The inao are peculiar, inasmuch as nothing exactly like them is known. The feather prayer-plumes of some of the Western Indians are used for like purposes, but these are offered directly to the Great Spirit, and not to intermediaries. "Inao, briefly described, are pieces of whittled willow wood, having the shavings attached to the top."[35] Like the Aleutians, when these people kill a bear or other wild animal, they propitiate its spirit by bestowing upon it the most fulsome compliments, and, like the religion of these Indians, the religion of the Ainus has developed along natural lines, and shows certain phallic elements. [35] Batchelor: _The Ainu of Japan_, p. 87. We see from the examples here given, that religious feeling had its origin in the idea of propitiation; in fact, that it was born in fear, and by fear was it fostered. We see, furthermore, that man was not created with religious feeling as a psychical trait, but that he acquired it later on. We see, finally, that religious feeling is based, primarily and fundamentally, on one of the chief laws of nature--self-protection. The evolution and growth of Ethics demonstrate this beyond peradventure. It is not at all probable that man in the beginning, just after his evolution from his ape-like ancestor, had, at first, any belief whatever in supernatural agencies. In his struggle for existence, all of his powers were directed toward the procurement of his food and the preservation of life; the pithecoid man was only a degree higher than the beasts in the scale of animal life. His psychic being, as yet, remained, as it were, _in ovo_, and a long period of time must have elapsed before he began to formulate and to recognize a system of theogony. After years of experience, during which the laws of heredity and progressive evolution played prominent parts, he took precedence over other animals, and his struggle for existence became easier. He then had time to study the wonderful and, to him, mysterious phenomena of nature. His limited knowledge could not explain the various natural operations by which he was surrounded, therefore he looked upon them as being mysterious and supernatural. His psychical being became active and inquiring, to satisfy which he created a system of gods which was founded on natural phenomena. At first, the gods of primitive man were, probably, few in number, and the chief god of all was the sun. Man early recognized the sun's importance in the economy of nature; this beautiful star, rising in the east in the morning, marching through the heavens during the day, and sinking behind the western horizon in the evening, must have been, to the awakening soul of man, a source of endless conjecture and debate. What was more natural than his making the sun the greatest god in his system of theogony? Man recognized in him the source of all life, and, when he arrived at an age when he could use abstract ideation in formulating his religion, he deified the life-giving
