 The second main source of arguments that ordinary mental content is broad is a series of influential articles by Tyler Burge, including “Individualism and the Mental” (1979). Burge has offered several lines of argument for the externalist view he calls “anti-individualism.” These are helpfully distinguished and described in the Introduction to Burge 2007. One line of argument, closely related to Putnam’s water example, emphasizes the role of the environment in thought about natural kinds. Another line of argument defends anti-individualism about perceptual content. I will consider a third much-discussed line of argument, which relies on the fact that in many cases we intend what we are thinking or talking about to depend to some extent on the beliefs of others in our community, especially those more expert than we.
