That was in fact the key factor driving the Constitutional Convention...while implementing a stronger central government, still preventing mob rule...
I like Wikipedia's distillation of Madison's view (which most Founders thought compelling) about faction and mob rule:
Federalist No. 10 continues the discussion of a question broached in Hamilton's Federalist No. 9. Hamilton had addressed the destructive role of faction in breaking apart a republic. The question Madison answers, then, is how to eliminate the negative effects of faction. He 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 saw direct democracy as a danger to individual rights and advocated a representative democracy (also called a republic), in order to protect individual liberty from majority rule. He says, "A pure democracy can admit no cure for the mischiefs of faction. A common passion or interest will be felt by a majority, and there is nothing to check the inducements to sacrifice the weaker party. Hence it is, that democracies have ever been found incompatible with personal security or the rights of property; and have, in general, been as short in their lives as they have been violent in their deaths."Like the anti-Federalists who opposed him, Madison was substantially influenced by the work of Montesquieu, though Madison and Montesquieu disagreed on the question addressed in this essay. He also relied heavily on the philosophers of the Scottish Enlightenment, especially David Hume, whose influence is most clear in Madison's discussion of the types of faction.
Thank you; that's a wonderful quote. I should get out my copy of the Federalist and actually read it.
I guess it's no coincidence that the Left pushes so hard for pure democracy.
