may infer what kind of gods these are, and what kind of vision of them is imparted by theurgic consecrations, if by it one cannot see the things which truly exist. He says, further, that the rational, or, as he prefers calling it, the intellectual soul, can pass into the heavens without the spiritual part being cleansed by theurgic art, and that this art cannot so purify the spiritual part as to give it entrance to immortality and eternity. And therefore, although he distinguishes angels from demons, asserting that the habitation of the latter is in the air, while the former dwell in the ether and empyrean, and although he advises us to cultivate the friendship of some demon, who may be able after our death to assist us, and elevate us at least a little above the earth,–for he owns that it is by another way we must reach the heavenly society of the angels,–he at the same time distinctly warns us to avoid the society of demons, saying that the soul, expiating its sin after death, execrates the worship of demons by whom it was entangled. And of theurgy itself, though he recommends it as reconciling angels and demons, he cannot deny that it treats with powers which either themselves envy the soul its purity, or serve the arts of those who do envy it. He complains of this through the mouth of some Chaldaean or other: “A good man in Chaldaea complains,” he says, “that his most strenuous efforts to cleanse his soul were frustrated, because another man, who had influence in these matters, and who envied him purity, had prayed to the powers, and bound them by his conjuring not to listen to his request. Therefore,” adds Porphyry, “what the one man bound, the other could not loose.” And from this he concludes that theurgy is a craft which accomplishes not only good but evil among gods and men; and that the gods also have passions, and are perturbed and agitated by the emotions which Apuleius attributed to demons and men, but from which he preserved the gods by that sublimity of residence, which, in common with Plato, he accorded to them.
