If we are really desirous of obtaining information regarding present religious phenomena, it is plain that we should adopt the scientific method and turn our attention to the remote past, where, by careful and systematic investigation, we are enabled to perceive the earliest conception of a creative force and the fundamental basis of all religious systems, from which may be traced the gradual development of the god-idea. CHAPTER I. SEX THE FOUNDATION OF THE GOD-IDEA. In the study of primitive religion, the analogy existing between the growth of the god-idea and the development of the human race, and especially of the two sex-principles, is everywhere clearly apparent. "Religion is to be found alone with its justification and explanation in the relations of the sexes. There and therein only."(3) 3) Hargrave Jennings, Phallicism. As the conception of a deity originated in sex, or in the creative agencies female and male which animate Nature, we may reasonably expect to find, in the history of the development of the two sex-principles and in the notions entertained concerning them throughout past ages, a tolerably correct account of the growth of the god-idea. We shall perceive that during an earlier age of human existence, not only were the reproductive powers throughout Nature, and especially in human beings and in animals, venerated as the Creator, but we shall find also that the prevailing ideas relative to the importance of either sex in the office of reproduction decided the sex of this universal creative force. We shall observe also that the ideas of a god have always corresponded with the current opinions regarding the importance of either sex in human society. In other words, so long as female power and influence were in the ascendency, the creative force was regarded as embodying the principles of the female nature; later, however, when woman's power waned, and the supremacy of man was gained, the god-idea began gradually to assume the male characters and attributes. Through scientific research the fact has been observed that, for ages after life appeared on the earth, the male had no separate existence; that the two sex-principles, the sperm and the germ, were contained within one and the same individual. Through the processes of differentiation, however, these elements became detached, and with the separation of the male from the female, the reproductive functions were henceforth confided to two separate individuals.
