Weighing all which circumstances, we see that to have kept Rome in the same tranquility wherein these republics were kept, one of two courses must have been followed by her legislators; for either, like the Venetians, they must have refrained from employing the commons in war, or else, like the Spartans, they must have closed their country to foreigners. Whereas, in both particulars, they did the opposite, arming the commons and increasing their number, and thus affording endless occasions for disorder. And had the Roman commonwealth grown to be more tranquil, this inconvenience would have resulted, that it must at the same time have grown weaker, since the road would have been closed to that greatness to which it came, for in removing the causes of her tumults, Rome must have interfered with the causes of her growth.
And he who looks carefully into the matter will find, that in all human affairs, we cannot rid ourselves of one inconvenience without running into another. So that if you would have your people numerous and warlike, to the end that with their aid you may establish a great empire, you will have them of such a sort as you cannot afterwards control at your pleasure; while should you keep them few and unwarlike, to the end that you may govern them easily, you will be unable, should you extend your dominions, to preserve them, and will become so contemptible as to be the prey of any who attack you. For which reason in all our deliberations we ought to consider where we are likely to encounter least inconvenience, and accept that as the course to be preferred, since we shall never find any line of action entirely free from disadvantage.
Rome might, therefore, following the example of Sparta, have created a king for life and a senate of limited numbers, but desiring to become a great empire, she could not, like Sparta, have restricted the number of her citizens. So that to have created a king for life and a limited senate had been of little service to her.
Were any one, therefore, about to found a wholly new republic, he would have to consider whether he desired it to increase as Rome did in territory and dominion, or to continue within narrow limits. In the former case he would have to shape its constitution as nearly as possible on the pattern of the Roman, leaving room for dissensions and popular tumults, for without a great and warlike population no republic can ever increase, or increasing maintain itself.
