It is very common for women to lament the indifference of husbands who were the most attentive and obedient of lovers. I have explained the cause of the defection. To secure happiness--or contentment, at least--in the marriage state, we must regard woman as our equal by nature, whatever superiority or inferiority she may possess by virtue of her mental or social education. We must not look _up_ to her, nor _down_ upon her, but straight _at_ her. We must not base our love for her upon supposed angelic qualities. If we desire to make her happy, and be happy ourselves, we must recognize her human origin in common with our own, and accept her physical inferiority as security for the continuance of our own love in all its normal strength. Of course there are grades in human nature. Some natures are more refined than others, from the effects of their surroundings and education. But the lover should recognize no degree higher than his own when he selects his mistress. Then, if hers proves higher than his, after marriage, he is delighted; if the same as his, he is satisfied. But suppose it should prove lower than his? Such a supposition is untenable in a marriage of mutual affection. A superior nature will never gravitate to an inferior one by the attraction of real love. There must be a natural sympathy; and sympathy is the rock upon which all true love is founded. Love never yet blended incompatible natures in marriage. Money often does--brute-insanity sometimes. You have probably concluded, by this time, my boy, that my ideas of the true Woman and Monsieur Michelet's views of "La Femme" are decidedly at variance. I have sufficient faith in the good sense of Woman to believe that she will give preference to my doctrine. If so, she will not translate "La Femme" as "Woman," but as "grisette," "lorette," or "camelia lady." To christen such a work "Woman," is to lay a snare for the Best of Her Sex, and catch the Weakest in it. The female who allows it to affect her may possibly make "a neatly-shod grisette," but never a good wife. It may be asked why I have made "Woman" the subject of this letter, and why I have adopted such a Frenchy style? Simply because there is no subject less understood, my boy, by the generality of young mankind; and because I deem it best to practice the doctrine of _similia similibus curantur_ (in style) while quarreling with Monsieur Michelet. Yours, sentimentally, ORPHEUS C. KERR. LETTER LXVII.
