Novels of the 20th century underwent significant changes in form and style compared to previous eras. Chapters were broken into fragments and sentences dissolved into streams of interior thought, influenced by Freudian psychology and Marxism. Truth became relative and novels dealt in no absolutes. Traditional narration was replaced with subjective perspectives that emphasized consciousness over plot and character coherence. The past was discovered imperfectly through effort. Dominant themes included facing reality, social awareness, and loneliness. Experimental styles flourished alongside realism, with an emphasis on perspective and portraying the human condition through moving dramas. Minority literature also grew in the later decades.
