How does literary theory change a literary text

Literary theory allows readers to consider aspects of a text, or film, or any part of culture in fact, to be read in an entirely different way to how they may have been thinking before. It therefore, prompts discussion on an author’s ideology and intentions, when they were writing.
In relation to a literary text, in this case Emily Brontë’s Wuthering Heights, by applying two separate theories on to the text, we gain different perspectives of its characters and on the texts meaning, and also on the underlying views of the author and how it influenced their writing, even if they were not explicitly aware of this. Here, I will be using a feminist and Marxist reading of Wuthering Heights to show how these perspectives change the way we read this 19th Century novel.
