The theme of Naturalism and its variuos aspects are dealt with this work. The narrative elucidates how one's background affects personality and behavior. Past may be left behind but its consequences are faced in the present. A unique theme that has been dealt with in the most idiosyncratic manner.
The novelist Frank Norris is almost forgotten today, but in books like "McTeague," published in 1899, he paved the way for a whole generation of American writers--a generation that included Theodore Dreiser and Sinclair Lewis and, less directly, Hemingway and Fitzgerald. McTeague is a dentist saddled with a grasping wife, and the book chronicles his rise and fall in awkward but powerful prose. This type of social realism, so contrary to the uplifting entertainment of the day (and to Mark Twain's more fanciful, comic novels), provided turn-of-the-century America a disturbing mirror in which to view itself.
