But returning to the point first raised, I believe it necessary for us to follow the method of the Romans and not that of the other republics, for I know of no middle way.  We must, consequently, put up with those dissensions which arise between commons and senate, looking on them as evils which cannot be escaped if we would arrive at the greatness of Rome.

In connection with the arguments here used to prove that the authority of the tribunes was essential in Rome to the guardianship of freedom, we may naturally go on to show what advantages result to a republic from the power of impeachment; which, together with others, was conferred upon the tribunes; a subject to be noticed in the following Chapter.

CHAPTER VII.—­That to preserve Liberty in a State there must exist the Right to accuse.

To those set forward in a commonwealth as guardians of public freedom, no more useful or necessary authority can be given than the power to accuse, either before the people, or before some council or tribunal, those citizens who in any way have offended against the liberty of their country.

A law of this kind has two effects most beneficial to a State:  first, that the citizens from fear of being accused, do not engage in attempts hurtful to the State, or doing so, are put down at once and without respect of persons:  and next, that a vent is given for the escape of all those evil humours which, from whatever cause, gather in cities against particular citizens; for unless an outlet be duly provided for these by the laws, they flow into irregular channels and overwhelm the State.  There is nothing, therefore, which contributes so much to the stability and permanence of a State, as to take care that the fermentation of these disturbing humours be supplied by operation of law with a recognized outlet.  This might be shown by many examples, but by none so clearly as by that of Coriolanus related by Livius, where he tells us, that at a time when the Roman nobles were angry with the plebeians (thinking that the appointment of tribunes for their protection had made them too powerful), it happened that Rome was visited by a grievous famine, to meet which the senate sent to Sicily for corn.  But Coriolanus, hating the commons, sought to persuade the senate that now was the time to punish them, and to deprive them of the authority which they had usurped to the prejudice of the nobles, by withholding the distribution of corn, and so suffering them to perish of hunger.  Which advice of his coming to the ears of the people, kindled them to such fury against him, that they would have slain him as he left the Senate House, had not the tribunes cited him to appear and answer before them to a formal charge.
