“
But the bull-dog ant of Australia affords us the most extraordinary example of this kind; for if it is cut in two, a battle begins between the head and the tail. The head seizes the tail with its teeth, and the tail defends itself bravely by stinging the head; the battle may last for half an hour, until they die or are dragged away by the other ants. This contest takes place every time the experiment is tried . . . . Yunghahn relates that he saw in Java a plain, as far as the eye could reach, entirely covered with skeletons, and took it for a battle-field; they were, however, merely the skeletons of large turtles, . . . which come this way out of the sea to lay their eggs, and are then attacked by wild dogs who with their united strength lay them on their backs, strip off the small shell from the stomach, and devour them alive. But often then a tiger pounces upon the dogs . . . . For this these turtles are born . . . . Thus the will to live everywhere preys upon itself, and in different forms is its own nourishment, till finally the human race, because it subdues all the others, regards nature as a manufactory for its own use. Yet even the human race . . . reveals in itself with most terrible distinctness this conflict, this variance of the will with itself; and we find homo homini lupus.
