The theoretical school of postmodernism claims that it is impossible for anyone to have objective and neutral knowledge of another culture. This view comes from the notion that we all interpret the world around us in our own way according to our language, cultural background, and personal experiences. In other words, everybody has their own views based on his or her social and personal contexts. Because of this aspect of human nature, anthropologists can never be unbiased observers of other cultures. When postmodern anthropologists analyze different societies, they are sensitive to this limitation. They do not assume that their way of conceptualizing culture is the only way.
The postmodernists believe that anthropological texts are influenced by the political and social contexts within which they are written. Therefore, it is unreasonable when authors try to justify their interpretations and underlying biases by using the concept of objectivity. The postmodernists claim that the acceptance of an interpretation is ultimately an issue of power and wealth. In other words, we tend to legitimize particular statements represented by those with political and economic advantage. In order to heighten sensitivity towards those who are not part of mainstream culture, the postmodernists often promote unpopular viewpoints, such as those of ethnic minorities, women and others through their works.
The postmodern anthropologists gave other anthropologists an opportunity to reconsider their approaches of cultural analysis. The anthropologists try to become sensitive to their unconscious assumptions. For example, anthropologists now consider whether they should include in ethnographies different interpretations of culture other than their own. Furthermore, anthropologists need to determine their own standards for choosing what kind of information can be counted as knowledge. This reflection leads anthropologists to enrich their work.
At the same time, the challenges by postmodernists often result in backlash from those who feel their understandings are threatened. Some anthropologists claim that the postmodernists rely on a particular moral model rather than empirical data or scientific methods. This moral model is structured by sympathy to those who do not possess the same privilege that the mainstream has in Western societies. Therefore, postmodernism will undermine the legitimacy of anthropology by introducing this political bias. Another typical criticism on postmodernism comes from the fear of extremely relativistic view. Such critics argue that postmodernism will lead to nihilism because it does not assume a common ground of understanding. Some opponents claim that postmodernism will undermine universal human rights and will even justify dictatorship. Postmodernism is an ongoing debate, especially regarding whether anthropology should rely on scientific or humanistic approaches.
