I can well believe, then, that to found a republic which shall long endure, the best plan may be to give it internal institutions like those of Sparta or Venice; placing it in a naturally strong situation, and so fortifying it that none can expect to get the better of it easily, yet, at the same time, not making it so great as to be formidable to its neighbours; since by taking these precautions, it might long enjoy its independence. For there are two causes which lead to wars being made against a republic; one, your desire to be its master, the other the fear lest it should master you; both of which dangers the precaution indicated will go far to remove. For if, as we are to assume, this republic be well prepared for defence, and consequently difficult of attack, it will seldom or never happen that anyone will form the design to attack it, and while it keeps within its own boundaries, and is seen from experience not to be influenced by ambition, no one will be led, out of fear for himself, to make war upon it, more particularly when its laws and constitution forbid its extension. And were it possible to maintain things in this equilibrium, I veritably believe that herein would be found the true form of political life, and the true tranquility of a republic. But all human affairs being in movement, and incapable of remaining as they are, they must either rise or fall; and to many conclusions to which we are not led by reason, we are brought by necessity. So that when we have given institutions to a state on the footing that it is to maintain itself without enlargement, should necessity require its enlargement, its foundations will be cut from below it, and its downfall quickly ensue. On the other hand, were a republic so favoured by Heaven as to lie under no necessity of making war, the result of this ease would be to make it effeminate and divided which two evils together, and each by itself, would insure its ruin. And since it is impossible, as I believe, to bring about an equilibrium, or to adhere strictly to the mean path, we must, in arranging our republic, consider what is the more honourable course for it to take, and so contrive that even if necessity compel its enlargement, it may be able to keep what it gains.
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.
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.
In respect of this incident I repeat what I have just now said, how useful and necessary it is for republics to provide by their laws a channel by which the displeasure of the multitude against a single citizen may find a vent. For when none such is regularly provided, recourse will be had to irregular channels, and these will assuredly lead to much worse results. For when
