The most important theme of the 1960 Pulitzer Prize winning novel To Kill a Mockingbird is author Harper Lee’s tenacious exploration of the moral nature of people. Lee tenaciously explores the moral nature of human beings, especially the struggle in every human soul between discrimination and tolerance.
