When people talk about things such as language, the mind, globalisation or weeds, they are less discussing the outside world than objects they have created collaboratively by talking about them. Wolfgang Teubert shows that meaning cannot be found in mental concepts or neural activity, as implied by the cognitive sciences. He argues instead that meaning is negotiated and knowledge is created by symbolic interaction, thus taking language as a social, rather than a mental, phenomenon. Discourses, Teubert contends, can be viewed as collective minds, enabling the members of discourse communities to make sense of themselves and of the world around them. By taking an active stance in constructing the reality they share, people thus can take part in moulding the world in accordance with their perceived needs.
