Written by eleven leading anthropologists from around the world, this volume extends the insights of Fredrik Barth, one of the most important anthropologists of the twentieth century, to push even further at the frontiers of anthropology and honor his memory. As a collection, the chapters thus expand Barth's pioneering work on values, further develop his insights on human agency and its potential creativity, as well as continuing to develop the relevance for his work as a way of thinking about and beyond the state. The work is grounded on his insistence that theory should grow only from observed life.
