Terry Eagleton is the foremost Marxist cultural theorist of our time. In the first book-length study of this highly influential figure, David Alderson provides detailed discussions of Eagleton's Marxism and his engagements with postmodernism, as well as an evaluation of his interventions in Irish Studies. Each of the chapters in this important intervention in current theoretical debates offers accessible contextualization of the key issues and provides detailed analyses of Eagleton's literary criticism. Alderson shows that the complex relations between nature, culture and ideology, body, subjectivity and authority are at the heart of Eagleton's ethical and political concerns. He goes on to demonstrate that these relations inform the theorist's critical examinations of such literary works as Wuthering Heights and The Merchant of Venice, and his treatment of W. B. Yeats and Oscar Wilde.
