Abstract
Clearly a Late Antiquity’s phenomenon, the Neoplatonism represented to the ancient men the last bastion of its old traditions, the religion of their ancestors and classical culture. Especially the neoplatonic philosophy of Plotinus, that had engendred precepts which, by its meanings, resounded through the last voices of paganism and survived the Middle Ages into the scholastic philosopy. Although the ideas of Plotinus achieved such later importance, it were the main problem conceiving the conflicts between the philosophers Porphyry and Iamblichus. That will be the starting point of this paper, which analyzes the layers of Neoplatonism throught its historical context.
