The document discusses the relationship between language and culture/society in 3 main points: 1) Language is intrinsically tied to culture and thinking - when we learn language, we learn the associated beliefs and perspectives of the culture. 2) The Sapir-Whorf hypothesis suggests that language influences thought and culture, though it does not fully explain their formation. Other researchers see language and culture evolving together through diffusion and assimilation. 3) Cross-cultural communication requires recognizing linguistic differences between cultures while also finding common ground, like in trade, to facilitate understanding between groups.
