This article aims to present, in its broadest terms, the role played by Saint Augustine in the course The hermeneutics of the subject. We thus want to emphasize that the reference to the Bishop of Hippo is fundamental in several aspects of Foucault›s thought, from the moment the processes of subjection are displaced to the question of subjectivation—that is, to the set of techniques that aim to establish the subject›s relationship with himself. Here, we situate Augustine›s position within the question of memory and meditation, mediated by the confrontation with Platonism and the Stoics, to show to what extent Augustine approaches and departs from these two models.
