The Platonists of the Alexandrian and Athenian schools, from Plotinus to Proclus, are at one in recognizing in God three principles or hypostases: 1st, the One or the Good, which is the Father; 2nd, the Intelligence or Word, which is the Son; 3rd, the Soul, which is the universal principle of life. But as to the nature and order of these hypostases, the Alexandrians are no longer at one with the school of Athens. On the very subtle differences between the Trinity of Plotinus and that of Porphyry, consult M. Jules Simon, ii. 110, and M. Vacherot, ii. 37.—Saisset.
