aristocracies, oligarchies, or democracies, have a regard to (for in placing the supreme power they all think it right to fix it to excellence, though not the same); but it is also agreeable to what has been already said; as it would not be right to kill, or banish, or ostracise such a one for his superior merit. Nor would it be proper to let him have the supreme power only in turn; for it is contrary to nature that what is highest should ever be lowest: but this would be the case should such a one ever be governed by others. So that there can nothing else be done but to submit, and permit him continually to enjoy the supreme power. And thus much with respect to kingly power in different states, and whether it is or is not advantageous to them, and to what, and in what manner. CHAPTER XVIII Since then we have said that there are three sorts of regular governments, and of these the best must necessarily be that which is administered by the best men (and this must be that which happens to have one man, or one family, or a number of persons excelling all the rest in virtue, who are able to govern and be governed in such a manner as will make life most agreeable, and we have already shown that the virtue of a good man and of a citizen in the most perfect government will be the same), it is evident, that in the same manner, and for those very qualities which would procure a man the character of good, any one would say, that the government of a state was a well-established aristocracy or kingdom; so that it will be found to be education and [1288b] morals that are almost the whole which go to make a good man, and the same qualities will make a good citizen or good king. These particulars being treated of, we will now proceed to consider what sort of government is best, how it naturally arises, and how it is established; for it is necessary to make a proper inquiry concerning this.
