Works

Position

Proclus was the great systematiser of late Neoplatonism. In his Elements of Theology he derives the whole of reality from the One in 211 propositions, in a deductive form modelled on Euclid. Each level unfolds in a triad of remaining, procession and return: every effect remains in its cause, proceeds from it and turns back to it. Between the One and the world he places a richly articulated hierarchy of henads, intellects and souls. He also wrote extensive commentaries on Plato and Euclid. Through the Christian writer known as Pseudo-Dionysius and the Arabic Book of Causes, his thought deeply influenced medieval theology.

Life & context

Proclus was born in Constantinople, grew up in Lycia and studied in Alexandria before moving to Athens, where he became head of the Platonic school and led it for nearly fifty years. Deeply religious, he practised the old pagan rites in an increasingly Christian empire. His life was described by his pupil and successor Marinus.
