And that is where we part company with the Goncourt brothers and their theory of art. We learn from them all about the experiences of a Paris prostitute; we learn the details of the life of a young society girl, brought up in a hot-house environment, a prey to abnormal cravings; we learn the symptoms of religious pathology, the half-sensuous hysteria of a woman in the toils of Catholic priestcraft. There are eight or ten such novels, each dealing with a different assortment of abnormalities; but nowhere in these books is there a hint of anything to be done, whether by individual conversion, the renewal of the moral forces, or by political and economic readjustments. All such things are rigidly excluded by the “naturalist” formula; and it is essential to get clear that the Goncourt brothers, who made the formula, made it because they were sick and impotent men, the victims of a decadent stage of civilization. They thought they were giving us scientific reports upon human life, when as a matter of fact what they were giving us were the by-products of their own headaches and dyspepsias. They toiled with the devotion of martyrs to report every quiver of their nervous sensibility; Edmond watched Jules while Jules was dying--Jules even watched himself--in order to report the details of this experience. Neither of them realized that, much as the world may need information about the sensations of dying, it has even more need of information about how to live. As for the Goncourt brothers, what they needed was fresh air and exercise. Fiction, according to this “naturalist” formula, was to become “exact science.” But then, there are many kinds of science. It is science to put a beetle under the microscope, and diagram the epidermal cells in its carapace. But science does not stop with such observation; it goes on to experiment. Supposing this beetle be dyed pink; will there be any trace of pink in its offspring, and does that prove the transmission of acquired characteristics? We have here in California a plant wizard who raises fields of flowers and fruits and vegetables. He is not content to accumulate facts about them, but proceeds to alter them--to make cactus without spines, and blackberries as big as your thumb, and wheat that is rust-proof and peaches that are scale-proof. Will some member of the Goncourt Academy explain why the “exact science” of fiction writing might not include an effort to free human beings from alcoholism and syphilis? As it happened, the greatest disciple of the Goncourt brothers, the man who took up their formula and used it to make himself the most widely read of all French novelists, came in the end to this very conclusion, and evolved into a moralist as intense and determined as Tolstoi.
