Proclus (410-85 CE) was an influential Greek Neoplatonist philosopher. Born in Lycia, he moved to Athens for the remainder of his life.
A lawyer by trade, Proclus came to realize that he preferred philosophy so made a study of the classics and beliefs of his time. Plato, Aristotle, the Stoics, mathematics and the ancient mystery cults were all under his purview.
Modern writers often call him the last of the classical Greek philosophers.
Proclus’ synthesis of Platonic and Aristotelian systems culminates in his theory that an overall, divine action coordinates all cosmic elements as the soul returns back to the One from which it originally emanated. This One is unlike the monotheistic God of Jewish, Muslim and Christian faiths, mainly because it is not a being but rather some kind of creative principle.
