This article analyses the way in which Philippe Denis modified his poems from one publication to the next. The philological approach focuses on Alimentation générale and Petits traités d’aphasie lyrique, collections that provide a window on the characteristics of this reworking process. We draw on the poetological works of Cohen, Dessons, Joubert and Roukhomovsky in order to highlight the meanings of the fragments studied and to establish in this way the share of coherence and innovation inherent in Denis’s work.
