What role does Soul play in forming and ordering the material universe?

In the philosophy of Plotinus, the Soul serves as the vital intermediary between the world of Intellect and the physical realm. Produced by Intellect, the Soul is responsible for forming, ordering, and maintaining the material universe in existence.1

The Soul performs this role through two primary phases:

• Ruling from above: The Soul acts as a governing principle, where its movement—which constitutes time—serves as the foundation for all physical movement.1
• Immanent activity: In its lower phase, often referred to as nature, the Soul acts as an indwelling force of life and growth, producing the structures of bodies.1

Plotinus viewed the material universe as a living, organic whole—the best possible reflection of the intelligible world. It is held together by a universal harmony and sympathy, with the Soul acting as the World-Soul that ensures the cosmos remains a unified, ordered entity. While the Soul interacts with the darkness of matter, it ultimately bestows beauty and goodness upon the physical world.12
