In lively and lucid prose she explains its relevance for every reader by revealing its wide-ranging impact on our attitudes to society, values, cosmology and knowledge. This book has been hugely influential in many areas of debate - from religion to social theory.

"Professor Douglas writes gracefully, lucidly and polemically. She continually makes points which illuminate matters in the philosophy of religion and the philosophy of science and help to show the rest of us just why and how anthropology has become a fundamentally intellectual discipline." - New Society "Professor Douglas' book sparkles with intellectual life and is characterised by a concern to understand. Right or wrong, sound or idiosyncratic, it presents a rare and exciting spectacle of a mind at work." - Times Literary Supplement
