Citizenship

You would have addressed a letter to "E. Rushmore Coglan, Esq., the Earth, Solar System, the Universe," and have mailed it, feeling confident that it would be delivered to him.
― O. Henry, "A Cosmopolitan in a Cafe" in The Four Million, 1903

Frequently consider the connection of all things in the Universe. . . . We should not say ‘I am an Athenian’ or ‘I am a Roman’ but ‘I am a Citizen of the Universe'.”
― Marcus Aurelius, Meditations, 161 to 180 AD

The first person to have said such a thing was Diogenes the Cynic (4th Century BCE). Diogenes Laertius (3rd Century AD) said of Diogenes the Cynic, “When asked where he was from, he said 'I am a world-citizen.'”

Oh, we come on the ship
  they call the Mayflower,
We come on the ship
  that sailed the moon,
We come in the age’s
  most uncertain hour,
And sing an American tune.

― Paul Simon, American Tune, 1973
