So much for the preliminary conditions of matrimony. For those men and women who chose to ignore these conditions and to achieve any sort of union they liked the State would have no concern, unless offspring were born illegitimately. In that case, as we have already suggested, it would be only reasonable to make the parents chargeable with every duty, with maintenance, education, and so forth, that in the normal course of things would fall to the State. It would be necessary to impose a life assurance payment upon these parents, and to exact effectual guarantees against every possible evasion of the responsibility they had incurred. But the further control of private morality, beyond the protection of the immature from corruption and evil example, will be no concern of the State's. When a child comes in, the future of the species comes in; and the State comes in as the guardian of interests wider than the individual's; but the adult's private life is the entirely private life into which the State may not intrude. Now what will be the nature of the Utopian contract of matrimony? From the first of the two points of view named above, that of parentage, it is obvious that one unavoidable condition will be the chastity of the wife. Her infidelity being demonstrated, must at once terminate the marriage and release both her husband and the State from any liability for the support of her illegitimate offspring. That, at any rate, is beyond controversy; a marriage contract that does not involve that, is a triumph of metaphysics over common sense. It will be obvious that under Utopian conditions it is the State that will suffer injury by a wife's misconduct, and that a husband who condones anything of the sort will participate in her offence. A woman, therefore, who is divorced on this account will be divorced as a public offender, and not in the key of a personal quarrel; not as one who has inflicted a private and personal wrong. This, too, lies within the primary implications of marriage. Beyond that, what conditions should a marriage contract in Utopia involve?
