Cosmopolitanism \Cos`mo*pol"i*tan*ism\ (k?z`m?-p?l"?-tan-?z'm), n. The quality of being cosmopolitan; cosmopolitism.
n. The idea that all of humanity belongs to a single moral community.
Cosmopolitanism is the ideology that all human beings belong to a single community, based on a shared morality. A person who adheres to the idea of cosmopolitanism in any of its forms is called a cosmopolitan or cosmopolite. A cosmopolitan community might be based on an inclusive morality, a shared economic relationship, or a political structure that encompasses different nations. In a cosmopolitan community individuals from different places (e.g. nation-states) form relationships of mutual respect. As an example, Kwame Anthony Appiah suggests the possibility of a cosmopolitan community in which individuals from varying locations (physical, economic, etc.) enter relationships of mutual respect despite their differing beliefs (religious, political, etc.).
Various cities and locales, past or present, have or are defined as "cosmopolitan"; that does not necessarily mean that all or most of their inhabitants consciously embrace the above philosophy.
