Preparing the third edition I had recognised that my book was turning into something of an obituary notice. The project initiated by Malinowski and Radcliffe-Brown underwent a crisis in the 1970s. A different social anthropology emerged in the post-colonial world. Research students who came into the discipline in the 1960s were influenced by structuralism and by the Marxist ideas of the period. They took note of changing fashions in American cultural anthropology, which was going through a transformation of its own. Some were especially influenced by feminist ideas. Others went into new sub-fields, notably medical anthropology, visual anthropology and cognitive anthropology.
