These considerations embolden me to approach with some confidence even the aboriginal religions of America, so often stigmatized as incoherent fetichisms, so barren, it has been said, in grand or beautiful creations. The task bristles with difficulties. Carelessness, prepossessions, and ignorance have disfigured them with false colors and foreign additions without number. The first maxim, therefore, must be to sift and scrutinize authorities, and to reject whatever betrays the plastic hand of the European. For the religions developed by the red race, not those mixed creeds learned from foreign invaders, are to be the subjects of our study. Then will remain the formidable undertaking of reducing the authentic materials thus obtained to system and order, and this not by any preconceived theory of what they ought to conform to, but learning from them the very laws of religious growth they illustrate. The historian traces the birth of arts, science, and government to man's dependence on nature and his fellows for the means of self-preservation. Not that man receives these endowments from without, but that the stern step-mother, Nature, forces him by threats and stripes to develop his own inherent faculties. So with religion: The idea of God does not, and cannot, proceed from the external world, but, nevertheless, it finds its _historical_ origin also in the desperate struggle for life, in the satisfaction of the animal wants and passions, in those vulgar aims and motives which possessed the mind of the primitive man to the exclusion of everything else. There is an ever present embarrassment in such inquiries. In dealing with these matters beyond the cognizance of the senses, the mind is forced to express its meaning in terms transferred from sensuous perceptions, or under symbols borrowed from the material world. These transfers must be understood, these symbols explained, before the real meaning of a myth can be reached. He who fails to guess the riddle of the sphynx, need not hope to gain admittance to the shrine. With delicate ear the faint whispers of thought must be apprehended which prompt the intellect when it names the immaterial from the material; when it chooses from the infinity of visible forms those meet to shadow forth Divinity.
