We are here arrived at a very fitting point to pass on and consider that third misconception of the relation between science and art, which has been recently formulated by M. Emile Zola in his work called _Le Roman Expérimental_. Zola's name has been so widely associated with a certain class of novels, that I am fortunately under no necessity to describe them, and I need only say that the work in question is a formal reply to a great number of objections which have come from many quarters as to the characters and events which Zola's novels have brought before the public. His book, though a considerable volume, may be said to consist of two sentences which the author has varied with great adroitness into many forms. These two sentences I may sum up, as follows: (1) every novel must hereafter be the entirely unimaginative record of an experiment in human passion; and (2) every writer of the romantic school in France, particularly Victor Hugo, is an ass. You are not to suppose that in this last sentiment I have strengthened Zola's expressions. A single quotation will show sufficient authority. As, for example, where M. Zola cries out to those who are criticizing him: "Every one says: 'Ah yes, the naturalists! they are those men with dirty hands who want all novels to be written in slang, and choose the most disgusting subjects.' Not at all! you lie!... Do not say that I am idiot enough to wish to paint nothing but the gutter." But with this quarrel we are not here concerned; I simply wish to examine in the briefest way Zola's proposition to convert the novel into a work of science. His entire doctrine may be fairly, indeed amply gathered in the following quotations: "We continue by our observations and experiments the work of the physiologist, who has himself employed that of the physicist and the chemist. We after a fashion pursue scientific psychology in order to complete scientific physiology; and in order to complete the evolution, we need only carry to the study of nature and man the invaluable tool of the experimental method. In a word, we should work upon characters, passions, human and social facts, as the physicist and chemist work with inorganic bodies, as the physiologist works with living organisms. Determinism controls everything.
