Theory in Anthropology [PDF ebook] 

This is VII in a series of ten volumes on the Theory in Anthropology. Originally published in 1968, this is a sourcebook that was created by the authors’ need for making accessible in a single volume a sample of those important pieces which are presently scattered in numerous publications, some of which are difficult for the student to obtain. Our second reason had to do with certain convictions they hold about the aims and methods of anthropology.
