Book 4
1296b
These considerations therefore make it clear which is the best constitution, and why it is the best; and now that the best has been defined, it is not difficult to see, among the other forms of constitution (inasmuch as we pronounce that there are various forms of democracy and various oligarchies), what kind is to be placed first, what second, and what next in this order, by reason of one being better and another worse. For at each stage the form nearest to the best one must necessarily be superior, and the form that is more remote from the middle must be inferior—unless one is judging relatively to given conditions: I make this reservation because it is quite possible that although one form of constitution is preferable it may often be more advantageous for certain people to have another form.
1296b
The next thing after what has been said is to discuss which constitution is advantageous for which people, and what sort of constitution for what sort of people. Now we must first grasp a general principle that applies equally to all sorts of constitution: it is essential that the part of the state that wishes the constitution to remain should be stronger than the part that does not wish it. But every state consists of both quality and quantity: by quality I mean freedom, wealth, education, good birth, and by quantity the superior numbers of the multitude. And it is possible that,while the quality of the state belongs to one among the parts of which the state consists and its quantity to another part—for example the low-born may be more numerous than the noble or the poor than the rich, yet the more numerous class may not exceed in quantity as much as they fall behind in quality. Hence these two factors have to be judged in comparison with one another.
