Langages - Année 2004 - Volume 38 - Numéro 154 - Pages 59-73Marianne Doury: Classification of arguments on ordinary discourses. The representations ordinary speakers have about argumentative procedures is necessary to the scientific analysis of argumentation itself. Actually, this ordinary knowledge of argumentation is of great influence on the strategies speakers use in specific contexts. In particular, their perception of the social legitimacy and value of an argument is crucial for their choices when criticising the antagonist discourse. The question arises of the homology of scientific and non-scientific categorisations of arguments and of their respective use in argumentative interactions. 15 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
