The Demiurge — Craftsman of the Cosmos

The Demiourgos of the Timaeus (28a-29a) is the divine craftsman (technitēs) who fashions the visible kosmos by imposing order upon the pre-existing chora (receptacle/space) using the eternal paradeigma (model) of the intelligible Forms. He is not an omnipotent creator ex nihilo but a maker constrained by ananke (necessity) — the recalcitrance of his material. As Plato states, the Demiurge is agathos (good), and 'being free of jealousy, he desired all things to become as like himself as possible' (Timaeus 29e). The resulting kosmos is a living being with a soul (the World Soul), structured according to mathematical harmoniai and the proportions of the Timaeus' geometric cosmology.
