“Law of Battle. — With savages, for instance the Australians, the women are the constant cause of war both between members of the same tribe and between distinct tribes. So no doubt it was in ancient times; "nam fuit ante Helenam mulier teterrima belli causa." With some of the North American Indians, the contest is reduced to a system. … With the Guanas of South America, Azara states that the men rarely marry till twenty years old or more, as before that age they cannot conquer their rivals.”

Context: These are the Galla and Gaga tribes, which, as the most savage and most barbarous of conquerors, have repeatedly descended upon the coasts since the year 1542, pouring forth from the interior and inundating the whole country. These look upon man in the strength of his consciousness as too exalted to be capable of being killed by anything so obscure as the power of nature. What therefore takes place is, that sick people, in whose case magic has proved ineffectual, are put to death by their friends. In the same way the wild tribes of North America too killed their aged who had reached decrepitude, the meaning of which is unmistakable, namely, that man is not to perish by means of nature, but is to have due honour rendered to him at human hands. There is another people again who have the belief that everything would go to ruin if their high-priest were to die a natural death. He is therefore executed as soon as ever he becomes ill and weak; if a high-priest should notwithstanding die of some disease, they believe that some other person killed him by means of magic, and the magicians have to ascertain who the murderer was, when he is at once made away with. On the death of a king in particular, many persons are killed: according to a missionary of older days, it is the devil of the king who is slain. Such, then, is the very first form of religion, which cannot indeed as yet be properly called religion.
