This article offers the first edition and translation of two heretofore unpublished pharmacological treatises by Abū Bakr al-Rāzī, namely Fī ittikhādh māʾ al-jubn and Fī manāfiʿ māʾ al-jubn, which seem to have formed part of a lost volume on dairy products. As it demonstrates, al-Rāzī’s examination of whey is connected to his philosophical interest in the complex nature of simple substances such as milk. The article also highlights how these two treatises built on the Greek pharmacological tradition by incorporating (...) ingredients from Persia and India. (shrink)

As there are several famous al-Rāzī relevant to philosophy, I need first to specify that this remarkable book deals with Abū Bakr Muhammad ibn Zakariyyā' al-Rāzī, also known as "Galen of the Arabs," and in Latin as well as in the Canterbury Tales as "al-Rhazes." He proudly presented himself as both a philosopher and a physician taking Galen as his model. Just as in Hellenistic times Galen was highly valued as a physician but demeaned as a philosopher, so (...) often was al-Rāzī. This book reinstates al-Rāzī as an interesting philosopher, who claims to be a disciple of Galen and Plato but clearly understands that discipleship implies following Galen's own example of avoiding uncritical...

Abū Bakr Muḥammad bin Zakariyya’ al-Rāzī (865–925) is generally known as a freethinker who argued against prophecy and revealed religion based on arguments from fairness of God and rationality. Recently some scholars argued that Razi was not as radical as the general interpretation takes him to be. Both the freethinker and conservative interpretations seem well supported based on difference bodies of evidence. However, the evidence is based on secondhand reports. In this paper I argue there is an (...) interpretation of prophecy which is supported by primary sources and can reconcile these putatively contradictory positions. Under my interpretation Razi allows for prophecy based on the rationality of moral deference in certain circumstances. In this picture one function of prophets is to act as moral experts for deference. This interpretation provides a synthesis of the freethinker and conservative views. Razi is conservative in having room for prophecy because of his dualist nature of humanity, and Razi is still a freethinker who values reason above all, because moral expertise requires excellent command of reason.

This paper initiates a dialogue between classical Islamic philosophy and late modern European thought, by focusing on two peripheral, ‘heretical’ figures within these traditions: Abū Bakr Muḥammad ibn Zakariyāʾ al-Rāzī and Friedrich Nietzsche. What affiliates these thinkers across the cultural and historical chasm that separates them is their mutual fascination with, and profound indebtedness to, ancient Greek and Hellenistic philosophy. Given the specific themes, concerns and doctrines that they appropriate from this common source, I argue that al-Rāzī and Nietzsche (...) should be read as Epicureans and seen in relation to their predecessor as part of the subterranean tradition of philosophical naturalism. However, while each figure appropriates the philosophy of Epicurus, they ultimately transform it in important ways: al-Rāzī offers us a qualified “Platonic” Epicureanism, while Nietzsche forges a radicalized “Dionysian” Epicureanism. The point of such a comparative examination is twofold. First, analyzing the divergent paths of these “wayward” Epicureans sheds new light on the historical trajectory of naturalism as a philosophical stance (as well as its current prospects and limitations). Second, by initiating a dialogue between the classical Islamic and modern European philosophical traditions, we can better understand the antagonisms and shared concerns between these two horizons, as well as the ambiguities and self-questioning that occur within them.

This paper introduces two newly discovered epistles by the celebrated physician and philosopher Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī. The first epistle addresses the question of why and how clothing can be used both to stay warm and to stay cool, drawing on the Aristotelian tradition of problem literature. The second epistle arises out of a court polemic and treats the question of whether one should consume mulberries after watermelons. This study offers analysis, editions, and translations of these previously (...) unknown epistles, situating them within their broader literary and cultural contexts. (shrink)

Rāzī, Abū Bakr Muḥammad ibn Zakarīyā,865?-925?; criticism and interpretation.

Ethics plays an essential role in the philosophical framework of Abū Bakr al-Rāzī. Although most of his philosophical works have become extinct, two surviving works serve as primary sources for understanding his ethical theory. Although sharing certain foundational principles, these two works diverge in terms of ethical standards and exhibit distinct logical approaches to ethics, a facet that has largely remained unexplored within contemporary scholarly discourse. I aim to extract and reconstruct both of his ethical decision-making systems by shedding (...) light on the place of ethics in his philosophy, explaining the interconnection of the two ethical frameworks, reconstructing both of these ethical systems, and finally presenting them in patterns.

In lieu of an abstract, here is a brief excerpt of the content:A Tenth-Century Arabic Interpretation of Plato's Cosmology MAJID FAKIIRY OF PLATO'STHIRTY-SIXDIALOG~Y~Sonly the Timaeus is devoted entirely to cosmological questions. The influence of this dialogue on the development of cosmological ideas in antiquity and the Middle Ages was very great. At a time when the knowledge of Greek philosophy and science in Western Europe had almost vanished, the Timaeus was the only Greek cosmological work to circulate freely in learned (...) circles. The translation and commentary of Chalcidius (c. 350) made the Timaeus available to Latin scholars, at least up to c. 53. But interest in the Timae~s was sustained for a long time before that. The lost commentary of Posidonius of Apamea (d. 51 B.C.), the De animae procreatione in Timeo of Plutarch (d. A.D. 125), the commentary of Proclus (d. 485), extant up to 44d,1 are the most important links in this continuous chain of Platonic cosmological exegesis in antiquity. In the Arabic tradition, the Timaeus had a decisive impact on the development of cosmological ideas also. Plutarch and Proclus were familiar names in the history of Platonic and post-Platonic thought, but I am not aware that the Stoic Posidonius, whom Zeller has described as ".the most universal mind that Greece had seen since the time of Aristotle," 2 was known to the Arabs, or that any mention of his commentary on the Timaeus is to be found in the Arabic sources. General interest in Platonism was an early feature of the philosophical wave which swept the Islamic learned world in the 8th century, and Zeller may be right in saying that it was the Platonic School of Athens which gave Muslim Neoplatonism its peculiar stamp. 3 One of the earliest translators of philosophical texts into Arabic, Yah.ia (b. al-Bit.riq) who flourished in the 2rid half of the 8th century, is credited with the translation of the Timaeus, later retranslated or revised by Hunain (b. Ish~q; d. 873) and Yahia (b. 'Adi and not, as Sarton has it, b. 'Ali; d. 974).~ In addition, the following Platonic dialogues appear to have been translated into Arabic: The Sophistes, the Parmenides, the Cratylus, the Euthydemus, the Republic, the Statesman, the Laws and the Crito. The determination of the actual translator of each work poses serious difficulties. In an autobiographical tract, Hunain simply reports that either he or his disciple Is~ (b. Yahia) translated these works for his patron Muhammad (b. Cf. A. E. Taylor, A Commentary on Plata's Timaeu~ (Oxford, 1928),pp. 34f., and George Sarton, History o] Science (Cambridge, Mass., 1959),I, 428f. Cf. E. Zeller,OutEnesof the History oSGreek Philosophy (N.Y., 1955),p. 268. sIbid., p. 329. ' Cf. al-Fihrist (Cairo, N~D.),p. 358. [15] 16 HISTORY OF PHILOSOPHY Musa), the astrologer.~ Other writers corroborate or supplement this account. Thus Ibn al-Nadim (d. 997), ascribes to Hunain the interpretation (tarsi'r) of the Republic, to him and to Ibn 'Adi the translation of the Laws, and to his son Ish.iq the translation of the Sophistes, together with the commentary of Olympiodorus2 The Crito appears to have been translated also by Yahia (b. Adi), and extensive excerpts from it and the Phaedo are often quoted in the Arabic sources in connection with the trial and execution of Socrates. Another difficulty is raised by the fact that none of the Arabic versions of these dialogues which have come down to us, either as separate works or parts of general commentaries such as the Laws, the Timaeus and the Republic, are complete, so that the inference is inescapable that, as borne out by Hunain's own testimony, it was Galen's paraphrases or compendia of these works, or at any rate those which were translated into Arabic within the School of Hunain, that are actually referred to in our sources.7 It is not, however, with the general diffusion of Platonism in the Muslim world that I am primarily concerned here, but rather with the impact of Platonic cosmological theory as illustrated in the writings of Abu Bakr Muhammad (b. Zakariya al-Razi; d., c. 932), the Rhases of Latin authors, the greatest... (shrink)

This study focuses on the life, works, scholarly personality and place of Abu Bakr Ahmad, one of the pioneers of the science of Qiraat in the Ottoman Empire. Abū Bakr Aḥmad was the son of Ibn al-Jazari, one of the authoritative figures in the science of Qiraat, and the author is called Ibn al-Nāzim after his father. Abū Bakr Aḥmad is an important figure who came to the forefront in the field of Qiraat by being educated by (...) the leading scholars of the period, especially Ibn al-Jazari, and wrote qualified works. Abu Bakr Ahmad distinguished himself among Ibn al-Jazari's other children. Abū Bakr Aḥmad served as a muderris in various madrasas in Damascus, such as the Great Ādiliyya, Atabekiyya and Umayyad mosques, and taught many students throughout his life. Among his students were the children of Bayezid Yildirim. After Ibn al-Jazari came to Bursa, Abu Bakr Ahmad took many books with him and taught what he learned from him to many people, especially the sultan's children. The works written by Abū Bakr Aḥmad also reveal his knowledge of scientific subjects. As a matter of fact, Ibn al-Jazari said that he liked his son Abū Bakr Aḥmad's commentary on Tayyibah very much, “...Although he did not even have a copy of my previous commentary on the same work, he commented it very well. Before that, he had also commented on two poems of mine very well...”. Apart from this commentary, which was praised by Ibn al-Jazari, he also wrote other works. Considering the works of Abū Bakr Aḥmad, it can be said that he was a commentator. This is because most of his works have the quality of a commentary. It is reported that when Ibn al-Nāzim was a professor in the madrasas in Damascus, the chief qadi of the period and many scholars attended his lectures. Ibn al-Nāzim was also the first commentator of Tayyibat al-Nashr, which is used as the main source of Qiraat education both in our country and in other Islamic countries and on which dozens of commentaries have been written. All this reflects the author's knowledge in the field of qiraat.While Abu Bakr Ahmad's personal effort, perseverance and intelligence played an important role in his reaching such a position, the fact that he was the son of a father like Ibn al-Jazari, who left his mark on the history of Qiraat and is considered an authority in his field, was undoubtedly effective. As a matter of fact, Ibn al-Jazari is a valuable figure who came to the forefront among his contemporaries in the shar'i sciences in general and in the field of Qiraat in particular. Aside from the words of praise uttered about him by scholars, the great works he penned and the vibrant community of students he left behind demonstrate this in the best way possible. Abu Bakr Ahmad was one of the first among the students who grew up under the tutelage of such an important scholar. When the studies on the life of Abū Bakr Aḥmad were examined, it was seen that there was no extensive and satisfactory information about the author. In fact, when the sources and documents that directly or indirectly mention the life of the commentator since his time are examined, it is seen that the information in the aforementioned sources is a repetition of what is given in Ibn al-Jazari's Ghāyat al-nihāya and sometimes contains contradictions within itself. For example, many issues such as the date of Abu Bakr Ahmad's death, the number and identity of his siblings, his position as imam-hatip of the Ulucamii, the name of one of his students, Ashraf Musa, the catalog information of some of his works or their attribution to the author are either erroneous or controversial. Nevertheless, sources such as manuscript library catalogs, archival records, and works on the life of Abū Bakr Ahmad such as tabāqat, terājim, and qiraat, academic, modern, or encyclopedic works have been searched, and the information obtained has been compiled and presented in this study. At the same time, the information about his life, which is assumed to be erroneous, has been identified and corrected by going to the main sources, and finally, the correct or close to the truth has been tried to be revealed. The general opinion formed by us as a result of our research on the life of Abu Bakr Ahmad led us to such a study. The main theme of the article is the life of Abū Bakr Ahmad and it is aimed to make a humble contribution to the literature through this study. (shrink)

"Al-Farabi of Baghdad (c. 870-950) is the first major representative of the medieval Arabic Aristotelianism which came to influence the Christian West so profoundly. In the Islamic world his writings on logic set the pattern for the future and virtually created Islamic philosophy. He is also important as a witness to the study of Aristotle in late antiquity, demonstrating a knowledge of Galen and the exegetical tradition of Porphyry. This translation is based on a fresh study of the Arabic manuscripts. (...) An introduction and notes make this intriguing document accessible to all for whom it contains important matter.Classicists, historians of philosophy and logic, medievalists, Arabists, students of Islamic thought."--.

This book studies the phenomenon of freethinking in medieval Islam, as exemplified in the figures of Ibn al-Rāwandī and Abū Bakr al-Rāzī. It reconstructs their thought and analyzes the relations of the phenomenon to Islamic prophetology and its repercussions in Islamic thought.

This article revisits the controversy between Abū Bakr al-Rāzī and Abū al-Qāsim al-Balḫī. Based on the testimony of the Kitāb taṯbīt dalāʾil al-nubuwwa of the Qāḍī ʿAbd al-Ǧabbār, it is shown that the two philosophers must have clashed at the court of Aḥmad b. Sahl al-Marwazī, governor of Balḫ, during the 910s, and that the virulence of the tone of their exchange can be explained above all by this context of professional rivalry. In terms of content, their conversation must (...) have focused on the question of divine justice and on the best way to give an account of prophecy and Qurʾanic wisdom. We then turn to the study of chap. VIII, 4 of Faḫr al-Dīn al-Rāzī's Al-maṭālib al-ʿāliya and show that, contrary to a recently held view, this chapter constitutes an echo not of Abū Bakr al-Rāzī, but of the first argument of Ibn al-Rāwandī's Kitāb al-zumurrud, which contrasted the autonomy of reason with the necessity of prophecy in order to conclude from the former to the negation of the latter. Finally, it is suggested that Abū Bakr al-Rāzī's doctrine of prophecy, like that of the great theologians of his time, both Muʿtazilites and Ašʿarites, aims to escape the dilemma set up by Ibn al-Rāwandī a few decades earlier.

The Buyide wezir Abū I-Faḍl Ibn al-‘Amīd became famous as a poet and expert in epistolary literature, but also as a scholar and scientist. His letters, published here together with translation, commentary and complete glossary, inform us on questions of meteorology, physics, mechanics and psychology.

Extensive scientific, philosophical and artistic activities were carried out in the Islamic World’s various science and civilization centers during the early Middle Ages. In these centers, noteworthy works of mathematics, astronomy, geography, medicine, pharmacology, optics, botany, chemistry and other fields of science, which would later determine improvement paths for these fields, were created. Abu al-Izz Ismail ibn al-Razzaz al-Jazari (12th-13th centuries), was a magnificent Muslim scientist known for his work named The Book of Knowledge of Ingenious Mechanical Devices (Kitab fi (...) ma‘rifati’l-hiyal al-handasiyya) and he was born in geography where many scientists were trained. He contributed to the development of science and civilization, the joint legacy of humanity and demonstrated his true capability and success in the field of ilm al-hiyal (the scientific field which addresses the information and practices regarding mechanical technology and engineering in Islamic science history). From this perspective, it is evident that al-Jazari had a wide field of interest, made his mark in the age he lived in with his brave and innovative ideas, and was a wise engineer. al-Jazari’s detailed descriptions and explanations of water clocks, oil lamp clocks and water pumping machines, as well as their construction, were astounding. In addition, al-Jazari’s studies on metal casting techniques, cone valves, wheel balance and the real-world use of aspiration tubes are important in contemporary engineering studies. When all these are considered, it becomes clear that his designation as the “Leonardo da Vinci of the Islamic World” is not a coincidence. Many studies on al-Jazari’s scientific legacy have been conducted in various parts of the world. There are various manuscripts of his aforementioned book. Based on these manuscripts, the work has been -fully or partially- translated into many languages, including Turkish. The German and English translations served as a basis for studies on al-Jazari in other languages. In recent years, studies conducted on al-Jazari in Türkiye (books, articles, domestic and international symposiums, congresses etc.) have demonstrated his brilliance and competence as a scientist. Furthermore, studies on al-Jazari are still ongoing in Türkiye. As for Russia, the scientific legacy of the scientists raised in the Islamic World such as Avicenna, al-Farabi, Abu Bakr al-Razi, Abu Rayhan al-Biruni, Abu al-Qasim al-Zahrawi, Muhammad ibn Musa al-Khwarizmi, al-Battani, al-Kashi, Abd al-Rahman al-Khazini, Nasir al-Din al-Tusi was researched within the scope of a special plan and program. Depending on the relevant studies, al-Jazari and his work drew attention as well. A small portion of the aforementioned Russian studies is known in Türkiye. It is safe to assume that al-Jazari studies in Russia are virtually unknown in Türkiye. The present study primarily aims to contribute to the literature on the scientific legacy of al-Jazari, a Middle Age Islamic scientist best known for his famous work in the mechanical field. More specifically, the present study aims to: 1) to identify the studies on al-Jazari in Russia, and in the former USSR countries, where academic studies are still in Russian after the Soviet Union period, to create a chronological biography and to set forth their compilation; in other words, to create a bibliography which includes Russian studies on al-Jazari; 2) to provide information on the structure and content of the studies in question, to detect the methodological issues encountered in these works, and make solution recommendations to solve these issues; 3) to contribute to continuing and future studies in Türkiye on al-Jazari in terms of source and material index. In conclusion, it should be stated that comparative reading was conducted centered on The Book of Knowledge of Ingenious Mechanical Devices (Kitab fi ma‘rifati’l-hiyal al-handasiyya). It should also be noted that Russian popular internet publications (which are not based on academic research and are created/reproduced for commercial and personal purposes) were excluded from the assessment.

RésuméCet article se propose de reconstruire une partie du livre IV du traité perdu Sur la démonstration de Galien à partir des témoignages transmis par Abū Bakr al-Rāzī dans les Doutes sur Galien, et d'une source encore jamais exploitée, la Solution aux Doutes sur Galien de Abū al-ʿAlāʾ ibn Zuhr. L'hypothèse à laquelle nous sommes parvenue est que, dans le livre IV, Galien revient sur le caractère indécidable de la question de l’éternité du monde, et critique la démonstration donnée (...) par Aristote dans le traité Du Ciel, I. Seul un des arguments d'Aristote, qui occupe le court passage I, 3, 270b12–17, lui semble pouvoir être sauvé, car il est fondé sur des indications empiriques. C'est sur ce passage que se concentre al-Rāzī. Cette reconstruction permet de réduire les contradictions entre les fragments du livre IV transmis par Philopon dans Contre Proclus sur l’éternité du monde et le compte rendu d'al-Rāzī. Enfin, cet article montre que si al-Rāzī porte autant d'intérêt à ce passage chez Galien, ce n'est pas seulement à des fins polémiques, mais afin de servir ses propres objectifs philosophico-théologiques. Les objections d'al-Rāzī montrent qu'il considère que la téléologie galénique est adossée à un arrière-fond éternaliste qui ne lui permet pas de reconnaître la primauté de la théodicée pour la cosmologie comme pour la biologie.
