Oneness, Essence, and Self-Identity: A New Interpretation of Avicenna’s Henology

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.
