But when the people grew depraved, this became a very mischievous institution; for then it was only the powerful who proposed laws, and these not in the interest of public freedom but of their own authority; and because, through fear, none durst speak against the laws they proposed, the people were either deceived or forced into voting their own destruction.
In order, therefore, that Rome after she had become corrupted might still preserve her freedom, it was necessary that, as in the course of events she had made new laws, so likewise she should frame new institutions, since different institutions and ordinances are needed in a corrupt State from those which suit a State which is not corrupted; for where the matter is wholly dissimilar, the form cannot be similar.
But since old institutions must either be reformed all at once, as soon as they are seen to be no longer expedient, or else gradually, as the imperfection of each is recognized, I say that each of these two courses is all but impossible.

For to effect a gradual reform requires a sagacious man who can discern mischief while it is still remote and in the germ.

But it may well happen that no such person is found in a city; or that, if found, he is unable to persuade others of what he is himself persuaded.

For men used to live in one way are loath to leave it for another, especially when they are not brought face to face with the evil against which they should guard, and only have it indicated to them by conjecture.

And as for a sudden reform of institutions which are seen by all to be no longer good, I say that defects which are easily discerned are not easily corrected, because for their correction it is not enough to use ordinary means, these being in themselves insufficient; but recourse must be had to extraordinary means, such as violence and arms; and, as a preliminary, you must become prince of the city, and be able to deal with it at your pleasure.
