Explaining Evil in Late Antiquity

Abstract

The problem of evil was often debated in the Greco-Roman world of late antiquity. Two very influential contributors to this debate were the Christian theologian Augustine and the pagan Platonist Proclus, whose theory of evil reached the Middle Ages through a paraphrase in the Pseudo-Dionysius. Augustine and Proclus were both influenced by, and distanced themselves from, the original theory of evil developed by the pagan Platonist philosopher Plotinus in the third century AD. Plotinus identified the indeterminate background (“matter”) against which the physical world appears as the reason for the existence of physical and moral evil. Here a summary of Plotinus’s theory of evil is given, together with a discussion of the various difficulties and objections that arise, in particular in Proclus’s criticism of it.
