Journal of Politics
Aristotle describes the polis as a self-sufficient compound. Its regime, he says, is responsible for shaping the whole character of the city' s people. But rarely is the city unified in its parts, and the formative power of the regime is not always this extensive. There are in fact three kinds of cities depicted in the Politics. They differ by the degree of partnership tying city members together. Accordingly, the problem of faction and its cure differs for each: for some cities, where the regime is unitary, the cure is consent; for others, with mixed regimes, it is participation; but for the ideal city it is homogeneity.
