But this discussion would take us far from our subject, if it led us to examine, in all its details, the vast improvement in morals which doubtless will distinguish twentieth century France; for morals are reformed only very gradually! Is it not necessary, in order to produce the slightest change, that the most daring dreams of the past century become the most trite ideas of the present one? We have touched upon this question merely in a trifling mood, for the purposes of showing that we are not blind to its importance, and of bequeathing also to posterity the outline of a work, which they may complete. To speak more accurately there is a third work to be composed; the first concerns courtesans, while the second is the physiology of pleasure! "When there are ten of us, we cross ourselves." In the present state of our morals and of our imperfect civilization, a problem crops up which for the moment is insoluble, and which renders superfluous all discussion on the art of choosing a wife; we commend it, as we have done all the others, to the meditation of philosophers. PROBLEM. It has not yet been decided whether a wife is forced into infidelity by the impossibility of obtaining any change, or by the liberty which is allowed her in this connection. Moreover, as in this work we pitch upon a man at the moment that he is newly married, we declare that if he has found a wife of sanguine temperament, of vivid imagination, of a nervous constitution or of an indolent character, his situation cannot fail to be extremely serious. A man would find himself in a position of danger even more critical if his wife drank nothing but water [see the Meditation entitled _Conjugal Hygiene_]; but if she had some talent for singing, or if she were disposed to take cold easily, he should tremble all the time; for it must be remembered that women who sing are at least as passionate as women whose mucous membrane shows extreme delicacy. Again, this danger would be aggravated still more if your wife were less than seventeen; or if, on the other hand, her general complexion were pale and dull, for this sort of woman is almost always artificial. But we do not wish to anticipate here any description of the terrors which threaten husbands from the symptoms of unhappiness which they read in the character of their wives. This digression has already taken us too far from the subject of boarding schools, in which so many catastrophes are hatched, and from which issue so many young girls incapable of appreciating the painful sacrifices by which the honest man who does them the honor of marrying them, has obtained opulence; young girls eager for the enjoyments of luxury, ignorant of our laws, ignorant of our manners, claim with avidity the empire which their beauty yields them, and show themselves quite ready to turn away from the genuine utterances of the heart, while they readily listen to the buzzing of flattery.
