Book 6

Book 7 in some editions, Book 8 in others.We have already discussedBook 4, 1297b 35 ff. how many and what are the varieties of the deliberative body or sovereign power in the state, and of the system of magistracies and of law-courts, and which variety is adapted to which form of constitution, and alsoBook 5. the destruction of constitutions and their preservation, from what sort of people they originate and what are their causes. But as a matter of fact since there have come into existence several kinds of democracy and similarly of the other forms of constitution, it will be well at the same time to consider1318b—1319a 6. any point that remains about these varieties, and also determine the mode of organization appropriate and advantageous for each. And further we must also investigateThese topics do not occur in the extant work. the combinations of all the modes of organizing the actual departments of state that have been mentioned,i.e. the deliberative, executive and judicial, see 1297b 41 ff.
1317a
for these modes when coupled together make the constitutions overlap, so as to produce oligarchical aristocracies and republics inclining towards democracy. I refer to the combinations which ought to be investigated but have not at present been studied, for example if the deliberative body and the system of electing magistrates are organized oligarchically but the regulations as to the law-courts aristocratically, or these and the structure of the deliberative body oligarchically and the election of magistracy aristocratically, or if in some other manner not all the parts of the constitution are appropriately combined
