Aristotle, in describing the requisites, which fit men for servitude, says, that "those men, whose powers are chiefly confined to the body, and whose principal excellence consists in affording bodily service, are naturally slaves, because it is their interest to be so." In the same manner some nations are of such a disposition that they are more calculated to obey than to govern, which seems to have been the opinion which the Cappadocians held of themselves, who when the Romans offered them a popular government, refused to accept it, because the nation they said could not exist in safety without a king. Thus Philostratus in the life of Apollonius, says, that it was foolish to offer liberty to the Thracians, the Mysians, and the Getae, which they were not capable of enjoying. The example of nations, who have for many ages lived happily under a kingly government, has induced many to give the preference to that form. Livy says, that the cities under Eumenes would not have changed their condition for that of any free state whatsoever. And sometimes a state is so situated, that it seems impossible it can preserve its peace and existence, without submitting to the absolute government of a single person, which many wise men thought to be the case with the Roman Republic in the time of Augustus Caesar. From these, and causes like these it not only may, but generally does happen, that men, as Cicero observes in the second book of his offices, willingly submit to the supreme authority of another.
