283. XII. THEY ARE FOR THE SAKE OF PRESERVING ORDER IN DOMESTIC AFFAIRS, AND FOR THE SAKE OF MUTUAL AID. Every house in which there are children, their instructors, and other domestics, is a small society resembling a large one. The latter also consists of the former, as a whole consists of its parts, and thereby it exists; and further, as the security of a large society depends on order, so does the security of this small society; wherefore as it behoves public magistrates to see and provide that order may exist and be preserved in a compound society, so it concerns married partners in their single society. But there cannot be this order if the husband and wife disagree in their minds (_animis_); for thereby mutual counsels and aids are drawn different ways, and are divided like their minds, and thus the form of the small society is rent asunder; wherefore to preserve order, and thereby to take care of themselves and at the same time of the house, or of the house and at the same time of themselves, lest they should come to hurt and fall to ruin, necessity requires that the master and mistress agree, and act in unity; and if, from the difference of their minds (_mentium_) this cannot be done so well as it might, both duty and propriety require that it be done by representative conjugial friendship. That hereby concord is established in houses for the sake of necessity and consequent utility, is well known. 284. XIII. THEY ARE FOR THE SAKE OF UNANIMITY IN THE CARE OF INFANTS AND THE EDUCATION OF CHILDREN. It is very well known that assumed conjugial semblances, which are appearances of love and friendship resembling such as are truly conjugial, exist with married partners for the sake of infants and children. The common love of the latter causes each married partner to regard the other with kindness and favor. The love of infants and children with the mother and the father unite as the heart and lungs in the breast. The love of them with the mother is as the heart, and the love towards them with the father is as the lungs. The reason of this comparison is, because the heart corresponds to love, and the lungs to the understanding; and love grounded in the will belongs to the mother, and love grounded in the understanding to the father. With spiritual men (_homines_) there is conjugial conjunction by means of that love grounded in justice and judgement; in justice, because the mother had carried them in her womb, had brought them forth with pain, and afterwards with unwearied care suckles, nourishes, washes, dresses, and educates them, (and in judgement, because the father provides for their instruction in knowledge, intelligence, and wisdom).
