In fiction, Bourget carries realistic observation beyond the externals (which fixed the attention of Zola and Maupassant) to states of the mind: he unites the method of Stendhal to that of Balzac. He is always interesting and amusing. He takes himself seriously and persists in regarding the art of writing fiction as a science. He has wit, humor, charm, and lightness of touch, and ardently strives after philosophy and intellectuality -- qualities that are rarely found in fiction.
