This introduction focuses on the contemporary fascination with the big questions about God and the supernatural, setting out clearly and fairly what people believe and the reasons they give for believing it. All the major faiths are covered, along with new and alternative movements associated with them. Space is also given to New Age, neo-pagana and occult thought, as well as to spiritualities of human potential and self-enhancement. This text should be especially helpful to students of religion and related subjects, and to geneal readers who want to know more about the most popular and influential beliefs in the world today.
