world citizen, n.All

World citizen (n.) treats ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠nothing as a purely private interest, as a hand or foot gifted with reason would want nothing except by reference to the whole body.

A World citizen (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠an easy idealist phrase: citizenship means rights and duties that make sense only within borders, so Kant's world citizen was really a world-spectator.
