This article seeks to extend existing models of argumentation by considering an important dimension of real-life argumentative discourse: how complex argumentative discussions evolve over time. We define a complex argumentative discussion as a multi-issue discussion, in which the different issues are interrelated in the form of a hierarchy. We claim that justified reframing might be used to transform a single-issue argumentative discussion into a complex argumentative discussion. To illustrate this, we examine the Facebook discourse of the Rhodes Must Fall movement (...) in South Africa. We analyse how reframing is justified by means of arguments, allowing the protagonists to claim as legitimate their reframing of a single issue into a complex argumentative discussion. Our findings complement existing sociological research on social movements by highlighting how their goals are achieved by means of argumentative discourse. (shrink)

This paper investigates the relationship between characterization frames and argumentation in activists’ discourse about the public controversy surrounding fashion sustainability. While previous studies proposing an argumentative approach to frames have acknowledged that frames are related to underlying implicit premises, how frames select certain implicit premises still needs to be systematically explained. Therefore, drawing on a theoretical framework combining Pragma dialectics (van Eemeren 2010 ) with the Argumentum Model of Topics an empirical analysis of a social media corpus has been performed (...) in order to examine the connection between characterization frames and underlying implicit premises. This paper offers both a methodological and a theoretical contribution. From a methodological point of view, it offers linguistic-discursive tools for the analysis of characterization frames. From a theoretical perspective, it shows how characterization frames contribute to construct _endoxa_, i.e. underlying implicit premises, through argumentative patterns. (shrink)
