At any rate, the admirer of his novels may give her the benefit of the doubt, and remember in gratitude that she undoubtedly added to the gamut of the great psychologist's emotions, and therefore increased his knowledge of the human heart, and the truth and vividness of his books. Balzac, who spoke of the "doleurs qui font trop vivre," plunged very deeply into the learning of the school of life at this time. [*] "Correspondance," vol. i. p. 195. At last came a final rupture, of which we can only conjecture the cause, as no satisfactory explanation is forthcoming. The original "Confession" in the "Medecin de Campagne," which is the history of Balzac's relations and parting with Madame de Castries, is in the possession of the Vicomte de Spoelberch de Lovenjoul. The present Confession was substituted in its place, because the first revealed too much of Balzac's private life. However, even in the original Confession, we learn no reason for Madame de Castries' sudden resolve to dismiss her adorer, as Balzac declares with indignant despair that he can give no explanation of it. Apparently she parted from him one evening with her usual warmth of affection, and next morning everything was changed, and she treated him with the utmost coldness. Madame de Castries, with her brother-in-law, the Duc de Fitz-James and his family, had settled to leave Aix on October 10th, and to travel in Italy, visiting Rome and Naples; and they had been anxious that Balzac should be one of the party. At first Balzac only spoke of this vaguely, because of the question of money; but as pecuniary matters were never allowed to interfere with anything he really wanted to do, his mother cannot have been surprised to receive a letter written on September 23rd, telling her that the matter was settled, and that he was going to Italy.[*] As she would naturally ask how this was to be managed, he explains that he will put off paying a debt of 500 francs, and that, being only responsible for a fourth share in the hire of Madame de Castries' carriage, this money would suffice for his expenses as far as Rome. There he will require 500 francs, and the same amount again at Naples; but this money will be gained by the "Medecin de Campagne," and he will only ask Madame de Balzac for 500 francs--without which he will perhaps, after all, manage--to bring him back from Naples in March. On September 30th he writes to M. Mame, the publisher, to tell him about the nearly-finished "Medecin de Campagne," and still talks of his projected journey; but on October 9th, as a result of Madame de Castries' behaviour towards him, he has left her at Aix, and is himself at Annecy, and on October 16th he has travelled on to Geneva. His only explanation for his sudden change of plan is a vague remark to his mother about the 1,000 francs required for the journey,[+] and about the difficulty of publishing books while he is away from France; while on the real reason of his change of plan he is absolutely silent.
