Rachid Alaoui offers a critical analysis of the paradoxes presented by the concept of evil, in both its moral and political forms, in the thought of Hanna Arendt, while simultaneously presenting the naturalistic and metaphysical aspects of the concept of evil. It is based on these that the author has deployed the idea of banality, as defined in Arendt’s “banality of evil”, drawn from her famous coverage of the Eichman trials in Jerusalem. This can be viewed alongside the concept of political evil which can be distilled from her The Origins of Totalitarianism and The Life of the Mind. It is based on these that we can ask: what drives us to enquire about the question of evil in the present day? How exactly did Arendt define the banality of evil? How did she treat the problem of political evil and how does political evil relate to totalitarian regimes?
