Avicenna
Avicenna, also known as Ibn Sina, was a prominent Persian polymath born in the late 10th century in present-day Afghanistan. He is best known for his contributions to philosophy, medicine, and the natural sciences, which laid foundational concepts that influenced both Islamic and Western thought. Avicenna exhibited an exceptional intellect from a young age, mastering complex subjects such as Aristotelian philosophy and medicine by his teenage years. His most significant work, the "Canon of Medicine," became a vital text in medical education for centuries, illustrating his advanced understanding of health, disease, and treatment methods.
Beyond medicine, Avicenna's philosophical writings and theories, particularly regarding essence and existence, had a profound impact on later thinkers, including Thomas Aquinas and Averroës. He is credited with fostering an intellectual renaissance in the Islamic world that extended into Europe, impacting various fields including astronomy and ethics. His invention of literary forms, such as the Rubaiyat, also showcases his versatility as a writer. Avicenna's legacy endures through the centuries, as his insights into observation and experimentation echo in the foundations of modern scientific thought. He passed away in 1037, leaving behind a vast body of work that continues to inform various disciplines today.

Avicenna was the first Islamic thinker to synthesize the philosophy of Aristotle and Plato with Islamic traditions. His writings on medicine were studied in Europe as late as the seventeenth century.
Early Life
Avicenna (av-a-SEHN-a) was born to ՙAbd-Allāh of Balkh (now in Afghanistan), the well-to-do governor of an outlying province under Sāmānid ruler Nūh II ibn Manṣūr. Avicenna may have descended from a Turkish family on his father's side, but his mother, Sitara, was clearly Iranian.

After his brother, Maḥmūd, was born five years later, the family moved to Bukhara, one of the principal cities of Transoxiana and capital of the Sāmānid emirs from 819 to 1005. Exhibiting an early interest in learning, young Avicenna had read the entire Qur՚ān by age ten. His father was attracted to Ismālī Shīՙite doctrines, preached locally by Egyptian missionaries, but Avicenna resisted his father's influence. There was much discussion in his home regarding geometry, philosophy, theology, and even accounting methods. Avicenna was sent to study with an Indian vegetable seller who was also a surveyor. It was from him that Avicenna became acquainted with the Indian system of calculation, making use of the zero in computations.
A well-known philosopher came to live with the family for a few years and had an extraordinary influence on the young scholar. Abū ՙAbd Allāh al-Natili stimulated Avicenna's love of theoretical disputation, and the youth's earlier readings in jurisprudence enabled him to tax al-Natili's powers of logic daily. The tutor convinced ՙAbd-Allāh that Avicenna's career should be only in learning. Avicenna was studying Aristotelian logic and Euclidean geometry when the teacher decided to move to a different home. Soon Avicenna had mastered texts in natural sciences and metaphysics, then medicine, which he did not consider very difficult. He taught physicians, even practicing medicine for a short time. At the age of sixteen, he was also engaging in disputations on Muslim law.
For the next year and a half, Avicenna returned to the study of logic and all aspects of philosophy, keeping files of syllogisms and praying daily at the mosque for guidance in his work. So obsessed did he become with philosophical problems and so anxious to know all that he hardly took time for sleep. Aristotle's Metaphysica (Metaphysics) became an intellectual stumbling block until his reading of a work by al-Fārābi clarified many ideas for him. Soon all of Aristotle became understandable, and Avicenna gave alms to the poor in gratitude.
When Sultan Nūh ibn Manṣūr of Bukhara became ill, he sent for Avicenna, on the advice of his team of physicians. Because of his help in curing the ruler, Avicenna gained access to the palace library, thus acquainting himself with many new books. When not studying, Avicenna was given to drinking wine and satisfying a large sexual appetite that he retained to the end of his life. Avicenna claimed that after the age of eighteen he learned nothing new, only gained greater wisdom. When the palace library was destroyed in a fire, critics blamed Avicenna, who, they said, wished to remove the sources of his ideas. There is no proof of that charge.
Life's Work
Avicenna's writing career began in earnest at the age of twenty-one with al-Majmu (1001; compilation), a comprehensive book on learning for Abū al-Ḥasan, a prosodist. Then he wrote al-Hasil wa al-mahsul (c. 1002; the sun and substance), a twenty-volume commentary on jurisprudence, the Qur՚ān, and asceticism. There soon followed a work on ethics called al-Birr wa al-ithm (c. 1002; good works and evil). The sponsors made no copies of them, a matter of some concern to the author.
His father died in 1002, and Avicenna was forced to take government service. He reluctantly left Bukhara for Gurganj, the capital of Khwārezm, where he met Emir ՙAlī ibn Ma՚mūn. From Gurganj, he moved to Fasa, Baward, Ṭūs, Samanqan, and then to Jajarm on the extreme end of Khorāsān. Avicenna served Emir Qābūs ibn Wushmagir until a military coup forced him to leave for Dihistan, where he became ill. After recovering, he moved to Jurjan.
In Jurjan, Avicenna met his pupil and biographer, Abū ՙUbayd al-Juzjani , who stayed with him throughout much of the remainder of his life. Al-Juzjani thought him exceptionally handsome and wrote that when Avicenna went to the mosque on Friday to pray, people would gather to observe firsthand “his perfection and beauty.” While in Jurjan, Avicenna wrote al-Mukhtasar al-awsat (the middle summary on logic), al-Mabdaՙ wa al-maՙād (the origin and the return), and al-Arsad al-kulliya (comprehensive observations). There also Avicenna wrote the first part of al-Qanun fi al-tibb (1010-1015; Canon of Medicine , 1930), Mukhtasar al-Majisti (summary of the Almagest), and yet other treatises. One modern scholar lists one hundred books attributed to him. Another says that the list of Avicenna's works includes several hundred in Arabic and twenty-three in Persian.
From Jurjan, Avicenna next moved to al-Rayy, joining the service of al-Saiyyida and her son, Majd al-Dawlah. Civil strife forced him to flee to Qazwin; from there he moved to Hamadhan. He was called to the court of Emir Shams al-Dawlah to treat the ruler for colic, after which Avicenna was made the vizier of his emirate. Because of a mutiny in the army, however, the emir was forced to discharge him. After matters calmed down, Avicenna was called back and reinstated as vizier. During this period, public affairs occupied his daytime hours, and he spent evenings teaching and writing. When the emir died, Avicenna went into hiding, finishing work on his Kitāb al-shifa (book of healing; partially translated, 1927). He was arrested for corresponding with a rival ruler, but when Emir Alā al-Dawlah attacked Hamadhan four months later, Avicenna was set free.
Avicenna left Hamadhan for Isfahan with his brother, two slaves, and al-Juzjani to serve Emir ՙAla al-Dawlah. The emir designated every Friday evening for learned discussions with many other masters. Not present was a famous scholar and rival of Avicenna, al-Bīrūnī, with whom he carried on a rather bitter correspondence. They had been clients at many of the same courts, but never at the same time. At Isfahan, Avicenna completed many of his writings on arithmetic and music. He was made an official member of the court and accompanied the emir on a military expedition to Hamadhan.
When he was rebuked by the emir's cousin, Abū Manṣūr, for feigning expertise in philology, Avicenna was so stung by the criticism that he studied this subject frantically, compiling his discoveries in a book entitled Lisan al-ՙArab (the Arabic language). During these years, he also continued other experiments in medicine and astronomy . He introduced the use of medicinal herbs and devised an instrument to repair injured vertebrae. He understood that some illnesses arose from psychosomatic causes, and he wrote extensively on the pulse, preventive medicine, and the effects of climate on health. On May 24, 1032, he observed the rare phenomenon of Venus passing through the solar disk.
When he became ill in Isfahan, one of his slaves filled his meal with opium, hoping for his death and an opportunity to steal his money. Yet Avicenna managed to recover under self-treatment. Soon, however, he had a relapse; he died in 1037. Most authorities say that he died and was buried in Hamadhan.
Significance
The Canon of Medicine remained a principal source for medical research for six centuries, perhaps second only to the Christian Bible in the number of copies produced. Between 1470 and 1500, it went through thirty editions in Latin and one in Hebrew; a celebrated edition was published on a Gutenberg press in Rome in 1593. Avicenna's principal literary contribution was the invention of the Rubaiyat form, quatrains in iambic pentameter, later made famous by Omar Khayyám. Most important of all, Avicenna's philosophical system helped to stimulate a genuine intellectual renaissance in Islam that had enormous influence not only in his own culture but in Western Europe as well. Thomas Aquinas, Averroës, John Duns Scotus, Albertus Magnus, and Roger Bacon learned much from Avicenna, even though they disagreed on some particulars.
Most intriguing to the medieval Scholastics were Avicenna's insistence on essences in everything, the distinction between essence and existence (a notion derived from al-Fārābi), the absence of essence in God (whose existence is unique), and the immortality of the soul (which animates the body but is independent of it).
According to some scholars, Avicenna's insistence on observation and experimentation helped to turn Western thought in the direction of the modern scientific revolution. His theories on the sources of infectious diseases, his explanation of sight, his invention of longitude, and his other scientific conclusions have a truly remarkable congruence with modern explanations. The application of geometrical forms in Islamic art, his use of the astrolabe in astronomical experiments, and his disputations on the immortality of the soul demonstrate Avicenna's universal genius.
