Trace it up. Our ape-like and arboreal ancestors entered upon the first of many short cuts. To crack a marrow-bone with a rock was the act which fathered the tool, and between the cracking of a marrow-bone and the riding down town in an automobile lies only a difference of degree. The one is crudely artificial, the other consummately artificial. That is all. There have been improvements. The first inventors grasped that truthful paradox, "the longest way round is the shortest way home," and forsook the direct pursuit of happiness for the indirect pursuit of happiness. If the happiness of a savage depended upon his crossing an extensive body of water, he did not directly proceed to swim it, but turned his back upon it, selected a tree from the forest, shaped it with his rude tools and hollowed it out with fire, then launched it in the water and paddled toward where his happiness lay. Now concerning love. In the state of nature it is a brutal passion, nothing more. There is no romance attached. But life creeps upward, and the gregarious human forms social groups the like of which never existed before. Consider the family group, for instance. Such a group becomes in itself an entity. By means of the group man is better enabled to pursue happiness. But to maintain the group it must be regulated; so man formulates rules, codes, dim ethical laws for the conduct of the group members. Sexual ties are made less promiscuous and more orderly. A greater privacy is observed. And out of order and privacy spring respect and sacredness.
