Madison first theorizes that there are two ways to limit the damage caused by faction: either remove the causes of faction or control its effects. He then describes the two methods to remove the causes of faction: first, destroying liberty, which would work because "liberty is to faction what air is to fire", but it is impossible to perform because liberty is essential to political life, just as air is "essential to animal life." After all, Americans fought for it during the American Revolution. The second option, creating a society homogeneous in opinions and interests, is impracticable. The diversity of the people's ability is what makes them succeed more or less, and inequality of property is a right that the government should protect. Madison particularly emphasizes that economic stratification prevents everyone from sharing the same opinion. Madison concludes that the damage caused by faction can be limited only by controlling its effects.
