Avicenna (Persian: پور سینا‎) (c. 980 – June 1037), is the Latinate form of Ibn-Sīnā (Arabic: ابن سینا‎), full name Abū ʿAlī al-Ḥusayn ibn ʿAbd Allāh ibn Al-Hasan ibn Ali ibn Sīnā (أبو علي الحسين ابن عبد الله ابن سينا). He was a Persian polymath regarded both in Europe and the Middle East as one of the most significant thinkers and writers of the Islamic Golden Age. He is known to have written around 450 works across a wide range of subjects, of which around 240 have survived, including 150 on philosophy and 40 on medicine. His most famous works are The Book of Healing – a vast philosophical and scientific encyclopedia – and The Canon of Medicine, an overview of all aspects of medicine that became a standard medical text at many medieval universities and remained in use as late as 1650. As well as philosophy and medicine, Avicenna's corpus also includes writings on astronomy, alchemy, geography and geology, psychology, Islamic theology, logic, mathematics, physics and poetry. Avicenna created an extensive corpus of works during what is commonly known as the Islamic Golden Age, in which the translations of Greco-Roman, Persian, and Indian texts were studied extensively. Greco-Roman (Mid- and Neo-Platonic, and Aristotelian) texts by the Kindi school were commented, redacted and developed substantially by Islamic intellectuals, who also built upon Persian and Indian mathematical systems, astronomy, algebra, trigonometry and medicine. The Samanid dynasty in the eastern part of Persia, Greater Khorasan and Central Asia as well as the Buyid dynasty in the western part of Persia and Iraq provided a thriving atmosphere for scholarly and cultural development. Under the Samanids, Bukhara rivaled Baghdad as a cultural capital of the Islamic world. The study of the Quran and the Hadith thrived in such a scholarly atmosphere. Philosophy, Fiqh and theology (kalaam) were further developed, most noticeably by Avicenna and his opponents. Al-Razi and Al-Farabi had provided methodology and knowledge in medicine and philosophy. Avicenna had access to the great libraries of Balkh, Khwarezm, Gorgan, Rey, Isfahan and Hamadan. Various texts (such as the 'Ahd with Bahmanyar) show that he debated philosophical points with the greatest scholars of the time. Aruzi Samarqandi describes how before Avicenna left Khwarezm he had met Rayhan Biruni (a famous scientist and astronomer), Abu Nasr Iraqi (a renowned mathematician), Abu Sahl Masihi (a respected philosopher) and Abu al-Khayr Khammar (a great physician). Biography Early life The only source of information for the first part of Avicenna's life is his autobiography, as written down by his student Jūzjānī. In the absence of any other sources it is impossible to be certain how much of the autobiography is accurate. It has been noted that he uses his autobiography to advance his theory of knowledge (that it was possible for an individual to acquire knowledge and understand the Aristotelian philosophical sciences without a teacher), and it has been questioned whether the order of events described was adjusted to fit more closely with the Aristotelian model; in other words, whether Avicenna described himself as studying things in the 'correct' order. However given the absence of any other evidence, Avicenna's account essentially has to be taken at face value. Avicenna was born c. 980 in Afšana, a village near Bukhara (in present-day Uzbekistan), the capital of the Samanids, a Persian dynasty in Central Asia and Greater Khorasan. His mother, named Setareh, was from Bukhara; his father, Abdullah, was a respected Ismaili scholar from Balkh, an important town of the Samanid Empire, in what is today Balkh Province, Afghanistan. His father was at the time of his son's birth the governor in one of the Samanid Nuh ibn Mansur's estates. He had his son very carefully educated at Bukhara. Ibn Sina's independent thought was served by an extraordinary intelligence and memory, which allowed him to overtake his teachers at the age of fourteen. As he said in his autobiography, there was nothing that he had not learned when he reached eighteen. A number of different theories have been proposed regarding Avicenna's madhab. Medieval historian Ẓahīr al-dīn al-Bayhaqī (d. 1169) considered Avicenna to be a follower of the Brethren of Purity. On the other hand, Dimitri Gutas along with Aisha Khan and Jules J. Janssens demonstrated that Avicenna was a Sunni Hanafi. However, Shia faqih Nurullah Shushtari and Seyyed Hossein Nasr, in addition to Henry Corbin, have maintained that he was most likely a Twelver Shia. Similar disagreements exist on the background of Avicenna's family, whereas some writers considered them Sunni, more recent writers thought they were Shia.
