Abstract
In his reflection on the nature of evil, the Neoplatonic philosopher Proclus affirms that evil itself is “also beyond the absolute non-being”. With this assumption, he intends to reinforce the thesis of the non-existence of absolute evil, conceived as totally separate from good, and contrasted with the collateral and parasitic existence of evil mixed with good. He thus maintains a distinction between absolute evil and relative evil, conceived with reference to the distinction between absolute non-being and relative non-being. In Proclus, the thesis of the non-existence of absolute evil is presented as a necessary consequence of the non-dualist theory of evil in the sphere of a protology that identifies the first Principle of all things in the primary Good, and which aims to reconcile the absolute primacy of the latter with the presence of evil in some orders of reality.
