"The Lord of the Flies" is a novel by William Golding that explores the dark side of human nature through the story of a group of boys stranded on an uninhabited island. The term "lord of the flies" has multiple interpretations and can be understood in different ways.

One quote that helps to understand the term comes from the book itself: "‘Fancy thinking the Beast was something you could hunt and kill!’ said the head. For a moment or two the forest and all the other dimly appreciated places echoed with the parody of laughter. ‘You knew, didn’t you? I’m part of you? Close, close, close! I’m the reason why it’s no go? Why things are what they are?’" (Golding, 143).

This quote alludes to the idea that the "lord of the flies" represents the evil that exists within each individual.
