Those States consequently stand surest and endure longest which, either by the operation of their institutions can renew themselves, or come to be renewed by accident apart from any design. Nothing, however, can be clearer than that unless thus renewed these bodies do not last. Now the way to renew them is, as I have said, to bring them back to their beginnings, since all beginnings of sects, commonwealths, or kingdoms must needs have in them a certain excellence, by virtue of which they gain their first reputation and make their first growth. But because in progress of time this excellence becomes corrupted, unless something be done to restore it to what it was at first, these bodies necessarily decay; for as the physicians tell us in speaking of the human body, “_Something or other is daily added which sooner or later will require treatment._”[10] [10] “Quod quotidie aggregatur aliquid quod quandoque indiget curatione.” As regards commonwealths, this return to the point of departure is brought about either by extrinsic accident or by intrinsic foresight. As to the first, we have seen how it was necessary that Rome should be taken by the Gauls, that being thus in a manner reborn, she might recover life and vigour, and resume the observances of religion and justice which she had suffered to grow rusted by neglect. This is well seen from those passages of Livius wherein he tells us that when the Roman army was ‘sent forth against the Gauls, and again when tribunes were created with consular authority, no religious rites whatever were celebrated, and wherein he further relates how the Romans not only failed to punish the three Fabii, who contrary to the law of nations had fought against the Gauls, but even clothed them with honour. For, from these instances, we may well infer that the rest of the wise ordinances instituted by Romulus, and the other prudent kings, had begun to be held of less account than they deserved, and less than was essential for the maintenance of good government. And therefore it was that Rome was visited by this calamity from without, to the end that all her ordinances might be reformed, and the people taught that it behoved them not only to maintain religion and justice, but also to esteem their worthy citizens, and to prize their virtues beyond any advantages of which they themselves might seem to have been deprived at their instance. And this, we find, was just the effect produced. For no sooner was the city retaken, than all the ordinances of the old religion were at once restored; the Fabii, who had fought in violation of the law of nations, were punished; and the worth and excellence of Camillus so fully recognized, that the senate and the whole people, laying all jealousies aside, once more committed to him the entire charge of public affairs.
