As we have said, this science has an especial reference to the occupations and requirements of statesmen, with whom also political and ethical philosophy is mainly concerned; and here is an evidence. We distinguish the different kinds of civil government by the office of their chief men, denominating one government a monarchy, or kingdom, another an aristocracy, a third a democracy; for so many we consider are the forms of government, and we designate them by these names, because from them they derive their primary characteristic. For the laws which emanate from the sovereign, from the aristocracy, and from the people all are different. The law is in fact a type of the form of government. It is on this account that some define right to be the interest of the strongest. If, therefore, political philosophy is advantageous to the ruler, and geography in the actual government of the country, this latter seems to possess some little superiority. This superiority is most observable in real service.
