The Mediating Role of Discoursing in Activity

Discoursing, the use of language in interaction with others, plays a part in almost every human activity. Indeed, some have argued that it is discoursing that has made possible the cumulative 5 development of culture over the course of our species’ history. Whether or not that is correct, there can be no question that the ability, with the aid of linguistic discourse, to coordinate action, and to reflect together on the relationship between actions and their intended and achieved results, has been an essential contributor. The question is, How should we theorize the relationship between discoursing and the forms of joint activity in which it occurs? At the present time, not only do 10 we not have an answer to this question but the question has hardly been addressed within activity theory. My aim in this article is to offer some suggestions that may help to advance this project. To this end, I put forward and attempt to justify the argument that discourse always functions to mediate the action in which it serves as an operational means and that the distinctions that need to be made between different kinds of discourse can best be handled with the conceptual tools of 15 genre theory.
