treme Democracy, is that in which all offices are open to all, and the will of the people overrides all law (c. 4). Of Oligarchies too there are four kinds; the worst is that in which offices are hereditary and the magistrates uncontrolled by law (c. 5). These variations arise under circumstances which may be briefly described (c. 6).

There are different ways of effecting the compromise which makes a Polity. The Laconian Constitution is an example of a successful compromise (c. 9).
