A great deal has been written about Hannah Arendt, especially regarding her reflections on Totalitarianism and "The Banality of Evil." In recent years, however, the radicality of her political philosophy and ethical reflection has been overshadowed.Through an analysis of Arendt's major works -- from The Human Condition 1958 to The Life of the Mind 1978 -- and some of her posthumously published or still unpublished writings -- from The Promise of Politics 2005 to Some Questions of Moral Philosophy 1994 -- this seminar intends to bring to light the complexity and the intentional aporias that mark Arendtian thought. In particular, it examines the role of the an-archic ontology that underlies her philosophy and makes it more interesting and provocative today than ever. In particular, the concepts of power and public space, as well as the notions of critical thinking and ethical subjectivity will be reconsidered through the paradoxical idea of Reiner Schürmann's "principle of anarchy" and the thought of the late Michel Foucault.
