The life of the Kai people, according to Mr. Keysser, is dominated by their conception of the soul. That conception differs greatly from and is very much more extensive than ours. The Kai regards his reflection and his shadow as his soul or parts of it; hence you should not tread on a man's shadow for fear of injuring his soul. The soul likewise dwells in his heart, for he feels it beating. Hence if you give a native a friendly poke in the ribs, he protests, saying, "Don't poke me so; you might drive my soul out of my body, and then I should die." The soul moreover resides in the eye, where you may see it twinkling; when it departs, the eye grows dim and vacant. Moreover, the soul is in the foot as much as in the head; it lurks even in the spittle and the other bodily excretions. The soul in fact pervades the body just as warmth does; everything that a man touches he infects, so to say, with his soul; that mysterious entity exists in the very sound of his voice. The sorcerer catches a man's soul by his magic, shuts it up tight, and destroys it. Then the man dies. He dies because the sorcerer has killed his soul. Yet the Kai believes, whether consistently or not, that the soul of the dead man continues to live. He talks to it, he makes offerings to it, he seeks to win its favour in order that he may have luck in the chase; he fears its ill-will and anger; he gives it food to eat, liquor to drink, tobacco to smoke, and betel to chew. What could a reasonable ghost ask for more?[436]
Thus, according to Mr. Keysser, whose exposition I am simply reproducing, the Kai believes not in one nor yet in many souls belonging to each individual; he implicitly assumes that there are two different kinds of souls. One of these is the soul which survives the body at death; in all respects it resembles the man himself as he lived on earth, except that it has no body. It is not indeed absolutely incorporeal, but it is greatly shrunken and attenuated by death. That is why the souls of the dead are so angry with the living; they repine at their own degraded condition; they envy the full-blooded life which the living enjoy and which the dead have lost. The second kind of soul is distinguished by Mr. Keysser from the former as a spiritual essence or soul-stuff, which pervades the body as sap pervades the tree, and which diffuses itself like corporeal warmth over everything with which the body is brought into contact.[437] In these lectures we are concerned chiefly with the former kind of soul, which is believed to survive the death of the body, and which answers much more nearly than the second to the popular European conception of the soul. Accordingly in what follows we shall confine our attention mainly to it.
