Ernst Bloch is perhaps best known for his subtle and imaginative investigation of utopias and utopianism, but his work also provides a comprehensive and insightful analysis of western culture, politics and society. Yet, because he has not been one of easiest of writers to read his full contribution has not been widely acknowledged. Block developed a complex conceptual framework, and presented this in a prose style which many have found to verge on the impenetrable. In this critical and accessible introduction to one of the most fascinating thinkers of the twentieth century, Vincent Geoghegan unravels much of the mystery of the man and his ideas.
