First edition for which it was not drawn from great papers, one of the review copies service. Autograph dedication signed by Michel Foucault to his close friend, academic Robert Mauzi. Their long friendship begins at the Thiers Foundation, where they are both residents, and continues during their career in the faculties of Paris. With Roland Barthes, they form a trio of literati animated with a deep friendship, which evolves in the university spheres and revolutionizes the modern thought. This letter evokes the great role of Mauzi in the life of the author, who accompanied the publication of the brilliant writings of Foucault. Back slightly insolated.
