Book 3
1276b
For inasmuch as a state is a kind of partnership, and is in fact a partnership of citizens in a government, when the form of the government has been altered and is different it would appear to follow that the state is no longer the same state, just as we say that a chorus which on one occasion acts a comedy and on another a tragedy is a different chorus although it is often composed of the same persons, and similarly with any other common whole or composite structure we say it is different if the form of its structure is different—for instance a musical tune consisting of the same notes we call a different tune if at one time it is played in the Dorian mode and at another in the Phrygian. Therefore if this is the case, it is clear that we must speak of a state as being the same state chiefly with regard to its constitution; and it is possible for it to be called by the same or by a different designation both when its inhabitants are the same and when they are entirely different persons. But whether a state is or is not bound in justice to discharge its engagements when it has changed to a different constitution, is another subject.
