Foucault, “Les Hermaphrodites” – forthcoming in September 2025. France 24 reports on this here.

Not that many details, except it will be with Gallimard, and have a preface by Arianna Sforzini and a postface by Éric Fassin. The text is described as ‘substantial’, but it is more like a long essay or part of a book rather a full manuscript.

Update July 2025: Gallimard have a page for the book, with the title Histoire des hermaphrodites, 160 pages. [Update 23 July: now Les Hermaphrodites.] It’s listed as part of the Bibliothèque des Histoires series, in which several of Foucault’s books appeared, including the four volumes of the History of Sexuality. There is a piece by Hocine Bouhadjera about the book at Actualitté.
