509. III. THAT THIS LUST UTTERLY ANNIHILATES CONJUGIAL LOVE WITH THEM is because the lust is utterly opposed to conjugial love, and so opposed that it not merely rends it but, as it were, grinds it to powder and thus annihilates it. Conjugial love is love directed to one of the sex, but this lust does not stop with one but an hour or a day later is as intense with cold for her as it had previously been hot. And because the cold is a loathing, by forced cohabitation and living together this loathing piles up even to disgust, and conjugial love is so far consumed that no remnant is left. It can be seen from the above that this lust is deadly to conjugial love; and since conjugial love makes the inmost life with man, that it is deadly to his life; also that, by successive interceptions and closings of the interiors of the mind, it finally becomes cutaneous, and thus merely alluring, the faculty of understanding, that is, rationality, nevertheless remaining.
