Naturalism is the application of the principles of scientific determinism to literature. This can be seen in characters who, as animals in nature, respond to environmental forces and internal stresses and drives, none of which they can control or understand. While realism focuses on the commonplace, naturalism focuses on the representative and arranges details so as to reveal certain patterns of ideas that form the author's view of life. Naturalistic works will often emphasize either a biological or socio-economic determinism, one that is inescapable for those involved.
