  Hannah Arendt was one of the seminal political thinkers of the twentieth century. The power and originality of her thinking was evident in works such as The Origins of Totalitarianism, The Human Condition, On Revolution and The Life of the Mind. In these works and in numerous essays she grappled with the most crucial political events of her time, trying to grasp their meaning and historical import, and showing how they affected our categories of moral and political judgment. What was required, in her view, was a new framework that could enable us to come to terms with the twin horrors of the twentieth century, Nazism and Stalinism. She provided such framework in her book on totalitarianism, and went on to develop a new set of philosophical categories that could illuminate the human condition and provide a fresh perspective on the nature of political life.
