91. Savage lore takes account of the powers of the separated soul only; the qualities and functions of the earthly incorporate soul are accepted as a part of the existing familiar order, and are not analyzed or discussed. It was different with the departed soul, which, because of its strangeness and mystery, was credited with extraordinary powers, and this part of savage science was gradually developed, through observation and inference, into an important system. In the search for causes, the Shade, its independent existence once established, came to be regarded as the agent in many procedures of which no probable account could otherwise be given.

92. The greatest activity of the departed soul is found in the earliest known period of culture, when it was not yet relegated to hades or to the sky, but dwelt on earth, either near its former habitation or in a distant region from which it might return. Its powers of movement and action are then held to be all that imagination can suggest. Such souls move through the air or under the ground, enter houses through obstacles impenetrable to the earthly man, pass into the human body, assume such shapes as pleases them. Divested of gross earthly bodies, they are regarded as raised above all ordinary limitations of humanity. Of these conceptions, that of the ghost's superhuman power of movement remains in the popular faith to the present day.

93. The practical question for the early man is the determination of the relation of departed souls to earthly life. Among savage tribes their attitude is sometimes friendly, sometimes unfriendly, more often the latter.195 To fear the unknown is a human instinct. Shades are looked on as aliens, and aliens are generally enemies. In particular, ghosts are conceived of as sometimes wandering about in search of food or warmth, or as cherishing enmity toward persons who had wronged them in their earthly life. They are supposed to be capable of inflicting disease or pain, and precautions are taken against them. Cases are reported of persons who killed themselves in order that, as ghosts, they might wreak vengeance on enemies.196 On the other hand, to the members of its own family the departed soul is sometimes held to be friendly, or not unfriendly, but among savages it is not thought of as a potent and valuable friend.

94. In the more advanced cults the functions of the departed souls become larger and more important. They are regarded as having the power of foretelling the future, and are consulted.197 They become guardian spirits, and a cult of souls arises.198 In some higher forms of religion (Judaism, Christianity, Islam) they are regarded as mediators between man and the deity, or as advocates for man in the heavenly court.
