DIAGRAM OF THE UNIVERSE.
Project Gutenberg EPUB3 edition
Plotinus and Guthrie, Kenneth Sylvan
The Soul, such as we are considering her here, is something venerable; she resembles a circle which is united to the centre, and which develops without leaving (its base of operations, the centre), thus forming an undivided extension. To gain a conception of the order of the three principles, the Good may be considered as a centre, the Intelligence as an immovable circle, and the Soul as an external movable circle impelled by desire.
