Examining Adorno’s political experiences and assessing his engagement with Marxist as well as liberal theory, Hammer looks at the development of Adorno’s thought as he confronts Fascism and modern mass culture. He then analyzes the political dimension of his philosophical and aesthetic theorizing. By addressing Jürgen Habermas’s influential criticisms, he defends Adorno as a theorist of autonomy, responsibility and democratic plurality. He also discusses Adorno’s relevance to feminist and ecological thinking. As opposed to those who see Adorno as someone who relinquished the political, Hammer’s account shows his reflections to be, on the most fundamental level, politically motivated and deeply engaged.
