Daniel Defoe's critique of monarchs' divine right is the focus of this article. Defoe's critique of divine right is considered to be mostly based on his understanding of human nature and social origins. While proponents of the divine right doctrine frequently quote Old Testament texts to support their claims, Defoe interprets the same verses differently from them based on his understanding of human nature. This study finds that the argument between the two groups has a considerably older tradition of biblical interpretation. The paper points out that Defoe's reading is often based on the original sin of the monarch, which at the same time shows the connection between his view of human nature and his political thought.
