281. X. FOR VARIOUS REASONS, THESE ASSUMED CONJUGIAL SEMBLANCES WITH NATURAL MEN ARE FOUNDED IN PRUDENCE. In the case of two married partners of whom one is spiritual and the other natural, (by the spiritual we mean the one that loves spiritual things, and thereby is wise from the Lord, and by the natural, the one that loves only natural things, and thereby is wise from himself,) when they are united in marriage, conjugial love with the spiritual partner is heat, and with the natural is cold. It is evident that heat and cold cannot remain together, also that heat cannot inflame him that is in cold, unless the cold be first dispersed, and that cold cannot flow into him that is in heat, unless the heat be first removed: hence it is that inward love cannot exist between married partners, one of whom is spiritual and the other natural; but that a love resembling inward love may exist on the part of the spiritual partner, as was said in the foregoing article; whereas between two natural married partners no inward love can exist, since each is cold; and if they have any heat, it is from something unchaste; nevertheless such persons may live together in the same house, with separate minds (_animis_), and also assume looks of love and friendship towards each other, notwithstanding the disagreement of their minds (_mentes_): in such case, the external affections, which for the most part relate to wealth and possessions, or to honor and dignities, may as it were be kindled into a flame; and as such enkindling induces fear for their loss, therefore assumed conjugial semblances are in such cases necessities, which are principally those adduced below in articles XV.-XVII. The rest of the causes adduced with these may have somewhat in common with those relating to the spiritual man; concerning which see above, n. 280; but only in case the prudence with the natural man is founded in intelligence.
