373. X. THAT WITH MARRIED PARTNERS WHO DO NOT LOVE EACH OTHER, JEALOUSY IS DUE TO MANY CAUSES, AND WITH SOME TO VARIOUS KINDS OF MENTAL SICKNESS. The reasons why married partners who do not mutually love each other are also jealous are principally, honor from potency, fear of dishonoring one's name and also that of one's wife, and dread lest one's domestic affairs be ruined. That men have honor from potency, that is, that from this they wish to be accounted as great men, is well known; for so long as they have this honor, they are as though raised up in their own mind and not shamefaced among men and women. Moreover, to this honor is attached the attribute of bravery, and therefore military officers have it more than others. As to fear of dishonoring one's name and that of one's wife, this makes one with the preceding reason; added to which is the fact that cohabitation with a harlot, and having a brothel in the home, are infamous. That jealousy exists with some lest their domestic affairs be ruined, is because the husband is so greatly disgraced, and mutual duties and services are done away with. With some, however, this jealousy ceases in time and becomes nonexistent, and with some it turns into a mere simulation of love.
