But it is said Providence, from above, from what is of prime importance, as from the head, reaches to all, “as the ointment,” it is said, “which descends to Aaron’s beard, and to the skirt of his garment”[1168] (that is, of the great High Priest, “by whom all things were made, and without whom not even one thing was made”[1169]); not to the ornament of the body; for Philosophy is outside of the People, like raiment.[1170] The philosophers, therefore, who, trained to their own peculiar power of perception by the spirit of perception, when they investigate, not a part of philosophy, but philosophy absolutely, testify to the truth in a truth-loving and humble spirit; if in the case of good things said by those even who are of different sentiments they advance to understanding, through the divine administration, and the ineffable Goodness, which always, as far as possible, leads the nature of existences to that which is better. Then, by cultivating the acquaintance not of Greeks alone, but also of Barbarians, from the exercise common to their proper intelligence, they are conducted to Faith. And when they have embraced the foundation of truth, they receive in addition the power of advancing further to investigation. And thence they love to be learners, and aspiring after knowledge, haste to salvation. Thus Scripture says, that “the spirit of perception” was given to the artificers from God.[1171] And this is nothing else than Understanding, a faculty of the soul, capable of studying existences,--of distinguishing and comparing what succeeds as like and unlike,--of enjoining and forbidding, and of conjecturing the future. And it extends not to the arts alone, but even to philosophy itself. Why, then, is the serpent called wise? Because even in its wiles there may be found a connection, and distinction, and combination, and conjecturing of the future. And so very many crimes are concealed; because the wicked arrange for themselves so as by all means to escape punishment.
