A few more parts of Book III over the weekend, if you like. Part V asks whether everyone should be a citizen -- that is, to have a share in both ruling and obeying -- or if some orders of those in the city should be ruled only. This is similar to the debate we had a couple of years ago about the extent of the franchise, but this is the ancient take on the question. Aristotle doesn't give a final answer to the question here, but he does answer the question from the last post: are the virtues of the good man and the good citizen the same? Yes, he tells us, in states where all citizens are part of the ruling class.
After that Aristotle takes on the question of forms of government. We'll stop with Part IX because a new big question comes up in Part X, which is where the ultimate source of sovereignty ought to reside: with the people, or somewhere else? That's a discussion in itself.
