The essays in this book provide the principal theoretical foundation for the "henadological" approach to theology in the polytheistic philosophy of religion, while in a wider perspective constituting the first stage in recovering the sense and significance of henology, the discourse concerning unity, in classical metaphysics. Includes the previously published articles "Polytheism and Individuality in the Henadic Manifold" (2005), "The Gods and Being in Proclus" (2008), "The Intelligible Gods in the Platonic Theology of Proclus" (2008), "The Second Intelligible Triad and the Intelligible-Intellective Gods" (2010), and "The Third Intelligible Triad and the Intellective Gods" (2012), as well as two previously unpublished bonus essays.
