This chapter provides an overview of the evidence regarding al-Kindī’s biography, and surveys what is known of his writings based on the account in Ibn al-Nadīm’s Fihrist. While most of his works are lost, there is a significant extant corpus which is also summarized here. The chapter discusses how al-Kindī’s writings relate to the translation movement under the ’Abbāsids, which produced Arabic versions of Greek philosophical and scientific works. It concludes by considering al-Kindī’s legacy, among Neoplatonic philosophers who followed his broad approach, contrasting this “Kindian tradition” to the more Aristotelian school in Baghdad, whose most famous representative was al-Fārābī.

This chapter discusses al-Kindī’s main influences from Greek works produced by the translation movement, and how al-Kindī thought the ideas from these works should be put together into a coherent philosophical curriculum. In philosophy, al-Kindī was most influenced by Aristotle and by Neoplatonic works. His vision of philosophical methodology follows a Greek tradition of dividing philosophy up in terms of the different objects studied in different sciences. Finally, the chapter discusses the role of the Arabic language and Islam in al-Kindī’s thought by surveying texts in which he engages in Koranic exegesis, and by explaining his project of developing a new Arabic terminology in philosophy.

Al-Kindī’s extant ethical corpus is relatively small, but sufficient to show that his ethics is an application of his Neoplatonic ideas about metaphysics and psychology. He provides the first Arabic account of Socrates, a philosophical hero who is presented as despising things of the physical world, or “external goods” — Socrates is here conflated with the Cynic philosopher Diogenes. In al-Kindī’s largest ethical treatise, On Dispelling Sorrows, al-Kindī provides a work of consolation which uses Platonist ideas to undergird a broadly Stoic or Cynic teaching on the value of external goods.

In late antiquity, the commentary became the most prominent genre of philosophical writing. Aristotle was the author who received the lion's share of attention, even though the commentators, beginning with Porphyry, were Platonists. Since Aristotle was seen not only as harmonious with Plato, but as more suitable for initial study in philosophy, commentaries for the use of students were naturally more often devoted to his works than to Plato's. The practice of writing commentaries on Aristotle, and the curriculum the commentaries were meant to support, cut across confessional lines. The Arabic tradition of commentary on Aristotle focuses on the earlier parts of the Aristotelian curriculum, with most emphasis on the logical and physical works. Only the greatest commentator of the Arabic tradition, Averroes, commented extensively on the De Anima or the Metaphysics. As in the Greek tradition, confessional divides were no obstacle to continuous and even co-ordinated efforts to understand Aristotle. This is best shown by the group of commentators known as the “Baghdad school.”

Al-Kindi was influenced by two Greek traditions in his attempts to explain vision, light and color. Most obviously, his works on optics are indebted to Euclid and, perhaps indirectly, to Ptolemy. But he also knew some works from the Aristotelian tradition that touch on the nature of color and vision. Al-Kindi explicitly rejects the Aristotelian account of vision in his De Aspectibus, and adopts a theory according to which we see by means of a visual ray emitted from the eye. But in the same work, al-Kindi draws on Philoponus.

Philosophy written in Arabic and in the Islamic world represents one of the great traditions of Western philosophy. Inspired by Greek philosophical works and the indigenous ideas of Islamic theology, Arabic philosophers from the ninth century onwards put forward ideas of great philosophical and historical importance. This collection of essays, by some of the leading scholars in Arabic philosophy, provides an introduction to the field by way of chapters devoted to individual thinkers or groups, especially during the 'classical' period from the ninth to the twelfth centuries. It also includes chapters on areas of philosophical inquiry across the tradition, such as ethics and metaphysics. Finally, it includes chapters on later Islamic thought, and on the connections between Arabic philosophy and Greek, Jewish, and Latin philosophy. The volume also includes a useful bibliography and a chronology of the most important Arabic thinkers.

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

L'A. confronta due commenti su quello che nel mondo arabo viene considerato il primo libro della Metaphysica di Aristotele: alpha Elatton. Dopo averne delineato i contenuti e la penetrazione nel mondo arabo grazie alle traduzioni di Ustat e Ishaq ibn Hunayn, l'A. esamina due importanti commenti a quest'opera: Yahyá Ibn 'Adi, un commentatore cristiano della scuola di Baghdad e Averroè . I due autori leggono il testo in modo molto diverso: questo suggerisce una grande differenza tra Averroè e la scuola di Baghdad, sebbene il filosofo andaluso abbia ammirato e seguito il lavoro di al-Farabi. In particolare è naturale il rifiuto da parte di Averroè di introdurre un'inchiesta puramente teologica nella trattazione, punto accettato invece da Ibn 'Adi, secondo il proposito di Averroè di rimarcare il fondamento fisico della metafisica, come è possibile comprendere soprattutto grazie alla lettura del Trattato

Avicenna is the greatest philosopher of the Islamic world. His immense impact on Christian and Jewish medieval thought, as well as on the subsequent Islamic tradition, is charted in this volume alongside studies which provide a comprehensive introduction to and analysis of his philosophy. Contributions from leading scholars address a wide range of topics including Avicenna's life and works, conception of philosophy and achievement in logic and medicine. His ideas in the main areas of philosophy, such as epistemology, philosophy of religion and physics, are also analyzed. While serving as a general introduction to Avicenna's thought, this collection of critical essays also represents the cutting edge of scholarship on this most influential philosopher of the medieval era.

This paper studies the first metaphysical theory in Arabic philosophy, that of al-Kindi, as found in "On First Philosophy" and other of his works. Placing these works against the background of translations produced in al-Kindi's circle (the "Theology of Aristotle," which is the Arabic version of Plotinus, and the "Liber de Causis," the Arabic version of Proclus' "Elements of Theology"), it argues that al-Kindi has two conceptions of being: "simple" being, which excludes predication and derives from Neoplatonism, and "complex" being, which is based on Aristotle's notion of substance. At the end of the paper the "simple" notion of being is seen to anticipate in some respects Avicenna's distinction between existence and essence

Peter Adamson offers an accessible, humorous tour through a period of eight hundred years when some of the most influential of all schools of thought were formed. He introduces us to Cynics and Skeptics, Epicureans and Stoics, emperors and slaves, and traces the development of early Christian philosophy and of ancient science. A major theme of the book is in fact the competition between pagan and Christian philosophy in this period, and the Jewish tradition appears in the shape of Philo of Alexandria. Ancient science is also considered, with chapters on ancient medicine and the interaction between philosophy and astronomy. Considerable attention is paid also to the wider historical context, for instance by looking at the ascetic movement in Christianity and how it drew on ideas from Hellenic philosophy. From the counter-cultural witticisms of Diogenes the Cynic to the subtle skepticism of Sextus Empiricus, from the irreverent atheism of the Epicureans to the ambitious metaphysical speculation of Neoplatonism, from the ethical teachings of Marcus Aurelius to the political philosophy of Augustine, the book gathers together all aspects of later ancient thought in an accessible and entertaining way.
