The Evolution of the Idea of God: An Inquiry Into the Origins of Religions

"The Evolution of the Idea of God: An Inquiry Into the Origins of Religions" by Grant Allen is a comprehensive treatise on the psychological and historical development of the God concept, written in the late 19th century. The book aims to explore the evolution of the idea of deity, tracing its roots from early primitive beliefs through polytheism to the more advanced notions found in monotheistic faiths, particularly Christianity. Allen's investigation is structured around three main parts: the origin of polytheism, the transition to monotheism, and the development of the idea of a triune God in Christianity. The opening of the work sets the stage for this ambitious inquiry by delineating the various schools of thought regarding the nature of religious belief. Allen discusses how humans have grappled with the concept of God, from the most rudimentary understandings in savage societies to the complex theological ideas present in contemporary Christianity. He emphasizes that his approach is not to disprove existing beliefs but to understand the psychological processes that led to their formation. By employing historical documents and examining primitive practices, he aims to elucidate how the worship of many gods transitioned into the worship of a singular, all-powerful deity, ultimately leading to the rich tapestry of religious thought exemplified in modern theologies.
