And now will burst forth from her those pleasantries at which you will be the first to laugh and those reflections which will startle you by their profundity; now you will see sudden changes of mood and the caprices of a mind which hesitates. At times she will exhibit extreme tenderness, as if she repented of her thoughts and her projects; sometimes she will be sullen and at cross-purposes with you; in a word, she will fulfill the _varium et mutabile femina_ which we hitherto have had the folly to attribute to the feminine temperament. Diderot, in his desire to explain the mutations almost atmospheric in the behavior of women, has even gone so far as to make them the offspring of what he calls _la bete feroce_; but we never see these whims in a woman who is happy. These symptoms, light as gossamer, resemble the clouds which scarcely break the azure surface of the sky and which they call flowers of the storm. But soon their colors take a deeper intensity. In the midst of this solemn premeditation, which tends, as Madame de Stael says, to bring more poetry into life, some women, in whom virtuous mothers either from considerations of worldly advantage of duty or sentiment, or through sheer hypocrisy, have inculcated steadfast principles, take the overwhelming fancies by which they are assailed for suggestions of the devil; and you will see them therefore trotting regularly to mass, to midday offices, even to vespers. This false devotion exhibits itself, first of all in the shape of pretty books of devotion in a costly binding, by the aid of which these dear sinners attempt in vain to fulfill the duties imposed by religion, and long neglected for the pleasures of marriage. Now here we will lay down a principle, and you must engrave it on your memory in letters of fire. When a young woman suddenly takes up religious practices which she has before abandoned, this new order of life always conceals a motive highly significant, in view of her husband’s happiness. In the case of at least seventy-nine women out of a hundred this return to God proves that they have been inconsistent, or that they intend to become so. But a symptom more significant still and more decisive, and one that every husband should recognize under pain of being considered a fool, is this: At the time when both of you are immersed in the illusive delights of the honeymoon, your wife, as one devoted to you, would constantly carry out your will. She was happy in the power of showing the ready will, which both of you mistook for love, and she would have liked for you to have asked her to walk on the edge of the roof, and immediately, nimble as a squirrel, she would have run over the tiles. In a word, she found an ineffable delight in sacrificing to you that _ego_ which made her a being distinct from yours. She had identified herself with your nature and was obedient to that vow of the heart, _Una caro_.
