Interest in Theodor W. Ador continues to grow in the English-speaking world as the significance of his contribution to philosophy, social and cultural theory, as well as aesthetics is increasingly recognized. Espen Hammer's lucid book is the first to properly analyse the political implications of his work, paying careful attention to Ador's work on key thinkers such as Kant, Hegel and Benjamin. Examining Ador's political experiences and assessing his engagement with Marxist as well as liberal theory, Hammer looks at the development of Ador's thought as he confronts Fascism and modern mass culture. He then analyzes the political dimension of his philosophical and aesthetic theorizing. By addressing Jurgen Habermas's influential criticisms, he defends Ador as a theorist of automy, responsibility and democratic plurality. He also discusses Ador's relevance to feminist and ecological thinking. As opposed to those who see Ador as someone who relinquished the political, Hammer's account shows his reflections to be, on the most fundamental level, politically motivated and deeply engaged. This invigorating exploration of a major political thinker is a useful introduction to his thought as a whole, and will be of interest to scholars and students in the fields of philosophy, sociology, politics and aesthetics.
