Final answer:
Contradictions in literature are necessary because they add complexity and depth to the story, help establish themes, and encourage critical thinking.
Step-by-step explanation:
A story can have more than one theme, and it is often useful to question and analyze how the themes interact. Contradictions in literature can be necessary in order to establish a theme. They can create tension, complexity, and depth in the story, allowing the reader to explore different perspectives and ideas. Contradictions can also challenge the reader's assumptions and provoke critical thinking.
For example, in the novel 'To Kill a Mockingbird' by Harper Lee, the theme of racism is established through contradictions. On the one hand, the town of Maycomb is depicted as a close-knit community with a strong sense of morality and justice. However, the reality is that racism and prejudice are deeply ingrained in the society, as seen in the unjust trial of Tom Robinson. The contradictions between the town's ideals and its actions highlight the pervasive nature of racism and contribute to the exploration of the theme.
In conclusion, contradictions in literature are necessary because they add complexity and depth to the story, help establish themes, and encourage critical thinking.
