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.

Within this emanative scheme we encounter some of the basic ideas of Avicenna's religious and political philosophy, including his discussion of the divine attributes, divine providence, the Hereafter, and the ideal, "virtuous" city with its philosopher-prophet as the recipient and conveyer of the revealed law, a human link between the celestial and the terrestrial worlds."--BOOK JACKET.

Avicenna believes that God must be understood in the first place as the Necessary Existent (wâǧib al-wuǧûd). In his various works, he provides different versions of an ingenious argument for the existence of the Necessary Existent—the so-called Proof of the Sincere (burhân al-ṣiddîqîn)—and argues that all the properties that are usually attributed to God can be extracted merely from God's having necessary existence. Considering the centrality of tawḥîd to Islam, the first thing Avicenna tries to extract from God's necessary existence is God's oneness. The aim of the present Element is to provide a detailed discussion of Avicenna's arguments for the existence and unity of God. Through this project, the author hopes to clarify how, for Avicenna, the Islamic concept of monotheism is intertwined with the concept of essential existence.

This volume examines many aspects of the philosophy of Avicenna, the greatest philosopher of the Islamic world.

The systematic comparison of Avicenna’s Ilāhiyyāt of the Šifā' with Aristotle’s Metaphysics, accomplished for the first time in the present volume, provides a detailed account of Avicenna’s reworking of the epistemological profile and contents of the Metaphysics and a comprehensive investigation of this latter’s transmission in pre-Avicennian Greek and Arabic philosophy.

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.

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.
