First published in 1906, these four lectures were originally delivered in the Vacation Term for Biblical Study at Cambridge. Evidence is derived from the native tribes of Australia in particular, whom Jevons compares for his discussion. The first lecture considers whether religion has evolved from, or was preceded by a pre-religion, or non-religious, stage of humankind. The following lectures discuss the science of religion and the theory of Evolution, and the relationship between the evolution of religion and the philosophy of religion. This is a fascinating text that will be of particular value to students interested in the history and development of religion in general.
