Definition for Naturalism
From Biology Forums Dictionary
Naturalism in the theatre (late 19th century) is a style closely related to realism. It also insisted on the truthful depiction of life, but naturalism went on to insist on the basic principle that behavior is determined by heredity and environment. Absolute objectivity, not personal opinion, was the naturalist’s goal. Naturalism in opera (late 19th century) was a counter-reaction to Romanticism. It opposed stylization, although it maintained exotic settings and included brute force and immorality. Its texts are in prose rather than poetry, and its settings appear lifelike.
