The greater number of these tendencies to universal fusion or equality were blind forces resulting from the stress of circumstances, and not from any human forethought, or were agencies that were put in motion for a different object. It must, however, be acknowledged that a definite theory of policy had a considerable part in accelerating the movement. The policy of the Republic may be broadly described as a policy of conquest, and that of the Empire as a policy of preservation. The Romans having acquired a vast dominion, were met by the great problem which every first-class power is called upon to solve—by what means many communities, [pg 238] with different languages, customs, characters, and traditions, can be retained peaceably under a single ruler. In modern times, this difficulty has been most successfully met by local legislatures, which, if they supply a “line of cleavage,” a nucleus around which the spirit of opposition may form, have on the other hand the priceless advantage of giving the annexed people a large measure of self-government, a centre and safety-valve of local public opinion, a sphere for local ambitions, and a hierarchy of institutions adapted to the distinctive national type. Under no other conditions can a complex empire be carried on with so little strain, or effort, or humiliation, or its inevitable final dissolution be effected with so little danger or convulsion. But local legislatures, which are the especial glory of English statesmanship, belong exclusively to modern civilisation. The Roman method of conciliation was, first of all, the most ample toleration of the customs, religion, and municipal freedom of the conquered, and then their gradual admission to the privileges of the conqueror. By confiding to them in a great measure the defence of the empire, by throwing open to them the offices of State, and especially by according to them the right of Roman citizenship, which had been for centuries jealously restricted to the inhabitants of Rome, and was afterwards only conceded to Italy and Cisalpine Gaul, the emperors sought to attach them to their throne. The process was very gradual, but the whole movement of political emancipation attained its completion when the Imperial throne was occupied by the Spaniard Trajan, and by Pertinax, the son of a freedman, and when an edict of Caracalla extended the rights of Roman citizenship to all the provinces of the empire.

It will appear evident, from the foregoing sketch, that the period which elapsed between Panætius and Constantine exhibited an irresistible tendency to cosmopolitanism. The convergence, when we consider the number, force, and harmony of the influences that composed it, is indeed unexampled [pg 239] in history. The movement extended through all the fields of religious, philosophical, political, industrial, military, and domestic life. The character of the people was completely transformed, the landmarks of all its institutions were removed, the whole principle of its organisation was reversed. It would be impossible to find a more striking example of the manner in which events govern character, destroying old habits and associations, and thus altering that national type of excellence which is, for the most part, the expression or net moral result of the national institutions and circumstances. The effect of the movement was, no doubt, in many respects evil, and some of the best men, such as the elder Cato and Tacitus, opposed it, as leading to the demoralisation of the empire; but if it increased vice, it also gave a peculiar character to virtue. It was impossible that the conception of excellence, formed in a society where everything conspired to deepen class divisions and national jealousies and antipathies, should be retained unaltered in a period of universal intercourse and amalgamation. The moral expression of the first period is obviously to be found in the narrower military and patriotic virtues; that of the second period in enlarged philanthropy and sympathy.

The Stoical philosophy was admirably fitted to preside over this extension of sympathies. Although it proved itself in every age the chief school of patriots, it recognised also, from the very first, and in the most unequivocal manner, the fraternity of mankind. The Stoic taught that virtue alone is a good, and that all other things are indifferent; and from this position he inferred that birth, rank, country, or wealth are the mere accidents of life, and that virtue alone makes one man superior to another. He taught also that the Deity is an all-pervading Spirit, animating the universe, and revealed with especial clearness in the soul of man; and he concluded that all men are fellow-members of a single body, united by participation in the same Divine Spirit. These two doctrines [pg 240] formed part of the very first teaching of the Stoics, but it was the special glory of the Roman teachers, and an obvious result of the condition of affairs I have described, to have brought them into full relief. One of the most emphatic as well as one of the earliest extant assertions of the duty of “charity to the human race,”[372] occurs in the treatise of Cicero upon duties, which was avowedly based upon Stoicism. Writing at a period when the movement of amalgamation had for a generation been rapidly proceeding,[373] and adopting almost without restriction the ethics of the Stoics, Cicero maintained the doctrine of universal brotherhood as distinctly as it was afterwards maintained by the Christian Church. “This whole world,” he tells us, “is to be regarded as the common city of gods and men.”[374] “Men were born for the sake of men, that each should assist the others.”[375] “Nature ordains that a man should wish the good of every man, whoever he may be, for this very reason, that he is a man.”[376] “To reduce man to the duties of his own city and to disengage him from duties to the members of other cities, is to break the universal society of the human race.”[377] “Nature has inclined us to love men, and this is the foundation of the law.”[378] The same principles were reiterated with increasing emphasis by the later Stoics. Adopting the well-known line which Terence had translated from Menander, they maintained that man should deem nothing human foreign to his interest. Lucan expatiated with all the fervour of a Christian poet upon the time when “the human race will cast aside its weapons, and when all nations will learn to love.”[379] “The whole universe,” said [pg 241] Seneca, “which you see around you, comprising all things, both divine and human, is one. We are members of one great body. Nature has made us relatives when it begat us from the same materials and for the same destinies. She planted in us a mutual love, and fitted us for a social life.”[380] “What is a Roman knight, or freedman, or slave? These are but names springing from ambition or from injury.”[381] “I know that my country is the world, and my guardians are the gods.”[382] “You are a citizen,” said Epictetus, “and a part of the world.... The duty of a citizen is in nothing to consider his own interest distinct from that of others, as the hand or foot, if they possessed reason and understood the law of nature, would do and wish nothing that had not some relation to the rest of the body.”[383] “An Antonine,” said Marcus Aurelius, “my country is Rome; as a man, it is the world.”[384]

So far Stoicism appears fully equal to the moral requirements of the age. It would be impossible to recognise more cordially or to enforce more beautifully that doctrine of universal brotherhood for which the circumstances of the Roman Empire had made men ripe. Plato had said that no one is born for himself alone, but that he owes himself in part to his country, in part to his parents, and in part to his friends. The Roman Stoics, taking a wider survey, declared that man is born not for himself but for the whole world.[385] And their doctrine was perfectly consistent with the original principles of their school.

But while Stoicism was quite capable of representing the widening movement, it was not equally capable of representing the softening movement of civilisation. Its condemnation [pg 242] of the affections, and its stern, tense ideal, admirably fitted for the struggles of a simple military age, were unsuited for the mild manners and luxurious tastes of the age of the Antonines. A class of writers began to arise who, like the Stoics, believed virtue, rather than enjoyment, to be the supreme good, and who acknowledged that virtue consisted solely of the control which the enlightened will exercises over the desires, but who at the same time gave free scope to the benevolent affections and a more religious and mystical tone to the whole scheme of morals. Professing various speculative doctrines, and calling themselves by many names—eclectics, peripatetics, or Platonists—they agreed in forming or representing a moral character, less strong, less sublime, less capable of endurance and heroism, less conspicuous for energy of will, than that of the Stoics, but far more tender and attractive. The virtues of force began to recede, and the gentler virtues to advance, in the moral type. Insensibility to suffering was no longer professed; indomitable strength was no longer idolised, and it was felt that weakness and sorrow have their own appropriate virtues.[386] The works of these writers are full of delicate touches which nothing but strong and lively feelings could have suggested. We find this in the well-known letter of Pliny on the death of his slaves,[387] in the frequent protests against the ostentation of indifference with which the Stoics regarded the loss of their friends, in many instances of simple, artless pathos, which strike the finest chords of our nature. When Plutarch, after the death of his daughter, was writing a letter of consolation to his wife, [pg 243] we find him turning away from all the commonplaces of the Stoics as the recollection of one simple trait of his little child rushed upon his mind:—“She desired her nurse to press even her dolls to the breast. She was so loving that she wished everything that gave her pleasure to share in the best of what she had.”

Plutarch, whose fame as a biographer has, I think, unduly eclipsed his reputation as a moralist, may be justly regarded as the leader of this movement, and his moral writings may be profitably compared with those of Seneca, the most ample exponent of the sterner school. Seneca is not unfrequently self-conscious, theatrical, and overstrained. His precepts have something of the affected ring of a popular preacher. The imperfect fusion of his short sentences gives his style a disjointed and, so to speak, granulated character, which the Emperor Caligula happily expressed when he compared it to sand without cement; yet he often rises to a majesty of eloquence, a grandeur both of thought and of expression, that few moralists have ever rivalled. Plutarch, though far less sublime, is more sustained, equable, and uniformly pleasing. The Montaigne of antiquity, his genius coruscates playfully and gracefully around his subject; he delights in illustrations which are often singularly vivid and original, but which, by their excessive multiplication, appear sometimes rather the texture than the ornament of his discourse. A gentle, tender spirit, and a judgment equally free from paradox, exaggeration, and excessive subtilty, are the characteristics of all he wrote. Plutarch excels most in collecting motives of consolation; Seneca in forming characters that need no consolation. There is something of the woman in Plutarch; Seneca is all a man. The writings of the first resemble the strains of the flute, to which the ancients attributed the power of calming the passions and charming away the clouds of sorrow, and drawing men by a gentle suasion into the paths of virtue; the writings of the other are like the trumpet-blast, [pg 244] which kindles the soul with an heroic courage. The first is most fitted to console a mother sorrowing over her dead child, the second to nerve a brave man, without flinching and without illusion, to grapple with an inevitable fate.

The elaborate letters which Seneca has left us on distinctive tenets of the Stoical school, such as the equality of vices or the evil of the affections, have now little more than an historic interest; but the general tone of his writings gives them a permanent importance, for they reflect and foster a certain type of excellence which, since the extinction of Stoicism, has had no adequate expression in literature. The prevailing moral tone of Plutarch, on the other hand, being formed mainly on the prominence of the amiable virtues, has been eclipsed or transcended by the Christian writers, but his definite contributions to philosophy and morals are more important than those of Seneca. He has left us one of the best works on superstition, and one of the most ingenious works on Providence, we possess. He was probably the first writer who advocated very strongly humanity to animals on the broad ground of universal benevolence, as distinguished from the Pythagorean doctrine of transmigration, and he was also remarkable, beyond all his contemporaries, for his high sense of female excellence and of the sanctity of female love.

The Romans had at all times cared more for the practical tendency of a system of philosophy than for its logical or speculative consistency. One of the chief attractions of Stoicism, in their eyes, had been that its main object was not to build a system of opinion, but to propose a pattern of life,[388] and Stoicism itself was only adapted to the Roman character after it had been simplified by Panætius.[389] Although the system could never free itself altogether from that hardness which rendered it so unsuited for an advanced civilisation, it [pg 245] was profoundly modified by the later Stoics, who rarely scrupled to temper it by the admixture of new doctrines. Seneca himself was by no means an unmixed Stoic. If Epictetus was more nearly so, this was probably because the extreme hardship he underwent made him dwell more than his contemporaries upon the importance of fortitude and endurance. Marcus Aurelius was surrounded by the disciples of the most various schools, and his Stoicism was much tinctured by the milder and more religious spirit of Platonism. The Stoics, like all other men, felt the moral current of the time, though they yielded to it less readily than some others. In Thrasea, who occupied in his age a position analogous to that of Cato in an earlier period, we find little or nothing of the asperity and hardness of his great prototype. In the writings of the later Stoics, if we find the same elements as in those of their predecessors, these elements are at least combined in different proportions.

In the first place, Stoicism became more essentially religious. The Stoical character, like all others of a high order, had always been reverential; but its reverence differed widely from that of Christians. It was concentrated much less upon the Deity than upon virtue, and especially upon virtue as exhibited in great men. When Lucan, extolling his hero, boasted that “the gods favoured the conquering cause, but Cato the conquered,” or when Seneca described “the fortune of Sulla” as “the crime of the gods,” these sentences, which sound to modern ears grossly blasphemous, appear to have excited no murmur. We have already seen the audacious language with which the sage claimed an equality with the Divinity. On the other hand, the reverence for virtue apart from all conditions of success, and especially for men of the stamp of Cato, who through a strong moral conviction struggled bravely, though unsuccessfully, against force, genius, or circumstances, was perhaps more steady and more passionate than in any later age. The duty of absolute [pg 246] submission to Providence, as I have already shown, was continually inculcated, and the pantheistic notion of all virtue being a part or emanation of the Deity was often asserted, but man was still the centre of the Stoic's scheme, the ideal to which his reverence and devotion aspired. In later Stoicism this point of view was gradually changed. Without any formal abandonment of their pantheistic conceptions, the language of philosophers recognised with much greater clearness a distinct and personal Divinity. Every page of Epictetus and Marcus Aurelius is impregnated with the deepest religious feeling. “The first thing to learn,” said the former, “is that there is a God, that His knowledge pervades the whole universe, and that it extends not only to our acts but to our thoughts and feelings.... He who seeks to please the gods must labour as far as lies in him to resemble them. He must be faithful as God is faithful, free as He is free, beneficent as He is beneficent, magnanimous as He is magnanimous.”[390] “To have God for our maker and father and guardian, should not that emancipate us from all sadness and from all fear?”[391] “When you have shut your door and darkened your room, say not to yourself you are alone. God is in your room, and your attendant genius likewise. Think not that they need the light to see what you do.[392] What can I, an old man and a cripple, do but praise God? If I were a nightingale, I would discharge the office of a nightingale; if a swan, that of a swan. But I am a reasonable being; my mission is to praise God, and I fulfil it; nor shall I ever, as far as lies in me, shrink from my task, and I exhort you to join in the same song of praise.”[393]

The same religious character is exhibited, if possible, in a still greater degree in the “Meditations” of Marcus Aurelius; but in one respect the ethics of the emperor differ [pg 247] widely from those of the slave. In Epictetus we invariably find the strongest sense of the majesty of man. As the child of the Deity, as a being capable of attaining the most exalted virtue, he magnified him to the highest point, and never more so than in the very passage in which he exhorted his disciples to beware of haughtiness. The Jupiter Olympus of Phidias, he reminds them, exhibits no arrogance, but the unclouded serenity of perfect confidence and strength.[394] Marcus Aurelius, on the other hand, dwelt rather on the weakness than on the force of man, and his meditations breathe a spirit, if not of Christian humility, at least of the gentlest and most touching modesty. He was not, it is true, like some later saints, who habitually apply to themselves language of reprobation which would be exaggerated if applied to the murderer or the adulterer. He did not shrink from recognising human virtue as a reality, and thanking Providence for the degree in which he had attained it, but he continually reviewed with an unsparing severity the weaknesses of his character, he accepted and even solicited reproofs from every teacher of virtue, he made it his aim, in a position of supreme power, to check every emotion of arrogance and pride, and he set before him an ideal of excellence which awed and subdued his mind.
