Ennead VI.4 and VI.5 ─ On the Presence of Being, One and the Same, Everywhere As a Whole

Ennead VI.4-5, originally written as a single treatise, contains Plotinus' most general and sustained exposition of the relationship between the intelligible and the sensible realms, addressing and coalescing two central issues in Platonism: the nature of the soul-body relationship and the nature of participation. Its main question is, How can soul animate bodies without sharing their extension? The treatise seems to have had considerable impact: it is much reflected in Porphyry's important work,Sententiae, and the doctrine of reception according to the capacity of the recipient, for which this treatise is the main source, resonated in medieval thinkers.
