These inner conflicts darkened Porphyry’s life, and doubtless made some of the motives which were turning his thoughts to suicide, when Plotinus showed him that this was not the true way of detachment. There was no conflict, but complete surrender, and happy abandonment in Iamblicus the Divine (θεῖος) who when he prayed might be lifted ten cubits from the ground--so thought his disciples--and around whose theurgic fingers, dabbling in a magic basin of water, Cupids played and kissed each other. His life, told by the Neo-Platonic biographer, Eunapius, is as full of miracle as the contemporary Life of St. Antony by Athanasius. Iamblicus floats before us a beautiful and marvellously garbed priest, a dweller in the recesses of temples. He frankly gave himself to theurgy, convinced that the Soul needs the aid of every superhuman being--hero, god, demon, angel.[41] He was credulous on principle. It is of first importance, he writes, that the devotee should not let the marvellous character of an occurrence arouse incredulity within him. He needs above all a “science” (ἐπιστήμη) which shall teach him to disbelieve nothing as to the gods.[42] For the divine principle is essentially miraculous, and magic is the open door, yes, and the way up to it, the anagogic path. All this and more besides is set forth in the _De mysteriis_, the chief composition of his school. It was the answer to that doubting letter of Porphyry to Anebo, and contains full proof and exposition of the occult art of moving god or demon. We all have an inborn knowledge (ἔμφυτος γνῶσις)[43] of the gods. But it is not thought or contemplation that unites us to them; it is the power of the theurgic rite or cabalistic word, understood only by the gods. We cannot understand the reason of these acts and their effects.[44]
