377. XII. THAT THERE IS JEALOUSY ALSO FOR MISTRESSES, BUT IT IS NOT OF THE SAME NATURE AS FOR WIVES. With man, jealousy for wives springs from inmosts, but jealousy for mistresses from outmosts. Therefore they differ in kind. That jealousy for wives springs from inmosts is because in inmosts resides conjugial love; and it resides there because, by reason of its eternal pact established by covenant, and also by reason of equality of right, in that what belongs to the one partner belongs to the other, marriage unites souls and binds minds together more deeply. This binding and union, once imposed, remains unbroken, whatsoever be the later love between them, whether warm or cold.  Thence it is, that invitation to love by a wife chills the whole man from inmosts to ultimates, while invitation to love by a mistress does not thus chill the lover. To jealousy for a wife is added ambition for a good name for the sake of honor, while jealousy for a mistress lacks this accessory. Yet both these jealousies vary according to the seat of the love received from the wife, and of that received from the mistress, and at the same time, according to the state of the judgment of the man receiving it.
