Robert Dale Owen--the virtuous and justly revered author of "Moral Physiology;" a man so respected in his adopted country, the United States of America, that he was elected as one of its senators, and was appointed American ambassador at the Court of Naples--Robert Dale Owen, in a letter to Thomas Whittemore, editor of the Boston Trumpet, May, 1831, deals as follows with the contract of marriage:-- "I do not think it virtuous or rational in a man and woman solemnly to swear that they will love and honour each other until death part them. First, because if affection or esteem on either side should afterwards cease (as, alas! we often see it cease), the person who took the marriage-oath has perjured himself; secondly, because I have observed that such an oath, being substituted for the noble and elevating principle of moral obligation, has a tendency to weaken that principle. "You will probably ask me whether I should equally object to a solemn promise to live together during life whatever happens. I do not think this _equally_ objectionable, because it is an explicit promise possible to be kept; whereas the oath to love until death, may become impossible of fulfilment. But still I do not approve even this possible promise; and I will give you the reasons why I do not. "That a man and woman should occupy the same house, and daily enjoy each other's society, so long as such an association gives birth to virtuous feelings, to kindness, to mutual forbearance, to courtesy, to disinterested affection, I consider right and proper. That they should continue to inhabit the same house and to meet daily, in case such intercourse should give birth to vicious feelings, to dislike, to ill temper, to scolding, to a carelessness of each other's comfort and a want of respect for each other's feelings,--this I consider, _when the two individuals alone are concerned_, neither right nor proper; neither conducive to good order nor to virtue. I do not think it well, therefore, to promise, at all hazards, to live together for life. "Such a view may be offensive to orthodoxy, but surely, surely it is approved by common sense. Ask yourself, sir, who is--who can be the gainer--the man, the woman, or society at large--by two persons living in discord rather than parting in peace, as Abram and Lot did when their herdsmen could not agree. We have temptations enough already to ill humour in the world, without expressly creating them for ourselves; and of all temptations to that worst of petty vices, domestic bickering, can we suppose one more strong or more continually active than a forced association in which the heart has no share? Do not the interests of virtue and good order, then, imperiously demand (as the immortal author of 'Paradise Lost' argued, in his celebrated work 'On Divorce,') that the law should abstain from perpetuating any association, after it has become a daily source of vice?
