This document discusses key concepts in anthropological understanding of culture. It introduces practice theory, which recognizes that cultures shape individuals but individuals also influence cultural change. Culture exists at multiple levels, from national to subcultural. Ethnocentrism judges other cultures, while cultural relativism evaluates behaviors in their own cultural contexts. Mechanisms of cultural change include diffusion, acculturation, and independent invention. Globalization increasingly interlinks societies through economic, political, and communication forces.
