"The continual attention of sovereigns to every occurrence, the constant residence of ministers, and the perpetual negotiations, make of modern Europe a kind of republic, of which the members—each independent, but all linked together by the ties of common interest—unite for the maintenance of order and liberty. Hence arose that famous scheme of the political balance, or the equilibrium of power; by which is understood such a disposition of things, as that no one potentate be able absolutely to predominate, and prescribe laws to the others."
