Now the supposed good or evil of any act, especially in political matters which admit of great variety of opinions and much discussion, is not a sufficient mark to ascertain these bounds. From whence the greatest confusion must follow, if under pretence of promoting good or averting evil measures, the people might struggle for the Prince's jurisdiction: a turbulent state of affairs, which no sober minded people ever wished to experience. X. After refuting false opinions, it remains to apply some cautions, which may point out the way to ascertain correctly the person to whom sovereign power, in every state, of right belongs. The first caution necessary is to avoid being deceived by ambiguous terms, or appearances foreign to the real subject. For instance, among the Latins, although the terms PRINCIPALITY and KINGDOM are generally opposed to each other, when Caesar says, that the father of Vercingetorix held the principality of Gaul, and was put to death for aiming at sovereign power; and when Piso, in Tacitus calls Germanicus the son of a Roman Prince, not of a Parthian King; and when Suetonius says, that Caligula was on the point of converting the power of a prince into that of a king; and Velleius asserts that Maroboduus not contented with the authority of a prince over voluntary adherents and dependents, was grasping in his mind at regal power; yet we find these terms though in reality very distinct were often confounded. For the Lacedaemonian chiefs, the descendants of Hercules, though subject to the controul of the Ephori, were nevertheless called kings: and Tacitus says, that among the ancient Germans there were kings, who governed more by the influence of persuasion than by the authority of power. Livy too, speaking of king Evander, describes him as reigning more by personal authority than by his regal power; and Aristotle, Polybius, and Diodorus give the names of Kings to the Suffetes or Judges of the Carthaginians. In the same manner Solinus also calls Hanno King of the Carthaginians. Strabo speaks of Scepsis in Troas, that having incorporated the Milesians into the state, it formed itself into a Democracy, leaving the descendants of the ancient kings the title, and something of the dignity of kings. On the other hand, the Roman emperors, after they had exercised openly, and without any disguise, a most absolute monarchical power, were notwithstanding called Princes. And in some popular states the chief magistrates are graced with ensigns of royalty.
