Avicenna
Persian polymath, physician and philosopher (c. 980–1037)
Ibn Sina (; c. 980 – 22 June 1037), commonly known in the West as Avicenna (), was a preeminent philosopher and physician of the Muslim world, flourishing during the Islamic Golden Age, serving in the courts of various Iranian rulers. He is often described as the father of early modern medicine. His philosophy was of the Peripatetic school derived from Aristotelianism.
His most famous works are "The Book of Healing", a philosophical and scientific encyclopedia, and "The Canon of Medicine", a medical encyclopedia which became a standard medical text at many medieval European universities and remained in use as late as 1650. Besides philosophy and medicine, Avicenna's corpus includes writings on astronomy, alchemy, geography and geology, psychology, Islamic theology, logic, mathematics, physics, and works of poetry.
Avicenna wrote most of his philosophical and scientific works in Arabic, but also wrote several key works in Persian, while his poetic works were written in both languages. Of the 450 works he is believed to have written, around 240 have survived, including 150 on philosophy and 40 on medicine.
Name.
' is a Latin corruption of the Arabic patronym Ibn Sīnā (), meaning "Son of Sina". However, Avicenna was not the son but the great-great-grandson of a man named Sina. His formal Arabic name was Abū ʿAlī al-Ḥusayn bin ʿAbdullāh ibn al-Ḥasan bin ʿAlī bin Sīnā al-Balkhi al-Bukhari ().
Circumstances.
Avicenna created an extensive corpus of works during what is commonly known as the Islamic Golden Age, in which the translations of Byzantine, Greco-Roman, Persian, and Indian texts were studied extensively. Greco-Roman (Middle Platonic, Neoplatonic, and Aristotelian) texts translated 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 Empire 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 for cultural capital of the Muslim world. There, Avicenna had access to the great libraries of Balkh, Khwarazm, Gorgan, Rey, Isfahan and Hamadan.
Various texts (such as the 'Ahd with Bahmanyar) show that Avicenna debated philosophical points with the greatest scholars of the time. Nizami Aruzi described how before ibn Sina left Khwarazm, he had met al-Biruni (a scientist and astronomer), Abu Nasr Mansur (a renowned mathematician), Abu Sahl 'Isa ibn Yahya al-Masihi (a respected philosopher) and ibn al-Khammar (a great physician). The study of the Quran and the Hadith also thrived, and Islamic philosophy, fiqh "jurisprudence", and kalam "speculative theology" were all further developed by ibn Sina and his opponents at this time.
Biography.
Early life and education.
Avicenna was born in c. 980 in the village of Afshana in Transoxiana to a Persian family. The village was near the Samanid capital of Bukhara, which was his mother's hometown. His father Abd Allah was a native of the city of Balkh in Bactria. An official of the Samanid bureaucracy, he had served as the governor of a village of the royal estate of Harmaytan near Bukhara during the reign of Nuh II (r. 976 – 997). Avicenna also had a younger brother. A few years later, the family settled in Bukhara, a center of learning, which attracted many scholars. It was there that Avicenna was educated, which early on was seemingly administered by his father.
Although both Avicenna's father and brother had converted to Isma'ilism, he himself did not follow the faith. He was instead a Hanafi Sunni, the same school followed by the Samanids.
Avicenna was first schooled in the Quran and literature, and by the age of 10, he had memorized the entire Quran. He was later sent by his father to an Indian greengrocer, who taught him arithmetic. Afterwards, he was schooled in fiqh by the Hanafi jurist Ismail al-Zahid. Sometime later, his father invited the physician and philosopher al-Natili to their house to educate ibn Sina. Together, they studied the "Isagoge" of Porphyry (died 305) and possibly the "Categories" of Aristotle (died 322 BCE) as well. After Avicenna had read the "Almagest" of Ptolemy (died 170) and Euclid's "Elements", al-Natili told him to continue his research independently. By the time Avicenna was eighteen, he was well-educated in Greek sciences. Although ibn Sina only mentions al-Natili as his teacher in his autobiography, he most likely had other teachers as well, such as the physicians Qumri and Abu Sahl 'Isa ibn Yahya al-Masihi.
Career.
In Bukhara and Gurganj.
At the age of seventeen, Avicenna was made a physician of Nuh II. By the time Avicenna was at least 21 years old, his father died. He was subsequently given an administrative post, possibly succeeding his father as the governor of Harmaytan. Avicenna later moved to Gurganj, the capital of Khwarazm, which he reports that he did due to "necessity". The date he went to the place is uncertain, as he reports that he served the Khwarazmshah, the ruler of Khwarazm, the Ma'munid ruler Abu al-Hasan Ali. The latter ruled from 997 to 1009, which indicates that Avicenna moved sometime during that period.
He may have moved in 999, the year in which the Samanid Empire fell after the Kara-Khanid Khanate captured Bukhara and imprisoned the Samanid emir Abd al-Malik II. Due to his high position and strong connection with the Samanids, ibn Sina may have found himself in an unfavorable position after the fall of his suzerain.
It was through the minister of Gurganj, Abu'l-Husayn as-Sahi, a patron of Greek sciences, that Avicenna entered into the service of Abu al-Hasan Ali. Under the Ma'munids, Gurganj became a centre of learning, attracting many prominent figures, such as ibn Sina and his former teacher Abu Sahl al-Masihi, the mathematician Abu Nasr Mansur, the physician ibn al-Khammar, and the philologist al-Tha'alibi.
In Gorgan.
Avicenna later moved due to "necessity" once more (in 1012), this time to the west. There he travelled through the Khurasani cities of Nasa, Abivard, Tus, Samangan and Jajarm. He was planning to visit the ruler of the city of Gorgan, the Ziyarid Qabus (r. 977 – 981, 997 – 1012), a cultivated patron of writing, whose court attracted many distinguished poets and scholars. However, when Avicenna eventually arrived, he discovered that the ruler had been dead since the winter of 1013. Avicenna then left Gorgan for Dihistan, but returned after becoming ill. There he met Abu 'Ubayd al-Juzjani (died 1070) who became his pupil and companion. Avicenna stayed briefly in Gorgan, reportedly serving Qabus's son and successor Manuchihr (r. 1012 – 1031) and resided in the house of a patron.
In Ray and Hamadan.
In c. 1014, Avicenna went to the city of Ray, where he entered into the service of the Buyid amir Majd al-Dawla (r. 997 – 1029) and his mother Sayyida Shirin, the "de facto" ruler of the realm. There he served as the physician at the court, treating Majd al-Dawla, who was suffering from melancholia. Avicenna reportedly later served as the "business manager" of Sayyida Shirin in Qazvin and Hamadan, though details regarding this tenure are unclear. During this period, Avicenna finished writing "The Canon of Medicine" and started writing his "The Book of Healing".
In 1015, during Avicenna's stay in Hamadan, he participated in a public debate, as was customary for newly arrived scholars in western Iran at that time. The purpose of the debate was to examine one's reputation against a prominent resident. The person whom Avicenna debated against was Abu'l-Qasim al-Kirmani, a member of the school of philosophers of Baghdad. The debate became heated, resulting in ibn Sina accusing Abu'l-Qasim of lack of basic knowledge in logic, while Abu'l-Qasim accused ibn Sina of impoliteness.
After the debate, Avicenna sent a letter to the Baghdad Peripatetics, asking if Abu'l-Qasim's claim that he shared the same opinion as them was true. Abu'l-Qasim later retaliated by writing a letter to an unknown person in which he made accusations so serious that ibn Sina wrote to Abu Sa'd, the deputy of Majd al-Dawla, to investigate the matter. The accusation made towards Avicenna may have been the same as he had received earlier, in which he was accused by the people of Hamadan of copying the stylistic structures of the Quran in his "Sermons on Divine Unity". The seriousness of this charge, in the words of the historian Peter Adamson, "cannot be underestimated in the larger Muslim culture".
Not long afterwards, Avicenna shifted his allegiance to the rising Buyid amir Shams al-Dawla, the younger brother of Majd al-Dawla, which Adamson suggests was due to Abu'l-Qasim also working under Sayyida Shirin. Avicenna had been called upon by Shams al-Dawla to treat him, but after the latter's campaign in the same year against his former ally, the Annazid ruler Abu Shawk (r. 1010 – 1046), he forced Avicenna to become his vizier.
Although Avicenna would sometimes clash with Shams al-Dawla's troops, he remained vizier until the latter died of colic in 1021. Avicenna was asked to stay as vizier by Shams al-Dawla's son and successor Sama' al-Dawla (r. 1021 – 1023), but he instead went into hiding with his patron, Abu Ghalib al-Attar, to wait for better opportunities to emerge. It was during this period that Avicenna was secretly in contact with Ala al-Dawla Muhammad (r. 1008 – 1041), the Kakuyid ruler of Isfahan and uncle of Sayyida Shirin.
It was during his stay at Attar's home that Avicenna completed "The Book of Healing", writing 50 pages a day. The Buyid court in Hamadan, particularly the Kurdish vizier Taj al-Mulk, suspected Avicenna of correspondence with Ala al-Dawla, and as a result, had the house of Attar ransacked and ibn Sina imprisoned in the fortress of Fardajan, outside Hamadan. Juzjani blames one of ibn Sina's informers for his capture. He was imprisoned for four months until Ala al-Dawla captured Hamadan, ending Sama al-Dawla's reign.
In Isfahan.
Avicenna was subsequently released, and went to Isfahan, where he was well received by Ala al-Dawla. In the words of Juzjani, the Kakuyid ruler gave Avicenna "the respect and esteem which someone like him deserved". Adamson also says that Avicenna's service under Ala al-Dawla "proved to be the most stable period of his life". Avicenna served as the advisor, if not vizier of Ala al-Dawla, accompanying him in many of his military expeditions and travels. Avicenna dedicated two Persian works to him, a philosophical treatise named "Danish-nama-yi Ala'i" ("Book of Science for Ala"), and a medical treatise about the pulse.
During the brief occupation of Isfahan by the Ghaznavids in January 1030, Avicenna and Ala al-Dawla relocated to the southwestern Iranian region of Khuzistan, where they stayed until the death of the Ghaznavid ruler Mahmud (r. 998 – 1030), which occurred two months later. It was seemingly when Avicenna returned to Isfahan that he started writing his "Pointers and Reminders". In 1037, while Avicenna was accompanying Ala al-Dawla to a battle near Isfahan, he contracted a severe colic, having suffered from colic throughout his life. He died shortly afterwards in Hamadan, where he was buried.
Philosophy.
Avicenna wrote extensively on early Islamic philosophy, especially the subjects logic, ethics and metaphysics, including treatises named "Logic" and "Metaphysics". Most of his works were written in Arabic, then the language of science in the Muslim world, and some in Early New Persian. Of linguistic significance even to this day are a few books that he wrote in Persian, particularly the "Danishnama". Avicenna's commentaries on Aristotle often criticized the philosopher, encouraging a lively debate in the spirit of ijtihad.
Avicenna's Neoplatonic scheme of emanations became fundamental in kalam in the 12th century.
"The Book of Healing" became available in Europe in a partial Latin translation some fifty years after its composition under the title "Sufficientia", and some authors have identified a "Latin Avicennism" as flourishing for some time paralleling the more influential Latin Averroism, but it was suppressed by the Parisian decrees of 1210 and 1215.
Avicenna's psychology and theory of knowledge influenced the theologian William of Auvergne and Albertus Magnus, while his metaphysics influenced the thought of Thomas Aquinas.
Metaphysical doctrine.
Early Islamic philosophy and Islamic metaphysics, imbued as it is with kalam, distinguishes between essence and existence more clearly than Aristotelianism. Whereas existence is the domain of the contingent and the accidental, essence endures within a being beyond the accidental. The philosophy of Avicenna, particularly that part relating to metaphysics, owes much to al-Farabi. The search for a definitive Islamic philosophy separate from Occasionalism can be seen in what is left of his work.
Following al-Farabi's lead, Avicenna initiated a full-fledged inquiry into the question of being, in which he distinguished between essence () and existence (). He argued that the fact of existence cannot be inferred from or accounted for by the essence of existing things, and that form and matter by themselves cannot interact and originate the movement of the universe or the progressive actualization of existing things. Existence must, therefore, be due to an agent-cause that necessitates, imparts, gives, or adds existence to an essence. To do so, the cause must be an existing thing and coexist with its effect.
Impossibility, contingency, necessity.
Avicenna's consideration of the essence-attributes question may be elucidated in terms of his ontological analysis of the modalities of being; namely impossibility, contingency and necessity. Avicenna argued that the impossible being is that which cannot exist, while the contingent in itself ("mumkin bi-dhatihi") has the potentiality to be or not to be without entailing a contradiction. When actualized, the contingent becomes a 'necessary existent due to what is other than itself' ("wajib al-wujud bi-ghayrihi"). Thus, contingency-in-itself is potential beingness that could eventually be actualized by an external cause other than itself. The metaphysical structures of necessity and contingency are different. Necessary being due to itself ("wajib al-wujud bi-dhatihi") is true in itself, while the contingent being is 'false in itself' and 'true due to something else other than itself'. The necessary is the source of its own being without borrowed existence. It is what always exists.
Differentia.
The Necessary exists 'due-to-Its-Self', and has no quiddity/essence other than existence. Furthermore, It is 'One' ("wahid ahad") since there cannot be more than one 'Necessary-Existent-due-to-Itself' without differentia (fasl) to distinguish them from each other. Yet, to require differentia entails that they exist 'due-to-themselves' as well as 'due to what is other than themselves'; and this is contradictory. If no differentia distinguishes them from each other, then, in no sense are these 'Existents' not the same. Avicenna adds that the 'Necessary-Existent-due-to-Itself' has no genus ("jins"), nor a definition ("hadd"), nor a counterpart ("nadd"), nor an opposite ("did"), and is detached ("bari") from matter ("madda"), quality ("kayf"), quantity ("kam"), place ("ayn"), situation ("wad") and time ("waqt").
Reception.
Avicenna's theology on metaphysical issues ("ilāhiyyāt") has been criticized by some Islamic scholars, among them al-Ghazali, ibn Taymiyya, and ibn Qayyim al-Jawziyya. While discussing the views of the theists among the Greek philosophers, namely Socrates, Plato and Aristotle in "Al-Munqidh min ad-Dalal" "Deliverance from Error", al-Ghazali noted:
<templatestyles src="Template:Blockquote/styles.css" />[the Greek philosophers] must be taxed with unbelief, as must their partisans among the Muslim philosophers, such as Avicenna and al-Farabi and their likes. None, however, of the Muslim philosophers engaged so much in transmitting Aristotle's lore as did the two men just mentioned. [...] The sum of what we regard as the authentic philosophy of Aristotle, as transmitted by al-Farabi and Avicenna, can be reduced to three parts: a part which must be branded as unbelief; a part which must be stigmatized as innovation; and a part which need not be repudiated at all.
Argument for God's existence.
Avicenna made an argument for the existence of God which would be known as the "Proof of the Truthful" ("wajib al-wujud"). Avicenna argued that there must be a Proof of the Truthful, an entity that cannot "not" exist and through a series of arguments, he identified it with God in Islam. Present-day historian of philosophy Peter Adamson called this argument one of the most influential medieval arguments for God's existence, and Avicenna's biggest contribution to the history of philosophy.
Al-Biruni correspondence.
Correspondence between ibn Sina with his student Ahmad ibn ʿAli al-Maʿsumi and al-Biruni has survived in which they debated Aristotelian natural philosophy and the Peripatetic school. al-Biruni began by asking eighteen questions, ten of which were criticisms of Aristotle's "On the Heavens".
Theology.
Ibn Sina was a devout Muslim and sought to reconcile rational philosophy with Islamic theology. He aimed to prove the existence of God and His creation of the world scientifically and through reason and logic. His 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 several short treatises dealing with Islamic theology. These included treatises on the prophets and messengers in Islam, 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 philosophical system. In general, these treatises linked his philosophical writings to Islamic religious ideas; for example, the body's afterlife.
There are occasional brief hints and allusions in his longer works, however, that Avicenna considered philosophy as the only sensible way to distinguish real prophecy from illusion. He did not state this more clearly because of the political implications of such a theory if prophecy could be questioned, and also because most of the time he was writing shorter works which concentrated on explaining his theories on philosophy and theology clearly, without digressing to consider epistemological matters which could only be properly considered by other philosophers.
Later interpretations of Avicenna's philosophy split into three different schools; those (such as al-Tusi) who continued to apply his philosophy as a system to interpret later political events and scientific advances; those (such as al-Razi) who considered Avicenna's theological works in isolation from his wider philosophical concerns; and those (such as al-Ghazali) who selectively used parts of his philosophy to support their own attempts to gain greater spiritual insights through a variety of mystical means. It was the theological interpretation championed by those such as al-Razi which eventually came to predominate in the madrasahs.
Avicenna memorized the Quran by the age of ten, and as an adult, wrote five treatises commenting on surahs of the Quran. One of these texts included the "Proof of Prophecies", in which he comments on several Quranic verses and holds the Quran in high esteem. Avicenna argued that the Islamic prophets should be considered higher than philosophers.
Avicenna is generally understood to have been aligned with the Hanafi school of Sunni thought. Avicenna studied Hanafi law, many of his notable teachers were Hanafi jurists, and he served under the Hanafi court of Ali ibn Mamun. Avicenna said at an early age that he remained "unconvinced" by Ismaili missionary attempts to convert him.
Medieval historian Ẓahīr al-dīn al-Bayhaqī (d. 1169) believed Avicenna to be a follower of the Brethren of Purity.
Thought experiments.
While he was imprisoned in the castle of Fardajan near Hamadhan, Avicenna wrote his famous "floating man"—literally falling man—a 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:
<templatestyles src="Template:Blockquote/styles.css" />One of us (i.e. a human being) should be imagined as having been created in a single stroke; created perfect and complete but with his vision obscured so that he cannot perceive external entities; created falling through air or a void, in such a manner that he is not struck by the firmness of the air in any way that compels him to feel it, and with his limbs separated so that they do not come in contact with or touch each other. Then contemplate the following: can he be assured of the existence of himself? He does not have any doubt in that his self exists, without thereby asserting that he has any exterior limbs, nor any internal organs, neither heart nor brain, nor any one of the exterior things at all; but rather he can affirm the existence of himself, without thereby asserting there that this self has any extension in space. Even if it were possible for him in that state to imagine a hand or any other limb, he would not imagine it as being a part of his self, nor as a condition for the existence of that self; for as you know that which is asserted is different from that which is not asserted and that which is inferred is different from that which is not inferred. Therefore the self, the existence of which has been asserted, is a unique characteristic, in as much that it is not as such the same as the body or the limbs, which have not been ascertained. Thus that which is ascertained (i.e. the self), does have a way of being sure of the existence of the soul as something other than the body, even something non-bodily; this he knows, this he should understand intuitively, if it is that he is ignorant of it and needs to be beaten with a stick [to realize it].
However, Avicenna posited the brain as the place where reason interacts with sensation. Sensation prepares the soul to receive rational concepts from the universal Agent Intellect. The first knowledge of the flying person would be "I am," affirming his or her essence. That essence could not be the body, obviously, as the flying person has no sensation. Thus, the knowledge that "I am" is the core of a human being: the soul exists and is self-aware. Avicenna thus concluded that the idea of the self is not logically dependent on any physical thing, and that the soul should not be seen in relative terms, but as a primary given, a substance. The body is unnecessary; in relation to it, the soul is its perfection. In itself, the soul is an immaterial substance.
Principal works.
"The Canon of Medicine".
Avicenna authored a five-volume medical encyclopedia, "The Canon of Medicine" (). It was used as the standard medical textbook in the Islamic world and Europe up to the 18th century. The "Canon" still plays an important role in Unani medicine.
"Liber Primus Naturalium".
Avicenna considered whether events like rare diseases or disorders have natural causes. He used the example of polydactyly to explain his perception that causal reasons exist for all medical events. This view of medical phenomena anticipated developments in the Enlightenment by seven centuries.
"The Book of Healing".
Earth sciences.
Avicenna wrote on Earth sciences such as geology in "The Book of Healing". While discussing the formation of mountains, he explained:
<templatestyles src="Template:Blockquote/styles.css" />
Philosophy of science.
In the "Al-Burhan" ("On Demonstration") section of "The Book of Healing", Avicenna discussed the philosophy of science and described an early scientific method of inquiry. He discussed Aristotle's "Posterior Analytics" and significantly diverged from it on several points. Avicenna discussed the issue of a proper methodology for scientific inquiry and the question of "How does one acquire the first principles of a science?" He asked how a scientist would arrive at "the initial axioms or hypotheses of a deductive science without inferring them from some more basic premises?" He explained that the ideal situation is when one grasps that a "relation holds between the terms, which would allow for absolute, universal certainty". Avicenna then added two further methods for arriving at the first principles: the ancient Aristotelian method of induction ("istiqra"), and the method of examination and experimentation ("tajriba"). Avicenna criticized Aristotelian induction, arguing that "it does not lead to the absolute, universal, and certain premises that it purports to provide." In its place, he developed a "method of experimentation as a means for scientific inquiry."
Logic.
An early formal system of temporal logic was studied by Avicenna. Although he did not develop a real theory of temporal propositions, he did study the relationship between "temporalis" and the implication. Avicenna's work was further developed by Najm al-Dīn al-Qazwīnī al-Kātibī and became the dominant system of Islamic logic until modern times. Avicennian logic also influenced several early European logicians such as Albertus Magnus and William of Ockham. Avicenna endorsed the law of non-contradiction proposed by Aristotle, that a fact could not be both true and false at the same time and in the same sense of the terminology used. He stated, "Anyone who denies the law of non-contradiction should be beaten and burned until he admits that to be beaten is not the same as not to be beaten, and to be burned is not the same as not to be burned."
Physics.
In mechanics, Avicenna, in "The Book of Healing", developed a theory of motion, in which he made a distinction between the inclination (tendency to motion) and force of a projectile, and concluded that motion was a result of an inclination ("mayl") transferred to the projectile by the thrower, and that projectile motion in a vacuum would not cease. He viewed inclination as a permanent force whose effect is dissipated by external forces such as air resistance.
The theory of motion presented by Avicenna was probably influenced by the 6th-century Alexandrian scholar John Philoponus. Avicenna's is a less sophisticated variant of the theory of impetus developed by Buridan in the 14th century. It is unclear if Buridan was influenced by Avicenna, or by Philoponus directly.
In optics, Avicenna was among those who argued that light had a speed, observing that "if the perception of light is due to the emission of some sort of particles by a luminous source, the speed of light must be finite." He also provided a wrong explanation of the rainbow phenomenon. Carl Benjamin Boyer described Avicenna's ("Ibn Sīnā") theory on the rainbow as follows:
<templatestyles src="Template:Blockquote/styles.css" />Independent observation had demonstrated to him that the bow is not formed in the dark cloud but rather in the very thin mist lying between the cloud and the sun or observer. The cloud, he thought, serves as the background of this thin substance, much as a quicksilver lining is placed upon the rear surface of the glass in a mirror. Ibn Sīnā would change the place not only of the bow, but also of the color formation, holding the iridescence to be merely a subjective sensation in the eye.
In 1253, a Latin text entitled "Speculum Tripartitum" stated the following regarding Avicenna's theory on heat:
<templatestyles src="Template:Blockquote/styles.css" />Avicenna says in his book of heaven and earth, that heat is generated from motion in external things.
Psychology.
Avicenna's legacy in classical psychology is primarily embodied in the "Kitab al-nafs" parts of his "Kitab al-shifa" ("The Book of Healing") and "Kitab al-najat" ("The Book of Deliverance"). These were known in Latin under the title De Anima (treatises "on the soul"). Notably, Avicenna develops what is called the Flying Man argument in the Psychology of "The Cure" I.1.7 as defence of the argument that the soul is without quantitative extension, which has an affinity with Descartes's "cogito" argument (or what phenomenology designates as a form of an "epoche").
Avicenna's psychology requires that connection between the body and soul be strong enough to ensure the soul's individuation, but weak enough to allow for its immortality. Avicenna grounds his psychology on physiology, which means his account of the soul is one that deals almost entirely with the natural science of the body and its abilities of perception. Thus, the philosopher's connection between the soul and body is explained almost entirely by his understanding of perception; in this way, bodily perception interrelates with the immaterial human intellect. In sense perception, the perceiver senses the form of the object; first, by perceiving features of the object by our external senses. This sensory information is supplied to the internal senses, which merge all the pieces into a whole, unified conscious experience. This process of perception and abstraction is the nexus of the soul and body, for the material body may only perceive material objects, while the immaterial soul may only receive the immaterial, universal forms. The way the soul and body interact in the final abstraction of the universal from the concrete particular is the key to their relationship and interaction, which takes place in the physical body.
The soul completes the action of intellection by accepting forms that have been abstracted from matter. This process requires a concrete particular (material) to be abstracted into the universal intelligible (immaterial). The material and immaterial interact through the Active Intellect, which is a "divine light" containing the intelligible forms. The Active Intellect reveals the universals concealed in material objects much like the sun makes colour available to our eyes.
Other contributions.
Astronomy and astrology.
Avicenna wrote an attack on astrology titled "Missive on the Champions of the Rule of the Stars" () in which he cited passages from the Quran to dispute the power of astrology to foretell the future. He believed that each classical planet had some influence on the Earth but argued against current astrological practices.
Avicenna's astronomical writings had some influence on later writers, although in general his work could be considered less developed than that of ibn al-Haytham or al-Biruni. One important feature of his writing is that he considers mathematical astronomy a separate discipline from astrology. He criticized Aristotle's view of the stars receiving their light from the Sun, stating that the stars are self-luminous, and believed that the planets are also self-luminous. He claimed to have observed the transit of Venus. This is possible as there was a transit on 24 May 1032, but ibn Sina 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 the geocentric model, i.e. the sphere of Venus comes before the sphere of the Sun when moving out from the Earth.
He also wrote the "Summary of the Almagest" based on Ptolemy's "Almagest" with an appended treatise "to bring that which is stated in the Almagest and what is understood from Natural Science into conformity". For example, ibn Sina considers the motion of the solar apsis, which Ptolemy had taken to be fixed.
Chemistry.
Avicenna was first to derive the attar of flowers from distillation and used steam distillation to produce essential oils such as rose essence, which he used as aromatherapeutic treatments for heart conditions.
Unlike al-Razi, Avicenna explicitly disputed the theory of the transmutation of substances commonly believed by alchemists:
<templatestyles src="Template:Blockquote/styles.css" />Those of the chemical craft know well that no change can be effected in the different species of substances, though they can produce the appearance of such change.
Four works on alchemy attributed to Avicenna were translated into Latin as:
 was the most influential, having influenced later medieval chemists and alchemists such as Vincent of Beauvais. However, Anawati argues (following Ruska) that the de Anima is a fake by a Spanish author. Similarly the Declaratio is believed not to be actually by Avicenna. The third work ("The Book of Minerals") is agreed to be Avicenna's writing, adapted from the "Kitab al-Shifa" ("Book of the Remedy"). Avicenna classified minerals into stones, fusible substances, sulfurs and salts, building on the ideas of Aristotle and Jabir. The "epistola de Re recta" is somewhat less sceptical of alchemy; Anawati argues that it is by Avicenna, but written earlier in his career when he had not yet firmly decided that transmutation was impossible.
Poetry.
Almost half of Avicenna's works are versified. His poems appear in both Arabic and Persian. As an example, Edward Granville Browne claims that the following Persian verses are incorrectly attributed to Omar Khayyám, and were originally written by Ibn Sīnā:

Robert Wisnovsky, a scholar of Avicenna attached to McGill University, says that "Avicenna was the central figure in the long history of the rational sciences in Islam, particularly in the fields of metaphysics, logic and medicine" but that his works didn't only have an influence in these "secular" fields of knowledge alone, as "these works, or portions of them, were read, taught, copied, commented upon, quoted, paraphrased and cited by thousands of post-Avicennian scholars—not only philosophers, logicians, physicians and specialists in the mathematical or exact sciences, but also by those who specialized in the disciplines of ʿilm al-kalām (rational theology, but understood to include natural philosophy, epistemology and philosophy of mind) and usūl al-fiqh (jurisprudence, but understood to include philosophy of law, dialectic, and philosophy of language)."
Medieval and Renaissance Europe.
As early as the 14th century when Dante Alighieri depicted him in Limbo alongside the virtuous non-Christian thinkers in his "Divine Comedy" such as Virgil, Averroes, Homer, Horace, Ovid, Lucan, Socrates, Plato and Saladin. Avicenna has been recognized by both East and West as one of the great figures in intellectual history. Johannes Kepler cites Avicenna's opinion when discussing the causes of planetary motions in Chapter 2 of "Astronomia Nova".
George Sarton, the author of "The History of Science", described Avicenna as "one of the greatest thinkers and medical scholars in history" and called him "the most famous scientist of Islam and one of the most famous of all races, places, and times". He was one of the Islamic world's leading writers in the field of medicine.
Along with Rhazes, Abulcasis, Ibn al-Nafis and al-Ibadi, Avicenna is considered an important compiler of early Muslim medicine. He is remembered in the Western history of medicine as a major historical figure who made important contributions to medicine and the European Renaissance. His medical texts were unusual in that where controversy existed between Galen and Aristotle's views on medical matters (such as anatomy), he preferred to side with Aristotle, where necessary updating Aristotle's position to take into account post-Aristotelian advances in anatomical knowledge. Aristotle's dominant intellectual influence among medieval European scholars meant that Avicenna's linking of Galen's medical writings with Aristotle's philosophical writings in the "Canon of Medicine" (along with its comprehensive and logical organisation of knowledge) significantly increased Avicenna's importance in medieval Europe in comparison to other Islamic writers on medicine. His influence following translation of the "Canon" was such that from the early fourteenth to the mid-sixteenth centuries he was ranked with Hippocrates and Galen as one of the acknowledged authorities, ("prince of physicians").
Modern reception.
Institutions in a variety of counties have been named after Avicenna in honour of his scientific accomplishments, including the Avicenna Mausoleum and Museum, Bu-Ali Sina University, Avicenna Research Institute and Ibn Sina Academy of Medieval Medicine and Sciences. There is also a crater on the Moon named Avicenna.
The Avicenna Prize, established in 2003, is awarded every two years by UNESCO and rewards individuals and groups for their achievements in the field of ethics in science.
The Avicenna Directories (2008–15; now the World Directory of Medical Schools) list universities and schools where doctors, public health practitioners, pharmacists and others, are educated. The original project team stated: <templatestyles src="Template:Blockquote/styles.css" />Why Avicenna? Avicenna ... was ... noted for his synthesis of knowledge from both east and west. He has had a lasting influence on the development of medicine and health sciences. The use of Avicenna's name symbolises the worldwide partnership that is needed for the promotion of health services of high quality.
In June 2009, Iran donated a "Persian Scholars Pavilion" to the United Nations Office in Vienna. It now sits in the Vienna International Center.
In popular culture.
The 1982 Soviet film "Youth of Genius" () by Elyor Ishmukhamedov recounts Avicenna's younger years. The film is set in Bukhara at the turn of the millennium.
In Louis L'Amour's 1985 historical novel "The Walking Drum", Kerbouchard studies and discusses Avicenna's "The Canon of Medicine".
In his book "The Physician" (1988) Noah Gordon tells the story of a young English medical apprentice who disguises himself as a Jew to travel from England to Persia and learn from Avicenna, the great master of his time. The novel was adapted into a feature film, "The Physician", in 2013. Avicenna was played by Ben Kingsley.
List of works.
The treatises of Avicenna influenced later Muslim thinkers in many areas including theology, philology, mathematics, astronomy, physics and music. His works numbered almost 450 volumes on a wide range of subjects, of which around 240 have survived. In particular, 150 volumes of his surviving works concentrate on philosophy and 40 of them concentrate on medicine. His most famous works are "The Book of Healing", and "The Canon of Medicine".
Avicenna wrote at least one treatise on alchemy, but several others have been falsely attributed to him. His "Logic", "Metaphysics", "Physics", and "De Caelo", are treatises giving a synoptic view of Aristotelian doctrine, though "Metaphysics" demonstrates a significant departure from the brand of Neoplatonism known as Aristotelianism in Avicenna's world; Arabic philosophers have hinted at the idea that Avicenna was attempting to "re-Aristotelianise" Muslim philosophy in its entirety, unlike his predecessors, who accepted the conflation of Platonic, Aristotelian, Neo- and Middle-Platonic works transmitted into the Muslim world.
The "Logic" and "Metaphysics" have been extensively reprinted, the latter, e.g., at Venice in 1493, 1495 and 1546. Some of his shorter essays on medicine, logic, etc., take a poetical form (the poem on logic was published by Schmoelders in 1836). Two encyclopedic treatises, dealing with philosophy, are often mentioned. The larger, "Al-Shifa'" ("Sanatio"), exists nearly complete in manuscript in the Bodleian Library and elsewhere; part of it on the "De Anima" appeared at Pavia (1490) as the "Liber Sextus Naturalium", and the long account of Avicenna's philosophy given by Muhammad al-Shahrastani seems to be mainly an analysis, and in many places a reproduction, of the Al-Shifa'. A shorter form of the work is known as the An-najat ("Liberatio"). The Latin editions of part of these works have been modified by the corrections which the monastic editors confess that they applied. There is also a ("hikmat-al-mashriqqiyya", in Latin "Philosophia Orientalis"), mentioned by Roger Bacon, the majority of which is lost in antiquity, which according to Averroes was pantheistic in tone.
Avicenna's works further include:
Persian works.
Avicenna's most important Persian work is the "Danishnama" (, "Book of Knowledge". Avicenna created a new scientific vocabulary that had not previously existed in Persian. The "Danishnama" covers such topics as logic, metaphysics, music theory and other sciences of his time. It has been translated into English by Parwiz Morewedge in 1977. The book is also important in respect to Persian scientific works.
"Andar Dānish-i Rag" (, "On the Science of the Pulse") contains nine chapters on the science of the pulse and is a condensed synopsis.
Persian poetry from Avicenna is recorded in various manuscripts and later anthologies such as "Nozhat al-Majales".

 This is, on the whole, an informed and good account of the life and accomplishments of one of the greatest influences on the development of thought both Eastern and Western. ... It is not as philosophically thorough as the works of D. Saliba, A.M. Goichon, or L. Gardet, but it is probably the best essay in English on this important thinker of the Middle Ages. (Julius R. Weinberg, "The Philosophical Review", Vol. 69, No. 2, Apr. 1960, pp. 255–259)
 This is a distinguished work which stands out from, and above, many of the books and articles which have been written in this century on Avicenna (Ibn Sīnā) (980–1037). It has two main features on which its distinction as a major contribution to Avicennan studies may be said to rest: the first is its clarity and readability; the second is the comparative approach adopted by the author. ...

Muslim world
Muslim-majority countries, states, districts, or towns
The terms Muslim world and Islamic world () commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs, politics, and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense.
The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology during the Islamic Golden Age. Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam. The Islamic conquests, which culminated in the Caliphate being established across three continents (Asia, Africa, and Europe), enriched the Muslim world, achieving the economic preconditions for the emergence of this institution owing to the emphasis attached to Islamic teachings. In the modern era, most of the Muslim world came under European colonial domination. The nation states that emerged in the post-colonial era have adopted a variety of political and economic models, and they have been affected by secular as well as religious trends.
As of 2013[ [update]], the combined GDP (nominal) of 50 Muslim majority countries was US$5.7 trillion. As of 2016[ [update]], they contributed 8% of the world's total. In 2020, the Economy of the Organisation of Islamic Cooperation which consists of 57 member states had a combined GDP(PPP) of US$ 24 trillion which is equal to about 18% of world's GDP or US$ 30 trillion with 5 OIC observer states which is equal to about 22% of the world's GDP. Some OIC member countries -Ivory Coast, Guyana, Gabon, Mozambique, Nigeria, Suriname, Togo and Uganda are not Muslim-majority.
As of 2020, 1.8 billion or more than 25% of the world population are Muslims. By the percentage of the total population in a region considering themselves Muslim, 91% in the Middle East-North Africa (MENA), 89% in Central Asia, 40% in Southeast Asia, 31% in South Asia, 30% in Sub-Saharan Africa, 25% in Asia, 1.4% in Oceania, 6% in Europe, and 1% in the Americas.
Most Muslims are of one of two denominations: Sunni Islam (87–90%) and Shia (10–13%). However, other denominations exist in pockets, such as Ibadi (primarily in Oman). Muslims who do not belong to, do not self-identify with, or cannot be readily classified under one of the identifiable Islamic schools and branches are known as non-denominational Muslims. About 13% of Muslims live in Indonesia, the largest Muslim-majority country; % of Muslims live in South Asia, the largest population of Muslims in the world; % in the Middle East–North Africa, where it is the dominant religion; and 15% in Sub-Saharan Africa and West Africa (primarily in Nigeria). Muslims are the overwhelming majority in Central Asia, the majority in the Caucasus, and widespread in Southeast Asia. India has the largest Muslim population outside Muslim-majority countries. Pakistan, Bangladesh, Iran, and Egypt are home to the world’s second, fourth, sixth and seventh largest Muslim populations respectively. Sizeable Muslim communities are also found in the Americas, Russia, India, China, and Europe. Islam is the fastest-growing major religion in the world partially due to their high birth rate, according to the same study, religious switching has no impact on Muslim population, since the number of people who embrace Islam and those who leave Islam are roughly equal. China has the third largest Muslim population outside Muslim-majority countries, while Russia has the fifth largest Muslim population. Nigeria has the largest Muslim population in Africa, while Indonesia has the largest Muslim population in Asia.
Terminology.
The term has been documented as early as 1912 to encompass the influence of perceived pan-Islamic propaganda. "The Times" described Pan-Islamism as a movement with power, importance, and cohesion born in Paris, where Turks, Arabs and Persians congregated. The correspondent's focus was on India: it would take too long to consider the progress made in various parts of the Muslim world. The article considered the position of the Amir, the effect of the Tripoli Campaign, Anglo-Russian action in Persia, and "Afghan Ambitions".
In a modern geopolitical sense, the terms 'Muslim world' and 'Islamic world' refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. Some scholars and commentators have criticised the term 'Muslim/Islamic world' and its derivative terms 'Muslim/Islamic country' as "simplistic" and "binary", since no state has a religiously homogeneous population (e.g. Egypt's citizens are c. 10% Christians), and in absolute numbers, there are sometimes fewer Muslims living in countries in which they make up the majority than in countries in which they form a minority. Moreover, the idea of a uniform Muslim world is imagined. Emerging in popular discourse in the nineteenth century, imperialists used the term to emphasize the civilizational differences between east and west. In opposition to colonization some Muslims started using the term in attempts at providing a unified front against western imperialism. Hence, the term 'Muslim-majority countries' is often preferred in literature.
History.
The history of the Islamic faith as a religion and social institution begins with its inception around 610 CE, when the Islamic prophet Muhammad, a native of Mecca, is believed by Muslims to have received the first revelation of the Quran, and began to preach his message. In 622 CE, facing opposition in Mecca, he and his followers migrated to Yathrib (now Medina), where he was invited to establish a new constitution for the city under his leadership. This migration, called the Hijra, marks the first year of the Islamic calendar. By the time of his death, Muhammad had become the political and spiritual leader of Medina, Mecca, the surrounding region, and numerous other tribes in the Arabian Peninsula.
After Muhammad died in 632, his successors (the Caliphs) continued to lead the Muslim community based on his teachings and guidelines of the Quran. The majority of Muslims consider the first four successors to be 'rightly guided' or Rashidun. The conquests of the Rashidun Caliphate helped to spread Islam beyond the Arabian Peninsula, stretching from northwest India, across Central Asia, the Near East, North Africa, southern Italy, and the Iberian Peninsula, to the Pyrenees. The Arab Muslims were unable to conquer the entire Christian Byzantine Empire in Asia Minor during the Arab–Byzantine wars, however. The succeeding Umayyad Caliphate attempted two failed sieges of Constantinople in 674–678 and 717–718. Meanwhile, the Muslim community tore itself apart into the rivalling Sunni and Shia sects since the killing of caliph Uthman in 656, resulting in a succession crisis that has never been resolved. The following First, Second and Third Fitnas and finally the Abbasid Revolution (746–750) also definitively destroyed the political unity of the Muslims, who have been inhabiting multiple states ever since. Ghaznavids' rule was succeeded by the Ghurid Empire of Muhammad of Ghor and Ghiyath al-Din Muhammad, whose reigns under the leadership of Muhammad Bakhtiyar Khalji extended until the Bengal, where South Asian Islamic missionaries achieved their greatest success in terms of dawah and number of converts to Islam. Qutb ud-Din Aibak conquered Delhi in 1206 and began the reign of the Delhi Sultanate, a successive series of dynasties that synthesized Indian civilization with the wider commercial and cultural networks of Africa and Eurasia, greatly increased demographic and economic growth in India and deterred Mongol incursion into the prosperous Indo-Gangetic Plain and enthroned one of the few female Muslim rulers, Razia Sultana.
Notable major empires dominated by Muslims, such as those of the Abbasids, Fatimids, Almoravids, Gao Empire, Seljukids, largest contiguous Songhai Empire (15th-16th centuries) of Sahel, West Africa, southern North Africa and western Central Africa which dominated the centers of Islamic knowledge of Timbuktu, Djenne, Oualata and Gao, Ajuran, Adal and Warsangali in Somalia, Mughals in the Indian subcontinent (India, Bangladesh, Pakistan, etc.), Safavids in Persia and Ottomans in Anatolia, Massina Empire, Sokoto Caliphate of northern Nigeria, Toucouleur Empire, were among the influential and distinguished powers in the world. 19th-century colonialism and 20th-century decolonisation have resulted in several independent Muslim-majority states around the world, with vastly differing attitudes towards and political influences granted to, or restricted for, Islam from country to country. These have revolved around the question of Islam's compatibility with other ideological concepts such as secularism, nationalism (especially Arab nationalism and Pan-Arabism, as opposed to Pan-Islamism), socialism (see also Arab socialism and socialism in Iran), democracy (see Islamic democracy), republicanism (see also Islamic republic), liberalism and progressivism, feminism, capitalism and more.
Gunpowder empires.
Scholars often use the term Age of the Islamic Gunpowders to describe period the Safavid, Ottoman and Mughal states. Each of these three empires had considerable military exploits using the newly developed firearms, especially cannon and small arms, to create their empires. They existed primarily between the fourteenth and the late seventeenth centuries. During the 17th–18th centuries, when the Indian subcontinent was ruled by Mughal Empire's sixth ruler Muhammad Auranzgeb through sharia and Islamic economics, India became the world's largest economy, valued 25% of world GDP.
Great Divergence.
<templatestyles src="Template:Quote_box/styles.css" />
"Why do the Christian nations, which were so weak in the past compared with Muslim nations begin to dominate so many lands in modern times and even defeat the once victorious Ottoman armies?"..."Because they have laws and rules invented by reason."
Ibrahim Muteferrika, "Rational basis for the Politics of Nations" (1731)
The Great Divergence was the reason why European colonial powers militarily defeated preexisting Oriental powers like the Mughal Empire, starting from the wealthy Bengal Subah, Tipu Sultan's Kingdom of Mysore, the Ottoman Empire and many smaller states in the pre-modern Greater Middle East, and initiated a period known as 'colonialism'.
Colonialism.
Beginning with the 15th century, colonialism by European powers profoundly affected Muslim-majority societies in Africa, Europe, the Middle East and Asia. Colonialism was often advanced by conflict with mercantile initiatives by colonial powers and caused tremendous social upheavals in Muslim-dominated societies.
A number of Muslim-majority societies reacted to Western powers with zealotry and thus initiating the rise of Pan-Islamism; or affirmed more traditionalist and inclusive cultural ideals; and in rare cases adopted modernity that was ushered by the colonial powers.
The only Muslim-majority regions not to be colonized by the Europeans were Saudi Arabia, Iran, Turkey, and Afghanistan. Turkey was one of the first colonial powers of the world with the Ottoman empire ruling several states for over 6 centuries.
Postcolonial era.
In the 20th century, the end of the European colonial domination has led to creation of a number of nation states with significant Muslim populations. These states drew on Islamic traditions to varying degree and in various ways in organizing their legal, educational and economic systems. The Times first documented the term "Muslim world" in 1912 when describing Pan-Islamism as a movement with power importance and cohesion born in Paris where Turks, Arabs and Persians congregated. The article considered The position of the Amir; the effect of the Tripoli Campaign; Anglo-Russian action in Persia; and "Afghan Ambitions".
A significant change in the Muslim world was the defeat and dissolution of the Ottoman Empire (1908–1922), to which the Ottoman officer and Turkish revolutionary statesman Mustafa Kemal Atatürk had an instrumental role in ending and replacing it with the Republic of Turkey, a modern, secular democracy (see Abolition of the Ottoman sultanate). The secular values of Kemalist Turkey, which separated religion from the state with the abolition of the Caliphate in 1924, have sometimes been seen as the result of Western influence.
In the 21st century, after the September 11 attacks (2001) coordinated by the Wahhabi Islamist terrorist group Al-Qaeda against the United States, scholars considered the ramifications of seeking to understand Muslim experience through the framework of secular Enlightenment principles. Muhammad Atta, one of the 11 September hijackers, reportedly quoted from the Quran to allay his fears: "Fight them, and God will chastise them at your hands/And degrade them, and He will help you/Against them, and bring healing to the breasts of a people who believe", referring to the "ummah", the community of Muslim believers, and invoking the imagery of the early warriors of Islam who lead the faithful from the darkness of "jahiliyyah".
By Sayyid Qutb's definition of Islam, the faith is "a complete divorce from jahiliyyah". He complained that American churches served as centers of community social life that were "very hard [to] distinguish from places of fun and amusement". For Qutb, Western society was the modern "jahliliyyah". His understanding of the "Muslim world" and its "social order" was that, presented to the Western world as the result of practicing Islamic teachings, would impress "by the beauty and charm of true Islamic ideology". He argued that the values of the Enlightenment and its related precursor, the Scientific Revolution, "denies or suspends God's sovereignty on earth" and argued that strengthening "Islamic character"
was needed "to abolish the negative influences of "jahili" life."
Islam by country.
As the Muslim world came into contact with secular ideals, societies responded in different ways. Some Muslim-majority countries are secular. Azerbaijan became the first secular republic in the Muslim world, between 1918 and 1920, before it was incorporated into the Soviet Union. Turkey has been governed as a secular state since the reforms of Mustafa Kemal Atatürk. By contrast, the 1979 Iranian Revolution replaced a monarchial semi-secular regime with an Islamic republic led by the Ayatollah, Ruhollah Khomeini.
Some countries have declared Islam as the official state religion. In those countries, the legal code is largely secular. Only personal status matters pertaining to inheritance and marriage are governed by Sharia law. In some places, Muslims implement Islamic law, called sharia in Arabic. The Islamic law exists in a number of variations, called schools of jurisprudence. The Amman Message, which was endorsed in 2005 by prominent Islamic scholars around the world, recognized four Sunni schools (Hanafi, Maliki, Shafi'i, Hanbali), two Shia schools (Ja'fari, Zaidi), the Ibadi school, and the Zahiri school.

Muslim-minority states.
According to the Pew Research Center in 2015 there were 50 Muslim-majority countries, which are shown in the Government and religion section above in the article. Apart from these, large Muslim populations exist in some countries where Muslims are a minority, and their Muslim communities are larger than many Muslim-majority nations:
Politics.
During much of the 20th century, the Islamic identity and the dominance of Islam on political issues have arguably increased during the early 21st century. The fast-growing interests of the Western world in Islamic regions, international conflicts and globalization have changed the influence of Islam on the world in contemporary history.
Demographics.
More than 24.1% of the world's population is Muslim, with an estimated total of approximately 1.9 billion. Muslims are the majority in 49 countries, they speak hundreds of languages and come from diverse ethnic backgrounds. The city of Karachi has the largest Muslim population in the world.
Geography.
Because the terms 'Muslim world' and 'Islamic world' are disputed, since no country is homogeneously Muslim, and there is no way to determine at what point a Muslim minority in a country is to be considered 'significant' enough, there is no consensus on how to define the Muslim world geographically. The only rule of thumb for inclusion which has some support, is that countries need to have a Muslim population of more than 50%.
In 2010, 73% of the world's Muslim population lived in countries where Muslims are in the majority, while 27% of the world's Muslim population lived in countries where Muslims are in the minority. India's Muslim population is the world's largest Muslim-minority population in the world (11% of the world's Muslim population). Jones (2005) defines a "large minority" as being between 30% and 50%, which described nine countries in 2000, namely Eritrea, Ethiopia, Guinea-Bissau, Ivory Coast, Nigeria, North Macedonia, and Tanzania. As of 2024, however, Nigeria has become a Muslim-majority country.
Religion.
Islam.
The two main denominations of Islam are the Sunni and Shia sects. They differ primarily upon of how the life of the ummah ("faithful") should be governed, and the role of the imam. Sunnis believe that the true political successor of Muhammad according to the Sunnah should be selected based on ٍShura (consultation), as was done at the Saqifah which selected Abu Bakr, Muhammad's father-in-law, to be Muhammad's political but not his religious successor. Shia, on the other hand, believe that Muhammad designated his son-in-law Ali ibn Abi Talib as his true political as well as religious successor.
The overwhelming majority of Muslims in the world, between 87 and 90%, are Sunni. Shias and other groups make up the rest, about 10–13% of overall Muslim population. The countries with the highest concentration of Shia populations are: Iran – 89%, Azerbaijan – 65%, Iraq – 60%, Bahrain – 60%, Yemen – 35%, Turkey – 10%, Lebanon – 27%, Syria – 13%, Afghanistan – 10%, Pakistan – 10%, and India – 10%.
Non-denominational Muslims make up a majority of the Muslims in seven countries (and a plurality in three others): Albania (65%), Kyrgyzstan (64%), Kosovo (58%), Indonesia (56%), Mali (55%), Bosnia and Herzegovina (54%), Uzbekistan (54%), Azerbaijan (45%), Russia (45%), and Nigeria (42%). They are found primarily in Central Asia. Kazakhstan has the largest number of non-denominational Muslims, who constitute about 74% of the population. Southeastern Europe also has a large number of non-denominational Muslims.
The Kharijite Muslims, who are less known, have their own stronghold in the country of Oman holding about 75% of the population.
Islamic schools and branches.
The first centuries of Islam gave rise to three major sects: Sunnis, Shi'as and Kharijites. Each sect developed distinct jurisprudence schools ("madhhab") reflecting different methodologies of jurisprudence ("fiqh").
The major Sunni madhhabs are Hanafi, Maliki, Shafi'i, and Hanbali.
The major Shi'a branches are Twelver (Imami), Ismaili (Sevener) and Zaidi (Fiver). Isma'ilism later split into Nizari Ismaili and Musta’li Ismaili, and then Mustaali was divided into Hafizi and Taiyabi Ismailis. It also gave rise to the Qarmatian movement and the Druze faith, although Druzes do not identify as Muslims. Twelver Shiism developed Ja'fari jurisprudence whose branches are Akhbarism and Usulism, and other movements such as Alawites, Shaykism and Alevism.
Similarly, Kharijites were initially divided into five major branches: Sufris, Azariqa, Najdat, Adjarites and Ibadis.
Among these numerous branches, only Hanafi, Maliki, Shafi'i, Hanbali, Imamiyyah-Ja'fari-Usuli, Nizārī Ismā'īlī, Alevi, Zaydi, Ibadi, Zahiri, Alawite, Druze and Taiyabi communities have survived. In addition, new schools of thought and movements like Quranist Muslims and Ahmadi Muslims later emerged independently.
Other religions.
There are sizeable non-Muslim minorities in many Muslim-majority countries, includes, Christians, Jews, Hindus, Buddhists, Baháʼís, Druzes, Yazidis, Mandaeans, Yarsanis and Zoroastrians.
The Muslim world is home to some of the world's most ancient Christian communities, and some of the most important cities of the Christian world—including three of its five great patriarchates (Alexandria, Antioch, and Constantinople). Scholars and intellectuals agree Christians have made significant contributions to Arab and Islamic civilization since the introduction of Islam, and they have had a significant impact contributing the culture of the Middle East and North Africa and other areas. Pew Research Center estimates indicate that in 2010, more than 64 million Christians lived in countries with Muslim majorities (excluding Nigeria). The Pew Forum study finds that Indonesia (21.1 million) has the largest Christian population in the Muslim world, followed by Egypt, Chad and Kazakhstan. While according to Adly A. Youssef and Martyn Thomas, in 2004, there were around 30 million Christians who lived in countries with Muslim majorities, with the largest Christian population number lived in Indonesia, followed by Egypt. Nigeria is divided almost evenly between Muslims and Christians, with more than 80 million Christians and Muslims.
In 2018, the Jewish Agency estimated that around 27,000 Jews live in Arab and Muslim countries. Jewish communities have existed across the Middle East and North Africa since the rise of Islam. Today, Jews residing in Muslim countries have been reduced to a small fraction of their former sizes, with the largest communities of Jews in Muslim countries exist in the non-Arab countries of Iran (9,500) and Turkey (14,500); both, however, are much smaller than they historically have been. Among Arab countries, the largest Jewish community now exists in Morocco with about 2,000 Jews and in Tunisia with about 1,000. The number of Druze worldwide is between 800,000 and one million, with the vast majority residing in the Levant (primarily in Syria and Lebanon).
In 2010, the Pew Forum study finds that Bangladesh (13.5 million), Indonesia (4 million), Pakistan (3.3 million) and Malaysia (1.7 million) has a sizeable Hindu minorities. Malaysia (5 million) has the largest Buddhist population in the Muslim world. Zoroastrians are the oldest remaining religious community in Iran.
Literacy and education.
The literacy rate in the Muslim world varies. Azerbaijan is in second place in the Index of Literacy of World Countries. Some members such as Iran, Kuwait, Kazakhstan, Tajikistan and Turkmenistan have over 97% literacy rates, whereas literacy rates are the lowest in Mali, Afghanistan, Chad and other parts of Africa. Several Muslim-majority countries, such as Turkey, Iran and Egypt have a high rate of citable scientific publications.
In 2015, the International Islamic News Agency reported that nearly 37% of the population of the Muslim world is unable to read or write, basing that figure on reports from the Organisation of Islamic Cooperation and the Islamic Educational, Scientific and Cultural Organization. In Egypt, the largest Muslim-majority Arab country, the youth female literacy rate exceeds that for males. Lower literacy rates are more prevalent in South Asian countries such as in Afghanistan and Pakistan, but are rapidly increasing. In the Eastern Middle East, Iran has a high level of youth literacy at 98%, but Iraq's youth literacy rate has sharply declined from 85% to 57% during the American-led war and subsequent occupation. Indonesia, the largest Muslim-majority country in the world, has a 99% youth literacy rate.
A 2011 Pew Research Center showed that at the time about 36% of all Muslims had no formal schooling, with only 8% having graduate and post-graduate degrees.
The highest of years of schooling among Muslim-majority countries found in Uzbekistan (11.5), Kuwait (11.0) and Kazakhstan (10.7). In addition, the average of years of schooling in countries in which Muslims are the majority is 6.0 years of schooling, which lag behind the global average (7.7 years of schooling). In the youngest age (25–34) group surveyed, Young Muslims have the lowest average levels of education of any major religious group, with an average of 6.7 years of schooling, which lag behind the global average (8.6 years of schooling). The study found that Muslims have a significant amount of gender inequality in educational attainment, since Muslim women have an average of 4.9 years of schooling, compared to an average of 6.4 years of schooling among Muslim men.

According to the UNHCR, Muslim-majority countries hosted 18 million refugees by the end of 2010.
Since then Muslim-majority countries have absorbed refugees from recent conflicts, including the uprising in Syria. In July 2013, the UN stated that the number of Syrian refugees had exceeded 1.8 million.
In Asia, an estimated 625,000 refugees from Rakhine, Myanmar, mostly Muslim, had crossed the border into Bangladesh since August 2017.
Culture.
Throughout history, Muslim cultures have been diverse ethnically, linguistically and regionally. According to M. M. Knight, this diversity includes diversity in beliefs, interpretations and practices and communities and interests. Knight says perception of Muslim world among non-Muslims is usually supported through introductory literature about Islam, mostly present a version as per scriptural view which would include some prescriptive literature and abstracts of history as per authors own point of views, to which even many Muslims might agree, but that necessarily would not reflect Islam as lived on the ground, 'in the experience of real human bodies'.
Classical culture.
The term "Islamic Golden Age" has been attributed to a period in history during which science, economic development and cultural works in most of the Muslim-dominated world flourished. The age is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786–809) with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world sought to translate and gather all the known world's knowledge into Arabic, and to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Siege of Baghdad in 1258. The Abbasids were influenced by the Quranic injunctions and hadiths, such as "the ink of a scholar is more holy than the blood of a martyr," that stressed the value of knowledge. The major Islamic capital cities of Baghdad, Cairo, and Córdoba became the main intellectual centers for science, philosophy, medicine, and education. During this period, the Muslim world was a collection of cultures; they drew together and advanced the knowledge gained from the ancient Greek, Roman, Persian, Chinese, Vedic, Egyptian, and Phoenician civilizations.
Ceramics.
Between the 8th and 18th centuries, the use of ceramic glaze was prevalent in Islamic art, usually assuming the form of elaborate pottery. Tin-opacified glazing was one of the earliest new technologies developed by the Islamic potters. The first Islamic opaque glazes can be found as blue-painted ware in Basra, dating to around the 8th century. Another contribution was the development of fritware, originating from 9th-century Iraq. Other centers for innovative ceramic pottery in the Old world included Fustat (from 975 to 1075), Damascus (from 1100 to around 1600) and Tabriz (from 1470 to 1550).
Literature.
The best known work of fiction from the Islamic world is "One Thousand and One Nights", a compilation of folk tales from Sanskrit, Persian, and later Arabian fables. The concept had been influenced by a pre-Islamic Persian prototype Hezār Afsān (Thousand Fables) that relied on particular Indian elements. It reached its final form by the 14th century; the number and type of tales have varied from one manuscript to another. This work has been very influential in the West since it was translated in the 18th century, first by Antoine Galland. Imitations were written, especially in France. Various characters from this epic have themselves become cultural icons in Western culture, such as Aladdin, Sinbad the Sailor and Ali Baba.
An example of Arabic poetry and Persian poetry on romance is "Layla and Majnun", dating back to the Umayyad era in the 7th century. It is a tragic story of undying love. Ferdowsi's "Shahnameh", the national epic of Greater Iran, is a mythical and heroic retelling of Persian history. "Amir Arsalan" was also a popular mythical Persian story.
Ibn Tufayl (Abubacer) and Ibn al-Nafis were pioneers of the philosophical novel. Ibn Tufail wrote the first Arabic novel "Hayy ibn Yaqdhan" ("Philosophus Autodidactus") as a response to Al-Ghazali's "The Incoherence of the Philosophers", and then Ibn al-Nafis also wrote a novel "Theologus Autodidactus" as a response to Ibn Tufail's "Philosophus Autodidactus". Both of these narratives had protagonists (Hayy in "Philosophus Autodidactus" and Kamil in "Theologus Autodidactus") who were autodidactic feral children living in seclusion on a desert island, both being the earliest examples of a desert island story. However, while Hayy lives alone with animals on the desert island for the rest of the story in "Philosophus Autodidactus", the story of Kamil extends beyond the desert island setting in "Theologus Autodidactus", developing into the earliest known coming of age plot and eventually becoming the first example of a science fiction novel.
"Theologus Autodidactus", written by the Arabian polymath Ibn al-Nafis (1213–1288), deals with various science fiction elements such as spontaneous generation, futurology, the end of the world and doomsday, resurrection, and the afterlife. Rather than giving supernatural or mythological explanations for these events, Ibn al-Nafis attempted to explain these plot elements using the scientific knowledge of biology, astronomy, cosmology and geology known in his time. Ibn al-Nafis' fiction explained Islamic religious teachings via science and Islamic philosophy. Translations of Ibn Tufail's "Philosophus Autodidactus" appeared in Latin (1671), English (1708), German, and Dutch. These European-language translations may have later inspired Daniel Defoe's "Robinson Crusoe" and Robert Boyle's "The Aspiring Naturalist".
Philosophy.
One of the common definitions for "Islamic philosophy" is "the style of philosophy produced within the framework of Islamic culture." Islamic philosophy, in this definition is neither necessarily concerned with religious issues, nor is exclusively produced by Muslims. The Persian scholar Ibn Sina (Avicenna) (980–1037) had more than 450 books attributed to him. His writings were concerned with various subjects, most notably philosophy and medicine. His medical textbook "The Canon of Medicine" was used as the standard text in European universities for centuries. He also wrote "The Book of Healing", an influential scientific and philosophical encyclopedia.
Another figure from the Islamic Golden Age, Avicenna, also founded his own Avicennism school of philosophy, which was influential in both Islamic and Christian lands.
Yet another influential philosopher who had an influence on modern philosophy was Ibn Tufail. His philosophical novel, "Hayy ibn Yaqdhan", translated into Latin as "Philosophus Autodidactus" in 1671, developed the themes of empiricism, tabula rasa, nature versus nurture, condition of possibility, materialism, and Molyneux's problem. European scholars and writers influenced by this novel include John Locke, Gottfried Leibniz, Melchisédech Thévenot, John Wallis, Christiaan Huygens, George Keith, Robert Barclay, the Quakers, and Samuel Hartlib.
Islamic philosophers continued making advances in philosophy through to the 17th century, when Mulla Sadra founded his school of Transcendent theosophy and developed the concept of existentialism.
Other influential Muslim philosophers include Ibn al-Haytham (Alhazen), a pioneer of phenomenology and the philosophy of science and a critic of Aristotelian natural philosophy and Aristotle's concept of place (topos); Al-Biruni, a critic of Aristotelian natural philosophy; Ibn Tufail and Ibn al-Nafis, pioneers of the philosophical novel; Shahab al-Din Suhrawardi, founder of Illuminationist philosophy; Fakhr al-Din al-Razi, a critic of Aristotelian logic and a pioneer of inductive logic; and Ibn Khaldun, a pioneer in the philosophy of history.
Sciences.
Ibn al-Haytham is also regarded as the father of optics, especially for his empirical proof of the intromission theory of light. Jim Al-Khalili stated in 2009 that Ibn al-Haytham is 'often referred to as the "world's first true scientist".' al-Khwarzimi's invented the log base systems that are being used today, he also contributed theorems in trigonometry as well as limits. Recent studies show that it is very likely that the Medieval Muslim artists were aware of advanced decagonal quasicrystal geometry (discovered half a millennium later in the 1970s and 1980s in the West) and used it in intricate decorative tilework in the architecture.
Muslim physicians contributed to the field of medicine, including the subjects of anatomy and physiology: such as in the 15th-century Persian work by Mansur ibn Muhammad ibn al-Faqih Ilyas entitled "Tashrih al-badan" ("Anatomy of the body") which contained comprehensive diagrams of the body's structural, nervous and circulatory systems; or in the work of the Egyptian physician Ibn al-Nafis, who proposed the theory of pulmonary circulation. Avicenna's "The Canon of Medicine" remained an authoritative medical textbook in Europe until the 18th century. Abu al-Qasim al-Zahrawi (also known as "Abulcasis") contributed to the discipline of medical surgery with his "Kitab al-Tasrif" ("Book of Concessions"), a medical encyclopedia which was later translated to Latin and used in European and Muslim medical schools for centuries. Other medical advancements came in the fields of pharmacology and pharmacy.
Some most famous scientists from the medieval Islamic world include Jābir ibn Hayyān, al-Farabi, Abu al-Qasim al-Zahrawi, Ibn al-Haytham, Al-Biruni, Avicenna, Nasir al-Din al-Tusi, and Ibn Khaldun.
Technology.
In technology, the Muslim world adopted papermaking from China. The knowledge of gunpowder was also transmitted from China via predominantly Islamic countries, where formulas for pure potassium nitrate were developed.
Advances were made in irrigation and farming, using new technology such as the windmill. Crops such as almonds and citrus fruit were brought to Europe through al-Andalus, and sugar cultivation was gradually adopted by the Europeans. Arab merchants dominated trade in the Indian Ocean until the arrival of the Portuguese in the 16th century. Hormuz was an important center for this trade. There was also a dense network of trade routes in the Mediterranean, along which Muslim-majority countries traded with each other and with European powers such as Venice, Genoa and Catalonia (see also: Indo-Mediterranean). The Silk Road crossing Central Asia passed through Islamic states between China and Europe. The emergence of major economic empires with technological resources after the conquests of Timur (Tamerlane) and the resurgence of the Timurid Renaissance include the Mali Empire and the Bengal Sultanate in particular, a major global trading nation in the world, described by the Europeans to be the "richest country to trade with".
Muslim engineers in the Islamic world made a number of innovative industrial uses of hydropower, and early industrial uses of tidal power and wind power. The industrial uses of watermills in the Islamic world date back to the 7th century, while horizontal-wheeled and vertical-wheeled water mills were both in widespread use since at least the 9th century. A variety of industrial mills were being employed in the Islamic world, including early fulling mills, gristmills, paper mills, hullers, sawmills, ship mills, stamp mills, steel mills, sugar mills, tide mills and windmills. By the 11th century, every province throughout the Islamic world had these industrial mills in operation, from al-Andalus and North Africa to the Middle East and Central Asia. Muslim engineers also invented crankshafts and water turbines, employed gears in mills and water-raising machines, and pioneered the use of dams as a source of water power, used to provide additional power to watermills and water-raising machines. Such advances made it possible for industrial tasks that were previously driven by manual labour in ancient times to be mechanized and driven by machinery instead in the medieval Islamic world. The transfer of these technologies to medieval Europe had an influence on the Industrial Revolution, particularly from the proto-industrialised Mughal Bengal and Tipu Sultan's Kingdom, through the conquests of the East India Company.
Arts.
The term "Islamic art and architecture" denotes the works of art and architecture produced from the 7th century onwards by people who lived within the territory that was inhabited by culturally Islamic populations.
Aniconism.
No Islamic visual images or depictions of God are meant to exist because it is believed that such artistic depictions may lead to idolatry. Muslims describe God by the names and attributes that, according to Islam, he revealed to his creation. All but one sura of the Quran begins with the phrase "In the name of God, the Beneficent, the Merciful". Images of Mohammed are likewise prohibited. Such aniconism and iconoclasm can also be found in Jewish and some Christian theology.
Arabesque.
Islamic art frequently adopts the use of geometrical floral or vegetal designs in a repetition known as arabesque. Such designs are highly nonrepresentational, as Islam forbids representational depictions as found in pre-Islamic pagan religions. Despite this, there is a presence of depictional art in some Muslim societies, notably the miniature style made famous in Persia and under the Ottoman Empire which featured paintings of people and animals, and also depictions of Quranic stories and Islamic traditional narratives. Another reason why Islamic art is usually abstract is to symbolize the transcendence, indivisible and infinite nature of God, an objective achieved by arabesque. Islamic calligraphy is an omnipresent decoration in Islamic art, and is usually expressed in the form of Quranic verses. Two of the main scripts involved are the symbolic "kufic" and "naskh" scripts, which can be found adorning the walls and domes of mosques, the sides of minbars, and so on.
Distinguishing motifs of Islamic architecture have always been ordered repetition, radiating structures, and rhythmic, metric patterns. In this respect, fractal geometry has been a key utility, especially for mosques and palaces. Other features employed as motifs include columns, piers and arches, organized and interwoven with alternating sequences of niches and colonnettes. The role of domes in Islamic architecture has been considerable. Its usage spans centuries, first appearing in 691 with the construction of the Dome of the Rock mosque, and recurring even up until the 17th century with the Taj Mahal. And as late as the 19th century, Islamic domes had been incorporated into European architecture.
Calendar.
Two calendars are used all over the Muslim world. One is a lunar calendar that is most widely used among Muslims. The other one is a solar calendar officially used in Iran and Afghanistan.
Women.
According to "Riada Asimovic Akyol," while Muslim women's experiences differ a lot by location and personal situations such as family upbringing, class and education; the difference between culture and religions is often ignored by community and state leaders in many of the Muslim majority countries. The key issue in the Muslim world regarding gender issues is that religious texts constructed in highly patriarchal environments and based on biological essentialism are still valued highly in Islam, hence views emphasizing on men's superiority in unequal gender roles are widespread among many conservative Muslims (men and women). Orthodox Muslims often believe that rights and responsibilities of women in Islam are different from that of men and sacrosanct since assigned by the God. According to Asma Barlas, patriarchal behaviour among Muslims is based in an ideology which jumbles sexual and biological differences with gender dualisms and inequality. Modernist discourse of liberal progressive movements like Islamic feminism have been revisiting hermeneutics of feminism in Islam in terms of respect for Muslim women's lives and rights. "Riada Asimovic Akyol" further says that equality for Muslim women needs to be achieved through self-criticism.
