They were men of their period, and as Christians their intellectual standards did not rise nor their understanding of fact alter, although their approvals and disapprovals might be changed. Their natures might be stimulated and uplifted by the Faith and its polemic ardours, and yet their manner of approaching and apprehending facts, its facts, for example, might continue substantially those of their pagan contemporaries or predecessors.
In the fourth century the leaders of the Church both in the East and West were greater men than contemporary pagan priests or philosophers or rhetoricians. For the strongest minds had enlisted on the Christian side, and a great cause inspired their highest energies with an efficient purpose.

It has appeared that metaphysical interests absorbed the attention of Plotinus, who has nevertheless his supreme irrationality atop of all. Porphyry also possessed a strong reasoning nature, but was drawn irresistibly to all the things, gods, demons, divination and theurgy, of which one half of him disapproved.
