It followed that the sovereign people had a right to do whatever was within its power, and was bound by no rule of right or wrong but its own judgment of expediency. On a memorable occasion the assembled Athenians declared it monstrous that they should be prevented from doing whatever they chose. No force that existed could restrain them; and they resolved that no duty should restrain them, and that they would be bound by no laws that were not of their own making. In this way the emancipated people of Athens became a tyrant; and their Government, the pioneer of European freedom, stands condemned with a terrible unanimity by all the wisest of the ancients. They ruined their city by attempting to conduct war by debate in the marketplace. Like the French Republic, they put their unsuccessful commanders to death. They treated their dependencies with such injustice that they lost their maritime Empire. They plundered the rich until the rich conspired with the public enemy, and they crowned their guilt by the martyrdom of Socrates.
When the absolute sway of numbers had endured for near a quarter of a century, nothing but bare existence was left for the State to lose; and the Athenians, wearied and despondent, confessed the true cause of their ruin. They understood that for liberty, justice, and equal laws, it is as necessary that Democracy should restrain itself as it had been that it should restrain the Oligarchy. They resolved to take their stand once more upon the ancient ways, and to restore the order of things which had subsisted when the monopoly of power had been taken from the rich and had not been acquired by the poor. After a first restoration had failed, which is only memorable because Thucydides, whose judgment in politics is never at fault, pronounced it the best Government Athens had enjoyed, the attempt was renewed with more experience and greater singleness of purpose. The hostile parties were reconciled, and proclaimed an amnesty, the first in history. They resolved to govern by concurrence. The laws, which had the sanction of tradition, were reduced to a code; and no act of the sovereign assembly was valid with which they might be found to disagree. Between the sacred lines of the Constitution which were to remain inviolate, and the decrees which met from time to time the needs and notions of the day, a broad distinction was drawn; and the fabric of a law which had been the work of generations was made independent of momentary variations in the popular will. The repentance of the Athenians came too late to save the Republic. But the lesson of their experience endures for all times, for it teaches that government by the whole people, being the government of the most numerous and most powerful class, is an evil of the same nature as unmixed monarchy, and requires, for nearly the same reasons, institutions that shall protect it against itself, and shall uphold the permanent reign of law against arbitrary revolutions of opinion.
Parallel with the rise and fall of Athenian freedom, Rome was employed in working out the same problems, with greater constructive sense, and greater temporary success, but ending at last in a far more terrible catastrophe. That which among the ingenious Athenians had been a development carried forward by the spell of plausible argument, was in Rome a conflict between rival forces. Speculative politics had no attraction for the grim and practical genius of the Romans. They did not consider what would be the cleverest way of getting over a difficulty, but what way was indicated by analogous cases; and they assigned less influence to the impulse and spirit of the moment, than to precedent and example. Their peculiar character prompted them to ascribe the origin of their laws to early times, and in their desire to justify the continuity of their institutions, and to get rid of the reproach of innovation, they imagined the legendary history of the kings of Rome. The energy of their adherence to traditions made their progress slow, they advanced only under compulsion of almost unavoidable necessity, and the same questions recurred often, before they were settled. The constitutional history of the Republic turns on the endeavours of the aristocracy, who claimed to be the only true Romans, to retain in their hands the power they had wrested from the kings, and of the plebeians to get an equal share in it. And this controversy, which the eager and restless Athenians went through in one generation, lasted for more than two centuries, from a time when the plebs were excluded from the government of the city, and were taxed, and made to serve without pay, until, in the year 286, they were admitted to political equality. Then followed one hundred and fifty years of unexampled prosperity and glory; and then, out of the original conflict which had been compromised, if not theoretically settled, a new struggle arose which was without an issue.
The mass of poorer families, impoverished by incessant service in war, were reduced to dependence on an aristocracy of about two thousand wealthy men, who divided among themselves the immense domain of the State. When the need became intense the Gracchi tried to relieve it by inducing the richer classes to allot some share in the public lands to the common people. The old and famous aristocracy of birth and rank had made a stubborn resistance, but it knew the art of yielding. The later and more selfish aristocracy was unable to learn it. The character of the people was changed by the sterner motives of dispute. The fight for political power had been carried on with the moderation which is so honourable a quality of party contests in England. But the struggle for the objects of material existence grew to be as ferocious as civil controversies in France. Repulsed by the rich, after a struggle of twenty-two years, the people, three hundred and twenty thousand of whom depended on public rations for food, were ready to follow any man who promised to obtain for them by revolution what they could not obtain by law.
For a time the Senate, representing the ancient and threatened order of things, was strong enough to overcome every popular leader that arose, until Julius Cæsar, supported by an army which he had led in an unparalleled career of conquest, and by the famished masses which he won by his lavish liberality, and skilled beyond all other men in the art of governing, converted the Republic into a Monarchy by a series of measures that were neither violent nor injurious.
The Empire preserved the Republican forms until the reign of Diocletian; but the will of the Emperors was as uncontrolled as that of the people had been after the victory of the Tribunes. Their power was arbitrary even when it was most wisely employed, and yet the Roman Empire rendered greater services to the cause of liberty than the Roman Republic. I do not mean by reason of the temporary accident that there were emperors who made good use of their immense opportunities, such as Nerva, of whom Tacitus says that he combined monarchy and liberty, things otherwise incompatible; or that the Empire was what its panegyrists declared it, the perfection of Democracy. In truth it was at best an ill-disguised and odious despotism. But Frederic the Great was a despot; yet he was a friend to toleration and free discussion. The Bonapartes were despotic; yet no liberal ruler was ever more acceptable to the masses of the people than the First Napoleon, after he had destroyed the Republic, in 1805, and the Third Napoleon at the height of his power in 1859. In the same way, the Roman Empire possessed merits which, at a distance, and especially at a great distance of time, concern men more deeply than the tragic tyranny which was felt in the neighbourhood of the Palace. The poor had what they had demanded in vain of the Republic. The rich fared better than during the Triumvirate. The rights of Roman citizens were extended to the people of the provinces. To the imperial epoch belong the better part of Roman literature and nearly the entire Civil Law; and it was the Empire that mitigated slavery, instituted religious toleration, made a beginning of the law of nations, and created a perfect system of the law of property. The Republic which Cæsar overthrew had been anything but a free State. It provided admirable securities
