Arguing to convince : the rhetoric of scientific discourse

This paper deals with scientific discourse as a rhetorical discourse from the point of view of the structure of the classical parts of oral discourse (and all kinds of discourse). The role of argumentation in discourse, with the perlocutionary goal of convincing the receiver, is studied as the foundation of the rhetorical nature of scientific discourse.
