34. (19) Conjugial love depends upon the wife's love, and such too is the husband's love reciprocally; the wife's love does not depend on her husband's love. The reason is that just as the will acts on the understanding, good acts on truth; that is why it is said that a man ought to cleave to his wife. The reverse is true of those who are not in conjugial love.

If man closes up the middle natural degree, which corresponds to the middle spiritual, he becomes, with respect to love, like a fox, and with respect to intellectual sight, like a bird of the evening. People in self-derived prudence are like foxes and wolves.
