“I shall not be able to be a good judge, mademoiselle, I pass my life in writing. This is the first ball of this magnificence which I have ever seen.”

The young men with moustaches were scandalised.

“You are a wise man, Monsieur Sorel,” came the answer with a more marked interest. “You look upon all these balls, all these festivities, like a philosopher, like J. J. Rousseau. All these follies astonish without alluring you.”

Julien’s imagination had just hit upon an epigram which banished all illusions from his mind. His mouth assumed the expression of a perhaps slightly exaggerated disdain.

“J. J. Rousseau,” he answered, “is in my view only a fool when he takes it upon himself to criticise society. He did not understand it, and he went into it with the spirit of a lackey who has risen above his station.”

“He wrote the Contrat Social,” answered Mathilde reverently.

“While he preaches the Republic, and the overthrow of monarchical dignities, the parvenu was intoxicated with happiness if a duke would go out of his way after dinner to one of his friends.”

“Oh yes, the Duke of Luxembourg at Montmorency, used to accompany a Coindet from the neighbourhood of Paris,” went on Mademoiselle de la Mole, with all the pleasure and enthusiasm of her first flush of pedantry. She was intoxicated with her knowledge, almost like the academician who discovered the existence of King Feretrius.

Julien’s look was still penetrating and severe. Mathilde had had a moment’s enthusiasm. Her partner’s coldness disconcerted her profoundly. She was all the more astonished, as it was she who was accustomed to produce that particular effect on others.

At this moment the marquis de Croisenois was advancing eagerly towards mademoiselle de la Mole. He was for a moment three yards away from her. He was unable to get closer because of the crowd. He smiled at the obstacle. The young marquise de Rouvray was near her. She was a cousin of Mathilde. She was giving her arm to her husband who had only married her a fortnight ago. The marquis de Rouvray, who was also very young, had all the love which seizes a man who, having contracted a marriage of convenience exclusively arranged by the notaries, finds a person who is ideally pretty. M. de Rouvray would be a duke on the death of a very old uncle.
