Ibn Rushd (Averroes) 1126-1198 (Medicine, Philosophy)

Ibn Rushd was the major philosopher of the 12th century who lived in Cordoba from 1126 to 1198 and was a contemporary of the great Jewish Rabbi and philosopher Maimonides.  Toward the end of Ibn Rushd’s life he encountered severe censorship, after the Almohad invasions of Andalusia that enforced strict censorship and the banning and burning of his books and forced him to exile and to seek refuge in the  predominantly Jewish village of Lucena outside of Cordoba (Hillier 2016).  Ibn Rushd is best known for his commentaries on Aristotle and for his attack on Al-Ghazali (d. 1111) in a who upheld an Ash’arite theology, also known as the Mutakallimun.  Al-Ghazali had written a long work that attacked the philosophy of Ibn Sina and that attacked philosophy in general.  Ibn Rushd wrote a long work that took apart Al-Ghazali’s argument and that instead defended philosophy as a subject that could exist with or independently from faith.  Ibn Rushd’s commentaries on Aristotle were also of vital importance in the history of philosophy, for these texts were translated into Latin and held great influence at the University of Paris in the mid 1200s where figures like Albert Magnus, Thomas Aquinas and Roger Bacon debated its merits.  For Aquinas Averroes and the school of philosophy known as Averroism was dangerous and so he sought to defend the inseparability of faith and reason in his Summa Theologiae. Those who followed Averroes’ teachings were accused of denying the infinity of the soul.  Interestingly a group of Jewish philosophers from Cordoba, including Maimonides would absorb and modify a number of his key ideas.

Despite the advances in Ibn Rushd’s philosophical defense of rationalism, as with Ibn Sina, there are a number of weaknesses that show the limits of physical knowledge.  Like Ibn Sina, Ibn Rushd believed in spontaneous generation and also dismissed Al-Ghazali’s interesting mention of the calculable differences of planetary orbits.  He also upholds a cosmology in which the Earth is the center around which all objects rotate.  This mirrors his implied view of a political order in which the monarch or ruler is at the center all other subordinates are moved and kept in order by rank (Hillier 2016).
