When did Avicenna live?

One of the greatest Persian medics was Avicenna, also known as Ibn Sina, who lived from 980AD to 1037AD. His works included a comprehensive collection and systematisation of the fragmentary and unorganised Greco-Roman medical literature that had been translated Arabic by that time, augmented by notes from his own experiences. One of his books, "Al-Qānūn fī aṭ-Ṭibb" (The Canon of Medicine) has been called the most famous single book in the history of medicine in both East and West. Avicenna excelled in the logical assessment of conditions and comparison of symptoms and took special note of analgesics and their proper use as well as other methods of relieving pain, including massage.

Avicenna was born in Afsanah at 980, a village near Bukhara. His father counted as ruler of a region by the name of keramaytan. Avicenna along with his family after moving to Bukhara, continued his studies. According to Nasr, Avicenna had many teachers including Nātelī physicians Abū Manṣūr Qomrī and Abū Sahl Masīḥī. Avicenna wrote nearly 250 works on diverse sciences in medieval period including long and short treatises such as the Daneshnameh Alaei (The Book of Science Dedicated to 'Alii' al-Dawlah). Avicenna wrote Isharat when he was under the criticism of certain literary scholars, showing his skill in Arabic language by a philosophy book as Isharat. Nasr refers to the book of Isharat as the last and greatest masterpiece of Avicenna.

Avicenna was born in Afshana, 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 Sitāra, was from Bukhara; his father, Abdullāh, was a respected Ismaili scholar from Balkh, an important town of the Samanid Empire, in what is today Balkh Province, Afghanistan. His father worked in the government of Samanid in the village Kharmasain, a Sunni regional power. After five years, his younger brother, Mahmoud, was born. Avicenna first began to learn the Quran and literature in such a way that when he was ten years old he had essentially learned all of them.

At 22 years old, Avicenna lost his father. The Samanid dynasty came to its end in December 1004. Avicenna seems to have declined the offers of Mahmud of Ghazni, and proceeded westwards to Urgench in modern Turkmenistan, where the vizier, regarded as a friend of scholars, gave him a small monthly stipend. The pay was small, however, so Ibn Sina wandered from place to place through the districts of Nishapur and Merv to the borders of Khorasan, seeking an opening for his talents. Qabus, the generous ruler of Tabaristan, himself a poet and a scholar, with whom Ibn Sina had expected to find asylum, was on about that date (1012) starved to death by his troops who had revolted. Avicenna himself was at this time stricken by a severe illness. Finally, at Gorgan, near the Caspian Sea, Avicenna met with a friend, who bought a dwelling near his own house in which Avicenna lectured on logic and astronomy. Several of his treatises were written for this patron; and the commencement of his "Canon of Medicine" also dates from his stay in Hyrcania.

While he was imprisoned in the castle of Fardajan near Hamadhan, Avicenna wrote his famous "Floating Man" – literally falling man – thought experiment to demonstrate human self-awareness and the substantiality and immateriality of the soul. Avicenna believed his "Floating Man" thought experiment demonstrated that the soul is a substance, and claimed humans cannot doubt their own consciousness, even in a situation that prevents all sensory data input. The thought experiment told its readers to imagine themselves created all at once while suspended in the air, isolated from all , which includes no sensory contact with even their own bodies. He argued that, in this scenario, one would still have self-consciousness. Because it is conceivable that a person, suspended in air while cut off from sense experience, would still be capable of determining his own existence, the thought experiment points to the conclusions that the soul is a perfection, independent of the body, and an immaterial substance. The conceivability of this "Floating Man" indicates that the soul is perceived intellectually, which entails the soul's separateness from the body. Avicenna referred to the living human intelligence, particularly the active intellect, which he believed to be the hypostasis by which God communicates truth to the human mind and imparts order and intelligibility to nature. Following is an English translation of the argument:

Avicenna was a devout Muslim and sought to reconcile rational philosophy with Islamic theology. His aim was to prove the existence of God and His creation of the world scientifically and through reason and logic. Avicenna's views on Islamic theology (and philosophy) were enormously influential, forming part of the core of the curriculum at Islamic religious schools until the 19th century. Avicenna wrote a number of short treatises dealing with Islamic theology. These included treatises on the prophets (whom he viewed as "inspired philosophers"), and also on various scientific and philosophical interpretations of the Quran, such as how Quranic cosmology corresponds to his own philosophical system. In general these treatises linked his philosophical writings to Islamic religious ideas; for example, the body's afterlife.

Contrary to Carl Brockelmann's information (GAL 1:485; Suppl. 1:887), Sharaf al-Zamān Muḥammad ibn ʿAlī al-Īlāqī of Bākharz (in Khorasān, Iran), who was most probably active in Balkh (today's Afghanistan), was not a figure of the 6th/12th century. He did not die in 536/1141 (in the battle of the Qatwan steppe) but most probably around 460/1068 and should be counted among Avicenna's (d. 429/1037) direct students. Al-Ilāqī produced an epitome of the first book of the Canons of Medicine by Avicenna which was known under various titles: "Kitāb al-Fuṣūl al-Ilāqiyya" ("The Aphorisms of al-Ilāqī") and "Kitāb al-asbāb wa-al-`alāmāt" ("The Book of Causes and Symptoms"). Al-Ilāqī's greatly abbreviated version of the first book of the Canon was very popular, and many copies have survived.

Avicenna's proof for the existence of God, known as the "Proof of the Truthful", was the first ontological argument, which he proposed in the "Metaphysics" section of "The Book of Healing". This was the first attempt at using the method of a priori proof, which utilizes intuition and reason alone. Avicenna's proof of God's existence is unique in that it can be classified as both a cosmological argument and an ontological argument. "It is ontological insofar as ‘necessary existence’ in intellect is the first basis for arguing for a Necessary Existent". The proof is also "cosmological insofar as most of it is taken up with arguing that contingent existents cannot stand alone and must end up in a Necessary Existent."

The Persian polymath Avicenna claimed to have observed Venus as a spot on the Sun. This is possible, as there was a transit on May 24, 1032, but Avicenna did not give the date of his observation, and modern scholars have questioned whether he could have observed the transit from his location at that time; he may have mistaken a sunspot for Venus. He used his transit observation to help establish that Venus was, at least sometimes, below the Sun in Ptolemaic cosmology, i.e. the sphere of Venus comes before the sphere of the Sun when moving out from the Earth in the prevailing geocentric model.

Avicenna Bay is a small bay lying southwest of D'Ursel Point along the east side of Brabant Island, in the Palmer Archipelago. It was roughly charted by the Belgian Antarctic Expedition under Adrien de Gerlache, 1897–99, photographed by Hunting Aerosurveys Ltd in 1956–57, and mapped from these photos in 1959. It was named by the UK Antarctic Place-Names Committee for Avicenna, greatest of the Persian school of physicians.
