There is a difference, however, between the novel which is purposely directive, the novel with a moral, so to speak, and the novel which is guided by a social drift, by "the spirit of the times." The former is liable to mediocrity and flatness, the latter is the patrimony of the loftiest minds. This spirit, this social sympathy, issued from every pore of Ivan Turguenief, the most able and exquisite of them all, indirectly and without detriment to his impersonality, and with the full conviction that it ought to be so; and novel-writing is useful in this way and no other. He says as much in a sort of autobiographical fragment, in which he explains how and why he left his country: "I felt that I must at all costs get away from my enemy in order the better to deal him a telling blow. And my enemy bore a well-known name; it was serfdom, slavery. Under the name of slavery I included everything that I proposed to fight without truce and to the death. This was my oath, and I was not alone in subscribing thereto. And in order to be faithful to it I came to the Occident." If I am not mistaken, the great difference between French and Russian naturalism lies in this predominant characteristic of social expression. The defects and merits of French naturalism are bound up with its condition as a purely literary insurrection and protest against the rhetoric of romanticism. In vain Zola exerts his Titanic energies to impress on his works this social significance, whose invigorating power is not unheeded by his perspicacious mind. He fights against egoism without and perhaps within; but only in the two which he conceives to be his master works, "L'Assommoir" and "Germinal," has he approached the desired mark.
