The rise of naturalism in American letters was born out of a reaction against romanticism by writers such as Theodore Dreiser, Hamlin Garland, Stephen Crane, Frank Norris, Jack London, Upton Sinclair and Robert Herrick, who attempted to rid the American novel of romanticism by delving deeper into life's truths than did the realists Mark Twain, William Dean Howells and Henry James. The naturalists objected to the limited subject matter of the realists; they focused their attention on "slums, crime, illicit sexual passions, exploitation of man by man"2 and other actualities of the world. George Perkins outlined other distinctions between realism and naturalism in American literature.3 He describes nineteenth-century realism, 1870-1890, as represented by writers who created a world of truth by keeping actuality clearly in mind. The emphasis was on the following: 1. Using settings that were thoroughly familiar to the writer. 2. Emphasizing the norm of daily experience in plot construction. 3. Creating ordinary characters and studying them in depth. 4. Adhering to complete authorial objectivity. 5. Accepting their moral responsibility by reporting the world as it truly was.
