In this topsy-turvy, crazy, illogical world, Man has made laws for himself. He has fenced himself round with them, mainly with the idea of keeping communities together, and gain for the strongest. No woman was consulted in the making of laws. And nine-tenths of the people who are daily obeying--or fighting against--Nature's laws, have no real opinion. Opinion means deduction, after weighing the matter, and deep thought upon it. They simply echo feeling, because for generations forbears have laid something down as an axiom. They do not investigate or weigh for themselves. The axiom of the forbears was, 'It is immoral to follow God's law, unless bound by man's law and a wedding ring.'
