New in paperback. Hardcover was published in 2014. In this major new work the leading philosopher Slovoj Zizek argues that philosophical materialism has failed to meet the key scientific, theoretical and political challenges of the modern world, from relativity theory and quantum physics to Freudian psychoanalysis and the failure of twentieth-century communism. To bring materialism up to date, Zizek proposes a new foundation for dialectical materialism.
