Plotinus and His Critics
from Part II - Ethics
Published online by Cambridge University Press: 08 December 2025
Plotinus provided an explanation of evil which was original and philosophically challenging. While deriving everything from one source, the absolute transcendent Good, Plotinus does not trivialize the phenomenon of evil or reduce it to human moral deviation, as do other philosophical and religious approaches, but traces evil back to a metaphysical principle, matter, the source of evil in the world and in human souls. In Chapter 11 I present Plotinus’ account of evil and discuss to what extent it can be defended against a series of criticisms formulated by Plotinus’ successors, in particular by Proclus.
