Cosmopolitanism

Cosmopolitanism is the idea that all human beings are members of a single community. Its adherents are known as cosmopolitan or cosmopolite. Cosmopolitanism is both prescriptive and aspirational, believing humans can and should be "world citizens" in a "universal community". The idea encompasses different dimensions and avenues of community, such as promoting universal moral standards, establishing global political structures, or developing a platform for mutual cultural expression and tolerance.
