This dissertation intends to identify and analyse the presence of Augustine of Hippo in the works of Hannah Arendt, focusing on the part ennacted by the augustinian concept of natality in the change undergone by the author in her trajectory: from a first fase dedicated to existencialist filosophycal reflection to a second fase when Hannah Arendt developed her political and historyographic thinking. To achive this goal I will not only analyse the concepct of natality, but also the concepts of birth, beggining, freedom and memory – which hold connections with the concept of natality. It s of central importance for this work Hannah Arendt s dissertation, The Concept of Love in Augustine. I mean to demonstrate how the concept of birth, present in this first work of the author, has given origin to the concept of natality that is inserted in the revised version of the dissertation in the 60 s, and that appears at her most important works, of wich will be analysed here: Origins of Totalitarianism, Human Condition, Between Past and Future, and On Revolution.
