Most people in North America and Western Europe cling to a very dangerous belief: that people are really all the same, that people everywhere want the same things, that people everywhere have the same values. And the things others want and value are the same things that we want and value. This is the great Western humanistic delusion: that everyone is the same, and everyone is like me.
Historically, people saw their encounters through a loyalty and pride in his or her family, clan, tribe, caste, class, nation, religion, and race, and to have suspicion and disdain for those of other families, clans, tribes, castes, classes, nations, religions, and races. Uniquely, in the West, after the Enlightenment, the idea of the “in” group broadened and broadened over time, so that by the second half of the 20th century, identity was increasingly with all of humanity. Anthropologists rejected race as a legitimate scientific category.
