Marsilius of Padua: The Defender of the Peace

We have so far put forward, by way of preliminaries, a global account of the parts of the city; and we have said that it is in their action and perfect mutual intercommunication (not subject to any impediment from outside either) that the tranquillity of the city consists. We now take up the subject of these parts again, so that through a richer elucidation of them (from their activities or ends as well as from the other causes appropriate to them) the causes of tranquillity and its opposite might be further clarified. We shall say, then, that the parts or offices of the city are of six kinds, as Aristotle said in Politics VII, chapter 7: agriculture, manufacture, the military, the financial, the priesthood and the judicial or councillor. Three of these, viz. the priesthood, the military and the judicial, are parts of the city in an unqualified sense, and in civil communities they are usually called the notables. The others are called parts in a broad sense, in that they are functions necessary to the city according to the opinion of Aristotle in Politics VII, chapter 7. And the multitude of these is usually called plebeian. These, then, are the more familiar parts of the city or realm, to which all the others can appropriately be reduced.

Even though the necessity of these parts was stated in the previous chapter, we nevertheless wish to affirm it again in a more definitive fashion: taking it as demonstrated earlier, from what is self-evident, that the city is a community established in order that the human beings within it may live and live well. Now we earlier demarcated two modes of this ‘living’: one, the life or living of this world, viz. the earthly; two, the living or life of another or future world. On the basis of these two modes of living, which man desires as ends, we shall identify the necessity of the distinction between the parts of the civil community.
