I have to write a Thesis and a Literary Analysis on "Out of the Silent Planet" by C.S Lewis in APA and I don't know how to begin. I need help ASAP.

A good thesis relies on a specific argument. You need to come up with one first by considering the book's thematic importance. Out of the silent planet is certainly a Christian allegory. Beyond that, it is about the evils of Colonialism. The British Empire, at its peak in the late 19th Century, had colonies around the world. Beginning in the first half of the 20th Century, many of these colonies began independence movements to gain control of their own government. These movements, such as the one led by Mohandas Gandhi in India, proved to be successful in the years following World War II. India gained independence in 1948. At the time C.S. Lewis wrote Out of the Silent Planet, in the early 1940's, the subject of colonization and Britain's role in the world was a topic of much discussion. The attitude of the character Weston is an example of how many British people felt about less developed cultures during the height of colonial expansion. Many felt Britain's advanced military, medicine and science gave it the right and even the responsibility to rule over people who were not as advanced. This attitude is closely tied to racism, as many of Britain's colonial territories were in Africa and Asia. The perceived responsibility to rule over other peoples was sometimes referred to as the "White Man's Burden," a phrase the character Devine uses in the novel. It was up to white men, they thought, to bring civilization to the other races of the world.
