In how many ways can things be said to be one, how is oneness itself to be defined, and what is its relation to essence and existence? This book engages with these core questions by examining the works of Avicenna (d. 1037 CE), who is widely regarded as the most important philosopher of the Arabic tradition. In this monograph - the first that is exclusively devoted to Avicenna's henology and to Arabic henology in general - the author analyzes the place and meaning of oneness in Avicenna's general metaphysics and theology and devotes particular attention to how this notion relates to Avicenna's theory of quiddity. He contextualizes Avicenna's doctrines in light of three major intellectual currents (ancient Greek philosophy, early Arabic philosophy, and Islamic theology or kalām) and also offers the first detailed analysis of oneness in the Bahshamite tradition. The book challenges the prevailing interpretation of Avicenna's henology and adduces new textual evidence to show that Avicenna developed an innovative theory of oneness that expresses the essential reality and self-identity of a thing. This foundational sense of oneness is applied to all the pure quiddities and, in an eminent and prior way, to God.

This study focuses on the metaphysics of the great Arabic philosopher Avicenna (or Ibn Sina, 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 (kalam). 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.
