The doctrine that numerous distinct ethnic, religious, and cultural groups should and do coexist, and that no single group is superior to others. This is very similar to multiculturalism. The opposite is particularism. Pluralism is also used to refer to art in the 1970s and 1980s, when the great variety of attitudes and style was taken as a sign of cultural vigor. It has been seen as one of the hallmarks of postmodernism, encouraging divergent perceptions of the world, and arguing against the setting of any single standard.Also see feminism and feminist art, gender issues, political correctness, xenophilia, xenophobia, and zeitgeist.
