This work aims to read the course Le gouvernement de soi et des autres given by Michel Foucault in 1983 at the Collège de France. It seeks to reflect on philosophy as a form of veridiction. Political parrhesia is a form of philosophical truth-telling that occurs at the intersection of philosophy and politics. The work analyzes two spaces established in Antiquity for the exercise of political parrhesia: the first is the democratic city, the second, the soul of the Prince. Through an analysis of Euripides' tragedy Ion, which reflects on democratic parrhesia, and Plato's Letter VII, which reflects on autocratic parrhesia, we arrive at the question of how the concept of parrhesia, which emerged in the early days of our culture, that is, in Greek Antiquity, can find echoes in Modernity through the reflection of Kant's text on the Aufklärung. The result is a reflection on the relevance of philosophy today and its contribution to a possible articulation between the government of oneself and of others.
