The six books of Proclus, the Platonic successor, on the theology of Plato (vol. 1 of 2)

The work expounds a Neoplatonic theology in which an ineffable first principle emanates successive orders—intellect, soul, natures, and the world—each sustaining series of beings that descend to corporeal existence. It argues that multiplicity issues from unity by similitude and that divine hypostases function as intermediate causes between the first principle and the sensible realm. Additional treatises consider providence, fate, and the subsistence of evil, while a concise set of doctrinal propositions lays out systematic metaphysical demonstrations. The style combines symbolic imagery with geometric and dialectical reasoning to reconcile mystical theism with rigorous philosophical argument.
