We have not far to seek for the cause of this fatal condemnation. Neo-Platonism is nothing if not a system, and as a system it is false, and not only false but out of relation to every accepted belief. In combining the dialectic of Plato with the metaphysics of Aristotle and the physics of Stoicism, Plotinus has contrived to rob each of whatever plausibility it once possessed. The Platonic doctrine of Ideas was an attempt to express something very real and important, the distinction between laws and facts in Nature, between general principles and particular observations in science, between ethical standards and everyday practice in life. The eternal Nous of Aristotle represented the upward struggle of Nature through mechanical, chemical, and vital movements to self-conscious thought. The world-soul of Stoicism represented a return to monism, a protest against the unphilosophical antithesis between God and the world, spirit and matter, necessity and free-will. Plotinus attempts to rationalise the Ideas by shutting them up in the Aristotelian Nous, with the effect of severing them still more hopelessly from the real world, and, at the same time, making their subjective origin still more flagrantly apparent than before. And along with the Stoic conception of a world-soul, he preserves all those superstitious fancies about secret spiritual sympathies and affinities connecting the different parts of Nature with one another which the conception of a transcendent Nous, as originally understood by Aristotle, had at least the merit of excluding. Finally, by a tremendous wrench of abstraction, the unity of existence is torn away from existence itself, and the most relative of all conceptions is put out of relation to the thought which, in the very same breath, it is declared to condition, and to the things which it is declared to create.
Again, on the practical side, by combining Plato with Aristotle and both with Stoicism, Plotinus contrives to eliminate what is most valuable in each. If, in the Republic, the Good was placed above all existence, this was only that we might transform existence into its image. If Aristotle placed the theoretical above the ethical virtues, he assigned no limits but those of observation and reasoning to the energising of theoretic power. If the Stoics rested morality on the absolute isolation of the human will, they deduced from this principle not only the inwardness of virtue, but also the individualisation of duty, the obligation of beneficence, and the forgiveness of sin. But with Plotinus, Reason has no true object of contemplation outside its own abstract ideas, and the self-realisation of Stoicism means a barren consciousness of personal identity, from which every variety of interest and sympathy is excluded: it is not an expansion of our own soul into coincidence with the absolute All, but a concentration of both into a single point, a flight of the alone to the alone;[503] and only in this utter solitude does he suppose that the Platonic Good is finally and wholly possessed.
Nor, with a single exception, is the fundamental untruth of the system redeemed by any just and original observations on points of detail such as lie so thickly scattered over the pages of other metaphysicians, both in ancient and modern literature. The single exception is the refutation of materialism to which attention has been already directed. Apart from this, the Enneads do not contain one single felicitous or suggestive idea, nothing that can enlarge the horizon of our thoughts, nothing that can exalt the purpose of our lives.
If, however, we pass to the second point of view, and judge Neo-Platonism according to the requirements, not of truth or of usefulness, but of beauty, our first verdict of utter condemnation will be succeeded by a much more favourable opinion. Plotinus has used the materials inherited from his predecessors with unquestionable boldness and skill; and the constructive power exhibited in the general plan of his vast system is fully equalled by the close reasoning with which every detail is elaborated and fitted into its proper place. Nothing can be imagined more imposing than this wondrous procession of forms defiling from the unknown to the unknown—from the self-developing consciousness of Reason as it breaks and flames and multiplies into a whole universe of being and life and thought, ever returning, by the very law of their production, to the source whence they have sprung—onward and outward on the wings of the cosmic Soul, through this visible world, where they reappear as images of intellectual beauty in the eternal revolutions of the starry spheres above, in the everlasting reproduction of organic species below, in the loveliest thoughts and actions of the loveliest human souls—till the utmost limits of their propagation and dispersion have been reached, till the last faint rays of existence die out in the dark and void region that extends to infinity beyond. Nothing in the realm of abstractions can be more moving than this Odyssey of the human soul, wakened by visions of earthly loveliness to a consciousness of her true destiny, a remembrance of her lost and forgotten home; then abandoning these for the possession of a more spiritual beauty, ascending by the steps of dialectic to a contemplation of the archetypal Ideas that lie folded and mutually interpenetrated in the bosom of the eternal Reason where thought and being are but the double aspect of a single absolute reality; seeking farther and higher, beyond the limits of existence itself, for a still purer unity, and finding in the awful solitude of that supreme elevation that the central source of all things does not lie without but within, that only in returning to self-identity does she return to the One; or, again, descending to the last confines of light and life that she may prolong their radiation into the formless depths of matter, projecting on its darkness an image of the glory whose remembrance still attends her in her fall.
Still more impressive, if we consider the writings of Plotinus on their personal side, and as a revelation of their author’s mind, is the high and sustained purity, the absolute detachment and disinterestedness by which they are characterised throughout. No trace of angry passion, no dallying with images of evil, interferes to mar their exalted spirituality from first to last. While the western world was passing through a period of horror and degradation such as had never been known before, the philosopher took refuge in an ideal sphere, and looked down on it all with no more disturbance to his serenity than if he had been the spectator of a mimic performance on the stage.[504] This, indeed, is one of the reasons why the Enneads are so much less interesting, from a literary point of view, than the works of the Roman Stoics. It is not only that we fail to find in them any allusions even of the faintest kind to contemporary events or to contemporary life and manners, such as abound in Seneca and Epictêtus, but there is not the slightest reference to the existence of such a thing as the Roman empire at all. One or two political illustrations occur, but they are drawn from old Greek city life, and were probably suggested by Plato or Aristotle.[505] But this tremendous blank is so perfectly in keeping with the whole spirit of Neo-Platonism as to heighten instead of lowering its aesthetic effect. In studying the philosophy of the preceding centuries, to whatever school it may belong, we have the image of death always before our eyes; and to fortify us against its terrors, we are continually called upon to remember the vanity of life. This is the protest of thought against the world, just as in Lucian and Sextus we hear the protest of the world against thought. At last the whole bitter strife comes to an end, the vision of sense passes away,
And leaves us with Plotinus and pure souls.
Here we need no deliverance from troubles and indignities which are not felt; nor do we need to be prepared for death, knowing that we can never die. The world will no longer look askance at us, for we have ceased to concern ourselves about its reformation. No scepticism can shake our convictions, for we have discovered the secret of all knowledge through the consciousness of that which is eternal in ourselves. Thus the world of outward experience has dropped out of our thoughts, because thought has orbed into a world of its own.

In the foregoing remarks we have already passed from the purely aesthetic to the historical or psychological view of Neo-Platonism—that is, the view which considers a philosophy in reference to the circumstances of its origin. Every speculative system reflects, more or less fully, the spirit of the age in which it was born; and the absence of all allusion to contemporary events does not prove that the system of Plotinus was an exception to this rule. It only proves that the tendency of the age was to carry away men’s thoughts from practical to theoretical interests. We have already characterised the first centuries of Roman imperialism as a period of ever-increasing religious reaction; and in this reaction we attempted to distinguish between the development of supernaturalist beliefs which were native to Greece and Italy, and the importation of beliefs which had originated in the East. We saw also how philosophy shared in the general tendency, how it became theological and spiritualistic instead of ethical and naturalistic, how its professors were converted from opponents into upholders of the popular belief. Now, according to some critics, Neo-Platonism marks another stage in the gradual substitution of faith for reason, of authority for independent thought; the only question being whether we should interpret it as a product of Oriental mysticism, or as a simple sequence of the same movement which had previously led from Cicero to Seneca, from Seneca to Epictêtus, from Epictêtus to Marcus Aurelius.
Of these views, the first is taken by Ritter, and adopted with some modifications by M. Vacherot in his Histoire de l’École d’Alexandrie. It is also unreservedly accepted by Donaldson in his continuation of Müller’s History of Greek Literature, and is probably held at this moment by most Englishmen who take any interest in the subject at all. The second view—according to which Neo-Platonism is, at least in its main features, a characteristic although degenerate product of Greek thought—is that maintained by Zeller. As against the Orientalising theory, it seems to us that Zeller has thoroughly proved his case.[506] It may be doubted whether there is a single idea in Plotinus which can be shown to have its exact counterpart in any of the Hindoo or other Asiatic systems whence he is supposed to have drawn; and, as our own analysis has abundantly shown, he says nothing that cannot be derived, either directly or by a simple and easy process of evolution, from Plato, Aristotle, and the Stoics. On the other hand, has not Zeller gone much too far in treating Neo-Platonism as a product of the great religious reaction which unquestionably preceded and accompanied its appearance? Has he not altogether underrated its importance as a purely speculative system, an effort towards the attainment of absolute truth by the simple exercise of human reason? It seems to us that he has, and we shall offer some grounds for venturing to differ from his opinion.
