“We embrace, in our soul, two cities, one great and truly belonging to all, in which are found gods and men; in which we concern ourselves not in the affairs of this or that small corner of the earth, for the limits of our city are measured by the farthest corners reached by the sun. The other city is that which is ascribed to us by the circumstances of our birth. Athens for some, Carthage for others or still other cities, for other people, whose administration is the concern not of all human beings, but of those who happen to live there.”

Seneca, On Leisure, 4.1.
