"Father, mother, child, which express both the union of the sexes and de production of the being, can only be considered dependently on one another, and relatively to one another. A woman could exist without the existence of a man; but there is no mother if there is no father, nor a child without both of them. Each one of these ways of being presumes and recalls the other two; that is to say, they are relative. Considered thus, they are called relationships, in Latin, ratio; father, mother, child are persons, and their union forms the family. The union of the sexes, which is the foundation of all these relationships, is called marriage."
