It was thus that my beloved Henriette would often make me spend delightful hours, talking philosophic sentiment. Her logic was better than that of Cicero in his Tusculan Disputations, but she admitted that such lasting felicity could exist only between two beings who lived together, and loved each other with constant affection, healthy in mind and in body, enlightened, sufficiently rich, similar in tastes, in disposition, and in temperament. Happy are those lovers who, when their senses require rest, can fall back upon the intellectual enjoyments afforded by the mind! Sweet sleep then comes, and lasts until the body has recovered its general harmony. On awaking, the senses are again active and always ready to resume their action. The conditions of existence are exactly the same for man as for the universe, I might almost say that between them there is perfect identity, for if we take the universe away, mankind no longer exists, and if we take mankind away, there is no longer an universe; who could realize the idea of the existence of inorganic matter? Now, without that idea, ‘nihil est’, since the idea is the essence of everything, and since man alone has ideas. Besides, if we abstract the species, we can no longer imagine the existence of matter, and vice versa. I derived from Henriette as great happiness as that charming woman derived from me. We loved one another with all the strength of our faculties, and we were everything to each other. She would often repeat those pretty lines of the good La, Fontaine: ‘Soyez-vous l’un a l’autre un monde toujours beau, Toujours divers, toujours nouveau; Tenez-vous lieu de tout; comptez pour rien le reste.’ And we did not fail to put the advice into practice, for never did a minute of ennui or of weariness, never did the slightest trouble, disturb our bliss. The day after the close of the opera, Dubois, who was dining with us, said that on the following day he was entertaining the two first artists, ‘primo cantatore’ and ‘prima cantatrice’, and added that, if we liked to come, we would hear some of their best pieces, which they were to sing in a lofty hall of his country-house particularly adapted to the display of the human voice. Henriette thanked him warmly, but she said that, her health being very delicate, she could not engage herself beforehand, and she spoke of other things. When we were alone, I asked her why she had refused the pleasure offered by Dubois. “I should accept his invitation,” she answered, “and with delight, if I were not afraid of meeting at his house some person who might know me, and would destroy the happiness I am now enjoying with you.”
