Among the lower tribes the religious life is still most powerful in influencing their early life. Mr. Tylor, in his valuable work on _Primitive Culture_, has devoted a good part of two large volumes to the treatment of early religious belief. While recognizing that there is no complete definition of religion, he holds that "belief in spiritual beings" is a minimum definition which will apply to all religions, and, indeed, about the only one that will. The lower races each had simple notions of the spiritual world. They believed in a soul and its existence after death. Nearly all believed in both good and evil spirits, and in one or more greater gods or spirits who ruled and managed the universe. In this early stage of religious belief philosophy and religion were one. The belief in the after life of the spirit is evidenced by implements which were placed in the grave for the use of the departed, and by food which was placed at the grave for his subsistence on the journey. Indeed, some even set aside food at each meal for the departed; others, as {115} instanced by the Greeks, placed tables in the burying ground for the dead. Many views were entertained by the early people concerning the origin of the soul and its course after death. But in all of the rude conditions of life religion was indefinite and uncultured. From lower simple forms it arose to more complex systems and to higher generalizations. Religious influence on progress has been very great. There are those who have neglected the subject of religion in the discussion of the history of civilization. Other writers have considered it of little importance, and still others believe it to have been a positive hindrance to the development of the race. Religion, in general, as practised by savage and barbarous races, based, as it is largely, on superstition, must of a necessity be conservative and non-progressive. Yet the service which it performs in making the tribe or family cohesive and in giving an impetus to the development of the mind before the introduction of science and art as special studies is, indeed, great. The early forms of culture are found almost wholly in religious belief and practice.
