Why this novel is titled, "Sound and the Fury" and what is an allusion to.

To start off, this title is a reference to the Scottish tragedy, "Macbeth", telling the reader the moment they pick up the book that is is not going to be a happy story. The quote itself is from Shakespeare, and it is the moment Macbeth realizes that everything isn't worth it anymore. By titling the novel a direct quote from the Scottish play, Faulkner is conveying to the reader that the story is not going to proceed in harmony. All the characters will have a different influence towards Benji, but they will not always be a good one.
