Ibn Sīnā studied medicine under a physician named Koushyar. He wrote almost 450 treatises on a wide range of subjects, of which around 240 have survived. In particular, 150 of his surviving treatises concentrate on philosophy and 40 of them concentrate on medicine. His most famous works are The Book of Healing, a vast philosophical and scientific encyclopaedia, and The Canon of Medicine, which was a standard medical text at many medieval universities. The Canon of Medicine was used as a text-book in the universities of Montpellier and Louvain as late as 1650.
Ibn Sīnā's Canon of Medicine provides a complete system of medicine according to the principles of Galen (and Hippocrates).
George Sarton, an early author of the history of science, wrote in the Introduction to the History of Science:
One of the most famous exponents of Muslim universalism and an eminent figure in Islamic learning was Ibn Sina, known in the West as Avicenna (981-1037). For a thousand years he has retained his original renown as one of the greatest thinkers and medical scholars in history. His most important medical works are the Qanun (Canon) and a treatise on Cardiac drugs. The 'Qanun fi-l-Tibb' is an immense encyclopedia of medicine. It contains some of the most illuminating thoughts pertaining to distinction of mediastinitis from pleurisy; contagious nature of phthisis; distribution of diseases by water and soil; careful description of skin troubles; of sexual diseases and perversions; of nervous ailments.
Circumstances
Avicenna created an extensive corpus of works during what is commonly known as Islam's Golden Age, in which the translations of Graeco-Roman, Persian and Indian texts were studied extensively. Graeco-Roman (Mid- and Neo-Platonic, and Aristotelian) texts by the Kindi school were commented, redacted and developed substantially by Islamic intellectuals, who also built upon Persian and Indian mathematical systems, astronomy, algebra, trigonometry and medicine. The Samanid dynasty in Greater Khorasan and central Asia as well as Buwayhid in the western part of Persia and Iraq could provide a thriving atmosphere for scholarly and cultural development. Under the Samanids, Bukhara rivalled Baghdad as a cultural capital of Islam.
The study of Quran and Hadith thrived in such a scholarly atmosphere. Philosophy, Fiqh and theology (kalam) were further developed, most noticeably by Avicenna and his opponents. Al-Razi and Al-Farabi had provided methodology and knowledge in medicine and philosophy. Avicenna could use the great libraries of Balkh, Khwarezm, Gorgan, Rey, Isfahan and Hamedan. As various texts, such as the 'Ahd with Bahmanyar show, he debated philosophical points with the greatest scholars of the time. As Aruzi Samarqandi describes in his four articles before Avicenna left Khwarezm he had met Abu Rayhan Biruni (a famous scientist and astronomer), Abu Nasr Iraqi (a renowned mathematician), Abu Sahl Masihi (a respected philosopher) and Abu al-Khayr Khammar (a great physician).
Biography
Early life
His full name was Hussain ibn Abdullah ibn Hassan ibn Ali ibn Sina. He was born around 980 in Afshana, near Bukhara, which was his mother's hometown, in Greater Khorasan. His father, Abdullah, was a respected Ismaili scholar from Balkh, an important town of the Samanid Emirate, in what is today Balkh Province, Afghanistan. Prominent theologian Henry Corbin believed that Ibn Sina himself was a good ismaili. His mother was named Setarah. His father was at the time of his son's birth the governor in one of the Samanid Nuh ibn Mansur's estates. He had his son very carefully educated at Bukhara. Ibn Sina's independent thought was served by an extraordinary intelligence and memory, which allowed him to overtake his teachers at the age of fourteen. As he said in his autobiography, there was nothing that he had not learned when he reached eighteen.
Ibn Sīnā was put under the charge of a tutor, and his precocity soon made him the marvel of his neighbours; he displayed exceptional intellectual behaviour and was a child prodigy who had memorized the Qur'an by the age of 10 and a great deal of Persian poetry as well. He learned Indian arithmetic from an Indian greengrocer, and he began to learn more from a wandering scholar who gained a livelihood by curing the sick and teaching the young. He also studied Fiqh (Islamic jurisprudence) under the Hanafi scholar Ismail al-Zahid.
As a teenager, he was greatly troubled by the Metaphysics of Aristotle, which he could not understand until he read al-Farabi's commentary on the work. For the next year and a half, he studied philosophy, in which he encountered greater obstacles. In such moments of baffled inquiry, he would leave his books, perform the requisite ablutions (wudu), then go to the mosque, and continue in prayer (salah) till light broke on his difficulties. Deep into the night he would continue his studies, and even in his dreams problems would pursue him and work out their solution. Forty times, it is said, he read through the Metaphysics of Aristotle, till the words were imprinted on his memory; but their meaning was hopelessly obscure, until one day they found illumination, from the little commentary by Farabi, which he bought at a bookstall for the small sum of three dirhams. So great was his joy at the discovery, thus made by help of a work from which he had expected only mystery, that he hastened to return thanks to God, and bestowed alms upon the poor.
He turned to medicine at 16, and not only learned medical theory, but also by gratuitous attendance of the sick had, according to his own account, discovered new methods of treatment. The teenager 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.
Adulthood
His first appointment was that of physician to the emir, who owed him his recovery from a dangerous illness (997). Ibn Sina's chief reward for this service was access to the royal library of the Samanids, well-known patrons of scholarship and scholars. When the library was destroyed by fire not long after, the enemies of Ibn Sina accused him of burning it, in order for ever to conceal the sources of his knowledge. Meanwhile, he assisted his father in his financial labours, but still found time to write some of his earliest works.
When Ibn Sina was 22 years old, he lost his father. The Samanid dynasty came to its end in December 1004. Ibn Sina seems to have declined the offers of Mahmud of Ghazni, and proceeded westwards to Urgench in the modern Uzbekistan, 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 Dailam and central Persia, himself a poet and a scholar, with whom Ibn Sina had expected to find an asylum, was about that date (1012) starved to death by his troops who had revolted. Ibn Sina himself was at this season stricken down by a severe illness. Finally, at Gorgan, near the Caspian Sea, Ibn Sina met with a friend, who bought a dwelling near his own house in which Ibn Sina lectured on logic and astronomy. Several of Ibn Sina's treatises were written for this patron; and the commencement of his Canon of Medicine also dates from his stay in Hyrcania.
Ibn Sina subsequently settled at Rai, in the vicinity of modern Tehran, (present day capital of Iran), the home town of Rhazes; where Majd Addaula, a son of the last Buwayhid emir, was nominal ruler under the regency of his mother (Seyyedeh Khatun). About thirty of Ibn Sina's shorter works are said to have been composed in Rai. Constant feuds which raged between the regent and her second son, Shams al-Daula, however, compelled the scholar to quit the place. After a brief sojourn at Qazvin he passed southwards to Hamadãn where Shams al-Daula, another Buwayhid emir, had established himself. At first, Ibn Sina entered into the service of a high-born lady; but the emir, hearing of his arrival, called him in as medical attendant, and sent him back with presents to his dwelling. Ibn Sina was even raised to the office of vizier. The emir consented that he should be banished from the country. Ibn Sina, however, remained hidden for forty days in a sheikh Ahmed Fadhel's house, until a fresh attack of illness induced the emir to restore him to his post. Even during this perturbed time, Ibn Sina persevered with his studies and teaching. Every evening, extracts from his great works, the Canon and the Sanatio, were dictated and explained to his pupils. On the death of the emir, Ibn Sina ceased to be vizier and hid himself in the house of an apothecary, where, with intense assiduity, he continued the composition of his works.
Meanwhile, he had written to Abu Ya'far, the prefect of the dynamic city of Isfahan, offering his services. The new emir of Hamadan, hearing of this correspondence and discovering where Ibn Sina was hidden, incarcerated him in a fortress. War meanwhile continued between the rulers of Isfahan and Hamadãn; in 1024 the former captured Hamadan and its towns, expelling the Tajik mercenaries. When the storm had passed, Ibn Sina returned with the emir to Hamadan, and carried on his literary labors. Later, however, accompanied by his brother, a favorite pupil, and two slaves, Ibn Sina escaped out of the city in the dress of a Sufi ascetic. After a perilous journey, they reached Isfahan, receiving an honorable welcome from the prince.
Later life and death
The remaining ten or twelve years of Ibn Sīnā's life were spent in the service of Abu Ja'far 'Ala Addaula, whom he accompanied as physician and general literary and scientific adviser, even in his numerous campaigns.
During these years he began to study literary matters and philology, instigated, it is asserted, by criticisms on his style. A severe colic, which seized him on the march of the army against Hamadan, was checked by remedies so violent that Ibn Sina could scarcely stand. On a similar occasion the disease returned; with difficulty he reached Hamadan, where, finding the disease gaining ground, he refused to keep up the regimen imposed, and resigned himself to his fate.
His friends advised him to slow down and take life moderately. He refused, however, stating that: "I prefer a short life with width to a narrow one with length". On his deathbed remorse seized him; he bestowed his goods on the poor, restored unjust gains, freed his slaves, and read through the Qur'an 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 Hamedan, Iran.
The Canon of Medicine
About 100 treatises were ascribed to Ibn Sina. Some of them are tracts of a few pages, others are works extending through several volumes. The best-known amongst them, and that to which Ibn Sina owed his European reputation, is his 14-volume The Canon of Medicine, which was a standard medical text in Europe and the Islamic world up until the 18th century.
Medicine and pharmacology
The book is known for the discovery of contagious diseases and sexually transmitted diseases, the introduction of quarantine to limit the spread of infectious diseases, the introduction of experimental medicine, clinical trials, neuropsychiatry, risk factor analysis, and the idea of a syndrome in the diagnosis of specific diseases, and hypothesized the existence of microrganisms. Ibn Sīnā adopted, from the Greeks, the theory that epidemics are caused by pollution in the air (miasma). It classifies and describes diseases, and outlines their assumed causes. Hygiene, simple and complex medicines, and functions of parts of the body are also covered. In this, Ibn Sīnā is credited as being the first to correctly document the anatomy of the human eye, along with descriptions of eye afflictions such as cataracts. It asserts that tuberculosis was contagious, which was later disputed by Europeans, but turned out to be true. It also describes the symptoms and complications of diabetes. Both forms of facial paralysis were described in-depth. In addition, the workings of the heart as a valve are described.[citation needed]
The Canon of Medicine was the first book dealing with experimental medicine, evidence-based medicine, randomized controlled trials, and efficacy tests, and it laid out the following rules and principles for testing the effectiveness of new drugs and medications, which still form the basis of clinical pharmacology and modern clinical trials:
- The drug must be free from any extraneous accidental quality.
- It must be used on a simple, not a composite, disease.
- The drug must be tested with two contrary types of diseases, because sometimes a drug cures one disease by Its essential qualities and another by its accidental ones.
- The quality of the drug must correspond to the strength of the disease. For example, there are some drugs whose heat is less than the coldness of certain diseases, so that they would have no effect on them.
- The time of action must be observed, so that essence and accident are not confused.
- The effect of the drug must be seen to occur constantly or in many cases, for if this did not happen, it was an accidental effect.
- The experimentation must be done with the human body, for testing a drug on a lion or a horse might not prove anything about its effect on man.
An Arabic edition of the Canon appeared at Rome in 1593, and a Hebrew version at Naples in 1491. Of the Latin version there were about thirty editions, founded on the original translation by Gerard de Sabloneta. In the 15th century a commentary on the text of the Canon was composed. Other medical works translated into Latin are the Medicamenta Cordialia, Canticum de Medicina, and the Tractatus de Syrupo Acetoso.
It was mainly accident which determined that from the 12th to the 18th century, Ibn Sīnā should be the guide of medical study in European universities, and eclipse the names of Rhazes, Ali ibn al-Abbas and Averroes. His work is not essentially different from that of his predecessor Rhazes, because he presented the doctrine of Galen, and through Galen the doctrine of Hippocrates, modified by the system of Aristotle, as well as the Indian doctrines of Sushruta and Charaka. But the Canon of Ibn Sīnā is distinguished from the Al-Hawi (Continens) or Summary of Rhazes by its greater method, due perhaps to the logical studies of the former.
The work has been variously appreciated in subsequent ages, some regarding it as a treasury of wisdom, and others, like Averroes, holding it useful only as waste paper. In modern times it has been mainly of historic interest as most of its tenets have been disproved or expanded upon by scientific medicine. The vice of the book is excessive classification of bodily faculties, and over-subtlety in the discrimination of diseases. It includes five books; of which the first and second discuss physiology, pathology and hygiene, the third and fourth deal with the methods of treating disease, and the fifth describes the composition and preparation of remedies. This last part contains some personal observations.
He is ample in the enumeration of symptoms, and is said to be inferior in practical medicine and surgery. He introduced into medical theory the four causes of the Peripatetic system. Of natural history and botany he pretended to no special knowledge. Up to the year 1650, or thereabouts, the Canon was still used as a textbook in the universities of Leuven and Montpellier.
In the museum at Bukhara, there are displays showing many of his writings, surgical instruments from the period and paintings of patients undergoing treatment. Ibn Sīnā was interested in the effect of the mind on the body, and wrote a great deal on psychology, likely influencing Ibn Tufayl and Ibn Bajjah. He also introduced medical herbs.
Avicenna extended the theory of temperaments in The Canon of Medicine to encompass "emotional aspects, mental capacity, moral attitudes, self-awareness, movements and dreams." He summarized his version of the four humours and temperaments in a table as follows:
| Evidence | Hot | Cold | Moist | Dry |
|---|---|---|---|---|
| Morbid states | inflammations become febrile | fevers related to serious humour, rheumatism | lassitude | loss of vigour |
| Functional power | deficient energy | deficient digestive power | difficult digestion | |
| Subjective sensations | bitter taste, excessive thirst, burning at cardia | Lack of desire for fluids | mucoid salivation, sleepiness | insomnia, wakefulness |
| Physical signs | high pulse rate, lassitude | flaccid joints | diarrhea, swollen eyelids, rough skin, acquired habit | rough skin, acquired habit |
| Foods & medicines | calefacients harmful, infrigidants beneficial | infrigidants harmful, calefacients beneficial | moist articles harmful | dry regimen harmful, humectants beneficial |
| Relation to weather | worse in summer | worse in winter | bad in autumn |
Physical Exercise: the Key to Health
The Canon of Medicine: Volume 1 of 5; Part 4 of 5: The Preservation of Health
Ibn Sina's Canon of Medicine which is written in 5 volumes, only the first volume has appeared in the English Language. In the first volume, Ibn Sina divides medicine into two parts as he explains it throughout the first book: the theoretical and the practical. The theoretical part consists of; but is not excluded to such things as: the causes of health and disease, the temperaments, the humours, the anatomy, general physiology, the breath, psychology, discussion of causes diseases and symptoms, the causes of illness, the classification of diseases, the pulse, the urine etc.
As he himself says in the book on pg 353 "In the first part of this book it was stated that medicine comprises two parts, one theoretical, and one practical, though both are really speculative science." (Avicenna 1999, p. 353)
Theoretical and Practical Medicine
Ibn Sina goes on to say that you do not get any benefit from just knowing how your body works, but rather the true benefit of medicine itself is in its practical aspect, since medicine is for the preservation of health.
"That which is speculative named theory relates to the formation of opinions and the showing of the evidence upon which they are based, without reference to the mode of acting upon them. Thus this part deals with the temperaments, the humors, the drives, and with the forms, the symptoms, and the causes of disease. That which is specially named practical relates to the mode of acting upon this knowledge, and the prescription of a regimen." (Avicenna 1999, p. 353)
The Benefits of Exercise
Once the purpose of medicine has been set forth, then from pages 377-455, Ibn Sina divides the way of achieving health as:
"Since the regimen of maintaining health consists essentially in the regulation of: (1) exercise (2) food and (3) sleep, we may begin our discourse with the subject of exercise". (Avicenna 1999, p. 377)
Exercise itself is divided into three main parts: The Massage (which is equivalent to massaging your muscles before you start to exercise); The Exercise itself; and lastly the Cold Bath.
Giving one of the greatest benefits of the regimen of exercise, and then explaining the extremely important and necessary need for physical exercise; Ibn Sina states:
"Once we direct the attention towards regulating exercise as to amount and time, we shall find there is no need for such medicines as are ordinarily required for remedying diseases dependent on [abnormal] matters, or diseases of temperament consequent upon such. This is true provided the rest of the regimen is appropriate and proper." (Avicenna 1999, p. 377)
The value of exercise includes the following (1) it hardens the organs and renders them fit for their functions (2) it results in a better absorption of food, aids assimilation, and, by increasing the innate heat, improves nutrition (3) it clears the pores of the skin (4) it removes effete substances through the lungs (5) it strengthens the physique. Vigorous exercise invigorates the muscular and nervous system." (Avicenna 1999, p. 379)
In what manner does Ibn Sina uses the word temperament? In saying that exercise cures diseases of temperamant
We shall not mention everything Ibn Sina has said on this topic, but of extreme importance is the division Ibn Sina shows of a person whose temperament is harmonious and the other whose temperament is non-uniform. Ibn Sina says on pg 276-277
"In addition to the signs of the normal temperament already given, there are: Mental faculties include: vigor of imagination, intellectual power, and memory." (Avicenna 1999, p. 276)
"In brief, there is non-uniformity of temperament among the members; or, perchance, the principal members depart from equability and come to be of contrary temperament, one deviating towards one, amother to its contrary. If the components of the body are out of proportion, it is unfortunate both for talent and reasoning power." (Avicenna 1999, p. 277)
The Purpose of Exercise and the Dangers of its negligence
Continuing on the proof to why exercise should be so beneficial Ibn Sina says "We know that this must be so when we reflect how in regard to nutriment, our health depends on the nutriment being appropriate for us and regulated in quantity and quality. For not one of the aliments which are capable of nourishing the body is converted into actual nutriment in its entirety. In every case digestion leaves something untouched, and nature takes care to have that evacuated. Nevertheless, the evacuation which nature accomplishes is not a complete one. Hence at the end of each digestion there is some superfluity left over. Should this be a frequent occurrence, repetition would lead to further aggregation until something measurable has accumulated. As a result, harmful effete substances would form and injure various parts of the body. When they undergo decomposition, putrefactive diseases arise [bacterial infections]. Should they be strong in quality, they will give rise to intemperament; and if they should increase in quantity, they would set up the symptoms of plethora which have already been described. Flowing to some member, they will result in an inflammatory mass, and their vapors will destroy the temperament of the substantial basis of the breath.That is the reason why we must be careful to evacuate these substances. Their evacuation is usually not completely accomplished without the aid of toxic medicines, for these break up the nature of the effate substances. This can be achieved only by toxic agents, although the drinking of them is to a certain extent deleterious to our nature. As Hippocrates says: "Medicine purges and ages." More than this the discharge of superfluous humor entails the loss of a large part of the natural humidities and of the breath, which is the substance of life. All this is at the expense of the strength of the principal and the auxiliary members, and therefore they are weakened thereby. These and other things account for the difficulties incident to plethora, whether they remain behind in the body or are evacuated by it." (Avicenna 1999, pp. 377–8)
Just before this Ibn Sina explained how accumulation of food in our body, can cause diseases, and one way to rid us of this is strong medicines. However, as he explains; this is not the ideal way, and certainly not the long-term. Thus, to make his point very clear, and show the extreme necessity of daily exercise for health, Ibn Sina states:
"Now exercise is that agent which most surely prevents the accumulation of these matters, and prevents plethora. The other forms of regiment assist it. It is this exercise which renews and revives the innate heat, and imparts the necessary lightness to the body, for it causes the subtle heat to be increased and daily disperses whatever effete substances have accumulated; the movements of the body help them to expel them conveying them to those parts of the body whence they can readily leave it. Hence the effete matters are not allowed to collect day after day and besides this, as we have just said, exercise causes the innate heat to flourish and keeps the joints and ligaments firm, so as to be always ready for service, and also free from injury. It renders the members able to receive nutriment, in being free from accumulated effate matters. Hence it renders the members light and the humidities attenuated, and it dilates the pores of the skin.To forsake exercise would often incur the risk of "hectic", because the instinctive drives of the members are impaired, inasmuch as the deprivation of movement prevents the access to them of the innate breath. And this last is the real instrument of life for every one of the members." (Avicenna 1999, pp. 378–9)
Massage
Before you begin to exercise it is important that you massage your muscles; as Ibn Sina says on page 385:
"Massage as a preparatory to athletics. The massage begins gently, and then becomes more vigorous as the time approaches for the exercise." (Avicenna 1999, p. 385)
Exercises
The exercises themselves are divided into 'strenuous, mild, vigorous and brisk'. On pages 379-381; Ibn Sina states the types of exercises under each type:
"Strenuous exercises include: wrestling contests, boxing, quick marching, running, jumping over an object higher than one foot, throwing the javelin, fencing, horsemanship, swimming. Mild exercises include: fishing, sailing, being carried on camels, swinging to and fro. Vigorous exercises include: those performed by soldiers in camp, in military sports; field running, long jumping, high jumping, polo, stone throwing, lifting heavy stones or weights, various forms of wrestling. Brisk exercises include: involves interchanging places with a partner as swiftly as possible, each jumping to and fro, either in time [to music] or irregularly." (Avicenna 1999, pp. 379–81)
There are certain important things to note once you start exercising, one is the amount, the other consistency; Ibn Sina states about the amount:
"(1) the color - as long as the skin goes on becoming florid, the exercise may be continued. After it ceases to do so, the exercise must be discontinued." (Avicenna 1999, p. 384)
On being consistent with exercise Ibn Sina states (on the importance of having a regimen):
"At the conclusion of the first day's exercise, you will know the degree of exercise allowable and when you know the amount of nourishment the person can bear, do not make any change in either on the second day. Arrange that the measure of aliment, and the amount of exercise shall not exceed that limit ascertained on the first day." (Avicenna 1999, p. 385)
On the side note those who think themselves to be elderly, and thus think of shunning exercise, Ibn Sina write a complete chapter titled "Concerning the Elderly" in the Qanun, and states the same regimen for them, as he does for others. He states on page 433
"For if, towards the end of life, the body is still equable, it will be right to allow attempered exercises. If one part of the body should not be in a first-rate condition, then that part should not be exercised until the others have been exercised..... On the other hand, if the ailment were in the feet, the the exercise should employ the upper limbs: for instance, rowing, throwing weights, lifting weights." (Avicenna 1999, p. 433)
Bathing in Cold Water
Once you have finished exercising; it is often that the person will feel tired and fatigued; to combat this problem Ibn Sina says on page 388:
"The beneficial Effects of Baths: The benefits are (1) induction of sleep (2) dilation of pores (3) cleansing of skin (4) dispersal of the undesirable waste matters (5) maturation of abscesses (6) drawing of nutriment towards the surface of the body (7) assistance to the physiological dispersion and excretion of poisonous matters (8) prevention of diarrhea and (9) removal of fatigue effects." (Avicenna 1999, p. 388)
Most importantly you should remember:
"A person should not go into the bath immediately after exercise. He should rest properly first." (Avicenna 1999, p. 387)
There are two more things that are important to mention on this subject:
"Injurious effects include the fact that the heart is weakened if the person stays too long in the bath" (Avicenna 1999, p. 388)
"Cold Bathing should not be done after exercise except in the case of the very robust. Even then the rules which we have given should be followed. To use cold baths in the ways we have named drives the natural heat suddenly into the interior parts, and then invigorates the strength so that the person should leave the bath twice as strong as when he entered." (Avicenna 1999, p. 390)
Diet
Once Ibn Sina has laid the foundation of exercise being central to health, he names many exercises as running, swimming, weight lifting, polo, fencing, boxing, wrestling, long jumping, high jumping, etc. on page 380. To relate everything written in this book would take too much space, so after choosing a vigorous exercise regimen for yourself daily, which you can do daily, consistently as Ibn Sina states, he also gives a Diet to go along with this. Ibn Sina states:
"The meal should include: (1) meat especially kid of goats; veal, and year-old lambs [this means white meat in today`s terms] (2) wheat, which is cleaned of extraneous matter and gathered during a healthy harvest without ever being exposed to injurious influences (3) sweets (fruits) of appropriate temperament." (Avicenna 1999, p. 390)
After setting out the meal plan for health, Ibn Sina talks about how many times we should be eating a day by stating on page 396:
"In taking successive satiating meals, it is best for a person to take only one on one day and two on the next(morning and evening). But one must not be too strict in this rule, for if a person is accustomed to have two meals a day, and then takes only one, he will be weakened and his digestive faculty will suffer. A person of weak digestion should take two meals a day lessening the amount partaken. On occasion he may eat once a day. A person who is accustomed to eat once a day, on resuming the habit of two meals a day, suffer from weakness, lack of energy, slackness. If he should take no food at bedtime, he will feel weak; and if he should take a late meal he will not be able to digest it, and will have acid eructations, nausea, bitter taste in the mouth, loose bowels and become moody, or irritable. This is because he has put into his stomach something to which it is not accustomed, and so he is liable to show some of the symptoms which befall a person whose aliment is not fully digested and these you are now acquainted with." (Avicenna 1999, pp. 396–97)
Lastly, the third thing mentioned is sleep; to make sure that you do not sleep during the days, and do not stay awake during the nights. From the above reading, it is clear that Ibn Sina gave advice in his book which is still the same advice medical doctors give to their patients. Daily Physical Exercise; and to defeat diseases such as type 2 diabetes, high blood pressure, the prescription of a diet which contains high amounts of Whole Grains and little to no amounts of Refined Carbohydrates.
Psychology
In Muslim psychology and the neurosciences, Avicenna was a pioneer of neuropsychiatry. He first described numerous neuropsychiatric conditions, including hallucination, insomnia, mania, nightmare, melancholia, dementia, epilepsy, paralysis, stroke, vertigo and tremor.
Avicenna was also a pioneer in psychophysiology and psychosomatic medicine. He recognized 'physiological psychology' in the treatment of illnesses involving emotions, and developed a system for associating changes in the pulse rate with inner feelings, which is seen as an anticipation of the word association test attributed to Carl Jung. Avicenna is reported to have treated a very ill patient by "feeling 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 recovered from his illness after his marriage.
In The Canon of Medicine, Avicenna dealt with neuropsychiatry and described a number of neuropsychiatric conditions, including melancholia. He described melancholia as a depressive type of mood disorder in which the person may become suspicious and develop certain types of phobias.
Unani medicine
Though the threads which comprise Unani healing can be traced all the way back to Claudius Galenus of Pergamum, who lived in the 2nd century of the Christian Era, the basic knowledge of Unani medicine as a healing system was developed by Hakim Ibn Sina in his medical encyclopedia The Canon of Medicine. The time of origin is thus dated at circa 1025 AD, when Avicenna wrote The Canon of Medicine in Persia. While he was primarily influenced by Greek and Islamic medicine, he was also influenced by the Indian medical teachings of Sushruta and Charaka.. Hakim Syed Zillur Rahman, a scholar of Unani medicine works on Ibn Sina. Following of his works on Ibn Sina are of significance:

The Book of Healing
Earth sciences
Ibn Sīnā wrote on Earth sciences such as geology in The Book of Healing, in which he developed the concept of uniformitarianism and law of superposition in geology. While discussing the formation of mountains, he explained:
Either they are the effects of upheavals of the crust of the earth, such as might occur during a violent earthquake, or they are the effect of water, which, cutting itself a new route, has denuded the valleys, the strata being of different kinds, some soft, some hard... It would require a long period of time for all such changes to be accomplished, during which the mountains themselves might be somewhat diminished in size.
Due to his fundamental contributions to the development of geology, particularly regarding the origins of mountains, Avicenna has been called the 'Father of Geology'.
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 discusses 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 explains that the ideal situation is when one grasps that a "relation holds between the terms, which would allow for absolute, universal certainty." Avicenna then adds 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 develops a "method of experimentation as a means for scientific inquiry."
Physics
In mechanics, Ibn Sīnā, in The Book of Healing, developed an elaborate 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.
His theory of motion is thus reminiscent of the theory of inertia, now known as Newton's first law of motion. His theory of mayl also attempted to provide a quantitive relation between the weight and velocity of a moving body, resembling the concept of momentum, a precursor to the concept of momentum in Newton's second law of motion. Ibn Sīnā's theory of mayl was further developed by Jean Buridan in his theory of impetus.
In optics, Ibn Sina "observed 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:
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 simply 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:
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"). The main thesis of these tracts is represented in his so-called "flying man" argument, which resonates with what was centuries later entailed by Descartes's cogito argument (or what phenomenology designates as a form of an "epoche").
Avicennian philosophy
Ibn Sīnā 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 - which was the de facto scientific language of that time, and some were written in the Persian language. Of linguistic significance even to this day are a few books that he wrote in nearly pure Persian language (particularly the Danishnamah-yi 'Ala', Philosophy for Ala' ad-Dawla'). Ibn Sīnā's commentaries on Aristotle often corrected the philosopher, encouraging a lively debate in the spirit of ijtihad.
In the medieval Islamic world, due to Avicenna's successful reconciliation between Aristotelianism and Neoplatonism along with Kalam, Avicennism eventually became the leading school of Islamic philosophy by the 12th century, with Avicenna becoming a central authority on philosophy.
Avicennism was also influential in medieval Europe, particular his doctrines on the nature of the soul and his existence-essence distinction, along with the debates and censure that they raised in scholastic Europe. This was particularly the case in Paris, where Avicennism was later proscribed in 1210. Nevertheless, his psychology and theory of knowledge influenced William of Auvergne and Albertus Magnus, while his metaphysics had an impact on the thought of Thomas Aquinas.
Metaphysical doctrine
Early Islamic philosophy and Islamic metaphysics, imbued as it is with Islamic theology, distinguishes more clearly than Aristotelianism the difference between essence and existence. Whereas existence is the domain of the contingent and the accidental, essence endures within a being beyond the accidental. The philosophy of Ibn Sīnā, particularly that part relating to metaphysics, owes much to al-Farabi. The search for a truly definitive Islamic philosophy can be seen in what is left to us 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 (Mahiat) and existence (Wujud). He argued that the fact of existence can not 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.
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 The Necessary exists ‘due-to-Its-Self’, and has no quiddity/essence (mahiyya) other than existence (wujud). 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. However, if no differentia distinguishes them from each other, then there is no sense in which these ‘Existents’ are not one and 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).
Natural philosophy
Ibn Sina and Abū Rayhān al-Bīrūnī engaged in a written debate, with Abu Rayhan Biruni mostly criticizing Aristotelian natural philosophy and the Peripatetic school, while Avicenna and his student Ahmad ibn 'Ali al-Ma'sumi respond to Biruni's criticisms in writing. Abu Rayhan began by asking Avicenna eighteen questions, ten of which were criticisms of Aristotle's On the Heavens.
Theology
Ibn Sīnā 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 wrote a number of treatises dealing with Islamic theology. These included treatises on the Islamic prophets, whom he viewed as "inspired philosophers", and on various scientific and philosophical interpretations of the Qur'an, such as how Quranic cosmology corresponds to his own philosophical system.
Ibn Sīnā memorized the Qur'an by the age of seven, and as an adult, he wrote five treatises commenting on suras from the Qur'an. One of these texts included the Proof of Prophecies, in which he comments on several Quranic verses and holds the Qur'an in high esteem. Avicenna argued that the Islamic prophets should be considered higher than philosophers.
Thought experiments
While he was imprisoned in the castle of Fardajan near Hamadhan, Avicenna wrote his famous "Floating Man" thought experiment to demonstrate human self-awareness and the substantiality of the soul. He 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. His "Floating Man" thought experiment tells its readers to imagine themselves suspended in the air, isolated from all sensations, which includes no sensory contact with even their own bodies. He argues that, in this scenario, one would still have self-consciousness. He thus concludes 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.
Other contributions
Astronomy and astrology
The study of astrology was refuted by Avicenna. His reasons were both due to the methods used by astrologers being conjectural rather than empirical and also due to the views of astrologers conflicting with orthodox Islam. He also cited passages from the Qur'an in order to justify his refutation of astrology on both scientific and religious grounds.
In astronomy, he criticized Aristotle's view of the stars receiving their light from the Sun. Ibn Sīnā stated that the stars are self-luminous, and believed that the planets are also self-luminous. He claimed to have observed the transit of Venus across the Sun on May 24, 1032. However, modern scholars have questioned whether he could have observed the transit from his location at that time. He used his transit observation to demonstrate that Venus was, at least sometimes, below the Sun in the Ptolemaic cosmology.
Soon after, he wrote the Compendium of the Almagest, a commentary on Ptolemy's Almagest. Avicenna concluded that Venus is closer to the Earth than the Sun. In 1070, Abu Ubayd al-Juzjani, a pupil of Ibn Sīnā, claimed that his teacher Ibn Sīnā had solved the equant problem in the Ptolemaic model.
Chemistry
In chemistry, the chemical process of steam distillation was first described by Ibn Sīnā. The technique was used to produce alcohol and essential oils; the latter was fundamental to aromatherapy. He also invented the refrigerated coil, which condenses the aromatic vapours. This was a breakthrough in distillation technology and he made use of it in his steam distillation process, which requires refrigerated tubing, to produce essential oils.
As a chemist, Avicenna was one of the first to write refutations on alchemy, after al-Kindi. Four of his works on the refutation of alchemy were translated into Latin as:
- Liber Aboali Abincine de Anima in arte Alchemiae
- Declaratio Lapis physici Avicennae filio sui Aboali
- Avicennae de congelatione et conglutinatione lapifum
- Avicennae ad Hasan Regem epistola de Re recta
In one of these works, Ibn Sīnā discredited the theory of the transmutation of substances commonly believed by alchemists:
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.
Among his works refuting alchemy, Liber Aboali Abincine de Anima in arte Alchemiae was the most influential, having influenced later medieval chemists and alchemists such as Vincent of Beauvais.
In another work, translated into Latin as De congelatione et conglutinatione lapidum, Ibn Sina proposed a four-part classification of inorganic bodies, which was a significant improvement over the two-part classification of Aristotle (into orycta and metals) and three-part classification of Galen (into terrae, lapides and metals). The four parts of Ibn Sina's classification were: lapides, sulfur, salts and metals.[verification needed]
Engineering
In the chapters on mechanics and engineering in his encyclopedia Mi'yar al-'aql (The Measure of the Mind), Avicenna writes an analysis on the ilm al-hiyal (science of ingenious devices) and makes the first successful attempt to classify simple machines and their combinations. He first describes and illustrates the five constituent simple machines: the lever, pulley, screw, wedge, and windlass. He then analyzes all the combinations of these simple machines, such as the windlass-screw, windlass-pulley and windlass-lever for example. He is also the first to describe a mechanism which is essentially a combination of all of these simple machines (except for the wedge).[79][not in citation given]
Poetry
Almost half of Ibn Sīnā'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:
از قعر گل سیاه تا اوج زحل
کردم همه مشکلات گیتی را حل
بیرون جستم زقید هر مکر و حیل
هر بند گشاده شد مگر بند اجل
Up from Earth's Centre through the Seventh Gate,
I rose, and on the Throne of Saturn sate,
And many Knots unravel'd by the Road,
But not the Master-Knot of Human Fate.
When some of his opponents blame him for blasphemy, he says
کفر چو منی گزاف و آسان نبود
محکمتر از ایمان من ایمان نبود
در دهر یکی چون من و آن هم کافر
پس در همه دهر یک مسلمان نبود
The blasphemy of somebody like me is not easy and exorbitant,
There isn't any stronger faith than my faith,
If there is just one person like me in the world and that one is impious,
So there are no Muslims in the whole world.
Legacy
As early as the 14th century when Dante Alighieri showed him experiencing a perfect eternity with some of the greatest men in history 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 history's great figures.
George Sarton, the author of The History of Science, described Ibn Sīnā 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. He was influenced by the approach of Hippocrates and Galen, as well as Sushruta and Charaka. Along with Rhazes, Abulcasis, Ibn al-Nafis, and al-Ibadi, Ibn Sīnā is considered an important compiler of early Muslim medicine. He is remembered in Western history of medicine as a major historical figure who made important contributions to medicine and the European Renaissance. Ibn Sīnā is also considered the father of the fundamental concept of momentum in physics.
In Iran, he is considered a national icon, and is often regarded as one of the greatest Persians to have ever lived. Many portraits and statues remain in Iran today. An impressive monument to the life and works of the man who is known as the 'doctor of doctors' still stands outside the Bukhara museum and his portrait hangs in the Hall of the Avicenna Faculty of Medicine in the University of Paris. There is also a crater on the Moon named Avicenna. Bu-Ali Sina University in Hamedan (Iran), the ibn Sīnā Tajik State Medical University in Dushanbe (The capital of the Republic of Tajikistan), Ibn Sina Academy of Medieval Medicine and Sciences at Aligarh, India, Avicenna School in Karachi and Avicenna Medical College in Lahore Pakistan, Ibne Sina Balkh Medical School in his native province of Balkh in Afghanistan, and Ibn Sina Integrated School in Marawi City (Philippines) are all named in his honour.
In 1980, the former Soviet Union, which then ruled his birthplace Bukhara, celebrated the thousandth anniversary of Avicenna's birth by circulating various commemorative stamps with artistic illustrations, and by erecting a bust of Avicenna based on anthropological research by Soviet scholars. Near his birthplace in Qishlak Afshona, some 25 km (16 mi). north of Bukhara, a training college for medical staff has been named for him. On the grounds is a museum dedicated to his life, times and work. GoogleEarth: SEE.
In March 2008, it was announced that Avicenna’s name would be used for new Directories of education institutions for health care professionals, worldwide. The Avicenna Directories will list universities and schools where doctors, public health practitioners, pharmacists and others, are educated. The project team stated “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.”
Works
Scarcely any member of the Muslim circle of the sciences, including theology, philology, mathematics, astronomy, physics, and music, was left untouched by the treatises of Ibn Sīnā. This vast quantity of works - be they full-blown treatises or opuscula - vary so much in style and content (if one were to compare between the 'ahd made with his disciple Bahmanyar to uphold philosophical integrity with the Provenance and Direction, for example) that Yahya (formerly Jean) Michot has accused him of "neurological bipolarity".
Ibn Sīnā's 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, a vast philosophical and scientific encyclopaedia, and The Canon of Medicine,
Ibn Sīnā wrote at least one treatise on alchemy, but several others have been falsely attributed to him. His book on animals was translated by Michael Scot. His Logic, Metaphysics, Physics, and De Caelo, are treatises giving a synoptic view of Aristotelian doctrine, though the Metaphysics demonstrates a significant departure from the brand of Neoplatonism known as Aristotelianism in Ibn Sīnā's world; Arabic philosophers have hinted at the idea that Ibn Sīnā 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 printed more than once, 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 encyclopaedic 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 Ibn Sina'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 حكمت مشرقيه (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.
List of works
This is the list of some of Avicenna's well-known works:
- Sirat al-shaykh al-ra’is (The Life of Ibn Sina), ed. and trans. WE. Gohlman, Albany, NY: State University of New York Press, 1974. (The only critical edition of Ibn Sina’s autobiography, supplemented with material from a biography by his student Abu ‘Ubayd al-Juzjani. A more recent translation of the Autobiography appears in D. Gutas, Avicenna and the Aristotelian Tradition: Introduction to Reading Avicenna’s Philosophical Works, Leiden: Brill, 1988.)
- Al-Isharat wa-‘l-tanbihat (Remarks and Admonitions), ed. S. Dunya, Cairo, 1960; parts translated by S.C. Inati, Remarks and Admonitions, Part One: Logic, Toronto, Ont.: Pontifical Institute for Mediaeval Studies, 1984, and Ibn Sina and Mysticism, Remarks and Admonitions: Part 4, London: Kegan Paul International, 1996.
- Al-Qanun fi’l-tibb (The Canon of Medicine), ed. I. a-Qashsh, Cairo, 1987. (Encyclopedia of medicine.)
- Risalah fi sirr al-qadar (Essay on the Secret of Destiny), trans. G. Hourani in Reason and Tradition in Islamic Ethics, Cambridge: Cambridge University Press, 1985.
- Danishnama-i ‘ala’i (The Book of Scientific Knowledge), ed. and trans. P Morewedge, The Metaphysics of Avicenna, London: Routledge and Kegan Paul, 1973.
- Kitab al-Shifa’ (The Book of Healing). (Ibn Sina’s major work on philosophy. He probably began to compose al-Shifa’ in 1014, and completed it in 1020.) Critical editions of the Arabic text have been published in Cairo, 1952–83, originally under the supervision of I. Madkour
- Kitab al-Najat (The Book of Salvation), trans. F. Rahman, Avicenna’s Psychology: An English Translation of Kitab al-Najat, Book II, Chapter VI with Historical-philosophical Notes and Textual Improvements on the Cairo Edition, Oxford: Oxford University Press, 1952. (The psychology of al-Shifa’.)
- Hayy ibn Yaqdhan a Persian myth. A novel called Hayy ibn Yaqdhan, based on Avicenna's story, was later written by Ibn Tufail (Abubacer) in the 12th century and translated into Latin and English as Philosophus Autodidactus in the 17th and 18th centuries respectively. In the 13th century, Ibn al-Nafis wrote his own novel Fadil ibn Natiq, known as Theologus Autodidactus in the West, as a critical response to Hayy ibn Yaqdhan.
Persian Works
Danishnama-i ‘Alai
Danishnama-i ‘Alai is called "the Book of Knowledge for [Prince] 'Ala ad-Daulah". One of Avicenna's important Persian work is the Daaneshnaame (literally: the book of knowledge) for Prince 'Ala ad-Daulah (the local Buyid ruler). The linguist aspects of the Dāneš-nāma and the originality of their Persian vocabulary are of great interest to Iranian philologists. Avicenna created new scientific vocabulary that had not existed before in the modern Persian language. The Dāneš-nāma covers such topics as logic, metaphysics, music theory and other sciences of his time. This book has translated to English by Parwiz Mowewedge.
Andar Danesh-e-Rag
Andar Danesh-e-Rag is called "On the science of the pulse". This book contains nine chapters on the science of the pulse and is condensed synonpsis.
Persian Poetry
Persian poetry from Ibn Sina is recorded in various manuscripts and later anthologies such as Nozhat al-Majales.
