The anthropology of religion involves the study of religious institutions in relation to other social institutions, and the comparison of religious beliefs and practices across cultures.
In the 19th century, cultural anthropology was dominated by an interest in cultural evolution; most anthropologists assumed that there was a simple distinction between primitive and modern religion and tried to provide accounts of how the former evolved into the latter. In the 20th century most anthropologists rejected this approach. Today the anthropology of religion reflects the influence of, or an engagement with, such modern theorists as Karl Marx, Sigmund Freud, Emile Durkheim, and Max Weber. They are especially concerned with how religious beliefs and practices may reflect political or economic forces; or the social functions of religious beliefs and practices.
Anthropological approaches to religion reflect a more general tension within anthropology: the discipline defines itself as a science in that all anthropologists base their interpretations and explanations on empirical evidence (and many anthropologists are concerned with developing universal models of human behavior), and the discipline also defines itself in terms of the seriousness with which it takes local beliefs and practices (see cultural relativism), and its commitment to understanding different cultures in their own terms through participant observation.
Thus, although many Westerners (including anthropologists) have rejected religion out of hand as being unscientific, virtually all anthropologists assume that there must be good reasons for the endurance and importance of religion and, by implication, assume that religious beliefs and practices are in some sense reasonable. In order to determine the reasons for the importance of religion, however, anthropologists generally move beyond the literal claims of any religion to look at its metaphorical meaning or latent social functions.
One major problem in the anthropology of religion is the definition of religion itself. At one time anthropologists believed that certain religious practices and beliefs were more or less universal to all cultures at some point in their development, such as a belief in spirits or ghosts, the use of magic as a means of controlling the supernatural, the use of divination as a means of discovering occult knowledge, and the performance of rituals such as prayer and sacrifice as a means of influencing the outcome of various events through a supernatural agency, sometimes taking the form of shamanism or ancestor worship,. Today, anthropologists debate, and many reject, the cross-cultural validity of these categories (often viewing them as examples of European primitivism). Anthropologists have considered various criteria for defining religion ? such as a belief in the supernatural or the reliance on ritual ? but few claim that these criteria are universally valid.
In Western culture, religion has become more or less synonymous with monotheism and the various moral codes that monotheism prescribes. Moral codes have also evolved in conjunction with Hindu and Buddhist beliefs, independent of monotheism. However, prescriptive moral codes or even normative ethical codes are not a necessary component of religious beliefs or practices any more than they are a necessary component of science and the scientific method.
