Russell on Religion presents a comprehensive and accessible selection of Bertrand Russell's writing on religion and related topics from the turn of the century to the end of his life. The influence of religion pervades almost all Bertrand Russell's writings from his mathematical treatises to his early fiction. Russell contends with religion as a philosopher, as a historian, as a social critic and as a private individual. The papers in this volume are arranged chronologically for optimum coherence of the development of Russell's thinking and are divided into five main sections: * Personal statements * Religion and Philosophy * Religion and Science * Religion and Morality * Religion and History. Students at all levels will find this a valuable insight into Russell's thought on religion.
