This study focuses on the metaphysics of the great Arabic philosopher Avicenna (or Ibn Sīnā, d. 1037 C.E.). More specifically, it delves into Avicenna’s theory of quiddity or essence, a topic which seized the attention of thinkers both during the medieval and modern periods. Building on recent contributions in Avicennian studies, this book proposes a new and comprehensive interpretation of Avicenna’s theory of ‘the pure quiddity’ (also known as ‘the quiddity in itself’) and of its ontology. The study provides a careful philological analysis of key passages gleaned from the primary sources in Arabic and a close philosophical contextualization of Avicenna’s doctrines in light of the legacy of ancient Greek philosophy in Islam and the early development of Arabic philosophy (falsafah) and theology (kalām). The study pays particular attention to how Avicenna’s theory of quiddity relates to the ancient Greek philosophical discussion about the universals or common things and Mu’tazilite ontology. Its main thesis is that Avicenna articulated a sophisticated doctrine of the ontology of essence in light of Greek and Bahshamite sources, which decisively shaped subsequent intellectual history in Islam and the Latin West.

Philosophical Theology in Islam studies the later history of the Ashʿarī school of theology through in-depth probings of its thought, sources, scholarly networks and contexts. Starting with a review of al-Ghazālī’s role in the emergence of post-Avicennan philosophical theology, the book offers a series of case studies on hitherto unstudied texts by the towering thinker Fakhr al-Dīn al-Rāzī as well as specific philosophical and theological topics treated in his works. Studies furthermore shed light on the transmission and reception of later Ashʿarī doctrines in periods and regions that have so far received little scholarly attention. This book is the first exploration of the later Ashʿarī tradition across the medieval and early-modern period through a trans-regional perspective. Contributors: Peter Adamson, Asad Q.

In Necessary Existence and the Doctrine of Being in Avicenna’s Metaphysics of the Healing Daniel De Haan examines the primary notions being, thing, one, and necessary and their roles in the central argument of Avicenna’s metaphysical masterpiece.

The eleventh-century philosopher and physician Abu Ali ibn Sina (d. A.D. 1037) was known in the West by his Latinized name Avicenna. An analysis of the sources and evolution of Avicenna's metaphysics, this book focuses on the answers he and his predecessors gave to two fundamental pairs of questions: what is the soul and how does it cause the body; and what is God and how does He cause the world? To respond to these challenges, Avicenna invented new concepts and distinctions and reinterpreted old ones. The author concludes that Avicenna's innovations are a turning point in the history of metaphysics. Avicenna's metaphysics is the culmination of a period of synthesis during which philosophers fused together a Neoplatonic project (reconciling Plato with Aristotle) with a Peripatetic project (reconciling Aristotle with himself). Avicenna also stands at the beginning of a period during which philosophers sought to integrate the Arabic version of the earlier synthesis with Islamic doctrinal theology (kalam). Avicenna's metaphysics significantly influenced European scholastic thought, but it had an even more profound impact on Islamic intellectual history—the philosophical problems and opportunities associated with the Avicennian synthesis continued to be debated up to the end of the nineteenth century.

This work focuses on the intellectual and educational history of Baghdad in the early ʿAbbāsid and Bāyid periods (8th-10th centuries). It covers a wide range of disciplines taught in the metropolis before the institutionalization of the madrasa system. Among these fields of knowledge are Arabic poetry and literature, the transmission of prophetic reports, Arabic historiography and astronomical-astrological teaching. Christian learning in the city is highlighted by two contributions, while two more papers focus on Jewish practices of knowledge production. The volume seeks to promote a better understanding of Baghdad's multi-cultural circles of learning, the transmission of knowledge, and common patterns of patronage during this period.
