It provides background on the author Daniel Defoe and discusses how Crusoe establishes dominance over the native he names Friday on the island, forcing him to convert to Christianity and view Crusoe as his master. The document argues that the novel idealizes the master-servant dynamic and represents a colonial view of the relationship between Europeans and non-white peoples, with Crusoe symbolizing the colonizer and Friday the colonized. It concludes that the novel reflects the morality of its time, which saw exploiting subjugated populations in places like Africa and Asia.
