Courfeyrac, who was a practical man, was not pleased with this reflection of an invisible Paradise cast on Marius; he was but little accustomed to unpublished passions, hence he grew impatient, and at times summoned Marius to return to reality. One morning he cast this admonition to him,-- "My dear fellow, you produce on me the effect at present of being a denizen of the moon, in the kingdom of dreams, the province of illusion, whose chief city is soap-bubble. Come, don't play the prude,--what is her name?" But nothing could make Marius speak, and his nails could have been dragged from him more easily than one of the three sacred syllables of which the ineffable name _Cosette_ was composed. True love is luminous as the dawn, and silent as the tomb. Still Courfeyrac found this change in Marius, that he had a beaming taciturnity. During the sweet month of May, Marius and Cosette knew this immense happiness,--to quarrel and become reconciled, to talk for a long time, and with the most minute details, about people who did not interest them the least in the world,--a further proof that in that ravishing opera which is called love, the libretto is nothing. For Marius it was heaven to listen to Cosette talking of dress; for Cosette to listen to Marius talking politics, to listen, knee against knee, to the vehicles passing along the Rue de Babylone, to look at the same planet in space, or the same worm glistening in the grass, to be silent together, a greater pleasure still than talking, etc. Still various complications were approaching. One evening Marius was going to the rendezvous along the Boulevard des Invalides; he was walking as usual with his head down, and as he was turning the corner of the Rue Plumet, he heard some one say close to him,-- "Good-evening, Monsieur Marius." He raised his head and recognized Éponine. This produced a singular effect; he had not once thought of this girl since the day when she led him to the Rue Plumet; he had not seen her again, and she had entirely left his mind. He had only motives to be grateful to her, he owed her his present happiness, and yet it annoyed him to meet her. It is an error to believe that passion, when it is happy and pure, leads a man to a state of perfection; it leads him simply, as we have shown, to a state of forgetfulness. In this situation, man forgets to be wicked, but he also forgets to be good, and gratitude, duty, and essential and material recollections, fade away. At any other time Marius would have been very different to Éponine, but, absorbed by Cosette, he had not very clearly comprehended that this Éponine was Éponine Thénardier, and that she bore a name written in his father's will,--that name to which he would have so ardently devoted himself a few months previously. We show Marius as he was, and his father himself slightly disappeared in his mind beneath the splendor of his love. Hence he replied with some embarrassment,-- "Ah, is it you, Éponine?"
