“In estimating what amount of power would be requisite to secure the objects of government, we must take into the reckoning, what would be necessary to defend the community against external, as well as internal dangers. Government must be able to repel assaults from abroad, as well as to repress violence and disorders within. It must not be overlooked, that the human race is not comprehended in a single society or community. The limited reason and faculties of man, the great diversity of language, customs, pursuits, situation and complexion, and the difficulty of intercourse, with various other causes, have, by their operation, formed a great many separate communities, acting independently of each other. Between these there is the same tendency to conflict—and from the same constitution of our nature—as between men individually; and even stronger—because the sympathetic or social feelings are not so strong between different communities, as between individuals of the same community.”
