What is the main conflict in Naturalism by ?

Naturalism applies both to scientific ideas and principles, such as instinct and Darwin's theory of evolution, and to fiction. Authors in this movement wrote stories in which the characters behave in accordance with the impulses and drives of animals in nature. The tone is generally objective and distant, like that of a botanist or biologist taking notes or preparing a treatise. Naturalist writers believe that truth is found in nature, and because nature operates within consistent principles, patterns, and rules, truth is consistent.
