Anthropology is the study of humans and human behaviour and societies in the past and present. Social anthropology and cultural anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the biological development of humans.
Cultural anthropology is not valuable because it uncovers the archaic in the psychological sense. It is valuable because it is constantly rediscovering the normal.
