Judgment After Arendt is both the first full-length study of Hannah Arendt's The Life of the Mind and, at the same time, a philosophical work on the core concepts of thinking, willing and judging. Comprised of Thinking and Willing, her final and most sustained philosophical project, Arendt's work is framed by the 'thought-less' Adolf Eichmann whose 'banality' of mind in committing evil she observed at his trial in Jerusalem.Arendt's project, cut short by her death, was to have included Judgment. Without judgment, she argued, a life of thought and of will can still collude with evil. In analysing Arendt's work Deutscher develops this theme of judgment and shows how, by drawing upon literature, history, myth and idiom, Arendt contributes significantly to contemporary philosophy.
