I came across James Clifford on another site while researching my paper. He’s a professor of consciousness at the University of California at Santa Cruz, and he writes extensively on indigenous issues, particularly on topics like the indigenous diaspora (as far as I can tell, he invented the term). This is a relevant issue for me as I am writing about urban indigeneity. I think Clifford has interesting things to say about the modern indigenous experience that usually challenge western mythologies.
His site includes many of his publications for download. Two that I have come across before are “Varieties of Indigenous Experience: Diasporas, Homelands, Sovereignties” and “Indigenous Articulations” but some of his other work, which has an anthropological and ecological perspective, looks interesting as well.
