M. Bergeret's private life is turned upside down, when he discovers that his wife deceived him with his best pupil, M. Roux. He then decides he will no longer talk to his wife. He subjects her to this slow but effective moral torture, and it bears fruit: by the end of the novel, she decides to leave the marital home. M. Bergeret, however, suffers too, chiefly his pride. He seeks consolation in books and ideas, and this has consequences for his thoughts and conversation. He makes bitter remarks about life, which he sees as one long agony, and on his contemporaries, which he compares with chimpanzees.
