Most cultures consider themselves as the “center of the world.” For example, the Chinese called themselves “the central kingdom.” The Greeks called the lands to their. East “the East” and the lands to their West “the West” while considering themselves “the center.” The Romans look that way of talking from the Greeks, and today it is used by speakers of English.”
When anybody thinks of his/her group as being the center of the universe, it means that what the group appreciates, practices, or believes in is the only correct way, and those of other ethnic group are not. People tend to make judgement of other group based on their own values. Many times they see other groups as inferior. They tend to see themselves as the only real people.
