Averroes

Template:Infobox Philosopher Ibn-Rushd (Arabic: ابن رشد), known as Averroes (1126 – December 10, 1198), was an Andalusian-Arab philosopher, physician, and polymath: a master of philosophy, Islamic law, astronomy, geography, mathematics, medicine, physics, and science. He was born in Cordoba, Spain, and died in Marrakech, Morocco. His school of philosophy is known as Averroism. He has been described as the founding father of secular thought in Western Europe.

His name is also seen as Averroès, Averroës or Averrhoës, indicating that the o and the e form separate syllables. In Arabic (the language in which he wrote), his name is Abu al-Walid Muhammad Ibn Ahmad Ibn Rushd أبو الوليد محمد بن احمد بن رشد or just Ibn Rushd. In modern Tamazight (the language of the Almohad Khalifs) it would be Muḥemmed mmis n Ḥmed mmis n Muḥemmed mmis n Ḥmed mmis n Rucd.

Biography

Ibn Rushd came from a family of Maliki legal scholars; his grandfather Abu Al-Walid Muhammad (d. 1126) was chief judge of Cordoba under the Almoravids. His father, Abu Al-Qasim Ahmad, held the same position until the coming of the Almohad dynasty in 1146. It was Ibn Tufail ("Abubacer" to the West), the philosophic vizier of Almohad Caliph Abu Yaqub Yusuf, who introduced Averroes to the court and to Avenzoar (Ibn Zuhr), the great Muslim physician; both men became friends. In 1160 Ibn Rushd (Averroes) was made Qadi of Seville and he served in many court appointments in Seville and Cordoba, and in Morocco during his career. At the end of the 12th century, following the Almohads conquest of Al-Andalus, his political career was ended. Averroes' strictly rationalist views which collided with those of Islamic orthodoxy had caused Abu Yusuf Ya'qub al-Mansur to banish him though he had previously appointed him his personal physician. Averroes was not rehabilitated until shortly before his death. He devoted the rest of his life to his philosophical writings.

Works

He wrote commentaries on most of the surviving works of Aristotle. These were not based on primary sources (it is not known whether he knew Greek), but rather on Arabic translations. On each work, he wrote the Jami, the Talkhis and the Tafsir which are, respectively, a simplified overview, an intermediate commentary with more critical material, and an advanced study of Aristotelian thought in a Muslim context. The terms are taken from the names of different types of commentary on the Qur'an. He did not have access to any text of Aristotle's Politics. As a substitute for this, he commented on Plato's Republic, arguing that the state there described was the same as the original constitution of the Arabs.

His most important original philosophical work was The Incoherence of the Incoherence (Tahafut al-tahafut), in which he defended Aristotelian philosophy against al-Ghazali's claims in The Incoherence of the Philosophers (Tahafut al-falasifa). Al-Ghazali argued that Aristotelianism, especially as presented in the writings of Avicenna, was self-contradictory and an affront to the teachings of Islam. Averroes' rebuttal was two-pronged: he contended both that al-Ghazali's arguments were mistaken and that, in any case, the system of Avicenna was a distortion of genuine Aristotelianism so that al-Ghazali was aiming at the wrong target. Other works were the Fasl al-Maqal, which argued for the legality of philosophical investigation under Islamic law, and the Kitab al-Kashf.

Averroes is also a highly-regarded legal scholar of the Maliki school. Perhaps his best-known work in this field is Bidāyat al-Mujtahid wa Nihāyat al-Muqtaṣid ( بدايات المجتهد و نهايات المقتصد), a textbook of Maliki doctrine in a comparative framework. He is also the author of al-Bayān wa’l-Taḥṣīl, wa’l-Sharḥ wa’l-Tawjīh wa’l-Ta`līl fi Masā’il al-Mustakhraja, a long and detailed commentary based on the Mustakhraja of Muḥammad al-`Utbī al-Qurtubī.

In medicine, Averroes wrote a medical encyclopedia called Kulliyat ("Generalities", i.e. general medicine), known in its Latin translation as Colliget. He also made a compilation of the works of Galen (129-200) and wrote a commentary on The Canon of Medicine (Qanun fi 't-tibb) of Avicenna (Ibn Sina) (980-1037).

Jacob Anatoli translated several of the works of Averroes from Arabic into Hebrew in the 1200s. Many of them were later translated from Hebrew into Latin by Jacob Mantino and Abraham de Balmes. Other works were translated directly from Arabic into Latin by Michael Scot. Many of his works in logic and metaphysics have been permanently lost, while others, including some of the longer Aristotelian commentaries, have only survived in Latin or Hebrew translation, not in the original Arabic. The fullest version of his works is in Latin, and forms part of the multi-volume Juntine edition of Aristotle published in Venice 1562-1574.

Contributions

Philosophy

According to him, there is no conflict between religion and philosophy, rather that they are different ways of reaching the same truth. He believed in the eternity of the universe. He also held that the soul is divided into two parts, one individual and one divine; while the individual soul is not eternal, all humans at the basic level share one and the same divine soul. Averroes has two kinds of Knowledge of Truth. The first being his knowledge of truth of religion being based in faith and thus could not be tested, nor did it require training to understand. The second knowledge of truth is philosophy, which was reserved for an elite few who had the intellectual capacity to undertake its study.

Psychology

H. Chad Hillier writes the following on Averroes' contributions to psychology:

"There is evidence of some evolution in Ibn Rushd's thought on the intellect, notably in his Middle Commentary on De Anima where he combines the positions of Alexander and Themistius for his doctrine on the material intellect and in his Long Commentary and the Tahafut where Ibn Rushd rejected Alexander and endorsed Themistius’ position that "material intellect is a single incorporeal eternal substance that becomes attached to the imaginative faculties of individual humans." Thus, the human soul is a separate substance ontologically identical with the active intellect; and when this active intellect is embodied in an individual human it is the material intellect. The material intellect is analogous to prime matter, in that it is pure potentiality able to receive universal forms. As such, the human mind is a composite of the material intellect and the passive intellect, which is the third element of the intellect. The passive intellect is identified with the imagination, which, as noted above, is the sense-connected finite and passive faculty that receives particular sensual forms. When the material intellect is actualized by information received, it is described as the speculative (habitual) intellect. As the speculative intellect moves towards perfection, having the active intellect as an object of thought, it becomes the acquired intellect. In that, it is aided by the active intellect, perceived in the way Aristotle had taught, to acquire intelligible thoughts. The idea of the soul's perfection occurring through having the active intellect as a greater object of thought is introduced elsewhere, and its application to religious doctrine is seen. In the Tahafut, Ibn Rushd speaks of the soul as a faculty that comes to resemble the focus of its intention, and when its attention focuses more upon eternal and universal knowledge, it become more like the eternal and universal. As such, when the soul perfects itself, it becomes like our intellect."

"Ibn Rushd succeeded in providing an explanation of the human soul and intellect that did not involve an immediate transcendent agent. This opposed the explanations found among the Neoplatonists, allowing a further argument for rejecting of Neoplatonic emanation theories. Even so, notes Davidson, Ibn Rushd’s theory of the material intellect was something foreign to Aristotle."

Astronomy

In astronomy, Averroes rejected the eccentric deferents introduced by Ptolemy. He rejected the Ptolemaic model and instead argued for a strictly concentric model of the universe. He wrote the following criticism on the Ptolemaic model of planetary motion:

"To assert the existence of an eccentric sphere or an epicyclic sphere is contrary to nature. [...] The astronomy of our time offers no truth, but only agrees with the calculations and not with what exists."

Averroes also argued that the Moon is opaque and obscure, and has some parts which are thicker than others, with the thicker parts receiving more light from the Sun than the thinner parts of the Moon. He also gave one of the first descriptions on sunspots.

Logic

Averroes was the last major Muslim logician from al-Andalus. He is known for writing the most elaborate commentaries on Aristotelian logic.

Physics

In Averroes' commentary on Aristotle's Physics, he commented on the theory of motion proposed by Ibn Bajjah (Avempace) in Text 71, and also made his own contributions to physics and mechanics.

Averroes was the first to define and measure force as "the rate at which work is done in changing the kinetic condition of a material body" and the first to correctly argue "that the effect and measure of force is change in the kinetic condition of a materially resistant mass."

Significance

Averroes is most famous for his translations and commentaries of Aristotle's works, which had been mostly forgotten in the West, and for his early secular thought. Before 1150, only a few translated works of Aristotle existed in Latin Europe, and they were not studied much or given much credence by monastic scholars. It was through the Latin translations of Averroes's work beginning in the 12th century that the legacy of Aristotle became more widely known in the medieval West.

Averroes' separation of reason and religion in The Decisive Treatise provided a justification for the doctrine of separation of religion and state, thus Averroism is considered by some writers as a precursor to modern secularism, and the founding father of secular thought in Western Europe. George Sarton, the father of the history of science, writes:

"Averroes was great because of the tremendous stir he made in the minds of men for centuries. A history of Averroism would include up to the end of the sixteenth-century, a period of four centuries which would perhaps deserve as much as any other to be called the Middle Ages, for it was the real transition between ancient and modern methods."

Averroes's work on Aristotle spans almost three decades, and he wrote commentaries on almost all of Aristotle's work except for Aristotle's Politics, to which he did not have access. Hebrew translations of his work also had a lasting impact on Jewish philosophy. His ideas were assimilated by Siger of Brabant and Thomas Aquinas and others (especially in the University of Paris) within the Christian scholastic tradition which valued Aristotelian logic. Famous scholastics such as Aquinas believed him to be so important they did not refer to him by name, simply calling him "The Commentator" and calling Aristotle "The Philosopher." Averroes also greatly influenced philosophy in the Islamic world. His death coincides with a change in the culture of Al-Andalus. In his work Fasl al-Maqāl (translated a. o. as The Decisive Treatise), he stresses the importance of analytical thinking as a prerequisite to interpret the Qur'an; this is in contrast to orthodox Muslim theology, where the emphasis is less on analytical thinking but on extensive knowledge of sources other than the Qur'an, i.e. the hadith.

Averroes's treatise on Plato's Republic has played a major role in both the transmission and the adaptation of the Platonic tradition in the West. It has been a primary source in medieval political philosophy.

Reflecting the respect which medieval European scholars paid to him, Averroes is named by Dante in The Divine Comedy with the great pagan philosophers whose spirits dwell in "the place that favor owes to fame" in Limbo.

Averroes appears in a short story by Jorge Luis Borges, entitled "Averroes's Search", in which he is portrayed trying to find the meanings of the words tragedy and comedy. He is briefly mentioned in the novel Ulysses by James Joyce alongside Maimonides. He appears to be waiting outside the walls of the ancient city of Cordoba in Alamgir Hashmi's poem In Cordoba. He is also the main character in Destiny, a Youssef Chahine film. The asteroid 8318 Averroes was named in his honor.
