374. That jealousy in certain cases arises from various mental weaknesses, is not unknown in the world; for there are jealous persons, who are continually thinking that their wives are unfaithful, and believe them to be harlots, merely because they hear or see them talk in a friendly manner with or about men. There are several vitiated affections of the mind which induce this weakness; the principal of which is a suspicious fancy, which if it be long cherished, introduces the mind into societies of similar spirits, from whence it cannot without difficulty be rescued; it also confirms itself in the body, by rendering the serum, and consequently the blood, viscous, tenacious, thick, slow, and acrid, a defect of strength also increases it; for the consequence of such defect is, that the mind cannot be elevated from its suspicious fancies; for the presence of strength elevates, and its absence depresses, the latter causing the mind to sink, give way, and become feeble; in which case it immerses itself more and more in the above fancy, till it grows delirious, and thence takes delight in quarrelling, and, so far as is allowable, in abuse.
375. There are also several countries, which more than others labor under this weakness of jealousy: in these the wives are imprisoned, are tyrannically shut out from conversation with men, are prevented from even looking at them through the windows, by blinds drawn down, and are terrified by threats of death if the cherished suspicion shall appear well grounded; not to mention other hardships which the wives in those countries suffer from their jealous husbands. There are two causes of this jealousy; one is, an imprisonment and suffocation of the thoughts in the spiritual things of the church; the other is, an inward desire of revenge. As to the first cause,—the imprisonment and suffocation of the thoughts in the spiritual things of the church, its operation and effect may be concluded from what has been proved above,—that everyone has conjugial love according to the state of the church with him, and as the church is from the Lord, that that love is solely from the Lord, n. [130], [131]; when therefore, instead of the Lord, living and deceased men are approached and invoked, it follows, that the state of the church is such that conjugial love cannot act in unity with it; and the less so while the mind is terrified into that worship by the threats of a dreadful prison: hence it comes to pass, that the thoughts, together with the expressions of them in conversation, are violently seized and suffocated; and when they are suffocated, there is an influx of such things as are either contrary to the church, or imaginary in favor of it; the consequence of which is, heat in favor of harlots and cold towards a married partner; from which two principles prevailing together in one subject, such an unconquerable fire of jealousy flows forth. As to the second cause,—the inward desire of revenge, this altogether checks the influx of conjugial love, and swallows it up, and changes the delight thereof, which is celestial, into the delight of revenge, which is infernal; and the proximate determination of this latter is to the wife. There is also an appearance, that the unhealthiness of the atmosphere, which in those regions is impregnated with the poisonous exhalations of the surrounding country, is an additional cause.
376. XI. IN SOME INSTANCES THERE IS NOT ANY JEALOUSY; AND THIS ALSO FROM VARIOUS CAUSES. There are several causes of there being no jealousy, and of its ceasing. The absence of jealousy is principally with those who make no more account of conjugial than of adulterous love, and at the same time are so void of honorable feeling as to slight the reputation of a name: they are not unlike married pimps. There is no jealousy likewise with those who have rejected it from a confirmed persuasion that it infests the mind, and that it is useless to watch a wife, and that to do so serves only to incite her, and that therefore it is better to shut the eyes, and not even to look through the key-hole, lest any thing should be discovered. Some have rejected jealousy on account of the reproach attached to the name, and under the idea that any one who is a real man, is afraid of nothing: some have been driven to reject it lest their domestic affairs should suffer, and also lest they should incur public censure in case the wife was convicted of the disorderly passion of which she is accused. Moreover jealousy passes off into no jealousy with those who grant license to their wives, either from a want of ability, or with a view to the procreation of children for the sake of inheritance, also in some cases with a view to gain, and so forth. There are also disorderly marriages, in which, by mutual consent, the licence of unlimited amour is allowed to each party, and yet they are civil and complaisant to each other when they meet.
377. XII. THERE IS A JEALOUSY ALSO IN REGARD TO CONCUBINES, BUT NOT SUCH AS IN REGARD TO WIVES. Jealousy in regard to wives originates in a man's inmost principles; but jealousy in regard to concubines originates in external principles; they therefore differ in kind. The reason why jealousy in regard to wives originates in inmost principles is, because conjugial love resides in them: the reason why it resides there is, because marriage from the eternity of its compact established by covenant, and also from an equality of right, the right of each party being transferred to the other, unites souls, and lays a superior obligation on minds: this obligation and that union, once impressed, remain inseparable, whatever be the quality of the love afterwards, whether it be warm or cold. Hence it is that an invitation to love coming from a wife chills the whole man from the inmost principles to the outermost; whereas an invitation to love coining from a concubine has not the same effect upon the object of her love. To jealousy in regard to a wife is added the earnest desire of reputation with a view to honor; and there is no such addition to jealousy in regard to a concubine. Nevertheless both kinds of jealousy vary according to the seat of the love received by the wife and by the concubine; and at the same time according to the state of the judgment of the man receiving it.
378. XIII. JEALOUSY LIKEWISE EXISTS AMONG BEASTS AND BIRDS. That it exists among wild beasts, as lions, tigers, bears, and several others, while they have whelps, is well known; and also among bulls, although they have not calves: it is most conspicuous among dung-hill cocks, who in favor of their hens fight with their rivals even to death: the reason why the latter have such jealousy is, because they are vain-glorious lovers, and the glory of that love cannot endure an equal; that they are vain-glorious lovers, above every genus and species of birds, is manifest from their gestures, nods, gait, and tone of voice. That the glory of honor with men, whether lovers or not, excites, increases, and sharpens jealousy, has been confirmed above.
