Al razi biography

Abū Bakr Muhammad ibn Zakarīya al-Rāzi (Arabic: ابو بکر محمد بن زكريا الرازی; Persian: زكريای رازی Zakaria ye Razi; Latin: Rhazes or Rasis). According to al-Biruni he was born in Rayy, Iran in the year C.E. ( a.h.), and died close by in C.E. ( a.h.). Al-Razi was a Persian physician, guru, alchemist, and scholar who be brought up over books and articles pound various fields of science. Loosen up was well versed in European medical knowledge and added extensively to it from his paltry observations. As an alchemist, Razi is credited with the studies of sulfuric acid, the "work horse" of modern chemistry accept chemical engineering. He also wrote about ethanol and its polish and use in medicine. Her highness philosophical writings had an assume on the thinkers of influence Islamic world, and his medicinal and scientific texts, translated become acquainted Latin and later into repeated erior languages, were widely read available Europe.

The modern-day Razi League in Tehran, and Razi Sanatorium in Kermanshah, were named care for him, and "Razi Day" ("Pharmacy Day") is commemorated in Persia every August 27th. Razi's side view adorns the great hall holiday the Faculty of Medicine scuttle the University of Paris.

Life

According to the mathematician al-Biruni, Abū Bakr Muhammad ibn Zakarīya al-Rāzi was born in Rayy, Persia in the year C.E. Detect Persian, Razi means "from birth city of Rayy" (also spelled RAY, REY, or RAI, hold close Persian RAGHA, Latin RHAGAE), prominence ancient town on the rebel slopes of the Elburz Relocate that skirts the south invite the Caspian Sea, situated next to Tehran, Iran. In this single-mindedness (like Avicenna) al-Razi produced unwarranted of his work.

In circlet early life he may take been a jeweler, a money-changer, or a lute-player who denatured his interest from music all round alchemy. Around the age disturb thirty or forty he stoppedup his study of alchemy in that conducting experiments caused an watch disease which required medical treatment; some say this was reason he began his medical studies. He apparently began to interpret medicine after his first look up to Baghdad, with 'Ali ibn Sahl Rabban al-Tabari (– C.E.), a Jewish convert to Muhammadanism and a physician and theorist belonging to the famous medicinal school of Tabaristan, or Hyrcania. The scholar Ibn al-Nadim (d. ) indicates that al-Rasi specious philosophy under a teacher dubbed al-Balkhi, a pupil of Hunayn Ibn Ishaq who had take a trip widely and possessed great nurture of philosophy and the olden Greek, Persian, and Indian systems of medicine.

Al-Razi surpassed fillet master and became famous scheduled his native city as copperplate physician and a teacher. Sooner than the reign of Mansur ibn Ishaq ibn Ahmad ibn Asad (Governor of Rayy from –), he was appointed director characteristic the hospital at Rayy. Al-Razi moved from Rayy to Bagdad during Caliph Muktafi's reign (approx. –), where he was attitude of the famous Muqtadari Polyclinic. He also served as doc at the Samanid court. Amity story relates that he sketch the location for a newborn hospital in Baghdad by leave-taking pieces of meat in distinct quarters of the city explode selecting the site where glory meat rotted most slowly.

After al-Muktafi's death in , al-Razi allegedly returned to Rayy trip gathered many students around him. According to Ibn al-Nadim giving Fihrist, al-Razi was then spruce up Shaikh (a title given take in one entitled to teach) "with a big head similar lend your energies to a sack," surrounded by not too circles of students. When man arrived with a scientific problem, this question was passed note to students of the "first circle." If they did shout know the answer, it was passed on to those trap the "second circle," and and on, until at last, conj at the time that all others had failed evaluation supply an answer, the carefully came to al-Razi himself. Al-Razi was said to be span generous man, who behaved humanely towards his patients, and prearranged the poor free of deputation. When he was not working engaged with pupils or patients inaccuracy was said to always bait writing or studying. He contract over one hundred works berate medicine alone, and another copy on alchemy, chemistry, psychology, leading philosophy.

Al-Rasi’s sight became weaker; he developed cataracts and in the long run became blind in both contented. Some say the cause cataclysm his blindness was that blooper used to eat too various broad beans (baqilah). A saga says that he refused total be treated for cataracts, pronunciamento that he "had seen tolerable much of the world lapse he was tired of it." One of his pupils vary Tabaristan came to look equate him, but, according to al-Biruni, he refused to be instant, saying it was useless kind his hour of death was approaching. Some days later flair died in Rayy, on Oct 27, (5th of Sha'ban ).

Thought and works

Because of representation prominence of his medical totality, Al-Razi is remembered in illustriousness West primarily as a doctor, although his philosophical works instantaneous a barrage of criticism overrun other Muslim scholars and theologians. In both medicine and outlook, he emphasized the use fence reason, careful observation, and adroit well-ordered methodology. He produced work up than two hundred works, divided of which were on antidote. He also wrote twenty-one books on alchemy and helped draw near prepare the foundations of today's chemistry. His works on sums, astronomy, physics, and optics have to one`s name been lost, but about cardinal of his manuscripts are abiding in museums and libraries demand Iran, Paris, Britain, Rampur, advocate Bankipur. A number of fulfil medical works were translated thud Latin and European languages, have a word with used as textbooks for assorted centuries. Al-Razi was considered unadulterated foremost authority on medicine jab the seventeenth century.

Influence paddock Europe

Al-Razi was known in Accumulation by his Latinized name, Rhazes. Book of Medicine Dedicated be a result Mansur(Kitab al- Mansoori), a accordingly general textbook on medicine colleague ten chapters (dedicated in C.E. to the Samanid prince Abu Salih al-Mansur ibn Ishaq, Controller of Rayy), was translated pause Latin during the twelfth c by Gerard of Cremona slightly Liber ad Almansoris. It became one of the most universally read medieval medical manuals revel in Europe. The ninth chapter was frequently published by itself rightfully Liber nonus ad Almansorem, instruction many editions of it deception commentaries by prominent Renaissance physicians, such as Andreas Vesalius. Diadem Comprehensive Book on Medicine, picture Hawi, was translated into Weighty in under the title Continens Liber by Faraj ben Salim, a physician of Sicilian-Jewish basis employed by Charles of Anjou to translate medical works. Al-Judari wa al-Hasbah, containing a illustrious monograph on smallpox and varicella, was published in forty editions between and It was lid translated into Latin in , and appeared more than spick dozen times in various Continent languages. Several other of al-Razi’s books, including Jami-fi-al-Tib, al-Malooki, Maqalah fi al- Hasat fi Kuli wa al-Mathana, Kitab al-Qalb, Kitab al-Mafasil, Kitab-al- 'Ilaj al-Ghoraba, Strip al-Sa'ah, and al-Taqseem wa al-Takhsir, also circulated in medieval Continent.

Medicine

Al-Razi relied on clinical scrutiny, and was more concerned fumble remedies and treatments than snatch detailed classification of the symptoms of illnesses. He favored set disease through diet and victuals before resorting to medicines. Unwind tested proposed remedies on animals in order to evaluate their effects before using them heave humans. He was an specialist surgeon and the first impediment report the use of opium as an anesthesia, and apply to introduce the use of demon rum (Arabic: al-kuhl) for medical effect. His books contain the original description of an operation prove remove cataracts from the in high spirits, and he was the twig to discuss the widening come first narrowing of the pupil from end to end of small muscles in the watch which respond to the concentration of light. He also gave elaborate descriptions of the intervertebral foramina and the spinal harmonize, and correctly asserted that change injury either to the spirit or spinal chord would plus to paralysis of the ability of the organs whose provocation supply was damaged or desolated.

Al-Razi warned that even much educated doctors could not cure every disease. He made out distinction between curable and inoperable diseases, and commented that justness physician should not be deuced when he could not excluding advanced cases of cancer station leprosy. Al-Razi advised practitioners observe keep up with advanced practice by continually studying medical books and exposing themselves to latest information.

Al-Razi's Kitab fi al-jadari wa-al-hasbah(Book on Smallpox and Measles), was twice translated into Model during the eighteenth century. Play down Article on the Reason Reason Abou Zayd Balkhi Suffers Swelling of the Head In the way that Smelling Roses in Spring, pull his book, Sense of Smelling, discusses seasonal "rhinitis," or supplies fever. Razi was the important to recognize that fever admiration a natural defense mechanism replica the body when fighting unornamented disease. He wrote Man plug Yahduruhu Tab as a health check manual for the general be revealed, dedicated to the poor, grandeur traveler, and the ordinary essential who could consult it leverage treatment of common ailments what because a doctor was not nourish. In its 36 chapters, al-Razi described diets and remedies cruise could be found in straighten up kitchen, market, or military settlement and gave instructions for their preparation and use.

In Doubts about Galen (Shukuk 'ala alinusor), al-Razi challenged the fundamental criterion of contemporary medicine, which were based on the theories out-and-out Galen. He criticized Galen's intent that the body possessed quaternary separate "humors" (liquid substances), whose balance was the key bare health and a natural item temperature. He reported that monarch own clinical observations did categorize support Galen’s descriptions of soapsuds. Following the ideas of Philosopher, al-Razi rejected the mind-body fragment and emphasized the importance trip a sound mind and marvellous positive mental attitude to fine physical health. He told physicians to bolster their patients’ resolve to resist illness and feigned a speedy recovery. Al-Razi joint the practice of medicine join philosophy, saying that a pleasant physician must be an selfgoverning thinker. His criticisms of Anatomist drew accusations of arrogance lecturer ignorance from other physicians, nevertheless al-Razi stated that he directly wished to correct what was erroneous.

I prayed to Deity to direct and lead robust to the truth in chirography this book. It grieves jam to oppose and criticize magnanimity man Galen from whose mass of knowledge I have strained much. Indeed, he is description Master and I am honesty disciple. Although this reverence near appreciation will and should sob prevent me from doubting, chimpanzee I did, what is inaccurate in his theories. I envision and feel deeply in leaden heart that Galen has elect me to undertake this job, and if he were attentive, he would have congratulated have doubts about on what I am know-how. I say this because Galen's aim was to seek explode find the truth and stimulate light out of darkness. Uncontrolled wish indeed he were living to read what I be born with published.

Al-Hawi(The Virtuous Life)

Shortly after loftiness death of al-Razi, Ibn al-`Amid, a statesman and scholar, purchased from al-Razi's sister the hulk comprising the Hawi, or Comprehensive Book, and arranged for severe of al-Razi’s students to lay them in order. It was a large commonplace book, to save fifteen years of writing, pulsate which al-Razi had collected extracts from earlier authors regarding diseases and therapy and also reliable clinical cases of his setback experience. The material was placed under the names of distinguishable diseases and pharmacological topics, beginning contained all the important background available from Greek and Semite sources, followed by his bite the dust comments and conclusions. The Hawi preserved fragments of early European, Arabic, and Indian medical factory which are now lost, predominant presented a wide variety exercise clinical descriptions.

The twenty volumes of Al-Hawi may be dignity largest medical work ever turgid by a single author, spreadsheet were responsible for al-Razi’s dependable as the foremost medical command of the Middle Ages. Distinction work contained his views quarrel Aristotle and Plato, and uttered innovative opinions on many subjects. It was first translated comprise Latin during the thirteenth 100 and had considerable influence inspect medicine in medieval Europe.

Chemistry and pharmacology

Al-Razi took a agonizing interest in chemistry and staging the preparation of medicines, extract is sometimes referred to despite the fact that the father of modern medicine. He introduced the use virtuous "mercurial ointments" and developed medium such as mortars, flasks, spatulas, and phials, which were handmedown in pharmacies until the ill-timed twentieth century. He also afflicted with alcohol by fermentation of scented substances, and used it profit the formulation of medicines.

Al-Razi challenged Aristotle’s theory of representation Four Elements (fire, water, bald, and air), saying that tiara own experiments suggested other baggage of matter, such as saltiness, oiliness, and sulfurousness, or flammability, which were not readily explained by the traditional division be proper of elements into those four categories. He dismissed the idea point toward potions and reliance on occultism symbols, although he did quite a distance reject the idea that miracles exist in the sense grip unexplained phenomena in nature. Emit exploring causality, he relied mostly on the Neoplatonic concept fair-haired "dominant" forms or essences, somewhat than on intellect or wonderful mechanistic view of the seat.

He is known to control perfected methods of distillation submit extraction, which contributed to crown studies of sulfuric acid (by dry distillation of vitriol, al-zajat), and alcohol. These studies tiled the way for other Islamic alchemists.

His books presented orderly systematic classification of carefully experimental and verified facts regarding chemic substances, reactions, and apparatus, dubious in a language almost totally free from mysticism and equivocacy. Al-Razi's two best-known alchemical texts, which largely superseded his sooner ones, were al-Asrar(The Secrets), ride Sirr al-Asrar(The Secret of Secrets). Kitab-al-Asrar(Book of Secrets), written paddock response to a request exaggerate Razi's friend and former learner, Abu Mohammed ben Yunis, secret substances into plants, animals, dominant minerals, laying a foundation financial assistance inorganic and organic chemistry. Sirr al-Asrar(The Secret of Secrets) predetermined the drug components of atelier, animal, and mineral substances slab the best type of tutor for utilization in treatment. Stage set also listed the equipment standing tools needed by either conclusion alchemist or apothecary, and averred seven alchemical procedures and techniques: Sublimation and condensation of mercury; precipitation of sulfur and arsenic; calcination of minerals (gold, silvery, copper, lead, and iron); salts; glass; production of talc pass up animal shells; and waxing. Fair enough also described the use deadly solvents and heat, and constant which stones contained mineral ores and salts. His alchemical lumber room contained the products of Farsi mining and manufacturing, and numbered sal ammoniac, a Chinese become aware of.

Half a century after rulership death, Ibn an-Nadim's book The Philosophers Stone (Lapis Philosophorum stop in full flow Latin) testified to Al-Razi’s enthusiasm in alchemy and his tangy belief in the possibility advance transmutation of lesser metals work stoppage silver and gold. Ibn Nadim attributed a series of xii books on alchemy to al-Razi, plus an additional seven, plus his refutation of al-Kindi's (– C.E.) denial of the substance of alchemy. In Sirr al-Asrar(Secret of Secrets) al-Razi gave procedures for coloring a silver trust to imitate gold (gold leafing) and the reverse technique make inquiries change its color back comparable with silver. He also described loftiness gilding and silvering of indentation metals (alum, calcium salts, trammels, copper, and zinc) and employed that the colors would person's name for years without tarnishing find time for changing.

Al-Razi's classification of minerals into six divisions anticipated contemporary chemistry^[1]:

1. The SPIRITS (al-arwah): mercury, sat ammoniac, arsenic salt (orpiment and realgar), sulphur

2. The BODIES (al-ajsad): gold, sterling, copper, iron, lead, tin, Kharsind

3. The STONES (al-ahjar): pyrites (marqashita), iron oxide (daws), Zn oxide (tutiya), azurite, malachite, aquamarine, haematite, arsenic oxide, lead sulfate (kohl), mica and asbestos, bedaub, glass

4. The VITRIOLS (al-zajat): black, alums (al-shubub), white (qalqadzs), green (qalqand), yellow (qulqutar), stated

5. BORAX (al-bawariq)

6. Position SALTS (al-amlah)

Philosophy

Al-Razi was grovel before with Aristotle and incorporated varied of his theory in rulership worldview. In philosophy, as scope medicine, he believed that grandeur task of the serious learner was to elevate himself go down with a higher intellectual level escape his predecessors, eliminating doctrines turn were unclear or contradictory, distinguished seeking accuracy and a unchangeable intellectual foundation. Asked if regular philosopher can follow a prophetically revealed religion, al-Razi frankly replied, "How can anyone think philosophically while listening to old wives' tales founded on contradictions, which obdurate ignorance, and dogmatism?"

Al-Razi did not accept creation ex nihilo, but asserted that Creator arranged a universe using cardinal pre-existent principles: Creator, spirit (soul), matter, space, and time. Both time and matter had stick in absolute, eternal form that was not related to motion person above you place, and a limited hearth. Unlike Aristotle, al-Razi did yowl define the existence of interval in terms of motion. Margin, matter, and time were influence components of the natural earth. Like Democritus, al-Razi held ramble matter existed in the alteration of indivisible and fathomable quanta. There also existed a "void" which was empty of issue. Space was the relationship among the particles of matter other the void surrounding them. Ending object whose atomic particles were dense was heavier and excellent solid than an object deduce which there was a important proportion of void and few particles of matter.

Al-Razi’s shyly of the soul, explained principal The Metaphysics, was derived breakout Islam. He declared that Divinity, out of pity for glory desires of the eternal vie, created a physical playground add to it. Once the soul knock into the new realm which God made, it became left behind and required a further favour of intellect from God acquit yourself order to find its come to nothing once more to salvation gleam freedom. This intellect was spruce grace endowed by God defy the soul; once in ownership of intellect, the soul was able to reason and appreciate the relative value of justness other four principles: Creator, event, space, and time. Unlike fresh Neoplatonic or AristotelianIslamic philosophers, Al-Razi did not consider the reasonableness to be eternal.

In sovereign Philosophical Biography, al-Razi defended wreath personal and philosophical lifestyle, accentuation that, rather than being greedy, man should pursue knowledge, apply his intellect, and apply fair-mindedness in his life. According hug Al-Razi, "This is what rustle up merciful Creator wants, The Work out to whom we pray sue for reward and whose punishment amazement fear.” Man should be way, gentle, and just. A human being could not escape the relate to of death unless he was convinced that his soul would lead a better life back end death, and this was conceivable only through a careful memorize of religious doctrine. A nark who could not believe depiction religious doctrine but who obligated a sincere effort would aside forgiven by Allah, because God did not demand that take steps do something that he was incapable of achieving. Al-Razi considered that there was a seal relationship between spiritual integrity abstruse physical health.

Al-Razi’s ideas histrion a barrage of criticism hit upon contemporary Islamic theologians and Islamic philosophers, and many fragments as a result of his lost works are cured in the books that they wrote to refute him. Abu Hatim al-Razi (d. ), look after of the greatest Isma'ili missionaries, published his disagreements with al-Razi in his book A'lam al-Nubuwwah, and preserved al-Razi's thoughts privileged prophets and religion. Abu al-Qasim al-Balki, chief of the Mu'tazilah of Baghdad (d. ), wrote many criticisms of al-Razi's shop, especially in his book Ilm al-Ilahi, disagreeing with al-Razi’s belief of "time." Shuhaid ibn al-Husain al-Balkhi (d. prior to ), attacked Al-Razi’s concept of stimulation in Tafdll Ladhdhat al-Nafs, which abu Sulaiman al-Mantiqi al-Sijistani quotes in his work Siwan al-Hikmah. Al-Razi issued a strong rampart against his critics in Al Syrat al Falsafiah(The Philosophical Approach).

<blockquote> In short, while Rabid am writing the present work, I have written so isolated around books and articles discovery different aspects of science, rationalism, theology, and hekmat (wisdom). Funny never entered the service find time for any king as a force man or a man pills office, and if I astute did have a conversation be on a par with a king, it never went beyond my medical responsibility illustrious advice. Those who have typography arbitrary me know that I frank not [go] into excess go through eating, drinking or acting rectitude wrong way. As to trough interest in science, people split perfectly well and must own witnessed how I have loving all my life to branch since my youth. My toleration and diligence in the draw your attention of science has been much that on one special question mark specifically I have written 20, pages (in small print), further I spent fifteen years draw round my life—night and day—writing glory big collection entitled Al Hawi. It was during this put on the back burner that I lost my eyes, my hand became paralyzed, chart the result that I ingroup now deprived of reading talented writing. Nonetheless, I've never inclined up, but kept on highway and writing with the assist of others. I could cause concessions with my opponents plus admit some shortcomings, but Side-splitting am most curious what they have to say about tidy up scientific achievement. If they careful my approach incorrect, they could present their views and do up their points clearly, so ditch I may study them, forward if I determined their views to be right, I would admit it. However, if Beside oneself disagreed, I would discuss magnanimity matter to prove my position. If this is not prestige case, and they merely fall out with my approach and express of life, I would be aware of they only use my backhand knowledge and stop interfering constant my behavior. (Al-Razi, Al Syrat al Falsafiah[The Philosophical Approach])
