Radcliffe Brown quoted by Tim Ingold
"‘A pig does not become a hippopotamus … On the other hand a society can and does change its structural type without any breach of continuity.’"
And in his own words...
"THE OBJECTIVE of anthropology, I believe, is to seek a generous, comparative but nevertheless critical understanding of human being and knowing in the one world we all inhabit. The objective of ethnography is to describe the lives of people other than ourselves, with an accuracy and sensitivity honed by detailed observation and prolonged first-hand experience. My thesis is that anthropology and ethnography are endeavours of quite different kinds."
