The first is, that the idea is accepted as true, without the process of logical reasoning or inductive observation. In other words, what appears true to the individual is accepted by him as true, without further question. His dreams seem real to him; therefore they are real. What the tribe believes, he believes, no matter what his senses tell him. When an Australian Black is on a journey and fears being overtaken by the night, he will place a lump of clay in the forks of a tree, believing that thus he can arrest the motion of the sun and prolong the day. It is not a religious act, but a piece of natural science current in the tribe, which no experience will refute in their minds.[8] Just such a notion recurs among the Mandan Indians. Captain Clark observed near their villages upright poles fifteen or twenty feet long with bundles of female clothing tied to them. He asked what they signified, and one of the old men explained thus: “If you watch the sun closely, you will see that he stops for a short time just as he rises, and again at midday, and as he sets. The reason is that he rests a few moments to smoke in the lodges of three immortal women, and we offer them this clothing that they may be induced to say a kind word to him in our behalf. We were told by our ancestors not to forget this.”[9] The fact that the orb does not stop was of no consequence in the face of this tradition. The second trait is the extreme nervous susceptibility of savages. It is much higher than ours, although the contrary is often taught. Their emotions or feelings control their reasoning powers, and direct their actions. Neurotic diseases, especially of a contagious character, are very frequent among them, and they are far more prone than ourselves to yield to impressions upon their sensory organs. The traveller Castren relates that a sudden blow on the outside of a tent of the Samoyeds will sometimes throw the occupants into spasms; and the missionary Livingstone draws a touching picture of young slaves dying of “a broken heart,” when they heard the song and music of the villagers and could not join in the revelry.[10] These two traits, therefore, the acceptance of the idea as subjectively true, and the subordination of reason to the feelings, are the main features of the undeveloped mind. They are common in civilised conditions, but are universal in savagery. The question has often been considered whether the mental powers of the savage are distinctly inferior. This has been answered by taking the children of savages when quite young and bringing them up in civilised surroundings. The verdict is unanimous that they display as much aptitude for the acquisition of knowledge, and as much respect for the precepts of morality, as the average English or German boy or girl; but with less originality or “initiative.”
