Abu Yusuf Yaqub al-Mansur

Yaqub al-Mansur ruled the Almohad Caliphate in North Africa and part of the Iberian Peninsula from 1184 until his death on 23 January 1199. During that time he managed to hold off attempts by the Christian rulers of Iberia to reclaim lands controlled by Muslims.

It was his father, Abu Yaqub Yusuf (reigned 1163 - 1184) who originally spread the caliphate to Iberia in 1170. Not content to hold Seville and surrounding territory, he marched an army to Portugal. He was countered by Afonso I of Portugal and Ferdinand II of León. Wounded by a crossbow, he died on 29 July.

His son vowed revenge, taking several castles and handing out defeats to Christians before returning to Africa. When Alfonso VIII of Castile mounted a reconquista, al-Mansur returned and defeated the Christians again, this time taking hundreds as slaves and selling them in Africa.

Besides being a successful military commander, he was also a patron of the arts and architecture. He added a massive gate to the Kasbah, a major citadel in Morocco (seen above), and finished a mosque in Marrakesh. He also began what would have been the largest mosque in the world, but construction was discontinued after 1199, leaving only a massive minaret. One of his other accomplishments was the first hospital in Morocco.

The philosopher Averroes was a favorite of al-Mansur's and had a place at his court, even though some of his ideas got him in trouble for being too radical and anti-Muslim. al-Mansur was well-read and well-versed in Islam, and even wrote a book on the prophet Muhammad. His father had appointed a chief judge who made sure the law adhered to strict interpretation of the Koran. al-Mansur took this a step further and had that judge destroy any books of law that did not conform.

The mosque whose construction he finished was the Kutubiyya Mosque. Kutubiyya and several other mosques were redone by the Almohads. Not because they were not beautiful enough, or large enough, but because they were built "wrong." I'll explain the qibla tomorrow.

The Almohads in Iberia

The Almohads were a North African Berber group who founded an empire in the 12th century. By 1159 they had extended their power over the Maghreb (northwest Africa). By 1172, the Muslim parts of the Iberian Peninsula (south and east) were under their rule, taking over from the Almoravid dynasty.

Two of the rulers of the Almohads were Abu Yaqub Yusuf, who ruled from 1163 to 1184, and his son, Abu Yusuf Yaqub al-Mansur ("the Victorius"), who ruled from 1184 until 1199). Under their strict Muslim rule, many Christians and Jews migrated to the Christian nations of Aragon, Castile, and Portugal.

In 1195, when al-Mansur was in Africa, Alfonso VIII of Castile decided to mount a reconquista and reclaim the Muslim-controlled lands in Iberia. He united the kingdoms of Aragon, Castile, León, Portugal, and Navarre. When al-Mansur heard of their advance into his territory, he quickly returned from Africa. His major defeat of the Christian army at the Battle of Alarcos was when he took on the epithet "al-Mansur."

In 1212, Pope Innocent III initiated a Crusade against the Muslims in Iberia. Alfonso and his Castilians, Peter II of Aragon, Sancho VII of Navarre (who earlier had helped defend the continental interests of his brother-in-law, Richard Lionheart), and Franks under the vicious Archbishop Arnaud Amalric, united at the pope's request. Their final battle against the forces of the leader Muhammad al-Nasir broke the hold of the Almohad Caliphate in Iberia.

The Almohads were still strong in North Africa, but eventually they were supplanted by the growing Berber Marinid Sultanate.

Although fierce when it came to protecting his territory and religion, al-Mansur softened over time, and although the Koran was the only allowed source of law, he allowed philosophers to theorize without punishment. Averroes' radical statements made him despised by some, but al-Mansur kept him safe at court. al-Mansur was a complex individual who supported the arts and architecture and, well, let's take a closer look at him tomorrow.

Scholasticism

Around 1100CE, monastic schools started to discover the works of Aristotle, thanks to Judea-Islamic translations. Just as scholarly study was taking off in Western Europe, suddenly a body of knowledge that included a system of logic and was accompanied by a name of tremendous reputation. (One wonders what might have developed on its own if Aristotle hadn't appeared to offer them a "mold" to fit.)

Now scholars had a framework for studying the world, and by that I mean God. After all, among all the potential different opinions and ideas philosophers might have had, there was one constant: a supreme Being existed whose existence explained all things. Philosophers/Theologians from the Christian and Jewish and Muslim traditions—all children of Abraham—all agreed that everything came from God, and here now was the most prestigious pagan thinker "agreeing" with his logical conclusion that everything came from the Unmoved Mover, the First Cause.

But questions—and disagreements—remained.

Maimonides felt that philosophy/logic and religion were not opposing modes of thought; they should both lead to the same truths. You remember from several posts ago that he considered it appropriate to describe God in terms of what He was not. "God is not non-existent"; "God is not ignorant"; et cetera. This method is called apophatic. He also said "God is not corporeal" because to describe God—who was of course to be worshipped—as having a body would be a step toward idolatry, to which Maimonides was opposed. This got him into hot water with those scholars who took Genesis 1:26 seriously: "Let is make man in our image." He was condemned, and some wanted him excommunicated.

Averroes came under fire because he also considered philosophy an alternate but equal-to-religion way of finding truth that cannot contradict revelations in Islam. He believed that any contradictions should be resolved by understanding that the revelations in Islam about God must have been interpreted wrongly, and would need to be re-examined using philosophy. This flew in the face of fundamentalism; critiques of philosophy like The Incoherence of the Philosophers denounced people like Averroes. In 1195 his teachings were condemned, his works were ordered burned, and he was banished (although he was returned to court shortly before he died, on 11 December 1198).

Aquinas caused raised eyebrows because of Aristotle and Averroes. Introducing their ideas from non-Christian sources was a very controversial move. When Aquinas was made regent master at the University of Paris, he was accused of encouraging Averroists by a Franciscan master who considered certain more free-thinking philosophers as "blind leaders of the blind."

So philosophers and theologians who centuries later are heralded as giants in the field whose works are considered foundational were not universally respected or followed in their own time.

A little more on Scholasticism next time, and then maybe time for a lighter topic or two.

Averroes

(Note: Most of this is from the previous post "The Commentator" on 11 December 2012)

Averroes (1126-1198) was born in Córdoba into a family of distinguished jurists and scholars at a time when Islamic culture was flourishing in Spain. He probably would have spent his life as a judge if not for his mentor and friend, the physician Abu Bakr ibn Tufayl, who told him that he should write commentaries on the works of Aristotle. The problem seen by ibn Tufayl was that Aristotle was too obscure either because of the ambiguity of his own writing or the shortcomings of his translators.

Averroes, whose real name was ʾAbū al-Walīd Muḥammad bin ʾAḥmad bin Rušd, embraced the task so thoroughly that, to the West, he became known as "The Commentator." His scholarship was embraced across cultures: Jacob Anatoli translated Averroes' Commentaries into Hebrew. Anatoli's colleague and friend Michael Scot translated some directly into Latin.

He analyzed and promoted most of Aristotle (and Plato's Republic) to the known world, as well as writing dozens of books of his own. So far as we know, he did not have access to original texts—there is no evidence that he knew Greek—and so his commentaries are based on Arabic translations of Aristotle.

He was a rationalist, he asserted that philosophy and religion were not in conflict because they taught about the same things. Common people needed religion and faith to understand what the intellectual could understand through reason and logic. He felt proper understanding of the Koran required analytical thinking.

Unfortunately for him, his rationalist views often got him into trouble when they came up against Islamic theology (which he had studied extensively). He was, in fact, banished by a caliph to whom he had been the personal physician, because some side remarks in Averroes' writing (such as "that Venus is one of the gods") struck the caliph as blasphemous. Fortunately, Averroes was allowed to return home prior to his death.

We've looked at a few different philosophers. Next I want to talk about a particular medieval school of philosophy: scholasticism.

Thomas Aquinas

I suppose if we wanted to find a Christian parallel to Maimonides, Thomas Aquinas would be an obvious choice. Born into the aristocracy, noted for his learning and devoutness, his writing blending previous scholarship and building on it with impressive arguments backed up by Scripture and reason, his writings becoming foundational for what came after—no wonder he was nicknamed Doctor Angelicus ("The Angelic Doctor").

He was born in 1225 in the town of Aquino. His father was Count Landulph of Aquino, his mother Countess Theodora of Teano; he was related to the kings of Aragon, Castile, and France, as well as to Emperors Henry VI and Frederick II. A biography written a generation after he died claims that a holy hermit predicted to a pregnant Theodora that her child would become unequalled in learning and sanctity.

His education began at the typical age of five, with the Benedictines of Monte Cassino (his father's brother Sinibald was the abbot there from 1227-1236). Some time between 1236 and 1239 he was sent to a university at Naples where he would have first learned about Aristotle, Averroes, and Maimonides. Here he also came into contact with a Dominican preacher. The Dominicans had been founded 30 years earlier and were actively recruiting.

When he was 19 years old, Thomas announced that he wished to join the Dominicans, which displeased his "Benedictine-oriented" family. It displeased them so much that, while Thomas was traveling to Rome on his way to Paris to get away from the family's influence, his brothers (at his mother's request) kidnapped him. He was forced to stay in his parents' castle for almost a year, spending the time tutoring his sisters.

Attempts to dissuade him from the Dominicans became more desperate. His brothers sent a prostitute to seduce him. He fought her off with a burning log, then fell into a mystical trance and had a vision of two angels granting him perfect chastity. (They also gave him a "girdle of chastity" that now resides in Turin.) His mother, seeing that he would not change his mind, and not wanting to endure the embarrassment of allowing her son to join the Dominicans, she arranged for him to escape his home in 1244. He went to the University of Paris where he probably studied under Albertus Magnus. Because Thomas was quiet, his fellow students ridiculed him, but Albertus is supposed to have told them "You call him the dumb ox, but in his teaching he will one day produce such a bellowing that it will be heard throughout the world."

In 1256 he was appointed regent master in theology at Paris and began writing the first of his many theological works, Contra impugnantes Dei cultum et religionem ("Against Those Who Assail the Worship of God and Religion"), defending the mendicant orders.

His reputation as a theologian and teacher/preacher grew so much that he was granted the Archbishopric of Naples in 1265 by Pope Clement IV, but he turned it down. In the yard that followed he would have the time to write one of his greatest works, the Summa Theologica.

And this is where we come back to the comparison with Maimonides: despite the groundbreaking nature of his writing, which became foundational for much of what followed, he was not without his detractors. Some of his conclusions clashed with accepted thought from previous religious writers. To be able to discuss that, we should look at two other philosophers: Aristotle and Averroes. Stay tuned.

The Abbasid Caliphate

The Abbasid Caliphate has only been mentioned so far as a target of the Assassins, but deserves more attention. Descended from Muhammad's uncle Abbas, the caliphate took power from the Umayyad caliphate and ruled from 750 until its conquest by Mongols in 1258.

That means that the Abbasid Caliphate was "in charge" during many of the Islamic interaction with Europe mentioned in this blog:

• Abu Ma'shar, the Father of Arab Astrology, who brought commentaries on Aristotle to Western Europeans
• The astronomer Abd al-Rahman al-Sufi, who reconciled Greek and Arab star charts
• Averroes the Commentator
• Avicenna the surgeon
• ...and, of course, it was during this time that Algebra came to be

Besides math and philosophy, the Abbasid Caliphate was at the forefront of technology, adopting the use of Chinese paper-making techniques and gunpowder. Arabs developed the sextant, windmills for industrial use, and kerosene from petroleum.

The Abbasid's first capital was Kufa, on the banks of the Euphrates, but they shortly chose a different city, whose only shortcoming was that it did not exist.

On 30 July, 762, that would change; but that's a story for tomorrow.

One Soul To Guide Them All

Averroes (1126-1198) undertook to explain and comment on the works of Aristotle, in an attempt to clarify the Greek philosopher's concepts. One of those concepts was the idea of man's intellect, the debate over which was both stimulating and shocking for the medieval world.

Averroes (in turban); detail, "School of Athens" (Raphael)

Aristotle distinguished between a passive intellect, which is man's predisposition to accept and hold ideas, and an active intellect, which was the agent of analysis and creativity.* The active intellect was an outside force, and the blending or convergence of the external active intellect with the internal passive intellect differed in individuals, which is why we could strive to learn and think and better ourselves intellectually, but we were still different from each other. The connection between active and passive was not the same in each person. This accounted for different and individual personalities.

This was an obvious parallel to Aristotle's Realism: the idea that there exist "universal" abstract concepts—such as "dog"—outside of our direct experience, that allow us to directly experience multiple different dogs with different characteristics (which he called "particulars") and yet understand that they were all dogs.

Averroes explained this further, and created a religious controversy.

If the active intellect was external (and from a divine source) but the less-powerful passive intellect resided in man, and it was the blending of the two that created personality and human intelligence, then what happens at death when the external active intellect is removed? As a divine and lasting and (presumably) unchanging force, it stays as it is, unaffected by its temporary connection to an individual. The human-centered passive intellect dies with the human, the active intellect withdraws, and therefore there is no individual personality that exists anymore.

For Averroes, understanding Aristotle meant that there was no survival after death of a personality. Your personality—what makes you "you"—is gone when you die, and there is no room here for a soul with your personality to exist in an afterlife.

Orthodox Mohammedan theology did not agree with this, nor did Christian theologians such as St. Bonaventure and St. Thomas Aquinas.

Averroes defense against the charge of heresy? That reason forced him to express these thoughts, but that of course he adhered to the truth as explained by his faith.

*Aristotle used the term "intelligences" to refer to the non-physical (divine, or spiritual) forces that moved the celestial spheres. Christian thinkers would later call these "angels."

Nominalism vs Realism

Realism [link]

At the foundation of philosophy is a question: what defines reality? There are several questions that are connected to this. Let us start with: when we say that a lot of different animals are all dogs, to what quality are we referring that makes the Dachsund and the Great Dane both dogs? Is there an essential quality of "dog-ness"? Some universal concept that is inclusive of all dogs, despite the particular differences between breeds?

There it is: universals and particulars.

Realism says that both universals and particulars exist. That is, we recognize that different dogs/houses/trees are those things because, although they have different particulars, there is a universal essence of dogs/houses/trees that exists. Plato and Aristotle were Realists.

Nominalism says that the world is made only of particulars. Things we see are put into categories by our thought processes and our language, not by the existence of some abstract universal. William of Ockham and Jean Buridan were Nominalists.

In the two diagrams shown, we see that in Realism, although John and David have different Particulars, they are defined by their Universal quality as human beings. Nominalism, however, shows John and David only defined by their Particulars. The category of Humanity is created by us. There is no abstract "Humanity" essence that exists independent of John and David.

Nominalism [link]

Getting at the truth produced some fascinating thought experiments. One—The Puzzle of Theseus' Ship—was posed by Plutarch (46-120 CE). The ship of Theseus was preserved in Athens for several generations. As pieces of it decayed, they were replaced with new wood, so that the ship would stay intact. If a thing is based on its particulars, then with the particulars of this ship having changed over the years, is it still Theseus' ship? If there is some universal of Theseus' ship (as Realism says) then it is still his ship. If there are only particulars (as Nominalism says) then it isn't.

British philosopher Thomas Hobbes (1588-1679) took this a step further: if all the removed pieces were assembled into a complete ship, then which is Theseus' ship? Are they both Theseus' ship? He concludes that this would be absurd.

Even the early scholars understood that there were problems with these concepts, and struggled to reconcile the issues. Still, they did their best to understand how reality worked, and how that would help them to understand everything else.

...such as whether we have individual souls. That discussion will take us back to Averroes tomorrow.

The Commentator

Statue commemorating Averroes in Córdoba

Averroes (1126-1198) was born in Córdoba into a family of distinguished jurists and scholars at a time when Islamic culture was flourishing in Spain. He probably would have spent his life as a judge if not for his mentor and friend, the physician Abu Bakr ibn Tufayl, who told him that he should write commentaries on the works of Aristotle. The problem seen by ibn Tufayl was that Aristotle was too obscure either because of the ambiguity of his own writing or the shortcomings of his translators.

Averroes, whose real name was ʾAbū al-Walīd Muḥammad bin ʾAḥmad bin Rušd, embraced the task so thoroughly that, to the West, he became known as "The Commentator." His scholarship was embraced across cultures: Jacob Anatoli translated Averroes' Commentaries into Hebrew. Anatoli's colleague and friend Michael Scot translated some directly into Latin.

He analyzed and promoted most of Aristotle (and Plato's Republic) to the known world, as well as writing dozens of books of his own. So far as we know, he did not have access to original texts—there is no evidence that he knew Greek—and so his commentaries are based on Arabic translations of Aristotle.

He was, in fact, banished by a caliph to whom he had been the personal physician, because some side remarks in Averroes' writing (such as "that Venus is one of the gods") struck the caliph as blasphemous. Fortunately, Averroes was allowed to return home prior to his death.

One of his most radical ideas, based on Aristotle, was that there were multiple intellects, but only one shared soul for all of mankind. To explain that raises more questions, however, unless first we look at a debate I have been putting off for months. Tomorrow, therefore, we will (finally) discuss Nominalism vs. Realism.

Jacob Anatoli

Daily Medieval has frequently mentioned the importance of Arabic texts in the transmission of knowledge to Western Europe. Arabic, however, was not a commonly known language, and Arabs did not have a strong presence in Western Europe. Arabic culture often brushed up against Latin culture in the southern Mediterranean, as mentioned Salerno, or when a scholar such as Michael Scot made it a point to learn Arabic. Scot probably had help in the form of Jacob Anatoli.

Jacob ben Abba Mari ben Simson Anatoli (c.1194-1256) grew up in southern France, and gained such a reputation for scholarship that he was invited to Naples by Frederick II, who gathered several other academics to his court, such as Scot and Fibonacci. Anatoli became known for his translations of Arabic texts into Hebrew, and he very likely aided Michael Scot in his Arabic translations. Roger Bacon explains that Scot was aided by a Jew named Andreas, and some scholars believe "Andreas" to be a misunderstanding of "Anatoli."

Of his non-translations, the greatest work is the Malmad ha-Talmidim (the title is a pun, being interpreted either "Teacher of the Students" or "Goad to the Students"). The Malmad shows a wide range of knowledge, incorporating the Old Testament and Jewish commentators, but also the New Testament, Aristotle, Plato, and Averroes. His egalitarian approach to Christian and Muslim matters was refreshing, but Judaism still had special status; he wrote "the Greeks had chosen wisdom as their pursuit; the Romans, power; and the Jews, religiousness." He tells us that a non-Jew who seeks religious Truth should be respected by Judaism and not mocked.

Anatoli extended this intellectual courtesy to Frederick II, incorporating remarks by the emperor in his works. He also mentions a Christian whom Anatoli considers a second master (after Anatoli's own mentor, Samuel ibn Tibbon); this "master" has been equated to Michael Scot.

As for his Arabic translations, Anatoli's crucial contribution was exposing the West to the work of Averroes, one of two Arab scholars (the other was the medical expert Avicenna) whose work is considered fundamental to the Middle Ages.We'll look at Averroes tomorrow.
