Karen Armstrong: "Fundamentalism is a revolt against modernity"

In this week's edition of "The Interview", the writer Karen Armstrong talks candidly to Carrie Gracie about her extraordinary journey -- from convent life as a young nun to becoming one of the world's leading authorities on religion. At the age of seventeen, Karen Armstrong decided to dedicate herself to God. When she left the convent seven years later, deeply disillusioned, she faced one of the most difficult periods of her life. She tells Carrie Gracie why she found readjusting to the world outside so challenging -- it was the 1960s and she had never heard of the Beatles or of the Vietnam war -- and how she eventually found her way and discovered her true vocation as a writer. Since then she has found success and written many books on religion, "The Battle for God", "Muhammad: A Biography of the Prophet" and "Islam: A Short History". She has been invited to address Congress. In this week's programme, she also discusses the origins of fundamentalism, the resurgence of religion in modern life and talks about the West's relationship with Islam.
