Although there is no lack of efforts to read Foucault and Nietzsche together or indeed to align Foucault and Heidegger, Foucault scholarship overall tends to be split on these same terms. The author argues that the opposition is misleading for the complicated reason that Foucault’s Heidegger can only be understood on Nietzschean terms while and at the same time, Foucault’s Nietzsche only takes place by way of Heidegger albeit (and this point simply cannot be overemphasized) a very Frencophone reading of Heidegger.
