George Lakoff is a cognitive linguist and philosopher known for his work on the relationship between language and thought. He has significantly contributed to the understanding of how metaphors shape our understanding of the world. His theories suggest that our conceptual framework influences our language, which in turn affects our perceptions and actions. Lakoff is also recognized for his analysis of political language, particularly in the context of framing and political discourse. He argues that the way issues are framed can impact public opinion and policy decisions. His insights have been influential in both linguistics and political communication.
