This chapter explores the metaphysical foundations and practical dimensions of theurgy within Neoplatonism, in Iamblichus's approach. It examines three key aspects: theurgy's material dimension, the role of erotic forces and divination as divine communication. Unlike Plotinus and Porphyry who maintained scepticism towards ritual aspects, Iamblichus viewed the material world as a living symbol of divine realms, asserting that properly purified matter facilitates communion with the divine. The chapter articulates how theurgy operates through a triune dynamic of cosmic forces: the Paternal Intellect (the One), Eros (divine attraction), and Anteros (reciprocal love). Through these forces, the theurgist participates in divine creative acts, achieving union with the intelligible realm. The discussion further examines divination as an epiphanic experience rather than mere fortune-telling, highlighting how Iamblichus resignified traditional divinatory practices as pathways for direct divine communion. By positioning divination as communication with ever-present divinity through divine inspiration (mania) and the ‘conducting of light’ (photagogia) Iamblichus established theurgy as a comprehensive framework for experiencing the cosmos as a perpetual divine epiphany.
