Adult union and the consequent development of a family, exists throughout many world cultures. Unlike the United States, where serial monogamy is the prevailing relationship category, many other cultures support a variety of adult unions, which would be illegal or socially unacceptable in the United States. These alternative adult unions can be as diverse as the cultures themselves, confirming that there is no “universal system of ethics” (Dennett 494). Taking a closer look at the “culturally strange” relationship arrangements in other countries, will help to increase Americans’ appreciation for and understanding of the social dynamics within those cultures, which ultimately leads to better cross-cultural communication. I think this communication must occur to prevent “ethics [from settling] into an … equilibrium” (Dennett 494). I believe that the United States should encourage educational programs that discuss and appreciate the diverse cultural traditions such as those of the Na of China, the Tibetans of Nepal and the Indians of India. Cultural relativism is the view that all cultures and beliefs are as equally legitimate as the next. I am convinced that cultural relativism, and not ethnocentrism, needs to be the prime focus of all learning institutions to further encourage the understanding that alternative and seemingly “strange” relationship categories are often adapted by different social groups as a mechanism to cope with economic, religious and culture pressures.
