The question was discussed by Ninon and her "Birds" for several days without reaching an opinion that was in any manner satisfactory. It was therefore resolved to consult Saint-Evremond, who was living in exile in England. After writing him all the particulars, and the discussions that had been held with opinions pro and con, he sent the following letter in reply, which is unanswerable upon the subject. Moreover, it contains lessons that should be carefully studied and well learned by all loving hearts, who desire to maintain their early affection for each other during life. The letter is a masterpiece of the philosophy of love, and it is remarkable, in that it develops traits in human nature upon the subject of love and marriage, which are overlooked in questions applicable to the relations between the sexes, and that are so often strained to the breaking point. Indeed, it gives clues to a remedy which can not fail to effect a cure. * * * * * My opinion is exactly in line with yours, Mademoiselle; it is not always, as some think, hymen or the possession of the loved object which of itself destroys love; the true source of the dissatisfaction that follows exists in the unintelligent manner of economizing the sentiments, a too complete, too easy, and too prolonged possession. When we have yielded to the transports of a passion without reserve, the tremendous shock to the soul can not fail quickly to leave it in a profound solitude. The heart finds itself in a void which alarms and chills it. We vainly seek outside of ourselves, the cause of the calm which follows our fits of passion; we do not perceive that an equal and more enduring happiness would have been the fruit of moderation. Make an exact analysis of what takes place within you when you desire anything. You will find that your desires are nothing but curiosity, and this curiosity, which is one of the forces of the heart, satisfied, our desires vanish. Whoever, therefore, would hold a spouse or a lover should leave him something to be desired; something new should be expected every day for the morrow. Diversify his pleasures, procure for him the charm of variety in the same object, and I will vouch for his perseverance in fidelity. I confess, however, that hymen, or what you call your "defeat," is, in an ordinary woman, the grave of love. But then it is less upon the lover that the blame falls, than upon her who complains of the cooling of the passion; she casts upon the depravity of the heart what is due to her own unskillfulness, and her lack of economy. She has expended in a single day everything that might keep alive the inclination she had excited. She has nothing more to offer to the curiosity of her lover, she becomes always the same statue; no variety to be hoped for, and her lover knows it well.
