The Elements Of Theology by Proclus

A concise Neoplatonic exposition arranged as numbered propositions and proofs, it outlines a hierarchical cosmos emanating from the ineffable One through henads, intelligible and intellective orders, to soul and nature. It develops the triad of remaining, procession, and reversion, explains participation and the causal dependence of lower on higher, and shows how unity grounds multiplicity. The work culminates in the soul’s philosophical re-ascent toward its source, offering a rigorous map of metaphysical principles and the structure of being.
