The Marriage compact is the most important feature of the domestic state on which the observer can fix his attention. If he be a thinker, he will not be surprised at finding much imperfection in the marriage state wherever he goes. By no arrangements yet attempted have purity of morals, constancy of affection, and domestic peace been secured to any extensive degree in society. Almost every variety of method is still in use, in one part of the world or another. The primitive custom of brothers marrying sisters still subsists in some Eastern regions. Polygamy is very common there, as every one knows. In countries which are too far advanced for this, every restraint of law, all sanction of opinion, has been tried to render the natural method,--the restriction of one husband to one wife,--successful, and therefore universal and permanent. Law and opinion have, however, never availed to anything like complete success. Even in thriving young countries, where no considerations of want, and few of ambition, can interfere with domestic peace,--where the numbers are equal, where love has the promise of a free and even course, and where religious sentiment is directed full upon the sanctity of the marriage state,--it is found to be far from pure. In almost all countries, the corruption of society in this department is so deep and wide-spreading, as to vitiate both moral sentiment and practice in an almost hopeless degree. It neutralizes almost all attempts to ameliorate and elevate the condition of the race.--There must be something fearfully wrong where the general result is so unfortunate as this. As in most other cases of social suffering, the wrong will be found to lie less in the methods ordained and put in practice, than in the prevalent sentiment of society, out of which all methods arise.
