Originally published in 1955, this book developed from a series of lectures delivered for the Divinity Faculty of Cambridge University during 1953. It presents an account of the increasing secularisation of Western culture and its effect on religious life and thought, seeking to affirm the value of Christianity in a changing world. Textual discussion incorporates, among other things, the decline in the influence of Christianity in the home, the conflict between science and religion and changes in moral standards. A comprehensive bibliography is also included. This book will be of value to anyone with an interest in the history of Christianity and philosophy.
