Slavoj Zizek is undoubtedly one of the world’s leading cultural critics. His witty, psychoanalytically-inspired analyses of contemporary society have almost single-handedly revived the notion of ideology. His brilliant commentaries on the French psychoanalyst Jacques Lacan and the 19th century German Idealists have brought alive their often difficult ideas for a new generation of readers. But does Zizek have anything to say in his own right? Is there a system of thought that we can properly call Zizekian? This book argues that there is, through a reading of two terms in his work - the master-signifier and the act. Featuring an interview with Zizek himself, Slavoj Zizek: Live Theory presents a snapshot of the Zizek system ideal for undergraduates in social and cultural theory and philosophy.
