Additional source material: _Select Works of Plotinus_, translated by Thomas Taylor, ed. G. R. S. Mead, London, 1909 (contains bibliography of other translations of Plotinus, including those in French and German together with a select list of works bearing on Neo-Platonism); _Select Works of Porphyry_, trans. by Thomas Taylor, London, 1823; Taylor translated much from all the Neo-Platonists, but his other books are very scarce. Porphyry’s _Epistula ad Marcellam_, trans. by Alice Zimmern, London, 1896. Porphyry, _Ep. ad Marcellam_, 16-19. _Porphyrii philosophi Platonici opuscula tria_, rec. A. Nauck, Leipsic, 1860. The letter is addressed to Marcella by her husband, the philosopher Porphyry. It gives a good idea of the religious and ethical character of Neo-Platonism. For the metaphysical aspects see Plotinus, translated by T. Taylor. Porphyry was, after Plotinus, the greatest of the Neo-Platonists, and brought out most clearly those religious elements which were rivals to Christianity. His attack upon Christianity was keen and bitter, and he was consequently especially hated by the Christians. He died at Rome 304. Ch. 16. You will honor God best when you form your soul to resemble him. This likeness is only by virtue; for only virtue draws the soul upward toward its own kind. There is nothing greater with God than virtue; but God is greater than virtue. But God strengthens him who does what is good; but of evil deeds a wicked demon is the instigator. Therefore the wicked soul flees from God and wishes that the foreknowledge of God did not exist; and from the divine law which punishes all wickedness it shrinks away completely. But a wise man’s soul is in harmony with God, ever sees Him, ever is with Him. But if that which rules takes pleasure in that which is ruled, then God cares for the wise and provides for him; and therefore is the wise man blessed, because he is under the protection of God. It is not the discourses of the wise man which are honorable before God, but his works; for the wise man, even when he keeps silence, honors God, but the ignorant man, even in praying and sacrificing, dishonors the Divinity. So the wise man alone is a priest, alone is dear to God, alone knows how to pray.
