All virtue, with Plotinus, rests on the superiority of the soul to the body. So far, he follows the common doctrine of Plato and Aristotle. But in working out the distinction, he is influenced by the individualising and theoretic philosophy of the latter rather than by the social and practical philosophy of the former. Or, again, we may say that with him the intellectualism of Aristotle is heightened and warmed by the religious aspirations of Plato, strengthened and purified by the Stoic passionlessness, the Stoic independence of external goods. In his ethical system, the virtues are arranged in an ascending scale. Each grade reproduces the old quadripartite division into Wisdom, Courage, Temperance and Justice, but in each their respective significance receives a new interpretation. As civic virtues, they continue to bear the meaning assigned to them in Plato’s Republic. Wisdom belongs to reason, Courage to passionate spirit, Temperance to desire, while Justice implies the fulfilment of its appropriate function by each.[493] But all this only amounts to the restriction of what would otherwise be unregulated impulse, the imposition of Form on Matter, the supremacy of the soul over the body; whereas what we want is to get rid of matter altogether. Here also, Plato sets us on the right track when he calls the virtues purifications. From this point of view, for the soul to energise alone without any interference, is Wisdom; not to be moved by the passions of the body is Temperance; not to dread separation from the body is Courage; and to obey the guidance of reason is Justice.[494] Such a disposition of the soul is what Plato means by flying from the world and becoming like God. Is this enough? No, it is not. We have, so far, been dealing only with the negative conditions of good, not with good itself. The essential thing is not purification, but what remains behind when the work of purification is accomplished. So we come to the third and highest grade of virtue, the truly divine life, which is a complete conversion to reason. Our philosopher endeavours to fit this also into the framework of the cardinal virtues, but not without imposing a serious strain on the ordinary meaning of words. Of Wisdom nothing need be said, for it is the same as rationality. Justice is the self-possession of mind, Temperance the inward direction towards reason, Courage the impassivity arising from resemblance to that which is by nature impassive.[495]
Plotinus is careful to make us understand that his morality has neither an ascetic nor a suicidal tendency. Pleasures are to be tolerated under the form of a necessary relief and relaxation; pains are to be removed, but if incurable, they are to be patiently borne; anger is, if possible, to be suppressed, and, at any rate, not allowed to exceed the limits of an involuntary movement; fear will not be felt except as a salutary warning. The bodily appetites will be restricted to natural wants, and will not be felt by the soul, except, perhaps, as a transient excitement of the imagination.[496] Whatever abstinences our philosopher may have practised on his own account, we find no trace of a tendency towards self-mortification in his writings, nothing that is not consistent with the healthiest traditions of Greek spiritualism as originally constituted by the great Athenian school.
While not absolutely condemning suicide, Plotinus restricts the right of leaving this world within much narrower limits than were assigned to it by the Stoics. In violently separating herself from the body, the soul, he tells us, is acting under the influence of some evil passion, and he intimates that the mischievous effects of this passion will prolong themselves into the new life on which she is destined to enter.[497] Translated into more abstract language, his meaning probably is that the feelings which ordinarily prompt to suicide, are such as would not exist in a well-regulated mind. It is remarkable that Schopenhauer, whose views of life were, on other points, the very reverse of those held by Plotinus, should have used very much the same argument against self-destruction. According to his theory, the will to life, which it should be our principal business to conquer, asserts itself strongly in the wish to escape from suffering, and only delays the final moment of peaceful extinction by rushing from one phase of existence to another. And in order to prove the possibility of such a revival, Schopenhauer was obliged to graft on his philosophy a theory of metempsychosis, which, but for this necessity, would certainly never have found a place in it at all. In this, as in many other instances, an ethical doctrine is apparently deduced from a metaphysical doctrine which has, in reality, been manufactured for its support. All systems do but present under different formulas a common fund of social sentiment. A constantly growing body of public opinion teaches us that we do not belong to ourselves, but to those about us, and that, in ordinary circumstances, it is no less weak and selfish to run away from life than to run away from death.
Plotinus follows up his essay on the Virtues by an essay on Dialectic.[498] As a method for attaining perfection, he places dialectic above ethics; and, granting that the apprehension of abstract ideas ranks higher than the performance of social duties, he is quite consistent in so doing. Not much, however, can be made of his few remarks on the subject. They seem to be partly meant for a protest against the Stoic idea that logic is an instrument for acquiring truth rather than truth itself, and also against the Stoic use or abuse of the syllogistic method. In modern phraseology, Plotinus seems to view dialectic as the immanent and eternal process of life itself, rather than as a collection of rules for drawing correct inferences from true propositions, or from propositions assumed to be true. We have seen how he regarded existence in the highest sense as identical with the self-thinking of the absolute Nous, and how he attempted to evolve the whole series of archetypal Ideas contained therein from the simple fact of self-consciousness. Thus he would naturally identify dialectic with the subjective reproduction of this objective evolution; and here he would always have before his eyes the splendid programme sketched in Plato’s Republic.[499] His preference of intuitive to discursive reasoning has been quoted by Ritter as a symptom of mysticism. But here, as in so many instances, he follows Aristotle, who also held that simple abstraction is a higher operation, and represents a higher order of real existence than complex ratiocination.[500]
The ultimate stage of perfection is, of course, the identification of subject and object, the ascent from the Nous to the One. But, on this point, Plotinus never added anything essential to what has already been quoted from the analytical portion of his enquiry, and the essay containing that passage is accordingly placed last in Porphyry’s arrangement of his works.
Our account of Neo-Platonism has, with the exception of a few illustrations, been derived exclusively from the earlier essays of Plotinus. His subsequent writings are exceedingly obscure and tedious, and they add little by way either of development or defence to the outlines which he had sketched with a master’s hand. Whatever materials they may supply for a better appreciation, whether of his philosophy or of his general character as a thinker, will most profitably find their place in the final survey of both which we shall now attempt to give.
IX.
Every great system of philosophy may be considered from four distinct points of view. We may ask what is its value as a theory of the world and of human life, measured either by the number of new truths which it contains, or by the stimulus to new thought which it affords. Or we may consider it from the aesthetic side, as a monumental structure interesting us not by its utility, but by its beauty and grandeur. Under this aspect, a system may be admirable for its completeness, coherence, and symmetry, or for the great intellectual qualities exhibited by its architect, although it may be open to fatal objections as a habitation for human beings, and may fail to reproduce the plan on which we now know that the universe is built. Or, again, our interest in the work may be purely historical and psychological; we may look on it as the product of a particular age and a particular mind, as summing up for us under their most abstract form the ideas and aspirations which at any given moment had gained possession of educated opinion. Or, finally, we may study it as a link in the evolution of thought, as a result of earlier tendencies, and an antecedent of later developments. We propose to make a few remarks on the philosophy of Plotinus, or, what is the same thing, on Neo-Platonism in general, from each of these four points of view.
In absolute value, Neo-Platonism stands lowest as well as last among the ancient schools of thought. No reader who has followed us thus far will need to be reminded how many valuable ideas were first brought to light, or reinforced with new arguments and illustrations by the early Greek thinkers, by the Sophists and Socrates, by Plato and Aristotle, by the Stoics, Epicureans, and Sceptics, and by the moralists of the Roman empire. On every subject of speculation that can be started, we continue to ask, like Plotinus himself, what the ‘blessed ancients’ had to say about it;[501] not, of course, because they lived a long time ago, but because they came first, because they said what they had to say with the unique charm of original discovery, because they were in more direct contact than we are, not, indeed, with the facts, but with the phenomena of Nature and life and thought. It is true that we have nothing more to learn from them, for whatever was sound in their teaching has been entirely absorbed into modern thought, and combined with ideas of which they did not dream. But until we come to Hume and his successors, there is nothing in philosophical literature that can be compared to their writings for emancipating and stimulating power; and, perhaps, when the thinkers of the last and present centuries have become as obsolete as Bacon and Descartes are now, those writings will continue to be studied with unabating zeal. Neo-Platonism, on the other hand, is dead, and every attempt made to galvanise it into new life has proved a disastrous failure. The world, that is to say the world of culture, will not read Plotinus and his successors, will not even read the books that are written about them by scholars of brilliant literary ability like MM. Vacherot and Jules Simon in France, Steinhart and Kirchner in Germany.[502]
