But the side of her character which strikes us most forcibly at this distance of time is the emotional. The personal charm which is always so large a factor in social success is of too subtle a quality to be caught in words. The most vivid portrait leaves a divine something to be supplied by the imagination, and the fascination of eloquence is gone with the flash of the eye, the modulation of the voice, or some fleeting grace of manner. But passion writes itself out in indelible characters, especially when it is a rare and spontaneous overflow from the heart of a man or woman of genius, whose emotions readily crystallize into form.
Her friendship for d'Alembert, loyal and devoted as it was, seems to have been without illusions. It is true she had cast aside every other consideration to nurse him through a dangerous illness, and as soon as he was able to be removed, he had taken an apartment in the house where she lived, which he retained until her death. But he was not rich, and marriage was not to be thought of. On this point we have his own testimony. "The one to whom they marry me in the gazettes is indeed a person respectable in character, and fitted by the sweetness and charm of her society to render a husband happy," he writes to Voltaire;
"but she is worthy of an establishment better than mine, and there is between us neither marriage nor love, but mutual esteem, and all the sweetness of friendship. I live actually in the same house with her, where there are besides ten other tenants; this is what has given rise to the rumor." His devotion through so many years, and his profound grief at her loss, as well as his subsequent words, leave some doubt as to the tranquillity of his heart, but the sentiments of Mlle. de Lespinasse seem never to have passed the calm measure of an exalted and sympathetic friendship. It was remarked that he lost much of his prestige, and that his society which had been so brilliant, became infinitely more miscellaneous and infinitely less agreeable after the death of the friend whose tact and finesse had so well served his ambition.
Not long after leaving Mme. du Deffand she met the Marquis de Mora, a son of the Spanish ambassador, who became a constant habitue of her salon. Of distinguished family and large fortune, brilliant, courtly, popular, and only twenty-four, he captivated at once the fiery heart of this attractive woman of thirty-five.
It seems to have been a mutual passion, as during one brief absence of ten days he wrote her twenty-two letters. But his family became alarmed and made his delicate health a pretext for recalling him to Spain. Her grief at the separation enlisted the sympathy of d'Alembert. At her request he procured from his physician a statement that the climate of Madrid would prove fatal to M. de Mora, whose health had steadily failed since his return home, and that if his friends wished to save him they must lose no time in sending him back to Paris. The young man was permitted to leave at once, but he died en route at Bordeaux.
In the meantime Mlle. de Lespinasse, sad and inconsolable, had met M. Guibert, a man of great versatility and many accomplishments, whose genius seems to have borne no adequate fruit. We hear of him later through the passing enthusiasm of Mme. de Stael, who in her youth, made a pen-portrait of him, sufficiently flattering to account in some degree for the singular passion of which he became the object. Mlle. de Lespinasse was forty. He was twenty-nine, had competed for the Academie Francaise, written a work on military science, also a national tragedy which was still unpublished. She was dazzled by his brilliancy, and when she fathomed his shallow nature, as she finally did, it was too late to disentangle her heart. He was a man of gallantry, and was flattered by the preference of a woman much in vogue, who had powerful friends, influence at the Academy, and the ability to advance his interest in many ways.
He clearly condescended to be loved, but his own professions have little of the true ring.
