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.
