“ Democratic governments are less liable to revolutions than oligarchies, because oligarchs may fall out with each other. The oligarchs seem to have been vigorous fellows. ”

“Democracy, Aristotle says, arises from the belief that men who are equally free should be equal in all respects; oligarchy, from the fact that men who are superior in some respect claim too much. Both have a kind of justice, but not the best kind. “ Therefore both parties, whenever their share in the government does not accord with their preconceived ideas, stir up revolution ” (1301 ” ). Democratic governments are less liable to revolutions than oligarchies, because oligarchs may fall out with each other. The oligarchs seem to have been vigorous fellows. In some cities, we are told, they swore an oath: “ I will be an enemy to the people, and will devise all the harm against them which I can. ”
The three things needed to prevent revolution are government propaganda in education, respect for law, even in small things, and justice in law and administration, i.e., “ equality according to proportion, and for every man to enjoy his own ” (1307a, 1307b, 1310a).” source
