The aim of this article, firstly, is to outline the theoretical contours of the notion of convolution as it is considered in this issue. Convolution, as a device, organizes a certain number of trajectories in our mental libraries. To do this, it must have a fulcrum, an operator of readability, in this case Hubert Aquin’s work, one or more figures, and an act of memory since memory is what makes it possible to trace axes in the territory of books read. This device operates in “corpus creation” in three ways: anthology, series and genealogy. Secondly, we put this notion to the test by making Trou de mémoire an operator of readability in relation to an anthological corpus (the novels awarded the Governor General between 1970 and 1985), illuminated by a figure, that of the sorcerer-shaman-pharmacist as it appears in the decade of the 1970s.
