Examining everyday language and drawing on a wide range of research, Words and Minds takes a lively look at the evolution of language and how we use language to get things done. Neil Mercer offers a fresh perspective on the relationship between thought and language, focusing on the use of language as a tool for thinking together -- interthinking -- which enables people to develop shared understanding, influence each other, and solve problems collectively. He analyzes real-life examples of language being used effectively -- and not so effectively -- in many different settings. From school to the workplace, from the courtroom to the Internet, Words and Minds offers valuable and practical insights into how we use language to make sense of the world together.
