What "naturalism" means in literature

A term you'll meet in literary history and realist fiction.

Literary naturalism is an extension of realism that hardened into something darker. Where realism sought to represent social life accurately, naturalism added a philosophical claim: human beings are products of their heredity and environment, driven by forces — biological, economic, psychological — they neither fully understand nor control. Free will, in the strict sense, is an illusion. Character is fate, and fate is determined before the character even appears on the page.

The philosophical background

Naturalism emerged in the 1870s–80s, shaped by Darwinian evolutionary biology and Hippolyte Taine's influential formula: race, milieu, moment. Taine argued that a person's character and a nation's literature could be explained by three factors: inherited racial characteristics, the physical and social environment, and the historical moment. Apply this to fiction and you get characters who are, in Zola's terms, human "documents" — specimens in a scientific study of how heredity and milieu determine behavior.

Émile Zola was the movement's theorist and practitioner. His 1880 essay "Le Roman expérimental" (The Experimental Novel) proposed that the novelist should operate like a scientist — constructing controlled experiments with characters in specific environments, observing what follows. The novel becomes a lab report on human nature.

Characteristics of naturalist fiction

• Determinism. Characters do not transcend their origins. The shopgirl who grew up in poverty will not rise through virtue; she will be destroyed by forces already in motion before her first scene.
• Lower-class subjects. Naturalist fiction characteristically descends to the working class, the urban poor, the immigrant, the gambler, the prostitute. These are environments where the brute forces of appetite, poverty, and heredity are most visible.
• Unglamorous detail. Naturalist writers document what polite fiction avoided: hunger, violence, alcoholism, sexual coercion, bodily degradation. This is not sensationalism for its own sake but an insistence that art look at what is actually there.
• Absence of redemption. Unlike Victorian fiction, where suffering tends toward transformation or reconciliation, naturalist plots often end in destruction or stasis. Characters are worn down, not built up.

Key texts

Zola's Rougon-Macquart cycle (1871–1893) — twenty novels tracing a single family across five generations, demonstrating how hereditary "taint" (alcoholism, mental instability) plays out differently across the social spectrum. Germinal (1885) is his masterpiece: coal miners in conditions that reduce them to the forces of appetite and survival.

Stephen Crane, Maggie: A Girl of the Streets (1893) — a slum girl destroyed by her environment, the first American naturalist novel. Crane does not sentimentalize Maggie; he documents her.

Frank Norris, McTeague (1899) — a dentist whose animal nature gradually overwhelms his veneer of civilization. The novel is grimly Darwinian: human nature as a set of drives barely held in check by social convention.

Theodore Dreiser, Sister Carrie (1900) — a country girl who rises and falls in Chicago, driven by desire and circumstance rather than moral choice. Dreiser refuses the Victorian moral: Carrie is not punished for her transgressions because the universe is not moral in that way.

Naturalism vs. realism

Both movements value accurate representation of social life, but they differ on agency. Realist characters — even in grim circumstances — typically retain some capacity for moral choice and its consequences. Naturalist characters are substantially determined. Middlemarch's characters choose; Germinal's characters are chosen for. Realism represents a world where character is destiny; naturalism represents a world where destiny is chemistry, heredity, and economic position.
