Abstract: “Looking for Mr. Green” is a famous short story of Saul Bellow who is an American novelist and the Nobel Prize winner for literature. The paper analyzes zero as goodness and different peoples pursuit of zero of goodness and different images of deviation embodied by the pursuit in the story with the binary relation of zerodegree and deviation in rhetoric. Mr. Green is an embodiment of goodness. He penetrates the whole story with the form of a vacant zero and is shown by different peoples pursuit of goodness. With the description of Mr. Green and his deviation images，Bellow expresses his idea that the persistent pursuit of goodness is the foundation that makes a man human being.
