In the preface to the English translation (_The Downfall_. London: Chatto & Windus) Mr. E. A. Vizetelly quotes from an interview with Zola regarding his aim in writing the work. A novel, he says, “contains, or may be made to contain, everything; and it is because that is my creed that I am a novelist. I have, to my thinking, certain contributions to make to the thought of the world on certain subjects, and I have chosen the novel as the best way of communicating these contributions to the world. Thus _La Debacle_, in the form of a very precise and accurate relation of a series of historical facts--in other words, in the form of a realistic historical novel--is a document on the psychology of France in 1870. This will explain the enormous number of characters which figure in the book. Each character represents one _etat d’ame psychologique_ of the France of the day. If my work be well done, the reader will be able to understand what was in men’s minds and what was the bent of men’s minds--what they thought and how they thought at that period.”
In this, the concluding novel of the Rougon-Macquart series, Zola gathers together the threads of the preceding volumes and makes a vigorous defence of his theories of heredity. The story in the book is both simple and sad. Doctor Pascal Rougon, a medical man at Plassans and a distinguished student of heredity, had brought up his niece Clotilde (daughter of Aristide Rougon alias Saccard) from childhood. Years afterwards they found that they passionately loved one another, but they did not marry, as Pascal, who had lost money, thought that by doing so she would sacrifice her interests. (In this connection it is right to mention that marriage between an uncle and a niece is legal in France, and is not uncommon.) With fine self-sacrifice Pascal persuaded Clotilde to go to Paris to live with her brother who was wealthy and wanted her to nurse him. Soon after her departure Pascal showed symptoms of a fatal affection of the heart, and after some weeks of great suffering telegraphed for Clotilde to come back. One hour before her return he died. His mother, Madame Felicite Rougon, who feared that his researches on heredity might bring scandal on the family, burned all his papers, and in one hour destroyed the work of a lifetime. A child was born to Clotilde seven months after the death of Doctor Pascal; a child which he intensely desired, in the hope that through it might come the regeneration and rejuvenation of his race.
