Anthropology studies the phenomenon of man, not simply man's mind, his body, evolution, origins, tools, art, or groups alone, but as parts or aspects of a general pattern, or whole. To emphasize this fact and make it a part of their ongoing effort, anthropologists have brought a general word into widespread use to stand for the phenomenon, and that word is culture.

To a degree that we seldom realize, we depend upon the participation of others in our lives, and upon our own participation in the lives of others. Our success and effectiveness as persons is based upon this participation, and upon an ability to maintain a controlling competence in communicating with others.

It is worthwhile studying other peoples, because every understanding of another culture is an experiment with our own.

The peculiar situation of the anthropological fieldworker, participating simultaneously in two distinct worlds of meaning and action, requires that he relate to his research subjects as an "outsider," trying to "learn" and penetrate their way of life, while relating to his own culture as a kind of metaphorical "native."To both groups he is a professional stranger, a person who holds himself aloof from their lives in order to gain perspective.
