'Confessions of the Flesh' is the final work by the eminent French philosopher and historian Michel Foucault (1926-1984), completed in draft form shortly before his death and published in its original language only in 2018. It continues the project conceived and begun by Foucault in the mid-1970s under the general title 'History of Sexuality,' the range of themes of which extends far beyond sexual relations between people and their understanding in ancient and Western Christian culture. 'Confessions of the Flesh' addresses the development of questions of the flesh in the works of Eastern and Western Church Fathers of the second to fourth centuries, the formation of monastic and ascetic practices related to the body, flesh, and gender during the same period, the Christian regulation of marital relations, and, more broadly, the evolution of the Christian concept of marriage. Behind all these themes emerges the main philosophical stake of the History of Sexuality and, in general, Foucault’s later thought: the study of the formation of subjectivity as a person’s idea of ​​himself and his relationship to himself.
