James Madison, channeling his inner Publius, takes on "factions" in The Federalist No. 10.
Among the numerous advantages promised by a well constructed union, none deserves to be more accurately developed, than its tendency to break and control the violence of faction. The friend of popular governments, never finds himself so much alarmed for their character and fate, as when he contemplates their propensity to this dangerous vice.
By a faction, I understand a number of citizens, whether amounting to a majority or minority of the whole, who are united and actuated by some common impulse of passion, or of interest, adverse to the rights of other citizens, or to the permanent and aggregate interests of the community.
Madison acknowledges that the causes of factionalism are deeply rooted in human nature, and are thus not open to removal. He then turns his attention to controlling the effects of factionalism. While not being a scholar on the subject, it would be my impression that he misjudged the problem.
The influence of factious leaders may kindle a flame within their particular states, but will be unable to spread a general conflagration through the other states: a religious sect may degenerate into a political faction in a part of the confederacy; but the variety of sects dispersed over the entire face of it, must secure the national councils against any danger from that source: a rage for paper money, for an abolition of debts, for an equal division of property, or for any other improper or wicked project, will be less apt to pervade the whole body of the union, than a particular member of it; in the same proportion as such a malady is more likely to taint a particular county or district, than an entire state.
