Showing the ontological importance oferoswithin the philosophical systems inspired by Plato, Dimitrios A. Vasilakis examines the notion oferosin key texts of the Neoplatonic philosophers, Plotinus, Proclus, and the Church Father, Dionysius the Areopagite.Outlining the divergences and convergences between the three brings forward the core idea of love as deficiency in Plotinus and charts how this is transformed into plenitude in Proclus and Dionysius. Does Proclus diverge from Plotinus in his hierarchical scheme oferos? Is the Dionysian hierarchy to be identified with Proclus' classification of love? By analysingTheEnneads, III.5, theCommentary on the First Alcibiadesand theDivine Namesside by side, Vasilakis uses a wealth of modern scholarship, including contemporary Greek literature to explore these questions, tracing a clear historical line between the three seminal late antique thinkers.
