Women samurai who are married, my double told me, must bear children—if they are to remain married as well as in the order—before the second period for terminating a childless marriage is exhausted. I failed to ask for the precise figures from my double at the time, but I think it is beyond doubt that it is from samurai mothers of the Greater or Lesser Rule that a very large proportion of the future population of Utopia will be derived. There is one liberty accorded to women samurai which is refused to men, and that is to marry outside the Rule, and women married to men not under the Rule are also free to become samurai. Here, too, it will be manifest there is scope for novels and the drama of life. In practice, it seems that it is only men of great poietic distinction outside the Rule, or great commercial leaders, who have wives under it. The tendency of such unions is either to bring the husband under the Rule, or take the wife out of it. There can be no doubt that these marriage limitations tend to make the samurai something of an hereditary class. Their children, as a rule, become samurai. But it is not an exclusive caste; subject to the most reasonable qualifications, anyone who sees fit can enter it at any time, and so, unlike all other privileged castes the world has seen, it increases relatively to the total population, and may indeed at last assimilate almost the whole population of the earth.
