CHAPTER V.
THE SPIRITUALISM OF PLOTINUS.

I.

Among the most interesting of Plutarch’s religious writings is one entitled On the Delays in the Divine Vengeance. As might be expected from the name, it deals with a problem closely akin to that which ages before had been made the subject of such sublime imagery and such inconclusive reasoning by the author of the Book of Job. What troubled the Hebrew poet was the apparently undeserved suffering of the just. What the Greek moralist feels himself called on to explain is the apparent prosperity and impunity of the wicked. He will not for a moment admit that crime remains unavengeful; his object is to show why the retribution does not follow directly on the deed. And, in order to account for this, he adduces a number of very ingenious reasons. By acting deliberately rather than in blind anger, the gods wish to read us a useful lesson in patience and forbearance. Sometimes their object is to give the sinner an opportunity for repentance and amendment; or else they may be holding him in reserve for the performance of some beneficial work. At other times, their justice is delayed only that it may be manifested by some signal and striking form of retribution. In many cases, the final stroke has been preceded by long years of secret torment; and even where no suffering seems to be inflicted, the pangs of remorse may furnish a sufficient expiation. Or again, vengeance may be reserved for a future generation. Some persons hold that to visit the sins of the fathers on the children is unjust, but in this they are profoundly mistaken. Members of the same family and citizens of the same state are connected as parts of one organic whole; sharing in the benefits which accrue from the good deeds of their predecessors, it is right that they should also share in the responsibility for their crimes. Moreover, the posterity of the wicked inherit a sinful disposition which, as the gods can clearly foresee, would betray itself in overt acts were they not cut off in their youth. And it is equally an error to suppose that the original wrongdoers remain unaffected by the retribution which befalls their descendants. On the contrary, they witness it from the next world, where it adds poignancy to their remorse, and entails on them fresh penalties over and above those which they have already been doomed to suffer.

Thus with Plutarch, as with his master Plato, a future world is the grand court of appeal from the anomalies and inequalities of this world; and, following the example of the Gorgias and the Republic, he reserves to the last a terrible picture of the torments held in store for those who have not expiated their transgressions on earth, describing them as they are supposed to have been witnessed by a human soul temporarily separated from the body for the purpose of viewing and reporting on this final manifestation of divine justice. It would appear, however, from the narrative in question that future punishments are not eternal. After a more or less protracted period of expiation, the immortal soul is restored to the upper world, under whatever embodiment seems most appropriate to its former career. Among those whose turn has arrived for entering on a new existence at the moment when Plutarch’s visitor makes his descent to hell, is the soul of Nero. The wicked Emperor has just been condemned to assume the form of a viper, when a great light shines forth, and from the midst of the light a voice is heard crying: ‘Let him reappear under the guise of a song-bird haunting the neighbourhood of marshes and meres; for he has already paid the penalty of his guilt, and the gods owe him some kindness for having liberated Greece, the best and most beloved by them of all the nations that he ruled.’

It would seem from this singular and touching expression of gratitude that the deathless idealism of Hellas found in Nero’s gift of a nominal liberty ample compensation for the very real and precious works of art of which she was despoiled on the occasion of his visit to her shores. At first sight, that visit looks like nothing better than a display of triumphant buffoonery on the one side and of servile adulation on the other. But, in reality, it was a turning-point in the history of civilisation, the awakening to new glories of a race in whom life had become, to all outward appearance, extinct. For more than a whole century the seat of intellectual supremacy had been established in Rome; and during the same period Rome herself had turned to the West rather than to the East for renovation and support. Caesar’s conquests were like the revelation of a new world; and three times over, when the two halves of the divided empire came into collision, the champion who commanded the resources of that world had won. Henceforth it was to her western provinces and to her western frontiers that Rome looked for danger, for aggrandisement, or for renown. In Horace’s time, men asked each other what the warlike Cantabrians were planning; and the personal presence of Augustus himself was needed before those unruly Iberians could be subdued. His adopted sons earned their first laurels at the expense of Alpine mountaineers. His later years are filled with German campaigns; and the great disaster of Varus must have riveted attention more closely than any victory to what was passing between the Rhine and the Elbe. Under Claudius, the conquest of Britain opened a new source of interest in the West, and, like Germany before, supplied a new title of triumph to the imperial family. Half the literary talent in Rome, the two Senecas, Lucan, and at a later period Martial and Quintilian, came from Spain, as also did Trajan, whose youth fall in this period.

With Nero’s visit to Greece in 66 the reaction begins. When, a few years later, the empire was disputed between a general from Gaul and a general from Syria, it was the candidate of the Eastern legions who prevailed; the revolt of Judaea drew attention to Eastern affairs; and the great campaigns of Trajan must have definitely turned the tide of public interest in that direction, notwithstanding the far-sighted protest of Tacitus. On more peaceful ground, Hadrian’s Asiatic tours and his protracted residence in Athens completed the work inaugurated by Nero. In his reign, the intellectual centre of gravity is definitely transferred to Greece; and Roman literature, after its last blaze of splendour under Trajan, becomes extinct, or survives only in forms borrowed from the sophistical rhetoric of the East.

Plutarch, who was twenty-one when Nero declared his country free, was the first leader in the great Hellenist revival, without, at the same time, entirely belonging to it. He cared more for the matter than for the form of antiquity, for the great deeds and greater thoughts of the past than for the words in which they were related and explained. Hence, by the awkwardness and heaviness of his style, he is more akin to the writers of the Alexandrian period than to his immediate successors. On the one side, he opens the era of classical idealism; on the other, he closes that of encyclopaedic erudition. The next generation bore much the same relation to Plutarch that the first Sophists bore to Hecataeus and Herodotus. Addressing themselves to popular audiences, they were obliged to study perspicuity and elegance of expression, at the risk, it is true, of verbosity and platitude. Such men were Dion Chrysostom, Herôdes Atticus, Maximus Tyrius, and Aristeides. But the old models were imitated with more success by writers who lived more entirely in the past. Arrian reproduced the graceful simplicity of Xenophon in his narrative of the campaigns of Alexander and his reports of the lectures of Epictêtus. Lucian composed dialogues ranking with the greatest masterpieces of lighter Attic literature. The felicity of his style and his complete emancipation from superstition may probably be traced to the same source—a diligent study of the ancient classics. It is certain that neither as a writer nor as a critic does he represent the average educated taste of his own times. So far from giving polytheism its deathblow, as he was formerly imagined to have done, he only protested unavailingly against its restoration.

Not only oratory and literature, but philosophy and science were cultivated with renewed vigour. The line between philosophy and sophisticism was not, indeed, very distinctly drawn. Epictêtus severely censures the moral teachers of his time for ornamenting their lectures with claptrap rhetoric about the battle of Thermopylae or flowery descriptions of Pan and the Nymphs.406 And the professed declaimers similarly drew on a store of philosophical commonplaces. This sort of popular treatment led to the cultivation of ethics and theology in preference to logic and metaphysics, and to an eclectic blending of the chief systems with one another. A severer method was inculcated in the schools of Athens, especially after the endowment of their professors by Marcus Aurelius; but, in practice, this came to mean what it means in modern universities, the substitution of philology for independent enquiry. The question was not so much what is true as what did Plato or Aristotle really think. Alexandrian science showed something of the same learned and traditional character in the works of Ptolemy; but the great name of Galen marks a real progress in physiology, as well as a return to the principles of Hippocrates.

Thus, so far as was possible in such altered circumstances, did the Renaissance of the second century reproduce the intellectual environment from which Plato’s philosophy had sprung. In literature, there was the same attention to words rather than to things; sometimes taking the form of exact scholarship, after the manner of Prodicus; sometimes of loose and superficial declamation, after the manner of Gorgias. There was the naturalism of Hippias, elaborated into a system by the Stoics, and practised as a life by the new Cynics. There was the hedonism of Aristippus, inculcated under a diluted form by the Epicureans. There was the old Ionian materialism, professed by Stoics and Epicureans alike. There was the scepticism of Protagoras, revived by Aenesidêmus and his followers. There was the mathematical mysticism of the Pythagoreans, flourishing in Egypt instead of in southern Italy. There was the purer geometry of the Alexandrian Museum, corresponding to the school of Cyrênê. On all sides, there was a mass of vague moral preaching, without any attempt to exhibit the moral truths which we empirically know as part of a comprehensive metaphysical philosophy. And, lastly, there was an immense undefined religious movement, ranging from theologies which taught the spirituality of God and of the human soul, down to the most irrational and abject superstition. We saw in the last chapter how, corresponding to this environment, there was a revived Platonism, that Platonism was in fact the fashionable philosophy of that age, just as it afterwards became the fashionable philosophy of another Renaissance thirteen centuries later. But it was a Platonism with the backbone of the system taken out. Plato’s thoughts all centred in a carefully considered scheme for the moral and political regeneration of society. Now, with the destruction of Greek independence, and the absorption everywhere of free city-states into a vast military empire, it might seem as if the realisation of such a scheme had become altogether impracticable. The Republic was, indeed, at that moment realising itself under a form adapted to the altered exigencies of the time; but no Platonist could as yet recognise in the Christian Church even an approximate fulfilment of his master’s dream. Failing any practical issue, there remained the speculative side of Plato’s teaching. His writings did not embody a complete system, but they offered the materials whence a system could be framed. Here the choice lay between two possible lines of construction; and each had, in fact, been already attempted by his own immediate disciples. One was the Pythagorean method of the Old Academy, what Aristotle contemptuously called the conversion of philosophy into mathematics. We saw in the last chapter how the revived Platonism of the first and second centuries entered once more on the same perilous path, a path which led farther and farther away from the true principles of Greek thought, and of Plato himself when his intellect stood at its highest point of splendour. Neo-Pythagorean mysticism meant an unreconciled dualism of spirit and matter; and as the ultimate consequence of that dualism, it meant the substitution of magical incantations and ceremonial observances for the study of reason and virtue. Moreover, it readily allied itself with Oriental beliefs, which meant a negation of natural law that the Greeks could hardly tolerate, and, under the form of Gnostic pessimism, a belief in the inherent depravity of Nature that they could not tolerate at all.

The other alternative was to combine the dialectical idealism of Plato with the cosmology of early Greek thought, interpreting the two worlds of spirit and Nature as gradations of a single series and manifestations of a single principle. This was what Aristotle had attempted to do, but had not done so thoroughly as to satisfy the moral wants of his own age, or the religious wants of the age when a revived Platonism was seeking to organise itself into a system which should be the reconciliation of reason and faith. Yet the better sort of Platonists felt that this work could not be accomplished without the assistance of Aristotle, whose essential agreement with their master, as against Stoicism, they fully recognised. Their mistake was to assume that this agreement extended to every point of his teaching. Taken in this sense, their attempted harmonies were speedily demolished by scholars whose professional familiarity with the original sources showed them how strongly Aristotle himself had insisted on the differences which separated him from the Academy and its founder.407 To identify the two great spiritualist philosophers being impossible, it remained to show how they could be combined. The solution of such a problem demanded more genius than was likely to be developed in the schools of Athens. An intenser intellectual life prevailed in Alexandria, where the materials of erudition were more abundantly supplied, and where contact with the Oriental religions gave Hellenism a fuller consciousness of its distinction from and superiority to every other form of speculative activity. And here, accordingly, the fundamental idea of Neo-Platonism was conceived.

II.

Plotinus is not only the greatest and most celebrated of the Neo-Platonists, he is also the first respecting whose opinions we have any authentic information, and therefore the one who for all practical purposes must be regarded as the founder of the school. What we know about his life is derived from a biography written by his disciple Porphyry. This is a rather foolish performance; but it possesses considerable interest, both on account of the information which it was intended to supply, and also as affording indirect evidence of the height to which superstition had risen during the third century of our era. Plotinus gave his friends to understand that he was born in Egypt about 205 A.D.; but so reluctant was he to mention any circumstance connected with his physical existence, that his race and parentage always remained a mystery. He showed somewhat more communicativeness in speaking of his mental history, and used to relate in after-life that at the age of twenty-eight he had felt strongly attracted to the study of philosophy, but remained utterly dissatisfied with what the most famous teachers of Alexandria had to tell him on the subject. At last he found in Ammonius Saccas the ideal sage for whom he had been seeking, and continued to attend his lectures for eleven years. At the end of that period, he joined an eastern expedition under the Emperor Gordian, for the purpose of making himself acquainted with the wisdom of the Persians and Indians, concerning which his curiosity seems to have been excited by Ammonius. But his hopes of further enlightenment in that quarter were not fulfilled. The campaign terminated disastrously; the emperor himself fell at the head of his troops in Mesopotamia, and Plotinus had great difficulty in escaping with his life to Antioch. Soon afterwards he settled in Rome, and remained there until near the end of his life, when ill-health obliged him to retire to a country seat in Campania, the property of a deceased friend, Zêthus. Here the philosopher died, in the sixty-sixth year of his age.

Plotinus seems to have begun his career as a public teacher soon after taking up his residence in Rome. His lectures at first assumed the form of conversations with his private friends. Apparently by way of reviving the traditions of Socrates and Plato, he encouraged them to take an active part in the discussion: but either he did not possess the authority of his great exemplars, or the rules of Greek dialogue were not very strictly observed in Rome; for we learn from the report of an eye-witness that interruptions were far too frequent, and that a vast amount of nonsense was talked.408 Afterwards a more regular system of lecturing was established, and papers were read aloud by those who had any observations to offer, as in our own philosophical societies.

The new teacher gathered round him a distinguished society, comprising not only professional philosophers, but also physicians, rhetors, senators, and statesmen. Among the last-mentioned class, Rogatianus, who filled the office of praetor, showed the sincerity of his conversion by renouncing the dignities of his position, surrendering his worldly possessions, limiting himself to the barest necessaries of life, and allowing himself to be dependent even for these on the hospitality of his friends. Thanks to this asceticism, he recovered the use of his hands and feet, which had before been completely crippled with gout.409

The fascination exercised by Plotinus was not only intellectual, but personal. Singularly affable, obliging, and patient, he was always ready to answer the questions of his friends, even laying aside his work in order to discuss the difficulties which they brought to him for solution. His lectures were given in Greek; and although this always remained to him a foreign language, the pronunciation and grammar of which he never completely mastered, his expressions frequently won admiration by their felicity and force; and the effect of his eloquence was still further heightened by the glowing enthusiasm which irradiated his whole countenance, naturally a very pleasing one, during the delivery of the more impressive passages.410

As might be expected, the circle of admirers which surrounded Plotinus included several women, beginning with his hostess Gemina and her daughter. He also stood high in the favour of the Emperor Galienus and his consort Salonina; so much so, indeed, that they were nearly persuaded to let him try the experiment of restoring a ruined city in Campania, and governing it according to Plato’s laws.411 Porphyry attributes the failure of this project to the envy of the courtiers; Hegel, with probably quite as much reason, to the sound judgment of the imperial ministers.412

Our philosopher had, however, abundant opportunity for showing on a more modest scale that he was not destitute of practical ability. So high did his character stand, that many persons of distinction, when they felt their end approaching, brought their children to him to be taken care of, and entrusted their property to his keeping. As a result of the confidence thus reposed in him, his house was always filled with young people of both sexes, to whose education and material interests he paid the most scrupulous attention, observing that as long as his wards did not make a profession of philosophy, their estates and incomes ought to be preserved unimpaired. It is also mentioned that, although frequently chosen to arbitrate in disputes, he never made a single enemy among the Roman citizens—a piece of good fortune which is more than one could safely promise to anyone similarly circumstanced in an Italian city at the present day.413

Plotinus possessed a remarkable power of reading the characters and even the thoughts of those about him. It is said, probably with some exaggeration, that he predicted the future fate of all the boys placed under his care. Thus he foretold that a certain Polemo, in whom he took particular interest, would devote himself to love and die young; which proved only too true, and may well have been anticipated by a good observer without the exercise of any supernatural prescience. As another instance of his penetration, we are told that a valuable necklace having been stolen from a widow named Chione, who lived in his house with her family, the slaves were all led into the presence of Plotinus that he might single out the thief. After a careful scrutiny, the philosopher put his finger on the guilty individual. The man at first protested his innocence, but was soon induced by an application of the whip to confess, and, what was a much more valuable verification of his accuser’s insight, to restore the missing article. Porphyry himself could testify from personal experience to his friend’s remarkable power of penetration. Being once about to commit suicide, Plotinus divined his intention, and told him that it proceeded, not from a rational resolution, but from a fit of the blues, as a remedy for which he prescribed change of scene, and this did in fact have the desired effect.414

Previous to his forty-ninth year, Plotinus wrote nothing. At that age he began to compose short essays on subjects which suggested themselves in the course of his oral teaching. During the next ten years, he produced twenty-one such papers, some of them only a page or two in length. At the end of that period, he made the acquaintance of his future editor and biographer, Porphyry, a young student of Semitic extraction, whose original name was Malchus. The two soon became fast friends; and whatever speculative differences at first divided them were quickly removed by an amicable controversy between Porphyry and another disciple named Amelius, which resulted in the unreserved adhesion of the former to the doctrine of their common master.415 The literary activity of Plotinus seems to have been powerfully stimulated by association with the more methodical mind of Porphyry. During the five years416 of their personal intercourse he produced nineteen essays, amounting altogether to three times the bulk of the former series. Eight shorter pieces followed during the period of failing health which preceded his death, Porphyry being at that time absent in Sicily, whither he had retired when suffering from the fit of depression already mentioned.

Porphyry observes that the first series of essays show the immaturity of youth—a period which he extends to what is generally considered the sufficiently ripe age of fifty-nine;—the second series the full-grown power of manhood; and the last the weakness of declining years. The truth is that his method of criticism, at least in this instance, was to judge of compositions as if their merit depended on their length, and perhaps also with reference to the circumstance whether their subject had or had not been previously talked over with himself. In point of fact, the earlier pieces include some of the very best things that Plotinus ever wrote; and, taking them in the order of their composition, they form a connected exposition of Neo-Platonic principles, to which nothing of importance was ever added. This we shall attempt to show in the most effectual manner possible by basing our own account of Neo-Platonism on an analysis of their contents; and we strongly recommend them to the attention of all Greek scholars who wish to make themselves acquainted with Plotinus at first hand, but have not leisure to wade through the whole of his works. It may also be mentioned that the last series of essays are distinguished by the popular character of their subjects rather than by any evidence of failing powers, one of them, that on Providence,417 being remarkable for the vigour and eloquence of its style.

By cutting up some of the longer essays into parts, Porphyry succeeded, much to his delight, in bringing the whole number up to fifty-four, which is a product of the two perfect numbers six and nine. He then divided them into six volumes, each containing nine books—the famous Enneads of Plotinus. His principle of arrangement was to bring together the books in which similar subjects were discussed, placing the easier disquisitions first. This disposition has been adhered to by subsequent editors, with the single exception of Kirchhoff, who has printed the works of Plotinus according to the order in which they were written.418 Porphyry’s scrupulous information has saved modern scholars an incalculable amount of trouble, but has not, apparently, earned all the gratitude it deserved, to judge by Zeller’s intimation that the chronological order of the separate pieces cannot even now be precisely determined.419 Unfortunately, what could have been of priceless value in the case of Plato and Aristotle, is of comparatively small value in the case of Plotinus. His system must have been fully formed when he began to write, and the dates in our possession give no clue to the manner in which its leading principles were evolved.420

Such, so far as they can be ascertained, are the most important facts in the life of Plotinus. Interwoven with these, we find some legendary details which vividly illustrate the superstition and credulity of the age. It is evident from his childish talk about the numbers six and nine that Porphyry was imbued with Pythagorean ideas. Accordingly, his whole account of Plotinus is dominated by the wish to represent that philosopher under the guise of a Pythagorean saint. We have already alluded to the manner in which he exalts his hero’s remarkable sagacity into a power of supernatural prescience and divination. He also tells us, with the most unsuspecting good faith, how a certain Alexandrian philosopher whose jealousy had been excited by the success of his illustrious countryman, endeavoured to draw down the malignant influences of the stars on the head of Plotinus, but was obliged to desist on finding that the attack recoiled on himself.421 On another occasion, an Egyptian priest, by way of exhibiting his skill in magic, offered to conjure up the daemon or guardian spirit of Plotinus. The latter readily consented, and the Temple of Isis was chosen for the scene of the operations, as, according to the Egyptian, no other spot sufficiently pure for the purpose could be found in Rome. The incantations were duly pronounced, when, much to the admiration of those present, a god made his appearance instead of the expected daemon. By what particular marks the divinity of the apparition was determined, Porphyry omits to mention. The philosopher was congratulated by his countryman on the possession of such a distinguished patron, but the celestial visitor vanished before any questions could be put to him. This mishap was attributed to a friend ‘who, either from envy or fear, choked the birds which had been given him to hold,’ and which seem to have played a very important part in the incantation, though what it was, we do not find more particularly specified.422

Another distinguished compliment was paid to Plotinus after his death by no less an authority than the Pythian Apollo, who at this period had fully recovered the use of his voice. On being consulted respecting the fate of the philosopher’s soul, the god replied by a flood of bombastic twaddle, in which the glorified spirit of Plotinus is described as released from the chain of human necessity and the surging uproar of the body, swimming stoutly to the storm-beaten shore, and mounting the heaven-illumined path, not unknown to him even in life, that leads to the blissful abodes of the immortals.423

In view of such tendencies, one hardly knows how much confidence is to be placed in Porphyry’s well-known picture of his master as one who lived so entirely for spiritual interests that he seemed ashamed of having a body at all. We are told that, as a consequence of this feeling, he avoided the subject of his past life, refused to let his portrait be painted, neglected the care of his health, and rigorously abstained from animal food, even when it was prescribed for him under the form of medicine.424 All this may be true, but it is not very consistent with the special doctrines of Plotinus as recorded in his writings, nor should it be allowed to influence our interpretation of them. In his personal character and conduct he may have allowed himself to be carried away by the prevalent asceticism and superstition of the age; in his philosophy he is guided by the healthier traditions of Plato and Aristotle, and stands in declared opposition to the mysticism which was a negation of Nature and of life.

How far Plotinus was indebted to Ammonius Saccas for his speculative ideas is another question with respect to which the Pythagoreanising tendencies of his biographer may possibly have contributed to the diffusion of a serious misconception. What Porphyry tells us is this. Before leaving Alexandria, Plotinus had bound himself by a mutual agreement with two of his fellow-pupils, Herennius and Origines (not the Christian Father, but a pagan philosopher of the same age and name), to keep secret what they had learned by listening to the lectures of Ammonius. Herennius, however, soon broke the compact, and Origines followed his example. Plotinus then considered that the engagement was at an end, and used the results of his studies under Ammonius as the basis of his conversational lectures in Rome, the substance of which, we are left to suppose, was subsequently embodied in his published writings. But, as Zeller has pointed out, this whole story bears a suspicious resemblance to what is related of the early Pythagorean school. There also the doctrines of the master were regarded by his disciples as a mystery which they pledged themselves to keep secret, and were only divulged through the infidelity of one among their number, Philolaus. And the same critic proves by a careful examination of what are known to have been the opinions of Origines and Longinus, both fellow-pupils of Plotinus, that they differed from him on some points of essential importance to his system. We cannot, therefore, suppose that these points were included in the teaching of their common master, Ammonius.425 But if this be so, it follows that Plotinus was the real founder of the Neo-Platonic school; and, in all cases, his writings remain the great source whence our knowledge of its first principles is derived.

III.

In point of style, Plotinus is much the most difficult of the ancient philosophers, and, in this respect, is only surpassed by a very few of the moderns. Even Longinus, who was one of the most intelligent critics then living, and who, besides, had been educated in the same school with our philosopher, could not make head or tail of his books when copies of them were sent to him by Porphyry, and supposed, after the manner of philologists, that the text must be corrupt, much to the disgust of Porphyry, who assures us that its accuracy was unimpeachable.426 Probably politeness prevented Longinus from saying, what he must have seen at a glance, that Plotinus was a total stranger to the art of literary composition. We are told that he wrote as fast as if he were copying from a book; but he had never mastered even the elements of the Greek language; and the weakness of his eyesight prevented him from reading over what he had written. The mistakes in spelling and grammar Porphyry corrected, but it is evident that he has made no alterations in the general style of the Enneads; and this is nearly as bad as bad can be—disjointed, elliptical, redundant, and awkward. Chapter follows chapter and paragraph succeeds to paragraph without any fixed principle of arrangement; the connexion of the sentences is by no means clear; some sentences are almost unintelligible from their extreme brevity, others from their inordinate length and complexity. The unpractised hand of a foreigner constantly reveals itself in the choice and collocation of words and grammatical inflections. Predicates and subjects are huddled together without any regard to the harmonies of number and gender, so that even if false concords do not occur, we are continually annoyed by the suggestion of their presence.427

But even the most perfect mastery of Greek would not have made Plotinus a successful writer. We are told that before taking up the pen he had thoroughly thought out his whole subject; but this is not the impression produced by a perusal of the Enneads. On the contrary, he seems to be thinking as he goes along, and to be continually beset by difficulties which he has not foreseen. The frequent and disorderly interruptions by which his lectures were at one time disturbed seem to have made their way into his solitary meditations, breaking or tangling the thread of systematic exposition at every turn. Irrelevant questions are constantly intruding themselves, to be met by equally irrelevant answers. The first mode of expressing an idea is frequently withdrawn, and another put in its place, which is, in most cases, the less intelligible of the two; while, as a general rule, when we want to know what a thing is, Plotinus informs us with indefatigable prolixity what it is not.

Nevertheless, by dint of pertinacious repetition, the founder of Neo-Platonism has succeeded in making the main outlines, and to a great extent the details, of his system so perfectly clear that probably no philosophy is now better understood than his. In this respect, Plotinus offers a remarkable contrast to the two great thinkers from whom his ideas are principally derived. While Plato and Aristotle construct each particular sentence with masterly clearness, the general drift of their speculations is by no means easy to ascertain; and, even now, critics take diametrically opposite views of the interpretation which is to be put on their teaching with regard to several most important points. The expositors of Neo-Platonism, on the contrary, show a rare unanimity in their accounts of its constitutive principles. What they differ about is its origin and its historical significance. And these are points on which we too shall have to enter, since all the ancient systems are interesting to us chiefly as historical phenomena, and Neo-Platonism more so than any other. Plotinus effected a vast revolution in speculative opinion, but he effected it by seizing on the thoughts of others rather than by any new thoughts or even new developments or applications of his own.

Whether Plotinus was or was not the disciple of Ammonius, it is beyond all doubt that he considered himself the disciple of Plato. There are more than a hundred references to that philosopher in the Enneads, against less than thirty references to all the other ancient thinkers put together;428 and, what is more remarkable, in only about half of them is he mentioned by name. The reader is expected to know that ‘he’ always means Plato. And it is an article of faith with Plotinus that his master cannot be mistaken; when the words of oracular wisdom seem to contradict one another, there must be some way of harmonising them. When they contradict what he teaches himself, the difficulty must be removed by skilful interpretation; or, better still, it must be discreetly ignored.429 On the other hand, when a principle is palpably borrowed from Aristotle, not only is its derivation unacknowledged, but we are given to understand by implication that it belongs to the system which Aristotle was at most pains to controvert.430

But numerous as are the obligations, whether real or imaginary, of the Alexandrian to the Athenian teacher, they range over a comparatively limited field. What most interests a modern student in Platonism—its critical preparation, its conversational dialectic, its personal episodes, its moral enthusiasm, its political superstructure—had apparently no interest for Plotinus as a writer. He goes straight to the metaphysical core of the system, and occupies himself with re-thinking it in its minutest details. Now this was just the part which had either not been discussed at all, or had been very insufficiently discussed by his predecessors. It would seem that the revival of Platonic studies had followed an order somewhat similar to the order in which Plato’s own ideas were evolved. The scepticism of the Apologia had been taken up and worked out to its last consequences by the New Academy. The theory of intuitive knowledge, the ethical antithesis between reason and passion, and the doctrine of immortality under its more popular form, had been resumed by the Greek and Roman Eclectics. Plutarch busied himself with the erotic philosophy of the Phaedrus and the Symposium, as also did his successor, Maximus Tyrius. In addition to this, he and the other Platonists of the second century paid great attention to the theology adumbrated in those dialogues, and in the earlier books of the Republic. But meanwhile Neo-Pythagoreanism had intervened to break the normal line of development, and, under its influence, Plutarch passed at once to the mathematical puzzles of the Timaeus. With Plato himself the next step had been to found a state for the application of his new principles; and such was the logic of his system, that the whole stress of adverse circumstances could not prevent the realisation of a similar scheme from being mooted in the third century; while, as we have seen, something more remotely analogous to it was at that very time being carried out by the Christian Church. Plato’s own disappointed hopes had found relief in the profoundest metaphysical speculations; and now the time has come when his labours in this direction were to engage the attention hitherto absorbed by the more popular or literary aspects of his teaching.

Now it was by this side of Platonism that Aristotle also had been most deeply fascinated. While constantly criticising the ideal theory, he had, in truth, accepted it under a modified form. His universal classification is derived from the dialectic method. His psychology and theology are constructed on the spiritualistic basis of the Academy, and out of materials which the founder of the Academy had supplied. It was therefore natural that Plotinus should avail himself largely of the Stagirite’s help in endeavouring to reproduce what a tradition of six centuries had obscured or confused. To reconcile the two Attic masters was, as we know, a common school exercise. Learned commentators had, indeed, placed their disagreement beyond all dispute. But there remained the simpler course of bringing their common standpoint into greater prominence, and combining their theories where this seemed possible without too openly renouncing the respect due to what almost all considered the superior authority of Plato. To which of the two masters Neo-Platonism really owed most is a question that must be postponed until we have made ourselves acquainted with the outlines of the system as they appear in the works of Plotinus.

IV.

It has been already mentioned how large a place was given to erotic questions by the literary Platonists of the second century. Even in the school of Plotinus, Platonic love continued to be discussed, sometimes with a freedom which pained and disgusted the master beyond measure.431 His first essay was apparently suggested by a question put to him in the course of some such debate.432 The subject is beauty. In his treatment of it, we find our philosopher at once rising superior to the indecorous frivolities of his predecessors. Physical beauty he declares to be the ideal element in objects, that which they have received from the creative soul, and which the perceptive soul recognises as akin to her own essence. Love is nothing but the excitement and joy occasioned by this discovery. But to understand the truer and higher forms of beauty, we must turn away from sensible perceptions, and study it as manifested in wise institutions, virtuous habits, and scientific theories. The passionate enthusiasm excited by the contemplation of such qualities as magnanimity, or justice, or wisdom, or valour can only be explained by assuming that they reveal our inmost nature, showing us what we were destined for, what we originally were, and what we have ceased to be. For we need only enumerate the vices which make a soul hideous—injustice, sensuality, cowardice, and the like—to perceive that they are foreign to her real nature, and are imposed on her by contamination with the principle of all evil, which is matter. To be brave means not to dread death, because death is the separation of the soul from the body. Magnanimity means the neglect of earthly interests. Wisdom means the elevation of our thoughts to a higher world. The soul that virtue has thus released becomes pure reason, and reason is just what constitutes her intrinsic beauty. It is also what alone really exists; without it all the rest of Nature is nothing. Thus foul is opposed to fair, as evil to good and false to true. Once more, as the soul is beautiful by participation in reason, so reason in its turn depends on a still higher principle, the absolute good to which all things aspire, and from which they are derived—the one source of life, of reason, and of existence. Behind all other loves is the longing for this ultimate good; and in proportion to its superiority over their objects is the intensity of the passion which it inspires, the happiness which its attainment and fruition must bestow. He who would behold this supreme beauty must not seek for it in the fair forms of the external world, for these are but the images and shadows of its glory. It can only be seen with the inward eye, only found in the recesses of our own soul. To comprehend the good we must be good ourselves; or, what is the same thing, we must be ourselves and nothing else. In this process of abstraction, we first arrive at pure reason, and then we say that the ideas of reason are what constitutes beauty. But beyond reason is that highest good of which beauty is merely the outward vesture, the source and principle from which beauty springs.

It is evident that what Plotinus says about beauty and love was suggested by the well-known passages on the same subject in the Phaedrus and the Symposium. His analysis of aesthetic emotion has, however, a much more abstract and metaphysical character than that of his great model. The whole fiction of an antenatal existence is quietly let drop. What the sight of sensible beauty awakens in a philosophic soul is not the memory of an ideal beauty beheld in some other world, but the consciousness of its own idealising activity, the dominion which it exercises over unformed and fluctuating matter. And, in all probability, Plato meant no more than this—in fact he hints as much elsewhere,433—but he was not able or did not choose to express himself with such unmistakable clearness.

Again, this preference for mythological imagery on the part of the more original and poetical thinker seems to be closely connected with a more vivid interest in the practical duties of life. With Plotinus, the primal beauty or supreme good is something that can be isolated from all other beauty and goodness, something to be perceived and enjoyed in absolute seclusion from one’s fellow-men. God is, indeed, described as the source and cause of all other good. But neither here nor elsewhere is there a hint that we should strive to resemble him by becoming, in our turn, the cause of good to others. Platonic love, on the contrary, first finds its reality and truth in unremitting efforts for the enlightenment and elevation of others, being related to the transmission of spiritual life just as the love inspired by visible beauty is related to the perpetuation and physical ennoblement of the race.

This preference of pure abstract speculation to beneficent action may be traced to the influence of Aristotle. Some of the most enthusiastic expressions used by Plotinus in speaking of his supreme principle seem to have been suggested by the Metaphysics and the last book of the Nicomachean Ethics. The self-thinking thought of the Stagirite does not, indeed, take the highest rank with him. But it is retained in his system, and is only relegated to a secondary place because, for reasons which we shall explain hereafter, it does not fulfil equally well with Plato’s Idea of Good, the condition of absolute and indivisible unity, without which a first principle could not be conceived by any Greek philosopher. But this apparent return to the standpoint of the Republic really involves a still wider departure from its animating spirit. In other words, Plotinus differs from Aristotle as Aristotle himself had differed from Plato; he shares the same speculative tendency, and carries it to a greater extreme.

We have also to note that Plotinus arrives at his Absolute by a method apparently very different from that pursued by either of his teachers. Plato’s primal beauty is, on the face of it, an abstraction and generalisation from all the scattered and imperfect manifestations of beauty to be met with in our objective experience. And Aristotle is led to his conception of an eternal immaterial thought by two lines of analysis, both starting from the phenomena of external Nature. The problem of his Physics is to account for the perpetuity of motion. The problem of his Metaphysics is to explain the transformation of potential into actual existence. Plotinus, on the other hand, is always bidding us look within. What we admire in the objective world is but a reflex of ourselves. Mind is the sole reality; and to grasp this reality under its highest form, we must become like it. Thus the more we isolate our own personality and self-identity from the other interests and experiences of life, the more nearly do we approach to consciousness of and coalescence with the supreme identity wherein all things have their source.

But on looking at the matter a little more closely, we shall find that Plotinus only set in a clearer light what had all along been the leading motive of his predecessors. We have already observed that Plato’s whole mythological machinery is only a fanciful way of expressing that independent experience which the mind derives from the study of its own spontaneous activity. And the process of generalisation described in the Symposium is really limited to moral phenomena. Plato’s standpoint is less individualistic than that of Plotinus in so far as it involves a continual reference to the beliefs, experiences, and wants of other men; but it is equally subjective, in the sense of interpreting all Nature by the analogies of human life. There are even occasions when his spiritualism goes the length of inculcating complete withdrawal from the world of common life into an ideal sphere, when he seems to identify evil with matter, when he reduces all virtue to contempt for the interests of the body, in language which his Alexandrian successor could adopt without any modification of its obvious meaning.434

So also with Aristotle. As a naturalist, he is, indeed, purely objective; but when he offers a general explanation of the world, the subjective element introduced by Protagoras and Socrates at once reappears. Simple absolute self-consciousness is for him the highest good, the animating principle of Nature, the most complete reality, and the only one that would remain, were the element of nonentity to disappear from this world. The utter misconception of dynamic phenomena which marks his physics and astronomy can only be accounted for by his desire to give life the priority over mechanical motion, and reason the priority over life. Thus his metaphysical method is essentially identical with the introspective method recommended by Plotinus, and, if fully worked out, might have led to the same results.

We cannot, then, agree with Zeller, when he groups the Neo-Platonists together with the other post-Aristotelian schools, on the ground that they are all alike distinguished from Plato and Aristotle by the exclusive attention which they pay to subjective and practical, as opposed to scientific and theoretical interests. It seems to us that such distinctions are out of relation to the historical order in which the different systems of Greek philosophy were evolved. It is not in the substance of their teaching, but in their diminished power of original speculation, that the thinkers who came after Aristotle offer the strongest contrast to their predecessors. In so far as they are exclusively practical and subjective, they follow the Humanists and Socrates. In so far as they combine Socratic tendencies with physical studies, they imitate the method of Plato and Aristotle. Their cosmopolitan naturalism is inherited from the Cynics in the first instance, more remotely from the physiocratic Sophists, and, perhaps, in the last resort, from Heracleitus. Their religion is traceable either to Pythagoras, to Socrates, or to Plato. Their scepticism is only a little more developed than that of Protagoras and the Cyrenaics. But if we seek for some one principle held in common by all these later schools, and held by none of the earlier schools, we shall seek for it in vain. The imitative systems are separated from one another by the same fundamental differences as those which divide the original systems. Now, in both periods, the deepest of all differences is that which divides the spiritualists from the materialists. In both periods, also, it is materialism that comes first. And in both, the transition from one doctrine to the other is marked by the exclusive prominence given to subjective, practical, sceptical, or theological interests in philosophy; by the enthusiastic culture of rhetoric in general education; and by a strong religious reaction in the upper ranks of society.

Thus we can quite agree with Zeller when he observes435 that Neo-Platonism only carried out a tendency towards spiritualism which had been already manifesting itself among the later Stoics, and had been still further developed by the Neo-Pythagoreans. But what does this prove? Not what Zeller contends for, which is that Neo-Platonism stands on the same ground with the other post-Aristotelian systems, but simply that a recurrence of the same intellectual conditions was being followed by a recurrence of the same results. Now, as before, materialism was proving its inadequacy to account for the facts of mental experience. Now, as before, morality, after being cut off from physical laws, was seeking a basis in religious or metaphysical ideas. Now, as before, the study of thoughts was succeeding to the study of words, and the methods of popular persuasion were giving place to the methods of dialectical demonstration. Of course, the age of Plotinus was far inferior to the age of Plato in vitality, in genius, and in general enlightenment, notwithstanding the enormous extension which Roman conquest had given to the superficial area of civilisation, as the difference between the Enneads and the Dialogues would alone suffice to prove. But this does not alter the fact that the general direction of their movement proceeds in parallel lines.

In saying that the post-Aristotelian philosophers were not original thinkers, we must guard against the supposition that they contributed nothing of value to thought. On the contrary, while not putting forward any new theories, they generalised some of the principles borrowed from their predecessors, worked out others in minute detail, and stated the arguments on both sides of every controverted point with superior dialectic precision. Thus, while materialism had been assumed as self-evidently true by the pre-Socratic schools, it was maintained by the Stoics and Epicureans on what seemed to be grounds of experience and reason. And, similarly, we find that Plotinus, having arrived at the consciousness that spiritualism is the common ground on which Plato and Aristotle stand, the connecting trait which most completely distinguishes them from their successors, proceeds in his second essay436 to argue the case against materialism more powerfully than it had ever been argued before, and with nearly as much effect as it has ever been argued since.

V.

Our personality, says the Alexandrian philosopher, cannot be a property of the body, for this is composed of parts, and is in a state of perpetual flux. A man’s self, then, is his soul; and the soul cannot be material, for the ultimate elements of matter are inanimate, and it is inconceivable that animation and reason should result from the aggregation of particles which, taken singly, are destitute of both; while, even were it possible, their disposition in a certain order would argue the presence of an intelligence controlling them from without. The Stoics themselves admit the force of these considerations, when they attribute reason to the fiery element or vital breath by which, according to them, all things are shaped. They do, indeed, talk about a certain elementary disposition as the principle of animation, but this disposition is either identical with the matter possessing it, in which case the difficulties already mentioned recur, or distinct from it, in which case the animating principle still remains to be accounted for.

Again, to suppose that the soul shares in the changes of the body is incompatible with the self-identity which memory reveals. To suppose that it is an extended substance is incompatible with its simultaneous presence, as an indivisible whole, at every point to which its activity reaches; as well as with the circumstance that all our sensations, though received through different organs, are referred to a common centre of consciousness. If the sensorium is a fluid body it will have no more power of retaining impressions than water; while, if it is a solid, new impressions will either not be received at all, or only when the old impressions are effaced.

Passing from sensation to thought, it is admitted that abstract conceptions are incorporeal: how, then, can they be received and entertained by a corporeal substance? Or what possible connexion can there be between different arrangements of material particles and such notions as temperance and justice? This is already a sufficiently near approach to the language of modern philosophy. In another essay, which according to the original arrangement stands third, and must have been composed immediately after that whence the foregoing arguments are transcribed, there is more than an approach, there is complete coincidence.437 To deduce mind from atoms is, says Plotinus, if we may so speak, still more impossible than to deduce it from the elementary bodies. Granting that the atoms have a natural movement downwards, granting that they suffer a lateral deflection and so impinge on one another, still this could do no more than produce a disturbance in the bodies against which they strike. But to what atomic movement can one attribute psychic energies and affections? What sort of collision in the vertical line of descent, or in the oblique line of deflection, or in any direction you please, will account for the appearance of a particular kind of reasoning or mental impulse or thought, or how can it account for the existence of such processes at all? Here, of course, Plotinus is alluding to the Epicureans; but it is with the Stoic and other schools that he is principally concerned, and we return to his attack on their psychology.

The activities of the soul are thought, sensation, reasoning, desire, attention, and so forth: the activities of body are heat, cold, impact, and gravitation; if to these we add the characteristics of mind, the latter will have no special properties by which it can be known. And even in body we distinguish between quantity and quality; the former, at most, being corporeal, and the latter not corporeal at all. Here Plotinus just touches the idealistic method of modern spiritualism, but fails to follow it any further. He seems to have adopted Aristotle’s natural realism as a sufficient theory of external perception, and to have remained uninfluenced by Plato’s distrust of sensible appearances.

After disposing of the Stoic materialism, according to which the soul, though distinct from the body, is, equally with it, an extended and resisting substance, our philosopher proceeds to discuss the theories which make it a property or function of the body. The Pythagorean notion of the soul as a harmony of the body is met by a reproduction of the well-known arguments used against it in Plato’s Phaedo. Then comes the Aristotelian doctrine that the soul is the entelechy—that is to say, the realised purpose and perfection—of the physical organism to which it belongs. This is an idea which Aristotle himself had failed to make very clear, and the inadequacy of which he had virtually acknowledged by ascribing a different origin to reason, although this is counted as one of the psychic faculties. Plotinus, at any rate, could not appreciate an explanation which, whatever else it implied, certainly involved a considerable departure from his own dualistic interpretation of the difference between spirit and matter. He could not enter into Aristotle’s view of the one as a lower and less concentrated form of the other. The same arguments which had already been employed against Stoicism are now turned against the Peripatetic psychology. The soul as a principle, not only of memory and desire, but even of nutrition, is declared to be independent of and separable from the body. And, finally, as a result of the whole controversy, its immortality is affirmed. But how far this immortality involves the belief in a prolongation of personal existence after death, is a point which still remains uncertain. We shall return to the question in dealing with the religious opinions of Plotinus.

Closely connected with the materialism of the Stoics, and equally adverse to the principles of Plato and Aristotle, was their fatalism. In opposition to this, Plotinus proceeds to develop the spiritualistic doctrine of free-will.438 In the previous discussion, we had to notice how closely his arguments resemble those employed by more modern controversialists. We have here to point out no less wide a difference between the two. Instead of presenting free-will as a fact of consciousness which is itself irreconcilable with the dependence of mental on material changes, our philosopher, conversely, infers that the soul must be free both from the conditions of mechanical causation and from the general interdependence of natural forces, because it is an individual substance.439 In truth, the phenomena of volition were handled by the ancient philosophers with a vagueness and a feebleness offering the most singular contrast to their powerful and discriminating grasp of other psychological problems. Of necessarianism, in the modern sense, they had no idea. Aristotle failed to see that, quite apart from external restraints, our choice may conceivably be determined with the utmost rigour by an internal motive; nor could he understand that the circumstances which make a man responsible for his actions do not amount to a release of his conduct from the law of universal causation. In this respect, Plato saw somewhat deeper than his disciple, but created fresh confusion by identifying freedom with the supremacy of reason over irrational desire.440 Plotinus generally adopts the Platonist point of view. According to this, the soul is free when she is extricated from the bonds of matter, and determined solely by the conditions of her spiritual existence. Thus virtue is not so much free as identical with freedom; while, contrariwise, vice means enslavement to the affections of the body, and therefore comes under the domain of material causation.441 Yet, again, in criticising the fatalistic theories which represent human actions as entirely predetermined by divine providence, he protests against the ascription of so much that is evil to so good a source, and insists that at least the bad actions of men are due to their own free choice.442

In vindicating human freedom, Plotinus had to encounter a difficulty exceedingly characteristic of his age. This was the astrological superstition that everything depended on the stars, and that the future fate of every person might be predicted by observing their movements and configurations at the time of his birth. Philosophers found it much easier to demolish the pretensions of astrology by an abstract demonstration of their absurdity, than to get rid of the supposed facts which were currently quoted in their favour. That fortunes could be foretold on the strength of astronomical calculations with as much certainty as eclipses, seems to have been an accepted article of belief in the time of Plotinus, and one which he does not venture to dispute. He is therefore obliged to satisfy himself with maintaining that the stars do not cause, but merely foreshow the future, in the same manner as the flight of birds, to the prophetic virtue of which he also attaches implicit credence. All parts of Nature are connected by such an intimate sympathy, that each serves as a clue to the rest; and, on this principle, the stars may be regarded as the letters of a scripture in which the secrets of futurity are revealed.443

How much originality there may be in the anti-materialistic arguments of Plotinus we cannot tell. He certainly marks a great advance on Plato and Aristotle, approximating, in this respect, much more closely than they do to the modern standpoint. The indivisibility and permanence of mind had, no doubt, been strongly insisted on by those teachers, in contrast with the extended and fluctuating nature of body. But they did not, like him, deduce these characteristics from a direct analysis of consciousness as such. Plato inferred the simplicity and self-identity of mind from the simplicity and self-identity of the ideas which it contemplates. Aristotle went a step further, or perhaps only expressed the same meaning more clearly, when he associated immateriality with the identity of subject and object in thought.444 Moreover, both Plato and Aristotle seem to have rested the whole spiritualistic case on objective rather than on subjective considerations; although, as we have seen, the subjective interest was what dominated all the while in their thoughts. Starting with the analogy of a living body, Plato argues, both in the Phaedrus and in the Laws, that soul must everywhere be the first cause of motion, and therefore must exist prior to body.445 The elaborate scientific analysis of Aristotle’s Physics leads up to a similar conclusion; and the ontological analysis of the Metaphysics starts with the distinction between Form and Matter in bodies, to end with the question of their relative priority, and of the objective machinery by which they are united. Plotinus, too, sometimes refers to mind as the source of physical order; but this is rather in deference to his authorities than because the necessity of such an explanation seemed to him, as it did to them, the deepest ground of a spiritualistic philosophy. On the other hand, his psychological arguments for the immateriality of the soul are drawn from a wider area of experience than theirs, feeling being taken into account no less than thought; instead of restricting himself to one particular kind of cognition for evidence of spiritual power, he looks for it in every manifestation of living personality.

In criticising the Stoic system as a whole, the New Academy and the later Sceptics had incidentally dwelt on sundry absurdities which followed from the materialistic interpretation of knowledge; and Plotinus evidently derived some of his most forcible objections from their writings; but no previous philosopher that we know of had set forth the whole case for spiritualism and against materialism with such telling effect. And what is, perhaps, more important than any originality in detail, is the profound insight shown in choosing this whole question of spiritualism versus materialism for the ground whereon the combined forces of Plato and Aristotle were to fight their first battle against the naturalistic system which had triumphed over them five centuries before. It was on dialectical and ethical grounds that the controversy between Porch and Academy, on ethical and religious grounds that the controversy between Epicureanism and all other schools of philosophy, had hitherto been conducted. Cicero and Plutarch never allude to their opponents as materialists. Only once, in his polemic against Colôtes, does Plutarch observe that neither a soul nor anything else could be made out of atoms, but this is because they are discrete, not because they are extended.446 For the rest, his method is to trip up his opponents by pointing out their inconsistencies, rather than to cut the ground from under their feet by proving that their theory of the universe is wrong.

Under such guidance as this. Platonism had made but little way. We saw, in the concluding sections of the last chapter and in the opening section of the present chapter, that it profited by the religious and literary revival of the second century, just as it was to profit long afterwards by the greater revival of the fifteenth century, so much so as to become the fashionable philosophy of the age. Yet, even in that period of its renewed splendour, the noblest of contemporary thinkers was not a Platonist but a Stoic; and although it would be unfair to measure the moral distance between the Porch and the Academy by the interval which separates an Aurelius from an Apuleius, still it would seem as if naturalism continued to be the chosen creed of strenuous and dutiful endeavour, while spiritualism was drifting into an alliance with hysterical and sensuous superstition. If we may judge by the points which Sextus Empiricus selects for controversial treatment, Stoicism was still the reigning system in his time, that is to say, about the beginning of the third century; and if, a generation later, it had sunk into neglect, every rival school, except that of Epicurus, was in exactly the same condition. Thus the only advance made was to substitute one form of materialism for another, until Neo-Platonism came and put an end to their disputes by destroying the common foundation on which they stood; while, at the same time, it supplied a completely organised doctrine round which the nobler elements of the Hellenic revival could rally for a last stand against the foes that were threatening it from every side.
