Aristotle: A Treatise on Government

BOOK IV 6. CHAPTER VI (continued)

The first species of oligarchy is, when the generality of the state are men of moderate and not too large property; for this gives them leisure for the management of public affairs: and, as they are a numerous body, it necessarily follows that the supreme power must be in the laws, and not in men; for as they are far removed from a monarchical government, and have not sufficient fortune to neglect their private affairs, while they are too many to be supported by the public, they will of course determine to be governed by the laws, and not by each other. But if the men of property in the state are but few, and their property is large, then an oligarchy of the second sort will take place; for those who have most power will think that they have a right to lord it over the others; and, to accomplish this, they will associate to themselves some who have an inclination for public affairs, and as they are not powerful enough to govern without law, they will make a law for that purpose. And if those few who have large fortunes should acquire still greater power, the oligarchy will then alter into one of the third sort; for they will get all the offices of the state into their own hands by a law which directs the son to succeed upon the death of his father; and, after that, when, by means of their increasing wealth and powerful connections, they extend still further their oppression, a monarchical dynasty will directly succeed wherein men will be supreme, and not the law; and this is the fourth species of an oligarchy correspondent to the last-mentioned class of democracies.
