There can be distinguished in the family four kinds of relations, whence spring four classes of duties: 1. The relations between the husband and wife. 2. The relations of parents to children. 3. The relations of children to parents. 4. The relations of children to each other. Whence conjugal duty, paternal or maternal duty, filial duty, and fraternal duty. To these four relations, there may be added a fifth: that of the head of a family to his servants. =125. Duties of marriage.=--The duties of marriage begin before marriage: they begin with the mutual choice of the man and the woman. For the woman, it usually happens, at least in our society [in France], that the choice is determined by the parents. The responsibility, then, falls upon them. Now, this choice should not be made lightly and foolishly. It should be determined by a serious and noble conception of the duties and end of marriage. "Marriage," our Code admirably says, "is an association between man and woman, to share the pleasures and bear in common the trials of life."[68] Marriage is, therefore, a compact entirely moral: it is not only a union of bodies or fortunes, it is a union of souls. Life in common and indissoluble, with all its possible accidents, is too heavy a burden to be left to chance. A man should think not only of his own happiness, but also of that of the woman whom he associates with his destiny; if he does not consider himself strong enough to fulfill toward her all the duties which such a connection imposes on him, he should not unite her to himself by indissoluble vows; if he does not think that he can love and respect her all through life, let him spare himself and her a life-long misery. We may see by this how important in conjugal union are a harmony of character, a just and mutual esteem, and an enlightened affection. To marry rashly and too hastily, and thus to risk future happiness, is already failing in a first duty. One should, therefore, not rely too implicitly upon indifferent or interested go-betweens.
