Abstract
Devoted to the key Neoplatonic concepts of procession and emanation. The two terms are taken to express the same idea, although procession is preferred as more neutral. Points out how procession can be explained in Aristotelian terms. More specifically, it is demonstrated how Plotinus’ notion of procession uses the Aristotelian theory of the actualization of an activity by a potency in order to explain how a higher activity can actualize a lower one. Finally, considers the doctrine of Proclus who expresses the procession, involving the theory of causal relation, in a way opposite to Plotinus.
