Plotinus Ennead VI.4 & VI.5

Ennead VI.45, originally written as a single treatise, contains Plotinus most general and sustained exposition of the relationship between the intelligible and sensible realms, addressing and coalescing two central issues in Platonism: the nature of the soulbody relationship and the nature of participation. Its main question is, How can soul animate bodies without sharing in their extension? The treatise seems to have had considerable impact: it is much reflected in Porphyrys 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.
