"In this bold, wide-ranging, and ambitious work, Worsley makes a powerful case for the plurality of knowledge systems. He questions our definitions of culture by looking at the ways cultures are differentiated within the group or national boundaries that are thought to contain them, and the ways in which they spill out of those borders to feed into a global mass society. On the way, he treats us to a lively and accessible examination of the diversity of Australian aboriginal thought. "--Jacket.
