Federalist No. 10 continues the discussion of the question broached in Hamilton's Federalist No. 9. Hamilton there addressed the destructive role of a faction in breaking apart the republic. The question Madison answers, then, is how to eliminate the negative effects of faction. Madison defines a faction as "a number of citizens, whether amounting to a minority or majority 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." He identifies the most serious source of faction to be the diversity of opinion in political life which leads to dispute over fundamental issues such as what regime or religion should be preferred.
