Read this excerpt from The Adventures of Robinson Crusoe:
. . .I was very loth to sell [Xury], who had assisted me so faithfully in procuring my own [freedom]. However, when I let [the captain] know my reason, . . . [he] offered me this medium, that he would give the boy an obligation to set him free in ten years, if he turned Christian.What does this passage reveal about the times Defoe was writing about?
