Tree concepts of discourse: Foucault, Laclau, Habermas Te aim of this article is to examine three currently dominant concepts of discourse developed by Michel Foucault, Ernesto Laclau and Jürgen Habermas. I purpose- fully relinquish the term “theory of discourse” as at the core of my argument is the idea that such a theory is, in fact, non-existent. An essential challenge that social sciences scholars who use discourse analysis face is locating their own research in a broader methodological framework in which a particular concept of discourse was formulated. As a result, theoretical choices involved in research, such as, for example, the notion of subjectivity, the concept of the social world and the rela- tionship between discourse and everyday language, are essentially infuenced by this framework. I argue that the concepts of discourse discussed in the following ofer neither a coherent methodological agenda nor a coherent theoretical vision; CULTURE – SOCIETY – EDUCATION NO. 2 (12) 2017 POZNAN Lotar Rasiński Dolnośląska Szkoła Wyższa we Wrocławiu ABSTRACT The aim of this article is to examine three currently dominant con- cepts of discourse, developed by Michel Foucault, Ernesto Laclau and Jürgen Habermas. I argue that these concepts of discourse constitute neither a coherent methodological agenda nor a coherent theoretical vision. That means that the reference to discourse will always imply engaging with a particular theoretical framework. I briefy discuss the theoretical traditions from which these concepts emerged and point to the essential elements which the respective concepts of discourse derived from these traditions. Concluding, I examine differences be- tween and similarities in the discussed concepts, whereby I address, in particular, the relationship between discourse and everyday lan- guage, the notion of subjectivity and the concept of the social world.
