One of the most fertile sources of human misery, then, arises from persons uniting in marriage, whose tempers, talents and dispositions do not harmonize. If it be true that natural talents and dispositions are connected by the Creator with particular constitutions of the parents, it is obviously one of his institutions, that these constitutions should be most seriously taken into the calculation in forming a compact for life. The Creator, having formed such ordinances in the unchangeable arrangements of nature, as to confer happiness, when they are discovered and observed, and misery, when they are unknown or unobserved, it is obviously our best wisdom to investigate and respect them. If individuals, after this truth reaches their conviction should go on, in imitation of the common example, to form reckless connexions, which can only eventuate in sorrow, it is obvious that they must do so either from contempt of the effects of this influence upon the happiness of domestic life, and a secret belief, that they may in some way evade its consequences, or from the predominance of avarice, or some other animal feeling, precluding them from yielding obedience to what they see to be an institution of the Creator. At the first aspect of this subject three alternatives are presented, one of which, it should seem, must have a determining power upon the offspring. Either, in the first place, the corporeal and mental constitution, which the parents themselves inherit at birth, are transmitted so absolutely, as that the children are exact copies of the parents, without variation or modification, sex following sex; or, in the second place, the inherent qualities of the father and mother combine, and are transmitted in a modified form to the offspring; or, thirdly, the qualities of the children are determined jointly by the constitution of the parents, and the faculties and temperaments, which predominated in power and energy at the particular period, when the organic existence of the child commenced. If these views are correct, and if a man and woman about to marry, have not only their own domestic happiness but that of five or more human beings depending on their attention to considerations essentially the same as the foregoing, how differently ought this contract to be viewed from the common aspect, which it presents to persons assuming its solemn stipulations! Yet it is astonishing, to what extent pecuniary and other minor considerations will induce men to investigate and observe the natural laws; and how small an influence moral and rational considerations exert upon this most important of all earthly connexions. I cannot forbear, under this head, quoting entire another passage from the author, from whom I have substantially drawn many of the foregoing observations.
