Certainly in Italy, they hold it a little suspect in popes, when they have often in their mouth Padre commune: and take it to be a sign of one, that meaneth to refer all to the greatness of his own house. Kings had need beware, how they side themselves, and make themselves as of a faction or party; for leagues within the state, are ever pernicious to monarchies: for they raise an obligation, paramount to obligation of sovereignty, and make the king tanquam unus ex nobis; as was to be seen in the League of France. When factions are carried too high and too violently, it is a sign of weakness in princes; and much to the prejudice, both of their authority and business. The motions of factions under kings ought to be, like the motions (as the astronomers speak) of the inferior orbs, which may have their proper motions, but yet still are quietly carried, by the higher motion of primum mobile.
