Whether or not Iamblichus wrote the famous work usually attributed to him, which describes itself as the letter of Abamnon the Teacher to Porphyry, he became the head of that school of Neoplatonists who fell back on theurgy and magic, and utterly swallowed up the more rational, though more hopeless, school of Porphyry. Not that Porphyry, too, with all his dislike of magic and the vulgar superstitions—a dislike intimately connected with his loudly expressed dislike of the common herd, and therefore of Christianity, as a religion for the common herd—did not believe a fact or two, which looks to us, nowadays, somewhat unphilosophical. From him we learn that one Ammonius, trying to crush Plotinus by magic arts, had his weapons so completely turned against himself, that all his limbs were contracted. From him we learn that Plotinus, having summoned in the temple of Isis his familiar spirit, a god, and not a mere dæmon, appeared. He writes sensibly enough however to one Anebos, an Egyptian priest, stating his doubts as to the popular notions of the Gods, as beings subject to human passions and vices, and of theurgy and magic, as material means of compelling them to appear, or alluring them to favour man. The answer of Abamnon, Anebos, Iamblichus, or whoever the real author may have been, is worthy of perusal by every metaphysical student, as a curious phase of thought, not confined to that time, but rife, under some shape or other, in every age of the world’s history, and in this as much as in any. There are many passages full of eloquence, many more full of true and noble thought: but on the whole, it is the sewing of new cloth into an old garment; the attempt to suit the old superstition to the new one, by eclectically picking and choosing, and special pleading, on both sides; but the rent is only made worse. There is no base superstition which Abamnon does not unconsciously justify. And yet he is rapidly losing sight of the real eternal human germs of truth round which those superstitions clustered, and is really further from truth and reason than old Homer or Hesiod, because further from the simple, universal, everyday facts, and relations, and duties of man, which are, after all, among the most mysterious, and also among the most sacred objects which man can contemplate.
