Michel Foucault's new posthumous book Confessions of the Flesh, translated from the French by Robert Hurley; edited and with a "Foreword" by Frederic Gros (New York: Pantheon Books, 2021) is devoted to examining primary sources to discover the ways in which ancient Western Christians constructed a distinctively Western Christian self. But I see this process as involving the inward turn of consciousness (in Ong's terminology).
