Final answer:
Supping with Savages illustrates the cultural anthropology concept of cultural relativism by emphasizing the importance of understanding and suspending judgment about other cultures.
Step-by-step explanation:
Cultural relativism is the crucial concept illustrated in the book Supping with Savages by analyzing different cultures and their traditions without judgment. Anthropologists suspend judgment until they gain a clear understanding of the meaning and significance of cultural practices and beliefs. This approach allows for a better understanding of others and promotes cross-cultural relationships. For example, by understanding the rationale behind different cultural norms, anthropologists can work together with people from other cultures to pursue common interests.
