_The moment when first the conqueror spared his victim in order permanently to exploit him in productive work, was of incomparable historical importance. It gave birth to nation and state, to right and the higher economics, with all the developments and ramifications which have grown and which will hereafter grow out of them._ The root of everything human reaches down into the dark soil of the animal--love and art, no less than state, justice and economics. Still another tendency knots yet more closely these psychic relations. To return to the comparison of the herdsman and the bear, there are in the desert, beside the bear who guards the bees, other bears who also lust after honey. But our tribe of herdsmen blocks their way, and protects its beehives by force of arms. The peasants become accustomed, when danger threatens, to call on the herdsmen, whom they no longer regard as robbers and murderers, but as protectors and saviors. Imagine the joy of the peasants when the returning band of avengers brings back to the village the looted women and children, with the enemies’ heads or scalps. These ties are no longer threads, but strong and knotted bands. Here is one of the principal forces of that “integration,” whereby in the further development, those originally not of the same blood, and often enough of different groups speaking different languages, will in the end be welded together into _one_ people, with _one_ speech, _one_ custom, and _one_ feeling of nationality. This unity grows by degrees from common suffering and need, common victory and defeat, common rejoicing and common sorrow. A new and vast domain is open when master and slave serve the same interests; then arises a stream of sympathy, a sense of common service. Both sides apprehend, and gradually recognize, each other’s common humanity. Gradually the points of similarity are sensed, in place of the differences in build and apparel, of language and religion, which had heretofore brought about only antipathy and hatred. Gradually they learn to understand one another, first through a common speech, and then through a common mental habit. The net of the psychical inter-relations becomes stronger. In this second stage of the formation of states, the ground work, in its essentials, has been mapped out. No further step can be compared in importance to the transition whereby the bear becomes a bee-keeper. For this reason, short references must suffice.
