Résumé
This thesis has been submitted for the Habilitation to Supervise Research. It consists of two parts. In the first part, the candidate analyses his research career in the fields of 20th century French literature (esp. Raymond Queneau), and literary and linguistic approaches to humour, as an opening to questions of epistemology of literature developed in this second part. The second part, entitled "Questions and perspectives in the didactics of literature: Thinking/teaching literature as an art", presents the current state of research in the didactics of literature, and outlines some of the projects under development in this field, at the crossroads of literary theory, teachers' work analysis and transdisciplinary reflection on the notion of "aesthetic experience".
