The volume provides a multidisciplinary approach of the discursive dimension of power. It challenges the usual conception of discourse and power that underlies most of the current theories in contemporary discourse analysis, and shows that it is unsatisfying in so far as it reduces power to domination and discourse to power technology. In opposition to such a conception, an alternative model of power-in-discourse is constructed. It is called "Dialogical Model" in accordance with its being grounded in a dialogical conception of discourse that naturally leads to a participative conception of power (as empowerment). Part One provides the DM with theoretical and philosophical foundations, while Part Two affords empirical evidence by applying the DM to such typical situations as journalistic discourse under censorship, classroom sessions, and children interaction in a problem-solving situation.
