Book excerpt: What is the basis of belief in an era when globalization, multiculturalism and big business are the new religion? Slavoj Zizek, renowned philosopher and irrepressible cultural critic takes on all comers in this compelling and breathless new book. From 'cyberspace reason' to the paradox that is 'Western Buddhism', On Belief gets behind the contours of the way we normally think about belief, in particular Judaism and Christianity. Holding up the so-called authenticity of religious belief to critical light, Zizek draws on psychoanalysis, film and philosophy to reveal in startling fashion that nothing could be worse for believers than their beliefs turning out to be true.
