Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. The Idea of God in Early Religions by F. B. Jevons was first published in 1910. The book contains an engaging discussion of the concept of God in terms of its development in the early stages of religion.
