[1289a] [loeb_subsection_4] but the proper course is to bring forward an organization of such a sort that men will easily be persuaded and be able in the existing circumstances to take part in it, since to reform a constitution is no less a task than to frame one from the beginning, just as to re-learn a science is just as hard as to learn it originally; in addition therefore to the things mentioned the student of politics must also be able to render aid to the constitutions that exist already, as was also said before.Book 3.5. But this is impossible if he does not know how many kinds of constitution there are; but at present some people think that there is only one kind of democracy and one kind of oligarchy, but this is not true. [loeb_subsection_5] Hence he must take in view the different varieties of the constitutions, and know how many there are and how many are their combinations. And after this it needs this same discrimination also to discern the laws that are the best, and those that are suited to each of the forms of constitution. For the laws should be laid down, and all people lay them down, to suit the constitutions—the constitutions must not be made to suit the laws; for a constitution is the regulation of the offices of the state in regard to the mode of their distribution and to the question what is the sovereign power in the state and what is the object of each community, but laws are distinct from the principles of the constitution, and regulate how the magistrates are to govern and to guard against thosewho transgress them. [loeb_subsection_6] So that clearly it is necessary to be in possession of the different varieties of each form of constitution, and the number of these, even for the purpose of legislation; for it is impossible for the same laws to be expedient for all oligarchies or democracies if there are really several kinds of them, and not one sort of democracy or oligarchy only.
[loeb_section_2] [loeb_subsection_1] And inasmuch as in our first inquiryBook 3.5. about the forms of the constitution we classified the right constitutions as three, kingship, aristocracy and constitutional government, and the deviations from these as three, tyranny from kingship, oligarchy from aristocracy and democracy from constitutional government, and about aristocracy and kingship we have spoken (for to study the best constitution is the same thing as to speak about the forms that bear those names, since each of them means a system based on the qualification of virtue equipped with means), and as also the question what constitutes the difference between aristocracy and kingship and when a royal government is to be adopted has been decided before, it remains to discuss the form of constitution designated by the namei.e. πολιτεία, polity, which denotes not only a constitution of any form, but also (like our term constitutional government) a particular form, viz., a republic, cf. Book 3.5.2. common to them all, and the other forms, oligarchy, democracy and tyranny. [loeb_subsection_2] Now it is manifest also which of these deviationsThe three forms of constitution last mentioned. is the worst and which the second worst. For necessarily the deviation from the first and most divine must be the worst, Corruptio optimi pessima, a Socratic notion: the men of the best natural gifts, when educated, are the worst, Xen. Mem. 4.1.3. and kingship must of necessity either possess the name only, without really being kingship,
[1289b] or be based on the outstanding superiority of the man who is king; so that tyranny being the worst form must be the one farthest removed from constitutional government, and oligarchy must be the second farthest (for aristocracy is widely separated from that constitution), while democracy must be the most moderate. [loeb_subsection_3] An account of their relative merits has indeed already been given also by one of the former writers, Plat. Stat. 302a ff. though not on the same principle as ours; for he inclined to judge that there were good varieties of all the forms, for instance a good sort of oligarchy and so on, and that democracy was the worst among these, but the best among the bad varieties, [loeb_subsection_4] whereas we say that the deviations are wholly wrong, and that it is not right to speak of one form of oligarchy as better than another, but only as less bad. But let us for the present dismiss the question of a classification of this nature. Our business is first to distinguish how many different forms of the constitutions there are, assuming that there do exist several kinds of democracy and of oligarchy; [loeb_subsection_5] next, which form is most general, and which most desirable after the best constitution, and also if there exists some other form that is aristocratic in nature and well constructed but not fitted to the largest number of cities, which this is; next, which of the other forms too is desirable for what people (since probably for some democracy is necessary more than oligarchy, and for others oligarchy more than democracy);and after this, in what way should one proceed who wishes to set up these constitutions, I mean the various forms of democracy and of oligarchy; and finally, when as far as possible we have concisely touched upon all these questions, we must endeavor to review what are the agencies that destroy and what are those that preserve constitutions generally and each variety of constitution in particular, and what are the causes by which it is most natural for these events to be brought about.
[loeb_section_3] [loeb_subsection_1] Now the reason of there being several forms of constitution is that every city has a considerable number of parts. For in the first place we see that all the cities are composed of households, and then again that of this multitude some must necessarily be rich and some poor and some between the two, and also of the rich and the poor the former class is heavy-armed and the latter without armor. And we see that one portion of the common people is agricultural, another engaged in trade and another mechanic. And the upper classes have distinctions also corresponding to their wealth and the amounts of their property (for example in a stud of horses—for it is not easy to rear horses without being rich, [loeb_subsection_2] and this is why in ancient times there were oligarchies in all the states whose strength lay in their cavalry, and they used to use horses for their wars against their neighbors, as for instance did the Eretrians and Chalcidians and the people of Magnesia on the Maeander and many of the other Asiatic peoples). Moreover in addition to differences in wealth there is the difference of birth, and that in regard to virtue,
