Owing to this men who are exceptional in virtue generally speaking do not cause faction, because they find themselves few against many. Universally then in connection with all the forms of constitution the origins and causes of factions and revolutions are of this nature.

The means used to cause revolutions of constitutions are sometimes force and sometimes fraud. Force is employed either when the revolutionary leaders exert compulsion immediately from the start or later on—as indeed the mode of using fraud is also twofold: sometimes the revolutionaries after completely deceiving the people at the first stage alter the constitution with their consent, but then at a later stage retain their hold on it by force against the people’s will: for instance, at the time of the Four Hundred,The oligarchy at Athens 411 B.C., cf. 1305a 27. they deceived the people by saying that the Persian King would supply money for the war against the Spartans, and after telling them this falsehood endeavored to keep a hold upon the government; but in other cases they both persuade the people at the start and afterwards repeat the persuasion and govern them with their consent.
