The publication of Foucault’s courses from the 1950s and 1960s has been planned for some time, and now his 1964 course from Clermont-Ferrand La sexualité is listed as forthcoming in October 2018. Limited details at the moment, but here are the listings on Amazon, Cultura, Decitre and Fnac. It’s coming out with Gallimard/Seuil in the Hautes Etudes series, but is not yet on their website. I
‘d previously heard this would be paired with a 1969 course from Vincennes on a related topic, but it is now listed as followed by ‘Le discours de la sexualité’. I’ll share more details if and when I hear them, or please add any other information in comments.
Update: Thanks to Daniele Lorenzini for confirming that there are two courses in this volume – the 1964 Clermont-Ferrand one, and the 1969 course from Vincennes Le discours de la sexualité. Claude-Oliver Doran, who was involved in the Théories et institutions penales course, is the editor.
Update 2: A few more details here.
Update 3: the Seuil website is here.
