259. (23) Of these incidental reasons for coldness, a fourth is the man's thinking of his wife day and night that she wants to, and conversely the wife's thinking of her husband that he does not want to. Except to observe that the first is a reason for coldness in men, and that the second is a reason for love's ceasing in wives, we pass this by without discussion. For among the things known to husbands who explore secrets relating to conjugial love is the fact that a man is chilled to the bone if, at the sight of his wife by day or at her side by night, he thinks of her that she has the desire or wants to, and conversely, that a wife loses her love for her husband if she thinks of him that he is able and does not want to. We include these observations as well in order to make this work complete and not omit anything from our treatment of the delights of wisdom relating to conjugial love.
