Ibn Sina (Avicenna)

Early lifeHe was born in around 370 (AH) / 980 (AD) in Afshana, his mother's home, a small city now part of Uzbekistan

His father, a respected Ismaili scholar, was from Balkh now part of Afghanistan .He had his son very carefully educated at Bukhara.

Ibn Sina's independent thought was served by an extraordi-nary intelligence and memory, which allowed him to overtake his teachers at the age of fourteen.

Early lifeAccording to his autobiography, ibn sina had memorised the entire Quran by at the age of 10 and Persian poetry as well.

He learned  Indian arithmetic from Mahmoud Massahi

He also studied Fiqh (Islamic jurisprudence).Ibn Sina's when a teenager, he was greatly troubled by the Metaphysics of Aristotle, which he could not understand until he read al-Farabi's .

He also studied philosophy.

Father of Modern MedicineHe turned to medicine at 16.

He achieved full status as a qualified physician at age 18 and found that "Medicine is no hard and thorny science, like  mathematics and metaphysics so I soon made great progress; I became an excellent doctor and began to treat patients, using approved remedies.“

The youthful physician's fame spread quickly, and he treated many patients without asking for payment

RewardIbn Sina's first appointment was that of physician to the emir.

In reward for this service was access to the royal library of the Samanids, well-known patrons of scholarship and schol-ars.

When the library was destroyed by fire not long after, the enemies of Ibn Sina accused him of burning it

When Ibn Sina was 22 years old, he lost his father.

  Ibn Sina seems to have declined the offers of Mahmud of Ghazni, and proceeded in modern Turkmenistan.

 Ibn Sina wandered from place to place through the districts of Nishapur and Merv to the borders of Khorasan.

 Ibn Sina settled at Rey (Tehran).

Ibn Sina's composed about thirty books in Rey

Later life and deathThe remaining ten or twelve years of Ibn Sīnā's life were spent in the service of  ruler Muhammad ibn Rustam Dush-manziyarHis friends advised him to slow down and take life moder-ately. He refused, however, stating that: "I prefer a short life with width to a narrow one with length". He bestowed his goods on the poor, restored unjust gains, freed his slaves.

He read through the Quran every three days until his death. He died in June 1037, in his fifty-eighth year, in the month of  Ramadan and was buried in Hamadan Iran

some were written in the Persian language.

Psychophysiology and Psychosomatic medicine

Recognized 'physiological psychology' in the treatment of ill-nesses involving emotions, and developed a system for associ-ating changes in the pulse rate with inner feelings.Avicenna is reported to have treated a very ill patient by "feel-ing the patient's pulse and reciting aloud to him the names of provinces, districts, towns, streets, and people." He noticed how the patient's pulse increased when certain names were mentioned, from which Avicenna deduced that the patient was in love with a girl whose home Avicenna was "able to locate by the digital examination." Avicenna advised the patient to marry the girl he is in love with, and the patient soon recov-ered from his illness after his marriage.

Physics

In mechanics The Book of Healing, developed a theory of motion.

In which he made a distinction between the inclination and force of a projectile, and concluded that motion was a re-sult of an inclination transferred to the projectile by the thrower, and that projectile motionin a vacuum would not cease

Astronomy and astrology

He believed that each planet had some influence on the earth, but argued against astrologers being able to determine the exact effects

Avicenna wrote an attack on astrology titled Resāla fī ebṭāl aḥkām al-nojūm

TheologyHis aim was to prove the existence of God and His creation of the world scientifically and through reason and logic. Avicenna's views on 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 Is-lamic theology. These included treatises on the prophets (whom he viewed as "inspired philosophers"), and also on various scientific and philosophical interpretations of the Quran. In general these treatises linked his philosophical writings to Islamic religious ideas; for example, the body after life

Poetry

, زحل اوج تا سياه گل قع�ر ازUp from Earth's Centre through the Seventh Gate, حل را گيتی مشکالت همه کردمI rose, and on the Throne of Saturn sate,, حيل و مکر هر زقيد جستم بيرونAnd many Knots unravel'd by the Road;. اجل بند مگر شد گشاده بند هرBut not the Master-Knot of Human Fate.

QuotesThe world is divided into men who have wit and no religion and men who have religion and no wit.

As to the mental essence, we find it in infants devoid of ev-ery mental form.

That whose existence is necessary must necessarily be one essence.

Therefore in medicine we ought to know the causes of sick-ness and health.
