A concise nonfiction study examining how human societies understand difference through the lenses of civilization, culture, and evolution. Drawing on philosophical and social-scientific perspectives, the work considers the ways communities classify human development, cultural change, and collective identity. Its focus on human and social evolution suggests an inquiry into the assumptions behind narratives of progress, diversity, and historical transformation. The book is suited to readers interested in cultural theory, the intellectual history of civilization, and questions about how societies interpret their own development over time.
