Sustainable Development As Communicative Action[Le Developpement Durable Comme Agir Communicationnel]

Sustainable development emerged in the last third of the twentieth century, on the fringes of dominant social practices and representations as much as of constituted knowledge. It quickly established itself as a new principle of organization of collective perceptions and actions, colonizing at the same time language, imaginary, exchanges, techniques, values and standards, at the same time as he imposed himself on scientific theories and scholarly discourses. To set some benchmarks in the history of this emergence is the object of this communication, which describes in broad outlines this singular trajectory, in its political, scientific and ideological dimensions. Then the purpose is to highlight the main effects of this upheaval in the field of social practices, using the theory of conventions and the theory of Communicative Action.
