For on the first occasion, nothing more was needed to prepare and determine them to shake off their kings, than that they should be bound by oath to suffer no king ever again to reign in Rome; whereas, afterwards, the authority and austere virtue of Brutus, backed by all the legions of the East, could not rouse them to maintain their hold of that freedom, which he, following in the footsteps of the first Brutus, had won for them; and this because of the corruption wherewith the people had been infected by the Marian faction, whereof Caesar becoming head, was able so to blind the multitude that it saw not the yoke under which it was about to lay its neck.
Though this example of Rome be more complete than any other, I desire to instance likewise, to the same effect, certain peoples well known in our own days; and I maintain that no change, however grave or violent, could ever restore freedom to Naples or Milan, because in these States the entire body of the people has grown corrupted.

And so we find that Milan, although desirous to return to a free form of government, on the death of Filippo Visconti, had neither the force nor the skill needed to preserve it.
Most fortunate, therefore, was it for Rome that her kings grew corrupt soon, so as to be driven out before the taint of their corruption had reached the vitals of the city.

For it was because these were sound that the endless commotions which took place in Rome, so far from being hurtful, were, from their object being good, beneficial to the commonwealth.

From which we may draw this inference, that where the body of the people is still sound, tumults and other like disorders do little hurt, but that where it has become corrupted, laws, however well devised, are of no advantage, unless imposed by some one whose paramount authority causes them to be observed until the community be once more restored to a sound and healthy condition.
Whether this has ever happened I know not, nor whether it ever can happen.

For we see, as I have said a little way back, that a city which owing to its pervading corruption has once begun to decline, if it is to recover at all, must be saved not by the excellence of the people collectively, but of some one man then living among them, on whose death it at once relapses into its former plight; as happened with Thebes, in which the virtue of Epaminondas made it possible while he lived to preserve the form of a free Government, but which fell again on his death into its old disorders; the reason being that hardly any ruler lives so long as to have time to accustom to right methods a city which has long been accustomed to wrong.
