The narration which constitutes L’Écart as a response to the enigma of the death of Ahmed Nara – the archaeologist character, in a foucaldian sense, of Mudimbe’s novel – and to the failure of the autopsy supposed to account for it. From the textual counter-inscription of such a figure of the anatomo-clinic enactment enlightened by Foucault in The Birth of the Clinic, this article analyses, in words of “crossings”, a narrative renewal and deconstruction of that discourse on the inwardness, in order to identify the strategies and tactics of a writing of knowledge on an African cultural identity which inherits Western epistemological frameworks.
