In this we have the main ideas on which the intellectualism of Plotinus is based, the general conceptions to which everything particular is led back; the instances in which this is done are often, however, figurative. What, in the first place, is lacking in them, as we have already remarked, is the Notion. Severance, emanation, effluence or process, emergence, occurrence, are words which in modern times have also had to stand for much, but in fact nothing is expressed by them. Scepticism and dogmatism, as consciousness or knowledge, establish the opposition of subjectivity and objectivity. Plotinus has rejected it, has soared upwards into the highest region, into the Aristotelian thought of Thought; he has much more in common with Aristotle than with Plato, and thereby he is not dialectic, nor does he proceed out of himself, nor as consciousness does he go back out of himself into himself again. With this, in the second place, there is connected the fact that the further descent either to nature or to manifested consciousness, even when expressed as the operation of the higher soul, yet contains much that is arbitrary, and is devoid of the necessity of the Notion; for that which ought to be defined in Notions is expressed in many-coloured pictures, in the form of a reality; and this, to say the least, is a useless and inadequate expression. I quote one example only: our soul belongs not only to the sphere of the finite understanding, where it was perfect, happy, lacking nothing; its power of thought alone belongs to the first, the finite understanding. Its power of motion, or itself looked on as life, had as its source the intelligent world-soul, but sensation had its source in the soul of the world of sensation. That is to say, Plotinus makes the first world-soul to be the immediate activity of the finite understanding, which is an object to itself; it is pure soul above the sublunar region, and dwells in the upper heaven of the fixed stars. This world-soul has power to originate; from it again there flows an entirely sensuous soul. The desire of the individual and particular soul separated from the whole gives it a body; this it receives in the higher region of the heavens. With this body it obtains fancy and memory. At last it repairs to the soul of the sensible world; and from this it acquires sensation, desires, and the life that is vegetative in nature.[244]
This declension, this further step towards the corporeality of the soul, is described by the followers of Plotinus as if the soul sank from the Milky Way and the Zodiac into the orbits of planets which have their place lower down, and in each of these it receives new powers, and in each begins also to exercise these powers. In Saturn the soul first acquires the power of forming conclusions with regard to things; in Jupiter it receives the power of effectiveness of the will; in Mars, affections and impulses; in the Sun, sensation, opinion, and imagination; in Venus, sensuous desires aiming at the particular; in the Moon, lastly, the power of production.[245] In such a way as this Plotinus makes into a particular existence for the spiritual the very things that he declares to be, on the one hand, intelligible moments. The soul which only has desires is the beast; that which only vegetates, which has only power of reproduction, is the plant. But what we spoke of above are not particular conditions of mind, outside of the universal spirit, in the world-spirit’s particular stages of its self-consciousness regarding itself; and Saturn and Jupiter have nothing further to do with it. When they in their potency are expressed as moments of the soul, this is not a whit better than when each of them was supposed to express a particular metal. As Saturn expresses lead, Jupiter tin, and so forth, so Saturn also expresses argumentation, Jupiter will, &c. It is doubtless easier to say that Saturn corresponds with lead, &c., that it is the power of drawing conclusions, or that it represents lead and the power of drawing conclusions, or anything else you like, instead of expressing its Notion, its essence. The above is a comparison with a thing that in like manner does not express a Notion, but is apparent to the senses, which is laid hold of out of the air, or rather indeed from the ground. Such representations are warped and false; for if we say that this is lead, we mean thereby the essence or the implicitness of lead, with which the soul has an affinity; but this is no longer the sensuous Being which is known as lead, nor has this moment of such a state any reality for the soul.
[3. Porphyry and Iamblichus.]
Porphyry and Iamblichus, who have already been mentioned as the biographers of Pythagoras (Vol. I. p. 197), are distinguished followers of Plotinus. The first, a Syrian, died in 304: the latter, likewise of Syria, in the year 333.[246] Amongst other works by Porphyrius, we possess an “Introduction to the Organon of Aristotle on Genera, Species, and Judgments,” in which his logic is propounded in its principal elements. This work is one which has at all times been the text-book of Aristotelian Logic, and also an authority from which the knowledge of its form has been derived; and our ordinary books of logic contain little more than what is found in this Introduction. The fact that Porphyry devoted himself to logic shows that a determinate form of thought was coming into favour with the Neo-Platonists; but this is something pertaining altogether to the understanding and very formal. Thus we here have the characteristic fact that with the Neo-Platonists the logic of the understanding, the quite empiric treatment of the sciences, is found in conjunction with the entirely speculative Idea, and in respect of practical life with a belief in theurgy, the marvellous and strange: in his life of Plotinus, Porphyry, indeed, describes him a miracle-worker, which statement we, however, must set aside as appertaining to literature.
Iamblichus evinces more mistiness and confusion still; he certainly was a teacher highly esteemed in his time, so that he even received the name of divine instructor; but his philosophic writings form a compilation without much specially to characterize them, and his biography of Pythagoras does not do much credit to his understanding. It was likewise in the Pythagorean philosophy that the Neo-Platonists gloried, and more particularly they revived the form of number-determination which pertains to it. In Iamblichus thought sinks into imagination, the intellectual universe to a kingdom of demons and angels with a classification of the same, and speculation comes down to the methods of magic. The Neo-Platonists called this theurgy (θεουργία); for in the miracle speculation, the divine Idea, is, so to speak, brought into immediate contact with actuality, and not set forth in a universal way. As to the work De mysteriis Ægyptiorum, it is not known for certain whether it had Iamblichus as its author or not; later on Proclus makes great ado concerning him, and testifies that he was indebted to Iamblichus for his main ideas.[247]
[4. Proclus.]
Proclus, a later Neo-Platonist who has still to be mentioned, is more important. He was born in 412 at Constantinople, but carried on his studies and spent most of his life with Plutarchus in Athens, where he also died in 485. His life is written by Marinus, in a style similar to that of the biographies just mentioned. According to this his parents came from Xanthus in Lycia, a district of Asia Minor; and since Apollo and Minerva were the tutelary deities of this town, he rendered grateful worship to them. They, themselves, vouchsafed to him, as their favourite, particular regard and personal manifestations; indeed, he was healed of an illness by Apollo touching his head; by Minerva, however, he was called upon to go to Athens. First of all he went to Alexandria to study rhetoric and philosophy, and then to Athens, to be with Plutarchus and Syrianus, the Platonists. Here he first studied Aristotelian and then Platonic philosophy. Above all the daughter of Plutarchus, Asclepigenia, initiated him into the profound secrets of philosophy; she, as Marinus assures us, was the only individual at that time who retained the knowledge, transmitted to her by her father, of the mystic ceremonies and of the whole theurgic discipline. Proclus studied everything pertaining to the mysteries, the Orphic hymns, the writings of Hermes, and religious institutions of every kind, so that, wherever he went, he understood the ceremonies of the pagan worship better than the priests who were placed there for the purpose of performing them. Proclus is said to have had himself initiated into all the pagan mysteries. He himself kept all the religious festivals and observances pertaining to nations the most various; he was even familiar with the Egyptian form of worship, observed the Egyptian days of purification and festivals, and spent certain fast days in offering up prayers and praise. Proclus himself composed many hymns—of which we still possess some that are very beautiful—both in honour of the better known divinities and of those whose fame is entirely local. Of the circumstance that he—“the most God-fearing man”—had dealings with so many religions, he himself says: “It is not fitting for a philosopher to be minister (θεραπευτήν) to the worship of one town or of what pertains to the few, for he should be the universal hierophant of the whole world.” He considered Orpheus to be the originator of all Greek theology, and set a specially high value on the Orphic and Chaldaic oracles. It was in Athens that he taught. Of course his biographer, Marinus, relates the most marvellous things about him, that he brought down rain from heaven and tempered great heat, that he stilled the earthquake, healed diseases, and beheld visions of the divine.[248]
Proclus led a most intellectual life; he was a profoundly speculative man, and the scope of his knowledge was very great. In his case, as also in that of Plotinus, the contrast between the insight of such philosophers and what their disciples relate of them in biographies, must strike one very forcibly, for of the wonders described by the biographers few traces are to be found in the works of the subjects themselves. Proclus left behind him a great number of writings, many of which we now possess; he was the author of several mathematical works which we also have, such as that on the Sphere. His more important philosophic works are the Commentaries on Plato’s Dialogues, certain of which have been published from time to time; that on the Timæus was the most famous. But several were only found in manuscript, and of these Cousin issued in Paris the Commentaries on the Alcibiades (Vols. II. III.), and the Parmenides (Vols. IV.-VI.) for the first time. The first volume of Cousin’s edition contains some writings by Proclus which now exist only in Latin, on Freedom, Providence, and Evil. Works separately published are his important writings, The Platonic Theology (εἰς τὲν Πλάτωνος θεολογίαν) and his Theological Elements (συοιχείωσις θεολογική); the latter short work Creuzer has had re-published, as also some of the before-mentioned Commentaries.
Proclus lived, so to speak, in the worship of science. We cannot fail to see in him great profundity of perception, and greater capacity for working a matter out and clearness of expression than are found in Plotinus; scientific development also advanced with him, and on the whole he possesses an excellent manner of expression. His philosophy, like that of Plotinus, has the form of a Commentary on Plato; his book “On the Theology of Plato,” is in this respect his most interesting work. The main ideas of his philosophy may easily be recognized from this work, which possesses many difficulties for this reason in particular, that in it the pagan gods are considered, and philosophic significations derived from them. But he distinguishes himself entirely from Plotinus by the fact that with him the Neo-Platonic philosophy, as a whole, has at least reached a more systematic order, and also a more developed form; thus in his Platonic theology especially (dialectic as the work undoubtedly is) a more distinct progression and distinction between the spheres in the Idea is to be found, than is noticeable in Plotinus. His philosophy is an intellectual system; we must see how we can work it out. His way of putting it is not perfectly clear, but leaves much to be desired.
