*The inviolableness and permanence of marriage* are so absolutely essential to the stability and well-being of families, as to be virtually a part of the law of nature. The young of other species have but a very brief period of dependence; while the human child advances very slowly toward maturity, and for a considerable portion of his life needs, for both body and mind, support, protection, and guidance from his seniors. The separation of parents by other causes than death might leave it an unsolvable question, to which of them the custody of their children appertained; and in whichever way they were disposed of, their due nurture and education would be inadequately secured. The children might be thrown upon the mother’s care, while the means of supporting them belonged exclusively to the father. Or in the father’s house they might suffer for lack of a mother’s personal attention and services; while if he contracted a new matrimonial connection, the children of the previous marriage could hardly fail of neglect, or even of hatred and injury, from their mother’s successful rival, especially if she had children of her own.(12) The life-tenure of the marriage-contract contributes equally to the *happiness of the conjugal relation*, in the aggregate. There are, no doubt, individual cases of hardship, in which an utter and irremediable incompatibility of temper and character makes married life a burden and a weariness to both parties. But the cases are much more numerous, in which discrepancies of taste and disposition are brought by time and habit into a more comprehensive harmony, and the husband and wife, because unlike, become only the more essential, each to the other’s happiness and welfare. Where there is sincere affection, there is little danger that lapse of years in a permanent marriage will enfeeble it; while, were the contract voidable at will, there might be after marriage, as often before marriage, a series of attachments of seemingly equal ardor, each to be superseded in its turn by some new attraction. Where, on the other hand, the union is the result, not of love, but of mutual esteem and confidence, aided by motives of convenience, the very possibility of an easy divorce would render each party captious and suspicious, so that confidence could be easily shaken, and esteem easily impaired; while in those who expect always to have a common home the tendency is to those habits of mutual tolerance, accommodation, and concession, through which confidence and esteem ripen into sincere and lasting affection.
