and sent them back Romans.”370
It is manifest how profound a change had taken place since the Republican days, when the highest dignities were long monopolised by a single class, when the censors repressed with a stringent severity every form or exhibition of luxury, when the rhetoricians were banished from the city, lest the faintest tinge of foreign manners should impair the stern simplicity of the people, and when the proposal to transfer the capital to Veii, after a great disaster, was rejected on the ground that it would be impious to worship the Roman deities anywhere but on the Capitol, or for the Flamens and the Vestals to emigrate beyond the walls.371
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, 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 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 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 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 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
