The Boasian School refers to a theoretical framework in anthropology founded by Franz Boas in the early 20th century. It emphasizes the importance of cultural relativism, arguing that cultures should be understood on their own terms rather than judged by the standards of another culture. This approach challenged the prevailing notions of cultural evolution and hierarchy. Additionally, the Boasian School advocates for rigorous fieldwork and empirical research, promoting the collection of detailed ethnographic data. This methodology has significantly influenced modern anthropology, encouraging scholars to focus on the diversity of human experiences and the complexities of cultural practices across different societies.
