  Hume famously criticizes the social contract theory of political obligation. According to his own theory, our duty to obey our governors is not reducible to an instance of our duty to fulfill promises, but arises separately though in a way parallel to the genesis of that duty.  Hume denies that any native citizen or subject in his own day has made even a tacit promise to obey the government, given that citizens do not think they did any such thing, but rather think they are born to obey it. Even a tacit contract requires that the will be engaged, and we have no memory of this; nor do governments refrain from punishing disloyalty in citizens who have given no tacit promise.
