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.
Living organisms including humans are social when they live collectively in interacting populations, whether they are aware of it, and whether the interaction is voluntary or involuntary.
Cultural anthropology is not valuable because it uncovers the archaic in the psychological sense. It is valuable because it is constantly rediscovering the normal.
Edward Sapir Cultural Anthropology and Psychiatry (1932), p. 515
Anthropology is destined to revolutionise the political and the social sciences as radically as bacteriology has revolutionised the science of medicine.
