A reciprocal restraint on the part of the husband is clearly of no importance whatever, so far as the first end of matrimony goes, the protection of the community from inferior births. It is no wrong to the State. But it does carry with it a variable amount of emotional offence to the wife; it may wound her pride and cause her violent perturbations of jealousy; it may lead to her neglect, her solitude and unhappiness, and it may even work to her physical injury. There should be an implication that it is not to occur. She has bound herself to the man for the good of the State, and clearly it is reasonable that she should look to the State for relief if it does occur. The extent of the offence given her is the exact measure of her injury; if she does not mind nobody minds, and if her self-respect does not suffer nothing whatever is lost to the world; and so it should rest with her to establish his misconduct, and, if she thinks fit, to terminate the marriage. A failure on either side to perform the elementary duties of companionship, desertion, for example, should obviously give the other mate the right to relief, and clearly the development of any disqualifying habit, drunkenness, or drug-taking, or the like, or any serious crime or acts of violence, should give grounds for a final release. Moreover, the modern Utopian State intervenes between the sexes only because of the coming generation, and for it to sustain restrictions upon conduct in a continually fruitless marriage is obviously to lapse into purely moral intervention. It seems reasonable, therefore, to set a term to a marriage that remains childless, to let it expire at the end of three or four or five unfruitful years, but with no restriction upon the right of the husband and wife to marry each other again. These are the fairly easy primaries of this question. We now come to the more difficult issues of the matter. The first of these is the question of the economic relationships of husband and wife, having regard to the fact that even in Utopia women, at least until they become mothers, are likely to be on the average poorer than men. The second is the question of the duration of a marriage. But the two interlock, and are, perhaps, best treated together in one common section. And they both ramify in the most complicated manner into the consideration of the general morale of the community. Section 5
