RésuméCet article examine une brève présentation catéchétique de la doctrine médicale galénique des jours critiques composée par le traducteur et penseur duixesiècle Qusṭā ibn Lūqā (m. 912/3) et que l'on a trouvée dans un manuscrit iranien. Tout d'abord, on démontre que cette œuvre a été composée à partir du traité de Galien sur les jours critiques. Ensuite, on la discute section par section, sous forme de commentaire, pour élucider les doctrines médicales proposées par Qusṭā. Enfin, l'œuvre est comparée avec une (...) tentative antérieure, celle d'al-Kindī (m.c. 870), de décrire les jours critiques d'une façon mathématique. On discute les diverses doctrines présentes à l'arrière-plan du traité, comme les diverses approches de la méthode scientifique. L'article se conclut en mettant en contraste la méthode scientifique mathématique eta priorid'al-Kindī avec la méthode empirique eta posterioride Galien et Qusṭā, et il fait des suggestions concernant la chronologie des occurrences de ces doctrines et de ces textes en langue arabe. Une transcription du texte arabe est donnée en appendice. (shrink)

The author examines the question of Galen's affinity with astrology, in view of Galen's extended astrological discussion in the De diebus decretoriis . The critical passages from Galen are examined, and shown to be superficial in understanding. The author performs a lexical sounding of Galen's corpus, using key terms with astrological valences drawn from the Critical Days, and assesses their absence in Galen's other works. He compares Galen's astrology with the astrology of Ptolemy's Tetrabiblos, and evaluates their respective strategies of (...) scientific reasoning. Three types of inference are introduced and applied to Galen's astrology. Finally, he concludes that the empirical side of Galen's science does not depend upon astrological methods or concepts, but that these were introduced for their rhetorical effect in presenting his new medical methodology. It is suggested that continued attention to Galen's astrology has obscured the truly important empirical scientific method that Galen developed. (shrink)

The internal senses are a class of cognitive faculties that were posited to exist between external sense perception and the intellectual soul. The notion of internal senses was developed in the Arabic philosophy of the Middle Ages on the basis of certain ancient philosophical ideas. The classical list of five internal senses was provided by Avicenna: common sense, retentive imagination, compositive imagination, estimative power, and memory. He also localized these faculties in the three ventricles of the brain. According to Avicenna, (...) the function of common sense is to receive and relate the perceptions of the external senses. The retentive imagination stores the forms of these perceptions and the compositive imagination processes these forms. Furthermore, estimative power grasps the “intentions” of the perceived objects, such as hostility or pleasantness, which the external senses do not perceive. The intentions are finally stored in memory. Averroes’ position was critical of Avicenna’s view, and both accounts had a remarkable influence in medieval Latin philosophy. Avicenna’s view dominated throughout the Middle Ages, although it was challenged and modified with help of other authorities. Albert the Great adhered to Avicenna in general outline, but incorporated some of the views of Averroes, John Damascene, and Qusṭ;a ibn Lūqā. Thomas Aquinas followed the same lines, but further modified the view. There were also constantly differing positions concerning whether the brain or the heart is the primary organ of the internal senses. Peter John Olivi and John Duns Scotus presented a novel reading of the estimative function, which gave up the Avicennian notion of intentions as the objects of the estimative faculty. John Buridan reduced the number of internal senses to two: common sense and memory. His view was adopted by some later authors but rejected by others. (shrink)

An infamous Byzantine scholion about Pisistratus and Homer (Anecd. Gr. II 767–768 Bekker) includes the wildly anachronistic comment that Pisistratus tasked seventy-two scholars, including Zenodotus and Aristarchus, with editing the Homeric poems. The scholion is therefore rightly impugned in modern scholarship. It has however been overlooked that a ninth century Arabic version of the scholion exists in a letter by the Syrian scholar Qusṭā ibn Lūqā (d. 912 ad), which omits mention of the seventy-two scholars and Zenodotus and Aristarchus. As (...) the Arabic version is the earliest precisely dated testimonium for the scholion, it allows for a reconsideration of the textual tradition of this legend about the editorial activity of Pisistratus.

The Arabic philosophical fable _Hayy Ibn Yaqzan _is a classic of medieval Islamic philosophy. Ibn Tufayl, the Andalusian philosopher, tells of a child raised by a doe on an equatorial island who grows up to discover the truth about the world and his own place in it, unaided—but also unimpeded—by society, language, or tradition. Hayy’s discoveries about God, nature, and man challenge the values of the culture in which the tale was written as well as those of every contemporary society. (...) Goodman’s commentary places _Hayy Ibn Yaqzan _in its historical and philosophical context. The volume features a new preface and index, and an updated bibliography. “One of the most remarkable books of the Middle Ages.”—_Times Literary Supplement_ “An enchanting and puzzling story.... The book transcends all historical and cultural environments to settle upon the questions of human life that perpetually intrigue men.”—_Middle East__ Journal_ “Goodman has done a service to the modern English reader by providing a readable translation of a philosophically significant allegory.”—_Philosophy East and West_ “Add[s] bright new pieces to an Islamic mosaic whose general shape is already known.”—_American Historical Review_.

Abū al-Ḥajj¿j Yūsuf b. Muḥammad Ibn Ṭumlūs (Alhagiag Bin Thalmus, d. 620/1223) was a philosopher, physician and direct disciple of Ibn Rushd (Averroes, d. 595/1198), who lived and practiced rational sciences in Alzira and Marrakesh, a quarter of a century after the demise of his teacher. Ibn Ṭumlūs was not Ibn Rushd's only student who engaged in work on logic, but one of dozens of disciples, suggesting that the supposed simultaneous death of the latter's philosophy is "grossly exaggerated". As a (...) valuable window into the practice of logic in 13th century al-Andalus and the Maghreb, Ibn Ṭumlūs' Compendium on Logic (Al-Mukhtaṣar fī al-manṭiq) covers all the parts of "the expanded Organon", as it was known since al-F¿r¿bī (d. 339/951). The present volume offers a complete critical Arabic edition of this work, with an English and Arabic introduction, notes and indices. (shrink)
