Aristotle Quote

Most persons think that a state in order to be happy ought to be large; but even if they are right, they have no idea of what is a large and what a small state.... To the size of states there is a limit, as there is to other things, plants, animals, implements; for none of these retain their natural power when they are too large or too small, but they either wholly lose their nature, or are spoiled.
