It will now be better understood whence arose the hostility of the Stoics to pleasure, and how they could speak of it in what seems such a paradoxical style. It was subjective feeling as opposed to objective law; it was relative, particular, and individual, as opposed to their formal standard of right; and it was continually drawing men away from their true nature by acting as a temptation to vice. Thus, probably for the last reason, Cleanthes could speak of pleasure as contrary to Nature; while less rigorous authorities regarded it as absolutely indifferent, being a consequence of natural actions, not an essential element in their performance. And when their opponents pointed to the universal desire for pleasure as a proof that it was the natural end of animated beings, the Stoics answered that what Nature had in view was not pleasure at all, but the preservation of life itself.[48]

Such an interpretation of instinct introduces us to a new principle—self-interest; and this was, in fact, recognised on all hands as the foundation of right conduct; it was about the question, What is our interest? that the ancient moralists were disagreed. The Cynics apparently held that, for every being, simple existence is the only good, and therefore with them virtue meant limiting oneself to the bare necessaries of life; while by following Nature they meant reducing existence to its lowest terms, and assimilating our actions, so far as possible, to those of the lower animals, plants, or even stones, all of which require no more than to maintain the integrity of their proper nature.

Where the Cynics left off the Stoics began. Recognising simple self-preservation as the earliest interest and duty of man, they held that his ultimate and highest good was complete self-realisation, the development of that rational, social, and beneficent nature which distinguishes him from the lower animals.[49] Here their teleological religion came in as a valuable sanction for their ethics. Epictêtus, probably following older authorities, argues that self-love has purposely been made identical with sociability. ‘The nature of an animal is to do all things for its own sake. Accordingly God has so ordered the nature of the rational animal that it cannot obtain any particular good without at the same time contributing to the common good. Because it is self-seeking it is not therefore unsocial.’[50] But if our happiness depends on external goods, then we shall begin to fight with one another for their possession:[51] friends, father, country, the gods themselves, everything will, with good reason, be sacrificed to their attainment. And, regarding this as a self-evident absurdity, Epictêtus concludes that our happiness must consist solely in a righteous will, which we know to have been the doctrine of his whole school.

We have now reached the great point on which the Stoic ethics differed from that of Plato and Aristotle. The two latter, while upholding virtue as the highest good, allowed external advantages like pleasure and exemption from pain to enter into their definition of perfect happiness; nor did they demand the entire suppression of passion, but, on the contrary, assigned it to a certain part in the formation of character. We must add, although it was not a point insisted on by the ancient critics, that they did not bring out the socially beneficent character of virtue with anything like the distinctness of their successors. The Stoics, on the other hand, refused to admit that there was any good but a virtuous will, or that any useful purpose could be served by irrational feeling. If the passions agree with virtue they are superfluous, if they are opposed to it they are mischievous; and once we give them the rein they are more likely to disagree with than to obey it.[52] The severer school had more reason on their side than is commonly admitted. Either there is no such thing as duty at all, or duty must be paramount over every other motive—that is to say, a perfect man will discharge his obligations at the sacrifice of every personal advantage. There is no pleasure that he will not renounce, no pain that he will not endure, rather than leave them unfulfilled. But to assume this supremacy over his will, duty must be incommensurable with any other motive; if it is a good at all, it must be the only good. To identify virtue with happiness seems to us absurd, because we are accustomed to associate it exclusively with those dispositions which are the cause of happiness in others, or altruism; and happiness itself with pleasure or the absence of pain, which are states of feeling necessarily conceived as egoistic. But neither the Stoics nor any other ancient moralists recognised such a distinction. All agreed that public and private interest must somehow be identified; the only question being, should one be merged in the other, and if so, which? or should there be an illogical compromise between the two. The alternative chosen by Zeno was incomparably nobler than the method of Epicurus, while it was more consistent than the methods of Plato and Aristotle. He regarded right conduct exclusively in the light of those universal interests with which alone it is properly concerned; and if he appealed to the motives supplied by personal happiness, this was a confusion of phraseology rather than of thought.

The treatment of the passions by the Stoic school presents greater difficulties, due partly to their own vacillation, partly to the very indefinite nature of the feelings in question. It will be admitted that here also the claims of duty are supreme. To follow the promptings of fear or of anger, of pity or of love, without considering the ulterior consequences of our action, is, of course, wrong. For even if, in any particular instance, no harm comes of the concession, we cannot be sure that such will always be the case; and meanwhile the passion is strengthened by indulgence. And we have also to consider the bad effect produced on the character of those who, finding themselves the object of passion, learn to address themselves to it instead of to reason. Difficulties arise when we begin to consider how far education should aim at the systematic discouragement of strong emotion. Here the Stoics seem to have taken up a position not very consistent either with their appeals to Nature or with their teleological assumptions. Nothing strikes one as more unnatural than the complete absence of human feeling; and a believer in design might plausibly maintain that every emotion conduced to the preservation either of the individual or of the race. We find, however, that the Stoics, here as elsewhere reversing the Aristotelian method, would not admit the existence of a psychological distinction between reason and passion. According to their analysis, the emotions are so many different forms of judgment. Joy and sorrow are false opinions respecting good and evil in the present: desire and fear, false opinions respecting good and evil in the future.[53] But, granting a righteous will to be the only good, and its absence the only evil, there can be no room for any of these feelings in the mind of a truly virtuous man, since his opinions on the subject of good are correct, and its possession depends entirely on himself. Everything else arises from an external necessity, to strive with which would be useless because it is inevitable, foolish because it is beneficent, and impious because it is supremely wise.

It will be seen that the Stoics condemned passion not as the cause of immoral actions but as intrinsically vicious in itself. Hence their censure extended to the rapturous delight and passionate grief which seem entirely out of relation to conduct properly so called. This was equivalent to saying that the will has complete control over emotion; a doctrine which our philosophers did not shrink from maintaining. It might have been supposed that a position which the most extreme supporters of free-will would hardly accept, would find still less favour with an avowedly necessarian school. And to regard the emotions as either themselves beliefs, or as inevitably caused by beliefs, would seem to remove them even farther from the sphere of moral responsibility. The Stoics, however, having arrived at the perfectly true doctrine that judgment is a form of volition, seem to have immediately invested it as such with the old associations of free choice which they were at the same time busily engaged in stripping off from other exercises of the same faculty. They took up the Socratic paradox that virtue is knowledge; but they would not agree with Socrates that it could be instilled by force of argument. To them vice was not so much ignorance as the obstinate refusal to be convinced.[54]

The Stoic arguments are, indeed, when we come to analyse them, appeal to authority rather than to the logical understanding. We are told again and again that the common objects of desire and dread cannot really be good or evil, because they are not altogether under our control.[55] And if we ask why this necessarily excludes them from the class of things to be pursued or avoided, the answer is that man, having been created for perfect happiness, must also have been created with the power to secure it by his own unaided exertions. But, even granting the very doubtful thesis that there is any ascertainable purpose in creation at all, it is hard to see how the Stoics could have answered any one who chose to maintain that man is created for enjoyment; since, judging by experience, he has secured a larger share of it than of virtue, and is just as capable of gaining it by a mere exercise of volition. For the professors of the Porch fully admitted that their ideal sage had never been realised; which, with their opinions about the indivisibility of virtue, was equivalent to saying that there never had been such a thing as a good man at all. Or, putting the same paradox into other words, since the two classes of wise and foolish divide humanity between them, and since the former class has only an ideal existence, they were obliged to admit that mankind are not merely most of them fools, but all fools. And this, as Plutarch has pointed out in his very clever attack on Stoicism, is equivalent to saying that the scheme of creation is a complete failure.[56]

IV.

The inconsistencies of a great philosophical system are best explained by examining its historical antecedents. We have already attempted to disentangle the roots from which Stoicism was nourished, but one of the most important has not yet been taken into account. This was the still continued influence of Parmenides, derived, if not from his original teaching, then from some one or more of the altered shapes through which it had passed. It has been shown how Zeno used the Heracleitean method to break down all the demarcations laboriously built up by Plato and Aristotle. Spirit was identified with matter; ideas with aerial currents; God with the world; rational with sensible evidence; volition with judgment; and emotion with thought. But the idea of a fundamental antithesis, expelled from every other department of enquiry, took hold with all the more energy on what, to Stoicism, was the most vital of all distinctions—that between right and wrong.[57] Once grasp this transformation of a metaphysical into a moral principle, and every paradox of the system will be seen to follow from it with logical necessity. What the supreme Idea had been to Plato and self-thinking thought to Aristotle, that virtue became to the new school, simple, unchangeable, and self-sufficient. It must not only be independent of pleasure and pain, but absolutely incommensurable with them; therefore there can be no happiness except what it gives. As an indivisible unity, it must be possessed entirely or not at all; and being eternal, once possessed it can never be lost. Further, since the same action may be either right or wrong, according to the motive of its performance, virtue is nothing external, but a subjective disposition, a state of the will and the affections; or, if these are to be considered as judgments, a state of the reason. Finally, since the universe is organised reason, virtue must be natural, and especially consonant to the nature of man as a rational animal; while, at the same time, its existence in absolute purity being inconsistent with experience, it must remain an unattainable ideal.

It has been shown in former parts of this work how Greek philosophy, after straining an antithesis to the utmost, was driven by the very law of its being to close or bridge over the chasm by a series of accommodations and transitions. To this rule Stoicism was no exception; and perhaps its extraordinary vitality may have been partly due to the necessity imposed on its professors of continually revising their ethics, with a view to softening down its most repellent features. We proceed to sketch in rapid outline the chief artifices employed for this purpose.
