Whether invented, discovered, implicit, or directly addressed, relations remain the main focus of most anthropological inquiries. These relations, once conceptualized in ethnographic fieldwork as self-evident connections between discrete social units, have been increasingly explored through local ontological theories. This collected volume explores how ethnographies of indigenous South America have helped to inspire this analytic shift, demonstrating the continued importance of ethnographic diversity. Most importantly, this volume asserts that comparative ethnographic research can help illustrate complex questions surrounding relations vis-à-vis the homogenizing effects of modern coloniality.
