (Muslim Spain)—the westernmost extension of Islamic civilization, geographically and culturally distant from Baghdad and the eastern Islamic heartlands.

Political Context (12th Century):

The Almohad Dynasty (1121-1269):

• Berber dynasty from Morocco
• Conquered Al-Andalus and North Africa
• Initially supported learning and philosophy
• Became increasingly orthodox/intolerant
• This shift would destroy Ibn Rushd’s career

Cultural Context:

Al-Andalus (especially Cordoba) was:

• Center of learning, libraries, translation
• Mix of Muslim, Christian, Jewish scholars
• Philosophy, medicine, astronomy flourished
• But always under pressure from Christian reconquista
• And from conservative religious authorities

The Reconquista:

Christian kingdoms were reconquering Iberia:

• Toledo fell 1085 (before Ibn Rushd’s birth)
• Constant military pressure
• This context of siege influenced everything
• Cordoba would fall 1236 (after Ibn Rushd’s death)

Intellectual Climate:

Philosophy in Crisis:

• Al-Ghazali’s critique (late 11th century) had cast doubt on philosophy
• Growing tension between philosophers (falasifa) and theologians
• Philosophy seen as threat to Islamic orthodoxy
• Ibn Rushd would attempt to defend philosophy

Family and Early Education (1126-1153)

Birth (April 14, 1126)

Born in Cordoba, Al-Andalus (modern Spain). His full name: Abu al-Walid Muhammad ibn Ahmad ibn Muhammad ibn Rushd.

Distinguished Family:

Grandfather: Muhammad ibn Rushd (1058-1126)

• Famous jurist and qadi (judge)
• Expert in Maliki school of Islamic law
• Died same year grandson was born

Father: Ahmad ibn Rushd

• Also served as qadi
• Legal scholar

The family name “Ibn Rushd” was associated with legal authority and learning.

Traditional Islamic Education:

Young Ibn Rushd studied:

Religious Sciences:

• Quran (memorized)
• Hadith (traditions of Prophet Muhammad)
• Fiqh (Islamic jurisprudence—Maliki school)
• Theology (kalam)

Arabic Language:

• Grammar
• Literature
• Poetry

Rational Sciences:

• Medicine (studied with leading physicians)
• Philosophy (dangerous subject—studied privately)
• Mathematics and astronomy
• Logic

Early Career Path:

Expected to follow family tradition:

• Become jurist
• Serve as qadi
• Teach Islamic law
• Advise rulers

Philosophy was a private passion, not a career.

Medical and Philosophical Training (1153-1169)

Medical Studies:

Trained with:

• Abu Ja’far Harun al-Tajali (leading physician)
• Studied Galen, Hippocrates, al-Razi, Ibn Sina
• Became skilled physician

Philosophical Education:

Studied philosophy privately:

• Aristotle’s works (in Arabic translation)
• Al-Farabi’s commentaries
• Ibn Sina (Avicenna)—whom he would later critique
• Ibn Bajja (Avempace—Andalusian philosopher)
• Ibn Tufayl (philosopher who would mentor him)

Why Privately?

Philosophy was controversial:

• Some religious scholars considered it heretical
• Could damage career prospects
• Safer to study quietly

Early Writings:

By 1150s, began writing:

• Medical treatises
• Commentaries on Aristotle (early versions)
• Legal opinions (fatwas)

The Crucial Patronage: Meeting Ibn Tufayl (1169)

The Introduction:

Ibn Tufayl, court philosopher/physician to Caliph Abu Yaqub Yusuf, arranged meeting between young Ibn Rushd (age 43) and the caliph.

The Famous Meeting (Ibn Rushd’s Account):

The caliph asked Ibn Rushd: “What is the opinion of the philosophers about the heavens? Are they eternal or created?”

Ibn Rushd hesitated—dangerous question. Wrong answer could mean persecution.

The caliph, seeing his fear, engaged Ibn Tufayl in discussion, demonstrating his own knowledge of philosophy. Ibn Rushd relaxed and joined the conversation.

The caliph was impressed.

The Commission:

Caliph Abu Yaqub asked Ibn Rushd to write commentaries on Aristotle:

• Aristotle’s Arabic translations were difficult
• Needed clear, systematic exposition
• Would serve scholars throughout the empire

Why This Mattered:

• Official patronage meant safety to write philosophy
• Resources and time for massive project
• Access to libraries and manuscripts
• But also made him vulnerable to political changes

Career Under Almohad Patronage (1169-1195)

Official Positions:

1169: Appointed qadi (judge) in Seville 1171: Appointed qadi in Cordoba (his hometown) 1182: Appointed chief physician to Caliph Abu Yaqub Yusuf 1184: Chief qadi of Cordoba (highest judicial position)

Simultaneously:

Writing prolifically:

• Commentaries on Aristotle (short, middle, long versions)
• Original philosophical works
• Medical encyclopedia
• Legal treatises

Daily Life:

• Morning/daytime: Judicial duties, medical practice
• Evening/night: Writing and study
• Reportedly wrote average 10,000 words per day
• Continued for 30+ years

His Patron Dies (1184):

Caliph Abu Yaqub Yusuf died. Succeeded by his son Abu Yusuf Yaqub al-Mansur.

New Caliph:

Al-Mansur initially continued supporting Ibn Rushd:

• Kept him as court physician
• Allowed philosophical work to continue
• But political winds were changing

The Great Works Period (1174-1195)

During these 20+ years, Ibn Rushd produced:

Aristotle Commentaries (His Major Achievement):

Three Types:

1. Short Commentaries (jami): Summaries/introductions
2. Middle Commentaries (talkhis): Paraphrases with explanations
3. Long Commentaries (tafsir): Line-by-line analysis with Ibn Rushd’s own views

On Most of Aristotle’s Works:

• Logic (Organon)
• Physics
• De Caelo (On the Heavens)
• De Anima (On the Soul)
• Metaphysics
• Nicomachean Ethics
• Politics
• Poetics
• Rhetoric
• Various natural science works

Original Philosophical Works:

1. Tahafut al-Tahafut (The Incoherence of the Incoherence)—c. 1180

• Response to al-Ghazali’s attack on philosophy
• Defense of philosophical inquiry
• Point-by-point refutation

2. Fasl al-Maqal (Decisive Treatise)—c. 1179

• On relationship between philosophy and religion
• Argues they cannot truly conflict
• Defends philosophical interpretation of scripture

3. Kitab al-Kashf (Exposition of Religious Arguments)

• Popular theology
• Accessible arguments for God’s existence
• Bridge between philosophy and masses

Medical Works:

4. Kitab al-Kulliyat fi al-Tibb (The Generalities of Medicine)

• Medical encyclopedia
• Translated as Colliget in Latin
• Complements Ibn Sina’s Canon
• More theoretical/systematic than clinical

Legal Works:

5. Bidayat al-Mujtahid (The Distinguished Jurist’s Primer)

• Comparative Islamic jurisprudence
• Analysis of different legal schools
• Still used in Islamic legal studies today
• Major work of fiqh

Plus numerous other treatises on astronomy, physics, theology, logic.

The Fall from Grace (1195-1198)

Political Context:

By 1195, Caliph al-Mansur faced:

• Military pressure from Christian kingdoms
• Internal dissent
• Religious conservatives demanding orthodoxy
• Need to appear pious/orthodox to maintain power

The Purge of Philosophers:

In 1195, al-Mansur suddenly:

• Dismissed Ibn Rushd from all positions
• Exiled him to Lucena (small town near Cordoba)
• Ordered his philosophical books burned publicly in Cordoba
• Banned study of philosophy (except astronomy/medicine)
• Persecuted other philosophers and scientists

Why?

Political Calculation:

• Al-Mansur needed support of orthodox religious scholars (ulama)
• Philosophy was controversial/suspect
• Sacrificing philosophers gained political capital
• Defense against Christian reconquista required unity

Charges Against Ibn Rushd (Possibly):

1. Teaching philosophy (now forbidden)
2. Preferring philosophy over theology
3. Calling animal in Quran a giraffe instead of by Quranic name (disrespecting sacred text)
4. Various other accusations

Historical Uncertainty:

Details are unclear—sources are sparse. We know:

• He was disgraced publicly
• Exiled to Lucena
• Books burned
• But not executed or imprisoned long

Partial Rehabilitation:

After 18 months exile in Lucena:

• Al-Mansur recalled him to Marrakesh (Morocco)
• Restored to favor (somewhat)
• But broken in spirit
• Health failing

Death (December 10, 1198)

Ibn Rushd died in Marrakesh, Morocco at age 72.

Circumstances:

• In political favor (partially restored)
• But philosophical legacy already destroyed in Islamic world
• Books had been burned
• Students scattered
• Philosophical school ended

Burial:

• Initially buried in Marrakesh
• Later, body transported back to Cordoba
• Buried in family cemetery

Contemporary Testimony:

Ibn al-Abbar (who witnessed the funeral procession) reported:

“His body was placed on one side of a beast of burden, with his writings on the other side to balance the load.”

Symbolic: The man balanced by his works.

Immediate Legacy:

In Islamic world:

• Philosophy in decline
• Ibn Rushd largely forgotten
• Few students continued his work

In Christian Europe (via translations):

• His commentaries just reaching universities
• Would become THE standard for 300 years
• Massive influence just beginning

The Irony:

He died obscure in his own civilization but was about to become one of the most influential philosophers in Christian Europe.

Part II: Major Works and Contributions

The Aristotle Commentaries: The Core Achievement

The Scope:

Ibn Rushd produced commentaries on virtually all of Aristotle’s works available in Arabic. This was unprecedented in scope and depth.

Three Levels of Commentary:

1. Short Commentaries (Jami):

• Summaries for students
• Essential points
• Introductory level
• Often omit technical details

2. Middle Commentaries (Talkhis):

• Paraphrase with explanation
• Most popular level
• Combined Aristotle’s text with Ibn Rushd’s clarification
• Independent treatises

3. Long Commentaries (Tafsir):

• Line-by-line analysis
• Technical, detailed
• Ibn Rushd’s own philosophical positions
• For advanced scholars
• Most influential in Latin West

Why This Mattered:

Problems Ibn Rushd Solved:

1. Aristotle’s Arabic translations were difficult: Often unclear, sometimes inaccurate
2. Previous commentaries mixed Aristotle with Neoplatonism: Ibn Sina had fused Aristotle with Plotinus—Ibn Rushd separated them
3. No systematic exposition existed: Needed comprehensive guide
4. Technical terminology inconsistent: Ibn Rushd standardized

Ibn Rushd’s Method:

• Textual analysis (philology)
• Historical context (what Aristotle actually meant)
• Philosophical arguments
• Refutation of misinterpretations (especially Ibn Sina’s)
• Independent judgment where Aristotle was wrong

The Achievement:

For 300+ years (1200-1500s), when European scholars studied Aristotle, they studied through Ibn Rushd’s eyes.

Major Commentaries:

1. Commentary on Aristotle’s Metaphysics

Ibn Rushd’s Interpretation:

Against Ibn Sina:

Ibn Sina had interpreted Aristotle through Neoplatonic emanation. Ibn Rushd argued:

• Aristotle didn’t teach emanation
• Ibn Sina mixed Aristotle with Plotinus
• Return to authentic Aristotle

Key Doctrines:

On Being:

• Being is not univocal (said in one sense)
• Being is said in multiple related senses (analogy)
• Substance is primary being
• Accidents depend on substance

On God:

• God is pure actuality
• Unmoved Mover
• Thinks only itself (thought thinking thought)
• Doesn’t know particulars directly (controversial)
• Eternal, necessary, incorporeal

On Matter and Form:

• All physical things are matter-form composites
• Matter is pure potentiality
• Form gives actuality
• Substantial forms vs. accidental forms

2. Commentary on De Anima (On the Soul)

Most Controversial Work:

His interpretation of Aristotle’s theory of the intellect sparked the “Averroist controversy.”

The Problem:

Aristotle’s De Anima contains obscure passages about the intellect:

• Passive intellect (potential)
• Active intellect (actual)
• Their relationship unclear

Ibn Rushd’s Interpretation (Simplified):

The Material Intellect:

• In individual humans
• Potential for thought
• Receives intelligible forms

The Active Intellect:

• Separate, eternal substance
• NOT part of individual human soul
• Shared by all humans
• Makes things actually intelligible

The Implication (Controversial):

If the active intellect is ONE and shared:

• Individual intellects are mortal
• Only the universal intellect is immortal
• Personal immortality is impossible
• After death, individual consciousness ceases

Ibn Rushd’s Actual Position (Debated):

Whether Ibn Rushd personally believed this or was just interpreting Aristotle remains debated. Some evidence suggests:

• He distinguished Aristotle’s view from Islamic doctrine
• He affirmed Islamic teaching of personal immortality as believer
• But philosophically followed Aristotle’s logic

Why This Caused Controversy:

In Latin Christian Europe, this seemed to deny:

• Personal immortality
• Individual resurrection
• Personal judgment
• Christian soteriology

This sparked “Latin Averroism”—see below.

3. Commentary on Physics

On Natural Philosophy:

Key Points:

Against Occasionalism:

Islamic theologians (Ash’arites) taught:

• No real causation in nature
• God creates each event directly
• Natural “causes” are just habits/customs
• Fire doesn’t cause burning—God creates burning when fire touches

Ibn Rushd Argued:

• Nature has real causal powers
• Fire REALLY causes burning (naturally)
• God works through secondary causes
• Denying natural causation makes science impossible

On Motion:

• Motion is real change (against Parmenides)
• Requires potentiality in nature
• Four causes explain all motion
• Ultimate explanation: Prime Mover (God)

On Infinity:

• No actual infinite (only potential infinite)
• Universe is spatially finite
• But temporally eternal

4. Commentary on Nicomachean Ethics

Ethical Philosophy:

Key Teachings:

• Happiness (eudaimonia) is the highest good
• Virtue is mean between extremes
• Intellectual virtues superior to moral virtues
• Contemplative life is highest
• Practical wisdom guides action

Ibn Rushd’s Addition:

• Integrated with Islamic ethics
• Role of shari’ah in guiding virtue
• Prophetic law as pathway to excellence
• But philosophical life as highest

Original Philosophical Works

1. The Incoherence of the Incoherence (تهافت التهافت)

Context:

Al-Ghazali (1058-1111) had written The Incoherence of the Philosophers, attacking falsafa (philosophy). He declared three philosophical positions to be unbelief (kufr):

1. Eternity of the world (denies creation in time)
2. God’s ignorance of particulars (God knows only universals)
3. Denial of bodily resurrection (only spiritual resurrection)

Al-Ghazali argued philosophy contradicts Islam and should be abandoned.

Ibn Rushd’s Response (Written ~1180, 69 years after al-Ghazali’s death):

Ibn Rushd wrote point-by-point refutation defending:

• Philosophy’s legitimacy
• Compatibility with Islam
• Al-Ghazali’s misunderstandings

Structure:

Follows al-Ghazali’s text, responding to each argument.

Key Arguments:

On Eternity of World:

Al-Ghazali: Universe must have beginning (Islamic doctrine).

Ibn Rushd:

• Aristotle proved universe eternal
• But “eternal” doesn’t mean “uncreated”
• God eternally creates/sustains universe
• No temporal beginning but ontologically dependent
• Different from atheist eternity

On Causation:

Al-Ghazali: No necessary causation—God creates each event.

Ibn Rushd:

• Denying causation contradicts Quran (which describes natural laws)
• Makes science impossible
• Confuses God’s power with actual creation
• God creates THROUGH secondary causes

On God’s Knowledge:

Al-Ghazali: God knows every particular thing/event.

Ibn Rushd:

• God knows universals perfectly
• Knows particulars through knowing universal causes
• Different kind of knowledge than human knowledge
• Not ignorance—superior knowledge

Philosophical Importance:

This work:

• Last great defense of philosophy in Islamic philosophy
• Sophisticated philosophical arguments
• But failed to revive philosophical tradition in Islamic world
• Succeeded in Latin Europe (translated, studied widely)

2. Fasl al-Maqal (The Decisive Treatise)

Full Title: Fasl al-Maqal fi ma bayna al-Hikmah wa al-Shari’ah min al-Ittisal (The Decisive Treatise on the Connection Between Religion and Philosophy)

Central Question:

Does Islamic law permit, forbid, or require the study of philosophy?

Ibn Rushd’s Answer:

Islamic law requires philosophical study (for those capable).

The Argument:

1. Quranic Mandate:

“Reflect, you who have vision” (Quran 59:2) “Have they not contemplated the kingdom of heaven and earth?” (Quran 7:185)

The Quran commands rational reflection on creation.

2. Philosophy is Reflection:

Philosophy = systematic rational reflection on existence.

Therefore: Quran commands philosophy (for the intellectually capable).

3. No Real Conflict:

Truth cannot contradict truth.

• Philosophy reaches truth through reason
• Religion reveals truth through scripture
• Both from God
• Apparent conflicts = misunderstanding

4. Levels of Understanding:

Ibn Rushd distinguishes three classes of people:

Demonstrative (Philosophers):

• Understand through proof and logic
• Should interpret scripture philosophically when needed
• Rare—small elite

Dialectical (Theologians):

• Understand through probable arguments
• Use kalam (theology)
• Educated class

Rhetorical (Masses):

• Understand through persuasion and imagery
• Accept literal meanings
• Majority of people

Crucial Point:

Each group should receive teaching appropriate to their level:

• Don’t give philosophical interpretations to masses (confuses them)
• Don’t give literal readings to philosophers (beneath their capacity)
• Different levels of truth for different capacities

Controversial Implication (Double Truth?):

This seemed to suggest:

• Philosophical truth might differ from religious truth
• What’s true philosophically might be false religiously (and vice versa)

Did Ibn Rushd Teach “Double Truth”?

The Charge:

Latin Averroists were accused of holding:

• Something can be true in philosophy but false in theology
• Two contradictory truths can coexist

Ibn Rushd’s Actual View (Debated):

Most scholars today argue:

• He believed in ONE truth
• But multiple valid expressions of that truth
• Philosophical and scriptural expressions of same reality
• Different forms appropriate to different audiences

Not double truth but:

• Multiple valid interpretations
• Hierarchy of understanding
• Esoteric vs. exoteric knowledge

3. Medical Encyclopedia: Kitab al-Kulliyat (The Generalities)

Latin Title: Colliget

Nature:

Systematic medical encyclopedia covering:

• Anatomy
• Physiology
• Pathology
• Therapeutics
• Hygiene
• Pharmacology

Relationship to Ibn Sina’s Canon:

• Ibn Sina: Clinical focus, particulars, specific diseases/treatments
• Ibn Rushd: Theoretical focus, universals, general principles

Designed to complement each other:

• Ibn Sina: Particularia (particulars)
• Ibn Rushd: Universalia (universals)

Contribution:

• Systematic theoretical framework
• Philosophical rigor applied to medicine
• Less influential than Canon but respected
• Used at some European universities

4. Legal Work: Bidayat al-Mujtahid

Full Title: Bidayat al-Mujtahid wa Nihayat al-Muqtasid (The Distinguished Jurist’s Primer and the Layman’s Objective)

Nature:

Comparative Islamic jurisprudence:

• Surveys all major legal schools
• Compares their positions on each issue
• Analyzes evidence for each position
• Independent reasoning (ijtihad)

Structure:

Organized by topics:

• Worship (ibadat)
• Transactions (mu’amalat)
• Family law
• Criminal law
• etc.

Methodology:

For each legal question:

1. What do different schools say?
2. What is their evidence?
3. Whose reasoning is stronger?
4. Independent conclusion

Importance:

• Still used in Islamic legal studies
• Model of comparative jurisprudence
• Shows Ibn Rushd’s mastery of Islamic law
• Demonstrates he was jurist first, philosopher second

Part III: Core Philosophical Positions

1. The Harmony of Reason and Revelation

Central Conviction:

Philosophy (reason) and religion (revelation) cannot ultimately conflict because both come from God.

The Principle:

If apparent conflict exists:

1. Check if philosophical reasoning is valid
2. Check if scriptural interpretation is correct
3. One or both must be wrong
4. Truth is single—contradictions are impossible

Implications:

When Scripture Seems to Contradict Philosophy:

• Scripture may be speaking metaphorically
• Philosophical interpretation is legitimate
• Different levels of meaning
• Literal sense for masses, philosophical sense for elite

Examples:

God’s “Hand”:

• Literal: God has physical hand (anthropomorphism)
• Philosophical: God’s power/action (metaphorical)

Creation “in six days”:

• Literal: Temporal process
• Philosophical: Stages of logical dependence (not temporal)

The Throne:

• Literal: Physical throne in sky
• Philosophical: Symbol of God’s sovereignty

The Method:

Use ta’wil (allegorical interpretation) when necessary:

• Not arbitrary interpretation
• Based on principles
• Reserved for trained philosophers
• Not shared with masses (would confuse them)

2. Against Ibn Sina’s Neoplatonism

Ibn Rushd’s Criticism:

Ibn Sina mixed Aristotle with Neoplatonism (Plotinus), creating hybrid philosophy that:

• Distorted Aristotle
• Added unnecessary metaphysics
• Made philosophy vulnerable to theological attack

Specific Disagreements:

Emanation:

Ibn Sina: Universe emanates from God in necessary sequence (First Intelligence, Second Intelligence, etc.).

Ibn Rushd: This is Plotinus, not Aristotle. Aristotle’s God is Final Cause (attracts universe through love), not Efficient Cause (produces universe through emanation).

Essence-Existence Distinction:

Ibn Sina: Real distinction between essence and existence in created things.

Ibn Rushd: This is conceptual distinction only. In reality, essence and existence are identical in existing thing. Adding “existence” to essence is mistake.

Knowledge:

Ibn Sina: Human knowledge comes through illumination from Active Intellect.

Ibn Rushd: Knowledge comes through abstraction from sensory experience. No illumination needed.

Ibn Rushd’s Goal:

Return to authentic Aristotle—purge Neoplatonic additions.

3. Theory of the Intellect (The Controversy)

The Problem:

What happens to human intellect after death?

Ibn Rushd’s Interpretation of Aristotle:

Three Intellects:

1. Material Intellect:

• Potential for thought in individual human
• Receives intelligible forms
• Like wax ready to receive seal

2. Active Intellect:

• Separate, eternal substance
• Makes potentially intelligible actually intelligible
• Like light making potentially visible actually visible
• Shared by all humans (not individual)

3. Acquired Intellect:

• Conjunction of material and active intellects
• Actual thinking
• Temporary state during life

The Controversial Claim:

The Active Intellect is:

• ONE (not many)
• Eternal
• Separate from individuals
• Shared by all humanity

Therefore:

• Individual material intellects are mortal
• When body dies, individual intellect perishes
• Only universal Active Intellect continues
• Personal immortality impossible (philosophically)

But Ibn Rushd Also Said:

• Islamic teaching of personal immortality is true
• Religion teaches truths philosophy cannot demonstrate
• Faith supplements philosophy

The Problem:

How can both be true?

• Philosophy: No personal immortality
• Islam: Personal immortality certain

Ibn Rushd’s Answer (Probably):

Different levels of truth for different audiences:

• Philosophical demonstration reaches certain limits
• Religious revelation goes beyond
• Not contradiction but complement

Latin Europe’s Interpretation:

Latin Averroists took this as “double truth”:

• True in philosophy, false in theology
• This caused major controversy

4. Eternity of the World

The Question:

Did universe have temporal beginning or is it eternal?

Ibn Rushd’s Position:

Universe is eternal (no temporal beginning) but created/caused by God.

The Argument:

1. Creation Requires Time:

If God created universe at moment T:

• Before T, why didn’t God create?
• What changed to make God create at T rather than earlier?
• If God’s will changed, God is imperfect (change implies potentiality)
• If God’s will was always to create at T, this is arbitrary

2. Time Itself Requires Universe:

• Time is measure of motion (Aristotle)
• No motion without physical universe
• Therefore no time before universe
• “Before universe” is meaningless
• Universe must always have existed

3. God Is Eternal and Perfect:

• God’s perfection doesn’t change
• God’s creative power doesn’t begin at some point
• Therefore God’s creation is eternal

Not Atheistic:

This is NOT saying universe is self-sufficient:

• Universe still depends on God ontologically
• God is still First Cause
• God eternally sustains universe in being
• Creation is ontological dependence, not temporal beginning

The Distinction:

Temporal Creation: Universe began at time T (Islamic theology)

Eternal Creation: Universe always existed but always dependent on God (Aristotle/Ibn Rushd)

Ibn Rushd’s Compromise:

• Philosophically: Universe eternal
• Religiously: Quranic teaching of temporal creation true for masses
• Different expressions of relationship between God and world

5. Causation and Natural Law

Against Occasionalism:

Ash’arite theologians (dominant in Islam) taught:

• No real causation
• God creates each event directly
• Fire doesn’t cause burning—God creates burning when fire touches
• Natural “laws” are habits, not necessities

Why They Taught This:

• Preserve God’s omnipotence
• Prevent secondary causes competing with God
• Allow for miracles

Ibn Rushd’s Response:

This doctrine:

1. Makes science impossible (no reliable natural laws to study)
2. Contradicts Quran (which describes natural regularities)
3. Misunderstands God’s power (God works THROUGH natural causes)
4. Confuses power with actuality (God could violate laws but chooses not to)

Ibn Rushd’s Position:

• Nature has real causal powers (given by God)
• Natural laws are real and necessary
• God works through secondary causes
• Science studies God’s way of governing world
• Miracles possible but rare exceptions

Example:

Fire causes burning:

• This is REAL causation (not just habit)
• Fire has power to burn (from God)
• Burning follows necessarily from fire’s nature
• God could prevent it (miracle) but normally doesn’t

Importance:

This defense of natural causation was crucial for:

• Scientific inquiry
• Philosophy of nature
• Understanding God’s relationship to world

6. Political Philosophy

Limited Work:

Unlike al-Farabi or Ibn Sina, Ibn Rushd wrote less on politics. But:

Commentary on Plato’s Republic:

(Aristotle’s Politics was not available in Arabic, so Ibn Rushd commented on Plato’s Republic instead)

Key Ideas:

Philosopher-Ruler:

• Best government is philosopher-king
• Wisdom should govern
• Most states fall short of ideal

Role of Religion:

• Religion is civil glue
• Provides social cohesion
• Communicates philosophical truths to masses
• Prophet is philosopher-lawgiver

Islamic Context:

• Shari’ah (Islamic law) embodies philosophical wisdom in religious form
• Prophet Muhammad was philosopher-king
• Islamic state approaches Platonic ideal (when well-governed)

Classes:

Like Plato:

• Rulers (philosophers)
• Guardians (military)
• Producers (workers)

Women can be guardians and even rulers (following Plato—radical for medieval world).

Part IV: The Two Legacies

Legacy in the Islamic World: Decline and Forgetting

Why Ibn Rushd Was Forgotten:

1. Geographic Periphery:

• He lived in Muslim Spain/Morocco (western edge)
• Far from Baghdad, Cairo (intellectual centers)
• His works didn’t circulate widely in Arabic

2. Al-Ghazali’s Victory:

• Al-Ghazali’s critique of philosophy became orthodox
• Philosophy increasingly seen as dangerous
• Religious scholars (ulama) hostile to falsafa
• Safer to study theology than philosophy

3. Political Context:

• Almohad persecution of philosophy
• Books burned
• Students scattered
• No institutional support

4. Mongol Invasions (1258):

• Baghdad destroyed
• Libraries burned
• Intellectual centers devastated
• Philosophy in crisis everywhere

5. Shift Toward Mysticism:

• Sufism became dominant spiritual path
• Less emphasis on rationalism
• Mystical experience over philosophical proof

6. Ibn Sina’s Dominance:

• Where philosophy survived (Shia world, Iran), Ibn Sina was standard
• Ibn Rushd’s critique of Ibn Sina rejected
• Neoplatonic tradition continued

Result:

• Few Arabic manuscripts preserved
• Not taught in madrasas
• Forgotten by 1300
• Remembered as jurist, not philosopher
• Bidayat al-Mujtahid (legal work) survived; commentaries largely lost in Arabic

Modern Islamic World:

20th-century revival:

• Rediscovered through European sources
• Translations back to Arabic from Latin/Hebrew
• Symbol of Islamic rationalism
• Used in debates about reason and faith
• But still not central to Islamic philosophy

Legacy in Latin Christian Europe: The Commentator

How Ibn Rushd Reached Europe:

Translation Movement (12th-13th centuries):

Christian scholars in Spain translated Arabic works:

• Michael Scot (1217-1235): Translated many commentaries
• Hermann the German: Translated more
• Others: Continued through 13th century

What Was Translated:

• Most of his Aristotle commentaries (long and middle versions)
• The Incoherence of the Incoherence
• Some medical works
• Others

Language Path:

Arabic → Latin (sometimes via Hebrew intermediary)

Impact:

1. The Standard Aristotle:

For 300+ years (1200-1500s):

• When Europeans studied Aristotle, they used Ibn Rushd’s commentaries
• “Aristotle said… but The Commentator explains…”
• Ibn Rushd was THE authoritative interpreter

2. University Curriculum:

Required reading at:

• University of Paris
• Oxford
• Padua
• Bologna
• Others

Philosophy curriculum = Aristotle through Ibn Rushd.

3. Major Thinkers Influenced:

Albertus Magnus (1200-1280):

• Knew Ibn Rushd extensively
• Often agreed with him
• Sometimes disagreed

Thomas Aquinas (1225-1274):

• Cited Ibn Rushd hundreds of times
• Sometimes agreed (“The Commentator says well…”)
• Often disagreed (especially on intellect)
• Engaged deeply with Ibn Rushd’s arguments

Dante Alighieri (1265-1321):

• Placed Ibn Rushd in Limbo (Divine Comedy, Inferno IV)
• Among virtuous pagans and non-Christian philosophers
• With Aristotle, Socrates, Plato, Cicero, Seneca
• High honor for non-Christian

John Duns Scotus (1266-1308):

• Engaged with Ibn Rushd’s metaphysics
• Disagreed on univocity of being

The “Latin Averroist” Controversy

What Was “Latin Averroism”?

A movement at University of Paris (1250-1277) associated with interpreting Aristotle through Ibn Rushd.

Key Figures:

• Siger of Brabant (1240-1284)
• Boethius of Dacia (fl. 1270s)

Controversial Doctrines:

Following Ibn Rushd’s interpretations:

1. Unity of the Intellect:
   • Only one Active Intellect for all humans
   • Individual intellects are mortal
   • No personal immortality
2. Eternity of the World:
   • Universe has no temporal beginning
   • Always existed
3. Determinism:
   • Celestial spheres determine earthly events
   • Limited human free will

The “Double Truth” Charge:

Averroists were accused of holding:

• Something can be true in philosophy but false in theology
• “According to philosophy, the soul is mortal; according to faith, it’s immortal”

Did They Actually Hold This?

Debated. They may have meant:

• Philosophy reaches certain conclusions
• Faith teaches different truths
• Not that both are true, but that philosophy has limits

The Condemnation of 1277:

Bishop Étienne Tempier condemned 219 propositions, including:

• Unity of the intellect
• Eternity of the world
• Determinism
• Limitations on God’s power
• Many specifically targeting “Averroist” interpretations

Effect:

• “Averroism” became dangerous
• Scholars distanced themselves
• More careful reading required
• But Ibn Rushd’s commentaries continued to be studied

Thomas Aquinas’s Position:

• Used Ibn Rushd’s commentaries extensively
• Agreed on many points (natural causation, etc.)
• Strongly disagreed on intellect (defended personal immortality)
• Wrote De Unitate Intellectus Contra Averroistas (On the Unity of the Intellect, Against the Averroists)

Renaissance and Decline

Italian Renaissance (1400s-1500s):

Peak of Averroist Influence:

University of Padua became center of “Averroist” thought:

• Medical school emphasized philosophy
• Aristotelian naturalism
• Ibn Rushd standard authority

Major Figures:

• Pietro Pomponazzi (1462-1525): Defended mortality of soul on philosophical grounds
• Others: Continued tradition

Debates:

• Immortality of soul
• Relationship of philosophy and theology
• Nature of intellect

The Decline:

Factors:

1. Reformation (1517+): New theological priorities
2. Counter-Reformation: Catholic Church reasserted control
3. Scientific Revolution: New methods and authorities
4. Humanism: Direct reading of Greek texts (bypassing Arabic intermediaries)
5. Descartes and Modern Philosophy: New frameworks replaced Aristotelian

By 1650:

• Ibn Rushd no longer required reading
• Aristotelian philosophy in decline
• Modern science and philosophy emerging
• Historical curiosity, not living tradition

Modern Rediscovery

19th-20th Centuries:

Academic Study:

• Ernest Renan: Averroès et l’Averroïsme (1852)
• Critical editions published
• Historical studies of medieval philosophy
• Arabic texts rediscovered (some only in Latin/Hebrew)

Islamic World:

• 20th-century Arab intellectuals rediscovered
• Symbol of Islamic rationalism
• Used in modernization debates
• Secular thinkers claimed him
• Religious thinkers reinterpreted him

Contemporary Status:

In Academia:

• Medieval philosophy specialty
• History of Aristotelian commentary
• Islamic philosophy
• Comparative philosophy

In Islamic Discourse:

• Contested figure
• Secularists celebrate him
• Traditionalists suspicious
• Modernists invoke him

Not in Popular Culture:

• Unlike Rumi, Ibn Rushd unknown to general public
• Technical philosopher, not poet
• No popularization movement

Part V: Common Misunderstandings

Misunderstanding 1: Ibn Rushd Taught “Double Truth”

The Myth:

Ibn Rushd believed something could be simultaneously true in philosophy and false in theology (double truth doctrine).

The Reality:

What He Actually Taught:

Truth is single and unified. But:

1. Different people understand truth differently (philosophical vs. rhetorical)
2. Same truth can be expressed philosophically or religiously
3. When apparent conflict exists, reinterpret scripture allegorically
4. Different levels of meaning for different capacities

NOT Double Truth:

He didn’t say: “The soul is mortal (philosophy) AND immortal (theology)—both true.”

He said: “Philosophy demonstrates one thing; religious teaching says another; both are expressions of single truth; when conflict arises, philosophical interpretation of scripture resolves it.”

Where Confusion Came From:

Latin Averroists at Paris (1260s-1270s) were ACCUSED of double truth. Some may have held problematic positions. But this was distortion of Ibn Rushd’s actual view.

Misunderstanding 2: Ibn Rushd Was Secular or Anti-Religious

The Myth:

Because he defended philosophy and critiqued theologians, some portray him as secular rationalist or closet atheist.

The Reality:

Ibn Rushd was:

• Devout Muslim (prayed five times daily)
• Expert in Islamic law (qadi for decades)
• Wrote major work of jurisprudence
• Defended compatibility of faith and reason
• Believed revelation was necessary and true
• Studied and taught Quran

His Project:

NOT to replace religion with philosophy, but to show they’re compatible.

His Conviction:

• Philosophy strengthens faith
• Reason confirms revelation
• Apparent conflicts are misunderstandings
• Both reason and faith from God

Misunderstanding 3: Ibn Rushd Rejected Ibn Sina

The Confusion:

Ibn Rushd criticized Ibn Sina extensively, so he must have rejected him entirely.

The Reality:

What He Criticized:

• Ibn Sina’s Neoplatonic additions to Aristotle
• Emanation cosmology
• Essence-existence distinction (as real)
• Illumination theory of knowledge

What He Respected:

• Ibn Sina’s medical work (massive respect)
• His logical acumen
• His influence and importance
• His systematizing genius

The Goal:

Not to destroy Ibn Sina but to:

• Return to purer Aristotle
• Remove Neoplatonic accretions
• Defend philosophy against al-Ghazali more effectively

They Weren’t Enemies:

This was philosophical debate between scholars who never met (Ibn Sina died when Ibn Rushd was born). Ibn Rushd’s critique was respectful scholarly disagreement.

Misunderstanding 4: Ibn Rushd Was More Influential Than Ibn Sina

In Christian Europe: TRUE

Ibn Rushd was “The Commentator”—supreme authority.

In Islamic World: FALSE

• Ibn Sina remained THE philosopher
• Studied in Iran, India, throughout East
• Ibn Rushd largely forgotten
• Even today, Ibn Sina more influential in Islamic philosophy

Why This Matters:

Eurocentric history emphasizes Ibn Rushd (because important to Europe). But from Islamic perspective, Ibn Sina’s influence dwarfs Ibn Rushd’s.

Different Trajectories:

• Ibn Sina: Massive impact in Islamic world, moderate in Europe
• Ibn Rushd: Minimal impact in Islamic world, massive in Europe

Misunderstanding 5: The Condemnation of 1277 Ended His Influence

What Happened:

Bishop Tempier condemned 219 propositions at Paris in 1277, many associated with “Averroism.”

The Myth:

This ended Ibn Rushd’s influence in Europe.

The Reality:

• His commentaries continued to be studied
• Required at major universities
• Influence peaked 1300-1500 (AFTER condemnation)
• University of Padua became Averroist center in Renaissance
• Lasted until 1600s

The condemnation made certain doctrines dangerous but didn’t end study of his works.

Part VI: Key Passages and Arguments

Passage 1: On the Necessity of Philosophy (from Fasl al-Maqal)

Ibn Rushd’s Argument:

“If the activity of philosophy is nothing more than study of existing beings and reflection on them as indications of the Artisan, i.e., inasmuch as they are products of an art (for beings only indicate the Artisan through our knowledge of the art in them, and the more perfect this knowledge is, the more perfect is the knowledge of the Artisan), and if the Law has encouraged and urged reflection on beings, then it is clear that what this name signifies [philosophy] is either obligatory or recommended by the Law.

That the Law summons to reflection on beings and urges it is clear from several Quranic verses, such as: ‘Reflect, you who have vision’ (59:2); ‘Have they not contemplated the kingdom of heaven and earth?’ (7:185); ‘Do they not reflect upon the camels, how they are created?’ (88:17).

Since it has now been established that the Law has rendered obligatory the study of beings by the intellect and reflection on them, and reflection is nothing more than inference and drawing out of the unknown from the known, and this is reasoning or a part of reasoning, therefore we are under an obligation to carry on our study of beings by intellectual reasoning.”

Analysis:

This is Ibn Rushd’s core argument for philosophy’s religious legitimacy:

1. Quran commands rational reflection on creation
2. Philosophy IS systematic rational reflection
3. Therefore: Quran commands philosophy
4. For those capable of it, philosophy is religious duty

Significance:

Defends philosophy using Islamic sources themselves—not external Greek authority but Quranic mandate.

Passage 2: On Levels of Understanding (from Fasl al-Maqal)

Ibn Rushd Explains:

“People in relation to the Law are of three sorts:

One sort is those who are not people of interpretation at all; these are the rhetorical class, and they are the overwhelming mass, for no person of sound intellect is exempted from this kind of assent.

Another sort is those who are people of dialectical interpretation; these are the dialecticians, either by nature alone or by nature and habit.

Another sort is those who are people of certain interpretation; these are the demonstrative class, by nature and training—that is, in the art of philosophy. This interpretation ought not to be expressed to the dialectical class, let alone to the masses.”

The Hierarchy:

1. Rhetorical (Masses):

• Understand through imagery, metaphor, emotion
• Accept literal meanings
• Majority of people
• Don’t need/can’t handle philosophical interpretation

2. Dialectical (Theologians):

• Understand through probable arguments
• Engage in theological debate (kalam)
• Educated class
• Can handle some interpretation but not full philosophy

3. Demonstrative (Philosophers):

• Understand through logical proof
• Require certainty
• Small elite
• Can and should interpret scripture philosophically

The Principle:

Give each group teaching appropriate to their level. Don’t confuse masses with philosophy; don’t restrict philosophers to literal meanings.

Controversial Implication:

Suggests esoteric knowledge (philosophy) vs. exoteric knowledge (literal religion)—which some saw as elitism or duplicity.

Passage 3: Against al-Ghazali on Causation (from Tahafut al-Tahafut)

Al-Ghazali’s Position:

Fire doesn’t cause burning. God creates burning when fire touches cotton. No necessary causal connection.

Ibn Rushd’s Response:

“To deny the existence of efficient causes which are observed in sensible things is absurd. One who denies this can no longer acknowledge that from every act there must arise an act… The theologians who deny causation claim that God creates the burning in the cotton when fire touches it, not that the fire causes it.

But this is sophistry. For he who denies this must deny that the action has an agent, and must say that it is possible that a man may write without a hand, or see without eyes… If we have no assent to the causes which exist in the act of seeing and writing, how can we assert that all acts proceed from God?

Further, if we do not acknowledge causes in the visible world, how can we know invisible causes? All our knowledge of the invisible is founded on the visible… If causation is denied, proof of God’s existence becomes impossible.”

Ibn Rushd’s Argument:

1. We observe constant conjunction: Fire + cotton → burning
2. This is not mere habit but natural necessity
3. Denying this makes all knowledge impossible
4. Can’t prove God exists if we deny causal inference
5. God works THROUGH natural causes, not despite them

Significance:

Defense of natural law and scientific inquiry against theological occasionalism.

Passage 4: On the Unity of the Intellect (from Long Commentary on De Anima)

The Controversial Passage:

“The material intellect is one in all men… For the forms which exist in the material intellect are neither multiple nor one—not multiple through the multiplicity of recipients, for the recipient is one; nor one through unity of form, for it receives all forms.

The Active Intellect is also one… Therefore when individual human beings cease to exist, the intellect remains, both the material and the active.”

The Implication:

Individual human intellects are mortal; only universal Intellect continues.

But Ibn Rushd Also Wrote:

“What the religious teaching says about resurrection and the afterlife cannot be demonstrated philosophically, but must be accepted on faith. The religious teaching is true.”

The Tension:

How can both be true?

Possible Interpretations:

1. Double Truth (accused position): Both true in different domains
2. Philosophy’s Limits: Philosophy reaches certain conclusions, but faith goes beyond
3. Different Meanings: “Immortality” means different things philosophically vs. religiously
4. Exoteric vs. Esoteric: Different truths for different audiences

What Ibn Rushd Probably Meant:

Philosophy demonstrates what it can; religious teaching reveals what philosophy cannot reach; both are true in their domains; not contradiction but complementarity.

Conclusion: The Two Worlds of Ibn Rushd

Abu al-Walid Muhammad ibn Ahmad ibn Rushd died 826 years ago. His legacy split into two divergent streams:

In the Islamic World:

A brilliant jurist whose philosophical work was largely forgotten:

• His legal text survived and is studied
• His philosophy declined with falsafa generally
• Remembered more as judge than philosopher
• 20th century rediscovery as symbol of rationalism
• Contested figure in modern Islamic thought

In Latin Christian Europe:

“The Commentator”—supreme authority on Aristotle:

• Required reading for 400 years
• Shaped entire philosophical tradition
• Influenced every major scholastic thinker
• Sparked controversies that defined medieval thought
• Eventually superseded by modern philosophy

The Paradox:

Most influential where he was foreign (Christian Europe). Largely forgotten where he was home (Islamic world).

Why He Matters:

1. The Last Great Defense:

Ibn Rushd was the last major Islamic philosopher to defend falsafa against theological attacks. After him, philosophy declined in Sunni Islamic world (continued in Shia Iran, but through Ibn Sina, not Ibn Rushd).

2. The Bridge:

He transmitted Aristotle to Christian Europe at a crucial moment. Without his commentaries, medieval European philosophy would have looked very different.

3. The Questions:

He forced medieval thinkers to grapple with:

• Relationship between reason and revelation
• Personal immortality
• Nature of the intellect
• Eternity of the world
• Natural causation
• Limits of philosophical demonstration

4. The Method:

His careful textual analysis, philosophical rigor, and systematic approach influenced how later generations read philosophical texts.

The Ultimate Question He Poses:

Can reason and revelation coexist? His answer: yes, necessarily, because truth is one and God is source of both.

His Life’s Achievement:

Despite political upheaval, persecution, and the burning of his books, Ibn Rushd produced:

• Comprehensive commentaries on Aristotle
• Original philosophical works
• Major medical encyclopedia
• Authoritative legal treatise
• Bridge between civilizations

Final Assessment:

Ibn Rushd represents the culmination of classical Islamic philosophy. He attempted to synthesize Greek wisdom with Islamic revelation, to demonstrate their compatibility, to show that faith and reason together reach truth more fully than either alone.

In his own civilization, this project was rejected. In Christian Europe, it was embraced, debated, and eventually superseded. But the questions he raised remain vital: How do we integrate different sources of knowledge? What are the limits of reason? How do we read authoritative texts? What is the relationship between philosophy and faith?

These questions echo still.
