What's very cool is at the end of the passage, we see Harrington asserting "And as a commonwealth is a government of laws and not of men, ..."The third division (unseen hitherto) is into equal and unequal, and this is the main point especially as to domestic peace and tranquility. For to make a commonwealth unequal is to divide it into parties, which sets them at perpetual variance, the one party endeavoring to preserve their eminence and inequality, and the other to attain to equality. Whence the people of Rome derived their perpetual strife with the nobility or Senate. But in an equal commonwealth there can be no more strife than there can be overbalance in equal weights. Wherefore the commonwealth of Venice, being that which of all others is the most equal in the constitution, is that wherein there never happened any strife between the Senate and the people.An equal commonwealth is such a one as is equal, both in the balance and foundation and in the superstructures; that is to say, in her Agrarian Law and in her rotation.An equal Agrarian is a perpetual law establishing and preserving the balance of dominion by such a distribution that no one man or number of men within the compass of the few or aristocracy can come to overpower the whole people by their possessions in lands.As the Agrarian answers to the foundation, so does rotation to the superstructures.Equal rotation is equal vicissitude in government, or succession unto magistracy conferred for such convenient terms, enjoying equal vacations, as take in the whole body by parts succeeding others through the free election or suffrage of the people.
