Al-Andalus wisemen: Averroes

CONTEXT

Averroes was born when the Almoravids controlled Al-Andalus. They had crossed the Gibraltar Strait to help the Taifas kingdoms and they had defeated the Castilians. They extended their control over Al-Andalus until 1145, when protests against them increased and the Almohads crossed the Gibraltar Strait. This coincided with Averroes’ youth. The Almohads followed a rigid interpretation of Islam and claimed against the relaxation of customs under the Almoravid rule. They moved the capital city from Córdoba to Seville. The Almohad Empire was a period of cultural splendor and economic and scientific development (Islam didn’t forbid research). Al-Andalus was a centralized State. The caliph held political and spiritual power and he ruled with the help of the hayib (prime minister), appointed the governors of the provinces (walis) and the judges of the cities (qadis). Al-Andalus society was ethnically and religiously plural. The non-Muslims had to be respected and paid more taxes, but they could live in Al-Andalus without much problem, except in periods of religious intolerance, like the Almohad Empire. Al-Andalus finished with the ruralization and proto-feudalization processes and it recovered the splendor of the Roman Empire.


AVERROES

Abu I-Walid Muhammad ibn Rusd, known in the Latin world as Averroes, was born in Córdoba in 520/1126 during the Almoravid Andalusian time in a family of judges. His grandfather was qadi and imam of Córdoba’s mosque and the author of a famous legal treatise. His father, also qadi of Córdoba, taught him Muslim jurisprudence and introduced him to important thinkers from Córdoba, like Abu Ya’far Harun of Trujillo, from whom he got familiar with Aristotle, Galenus and Hipocrates. He also studied medicine with Avenzoar and he read Avempace’s books. Averroes was named qadi in Seville in 1169, after being introduced to the caliph Yusuf by the doctor of the court, Ibn Tufayl, who was another important Hispano-Arab philosopher. At first, Averroes hesitated about accepting, because he knew the risks of being a philosopher in an environment which usually identified them with heresy. However, when he saw that the caliph asked dangerous questions, he accepted.  The caliph rewarded him with a horse, a fur jacket and a good sum of money. He came back years later to Córdoba because he was appointed doctor of the caliph of Córdoba and later he was appointed Main Judge of Córdoba. He was the doctor of the Almohad caliph of Morocco and Al-Andalus. With the successor of Yusuf, Yaqub al-Mansur (1184-1199), honors continued. Nevertheless, in 1195, the caliph gave in to the desire of the theologians and issued a decree against profane sciences like philosophy. So, the caliph ordered the confinement of Averroes and Avenzoar in Lucena, the old Jewish city of Al-Andalus (it was a suburb), near the city of Córdoba. The citizens applauded that decision. His philosophy books were burnt because the edict denounced them as dangerous for Islam. Averroes thought that reason has priority over religion. He thought that religious conceptions are only an allegoric masking of the pure philosophic truth. This is called “theory of the two truths”. That’s why many of his works have been lost forever and we can only know them through translations into Hebrew and Latin. He died after the time the caliph let him come back from the exile in Marrakech in 595/1198. Averroes was always studying and thinking, to such an extent that one of his biographers says that he didn’t stop studying since he was of sound mind until his death, except the day of his wedding and the day of his father’s death.





He was interested in all the fields of knowledge such as philosophy, theology, mathematics, physics, astronomy, law, medicine, poetry, and he had a deep knowledge of the ancient Greek thought.

The most important part of his work are explanations, comments and critiques of interpretations of previous philosophers, applying the rules of the Middle East wisemen of the end of the 10th century and beginning of 11th century Ibn al-Haytam, who thought that it was necessary to analyze the texts from every point of view, and not to have previous ideas in favour or against the things we can read. However, Ibn Sab’in sustained that Averroes thought about the same things Aristotle had said.

Averroes wrote comments on the work of Aristotle. It deals with the harmony between religion and philosophy, trying to define the relationship between them clearly. Some of his most important works are Comments to Aristotle (Mayor Comment, Medium Comment and Small Comment). Averroes shared with Aristotle and Plato a similar idea about anthropology and knowledge. He thought that human knowledge is captured by senses and imagination and it isn’t objective (it corresponds to phenomenal reality), while divine knowledge doesn’t depend from things that are external to the mind (it corresponds to the reality of the universe. This knowledge is at the same time identical to God).

He wrote Solution to problem: creation or eternity of the world, where he defended that knowledge of God is the origin of the world, so world, as God, can’t have a start or end.
Averroes appears in The School of Athens. He is the man with a moustache who is located in the upper and left corner.

In his work Destructio destructionis he attacks al-Gazali, who thought that philosophy is in contradiction with religion and in this way philosophy is against the Muslim religion principles.

Averroes thought that the true religion was in the sacred Hebrew, Christian and Muslim books. But those books are directed to all the men and not all of them have the same ability to understand. The authentic truth can only be reached by philosophers, who base their knowledge in rigorous and absolutely logical demonstrations. The obligation of philosophers for Averroes is to discover the ideas hidden under images and symbols of the sacred books.

He believed in monopsyquism, that is, he defended the existence of a unique soul. He thought that individual souls are only different demonstrations of that unique soul. He defended this theory despite it was opposite to monotheistic religions. Averroes thought that no hope of eternity exists. The individual soul is destined to die with the body.

His ideas had big influence in the thought of Thomas Aquinas and his comments about Aristotle had big echo in the medieval Europe, being recognized like an authentic philosopher, although the French Ernest Renan, in the 19th century, rejected the originality of his thought.

In Law, he got fame of great lawyer and he wrote The Distinguished Jurist Primer, which is a textbook of Maliki doctrine in a comparative framework. Maliki doctrine is one of the four schools of law that exist in Sunni Islam. It represents the city of Medina’s tradition. Nowadays, it is predominant in Occidental Sahara, Mauritania, Morocco, Tunisia, Algeria, Libya, Kuwait, Bahrain and UAE. One important characteristic of Maliki doctrine is flexibility: rules adjust to the different situations of each country. This is why it applies successfully in so many countries.

Averroes was one of the biggest doctors of the period, although his medical work has been almost forgotten because of his fame as a philosopher. He studied with Avenzoar and he is the author of treatises that had a big diffusion until the Renaissance and of which different versions were made to the Hebrew and to the Latin. The medical texts of Averroes are of two types:

  • Medical works where he alludes to all the medical subjects treated by the most important Arab doctors and by some Greek philosophers. The most important texts in this group are:
1.    About the conservation of the health.
2.    Assertion about the different temperaments.
3.    Book of the Generalities in Medicine (written between 1162 and 1169): it consists of seven volumes, dedicated to anatomy, physiology, pathology, semeiotic, therapeutic, hygiene and medication. It was translated to Latin, as all of his works, and it was very used as text book in Christian universities: Paris, Oxford, Rome, Leuven and so on.
  • Texts made to comment Aristotle, Avicenna and Galenus: there are nine titles related to the Temperaments, Elements, Medicines, Fevers, Natural faculties and so on, by Galenus and a comment about the medicine of Avicenna.
In summary, his works are a compendium of the Arabic knowledge in physiology, pathology, diagnosis, medical matter and, even, anatomy, branch of the medicine that had lower impulse, since the Muslim religion did not allow the dissection of corpses. He was the first to explain the function of the retina and realize that an attack of smallpox causes immunity.

Averroes is also author of several small books about Ethics, Politics, Mathematics and Astronomy. He formulated the dogma, suggested already by Aristotle and reiterated later by Descartes in the 18th century, that any algebraic curve can be rectified in an exact way.

Averroes refused most of the Platonic ideas, and this implied the rejection of the ideas of the Arab philosophers of the Middle East, especially Avicenna.

In Astronomy he rectified very important Ptolemaic concepts (Ptolemy based his astronomical theories in a Platonic idea of the world) like the ones of the eccentric (Ptolemaic geocentric theory opposed Aristotelian physics. For example, orbits of his system are eccentric and the orbits of Plato and Aristotle are circular and perfect) and the epicycles (Ptolemy thought that the Earth doesn’t move and he tried to solve the problems about planetary movement with his model of the epicycle). This critique of Averroes to the Ptolemaic system had a very important influence in Copernicus, the one who, centuries afterwards, would cause a revolution in Astronomy.

His main detractors were Thomas Aquinas, Albertus Magnus and Parisian teachers of the 13th century. Aquinas and Magnus refused, for example, the theories that defend the eternity of the world, the movement and unity of the souls of all of men. Aquinas said that Averroes had twisted Aristotle’s teachings. Nevertheless, Averroes had a big influence in the Christian and Jewish scholastic and philosophy of the Middle Ages. In 1277, Archbishop Stefano Tempier condemned 219 theses sustained by philosophers who shared ideas with Averroes and Aristotle and he started a polemic which didn’t finish until Renaissance.

With respect to his followers, some teachers like Sigerius of Brabant and Boetius of Dacia taught theories of Averroes related with monopsyquism and defended a radical Aristotelianism which came from Averroes teachings. The teachers of Padua also taught his theories in the 15th century. Some experts have said that Averroes scholastic of Pietro Pomponazzi and Cesare Cremonini is the origin of the modern world. The orientation influenced by Averroes that raised Aristotle over the Bible was spread since the 13th century among teachers of secular formation who controlled universities of scientiae (Music, Geometry).

In the East, Averroes ideas were less known than in Europe.
