The document discusses the importance and functions of culture. It provides rules for proper conduct in society and allows humans to overcome physical disadvantages through tools like fire, clothing, shelter and food. Culture also provides concepts of family, nation and class. The document then discusses cultural relativism, which is the idea that practices considered immoral by some groups may be accepted by others with different cultural orientations. According to sources cited, cultural relativism holds that values and beliefs arise from cultural contexts and are therefore relative to those cultures. It is a key methodological concept in anthropology used to understand cultures neutrally without value judgments.
