Some sensitive issues in the use and development of the anthropological theory of the didactic

This presentation repeats the opening lecture that the author gave on January 23, 2018 in Autrans (France) during the 6th International Congress on the ATD. Something of the oral form has been deliberately preserved in the text proposed here to the reader. As the title indicates, the aim was to draw attention to certain difficulties observed in the reception and use of the ATD. It is these difficulties that the structure of the text seeks to highlight and help overcome. After having underlined the question of the vocabulary specific to the ATD, we successively examine its theory of cognition, which is the basis of the ATD, then the cardinal notion of the possibly didactic, before moving on to the theory of praxeologies, which has undoubtedly received the greatest diffusion so far, and to progress by deepening the dialectic of persons and institutional positions, before specifying the concept of inquiry, which is at the heart of the current and future developments of the ATD
