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 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

RésuméCet article propose une analyse et une traduction d'un ouvrage de Miskawayh déjà édité mais non étudié par ailleurs, et intitulé Des plaisirs et des douleurs. Après une étude préliminaire concernant la doctrine aristotélicienne du plaisir dans l‘Éthique à Nicomaque, qui est la principale source de Miskawayh, la doctrine du plaisir présentée dans le traité Des plaisirs et des douleurs est comparée à la discussion du plaisir dans l'ouvrage mieux connu de Miskawayh La réforme des mœurs. En dépit de l'harmonie globale qu'il y a entre les deux œuvres, leur traitement du plaisir diffère en ce que La réforme accepte la conception du plaisir comme restauration issue du Timée de Platon, alors que le traité Des plaisirs et des douleurs la rejette.

L'analisi dell'aristotelismo «platonizzante» nell'ambito della filosofia araba prima della sistemazione della Shifa di Avicenna, secondo cui Dio non avrebbe conoscenza dei particolari, consente all'A. di dimostrare come ci siano stati anche approcci platonici ad Aristotele , che non sono passati attraverso il filtro dei neoplatonici greci. L'altra cosa significativa è il fatto che all'interno della scuola di Baghdad vi sono modi diversi di intendere lo stato ontologico degli universali. L'A. tenta anche di ridimensionare la figura di al-Farabi all'interno della scuola di Baghdad. I filosofi considerati sono al-Farabi, Yahya b. Adi e Ibn al-Tayyib

Ancient commentators like Ammonius and Boethius tried to solve Aristotle's “sea battle argument” in On Interpretation 9 by saying that statements about future contingents are “indefinitely” true or false. They were followed by al-Fārābī in his commentary on On Interpretation. The article sets out two possible interpretations of what “indefinitely” means here, and shows that al-Fārābī actually has both conceptions: one applied in his interpretation of Aristotle, and another that he is forced into by the problem of divine foreknowledge. It also explains the relevance of al-Fārābī's remarks as a link between the non-statistical modal theories of Philo and Avicenna

The paper discusses al-Kindī's response to doctrines held by contemporary theologians of the Mu‘tazilite school: divine attributes, creation, and freedom. In the first section it is argued that, despite his broadly negative theology, al-Kindī recognizes a special kind of “essential” positive attribute belonging to God. The second section argues that al-Kindī agreed with the Mu‘tazila in holding that something may not yet exist but still be an object of God's knowledge and power. Also it presents a new parallel between al-Kindī and John Philoponus. The third section gives an interpretation of al-Kindī as a compatibilist, in other words as holding that humans may be free even though their actions are necessitated. In all three cases, it is argued, al-Kindī is close to the Mu‘tazilite point of view, though he departs from them in the arguments he gives for that point of view.

Peter Adamson presents the first full history of philosophy in the Islamic world for a broad readership. He traces its development from early Islam to the 20th century, ranging from Spain to South Asia, featuring Jewish and Christian thinkers as well as Muslim. Major figures like Avicenna, Averroes, and Maimonides are covered in great detail, but the book also looks at less familiar thinkers, including women philosophers. Attention is also given to the philosophical relevance of Islamic theology and mysticism--the Sufi tradition within Islam, and Kabbalah among Jews--and to science, with chapters on disciplines like optics and astronomy. The first part of the book looks at the blossoming of Islamic theology and responses to the Greek philosophical tradition in the world of Arabic learning, the second discusses philosophy in Muslim Spain, and a third section looks in unusual detail at later developments, touching on philosophy in the Ottoman, Mughal, and Safavid empires.

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.
