<human>:  Differentiate between naturalism and realism in literature.
<bot>: Naturalism and realism are both genres of literature that share some similarities, but also have several distinct differences. Naturalism is a literary movement that emerged in the late 19th century, which emphasizes objectivity and accuracy in the portrayal of life, often highlighting the struggles and tragedies of everyday life. Naturalism often incorporates elements of science and philosophy, to present an unflinching view of life’s harshness and futility. In contrast, realism is a style of literature that focuses on accurately depicting mundane, everyday life and events, oftentimes with a subtle dose of humor. Realism, unlike naturalism, often employs sympathetic narratives and hopeful tones, aiming to show how ordinary people can triumph over adversity.
