370. The above illustrates the nature of the jealous fire into which polygamous conjugial love breaks out--a fire breaking out into anger and revenge, into anger in the case of the meek, and into revenge in the case of the fierce. This is because their love is natural and does not partake of what is spiritual. This follows from what was demonstrated in the chapter on Polygamy, namely, that polygamy is lasciviousness (no. 345), and that a polygamist, so long as he remains a polygamist, is natural and cannot become spiritual (no. 347). With natural monogamists, the jealous fire is different. Their love is not inflamed in this way against the women but against the violators. Against the latter it becomes anger, and against the former cold. Not so with polygamists. Moreover, the fire of their jealousy burns with vengeful fury. This also is among the reasons why after death the concubines and wives of polygamists are for the most part set free, and are assigned to unguarded women's apartments, there to make various things which pertain to women's work.
