The present work deals with establishing of the exact meaning of the technical terms used by al-Kindi in the longest of his extant philosophical treatises, The Letter on the First Philosophy. On many occasions, however, when the meaning of a term appeared to be obscure in the Letter, the evidence of al-Kindī's usage of such a term has had to be brought forward from his other philosophical works in order to elucidate its meaning as accurately as possible.

Al-Kindi was the first philosopher of the Islamic world. He lived in Iraq and studied in Baghdad, where he became attached to the caliphal court. In due course he would become an important figure at court: a tutor to the caliph's son, and a central figure in the translation movement of the ninth century, which rendered much of Greek philosophy, science, and medicine into Arabic. Al-Kindi's wide-ranging intellectual interests included not only philosophy but also music, astronomy, mathematics, and medicine. Through (...) deep engagement with Greek tradition al-Kindi developed original theories on key issues in the philosophy of religion, metaphysics, physical science, and ethics. He is especially known for his arguments against the world's eternity, and his innovative use of Greek ideas to explore the idea of God's unity and transcendence. Despite al-Kindi's historical and philosophical importance no book has presented a complete, in-depth look at his thought until now. In this accessible introduction to al-Kindi's works, Peter Adamson surveys what is known of his life and examines his method and his attitude towards the Greek tradition, as well as his subtle relationship with the Muslim intellectual culture of his day. Above all the book focuses on explaining and evaluating the ideas found in al-Kindi's wide-ranging philosophical corpus, including works devoted to science and mathematics. Throughout, Adamson writes in language that is both serious and engaging, academic and approachable. This book will be of interest to experts in the field, but it requires no knowledge of Greek or Arabic, and is also aimed at non-experts who are simply interested in one of the greatest of Islamic philosophers.

"The world is a finite body, and therefore has finite power." John Philoponus is remembered for using this Aristotelian premise to break ranks with Aristotle and argue that the world is not everlasting. This investigation reconsiders Philoponus’s arguments from finite power, and then explores the aftermath of this line of thinking in the works of three lesser-known Arabic intellectuals active in the generation before Avicenna (d. 1037): Abū l-Ḫayr Ibn Suwār (d. after 1017), Abū al-Ḥasan al-ʿĀmirī (d. 992), and Abū (...) Sahl al-Masīḥī (d. after 1025). Each engaged with this dictum in unique and novel ways, and in so doing anticipated a number of central features of Avicenna’s writings. The history of this argument is of crucial importance for understanding the evolution of natural philosophy and metaphysics in this formative period, away from tedious and simplistic arguments about creation and towards a more robust modal ontology based on intrinsic and extrinsic necessity.

SummaryChristian theologians can explain the Trinitarian faith today in dialogue with Islamic thinkers as “deepened monotheism”. Therefore it is important to widen the systematic-theological discourse in an ecumenical and transcultural perspective and to retrieve resources from Western and non-Western traditions of Trinitarian thought (I).In this paper I will first work out historically that the Trinitarian creed of Nicea and Constantinople was originally an ecumenical but non-Western creed (II). Afterwards, I investigate the philosophical-theological reflection on the Trinity by Anselm of Canterbury (...) (1033–1109) in the context of early interreligious encounters in the Latin West. Based on biblical, augustinian and Greek sources, he developed an approach to understand the mystery of the Trinity by rational arguments as “deepened monotheism” (III). Then I will proceed to explore the philosophical-theological dialogues on the Trinity from the Arabic philosopher and Syrian-orthodox theologian Yaḥyā ibn ‘Adī (893–974). Much earlier he developed rational arguments for the Triunity of God with reference to Aristotle. Thereby he answers to anti-trinitarian arguments from Islamic thinkers like al-Kindī and al-Warrāq. He intends that the Trinitarian faith of Christian minorities can thereby be understood and tolerated by Islamic thinkers as rationally founded “deepened monotheism” (IV).In the end I will evaluate what these classics from the Western and non-western traditions of Trinitarian thought contribute to explicate the doctrine of the Trinity today in a pluralistic religious context as “deepened monotheism” (V).

RésuméLa tradition manuscrite duKitāb al-Kašf, conserve la trace matérielle de trois phases de rédaction et de révision de l'ouvrage. Cette étude vise à expliciter les relations entre les deux versions arabes et la traduction hébraïque anonyme du XIVesiècle, en prenant en compte les additions et remaniements qui les différencient. Je conclus que la traduction hébraïque représente un stade intermédiaire de réélaboration: elle atteste d'importants ajouts et modifications philosophiques, spécialement dans les arguments portant sur la création du monde, au début de (...) l'ouvrage, mais précède l'achèvement de la révision du traité, qui a conduit aux remaniements dont témoigne la dernière version arabe, dans les chapitres abordant les questions épineuses de la corporéité divine et de la direction. L'étude des ajouts et des arguments du point de vue du contenu, du contexte et de l'argumentation contribue également à comprendre l'histoire de la stratification des phases rédactionnelles de l'ouvrage et la manière dont l'ouvrage a été transmis.

Dans cet article, l'auteur fait état de nouvelles données à propos de trois traités attribués a Alexandre d'Aphrodise en arabe et dont on pensait qu'ils n'avaient pas de correspondant grec. II montre que le premier (D.8a) est une version adaptée – selon les normes du “cercle d'al-Kindi’ – deQuaestioI 21, à côte de la traduction plus tardive et plus exacte de cette mêmeQuaestiodue à Abù ‘Uṭmān al-Dimašqī (m. 900). II montre que les deux autres traités (D.9 et D.16), en revanche, (...) ne sont pas d'Alexandre d'Aphrodise, mais qu'il s'agit de versions adaptées – toujours selon les normes du “cercle d'al-Kindi” – de passages duDe Aeternitate mundi contra Proclumde Jean Philopon, empruntés respectivement à IV, 4–6 et IX, 11. On savait que cet ouvrage fut traduit en arabe. Mais, hormis quelques courts fragments dans al-Bīrūnī (m. 1048), c'est, semble-t-il, la première fois que l'on en met au jour des extraits adaptés de cette importance. Des jalons sont posés en vue de répondre à la question de la situation historique de l'epitomateur. Dans l'Appendice II, un autre traité attribué à Alexandre (D.27g) apparaît – provisoirement – comme un texte composite mêlant des éléments issus de Philopon et d'autres issus des textes néoplatoniciens en arabe. Enfin dans l'Appendice III, sont situées la manière dont Miskawayh (m. 1030) utilise D.16, et celle dont ‘Abdallaṭīf al-Baġdādī (m. 1231) utilise D.27g. (shrink)

Al-Kindī's views concerning time are dispersed in different places in his works, but they are to be found principally in his On First Philosophy and De quinque essentiis. Yes, he does follow Aristotle, but he insists on the homogeneity of the instant and of time; he also distances himself from the Philosopher by denying the eternity of the world a parte ante as well as a parte post. On the other hand, in his accounts of the realization of possible things (...) and of the organization of the cosmos, he presents certain views that sometimes tend toward the principle of plenitude, and sometimes toward the doctrine of the best possible world, and here one can discern a principle that is distinctly theological.

This article offers an analysis, translation, and edition of a brief, recently uncovered Arabic text by the tenth-century CE Christian Aristotelian thinker Yaḥyā ibn ʿAdī. Ibn ʿAdī here takes issue with an argument for the existence of God, widely used in kalām. According to this argument, bodies cannot exist without being either in motion or at rest; motion and rest must begin; therefore all bodies and hence the universe as a whole must have begun. Ibn ʿAdī diagnoses various flaws in (...) this reasoning, including a supposed part–whole fallacy. The analysis of the text shows how it fits into Ibn ʿAdī’s intellectual profile and the project of the Baghdad Aristotelian school. (shrink)

This volume examines the phenomenon of the migration of philosophical texts and traditions into other cultures, identifies places where it may have succeeded, but also where it has not, and discusses what is presupposed in introducing a text or a tradition into another intellectual culture. -- Book Jacket.
