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 Chaldæan or other: "A good man in Chaldæa 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.
- Concerning theurgy, which promises a delusive purification of the soul by the invocation of demons.
But here we have another and a much more learned Platonist than Apuleius, Porphyry, to wit, asserting that, by I know not what theurgy, even the gods themselves are subjected to passions and perturbations; for by adjurations they were so bound and terrified that they could not confer purity of soul,—were so terrified by him who imposed on them a wicked command, that they could not by the same theurgy be freed from that terror, and fulfil the righteous behest of him who prayed to them, or
