In 2018, more than 40 years since the death of Hannah Arendt, considered the most important political philosopher of the 20th century. Her biographical career as a disciple of Jaspers and Heidegger, as an exiled German Jew and finally as an American citizen marked the singular evolution of her thinking, not classifiable in any of the "isms" to use; hence its current affairs and the one that has reappeared on the scene in recent years. This volume brings together the reflections of prominent philosophers, such as Hans Jonas, Richard J. Bernstein or Salvador Giner, who analyze from a very diverse perspective the central themes of Arendt's work. In this way, his figure is shaping up as that of a theoric who can and should take part in our current controversies. Hannah Arendt was never tempted to endorse the words of Hugo von Hofmannsthal, who said a century ago that "it is relatively easy to win the sympathies of the generation to which it belongs": during her lifetime her voice was uncomfortable and still so. That's exactly why you have to listen to her.
