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.
