On the other hand, that the wife should be bound indissolubly by the marriage-tie to an unfaithful husband (or _vice versa_), is a violation of the right of wife (or husband, as the case may be), because on the one hand the restraint which makes her liable to be used physically as the instrument of the husband's pleasures, when there is no longer reciprocal devotion between them, is a restraint which (except in peculiar cases) renders moral elevation impossible; and on the other, she is prevented from forming such a true marriage as would be, according to ordinary rules, the condition of the realisation of her moral capacities. Though the husband's right to divorce from an unfaithful wife has been much more thoroughly recognised than the wife's to divorce from an unfaithful husband, he would be in fact less seriously wronged by the inability to obtain a divorce, for it is only the second of the grounds just stated that fully applies to him. The rights of the children do not seem so plainly concerned in the dissolution of a marriage to which husband or wife has been unfaithful. In some cases the best chance for them might seem to lie in the infidelities being condoned and an outward family peace re-established. But that their rights are violated by the infidelity itself is plain. In the most definite way it detracts from their possibilities of goodness. Without any consent on their part, quite independently of any action of their own will, they are placed by it in a position which tends--though special grace may counteract it--to put the higher kinds of goodness beyond their reach. 243. These considerations suggest some further questions which may be discussed under the following heads. (1) If infidelity in marriage is a violation of rights in the manner stated, and if (as it must be) it is a wilful and knowing violation, why is it not treated as a crime, and, like other such violations of rights, punished by the state in order to the better maintenance of rights? (2) Should any other reason but the infidelity of husband or wife be allowed for the legal dissolution of the marriage-tie? (3) How are the rights connected with marriage related to the morality of marriage?
